adapalene

minocycline

Adapalene Gel 0.1% Versus Placebo as Prophylaxis for Anti-Epidermal Growth Factor Receptor-Induced Acne-Like Rash: A Randomized Left-Right Comparative Evaluation (APPEARANCE).  The results of the APPEARANCE trial indicate that adapalene does not prevent acne-like rash over placebo when added to topical moisturizer and oral minocycline but instead may have a detrimental effect . Therefore, adapalene is not recommended as prophylaxis against acne-like rash induced by anti-epidermal growth factor receptor therapies.Given that acne-like rash was completely controlled with placebo in approximately half of patients, predictive measures to identify patients needing intensive prophylaxis are required. ### background Anti-epidermal growth factor receptor (EGFR) therapies are frequently associated with acne-like rash. To evaluate the prophylactic efficacy of adapalene, a topical retinoid used as first-line therapy for acne vulgaris, we conducted a randomized, placebo-controlled, evaluator-blinded, left-right comparative trial. ### methods Patients with non-small cell lung, colorectal, or head and neck cancer scheduled to receive anti-EGFR therapies were randomly assigned to once-daily adapalene application on one side of the face, with placebo on the other side. All patients had topical moisturizer coapplied to both sides of the face, and received oral minocycline. The primary endpoint was the difference in total facial lesion count of acne-like rash at 4 weeks. Secondary endpoints included complete control rate (CCR) of acne-like rash (≤5 facial lesions) and global skin assessment (Investigator's Global Assessment [IGA] scale, grade 0-4) at 4 weeks. Two blinded dermatologists independently evaluated the endpoints from photographs. ### results A total of 36 patients were enrolled, of whom 26 were evaluable. adapalene treatment was associated with a greater lesion count than placebo at 4 weeks, although the difference was not statistically significant (mean, 12.6 vs. 9.8, ### conclusion adapalene is not recommended as prophylaxis against acne-like rash induced by anti-EGFR therapies.


cyclophosphamide

methotrexate

prednisone

doxorubicin

Randomized comparison of two combination chemotherapy regimens containing doxorubicin in patients with metastatic breast cancer: a Western Cancer Study Group trial. Ninety-six patients with metastatic breast cancer were entered in a prospectively randomized trial comparing a five-drug doxorubicin (Adriamycin)-containing regimen given in two different schedules. Both regimens included cyclophosphamide , methotrexate , 5-FU , prednisone , and doxorubicin . On one schedule, referred to as "combination" treatment, doxorubicin was given every 21 days and cyclophosphamide was given daily. On the less intensive "fixed-rotation" schedule, doxorubicin was given on alternative cycles every 42 days and cyclophosphamide was given for 21 days of the 42-day cycle. Response frequency and survival were comparable among patients receiving either regimen. Significantly less (P < 0.05) nausea and leukopenia occurred on the fixed-rotation schedule. Therefore, similar therapeutic benefit along with decreased toxicity was obtained by use of combination chemotherapy involving doxorubicin and cyclophosphamide given in the less intensive schedule.


peginterferon alfa-2b

vemurafenib

ipilimumab

Cutaneous melanoma: new advances in treatment. Cutaneous melanoma is a challenge to treat. Over the last 30 years, no drug or combination of drugs demonstrated significant impact to improve patient survival. From 1995 to 2000, the use of cytokines such as interferon and interleukin become treatment options. In 2011 , new drugs were approved by the U.S. Food and Drug Administration , including peginterferon alfa-2b for patients with stage III disease , vemurafenib for patients with metastatic melanoma with the BRAF V600E mutation , and ipilimumab , a monoclonal antibody directed to the CTLA-4 T lymphocyte receptor , to combat metastatic melanoma in patients who do not have the BRAF V600E mutation . Both ipilimumab and vemurafenib showed results in terms of overall survival. Other trials with inhibitors of other genes, such as the KIT gene and MEK, are underway in the search for new discoveries. The discovery of new treatments for advanced or metastatic disease aims to relieve symptoms and improve patient quality of life.


bicalutamide

flutamide

Combination hormonal therapy: a reassessment within advanced prostate cancer. Combination hormonal therapy, comprising a luteinising hormone-releasing hormone analogue (LHRHa) with an antiandrogen, is widely used in the treatment of advanced prostate cancer. There is ongoing debate regarding the use of combination hormonal therapy as opposed to LHRHa monotherapy. The pivotal consideration is whether there are adequate benefits with combination hormonal therapy in terms of increased survival and decreased disease progression to outweigh the increased risk of adverse events and additional cost. The most recent meta-analysis by the Prostate Cancer Trialists' Collaborative Group indicates a small but statistically significant survival benefit with combination hormonal therapy using nonsteroidal antiandrogens. It is, however, noteworthy that combined conclusions derived from such meta-analyses may not apply across each of the individual antiandrogens. Individual studies have reported differences between antiandrogens in terms of both tolerability and efficacy-for example , bicalutamide has been shown to be better tolerated than flutamide , and may be associated with improved survival . In addition, it is essential that treatment decisions are taken in consultation with the patient. Owing to an increasing proportion of cases presenting with early-stage disease, combination hormonal therapy is increasingly used in the neoadjuvant or adjuvant setting with radiotherapy and, in cases of prostate-specific antigen recurrence after prior localised therapy. Further data are awaited to optimise the use of combination hormonal therapy in these new settings.


Montelukast

Levocetirizine

A Randomized , Multicenter , Double-blind , Phase III Study to Evaluate the Efficacy on Allergic Rhinitis and Safety of a Combination Therapy of Montelukast and Levocetirizine in Patients With Asthma and Allergic Rhinitis . The aim of this study was to evaluate the efficacy and safety of a fixed-dose combination of montelukast and levocetirizine in patients with perennial allergic rhinitis with mild to moderate asthma compared with the efficacy and safety of montelukast alone. ### methods This study was a 4-week, randomized, multicenter, double-blind, Phase III trial. After a 1-week placebo run-in period, the subjects were randomized to receive montelukast (10 mg/day, n = 112) or montelukast (10 mg/day)/levocetirizine (5 mg/day) (n = 116) treatment for 4 weeks. The primary efficacy end point was mean daytime nasal symptom score. Other efficacy end points included mean nighttime nasal symptom score, mean composite symptom score, overall assessment of allergic rhinitis by both subjects and physicians, forced expiratory volume in 1 second (FEV ### findings Of 333 patients screened for this study, 228 eligible patients were randomized to treatment. The mean (SD) age of patients was 43.32 (15.02) years, and two thirds of subjects were female (66.67%). The demographic characteristics were similar between the treatment groups. Compared with the montelukast group, the montelukast/levocetirizine group reported significant reductions in mean daytime nasal symptom score (least squares mean [SE] of combination vs montelukast, -0.98 [0.06] vs -0.81 [0.06]; P = 0.045). For all other allergic rhinitis efficacy end points, the montelukast/levocetirizine group showed greater improvement than the montelukast group. Similar results were observed in overall assessment scores and in FEV ### implications The fixed-dose combination of montelukast and levocetirizine was effective and safe in treating perennial allergic rhinitis in patients with asthma compared with montelukast alone. ClinicalTrials.gov identifier: NCT02552667.


cefoperazone

sulbactam

Multiple-dose pharmacokinetics and toleration of intravenously administered cefoperazone and sulbactam when given as single agents or in combination. The multiple-dose pharmacokinetics and toleration of cefoperazone (3 g every 12 h) and sulbactam (1.5 g every 12 h) were studied when these antimicrobial agents were administered continuously over 7 days as a 15-min infusion of individual agents and as a 3/1.5-g cefoperazone-sulbactam combination. Fourteen male volunteers participated in an open, three-way crossover study of Latin Square design with a 1-week washout period between phases. On days 1 and 7 of each phase, serial serum samples and urine were collected for drug assay over a 12-h period. Hematological and clinical chemistry determinations were made within 10 days before the first antibiotic dose and for each treatment phase just before the first dose, on day 4 of treatment, and within 24 h of the last dose. For cefoperazone as a single agent on days 1 and 7, the average maximal concentration in serum (Cmax) was approximately 430 micrograms/ml, the terminal elimination half-life (t1/2) was 1.8 h, and the average percentage of dose excreted unchanged in the urine (%Ur) was 30%. For sulbactam as a single agent, the Cmax was approximately 90 micrograms/ml, the t1/2 was 1 h, and the %Ur was 89% on days 1 and 7. When comparing individual versus simultaneous drug administration, the only pharmacokinetic alteration observed was a statistically significant but minor (about 10%) decrease in sulbactam renal clearance, on both days 1 and 7, resulting in a similar decrease in total body clearance (CL). The area under the curve, apparent volume of distribution by the area method (V), t1/2, and Cmax were not significantly altered. Although cefoperazone pharmacokinetic parameters were not significantly altered when comparing single-agent to combination drug administration, the area under the curve was slightly lower and CL, nonrenal clearance, and V were modestly higher from day 1 to day 7. Because Cmax and t1/2 were unaffected, these minor day effects would not be of clinical significance. Intravenous administration of cefoperazone and sulbactam given as individual agents compared with the combination did not show pharmacokinetic differences that are likely to produce clinically relevant effects . The combination of cefoperazone and sulbactam was well tolerated, and the safety profile of the combination was similar to that either drug given alone under the conditions of this study.


cyclophosphamide

carmustine

thiotepa

Interleukin-2 and granulocyte-macrophage-colony-stimulating factor immunomodulation with high-dose chemotherapy and autologous hematopoietic stem cell transplantation for patients with metastatic breast cancer. Immunomodulation with cytokines was used to improve the result of high-dose chemotherapy (HDC)/autologous hematopoietic stem cell transplantation (AHST). We examined the use of IL-2 and growth factors for mobilization, ex vivo activation of peripheral blood stem cell (PBSC) and maintenance therapy after HDC/AHST in metastatic breast cancer. Eligible patients with metastatic breast cancer for HDC/AHST were assigned to 1 of 3 protocols for PBSC mobilization: G-CSF (group 1); IL-2 + G-CSF (group 2); or IL-2 + G-CSF + GM-CSF (group 3). HDC with cyclophosphamide , carmustine and thiotepa was given from day -7 to -5 . PBSCs were treated ex vivo with IL-2 for 24 h and reinfused on day 0. Maintenance therapy included low-dose IL-2, followed by 2 courses of intermediate-dose IL-2. GM-CSF was given from day 1 until neutrophil recovery. Thirty-four patients (10 in group 1, 14 in group 2, and 10 in group 3) were included. Comparable numbers of CD34(+) cells were collected from all 3 groups; incremental increases of CD3(+) cells were collected from groups 1 to 2 and to 3 (p = 0.03). Major adverse effects from IL-2 were fever, hypotension and fatigue; no treatment-related mortality was seen. At a median follow-up of 790.5 days (range 150-2,722 days), median progression-free survival was 434 days and median overall survival was 1,432 days. Estimated 3-year progression-free and overall survival rates were 31 and 57%. Our study suggested that the use of IL-2 and growth factors immunomodulation with HDC/AHST was feasible with comparable survival rates.


