Kinds of Monotherapy Terms modified by Monotherapy Selected AbstractsThyroid Function in Girls with Epilepsy with Carbamazepine, Oxcarbazepine, or Valproate Monotherapy and after Withdrawal of MedicationEPILEPSIA, Issue 3 2004Leena K. Vainionpää Summary: Purpose: Antiepileptic drugs may affect the serum thyroid hormone concentrations. The aim of this study was to evaluate thyroid function in 78 girls taking carbamazepine (CBZ), oxcarbazepine (OXC), or valproate (VPA) monotherapy for epilepsy and after withdrawal of the treatment. Methods: Forty-one girls taking VPA, 19 taking CBZ, and 18 taking OXC for epilepsy, as well as 54 healthy age-matched controls, aged 8 to 18 years, participated in the study. All the girls were examined clinically, and their pubertal stage was assessed. Blood samples were obtained for thyroid hormone and antibody assays. These examinations were repeated after a mean follow-up of 5.8 years to assess thyroid function, and 64 (82%) of 78 patients and 42 (78%) of 54 controls agreed to participate in the second evaluation. Results: In the first evaluation, the mean serum thyroid hormone concentrations were lower in the girls taking CBZ [thyroxine (T4), 70.2; SD, 10.9 nM; and free thyroxine (FT4), 11.5; SD, 1.8 pM] or OXC (T4, 74.9; SD, 16.4 nM; and FT4, 11.3; SD, 1.8 pM) than in the control girls (T4, 96.6; SD, 15.1 nM, and FT4, 14.4; SD, 1.5 pM; p < 0.001, all comparisons). However, thyrotropin (TSH) concentrations were normal in the girls taking CBZ or OXC. Sixty-three% of the girls taking CBZ and 67% of the girls taking OXC had serum T4 and/or FT4 levels below the lower limit of the reference range. The VPA-treated girls with epilepsy had normal serum T4 and FT4 concentrations, but slightly increased TSH levels (3.3; SD, 1.5 mU/L; p < 0.01) compared with the control girls (2.5; SD, 1.0 mU/L). Normal serum hormone concentrations were restored in the patients who discontinued the medication. Conclusions: Both CBZ and OXC reduce serum thyroid hormone concentrations in girls with epilepsy. Conversely, VPA is associated with normal serum thyroid hormone and increased thyrotropin levels. However, our results suggest that the changes in serum thyroid hormone and thyrotropin levels are reversible after withdrawal of the medication.

Schulpis Summary: ,Purpose: Valproic acid (VPA) is an effective antiepileptic drug (AED), which is associated with dose-related adverse reactions such as skin rash, hair loss (alopecia), etc. Profound as well as partial biotinidase deficiency causes dermatologic manifestations similar these. Therefore, it was of interest to evaluate serum biotinidase activity in patients receiving VPA monotherapy. Methods: Seventy-five patients with seizures, mean age, 8.6 years (±1.9 years) were divided into three groups. Group A (n = 25) was treated with VPA 28.7 ± 8.5 mg/kg/24 h, group B (n = 25) with 41.6 ± 4.9 mg/kg/24 h, and group C with 54.5 ± 5.8 mg/kg/24 h. Their "trough" VPA serum levels were 40.9 ± 13.2, 86.25 ± 11.5, and 137 ± 14.5 ,g/ml, respectively. Fifty healthy children were the controls. Patients and controls underwent clinical and laboratory evaluations including liver function data, complete blood counts, NH3, and so on, after 45 days of VPA treatment. Biotinidase serum levels were evaluated fluorometrically. Results: Liver function data were found elevated in the groups B and C. On the contrary, biotinidase activity was significantly statistically lowered (p < 0.001) in groups B and C (1.22 ± 1.11, 0.97 ± 0.07 mmol/min/L respectively), as compared with controls (5.20 ± 0.90 mmol/min/L). Strong inverse correlations were observed between liver enzymes and VPA blood levels with the activity of the enzyme. Additionally, no inhibitory effect on biotinidase activity was found, when the enzyme was incubated in vitro with high (1.2 mM) concentrations of the drug. Skin lesions (seborrheic rash, alopecia) were improved in our patients after biotin (10 mg/day) supplementation. Conclusions: It is suggested that VPA impairs the liver mitochondrial function, resulting in a low biotinidase activity and or biotin deficiency. Biotin supplementation could restore some of the side effects of the drug. [source] Gorham-Stout Disease,Stabilization During Bisphosphonate Treatment,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2005Fabian Hammer Abstract A 45-year-old woman presented with recent onset of left-sided chest pain. On clinical examination, these symptoms seemed to be strictly localized to a region that was marked by a long-standing cutaneous erythematous lesion. Laboratory results showed no gross abnormalities. Radiological imaging including conventional X-ray, MRI scans, and 3D CT reconstruction of the rib cage revealed circumscript destruction of the left lateral ribs 9,11. Histological analysis of a rib biopsy showed angiomatous hypervascularization and intracortical fibrosis. In keeping with these findings, the patient's condition was diagnosed as Gorham-Stout disease, a rare condition with localized, often unilateral, bone destruction. Monotherapy with bisphosphonates (pamidronate 30 mg IV every 3 months) was initiated, leading to rapid disappearance of local pain. Follow-up over 24 months documented a stable clinical and radiological picture without evidence of progressive bone destruction. [source] Antihypertensive Efficacy of the Oral Direct Renin Inhibitor Aliskiren as Add-On Therapy in Patients Not Responding to Amlodipine MonotherapyJOURNAL OF CLINICAL HYPERTENSION, Issue 10 2007Waymon Drummond MD This study investigated the addition of the direct renin inhibitor aliskiren to amlodipine in patients with mild to moderate hypertension that was inadequately controlled with amlodipine alone. Following once-daily treatment with amlodipine 5 mg for 4 weeks, patients whose hypertension responded inadequately to therapy (mean sitting diastolic blood pressure [DBP] 90,109 mm Hg) (n=545) were randomized to 6 weeks of double-blind treatment with amlodipine 5 mg plus aliskiren 150 mg, amlodipine 5 mg, or amlodipine 10 mg. At the study's end, mean systolic blood pressure and DBP reductions with the combination of aliskiren 150 mg and amlodipine 5 mg (11.0/8.5 mm Hg) were significantly greater (P<.0001) than with amlodipine 5 mg (5.0/4.8 mm Hg),the comparator group,but similar to