    Full Text Available Abstract Background Colorectal cancer is one of the major neoplasms and a leading cause of cancer death worldwide, and new preventive strategies are needed to lower the burden of this disease. Metformin, a biguanide, which is widely used for treating diabetes mellitus, has recently been suggestive to have a suppressive effect on tumorigenesis and cancer cell growth. In a previous study conducted in non-diabetic subjects, we showed that oral short-term low-dose metformin suppressed the development of colorectal aberrant crypt foci (ACF. ACF have been considered as a useful surrogate biomarker of CRC, although the biological significance of these lesions remains controversial. We devised a prospective randomized controlled trial to evaluate the chemopreventive effect of metformin against metachronous colorectal polyps and the safety of this drug in non-diabetic post-polypectomy patients. Methods/Design This study is a multi-center, double-blind, placebo-controlled, randomized controlled trial to be conducted in non-diabetic patients with a recent history of undergoing colorectal polypectomy. All adult patients visiting the Yokohama City University hospital or affiliated hospitals for polypectomy shall be recruited for the study. Eligible patients will then be allocated randomly into either one of two groups: the metformin group and the placebo group. Patients in the metformin group shall receive oral metformin at 250 mg per day, and those in the placebo group shall receive an oral placebo tablet. At the end of 1 year of administration of metformin/placebo, colonoscopy will be performed to evaluate the polyp formation. Discussion This is the first study proposed to explore the effect of metformin against colorectal polyp formation. Metformin activates AMPK, which inhibits the mammalian target of rapamycin (mTOR pathway. The mTOR pathway plays an important role in the cellular protein translational machinery and cell proliferation. Patients with

    Background New tools are required for the diagnosis of pre-symptomatic leprosy towards further reduction of disease burden and its associated reactions. To address this need, two new skin test antigens were developed to assess safety and efficacy in human trials. Methods A Phase I safety trial was first conducted in a non-endemic region for leprosy (U.S.A.). Healthy non-exposed subjects (n = 10) received three titrated doses (2.5 µg, 1.0 µg and 0.1 µg) of MLSA-LAM (n = 5) or MLCwA (n = 5) and control antigens [Rees MLSA (1.0 µg) and saline]. A randomized double blind Phase II safety and efficacy trial followed in an endemic region for leprosy (Nepal), but involved only the 1.0 µg (high dose) and 0.1 µg (low dose) of each antigen; Tuberculin PPD served as a control antigen. This Phase II safety and efficacy trial consisted of three Stages: Stage A and B studies were an expansion of Phase I involving 10 and 90 subjects respectively, and Stage C was then conducted in two parts (high dose and low dose), each enrolling 80 participants: 20 borderline lepromatous/lepromatous (BL/LL) leprosy patients, 20 borderline tuberculoid/tuberculoid (BT/TT) leprosy patients, 20 household contacts of leprosy patients (HC), and 20 tuberculosis (TB) patients. The primary outcome measure for the skin test was delayed type hypersensitivity induration. Findings In the small Phase I safety trial, reactions were primarily against the 2.5 µg dose of both antigens and Rees control antigen, which were then excluded from subsequent studies. In the Phase II, Stage A/B ramped-up safety study, 26% of subjects (13 of 50) showed induration against the high dose of each antigen, and 4% (2 of 50) reacted to the low dose of MLSA-LAM. Phase II, Stage C safety and initial efficacy trial showed that both antigens at the low dose exhibited low sensitivity at 20% and 25% in BT/TT leprosy patients, but high specificity at 100% and 95% compared to TB patients. The high dose of both antigens