Melatonin

sulpiride

Controlling retinal pigment epithelium injury after experimental detachment of the retina. Damage induced by detachment of the neural retina and the retinal pigment epithelium (RPE) can be reduced by dark adaptation. The authors evaluated the influence of the duration of dark adaptation, time of day, and modification of the melatonin-dopamine pathway on acute RPE lesions induced by mechanical detachment. ### methods BALB/c mice were studied at different times of day and different periods of dark adaptation. Some mice were treated with melatonin or sulpiride, a D2 dopamine receptor antagonist. Enucleated eyes and different saline solutions were used in experiments ex vivo. Retinal detachments in vivo were made by subretinal injections of hyaluronic acid. RPE cell damage was quantitatively evaluated with a dye exclusion procedure, and their viability was tested by preservation of tight junctions in culture. Lectin histochemistry was used to examine the interphotoreceptor matrix (IPM). ### results Significant propidium iodide (PI) incorporation in RPE cells was detected after ex vivo separation during daytime, but it was very low when detachment took place at night after 24 to 48 hours of dark adaptation. PI exclusion was achieved during daytime after a single hour of dark adaptation when mice were pretreated with melatonin or sulpiride. Reduction of RPE cell damage was accompanied by decreased lectin binding to cone sheaths. ### conclusions A combination of time of day and length of dark adaptation decreased damage induced by detachment of the retina ex vivo and in vivo. Melatonin or sulpiride could replace these environmental factors . Therefore, melatonin and dopamine pathways might be involved in the control of IPM properties and retina/RPE interactions.


Trastuzumab

Pertuzumab

Trastuzumab and Pertuzumab Plant Biosimilars : Modification of Asn297-linked Glycan of the mAbs Produced in a Plant with Fucosyltransferase and Xylosyltransferase Gene Knockouts . Plant biosimilars of anticancer therapeutic antibodies are of interest not only because of the prospects of their practical use, but also as an instrument and object for study of plant protein glycosylation. In this work, we first designed a pertuzumab plant biosimilar (PPB) and investigated the composition of its Asn297-linked glycan in comparison with trastuzumab plant biosimilar (TPB). Both biosimilars were produced in wild-type (WT) Nicotiana benthamiana plant (PPB-WT and TPB-WT) and transgenic ΔXTFT N. benthamiana plant with XT and FT genes knockout (PPB-ΔXTFT and TPB-ΔXTFT). Western blot analysis with anti-α1,3-fucose and anti-xylose antibodies, as well as a test with peptide-N-glycosidase F, confirmed the absence of α1,3-fucose and xylose in the Asn297-linked glycan of PPB-ΔXTFT and TPB-ΔXTFT. Peptide analysis followed by the identification of glycomodified peptides using MALDI-TOF/TOF showed that PPB-WT and TPB-WT Asn297-linked glycans are mainly of complex type GnGnXF. The core of PPB-WT and TPB-WT Asn297-linked GnGn-type glycan contains α1,3-fucose and β1,2-xylose, which, along with the absence of terminal galactose and sialic acid, distinguishes these plant biosimilars from human IgG. Analysis of TPB-ΔXTFT total carbohydrate content indicates the possibility of changing the composition of the carbohydrate profile not only of the Fc, but also of the Fab portion of an antibody produced in transgenic ΔXTFT N. benthamiana plants. Nevertheless, study of the antigen-binding capacity of the biosimilars showed that absence of xylose and fucose residues in the Asn297-linked glycans does not affect the ability of the glycomodified antibodies to interact with HER2/neu positive cancer cells.


trastuzumab

vinorelbine

vinorelbine

New combinations with Herceptin in metastatic breast cancer. Preclinical data indicate that trastuzumab (Herceptin) has the potential for synergistic or additive effects in combination with therapies including chemotherapy and hormonal agents, providing the rationale for a number of clinical trials in women with HER2-positive metastatic breast cancer. A recently reported phase II trial has demonstrated that trastuzumab plus vinorelbine is both effective ( overall response rate 75 % ) and well tolerated , with the major side effects being typical of single-agent vinorelbine . Other combinations of trastuzumab with a variety of other chemotherapeutic and hormonal agents are also being assessed. In an effort to overcome the cardiotoxicity observed with trastuzumab plus doxorubicin in the pivotal phase III trial, combination regimens involving potentially less toxic anthracyclines such as epirubicin and liposomal formulations of doxorubicin are ongoing. In addition, trials are investigating whether trastuzumab can reverse the resistance to hormonal therapy that develops in most women with metastatic breast cancer. These and other studies will identify the regimens that produce the best outcomes with the fewest possible side effects in women with HER2-positive breast cancer.


leuprorelin

goserelin

cyproterone

Quality of life compared during pharmacological treatments and clinical monitoring for non-localized prostate cancer: a randomized controlled trial. To investigate the effects of different management strategies for non-localized prostate cancer on men's quality of life and cognitive functioning. ### Patients Subjects And Methods Men with prostate cancer were randomly assigned to one of four treatment arms : leuprorelin , goserelin , cyproterone acetate ( CPA ) , or close clinical monitoring . In a repeated-measures design, men were assessed before treatment (baseline) and after 6 and 12 months of treatment. A community comparison group of men of the same age with no prostate cancer participated for the same length of time. The men were recruited from public and private urology departments from university teaching hospitals. All those with prostate cancer who were eligible for hormonal therapy had no symptoms requiring immediate therapy. In all, 82 patients were randomized and 62 completed the 1-year study, and of the 20 community participants, 15 completed the study. The main outcome measures were obtained from questionnaires on emotional distress, existential satisfaction, physical function and symptoms, social and role function, subjective cognitive function, and sexual function, combined with standard neuropsychological tests of memory, attention, and executive functions. ### results Sexual dysfunction increased for patients on androgen-suppressing therapies, and emotional distress increased in those assigned to CPA or close clinical monitoring. Compared with before treatment there was evidence of an adverse effect of leuprorelin, goserelin, and CPA on cognitive function. ### conclusions In deciding the timing of androgen suppression therapy for prostate cancer, consideration should be given to potential adverse effects on quality of life and cognitive function.


amantadine

mycophenolate

Aminoadamantanes versus other antiviral drugs for chronic hepatitis C. Hepatitis C virus infection affects around 3% of the world population or approximately 160 million people. A variable proportion (5% to 40%) of the infected people develop clinical symptoms. Hence, hepatitis C virus is a leading cause of liver-related morbidity and mortality with hepatic fibrosis, end-stage liver cirrhosis, and hepatocellular carcinoma as the dominant clinical sequelae. Combination therapy with pegylated (peg) interferon-alpha and ribavirin achieves sustained virological response (that is, undetectable hepatitis C virus RNA in serum by sensitivity testing six months after the end of treatment) in approximately 40% to 80% of treated patients, depending on viral genotype. Recently, a new class of drugs have emerged for hepatitis C infection, the direct acting antivirals, which in combination with standard therapy or alone can lead to sustained virological response in 80% or more of treated patients. Aminoadamantanes, mostly amantadine, are antiviral drugs used for the treatment of patients with chronic hepatitis C. We have previously systematically reviewed amantadine versus placebo or no intervention and found no significant effects of the amantadine on all-cause mortality or liver-related morbidity and on adverse events in patients with hepatitis C. Overall, we did not observe a significant effect of amantadine on sustained virological response. In this review, we systematically review aminoadamantanes versus other antiviral drugs. ### objectives To assess the beneficial and harmful effects of aminoadamantanes versus other antiviral drugs for patients with chronic hepatitis C virus infection by conducting a systematic review with meta-analyses and trial sequential analyses of randomised clinical trials. ### Search Methods The Cochrane Hepato-Biliary Group Controlled Trials Register (1996 to December 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 11 of 12, 2013), MEDLINE (1946 to December 2013), EMBASE (1974 to December 2013), Science Citation Index EXPANDED (1900 to December 2013), the WHO International Clinical Trials Registry Platform (www.who.int/ictrp), Google Scholar, and Eudrapharm up to December 2013. Furthermore, full text searches were conducted until December 2013. ### Selection Criteria Randomised clinical trials assessing aminoadamantanes in participants with chronic hepatitis C virus infection. ### Data Collection And Analysis Two authors independently extracted data. RevMan Analysis was used for statistical analysis of dichotomous data using risk ratio (RR) with 95% confidence intervals (CI). Methodological domains were used to assess the risk of systematic errors ('bias'). We used trial sequential analysis to assess risk of random errors ('play of chance'). ### Main Results Six randomised clinical trials with 581 participants with chronic hepatitis C were included. All trials had high risk of bias. The included trials compared amantadine versus other antiviral drugs: ribavirin, mycophenolate mofetil, interferon-alpha, or interferon-gamma. Standard antiviral therapy (interferon-alpha, interferon-alpha plus ribavirin, or peg interferon alpha) was administered equally to the intervention and the control groups in five trials, depending on when the trial was conducted. Four trials compared amantadine versus ribavirin. There were no deaths or liver-related morbidity in the two intervention groups (0/216 (0%) versus 0/211 (0%); 4 trials; very low quality of the evidence). The lower estimated risk for (serious) adverse events leading to treatment discontinuation with amantadine was imprecise (RR 0.56, 95% CI 0.27 to 1.16; based on 10/216 (5%) versus 18/211 (9%) participants in 4 trials; very low quality of the evidence). There were more participants with failure of sustained virological response in the amantadine group than in the ribavirin group (206/216 (96%) versus 176/211 (84%); RR 1.14, 95% CI 1.07 to 1.22, 4 trials; low quality of the evidence). amantadine versus ribavirin more often failed to achieve end-of follow-up biochemical response (41/46 (89%) versus 31/46 (67%); RR 1.31, 95% CI 1.05 to 1.63; 2 trials; very low quality of the evidence). One trial compared amantadine versus mycophenolate mofetil. There were no significant differences between the two treatment groups , except that amantadine was inferior to mycophenolate mofetil regarding the outcome failure to achieve end-of treatment virological response ( low quality of evidence ) . One trial each compared amantadine versus interferon-alpha or interferon-gamma. Both comparisons showed no significant differences in the treatment outcomes (very low quality of the evidence). The observed effects could be due to real effects, systematic errors (bias), or random errors (play of chance). This possible influence on the observed effect by play of chance is due to the fact that trial sequential analyses could not confirm our findings. We were not able to perform meta-analyses on failure of histological improvement and quality of life due to lack of valid data in all trial comparisons. ### Authors Conclusions This systematic review has identified evidence of very low quality for the key outcomes of all-cause mortality or liver-related morbidity and adverse events in people with chronic hepatitis C when treated with amantadine compared with ribavirin, mycophenolate, interferon-alpha, or interferon-gamma. The timeframe for measuring the composite outcome was insufficient in the included trials. There was low quality evidence that amantadine led to more participants who failed to achieve sustained virological response compared with ribavirin. This observation may be real or caused by systematic errors (bias), but it does not seem to be caused by random error (play of chance). Due to the low quality of the evidence, we are unable to determine definitively whether amantadine is less effective than other antivirals in patients with chronic hepatitis C. As it appears less likely that future trials assessing amantadine or potentially other aminoadamantanes for patients with chronic hepatitis C would show strong benefits, it is probably better to focus on the assessments of other direct acting antiviral drugs. We found no evidence assessing other aminoadamantanes in randomised clinical trials in order to recommend or refute their use.