amlodipine 10 mg (9.6/8.0 mm Hg). All treatments were well tolerated. Edema occurred more frequently with amlodipine 10 mg (11.2%) than with combination therapy (2.1%) or amlodipine 5 mg (3.4%). In conclusion, aliskiren 150 mg plus amlodipine 5 mg shows similar but not better blood pressure-lowering efficacy when compared with amlodipine 10 mg in patients not completely responsive to amlodipine 5 mg; less edema was noted with combination therapy. [source] Combination therapy of thymosin alpha-1 and lamivudine for HBeAg positive chronic hepatitis B: A prospective randomized, comparative pilot studyJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 5 2008Hyun Woong Lee Abstract Background and Aim:, Monotherapy of lamivudine, interferon-alpha (IFN-,), and thymosin alpha-1 (T,1) is unlikely to be sufficient for the eradication of a chronic hepatitis B virus (HBV) infection. The aim of our study is to elucidate whether the combination of T,1 and lamivudine is superior to lamivudine monotherapy in hepatitis B e antigen (HBeAg) positive naïve patients with chronic hepatitis B. Methods:, Sixty-seven patients were assigned to two different groups in a randomized manner. The combination group (n = 34) received T,1 (1.6 mg subcutaneously, twice a week) and lamivudine (100 mg orally, daily) for 24 weeks, followed by continuous lamivudine therapy. The monotherapy group (n = 33) received lamivudine monotherapy continuously. Results:, The incidence of HBeAg seroconversion at 24 weeks was 26.5% (9/34) in the combination group and 6.1% (2/33) in the monotherapy group (P = 0.024). However, there was no statistically significant difference between 26.5% (9/34) in the combination group and 12.1% (4/33) in the monotherapy group at 52 weeks (P = 0.138). The emergence of viral breakthrough gradually increased to 35.3% (12/34) in the combination group, and to 21.2% (7/33) in the monotherapy group at 52 weeks (P = 0.201). Conclusions:, The combination treatment of T,1 and lamivudine did not have an obvious benefit of virological and biochemical response as compared to the lamivudine monotherapy during the combination period. In addition, after the cessation of T,1 treatment, the combination therapy did not prevent the occurrence of viral and biochemical breakthroughs. [source] Systemic therapy of disseminated malignant melanoma: an evidence-based overview of the state-of-the-art in daily routineJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 10 2007D Nashan Abstract Aims, In the metastatic stage, malignant melanoma is resistant to systemic treatment and carries a poor prognosis. A critical, evidence-based analysis of standard approaches based on an extended search of published literature and from different Internet sources is presented. Material and methods, A critical, evidence-based analysis of standard approaches and their variations to systemic therapy based on an extended search of published literature and from different Internet sources is presented. Few meta-analyses are available. Therefore, assessment of therapies is mainly based on randomized multicentre studies or clinical studies achieving an evidence level grade 1 or 2. Results, Monotherapy with DTIC (dacarbazine) is the standard. Based on overall survival data, polychemotherapies cannot be recommended. Combination of polychemotherapy with the cytokines interferon-, and interleukin-2 substantially augments chemotherapy induced response rates, but a meta-analysis for survival does not support its therapeutic superiority. Biological therapies such as vaccinations have not yet delivered results on a higher evidence level. Thus, immunotherapies as well as chemo-immunotherapies will have to be evaluated in further studies. Conclusions, Although the therapeutic efficacy is very limited, dacarbazine cannot be rejected as standard therapy for disseminated melanoma, because no other therapeutic regimen exhibits a survival benefit over DTIC in an evidence-based analysis. This lack of therapeutic progress over the past 40 years clearly calls for further clinical studies, and patients should be enrolled into clinical trials whenever possible. [source] Review article: specifically targeted anti-viral therapy for hepatitis C , a new era in therapyALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2010C. M. Lange Aliment Pharmacol Ther 2010; 32: 14,28 Summary Background, Novel, directly acting anti-viral agents, also named ,specifically targeted anti-viral therapy for hepatitis C' (STAT-C) compounds, are currently under development. Aim, To review the potential of STAT-C agents which are currently under clinical development, with a focus on agents that target HCV proteins. Methods, Studies evaluating STAT-C compounds were identified by systematic literature search using PubMed as well as databases of abstracts presented in English at recent liver and gastroenterology congresses. Results, Numerous directly-acting anti-viral agents are currently under clinical phase I,III evaluation. Final results of phase II clinical trials evaluating the most advanced compounds telaprevir and boceprevir indicate that the addition of these NS3/4A protease inhibitors to pegylated interferon-alfa and ribavirin strongly improves the chance to achieve a SVR in treatment-naive HCV genotype 1 patient as well as in prior nonresponders and relapsers to standard therapy. Monotherapy with directly acting anti-virals is not suitable. NS5B polymerase inhibitors in general have a lower anti-viral efficacy than protease inhibitors. Conclusions, STAT-C compounds in addition to pegylated interferon-alfa and ribavirin can improve SVR rates at least in HCV genotype 1 patients. Future research needs to evaluate whether a SVR can be achieved by combination therapies of STAT-C compounds in interferon-free regimens. [source] Combination Therapy with Digoxin and Diltiazem Controls Ventricular Rate in Chronic Atrial Fibrillation in Dogs Better than Digoxin or Diltiazem Monotherapy: A Randomized Crossover Study in 18 DogsJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 3 2009A.R.M. Gelzer Background: Atrial fibrillation (AF) with excessively high ventricular rates (VR) occurs in dogs with advanced heart disease. Rate control improves clinical signs in these patients. Optimal drug therapy and target VR remain poorly