    Full Text Available Objective: This study was undertaken to explore the efficacy and safety of Citrus sudachi peel for metabolic risk factors in obese male and female adults. Background: Citrus sudachi Hort. ex Shirai (Rutaceae, called “sudachi”, is a small, round, green citrus fruit that is mainly cultivated in Tokushima Prefecture in Japan. Our group reported that Citrus sudachi peel powder improved glucose tolerance and dyslipidemia in Zucher-fatty rats and reduced hyperglycemia and hypertriglyceridemia in GK diabetic rats. Materials and Methods: We conducted a randomized, double-blind, placebo-controlled trial in 40 participants with abdominal obesity and metabolic risk factors including hypertension, impaired glucose tolerance and elevated triglyceride levels. Participants were randomized to receive either tablets that contained 1.3 g dried Citrus sudachi peel powder or placebo tablets for 12 weeks. The sudachi peel group included 14 males and 5 females with a mean age of 54.5 years, and the placebo group included 18 males and 2 females with a mean age of 51.9 years. Results: Physical status including body weight, waist circumference and blood pressure and laboratory markers including metabolic parameters were not different at any observation point between the two groups. However, among participants with serum triglyceride levels of more than 120 mg/dl, body weight, waist circumference and serum triglyceride levels were significantly decreased at several observation points after the start of treatment in the sudachi peel group but not in the placebo group. No serious adverse events were observed in the sudachi peel group. Conclusions: Citrus sudachi peel has the potential effect to safely improve abdominal obesity and lower serum levels of TG in obese individuals with hypertriglyceridemia. A large-scale randomized, double-blind clinical study targeting subjects with both abdominal obesity and high TG levels is needed to confirm the metabolic effects of

    To evaluate the efficacy, safety and tolerability of Tibolone use during the menopausal transition (MT). Sixty-five healthy women aged 40-55 years (48.5 ± 3.5 years) were recruited for a randomized, double-blind controlled trial. Thirty participants were recruited to receive oral Tibolone 2.5 mg/day - Tibolone Group (TG), and 35 participants were assigned to the Placebo Group (PG), which received one capsule of lactose/day. Both groups were treated for 12 consecutive weeks. The Blatt-Kupperman Menopausal Index (KMI) and the Greene Climacteric Scale (GCS) were used. The glycaemic and lipid profiles, biochemical measures of hepatic function and endometrial thickness were measured for safety. A daily registry of complaints related to the treatment was maintained, and anthropometric measures were obtained to assess tolerability. A total of 57 women completed the study. After 12 weeks of Tibolone use, the total score and percentage of the KMI and GCS were significantly decreased compared to baseline, which reflected the efficacy of the treatment of climacteric symptoms. The improvement in blood biochemistry, endometrial atrophy and maintenance of the anthropometrical measures reflected the safety of Tibolone use. The absence of serious side effects demonstrated good tolerability for Tibolone use. The results showed good efficacy, tolerability and safety of Tibolone use during the MT.

    To assess the efficacy and safety of human placenta extract in the relief of climacteric symptoms. A prospective, randomized, double-blind, placebo-controlled trial was performed on 108 women with menopausal symptoms. Human placenta extract or placebo was administered to the women for 4 weeks. Climacteric symptoms were assessed with the Kupperman Index (KMI). Both groups showed a significant reduction in the KMI score at the end of treatment. However, the decrease in the KMI score was significantly greater in the product group than in the placebo group (-12.30 +/- 10.44 vs -7.15 +/- 9.11, P = 0.012) after 4 weeks of treatment. The level of lipid profiles and liver function tests demonstrated no significant changes before and after treatment in both groups. Human placenta extract reduced climacteric symptoms more than the placebo. The safety evaluation showed a good safety and tolerability profile in the placenta extract group. The results of the present study suggest that human placenta extract can be an alternative therapy in women with menopausal symptoms.

    Impetigo is a common skin infection, primarily caused by Staphylococcus aureus and mainly occurring in children. It is usually treated topically with antibiotics to achieve a quick cure and prevent spread of the infection. Worldwide, resistance rates of S. aureus against commonly used antibiotics are rising. Retapamulin belongs to a newly developed class of antibiotics for the treatment of uncomplicated skin infections. Our aim was to compare the efficacy and safety of topical application of retapamulin ointment with topical placebo ointment in the treatment of primary impetigo. In a randomized, double-blind, multicentre study, patients received either topical retapamulin ointment 1% twice daily for 5 days or topical placebo. Patients were enrolled into the study for 14 days and attended the clinic for three visits during which clinical and laboratory evaluations were performed. Two hundred and thirteen patients were randomized, with 139 evaluable patients in the retapamulin group and 71 in the placebo group. Based on the primary efficacy endpoint of clinical response after 7 days (intention to treat), retapamulin ointment was superior to placebo (success rate 85.6% vs. 52.1%; Pimpetigo, offering a new treatment option.