sunitinib

pazopanib

Pazopanib has equivalent anti-tumor effectiveness and lower Total costs than Sunitinib for treating metastatic or advanced renal cell carcinoma: a meta-analysis. sunitinib and pazopanib are extensively used as first-line treatment of metastatic renal cell carcinoma (mRCC). We performed this meta-analysis to assess the anti-tumor effectiveness, toxicity, and total costs of the two drugs among patients with mRCC/advanced RCC (aRCC). ### Materials And Methods PubMed, ScienceDirect, Scopus, Web of Science, Ovid MEDLINE, the Cochrane Library, Embase, and Google Scholar were searched to obtain eligible articles. The endpoints included progression-free survival (PFS), overall survival (OS), adverse effects (AEs), and per-patient-per-month (PPPM) costs. ### results We included 14 medium- to high-quality studies. Both drugs were valid for mRCC/aRCC, with equivalent PFS (hazard ratio (HR) =1.06, 95% confidence interval [CI]: 0.98-1.15, P = 0.13), OS (HR = 0.92, 95% CI: 0.79-1.07, P = 0.29), objective response rate (ORR, risk ratio (RR) =1.03, 95% CI: 0.93-1.13, p = 0.58), and disease control rate (DCR, RR = 1.03, 95% CI: 0.94-1.22, P = 0.54). sunitinib had more dosage reductions and higher PPPM (weighted mean difference = - 1.50 thousand US dollars, 95% CI: - 2.27 to - 0.72, P = 0.0002). Furthermore , more incidences of severe fatigue , thrombocytopenia , and neutropenia were recorded for sunitinib , but pazopanib had more liver toxicity . In subgroup analysis, studies from the US reported longer OS (HR = 0.86, 95% CI: 0.77-0.95, P = 0.004) and higher ORR (RR = 1.24, 95% CI: 1.03-1.51, P = 0.03). ### conclusions pazopanib provides equivalent anti-tumor effectiveness and lower PPPM as compared with sunitinib for mRCC/aRCC. Great care should be given to pazopanib-treated patients with abnormal liver function. Nevertheless, more large-scale, high-quality studies are required.


Streptomycin

gentamicin

netilmicin

Activity of aminoglycosides against phagocytosed bacteria. The intracellular activity of streptomycin, gentamicin, and netilmicin on Escherichia coli phagocytosed by murine peritoneal macrophages was studied using a sensitive and standardized method. Intracellular activity of streptomycin and gentamicin at therapeutic concentrations was seen after 1 h of incubation of antibiotics with macrophages containing phagocytosed bacteria, whilst for netilmicin a significant intracellular activity was observed only after 3 h exposure. The activity of these antibiotics against intraphagocytic bacteria was significantly lower than that observed against extracellular bacteria. Sub-inhibitory concentrations of streptomycin were active against intracellular E. coli. streptomycin was also active for a phagocytosed streptomycin-resistant strain of E. coli, but this activity was eliminated when the O2-dependent killing mechanisms of macrophages were inhibited by sodium fluoride. The data demonstrate that aminoglycosides may exert a dose-dependent intraphagocytic activity against E. coli that correlates with the time of incubation of the antibiotics with infected macrophages. Streptomycin appears to be the most effective agent followed by gentamicin and the least active was netilmicin . In the case of streptomycin, the intraphagocytic activity seems to be due, at least in part, to the stimulation of O2-dependent cellular microbactericidal mechanisms.


clomipramine

methylphenidate

buspirone

naltrexone

Comprehensive management of trichotillomania in a young autistic girl. The coexistence of trichotillomania and autistic disorder has rarely been reported in psychiatric literature. The current study describes successful treatment of trichotillomania in a young autistic girl, using combined clomipramine and behavioral therapy. Neither behavioral therapy , clomipramine , methylphenidate , buspirone , nor naltrexone was effective in monotherapeutic trials . We postulate a synergistic effect of combined treatment with clomipramine and behavioral therapy, suggesting that both pharmacological and behavioral treatment of hair pulling may be necessary for many patients. This model is consistent with the extant literature and suggests that future clinical trials of clomipramine for trichotillomania, in both developmentally disabled and normal subjects, must evaluate this multimodal approach.


granisetron

mosapride

Exploration of Antiemetics for Osteoporosis Therapy-Induced Nausea and Vomiting Using PET Molecular Imaging Analysis to Gastrointestinal Pharmacokinetics. To select appropriate antiemetics relieving teriparatide-induced nausea and vomiting during osteoporosis treatment using PET molecular imaging and pharmacokinetic analysis. ### methods Rats were pretreated with subcutaneous teriparatide, followed by oral administration of antiemetics with different pharmacological effects. The pharmacokinetics of antiemetics were assessed by oral administration of 2-deoxy-2-[(18)F]fluoro-D-glucose ([(18)F]FDG) under free moving conditions in vivo. The effect of teriparatide on the permeability of Caco-2 cell membranes to [(18)F]FDG was assessed in vitro. The effects of antiemetics on teriparatide-induced suppression of gastrointestinal motility in vivo was assayed by positron emission tomography (PET) using orally administered [(18)F]FDG. ### results Teriparatide delayed the time-radioactivity profile of [(18)F]FDG in blood and significantly reduced its absorption rate constant (k a ), determined from non-compartmental analysis, to 60% of control. In contrast, co-administration of granisetron or mosapride restored the time-radioactivity profile and k a of [(18)F]FDG to control levels. Teriparatide had no effect on Caco-2 membrane permeability to [(18)F]FDG. Pharmacokinetic PET imaging data analysis quantitatively showed the pharmacological effects of teriparatide-induced suppression of upper gastrointestinal motility and its restoration by granisetron and mosapride . ### conclusions Teriparatide-induced abdominal discomfort might be attributed to GI motility, and PET imaging analysis is a useful tool to for the selection of appropriate antiemetics.


palbociclib

ribociclib

letrozole

anastrozole

fulvestrant

First clinical experience with CDK4/6 inhibitors in breast cancer therapy. For hormone receptor-positive, HER2-negative breast cancer patients with metastatic or advanced disease, therapy with CDK4/6 inhibitors in addition to aromatase inhibitors (AIs) or to the estrogen receptor (ER) downregulator fulvestrant has resulted in an additional therapy option and a longer progression-free survival. In the Gynecologic-Oncology Clinic, Diakonie-Klinikum Schwäbisch Hall, we followed and registered our initial clinical experience with CDK4/6 inhibitors, following the side effects and tumor response over two years since they were officially approved for general use in Germany. Differences were observed when palbociclib or ribociclib was used in combination with letrozole or anastrozole or fulvestrant . The dynamic side effects and tumor response under therapy with palbociclib or ribociclib were found to be comparable with the main reported data in the official drug information. The CDK4/6 inhibitors have an important and promising role in the therapy of breast cancer patients. Patient age and therapy duration do not influence the use of palbociclib or ribociclib, although it may be important which AI is used in combination with palbociclib.


cyclosporine

lovastatin

Rhabdomyolysis and renal injury with lovastatin use. Report of two cases in cardiac transplant recipients. Hyperlipidemia, particularly hypercholesterolemia, occurs in cardiac transplant recipients both as a preexisting condition and as a consequence of immunosuppressive therapy. lovastatin (Mevacor) has emerged as an agent that may effectively manage this condition. Few serious side effects of this drug have been observed. We describe two cardiac transplant recipients treated with lovastatin in conjunction with their other medications, including cyclosporine, who developed acute renal failure and rhabdomyolysis. Resolution of muscle damage followed discontinuation of cyclosporine and lovastatin therapy . We postulate that hepatic dysfunction secondary to cyclosporine predisposed these patients to lovastatin-induced muscle damage. Use of this drug in cardiac and other organ transplant recipients should be accompanied by close surveillance of creatine kinase, hepatic transaminases, and cyclosporine levels.

Effect of 1-aminoadamantanes on the MAO activity in brain, liver, and kidney of the rat.  In order to elucidate the possible interference of the antiparkinson drug 1-aminoadamantane ( D-1 , PK Merz ) and the antispastic compound 1,3-dimethyl-5-aminoadamantane ( DMAA , D-145 , memantine , Memantine ) on neurotransmitter metabolism , the effect of D-1 and its C-alkyl derivatives memantine , 1-amino-3,5,7-trimethyladamantane ( D-191 ) , and 1-amino-3-(n)-butyladamantane ( D-178 ) on MAO activity in brain , liver , and kidney of the rat was investigated . A radioisotope method using [14C]5-hydroxytryptamine as substrate was used. The highest MAO activity was found in liver followed by brain and kidney (Vmax: 137, 64, and 26 nmol/mg protein X h, respectively). The Km values did not differ significantly for the three tissues (liver: 107 mumol/l; brain: 96 mumol/l; kidney: 86 mumol/l). The MAO activity in liver, brain and kidney was noncompetitively inhibited by all 1-aminoadamantanes studied, each derivative, respectively, showing in all three tissues about the same percentage inhibition. The inhibitory activity was found to be increased with the degree of C-alkylation: D-1 (Ki approximately 1 mmol/l) less than D-145 (Ki approximately 0.1 mmol/l) less than D-191 (Ki approximately 0.07 mmol/l) less than D 178 (Ki approximately 0.02 mmol/l).


gemcitabine

doxorubicin

docetaxel

Primary chemotherapy with gemcitabine , liposomal doxorubicin and docetaxel in patients with locally advanced breast cancer : results of a phase I trial . The primary objective was to determine the optimal doses for gemcitabine (prolonged infusion), liposomal doxorubicin (Myocet) and docetaxel as primary (neoadjuvant) chemotherapy for locally advanced breast cancer. Secondary objectives included evaluation of the safety and efficacy of the regimen. Patients (n=19) with histologically confirmed stage II or III breast cancer were treated with liposomal doxorubicin (50-60 mg/m2) and docetaxel (60-75 mg/m2) on day 1, and gemcitabine as 4-h infusion (350-400 mg/m2) on day 4. Treatment was repeated every 3 weeks for a maximum of 6 cycles. The maximum tolerated doses were gemcitabine 350 mg/m2, liposomal doxorubicin 60 mg/m2 and docetaxel 75 mg/m2. Dose-limiting toxicities were stomatitis, diarrhea and infection. The predominant hematologic toxicity was mild-to-moderate myelosuppression with grade 3/4 neutropenia in 20% of cycles. Non-hematologic toxicity was generally mild, with no grade 4 toxicities being observed. Predominant non-hematologic toxicity was stomatitis, which occurred in 95% of patients. Grade 3 toxicities were reported for stomatitis, nausea, diarrhea, infection and constipation. No cases of cardiac, renal, pulmonary or neurotoxicity were observed. The clinical response rate was 83% and histologically confirmed, clinically complete remissions occurred in two patients (11%). We conclude that the combination of gemcitabine (prolonged infusion), liposomal doxorubicin and docetaxel is safe and highly effective in patients with locally advanced breast cancer as defined by maximum tolerated doses. The evaluated schedule is suitable for phase II studies.