defined. Hypothesis: Digoxin-diltiazem combination therapy reduces VR more than either drug alone in dogs with high VR AF. Animals: Eighteen client-owned dogs (>15 kg) with advanced heart disease, AF, and average VR on 24-hour Holter > 140 beats per minute (bpm). Methods: After baseline Holter recording, dogs were randomized to digoxin or diltiazem monotherapy, or combination therapy. Repeat Holter evaluation was obtained after 2 weeks; dogs were then crossed over to the other arm (monotherapy or combination therapy) for 2 weeks and a third Holter was acquired. Twenty-four hour average VR, absolute and relative VR changes from baseline, and percent time spent within prespecified VR ranges (>140, 100,140, and <100 bpm) were compared. Correlations between serum drug concentrations and VR were examined. Results: Digoxin (median, 164 bpm) and diltiazem (median, 158 bpm) decreased VR from baseline (median, 194 bpm) less than the digoxin-diltiazem combination (median, 126 bpm) (P < .008 for each comparison). With digoxin-diltiazem, VR remained <140 bpm for 85% of the recording period, but remained >140 bpm for 88% of the recording period with either monotherapy. Serum drug concentrations did not correlate with VR. Conclusions and Clinical Importance: At the dosages used in this study, digoxin-diltiazem combination therapy provided a greater rate control than either drug alone in dogs with AF. [source] Antipsychotic polypharmacy at the University Psychiatric Hospital in Serbia,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 11 2007Nevena Divac Abstract The aim of the study was to analyse the prevalence of polypharmacy with antipsychotic drugs and analyse types of coprescribing episodes at the University Psychiatric Hospital in Serbia. A sample of 120 patients (198 hospitalisations) was analysed. The prevalence of polypharmacy was calculated as the proportion of patients receiving two or more antipsychotic drugs concomitantly for at least 28 days. Total daily antipsychotic drug load was calculated as the number of defined daily doses (DDDs) of drugs per patient per day. It was compared between patients receiving monotherapy and patients receiving polypharmacy. Statistics was performed using standard statistical methods. Monotherapy was prescribed during 32.3% hospitalisations (n,=,64), while polypharmacy was noted in 67.7% (n,=,134). Polypharmacy with two drugs was observed during 126 (63.6%) hospitalisations and three antipsychotics were prescribed concomitantly during 8 (4.1%) hospitalisations. Patients' characteristics were not significantly different between patients who received only monotherapy and patients receiving polypharmacy. Patients on monotherapy had significantly more prior hospitalisations than patients from the other group (t,=,3.94, df,=,119, p,<,0.001). The prevalence of polypharmacy patient episodes (67.7%) is approximately 100% higher than the prevalence observed in developed European countries. The explanation of such prescribing habit of Serbian psychiatrists requires further investigation. The only distinguishing factor between patients receiving monotherapy and patients receiving polypharmacy is the number of prior hospitalisations. Copyright © 2007 John Wiley & Sons, Ltd. [source] Early Withdrawal of Calcineurin Inhibitors and Everolimus Monotherapy in de novo Liver Transplant Recipients Preserves Renal FunctionAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2010M. Masetti We designed a randomized trial to assess whether the early withdrawal of cyclosporine (CsA) followed by the initiation of everolimus (Evr) monotherapy in de novo liver transplantation (LT) patients would result in superior renal function compared to a CsA-based immunosuppression protocol. All patients were treated with CsA for the first 10 days and then randomized to receive Evr in combination with CsA up to day 30, then either continued on Evr monotherapy (Evr group) or maintained on CsA with/without mycophenolate mofetil (CsA group) in case of chronic kidney disease (CKD). Seventy-eight patients were randomized (Evr n = 52; CsA n = 26). The 1-year freedom from efficacy failure in Evr group was 75% versus 69.2% in CsA group, p = 0.36. There was no statistically significant difference in patient survival between the two groups. Mean modification of diet in renal disease (MDRD) was significantly better in the Evr group at 12 months (87.7 ± 26.1 vs. 59.9 ± 12.6 mL/min; p < 0.001). The incidence of CKD stage ,3 (estimated glomerular filtration rate <60 mL/min) was higher in the CsA group at 1 year (52.2% vs. 15.4%, p = 0.005). The results indicate that early withdrawal of CsA followed by Evr monotherapy in de novo LT patients is associated with an improvement in renal function, with a similar incidence of rejection and major complications. [source] Once Daily Calcineurin Inhibitor Monotherapy in Pediatric Liver TransplantationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2010U. D. Ekong This report describes a group of pediatric liver transplant recipients who have undergone once daily calcineurin inhibitor (CNI) monotherapy at Children's Memorial Hospital, Chicago, between January 1, 2001 and November 30, 2008. We defined success as normal liver enzymes at 1 year after dose change, with normal enzymes throughout all follow-up. Patients who did not meet the set criteria or had lost an organ to chronic rejection were not considered for this therapeutic strategy. There were 147 patients in our organ transplant tracking record (OTTR) who were , 5 years post liver transplant. Of these, 56 underwent reduced dose, once daily CNI monotherapy. Patients who met the set criteria were placed on once daily calcineurin inhibitor at half their previous dose. Fifty patients successfully achieved this dose change, while six patients failed at a mean of 3.7 ± 3.2 months following the dosing change. The mean interval from transplant was significantly longer in those patients who were successful compared to those who failed dose change (p < 0.05). Importantly, there have been no graft losses. Reduced dose, once daily CNI monotherapy is safe in carefully selected recipients, with a longer interval post liver transplantation increasing the likelihood of success. [source] Mycophenolate Mofetil Monotherapy for Severe Side Effects of Calcineurin Inhibitors