    Subclinical hypothyroidism, a thyroid disorder without obvious symptoms of thyroid deficiency, occurs in 3%-8% of the global population. Ashwagandha [Withania somnifera (L.) Dunal], a traditional medicine in Ayurveda, is often prescribed for thyroid dysfunctions. This pilot study was designed to evaluate the efficacy and safety of ashwagandha root extract in subclinical hypothyroid patients. A prospective, randomized, double-blind, single-center placebo-controlled study was performed at Sudbhawana Hospital, Varanasi, India between May 2016 and September 2016. Fifty subjects with elevated serum thyroid stimulating hormone (TSH) levels (4.5-10 μIU/L) aged between 18 and 50 were randomized in either treatment (n = 25) or placebo (n = 25) groups for an 8-week treatment period. Ashwagandha root extract (600 mg daily) or starch as placebo. Efficacy Variables: Serum TSH, serum triiodothyronine (T3), and thyroxine (T4) levels. A total of four subjects (two from each group) withdrew their consent before the second visit. Eight weeks of treatment with ashwagandha improved serum TSH (p Ashwagandha treatment effectively normalized the serum thyroid indices during the 8-week treatment period in a significant manner (time-effects: TSH [p ashwagandha: 1[4%]; Placebo: 3[12%]) out of 50 reported few mild and temporary adverse effects during this study. Treatment with ashwagandha may be beneficial for normalizing thyroid indices in subclinical hypothyroid patients.

    In Traditional Iranian Medicine (TIM), Melissa officinalis L. is commonly regarded as an effective therapy for heart palpitations. Heart palpitation is a common complaint that is often benign and associated with a marked distress that makes the condition difficult to treat. Herbal medicines provide an alternative to conventional drugs for treating various kinds of diseases. This study was done as a double blind randomized placebo-controlled clinical trial to evaluate the efficacy and safety of the dried extract of M. officinalis on adults suffering from benign palpitations. Eligible volunteers were randomly assigned as outpatients to a 14 day treatment with 500 mg twice a day of lyophilized aqueous extract of M. officinalis leaves (or placebo). Participants in the tests, physicians and researchers were blind to group assignments. Both primary and secondary outcomes were patient-reported. Primary outcomes were obtained from two measures: mean frequency of palpitation episodes per week, derived from patients׳ diaries, and mean intensity of palpitation estimated through Visual Analogue Scale (VAS) in a self-report questionnaire. Psychiatric symptoms (somatization, anxiety and insomnia, social dysfunction and severe depression) were evaluated as secondary outcomes by General Health Questionnaire-28 (GHQ-28), before and after intervention. Fifty-five volunteers out of 71 recruited study subjects completed the trial. Results showed that 14-day of treatment with lyophilized aqueous extract of M. officinalis leaves reduced frequency of palpitation episodes and significantly reduced the number of anxious patients in comparison to the placebo (P=0.0001, P=0.004 resp.). Also, M. officinalis extract showed no indication of any serious side effects. Lyophilized aqueous extract of M. officinalis leaves may be a proper and safe herbal drug for the treatment of benign palpitations. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    UR-1505 is a new small molecule with immune modulator properties intended for the topical treatment of inflammatory skin diseases that has shown anti-inflammatory effects in models of skin inflammation. We compared the activity of UR-1505 ointment against its vehicle in the treatment of atopic dermatitis. Secondary objectives included exploring dose response, safety, and local tolerability of UR-1505. Patients with AD lesions on 2 symmetrical topographic areas (arms, leg, or trunk) were included in this unicenter randomized, double-blind, within-patient, controlled Phase II exploratory trial and received simultaneously 2 different treatments (0.5%, 1%, or 2% UR-1505 and vehicle or 0.1% tacrolimus ointment) once daily during 28 days. The primary efficacy end point was the change from baseline in the Investigator Global Assessment score at Day 28. Secondary end points were percentage of area clearance, local Eczema Area Severity Index (local EASI), and local tolerability. A linear mixed model was used, fitting treatment, body side, and group (treatment at the contralateral side) as fixed factors and the patient as a random effect. Twenty-eight patients were randomized and 25 patients were included in the per protocol analysis, with 50 evaluable lesions (n = 13 for vehicle, n = 8 for UR-1505 0.5%, n = 9 for 1% UR-1505, n=8 for 2% UR-1505, and n=12 for tacrolimus). The mean Investigator Global Assessment score change from baseline at Day 28 was -1.7 for vehicle, -1.0, -1.2, and -1.5 for 0.5%, 1%, and 2% UR-1505, respectively, and -2.6% for tacrolimus (P = 0.002). No serious nor causal adverse reactions were reported in this study, but patients reported numerous local symptoms after product applications, especially itching, tingling, tightness, and heat/burning sensations at frequencies that were similar for vehicle, 1% UR-1505, and 2% UR-1505; more frequent with 0.5% UR-1505; and lowest for tacrolimus. This study found that UR-1505 may not be a suitable option for the