dexamethasone

leptin

Effect of one morning meal and a bolus of dexamethasone on 24-hour variation of serum leptin levels in humans. We have previously shown that morning administration of dexamethasone in combination with food induces a doubling of serum leptin levels starting at 7 hours after dexamethasone administration, with a maximum effect at 10 hours, the latest time point that we have studied. However, dexamethasone given in the absence of food had no effect on serum leptin at 10 hours. The present experiment was undertaken to determine the duration of the effect of dexamethasone on 24-hour serum leptin under fasted and fed conditions in humans. ### Research Methods And Procedures Six healthy non-obese male volunteers were studied under the following four conditions: 1) dexamethasone (2 mg intravenously, given at 0900 hours) with fasting; 2) dexamethasone with food (1,700 kcal, 55% carbohydrate, 15% protein, and 30% fat, given in one meal 2 hours after dexamethasone administration at 1100 hours); 3) saline with food (same meal); 4) saline with fasting. Serum leptin, glucose, insulin, and cortisol were monitored every 30 minutes for 24 hours. ### results 1) Under the fasting condition, dexamethasone increased leptin nocturnal secretion between 2100 and 2400 hours. 2) A single meal (1,700 kcal) at 1100 hours increased nocturnal leptin secretion when compared with the fasting condition. The peak increase of leptin was 123% over baseline between 2100 and 2400 hours, 10 to 14 hours after the meal. 3) In the fed + dexamethasone condition, leptin levels increased from baseline starting 8 hours after dexamethasone injection, reached a maximum increase of 260% between 2100 and 2400 hours, then decreased thereafter, remaining elevated compared to baseline for 16 hours. There was a correlation between 24-hour leptin secretion and insulin secretion after a single morning meal. ### discussion A single bolus of dexamethasone , given before a single large meal , produces a delayed ( 6-hour ) but long-lasting increase in serum leptin ( over 16 hours ) . Under fasted conditions, dexamethasone does not increase daytime leptin but does increase leptin during the night.


aripiprazole

valproic

haloperidol

valproic

Combination treatment with aripiprazole and valproic acid for acute mania: an 8-week, single-blind, randomized controlled trial. Despite the fact that combination treatment for patients with acute bipolar is prevalent in clinical practice, the outcomes of adjunct treatment with aripiprazole and a mood stabilizer have rarely been reported. The aim of this single-blind , randomized , controlled trial was to investigate treatment efficacy and safety of aripiprazole as an adjunct to valproic acid ( Ari+Val ) , compared with haloperidol plus valproic acid ( Hal+Val ) , in acute manic patients . ### methods Treatment efficacy was prospectively assessed for 8 weeks in 42 patients with acute mania using the Young Mania Rating Scale and the Clinical Global Impression-Severity of illness scale. Emergent adverse events were assessed by the Drug-Induced Extrapyramidal Symptoms Scale and the Liverpool University Neuroleptic Side Effect Rating Scale. ### results Both Ari+Val and Hal+Val produced a high rate of response (85.7% and 92.9%, respectively) and remission (82.1% and 85.7%, respectively) after the 8-week trial. Changes in the Young Mania Rating Scale and the Clinical Global Impression-Severity of illness scale over the study period and time to remission and response were not significantly different between the 2 groups. Patients treated with Ari+Val showed significantly fewer extrapyramidal adverse events than those treated with Hal+Val (t = -2.048, F = 40, P = 0.048). However, significant weight gain was more prevalent in the Ari+Val group than the Hal+Val group (t = 2.055, F = 40, P = 0.046). ### conclusions Our findings suggest that both combination strategies with Ari+Val and Hal+Val are beneficial for acute manic episode. Although patients receiving Ari+Val showed fewer extrapyramidal symptoms than those taking Hal+Val, careful consideration of adverse events such as weight gain and sedation is warranted.


ketorolac

propofol

Ketorolac and propofol administration for prevention of nausea and vomiting in patients undergoing minor gynecologic surgery. This clinical review explores the efficacy of the nonsteroidal antiinflammatory agent, ketorolac tromethamine, added to an anesthetic regimen utilizing intravenous propofol. Both agents have been shown to reduce the incidence of nausea and vomiting postoperatively when administered to patients undergoing minor gynecologic surgery. Because the incidence of nausea and vomiting is significantly reduced when ketorolac is used in place of opioids to attenuate postoperative pain , it would appear to be an appropriate choice of agent to use following propofol anesthesia . The use of this combination of drugs may not only reduce the incidence of postoperative nausea and vomiting in patients undergoing minor gynecologic surgery, but could reduce the duration of hospitalization and enhance recovery from anesthesia.


vandetanib

bicalutamide

bicalutamide

A randomized phase II efficacy and safety study of vandetanib (ZD6474) in combination with bicalutamide versus bicalutamide alone in patients with chemotherapy naïve castration-resistant prostate cancer. To investigate the efficacy and safety of combining vandetanib, an orally available multi-targeted tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2) and epidermal growth factor receptor (EGFR), with bicalutamide in patients with metastatic castration-resistant prostate cancer (mCRPC). ### methods This was an open-label, randomized phase II multi-center study. Eligible patients had rising PSA on androgen deprivation therapy, minimal symptoms and were chemotherapy-naïve. Protocol therapy was either vandetanib 300 mg oral daily plus bicalutamide 50 mg oral daily (Arm A) or bicalutamide 50 mg oral daily alone (Arm B) with cross-over to vandetanib monotherapy at progression. The primary endpoint was PSA response (≥ 50 % decline from baseline). ### results Thirty-nine patients were recruited, 19 in Arm A and 20 in Arm B. PSA response was comparable in Arm A and Arm B (18 vs. 19 %). Time to PSA progression was 3.16 months (95 % confidence interval (CI): 1.09, not reached (NR)) for Arm A and 3.09 months (95 % CI: 1.22, NR) for Arm B. Treatment discontinuation due to adverse events was more common in Arm A compared to Arm B (42 vs. 5 %; p = 0.019). Treatment with vandetanib was associated with a reduction in soluble VEGFR-2 levels after two cycles but an increase in plasma VEGF levels. ### conclusion The combination of vandetanib and bicalutamide was associated with considerable toxicity and did not have superior efficacy over bicalutamide alone . Further evaluation of this combination is not warranted in mCRPC.


Aspirin

Atenolol

Metformin

Aspirin and atenolol enhance metformin activity against breast cancer by targeting both neoplastic and microenvironment cells. metformin can induce breast cancer (BC) cell apoptosis and reduce BC local and metastatic growth in preclinical models. Since metformin is frequently used along with aspirin or beta-blockers, we investigated the effect of metformin, aspirin and the beta-blocker atenolol in several BC models. In vitro, aspirin synergized with metformin in inducing apoptosis of triple negative and endocrine-sensitive BC cells, and in activating AMPK in BC and in white adipose tissue (WAT) progenitors known to cooperate to BC progression. Both aspirin and atenolol added to the inhibitory effect of metformin against complex I of the respiratory chain. In both immune-deficient and immune-competent preclinical models, atenolol increased metformin activity against angiogenesis, local and metastatic growth of HER2+ and triple negative BC. aspirin increased the activity of metformin only in immune-competent HER2+ BC models. Both aspirin and atenolol, when added to metformin, significantly reduced the endothelial cell component of tumor vessels, whereas pericytes were reduced by the addition of atenolol but not by the addition of aspirin. Our data indicate that the addition of Aspirin or of Atenolol to Metformin might be beneficial for BC control , and that this activity is likely due to effects on both BC and microenvironment cells .


vorinostat

oxaliplatin

Vorinostat enhances the anticancer effect of oxaliplatin on hepatocellular carcinoma cells. oxaliplatin-based systemic chemotherapy has been proposed to have efficacy in hepatocellular carcinoma (HCC). We investigated the combination of vorinostat and oxaliplatin for possible synergism in HCC cells. SMMC7721, BEL7402, and HepG2 cells were treated with vorinostat and oxaliplatin. Cytotoxicity assay, tumorigenicity assay in vitro, cell cycle analysis, apoptosis analysis, western blot analysis, animal model study, immunohistochemistry, and quantitative PCR were performed. We found that vorinostat and oxaliplatin inhibited the proliferation of SMMC7721, BEL7402, and HepG2 cells. The combination index (CI) values were all <1, and the dose-reduction index values were all greater than 1 in the three cell lines, indicating a synergistic effect of combination of the two agents. Coadministration of vorinostat and oxaliplatin induced G2/M phase arrest , triggered caspase-dependent apoptosis , and decreased tumorigenicity both in vitro and in vivo . vorinostat suppressed the expression of BRCA1 induced by oxaliplatin. In conclusion, cotreatment with vorinostat and oxaliplatin exhibited synergism in HCC cells. The combination inhibited cell proliferation and tumorigenicity both in vitro and in vivo through induction of cell cycle arrest and apoptosis. Our results predict that a combination of vorinostat and oxaliplatin may be useful in the treatment of advanced HCC.


gentamicin

doxycycline

Randomized open trial of gentamicin and doxycycline for eradication of Bartonella quintana from blood in patients with chronic bacteremia . Chronic Bartonella quintana bacteremia is known to occur in homeless people exposed to lice. We present here the results of an open randomized trial performed to evaluate the efficacy of doxycycline in combination with gentamicin in the eradication of B. quintana bacteremia. From 1 January 2001 to 1 April 2002, homeless people with blood cultures positive for B. quintana were randomized to receive either no treatment (untreated controls) or a combination of gentamicin (3 mg/kg of body weight/day intravenously for 14 days) and doxycycline (200 mg/day orally for 28 days). Patients were evaluated from the results of blood cultures performed between day 28 (the end of treatment) and day 90 postinclusion. Intention-to-treat analysis of 20 included patients showed eradication of bacteremia in 7 out of 9 treated patients versus 2 out of 11 untreated controls (P = 0.01). In the per-protocol analysis, eradication was obtained for 7 out of 7 treated patients versus 2 out of 9 untreated controls (P = 0.003). This study demonstrates the efficiency of the combination of doxycycline and gentamicin in eradicating B. quintana bacteremia.


aspirin

clopidogrel

[TREATMENT WITH DUAL ANTIPLATELET THERAPY FOR SECONDARY PREVENTION OF STROKE - PROS AND CONS].  The role of dual antiplatelet therapy combining aspirin and clopidogrel , is controversial . There are two settings in which such treatment might be considered: (a) patients presenting with a first ischemic event at high risk for a recurrence; and (b) patients who experience a second ischemic event while being treated with aspirin or clopidogrel monotherapy. In this paper we review the literature dealing with secondary prevention of ischemic stroke, with an emphasis on dual antiplatelet therapy. We examine international guidelines and present a case study which illustrates the application of this information.


daunorubicin

imatinib

cytarabine

The addition of daunorubicin to imatinib mesylate in combination with cytarabine improves the response rate and the survival of patients with myeloid blast crisis chronic myelogenous leukemia (AFR01 study). The median survival of patients with chronic myelogenous leukemia in myeloid blast crisis (MBC-CML) is poor even for patients treated with tyrosine kinase inhibitors (TKIs). ### Design And Methods We conducted a dose-escalating study of daunorubicin combined to fixed doses of IM ( imatinib mesylate , 600 mg/d ) and cytarabine ( 200 mg/d for 7 days ) , followed by hematopoietic stem cell transplantation or maintenance therapy with single-agent IM in patients with MBC-CML at onset or after failure of therapy excluding TKIs . ### results Thirty-six patients were evaluated. Median follow-up is 6.1 years. daunorubicin was escaladed up to 45 mg/m(2)/d 3 days. Twenty eight patients (77.7%) had hematologic response including 20 patients (55.5%) in complete hematologic response (CHR). Patients who received daunorubicin at 30-45 mg/m(2)/d had higher CHR rates compared to other patients. Median overall survival was 16 months. Overall survival in patients with hematological response was 35.4 months. Better results were observed in patients diagnosed with MBC-CML at onset. ### conclusions The combination of IM with a standard "3+7" regiment was well tolerated and provided a high response rate. More than 55% of the patients achieved CHR and hematopoietic stem cell transplantation (SCT) was feasible in half of the cases. This trial was registered at www.clinicaltrials.gov as # NCT00219765.