Following Liver TransplantationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2009S. Dharancy Withdrawal of calcineurin inhibitors (CNI) followed by mycophenolate mofetil (MMF) monotherapy after liver transplantation (LT) remains controversial due to the increased risk of acute rejection and graft loss. The aim of the present study, performed in a large cohort of liver-transplanted patients with severe CNI-induced side effects, was to assess renal function recovery, and safety in terms of liver function, of complete CNI withdrawal and replacement by MMF monotherapy. Fifty-two patients treated with MMF monotherapy for CNI-induced toxicity were analyzed. Mean estimated glomerular filtration rate (eGFR) increased significantly during the period of MMF monotherapy, from 37 ± 10 to 44.7 ± 15 mL/min/1.73 m2 at 6 months (p = 0.001) corresponding to a benefit of +17.4% in renal function. eGFR stabilized or improved in 86.5%, 81% and 79% of cases, and chronic renal dysfunction worsened in 13.5%, 19% and 21% of cases, at 6, 12 and 24 months after CNI withdrawal, respectively. Only two patients experienced acute rejection. MMF monotherapy may be efficient at reversing/stabilizing CRD, and appears relatively safe in terms of liver graft function in long-term liver-transplanted patients. However, clinicians must bear in mind the potential risk of rejection and graft loss, and should be very cautious in the management of such ,difficult-to-treat patients'. [source] Two Hundred Living Donor Kidney Transplantations Under Alemtuzumab Induction and Tacrolimus Monotherapy: 3-Year Follow-UpAMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2009H. P. Tan Alemtuzumab has been used in off-label studies of solid organ transplantation. We extend our report of the first 200 consecutive living donor solitary kidney transplantations under alemtuzumab pretreatment with tacrolimus monotherapy and subsequent spaced weaning to 3 years of follow-up. We focused especially on the causes of recipient death and graft loss, and the characteristics of rejection. The actuarial 1-, 2- and 3-year patient and graft survivals were 99.0% and 98.0%, 96.4% and 90.8% and 93.3% and 86.3%, respectively. The cumulative incidence of acute cellular rejection (ACR) at the following months was 2%,6, 9.0%,12, 16.5%,18, 19.5%,24, 23.5%,30, 24.0%,36 and 25%,42. The mean serum creatinine (mg/dL) and glomerular filtration rate (mL/min/1.73 m2) at 1 and 3 years were 1.4 ± 0.6 and 58.7 ± 21.6 and 1.5 ± 0.7 and 54.9 ± 20.9, respectively. Fifty (25%) recipients had a total of 89 episodes of ACR. About 88.7% of ACR episodes were Banff 1, and of those, 82% were steroid-sensitive. Nine (4.5%) recipients had antibody-mediated rejection (AMR). About 76.5% were weaned but only 46% are currently on spaced dose (qod or less) tacrolimus monotherapy, and 94.4% remained steroid-free from the time of transplantation. Infectious complications were uncommon. This experience suggests the 3-year efficacy of this approach. [source] Long-term outcome of antiandrogen monotherapy in advanced prostate carcinoma: 12-year results of a phase II studyBJU INTERNATIONAL, Issue 6 2003V. Serretta OBJECTIVE To present the long-term outcome of patients with locally advanced or metastatic prostate carcinoma treated by first-line antiandrogen monotherapy. PATIENTS AND METHODS From 1983 to 1990, 41 patients with advanced prostate carcinoma were treated with flutamide monotherapy until progression or the appearance of toxicity. Twenty-five patients (61%) had T3-T4N0M0 and 16 (39%) T2,4N0,3M1 prostate carcinoma. Consensus criteria were adopted to evaluate the response. Plasma testosterone and sexual function were recorded for the first 3 years. RESULTS Flutamide was administered for up to 147 months; seven patients (17%) interrupted the treatment because of toxicity. There was an objective response in 17 (41%) patients; 20 (49%) had stable disease while four (10%) progressed. There were objective responses, lasting up to 150 months, in 82% of those with M0 and in 18% with M1 disease (P = 0.05). The median time to progression in patients with an objective response and stable disease was 45 and 16 months, respectively (P < 0.001). Thirty-one patients (76%) died from prostate cancer and 10 (24%) from unrelated diseases. The median survival was 67 and 36 months in patients with an objective response and stable disease, respectively (P < 0.001). There was an improvement in performance status in 85% and reduction in bone pain in 83% of the patients; sexual activity was maintained in 63%. CONCLUSION Monotherapy with flutamide is well tolerated. Objective responses are more frequent in patients with locally advanced disease. Patients with an objective response within 6 months have a prolonged progression-free and overall survival. [source] Levetiracetam monotherapy for childhood occipital epilepsy of gastautACTA NEUROLOGICA SCANDINAVICA, Issue 5 2009A. Verrotti Objectives ,, The aim of this open label pilot study was to evaluate the efficacy and tolerability of levetiracetam (LEV) as ,de novo' monotherapy in children and adolescents with late onset childhood occipital epilepsy,Gastaut type (COE-G). Material and methods ,, Twelve patients suffering from COE-G were enrolled in this prospective study. The age of seizures onset ranged from 6.1 to 16.2 years with a peak of frequency at mean (±SD) 10.54 ± 2.77 years. Therapy with LEV was started at 10 mg/kg/day and, after titration, the final dose was generally achieved within 4 weeks and ranged from 20.7 to 45.2 mg/kg/day. Results ,, At the 6 month evaluation, 11 (91.6%) of the 12 patients studied were seizure free, and one (8.3%) showed four additional episodes. Electroencephalography (EEG) activity was normal in six (54.5%) patients, unchanged in two (18.1%) children, and in four (33.3%) patients sporadic occipital abnormalities persisted. At the 12-month evaluation all patients were completely seizure free. Four patients (33.3%) continued to show some EEG abnormalities, while eight (72.8%) patients had normal EEG. At the 18-month evaluation all patients were seizure free and 10 patients (83.3%) showed a complete normalization of EEG abnormalities. Discussion ,, Monotherapy with LEV was effective and well tolerated in patients with COE-G. Nevertheless, prospective, large, long-term