cyclophosphamide

adriamycin

prednisolone

tamoxifen

[ Combination chemo-endocrine therapy of metastatic and stage IV breast cancer with cyclophosphamide , adriamycin , prednisolone and tamoxifen (CAPT)--with special reference to management of brain and liver metastasis ] . Sixty-three evaluable patients with metastatic and stage IV breast cancer who had not previously undergone chemo-endocrine therapy were treated with a combination chemoendocrine therapy regimen consisting of cyclophosphamide 100 mg p.o. every day, adriamycin 10 mg i.v. on day 1 to 5, prednisolone 10 mg or 20 mg (20 mg was given on day 1 to 5) p.o. every day, and tamoxifen 20 mg p.o. every day. Adriamycin on day 1 to 5 was repeated three times every two weeks. After a total dose of 150 mg of adriamycin, the patients were changed to maintenance therapy consisting of cyclophosphamide 100 mg p.o., prednisolone 10 mg p.o. and tamoxifen 20 mg p.o. every day. After 72 months of the treatment there were 61 patients good for evaluation, 13 patients achieved a complete response (21.3%) with a median survival of 30.5 months and 18 patients had a partial response (29.5%) with a median survival of 21.0 months, and 30 patients failed to respond (49.2%) with a median survival of 8.5 months. There was a significant difference in survival time between responders (CR + PR) and non-responders (NC + PD) (p less than 0.001). Responses by site were seen in lung 10/18 (55.6%), liver 3/6 (50.0%), brain 2/4 (50.0%), bone 6/17 (35.3%) and soft tissue 14/24 (56.3%). A Satisfactory response for brain and liver metastasis, which are usually viewed as a sign of grim prognosis, was obtained similar to other sites of metastasis. Retreatment with CAPT, which was attempted in patients with secondary brain metastasis who responded to CAPT for initial brain metastasis, was uniformly effective. High ration of androgen to corticosteroid, positive estrogen receptors, long disease-free survival (over two years), premenopausal, high Broca' index (above 110) resulted from the chemo-endocrine therapy regimen CAPT. Toxicity was minimal and consisted of nausea, vomiting, alopecia and leucopenia.


epinephrine

propranolol

Alpha-adrenergic agonists stimulate neonatal glucose production less than beta-adrenergic agonists in the lamb. epinephrine, a catecholamine with both alpha (alpha)- and beta (beta)-adrenergic agonist effects, may produce clinical hyperglycemia in the adult by increasing glucose production and decreasing glucose clearance. However, the relative contribution of alpha v beta adrenergic agonists in control of neonatal glucose kinetics has not been defined. Twenty-three term lambs (weighing 4.4 +/- 0.2 kg, mean +/- SEM, and aged 3.8 +/- 0.4 days) were infused with 0.9% NaCl at 0.6 mL.kg-1 min-1 + 100 microCi/kg D[6-3H]-glucose by prime plus constant infusion for 210 minutes. Ra ( rate of production ) was measured during infusion of variable doses of epinephrine with or without variable doses of propranolol , a competitive beta-adrenergic antagonist to isolate the alpha-adrenergic agonist effects . All basal kinetic data were comparable. Under conditions of epinephrine infusion, the plasma glucose concentration increased from 95 +/- 10 mg/dL to 129 +/- 18 mg/dL (50 ng.kg-1 min-1 epinephrine; P less than .0001) and from 85 +/- 6 mg/dL to 253 +/- 8 mg/dL (500 ng.kg-1 min-1 epinephrine; P less than .00001) compared with controls (96 +/- 7 mg/dL to 95 +/- 8 mg/dL). When epinephrine and propranolol were infused simultaneously, plasma glucose concentration increased from 95 +/- 10 mg/dL to 122 +/- 12 mg/dL (50 ng.kg-1 min-1 epinephrine + 1.1 micrograms.kg-1 min-1; P less than .0001) and from 78 +/- 9 mg/dL to 134 +/- 12 mg/dL (500 ng.kg-1 min-1 epinephrine + 11 micrograms.kg-1 min-1; P less than .0001) compared with controls (no epinephrine, no propranolol).(ABSTRACT TRUNCATED AT 250 WORDS)


doxorubicin

epirubicin

Comparisons of Cardiotoxicity and Efficacy of Anthracycline-Based Therapies in Breast Cancer: A Network Meta-Analysis of Randomized Clinical Trials. The effects of anthracycline-based chemical therapies on breast cancer are controversial and inconclusive. We undertook a network meta-analysis to assess the cardiotoxicity and effects of anthracycline therapies in breast cancer. The PubMed, Embase, and Cochrane databases up to August 2018 were reviewed. We identified 19 randomized clinical trials including 3,484 patients with breast cancer which assessed both cardiotoxicity and the effects of anthracycline-based therapies. Eligible studies included the following five treatment strategies: doxorubicin, epirubicin, liposomal doxorubicin (LD), doxorubicin + dexrazoxane (DD), and epirubicin + dexrazoxane (ED). In a direct meta-analysis, epirubicin, LD, DD, and ED had significantly superior cardioprotective effects compared with doxorubicin with odds ratios and 95% CIs of 1.64 (1.04, 2.57), 3.75 (2.46, 5.70), 2.88 (1.93, 4.29), and 3.66 (1.09, 12.33), respectively. doxorubicin showed no significant difference of response rate compared with epirubicin or LD or DD, respectively. In a network meta-analysis, the ranking order of cardiotoxicity was doxorubicin (worst), epirubicin, DD, LD, and ED (best). The ranking order of the response rate was LD ( best ) , doxorubicin , epirubicin , ED , and DD ( worst ) . The most favorable balance between benefit and risk was shown for ED (best) followed by LD, DD, epirubicin, and doxorubicin. In conclusion, LD or ED is the suitable anthracycline treatment for breast cancer in consideration of both cardiotoxicity and efficacy.


physostigmine

scopolamine

mecamylamine

Role of acetylcholine transmission in nucleus accumbens and ventral tegmental area in heroin-seeking induced by conditioned cues. The involvement of cholinergic transmission in heroin self-administration and the reinstatement of heroin-seeking was examined in rats trained to nose-poke for i.v. heroin. Systemic treatment with physostigmine , an inhibitor of acetylcholinesterase , modestly reduced the acquisition and rate of heroin self-administration , and this suppression of heroin intake was reversed by pretreatment with scopolamine but not by mecamylamine . Following 10-14 days of self-administration, rats were left in the home environment for 14 days. Subsequently, rats were evaluated for extinction of nose-pokes during the first hour after being returned to the self-administration apparatus. One hour later a conditioned stimulus (house light, light in the nose-poke hole, sound of the infusion pump) was presented to initiate cue-induced reinstatement. Physostigmine produced a dose-dependent inhibition of cue-induced reinstatement, but only the dose of 0.5 mg/kg significantly decreased nose-poke responding in the extinction test. Chronic treatment with physostigmine (0.1 mg/kg) did not impair performance during acquisition of heroin self-administration. However, during a subsequent reinstatement test conducted in the absence of physostigmine pretreatment, heroin seeking was significantly below that of rats chronically pretreated with saline. To evaluate brain regions mediating the effects of systemic drug treatment on reinstatement, physostigmine was microinjected into the nucleus accumbens (NAc) or ventral tegmental area (VTA). Microinjection of physostigmine into the NAc prior to presenting conditioned cues inhibited the reinstatement of heroin-seeking, without affecting extinction responding. In contrast, microinjection of physostigmine into the VTA augmented the reinstatement induced by conditioned cues and extinction responding. Inactivation of either NAc or VTA by microinjecting tetrodotoxin blocked both extinction responding and cue-induced reinstatement. These data demonstrate that cholinergic transmission influences heroin self-administration and reinstatement. Moreover, cue-induced reinstatement was inhibited by physostigmine in the NAc and potentiated by cholinergic stimulation in the VTA.


lenvatinib

sorafenib

Hepatocellular Carcinoma with Portal Vein Tumor Involvement: Best Management Strategies. Portal vein tumor thrombosis (PVTT) commonly occurs in patients with hepatocellular carcinoma (HCC). Patients with PVTT usually have an aggressive disease course, decreased liver function reserve, limited treatment options, higher recurrence rates after treatment, and, therefore, worse overall survival. Among untreated HCC patients with PVTT, the median overall survival has been reported as low as 2 to 4 months. Historically, many aspects of PVTT have impacted the theoretical and practical safety and efficacy of treatment, for example, disordered blood flow and associated impairment of liver function, heat-sink effects of blood flow in the area of the PVTT, and risk of recurrence due to tumor location in the blood vessel. The current Barcelona Clinic Liver Cancer staging system categorizes HCC patients with PVTT as advanced stage, for which the standard of care is targeted therapy with sorafenib. However, sorafenib is associated with only marginal benefits among patients with PVTT. First-line lenvatinib , which was shown to be noninferior to sorafenib , excluded patients with main portal trunk invasion . regorafenib and nivolumab, an immune-based therapy, were recently approved in the United States for second-line therapy after sorafenib. Preliminary results for cabozantinib suggest a benefit in the second-/third-line after sorafenib failure. In addition, rapid advances in many fields (surgery, interventional radiology, nuclear medicine, and immunotherapy) have increased the potential treatment options for the management of this complex disease entity. A large portion of the emerging evidence focuses on the broader category of advanced HCC of which PVTT is a subgroup. While many of these studies show promising results, the efficacy among PVTT patients requires validation in prospective studies. Real-world data may help fill the evidence gap for patients not eligible for clinical trials due to common hepatic function requirements. The variety of new treatment advances for the heterogeneous and complex disease entity of HCC with PVTT means that personalized, multidisciplinary management may be necessary to achieve optimal outcomes. In this narrative review, we summarize the evolving management strategies for patients with HCC and PVTT.


atezolizumab

docetaxel

Fast progression in non-small cell lung cancer: results from the randomized phase III OAK study evaluating second-line atezolizumab versus docetaxel. Treatment-induced accelerated tumor growth is a progression pattern reported with immune checkpoint inhibitors that has never been evaluated in randomized phase III studies because it requires two pretreatment scans. This study aimed to develop clinically relevant and applicable criteria for fast progression (FP), incorporating tumor growth kinetics and early death from disease progression to analyze data from the randomized phase III OAK study. ### methods The OAK study evaluated the efficacy and safety of atezolizumab versus docetaxel as second-line or third-line treatment for stage IIIb/IV non-small cell lung cancer . FP rates and associated baseline factors were analyzed. FP was defined as either a ≥50% increase in the sum of largest diameters (SLDs) within 6 weeks of treatment initiation or death due to cancer progression within 12 weeks (absent post-baseline scan). ### results Forty-two of 421 patients (10%) receiving atezolizumab and 37 of 402 (9%) receiving docetaxel had FP. Twenty patients with FP (48%) receiving atezolizumab versus 12 (30%) receiving docetaxel had a ≥50% SLD increase within 6 weeks. FP was significantly associated with an ECOG (Eastern Cooperative Oncology Group) performance status of 1 (vs 0), ≥3 metastatic sites at baseline, and failure of preceding first-line treatment within 6 months, but not with epidermal growth factor receptor mutation, programmed cell death 1 ligand 1 or tumor mutational burden. Overall survival in patients with FP and a ≥50% SLD increase at week 6 was similar with atezolizumab and docetaxel (unstratified HR 0.89 (95% CI 0.41 to 1.92)). ### conclusions FP rates were similar with atezolizumab and docetaxel in the OAK study, suggesting that FP may not be unique to checkpoint inhibitors, although the underlying mechanisms may differ from those of chemotherapy. Applying the FP criteria to other phase III checkpoint inhibitor trials may further elucidate the risk factors for FP. ### Trial Registration Number NCT02008227.


bleomycin

triamcinolone

Results of a combination of bleomycin and triamcinolone acetonide in the treatment of keloids and hypertrophic scars. While treatment of keloids and hypertrophic scars normally shows modest results, we found that treatment with bleomycin was more promising. The present study was divided into two parts. In the first part the aim was to show the results using a combination of bleomycin and triamcinolone acetonide per cm2 (BTA). In the second part the objective was to determine the response to both drugs in large keloids that were divided into 1 cm2 squares, treating each square with the dose previously used. In the first part of the study, the clinical response of 37 keloids ranging from 0.3 to 1.8 cm2 treated with BTA were followed up over a period of 1- 2 years. 0.375 IU bleomycin and 4 mg triamcinolone acetonide were injected every 3 months. In the second part of the study we reviewed the clinical response in six patients with large keloids. The monthly dose administered never exceeded 3 IU of bleomycin. The first study showed 36 keloids (97.29%) softening after the first dose. In the second study, 5 showed different responses (the response was complete in the four smaller keloids). The largest keloid needed 9 doses to achieve an improvement of 70%. In conclusion , combined treatment with 0.375 IU of bleomycin and 4 mg of triamcinolone acetonide to 1 cm2 was considered to be an acceptable procedure for the treatment of keloids . The best results were obtained in keloids over 1 cm2 or when divided into 1 cm2 square areas. Larger series need to be performed in order to confirm these results..


levetiracetam

topiramate

lacosamide

topiramate

Absence status induced by lacosamide adjunctive therapy. Since lacosamide was approved as an adjuvant agent for the treatment of medically refractory focal epilepsy over ten years ago, it is becoming more widely used for the treatment of idiopathic (genetic) generalized epilepsies. Several studies have demonstrated efficacy in reducing primary generalized tonic-clonic seizures (GTCS), but efficacy is less well-characterized for myoclonic and absence seizures. A 29-year-old man with juvenile myoclonic epilepsy and medically refractory GTCS on a combination of levetiracetam and topiramate was started on lacosamide adjunctive therapy with the plan to replace topiramate . While his GTCS became controlled, he was witnessed to have confusional episodes, with waxing and waning responsiveness, lasting a few days, several times a month. After eight months of adjunctive lacosamide therapy, he was admitted to the epilepsy monitoring unit, where paroxysms of generalized spike-and-wave complexes, lasting for 30-90 minutes, were recorded, interrupted only by sleep. During these periods, he demonstrated psychomotor slowing and disorientation on examination. The absence status was successfully broken by lorazepam, and lacosamide was discontinued. The patient had no further confusional episodes at the most recent follow-up visit, four months after discharge.


carmofur

mitomycin

[ A randomized controlled trial of immunochemotherapy using carmofur ( HCFU ) , mitomycin C and immunopotentiators in advanced gastric cancer following noncurative resection and nonresection ] . The cumulative survival rate of 166 gastric cancer patients after noncurative resection and nonresection treated by combination therapy using carmofur (HCFU), mitomycin C (MMC) and immunopotentiators was investigated. A randomized controlled trial composed of MMC and immunopotentiators (group A) versus the addition of HCFU to group A (group B) was undertaken. In all patients, the survival curve of group B was superior to that of group A (g. Wilcoxon test, p = 0.078). Noncurative resection or nonresection patients presented significantly higher survival rates in group B (p less than 0.05) after analysis according to the duration of the treatment period (Z-test). Stratification of backgrounds for noncurative patients also showed significantly higher survival rates in group B (p less than 0.05) at S 3, P, stage IV. From these results, it might be suggested that HCFU therapy is useful for gastric cancer patients after noncurative resection and nonresection.


Obinutuzumab

Lenalidomide

lenalidomide

obinutuzumab

Lenalidomide triggers T-cell effector functions in vivo in patients with follicular lymphoma. The immunomodulatory drug lenalidomide is used in patients with follicular lymphoma (FL) with the aim of stimulating T-cell antitumor immune response. However, little is known about the effects of lenalidomide on T-cell biology in vivo in patients with FL. We thus undertook an extensive longitudinal immunologic study , including phenotypic , transcriptomic , and functional analyses , on 44 first-line and 27 relapsed/refractory patients enrolled in the GALEN trial ( Obinutuzumab Combined With Lenalidomide for Relapsed or Refractory Follicular B-Cell Lymphoma ) to test the efficacy of lenalidomide and obinutuzumab combination in patients with FL . lenalidomide rapidly and transiently induced an activated T-cell phenotype, including HLA-DR, Tim-3, CD137, and programmed cell death protein 1 (PD-1) upregulation. Furthermore, sequential RNA-sequencing of sorted PD-1+ and PD-1- T-cell subsets revealed that lenalidomide triggered a strong enrichment for several gene signatures related to effector memory T-cell features, including proliferation, antigen receptor signaling, and immune synapse restoration; all were validated at the phenotypic level and with ex vivo functional assays. Correlative analyses pinpointed a negative clinical impact of high effector T-cell and regulatory T-cell percentages before and during treatment. Our findings bring new insight in lenalidomide mechanisms of action at work in vivo and will fuel a new rationale for the design of combination therapies.


propranolol

pindolol

Beta-blockade and brachial artery hemodynamics in hypertension. The effect of systemic adrenergic blockade on hypertensive brachial arteries was studied in humans with pulsed Doppler flowmetry. Blockade of beta-receptors by the nonselective beta-blocking agent propranolol did not modify the brachial artery diameter , whereas pindolol increased this parameter for the same degree of blood pressure reduction . The beta1-selective blocking agents atenolol and bisoprolol caused similar decreases in blood pressure and a reduction in the diameters of the brachial artery and abdominal aorta, respectively. The combination of alpha- and beta-blockade produced a rapid drop in blood pressure but did not change the brachial arterial diameter. Thus, following beta-blockade, the arterial diameter increased, did not change, or even decreased despite an adequate blood pressure reduction. It is suggested that beta-blockade in some instances resets the pressure-diameter curve and therefore has a direct action on the arterial wall independent of the mechanical effect of blood pressure reduction.


Nab-paclitaxel

paclitaxel

carboplatin

bevacizumab

nab-paclitaxel

Nab-paclitaxel/bevacizumab/carboplatin chemotherapy in first-line triple negative metastatic breast cancer. Triple negative metastatic breast cancer can be difficult to treat with primarily cytotoxic options. Nab-paclitaxel has demonstrated improved PFS and tolerability compared with standard cremophor-solubilized paclitaxel ; based on this , we examined the efficacy and safety of combining weekly nab-paclitaxel with carboplatin and bevacizumab in TNMBC . ### Patients And Methods In this phase II, multicenter trial, patients with first-line TNMBC received nab-paclitaxel (100 mg/m(2)) and carboplatin (area under the curve = 2) on days 1, 8, 15, and bevacizumab (10 mg/kg) on days 1 and 15 of a 28-day cycle. The primary end point was safety and tolerability and secondary end points included PFS, ORR, and CBR. PFS was calculated using the Kaplan-Meier method. ### results Between July 16, 2007, and October 3, 2011, 34 patients were enrolled at 4 centers. Median age was 50.0 (range, 30-76) years and 77% (n = 26) of patients received previous adjuvant therapy. Median PFS was 9.2 months (95% confidence interval [CI], 7.8-25.1 months). The CBR was 94% (95% CI, 80%-99%), and ORR was 85% (95% CI, 69%-95%) for the combination. The regimen was well tolerated with the most common grade 3/4 adverse events being neutropenia (n = 18; 53%) and thrombocytopenia (n = 6; 18%), with other serous events including 1 grade 3 and 1 grade 4 thrombotic event and 1 febrile neutropenia. ### conclusion The combination of nab-paclitaxel, bevacizumab, and carboplatin as first-line treatment for TNMBC was efficacious and well tolerated. The PFS, CBR, and ORR, and tolerability of the regimen, compares favorably with other standard first-line therapies.


gentamicin

clindamycin

Renal failure following gentamicin in combination with clindamycin.  Acute renal failure ( ARF ) occurred concomitantly with the administration of gentamicin in combination with clindamycin in three patients in whom no other known predisposing cause of ARF could be demonstrated . The evidence for combined nephrotoxicity consisted of the temporal relationship between administration of the antibiotics and the development of ARF, and the prompt improvement in renal function upon cessation of therapy. Complete or partial recovery of renal function occured in all patients. Renal function should be carefully monitored in patients receiving this antibiotic combination.


nicotinamide

isoniazid

Protection of Escherichia coli from isoniazid inhibition. Inhibition of Escherichia coli by isonicotinic acid hydrazide (isoniazid) is a function of the initial cell concentration, concentration of antibiotic, and chemical composition of the medium. An initial concentration of 5 x 10(5) cells/ml in a minimal medium is inhibited by 1 mM isoniazid. The E. coli cells are protected from this inhibitory effect by a high concentration of cells in the medium. Protection is also obtained from vitamin-free Casamino Acids, methionine, or choline plus homocystine. However , nicotinic acid , nicotinamide , and pyridoxamine are not able to reverse the effect of isoniazid . Colonies arising on minimal medium supplemented with isoniazid are not due to selection of resistant mutants, because this resistance is transitory and not passed on to the daughter cells. It is hypothesized that this transitory resistance is a manifestation of the cells' ability to transfer the methyl group of methionine to either isoniazid or accumulated nicotinic acid and/or nicotinamide.


pegfilgrastim

rituximab

A Phase II Trial of Rituximab Combined With Pegfilgrastim in Patients With Indolent B-cell Non-Hodgkin Lymphoma.  To explore the role of augmenting neutrophil function in B-cell lymphoma , we conducted a phase II study evaluating the safety and clinical efficacy of pegfilgrastim and rituximab in low-grade CD20 ### Patients And Methods Twenty patients with indolent B-NHL were treated with rituximab (375 mg/m ### results The patient demographics included median age of 64 years, 70% were male, 70% had follicular lymphoma, and 90% had stage III-IV disease. The median number of previous therapies was 2 (range, 0-5); 90% had received previous anti-CD20 monoclonal antibody therapy. The addition of pegfilgrastim to rituximab did not increase rituximab-related toxicities. The overall response rate was 60% (12 of 20), with a complete response (CR) rate of 35% (7 of 20). The median progression-free survival (PFS) duration was 17.9 months (95% confidence interval, 9.9-27.6 months); the median overall survival was not reached. A shorter time-to-peak oxidative burst after the first dose of pegfilgrastim was associated with greater CR rates (P = .04) and longer PFS (P = .03). ### conclusion The pegfilgrastim-rituximab combination was well tolerated, with favorable outcomes compared with historical controls. A shorter time-to-peak oxidative burst was associated with higher CR rates and longer PFS. Our results support further evaluation of strategies that enhance the innate immune system to improve rituximab activity in B-NHL.