double-blind studies are needed to confirm these findings. [source] Comparison of apomorphine and levodopa infusions in four patients with Parkinson's disease with symptom fluctuationsACTA NEUROLOGICA SCANDINAVICA, Issue 5 2009D. Nyholm Background,,, Motor fluctuations in patients with advanced Parkinson's disease may be successfully treated with subcutaneous apomorphine infusion or intraduodenal levodopa/carbidopa infusion. No comparative trials of these two alternatives were performed. Aims of the study,,, We present a subanalysis from a randomized crossover clinical trial where levodopa infusion as monotherapy was compared with any other combination of pharmacotherapy in fluctuating patients. Four patients used apomorphine infusion and oral levodopa in the comparator arm. The results of these four patients are presented in detail. Methods,,, The duration of the trial was 3 + 3 weeks. Patients were video-recorded half-hourly on two non-consecutive days of both treatment arms. Blinded video ratings were used. Patient self-assessments of motor function and quality-of-life (QoL) parameters were captured using an electronic diary. Results,,, Ratings in moderate to severe ,off' state ranged 0,44% on apomorphine infusion and 0,6% on levodopa infusion. Moderate to severe dyskinesias were not recorded in any of the treatments. QoL was reported to be improved in all patients on duodenal levodopa infusion. Conclusions,,, Monotherapy with duodenal infusion of levodopa was more efficacious and brought greater QoL than combination therapy with apomorphine infusion in these fluctuating patients. [source] Antiplatelet therapy after endovascular intervention: Does combination therapy really work and what is the optimum duration of therapy?,,CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue S1 2009Richard V. Milani MD Abstract The number of patients undergoing peripheral interventions has increased in recent years, highlighting the need for a safe and effective protective antithrombotic therapy. Platelet inhibition following coronary intervention is associated with a significantly reduced risk of graft occlusion, and has been acknowledged to be safe and effective in patients with peripheral arterial disease. Monotherapy with either aspirin or clopidogrel, reduces the rate of stroke, myocardial infarction, and cardiovascular death in patients suffering from peripheral arterial disease. Limited data from clinical trials investigating combination therapy of aspirin with ticlopidine or clopidogrel in patients undergoing endovascular interventions, have suggested the potential for a reduction in cardiovascular events. Nevertheless, the optimal duration of postintervention antiplatelet therapy remains to be defined. © 2009 Wiley-Liss, Inc. [source] Vildagliptin plus metformin combination therapy provides superior glycaemic control to individual monotherapy in treatment-naive patients with type 2 diabetes mellitusDIABETES OBESITY & METABOLISM, Issue 5 2009E. Bosi Aim:, To compare the efficacy and safety of vildagliptin and metformin initial combination therapy with individual monotherapies in treatment-naive patients with type 2 diabetes mellitus (T2DM). Methods:, This was a 24-week, randomized, double-blind, active-controlled study. Treatment-naive patients with T2DM who had a glycated haemoglobin (HbA1c) of 7.5,11% (N = 1179) were randomized equally to receive vildagliptin plus high-dose metformin combination therapy (50 mg + 1000 mg twice daily), vildagliptin plus low-dose metformin combination therapy (50 mg + 500 mg twice daily), vildagliptin monotherapy (50 mg twice daily) or high-dose metformin monotherapy (1000 mg twice daily). The primary objective was to demonstrate that HbA1c reduction from baseline with either combination therapy is superior to both monotherapies at the week 24 endpoint. Patients who failed glycaemic-screening criteria [HbA1c >11% or fasting plasma glucose (FPG) >15 mmol/l (270 mg/dl)] could enter a 24-week, single-arm substudy. These patients (N = 94) received open-label vildagliptin plus high-dose metformin combination therapy (100 mg + 1000 mg twice daily). Results:, From comparable baseline values (8.6,8.7%), HbA1c decreased in all four treatment groups, to the greatest extent with vildagliptin plus high-dose metformin combination therapy. Mean (SE) HbA1c change from baseline was ,1.8% (0.06%), ,1.6% (0.06%), ,1.1% (0.06%) and ,1.4% (0.06%) with vildagliptin plus high-dose metformin combination therapy, vildagliptin plus low-dose metformin combination therapy, and vildagliptin and metformin monotherapies respectively. The between-group difference was superior with vildagliptin plus high-dose metformin combination therapy (p < 0.001 vs. both monotherapies) and vildagliptin plus low-dose metformin combination therapy (p < 0.001 and p = 0.004, vs. vildagliptin and metformin monotherapies, respectively). Higher baseline HbA1c values were linked to greater HbA1c reductions, with changes of ,3.2% (0.22%), ,2.7% (0.22%), ,1.5% (0.24%) and ,2.6% (0.26%) respectively, occurring in patients with baseline HbA1c,10%. Reductions in FPG were superior with vildagliptin plus high-dose metformin combination therapy [change from baseline ,2.63 (0.13) mmol/l] compared with both monotherapies [,1.26 (0.13) mmol/l and ,1.92 (0.13) mmol/l, respectively; p < 0.001]. There was no incidence of hypoglycaemia or severe hypoglycaemia with either combination therapy, and neither was associated with weight gain. All treatments were well tolerated and displayed a comparable incidence of adverse events overall. Despite superior HbA1c lowering, the vildagliptin plus low-dose metformin combination therapy group demonstrated a favourable gastrointestinal (GI) tolerability profile compared with metformin monotherapy. Conclusions:, In treatment-naive patients, combinations of vildagliptin and both high-dose and low-dose metformin provide superior efficacy to monotherapy treatments with a comparable overall tolerability profile and low risk of hypoglycaemia. The potential dose-sparing effect of adding vildagliptin to low-dose metformin in preference to the up-titration of metformin may allow patients to achieve equivalent or superior HbA1c lowering without the GI tolerability issues associated with higher doses of metformin.

Marre Abstract Aims To evaluate the efficacy and safety of two dosage strengths of a single-tablet metformin,glibenclamide (glyburide) combination, compared with the respective monotherapies, in patients with Type 2 diabetes mellitus (DM) inadequately controlled by metformin monotherapy. Methods In this 16-week, double-blind, multicentre, parallel-group trial, 411 patients were randomized to receive metformin 500 mg, glibenclamide 5 mg, metformin,glibenclamide 500 mg/2.5 mg or metformin,glibenclamide 500 mg/5 mg, titrated with the intention to achieve fasting plasma glucose (FPG) , 7 mmol/l. Results Decreases in glycated haemoglobin (HbA1c) and FPG were greater (P < 0.05) for metformin,glibenclamide 500 mg/2.5 mg (,1.20% and ,2.62 mmol/l) and 500 mg/5 mg (,0.91% and ,2.34 mmol/l), compared with metformin (,0.19% and ,0.57 mmol/l) or glibenclamide (,0.33% and ,0.73 mmol/l). HbA1c < 7% was achieved by 75% and 64% of patients receiving metformin,glibenclamide 500 mg/2.5 mg and 500 mg/5 mg, respectively, compared with 42% for glibenclamide and 38% for metformin (P = 0.001). These benefits were achieved at lower mean doses of metformin or glibenclamide with metformin,glibenclamide 500 mg/2.5 mg and 500 mg/5 mg (1225 mg/6.1 mg and 1170 mg/11.7 mg) than with glibenclamide (13.4 mg) or metformin (1660 mg). Treatment-related serious adverse events occurred in two patients receiving glibenclamide. Plasma lipid profiles were unaffected and mean changes in body weight were , 1.0 kg. Conclusions Intensive management of Type 2 DM with a new metformin,glibenclamide combination tablet improved glycaemic control and facilitated the attainment of glycaemic targets at lower doses of metformin or glibenclamide compared with the respective monotherapies, without compromising tolerability. Diabet. Med. 19, 673,680 (2002) [source] Differential time effect profiles of amlodipine, as compared to valsartan, revealed by ambulatory blood pressure monitoring, self blood pressure measurements and dose omission protocolFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 4 2004Anca Radauceanu Abstract Amlodipine and valsartan are once-daily antihypertensive agents. To date, no comparison between these agents given as monotherapies was reported. This study was aimed to evaluate the therapeutic coverage and safety of amlodipine and valsartan in mild-to-moderate hypertensive patients. Multicenter, double-blind, randomized, comparative study. After a 4-week placebo wash-out period, 246 outpatients with office diastolic blood pressure 95 , DBP ,110 mmHg and systolic blood pressure (SBP) < 180 mmHg, in addition to a mean daytime SBP and/or DBP > 135/85 mmHg on 24-h ambulatory blood pressure monitoring (ABPM), were randomly allocated to once-daily amlodipine 5,10 mg or valsartan 40,80 mg, for 12 weeks. In a subgroup of patients, 48-h ABPM were performed at the end of the treatment period. Dose omission was simulated by a single-blind placebo dosing. The primary efficacy end-point was the 24-h trough office BP after 12 weeks of active therapy. The reductions in 24-h trough BP were more pronounced in amlodipine compared with valsartan group as well in office [SBP: ,17.8 ± 10.9 vs. ,14.6 ± 11.2, P = 0.025, DBP: ,12.7 ± 7.2 vs. ,10.9 ± 7.8 mmHg, P = 0.06) as in ambulatory BP (SBP/DBP: ,13.0 ± 13.7/,10.8 ± 9.1 vs. ,7.2 ± 19.4/,4.9 ± 13.4 mmHg, P < 0.05). Forty-eight hours after the last active dose, the slope of the morning BP surge (4,9 h) was less steep with amlodipine vs. valsartan [DBP (P < 0.04), SBP (n.s.)]. Ankle edema were more often reported in amlodipine group. These results suggest a superior BP lowering and a longer duration of action with amlodipine compared with valsartan. [source] Antimalarial drug quality in AfricaJOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 5 2007A. A. Amin PhD Abstract Background and objective: There are several reports of sub-standard and counterfeit antimalarial drugs circulating in the markets of developing countries; we aimed to review the literature for the African continent. Methods: A search was conducted in PubMed in English using the medical subject headings (MeSH) terms: ,Antimalarials/analysis'[MeSH] OR ,Antimalarials/standards'[MeSH] AND ,Africa'[MeSH]' to include articles published up to and including 26 February 2007. Data were augmented with reports on the quality of antimalarial drugs in Africa obtained from colleagues in the World Health Organization. We summarized the data under the following themes: content and dissolution; relative bioavailability of antimalarial products; antimalarial stability and shelf life; general tests on pharmaceutical dosage forms; and the presence of degradation or unidentifiable impurities in formulations. Results and discussion: The search yielded 21 relevant peer-reviewed articles and three reports on the quality of antimalarial drugs in Africa. The literature was varied in the quality and breadth of data presented, with most bioavailability studies poorly designed and executed. The review highlights the common finding in drug quality studies that (i) most antimalarial products pass the basic tests for pharmaceutical dosage forms, such as the uniformity of weight for tablets, (ii) most antimalarial drugs pass the content test and (iii) in vitro product dissolution is the main problem area where most drugs fail to meet required pharmacopoeial specifications, especially with regard to sulfadoxine,pyrimethamine products. In addition, there are worryingly high quality failure rates for artemisinin monotherapies such as dihydroartemisinin (DHA); for instance all five DHA sampled products in one study in Nairobi, Kenya, were reported to have failed the requisite tests. Conclusions: There is an urgent need to strengthen pharmaceutical management systems such as post-marketing surveillance and the broader health systems in Africa to ensure populations in the continent have access to antimalarial drugs that are safe, of the highest quality standards and that retain their integrity throughout the distribution chain through adequate enforcement of existing legislation and enactment of new ones if necessary, and provision of the necessary resources for drug quality assurance. [source] Results from different patient populations using combined therapy with alprostadil and sildenafil: predictors of satisfactionBJU INTERNATIONAL, Issue 4 2000J.H. Mydlo Objective To evaluate the outcome of combined therapy (using intraurethral alprostadil and oral sildenafil) in private and clinic patients with erectile dysfunction, and thus assess predictors of satisfaction. Patients and methods In all, 360 men were treated for erectile dysfunction using single and/or combined therapy, comprising 214 private-practice and 166 clinic patients. Responses were evaluated using the International Index for Erectile Function (IIEF) questionnaire before and after treatment. Serum testosterone levels, education and socio-economic status were also assessed. Group 1a consisted of 33 private patients and Group 1b of 24 clinic patients who tried the maximum dose of intraurethral alprostadil monotherapy initially, followed by the maximum dose of sildenafil monotherapy, and remained dissatisfied. Group 2a consisted of 32 private patients and group 2b of 31 clinic patients who tried the maximum dose of sildenafil monotherapy initially, followed by the maximum dose of alprostadil monotherapy, and were also dissatisfied. These two groups of 65 private and 55 clinic patients then underwent combined therapy. Results The mean ( sd) score for erectile function was 24.1 (2) for combined therapy (a 123% improvement), and 19.8 (1.8) (83% improvement) and 15.2 (1.6) (41% improvement) for sildenafil and alprostadil monotherapies (P < 0.05 for both patient groups). The men also reported an improvement in their satisfaction with intercourse. However, at 18 months, 60 of the 65 private patients but only 40 of the 55 clinic patients continued with combined therapy; thus, the discontinuation rate was three times greater among clinic than among private patients. Furthermore, the private patients had an overall improvement in the satisfaction score of 128%, compared with 51% for the clinic patients. Conclusion Although there were no significant differences in erectile function improvement within the two satisfied combined therapy groups, the differences in overall satisfaction and long-term withdrawal rates suggests that other factors beside motivation must be involved for success, e.g. education, persistence, realistic expectations, and certain psychological factors. Combined therapy should be considered for those patients who have a suboptimal response to monotherapy and refuse or are not candidates for surgical options. Generally, those patients with a higher education, greater persistence and more realistic expectations were more satisfied with combined therapy.