aflibercept

dexamethasone

aflibercept

Sequential Dexamethasone and Aflibercept Treatment in Patients with Diabetic Macular Edema: Structural and Functional Outcomes at 52 Weeks.  The aim of this paper is to compare intravitreous aflibercept versus dexamethasone implant followed by aflibercept ( sequential treatment group ) in patients with diabetic macular edema ( DME ) . ### methods We conducted an observational retrospective study in naïve DME patients, 15 treated only with aflibercept (a monthly injection for the first 5 consecutive doses, followed by an injection every 2 months), and 15 treated with a single dexamethasone implant followed by bimonthly aflibercept. Best-corrected visual acuity (BCVA), central macular thickness (CMT), and qualitative features as well as adverse events were assessed at baseline and at 2, 6, and 12 months. ### results BCVA increased from 70.8 ± 4.1 to 83.5 ± 2.7 letters with aflibercept and from 75.6 ± 2.7 to 86.5 ± 2.5 with sequential treatment (p = 0.551). CMT decreased from 411 ± 26.1 to 288.1 ± 10.5 with aflibercept and from 411.4 ± 24.3 to 260.8 ± 17.9 in the sequential treatment group. The differences between the 2 groups, in terms of visual gain and decreased MT, were not statistically significant (p > 0.05). Nine and 6 injections and 9 and 7 monitoring visits were performed. ### conclusion Sequential treatment in DME, starting with dexamethasone and followed by aflibercept, is a promising alternative that can reduce the treatment burden in the first year without statistically significant differences in terms of visual gain and decreased MT compared to aflibercept only.


paclitaxel

carboplatin

Phase I study of the CD40 agonist antibody CP-870,893 combined with carboplatin and paclitaxel in patients with advanced solid tumors. CD40 is a cell-surface molecule that critically regulates immune responses. CP-870,893 is a fully human, CD40-specific agonist monoclonal antibody (mAb) exerting clinical antineoplastic activity. Here, the safety of CP-870,893 combined with carboplatin and paclitaxel was assessed in a Phase I study. Patients with advanced solid tumors received standard doses of paclitaxel and carboplatin on day 1 followed by either 0.1 mg/Kg or 0.2 mg/Kg CP-870,893 on day 3 ( Schedule A ) or day 8 ( Schedule B ) , repeated every 21 d. The primary objective was to determine safety and maximum-tolerated dose (MTD) of CP-870,893. Secondary objectives included the evaluation of antitumor responses, pharmacokinetics and immune modulation. Thirty-two patients were treated with CP-870,893, 16 patients on each schedule. Two dose-limiting toxicities were observed (grade 3 cytokine release and transient ischemic attack), each at the 0.2 mg/Kg dose level, which was estimated to be the MTD. The most common treatment-related adverse event was fatigue (81%). Of 30 evaluable patients, 6 (20%) exhibited partial responses constituting best responses as defined by RECIST. Following CP-870,893 infusion, the peripheral blood manifested an acute depletion of B cells associated with upregulation of immune co-stimulatory molecules. T-cell numbers did not change significantly from baseline, but transient tumor-specific T-cell responses were observed in a small number of evaluable patients. The CD40 agonist mAb CP-870,893, given on either of two schedules in combination with paclitaxel and carboplatin, was safe for patients affected with advanced solid tumors. Biological and clinical responses were observed, providing a rationale for Phase II studies.


paclitaxel

docetaxel

Design and development of new combinations of the CMF agents with taxanes (paclitaxel or docetaxel) in advanced breast cancer: a feasibility study. We previously designed and tested combinations made up of the CMF agents, two at a time by rotation, and of doxorubicin or epirubicin. The present study was aimed to similarly test new combinations made up of the CMF agents, two at a time by rotation, and paclitaxel or docetaxel. ### methods The doses of each taxane were escalated with the objective of reaching at least a single dose level of 90 mg/m2 of paclitaxel and 45 mg/m2 of docetaxel on days 1 and 8 of each four-week cycle. Thirty-two patients with advanced breast carcinoma were randomized to receive increasing doses of paclitaxel ( 45 , 65 , 80 , 90 and 100 mg/m2 ) or docetaxel ( 30 , 35 , 40 , 45 and 50 mg/m2 ) together with the CMF agents at the same dose as that used in the conventional regimen . Each dose level was administered to a triplet of patients. No direct comparison of the two taxanes was made. ### results The fourth dose level was reached for paclitaxel and docetaxel. The most important toxicities were grade 4 neutropenia and grade 1-2 nausea/vomiting and stomatitis. The objective response rate, assessed only after the third cycle at any dose level, was 31% (95% CI, 15-47%). ### conclusions The combinations of the CMF agents (two at a time in rotation) with paclitaxel (90 mg/m2) or docetaxel (45 mg/m2) on days 1 and 8 of each four-week cycle are feasible and lead to definite signs of therapeutic activity, and the side effects are generally mild. Further studies are therefore warranted.


fenofibric

atorvastatin

rosuvastatin

simvastatin

Fenofibric acid: in combination therapy in the treatment of mixed dyslipidemia. fenofibric acid activates peroxisome proliferator-activated receptor alpha to modify fatty acid and lipid metabolism. fenofibric acid is the first member of the fibric acid derivatives (fibrates) class approved for use as combination therapy with HMG-CoA reductase inhibitors (statins). In three randomized, double-blind, multicenter, phase III trials in adult patients with mixed dyslipidemia, up to 12 weeks' treatment with once-daily fenofibric acid 135 mg plus a low- or moderate-dose statin (atorvastatin 20 or 40 mg, rosuvastatin 10 or 20 mg, or simvastatin 20 or 40 mg) improved high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) levels to a significantly greater extent than statin monotherapy, and improved low-density lipoprotein cholesterol (LDL-C) levels to a significantly greater extent than fenofibric acid monotherapy. In a 52-week , open-label , multicenter , extension study , HDL-C , TG , and LDL-C levels continued to improve , or were maintained , during combination therapy with once-daily fenofibric acid 135 mg plus a moderate-dose statin ( atorvastatin 40 mg , rosuvastatin 20 mg , or simvastatin 40 mg ) . Once-daily fenofibric acid 135 mg plus a statin was generally as well tolerated as monotherapy with fenofibric acid 135 mg/day or the corresponding statin dosage in the three phase III trials in patients with mixed dyslipidemia. The incidence of adverse events was similar between the combination therapy group and both monotherapy groups. In the extension trial, once-daily fenofibric acid 135 mg plus a moderate-dose statin (atorvastatin 40 mg, rosuvastatin 20 mg, or simvastatin 40 mg) for up to 52 weeks was generally well tolerated.


lamivudine

zidovudine

zidovudine

Safety and efficacy of lamivudine-zidovudine combination therapy in zidovudine-experienced patients. A randomized controlled comparison with zidovudine monotherapy. Lamivudine European HIV Working Group.  To compare the safety and efficacy of 2 doses of lamivudine given in combination with zidovudine with continued zidovudine monotherapy . ### design Double-blind, randomized, multicenter, comparative trial of 223 patients treated for 24 weeks. ### setting Patients from 32 hospitals in Europe were enrolled throughout a 1-year period. ### patients Adult human immunodeficiency virus type 1 (HIV-1)-positive, zidovudine-experienced ( > or = 24 weeks prior zidovudine) patients with CD4+ cell counts between 0.10 and 0.40 x 10(9)/L (100-400 cells/microL). ### intervention Patients received either 200 mg of zidovudine every 8 hours, 150 mg of lamivudine every 12 hours plus zidovudine, or 300 mg of lamivudine every 12 hours plus zidovudine for 24 weeks. All patients were then allowed to receive zidovudine and open-label lamivudine combination therapy. Twelve patients withdrew because of adverse events during the 24-week treatment period. ### Main Outcome Measures Efficacy was measured by evaluating immunological and viral load changes, and safety was assessed by evaluating clinical manifestations and laboratory indexes of toxic effects. ### results Patients receiving low- or high-dose combination therapy had greater treatment effects compared with patients receiving continued zidovudine monotherapy during the first 24 weeks as documented by changes in CD4+ cell counts (+0.04 vs +0.03 vs -0.02 x 10(9)/L, respectively; P < .001); log10 HIV-1 RNA as measured by the Roche assay (-0.96 vs -0.77 vs +0.07 copies/mL, respectively; P < .001) or log10 HIV-1 RNA measured by the quantitative nucleic acid sequence-based amplification assay (-0.59 vs -1.06 vs -0.02 copies/mL, respectively; P < .011); and immune-complex dissociated (ICD) p24 antigen (-74% vs -68% vs +27%, respectively; P < .001). There were no statistically significant differences in viral measurements, in CD4+ cell counts, or in safety profile between the groups receiving 2 doses of lamivudine in combination with zidovudine. The effects on CD4+ cell counts and ICD p24 antigen were sustained throughout 48 weeks for patients continuing combination therapy. Patients switching to combination therapy at week 24 showed improvement. ### conclusion In zidovudine-experienced HIV-1-infected patients, combination treatment with lamivudine and zidovudine is well tolerated and provides greater and more sustained increases in CD4+ cell counts and decreases in viral load than continued zidovudine monotherapy.


Bradykinin

carbachol

Ca(2+)-independent, Ca(2+)-dependent, and carbachol-mediated arachidonic acid release from rat brain cortex membrane. Synaptoneurosomes obtained from the cortex of rat brain prelabeled with [14C]arachidonic acid [( 14C]AA) were used as a source of substrate and enzyme in studies on the regulation of AA release. A significant amount of AA is liberated in the presence of 2 mM EGTA, independently of Ca2+, primarily from phosphatidic acid and polyphosphoinositides (poly-PI). Quinacrine, an inhibitor of phospholipase A2 (PLA2), suppressed AA release by about 60% and neomycin, a putative inhibitor of phospholipase C (PLC), reduced AA release by about 30%. An additive effect was exhibited when both inhibitors were given together. Ca2+ activated AA release. The level of Ca2+ present in the synaptoneurosomal preparation (endogenous level) and 5 microM CaCl2 enhance AA liberation by approximately 25%, whereas 2 mM CaCl2 resulted in a 50% increase in AA release relative to EGTA. The source for Ca(2+)-dependent AA release is predominantly phosphatidylinositol (PI); however, a small pool may also be liberated from neutral lipids. carbachol, an agonist of the cholinergic receptor, stimulated Ca(2+)-dependent AA release by about 17%. Bradykinin enhanced the effect of carbachol by about 10 - 15 % . This agonist-mediated AA release occurs specifically from phosphoinositides (PI + poly-PI). Quinacrine almost completely suppresses calcium-and carbachol-mediated AA release. neomycin inhibits this process by about 30% and totally suppresses the effect of bradykinin. Our results indicate that both phospholipases PLA2 and PLC with subsequent action of DAG lipase are responsible for Ca(2+)-independent AA release. Ca(2+)-dependent and carbachol-mediated AA liberation occurs mainly as the result of PLA2 action. A small pool of AA is probably also released by PLC, which seems to be exclusively responsible for the effect of bradykinin.


gefitinib

erlotinib

Inhibition of the PI3K/AKT pathway potentiates cytotoxicity of EGFR kinase inhibitors in triple-negative breast cancer cells. Triple-negative breast cancers (TNBCs) are known to be intrinsically resistant to inhibitors for epidermal growth factor receptor (EGFR). Until now, clinical trials for TNBCs using EGFR inhibitors (EGFRis) as single agents have yielded disappointing results. Here , we report that combinatorial treatment using EGFRis , such as gefitinib or erlotinib , with PI3K/AKT pathway inhibitors ( PI3K/AKTis ) demonstrated a synergistic , anti-proliferative effect in cell lines of the basal-like ( BL ) subtype , a subtype of TNBC . Western blot analysis revealed that the gefitinib/PI-103 combination significantly reduced the level of both phospho-AKT and phospho-ERK in two susceptible BL subtype cell lines, SUM149PT and MDA-MB-468, whereas it had little or no effect on the level of phospho-ERK in two non-susceptible cell lines (HS578T and MDA-MB-231) of mesenchymal stem-like (MSL) TNBC subtype. The gefitinib/PI-103 combination also significantly induced caspase-3/7-mediated PARP cleavage and reduced two anti-apoptotic proteins, XIAP and Bcl-2 in the susceptible cell lines. In addition, the level of myeloid cell leukemia 1 (Mcl-1) protein was markedly decreased by gefitinib/PI-103 combination in the BL TNBC cells, but showed no significant change by this combination in MSL subtype cells. These results suggest that pharmacological inhibition of EGFR used in combination of PI3K/AKTis is a potential therapeutic approach to treat a subtype of TNBCs.


gemcitabine

capecitabine

dovitinib

A Phase Ib Study of the FGFR/VEGFR Inhibitor Dovitinib With Gemcitabine and Capecitabine in Advanced Solid Tumor and Pancreatic Cancer Patients. Preclinical studies demonstrated antitumor activity of dovitinib in pancreatic cancer models. This phase Ib study aimed to determine the maximum tolerated dose (MTD) of dovitinib in combination with gemcitabine and capecitabine and to characterize the safety and pharmacokinetic profile in patients with advanced pancreatic and biliary tract cancers and solid malignancies. ### Materials And Methods Patients received gemcitabine 1000 mg/m² intravenously on days 1 and 8 , capecitabine 1300 mg/m² oral daily from day 1 to 14 , and dovitinib oral daily 5 days on and 2 days off , every 21-day cycle . The standard 3+3 dose escalation design was utilized and the study expanded to treat an additional 20 advanced pancreatic and biliary tract cancers patients at MTD. ### results A total of 29 patients were enrolled. One patient experienced dose-limiting grade 3 colitis. Two patients developed clinically significant neuropathy after the first cycle requiring dose reduction. The MTD was not reached and dovitinib 300 mg was declared the recommended dose for expansion. The most frequent grade 2 or worse adverse events were fatigue (45%), neutropenia (41%), thrombocytopenia (34%), anemia (24%), nausea (24%), and palmer-plantar erythrodysaesthesia syndrome (21%). Partial responses were observed in 5 patients. Pharmacokinetic studies showed no drug-drug interaction between dovitinib, capecitabine and gemcitabine. Fibroblast growth factor 23 plasma level increased in 4 of 5 patients during the first cycle of treatment. ### conclusions dovitinib 300 mg daily is the recommended dose when combined with gemcitabine and capecitabine, achieving clinically relevant plasma concentrations. The study combination demonstrated encouraging efficacy signals in advanced pancreatic cancer.


oxaliplatin

doxorubicin

Oxaliplatin and Doxorubicin for relapsed or refractory high-risk neuroblastoma. Patients with relapsed or refractory neuroblastoma have poor long-term survival. New therapeutic regimens are needed. doxorubicin and cisplatin are commonly used in the treatment of high-risk neuroblastoma. oxaliplatin, a platinum compound with a 1,2-diaminocyclohexan carrier ligand, is more potent than cisplatin with less nephrotoxicity and ototoxicity. We treated seven relapsed/refractory neuroblastoma patients using oxaliplatin (105-130 mg/m(2)) and doxorubicin (60-75 mg/m(2)) together with dexrazoxane (10 mg/mg of doxorubicin) administered intravenously every three weeks. Prolonged thrombocytopenia causing treatment delay was observed when oxaliplatin was administered at 130 mg/m(2). A reduced dose of oxaliplatin 105 mg/m(2 ) on day 1 with doxorubicin at 20 mg/m(2)/dose on days 1 - 3 was well tolerated . Sensory neuropathies were mild and transient. No cardiotoxicity was noted despite all patients having a history of prior anthracycline exposure. Best responses included 1 complete response, 1 partial response, 1 mixed response, 3 stable diseases. In our cohort of heavily pretreated relapsed and refractory neuroblastoma patients, the combination of oxaliplatin and doxorubicin demonstrated anti-tumor activity and merits further investigation.


trebananib

cediranib

Beyond Bevacizumab: An Outlook to New Anti-Angiogenics for the Treatment of Ovarian Cancer. In addition to the monoclonal vascular endothelial growth factor (VEGF) antibody bevacizumab, several alternative anti-angiogenic treatment strategies for ovarian cancer patients have been evaluated in clinical trials. Apart from targeting extracellular receptors by the antibody aflibercept or the peptibody trebananib, the multikinase inhibitors pazopanib, nintedanib, cediranib, sunitinib, and sorafenib were developed to interfere with VEGF receptors and multiple additional intracellular pathways. nintedanib and pazopanib significantly improved progression-free survival in two positive phase III trials for first-line therapy. A reliable effect on overall survival could, however, not be observed for any anti-angiogenic first-line therapies so far. In terms of recurrent disease , two positive phase III trials revealed that trebananib and cediranib are effective anti-angiogenic agents for this indication . Patient selection and biomarker guided prediction of response seems to be a central aspect for future studies. Combining anti-angiogenics with other targeted therapies to possibly spare chemotherapy in certain constellations represents another very interesting future perspective for clinical trials. This short review gives an overview of current clinical trials for anti-angiogenic treatment strategies beyond bevacizumab. In this context, possible future perspectives combining anti-angiogenics with other targeted therapies and the need for specific biomarkers predicting response are elucidated.


tamsulosin

tolterodine

tamsulosin

Does Combination Therapy with Tamsulosin and Tolterodine Improve Ureteral Stent Discomfort Compared with Tamsulosin Alone? A Double-Blind, Randomized, Controlled Trial. Ureteral stent discomfort is a significant postoperative problem for many patients. Despite the use of narcotics and α-blockers patients often experience bothersome lower urinary tract symptoms and pain, which impair daily activities. We compared combination therapy with an α-blocker and an anticholinergic to monotherapy with an α-blocker. ### Materials And Methods A double-blind, randomized, controlled trial was performed from December 2012 to April 2014. A total of 80 patients were randomized , including 44 to the combination group ( tamsulosin 0.4 mg and tolterodine early release 4 mg ) and 36 to the monotherapy group ( tamsulosin 0.4 mg and placebo ) . Patients with preexisting ureteral stent placement or current anticholinergic therapy were excluded from study. Patients completed USSQ (Urinary Stent Symptom Questionnaire) before stent placement on the day of surgery, the day after stent placement, the morning of stent removal and the day after stent removal. The questionnaire included questions regarding urinary symptoms, general health, body pain, and work and sexual history. ### results A total of 80 patients (40 males and 40 females) were studied. Mean age was 51.5 vs 51.3 years (p = 0.95) and mean body mass index was 33.6 vs 31.9 kg/m(2) (p = 0.44) in monotherapy group 1 vs combination therapy group 2. Between the 2 groups there was no significant difference in urinary symptoms, body pain and activities of daily living from baseline to just before stent removal (p = 0.95, 0.40 and 0.95, respectively). Although there was no difference between the groups, both showed improvement in urinary symptoms from the time of initial stent insertion to just prior to stent removal (difference -0.50 for combination therapy and -0.40 for monotherapy). The mean stent indwelling time of 9.6 and 8.7 days in the combination and monotherapy groups, respectively, did not differ (p = 0.67). On ANOVA it had no significant impact on results (p = 0.64). ### conclusions Combination therapy with tamsulosin and tolterodine does not appear to improve urinary symptoms, bodily pain or quality of life in patients after ureteral stent placement for nephrolithiasis compared to tamsulosin alone. Both groups experienced worse urinary symptoms, pain and quality of life with a stent, suggesting that further research is necessary to improve stent discomfort.


dexamethasone

quinine

Proteasome inhibitors modulate anticancer and anti-proliferative properties via NF-kB signaling, and ubiquitin-proteasome pathways in cancer cell lines of different organs. Cancer is second most common cause of death in the United State. There are over 100 different types of cancer associated with different human organs, predominantly breast, liver, pancreas, prostate, colon, rectum, lung, and stomach. We have recently reported properties of pro-inflammatory (for treatment of various types of cancers), and anti-inflammatory (for cardiovascular disease and diabetes) compounds. The major problem associated with development of anticancer drugs is their lack of solubility in aqueous solutions and severe side effects in cancer patients. Therefore, the present study was carried out to check anticancer properties of selected compounds, mostly aqueous soluble, in cancer cell lines from different organs. ### methods The anticancer properties, anti-proliferative, and pro-apoptotic activity of novel naturally occurring or FDA approved, nontoxic, proteasome inhibitors/activators were compared. In addition to that, effect of δ-tocotrienol on expression of proteasome subunits (X, Y, Z, LMP7, LMP2, LMP10), ICAM-1, VCAM-1, and TNF-α using total RNAs derived from plasmas of hepatitis C patients was investigated. ### results Our data demonstrated that following compounds are very effective in inducing apoptosis of cancer cells: Thiostrepton, dexamethasone, 2-methoxyestradiol, δ-tocotrienol, quercetin, amiloride, and quinine sulfate have significant anti-proliferation properties in Hela cells (44% - 87%) with doses of 2.5-20 μM, compared to respective controls. Anti-proliferation properties of thiostrepton, 2-methoxyestradiol, δ-tocotrienol, and quercetin were 70% - 92%. However , thiostrepton , dexamethasone , 2-methoxyestradiol , δ-tocotrienol , quercetin , and quinine sulphate were effective in pancreatic , prostate , breast , lungs , melanoma , Β-lymphocytes , and T-cells ( Jurkat : 40 % to 95 % ) compared to respective controls . In lung cancer cells, these compounds were effective between 5 and 40 μM. The IC ### conclusions These data demonstrate effectiveness of several natural-occurring compounds with anti-proliferative properties against cancer cells of several organs of humans. Thiostrepton, dexamethasone, 2-methoxyestradiol, δ-tocotrienol and quercetin are very effective for apoptosis of cancer cells in liver, pancreas, prostate, breast, lung, melanoma, Β-lymphocytes and T-cells. The results have provided an opportunity to test these compounds either individually or in combination as dietary supplements in humans for treatment of various types of cancers.