[source] Effects of combined inhibition of the Na+,H+ exchanger and angiotensin-converting enzyme in rats with congestive heart failure after myocardial infarctionBRITISH JOURNAL OF PHARMACOLOGY, Issue 5 2005Hartmut Ruetten We investigated the single vs the combined long-term inhibition of Na+,H+ exchanger-1 (NHE-1) and ACE in rats with congestive heart failure induced by myocardial infarction (MI). Rats with MI were randomized to receive either placebo, cariporide (3000 p.p.m. via chow), ramipril (1 mg kg,1 day,1via drinking water) or their combination for 18 weeks starting on day 3 after surgery. Cardiac morphology and function was assessed by echocardiography and by means of a 2.0 F conductance catheter to determine left ventricular (LV) pressure volume relationships. MI for 18 weeks resulted in an increase in LV end-diastolic diameter (LVDed) in the placebo-treated group when compared to sham (placebo: 1.1±0.04 cm; sham: 0.86±0.01; P<0.05). Combined inhibition of NHE-1 and ACE, but not the monotherapies, significantly reduced LVDed (1.02±0.02 cm). Preload recruitable stroke work (PRSW), dp/dtmax (parameter of systolic function) and end-diastolic pressure volume relationship (EDPVR, diastolic function) were significantly impaired in placebo-treated MI group (PRSW: 39±7 mmHg; dp/dtmax: 5185±363 mmHg s,1; EDPVR: 0.042±0.001 mmHg ,l,1; all P<0.05). Cariporide treatment significantly improved PRSW (64±7 mmHg), dp/dtmax (8077±525 mmHg s,1) and EDPVR (0.026±0.014 mmHg ,l,1), and reduced cardiac hypertrophy in rats with MI. Combined inhibition of NHE-1 and ACE had even a more pronounced effect on PRSW (72±5 mmHg) and EDPVR (0.026±0.014 mmHg ,l,1), as well as cardiac hypertrophy that, however, did not reach statistical significance compared to cariporide treatment alone. The NHE-1 inhibitor cariporide significantly improved LV remodeling and function in rats with congestive heart failure induced by MI. The effect of cariporide was comparable or tended to be stronger (e.g. systolic function) compared to ramipril. Combined treatment with cariporide and ramipril tended to be more effective on LV remodeling in rats with heart failure than the single treatments. Thus, inhibition of the NHE-1 may be a promising novel therapeutic approach for the treatment of congestive heart failure.

Mcgill M.D. Abstract Background: Hydrochlorothiazide (HCTZ) is commonly used to treat black patients with hypertension. To avoid the metabolic disturbances associated with high-dose HCTZ, blood pressure control may be achieved by combining low doses with another antihypertensive. Hypothesis: The study was undertaken to assess the tolerability and antihypertensive dose-response efficacy of telmisartan and HCTZ and their combination in black patients with mild to moderate hypertension (mean supine blood pressure 140/95-200/114 mmHg). Methods: Following a 4,week, single-blind, placebo run-in period, 222 black patients were randomized to once-daily treatment with one of 20 different double-blind combinations of telmisartan (0, 20, 40, 80, 160 mg) and HCTZ (0, 6.25, 12.5, 25 mg) for 8 weeks. Blood pressure was measured at baseline and after 2, 4, and 8 weeks. Results: Telmisartan 80 mg/HCTZ 12.5 mg reduced supine trough diastolic blood pressure (DBP),primary efficacy parameter,by 13.3 mmHg, and supine trough systolic blood pressure (SBP) by 21.5 mmHg. These reductions represented benefits of 13.7/8.7 mmHg over telmisartan 80 mg and 12.3/8.1 mmHg over HCTZ 12.5 mg(p<0.01). Telmisartan 40 mg/HCTZ 12.5 mg reduced supine trough SBP/DBP by 14.3/10.0 mmHg, amounting to 12.3/3.3 mmHg more than telmisartan 40 mg and 5.1/4.8 mmHg more than HCTZ 12.5 mg, This reached significance for the comparisons with telmisartan 40 mg for SBP and HCTZ 12.5 mg for DBP (p,0.05). A response surface analysis and therapeutic response rates confirmed the additive antihypertensive effects of telmisartan and HCTZ. All treatments were well tolerated, with side-effect profiles comparable with placebo. Adverse events were mainly transient and of mild to moderate severity. Conclusions: Telmisartan 80 mg combined with HCTZ 12.5 mg is effective and well tolerated in black patients with mild to moderate hypertension, providing greater antihypertensive activity than the corresponding monotherapies. [source] Thalidomide for the treatment of multiple myelomaCONGENITAL ANOMALIES, Issue 3 2004Yutaka Hattori ABSTRACT Although thalidomide was withdrawn in the 1960s after its teratogenic property was recognized, it was subsequently found that this drug possesses immunomodulatory and anti-inflammatory effects. Recent studies have also demonstrated that thalidomide has antineoplastic activity via an antiangiogenic mechanism. Observations in the late 1990s that the microenvironment in the bone marrow plays a role in tumor progression in multiple myeloma provided an impetus to use thalidomide for the treatment of this disease. It is known that thalidomide monotherapy is effective in one-third of refractory cases, and in combination with glucocorticoids and/or antineoplastic drugs, thalidomide provides a response rate of more than 50%. Thus, thalidomide therapy is considered a standard approach for the treatment of relapsed and refractory myeloma. The exact mechanism of the antimyeloma effect of thalidomide is not yet clearly understood. Anti-angiogenic effects, direct activity in tumor cells such as the induction of apoptosis or G1 arrest of the cell cycle, the inhibition of growth factor production, the regulation of interactions between tumor and stromal cells, and the modulation of tumor immunity have been considered as possible mechanisms. In addition to its teratogenicity, the adverse effects of thalidomide have been general symptoms such as somnolence and headache, peripheral neuropathy, constipation, skin rash, and other symptoms. Although these adverse effects are generally reversible and mild, grade 3 and 4 toxicities such as peripheral neuropathy, deep venous thrombosis, neutropenia, and toxic dermal necrosis have occasionally been reported. The application of thalidomide therapy in patients with multiple myeloma is being broadened to include not only cases of refractory myeloma, but also previously untreated cases, as well as for maintenance therapy after hematopoietic stem cell transplantation and for the treatment of other hematological diseases. The safe use of this drug will depend on the establishment of diagnostic and treatment guidelines. In addition, the establishment of a nation-wide regulation system is urgently needed in Japan. [source] Atomoxetine treatment in adults with attention-deficit/hyperactivity disorder and comorbid social anxiety disorderDEPRESSION AND ANXIETY, Issue 3 2009Lenard A. Adler M.D. Abstract Background: To evaluate the effect of atomoxetine (ATX) on attention-deficit/hyperactivity disorder (ADHD) and comorbid social anxiety disorder in adults. Methods: Randomized, double-blind, placebo-controlled, conducted in adults with ADHD and social anxiety disorder. Patients received 40,100,mg ATX (n=224) or placebo (n=218) for 14 weeks following a 2-week placebo lead-in period. Efficacy measures included the Conners' Adult ADHD Rating Scale: Investigator-Rated: Screening Version (CAARS:Inv:SV), Liebowitz Social Anxiety Scale (LSAS), Clinical Global Impression-Overall-Severity (CGI-O-S), State-Trait Anxiety Inventory (STAI), Social Adjustment Scale-Self Report (SAS), and Adult ADHD Quality of Life Scale-29 (AAQoL). Safety and tolerability were also assessed. Results: ATX mean change (,8.7±10.0) from baseline (29.6±10.4) on CAARS:Inv:SV Total ADHD Symptoms score was significantly greater than placebo mean change (,5.6±10.2) from baseline (31.2±9.4; P<.001). ATX mean change (,22.9±25.3) from baseline (85.3±23.6) on LSAS Total score was significant compared to placebo mean change (,14.4±20.3) from baseline (82.1±21.3; P<.001). The visit-wise analysis revealed greater improvement on the CAARS:Inv:SV Total ADHD Symptoms score and LSAS Total score for ATX at every time point throughout the study (P values ,.012). Mean changes in CGI-O-S, STAI-Trait Anxiety scores, and AAQoL Total score were significantly greater for ATX compared to placebo. Mean change for both groups on STAI-State Anxiety scores was comparable. Improvement on SAS for ATX compared to placebo was not significant. Rates of insomnia, nausea, dry mouth, and dizziness were higher with ATX than with placebo. Discontinuation rates due to treatment-emergent adverse events were similar between groups. Conclusions: ATX monotherapy effectively improved symptoms of ADHD and comorbid social anxiety disorder in adults and was well tolerated. Depression and Anxiety, 2009. Published 2009 Wiley-Liss, Inc. [source] Clarithromycin-induced hypomania in a child , a case reportACTA PSYCHIATRICA SCANDINAVICA, Issue 3 2010W. J. Baranowski Baranowski WJ. Clarithromycin-induced hypomania in a child , a case report. Objective:, We report here a child developing hypomania while treated with clarithromycin. Method:, Case report. Results:, A 3-year-old boy was treated for pneumonia with oral clarithromycin in monotherapy. The boy became somewhat hyperactive and irritable after the second dose. After the third dose he presented with psychomotor agitation, pressured speech, irritability, aggressive behaviour and insomnia. The antibiotic was identified as the only possible cause of the described clinical picture and was discontinued immediately. The hypomanic symptoms subsided gradually over 36 h. Conclusion:, Commonly-used medications can produce uncommon adverse reactions. Clinicians, especially general practitioners, pediatricians, as well as child and adolescent psychiatrists ought to be aware of such a possibility when evaluating a child with suddenly changed behaviour. [source] Patients with a major depressive episode responding to treatment with repetitive transcranial magnetic stimulation (rTMS) are resistant to the effects of rapid tryptophan depletionDEPRESSION AND ANXIETY, Issue 8 2007John P. O'Reardon M.D. Abstract Repetitive transcranial magnetic stimulation (rTMS) appears to be efficacious in the treatment of major depression based on the results of controlled studies, but little is known about its antidepressant mechanism of action. Mood sensitivity following rapid tryptophan depletion (RTD) has been demonstrated in depressed patients responding to SSRI antidepressants and phototherapy, but not in responders to electroconvulsive therapy (ECT). We sought to study the effects of RTD in patients with major depression responding to a course of treatment with rTMS. Twelve subjects treated successfully with rTMS monotherapy underwent both RTD and sham depletion in a double-blind crossover design. Depressive symptoms were assessed using both a modified Hamilton Depression Rating Scale (HDRS) and Beck Depression Inventory (BDI). The differential change in depression scores across the procedures was compared. No significant difference in mood symptoms was noted between RTD and the sham-depletion procedure on either continuous measures of depression, or in the proportions of subjects that met predefined criteria for a significant degree of mood worsening. Responders to rTMS are resistant to the mood perturbing effects of RTD. This suggests that rTMS does not depend on the central availability of serotonin to exert antidepressant effects in major depression. Depression Anxiety 24:537,544, 2007. © 2006 Wiley-Liss, Inc.