    Graying of hair-a sign of aging-raises cosmetic concerns. Individuals with gray hair often look older than others their age; therefore, some dye their hair for aesthetic purposes. However, hair colorants can induce many problems including skin irritation, allergic reaction and hair-breakage. This randomized, double-blind clinical trial was performed in order to examine the effects of APHG-1001, a compound including an extract from Pueraria lobata, on graying hair. A total of 44 female subjects were randomly treated with either APHG-1001 or placebo twice daily for 24 weeks. Using the phototrichogram analysis, a count of newly developed gray hair was estimated. Investigator assessment and subject self-assessment were also performed in order to evaluate the efficacy of the compound. The mean number of newly developed gray hair at 24 weeks was 6.3/cm(2) in the APHG-1001 group and 11.4/cm(2) in the placebo group; the difference was statistically significant (phair grayness by the end of the study. No severe adverse events in either group were observed. Moreover, the incidence of adverse events did not differ between the groups. This clinical trial revealed that APHG-1001, which contains an extract of P. lobata, could prevent the development of new gray hair without any remarkable adverse effects. Thus, it can be considered as a viable treatment option for the prevention of gray hair.

    To assess the efficacy and safety of lansoprazole in treating infants with symptoms attributed to gastroesophageal reflux disease (GERD) that have persisted despite a >or= 1-week course of nonpharmacologic management. This multicenter, double-blind, parallel-group study randomized infants with persisting symptoms attributed to GERD to treatment with lansoprazole or placebo for 4 weeks. Symptoms were tracked through daily diaries and weekly visits. Efficacy was defined primarily by a >or= 50% reduction in measures of feeding-related crying and secondarily by changes in other symptoms and global assessments. Safety was assessed based on the occurrence of adverse events (AEs) and clinical/laboratory data. Of the 216 infants screened, 162 met the inclusion/exclusion criteria and were randomized. Of those, 44/81 infants (54%) in each group were responders--identical for lansoprazole and placebo. No significant lansoprazole-placebo differences were detected in any secondary measures or analyses of efficacy. During double-blind treatment, 62% of lansoprazole-treated subjects experienced 1 or more treatment-emergent AEs, versus 46% of placebo recipients (P= .058). Serious AEs (SAEs), particularly lower respiratory tract infections, occurred in 12 infants, significantly more frequently in the lansoprazole group compared with the placebo group (10 vs 2; P= .032). This study detected no difference in efficacy between lansoprazole and placebo for symptoms attributed to GERD in infants age 1 to 12 months. SAEs, particularly lower respiratory tract infections, occurred more frequently with lansoprazole than with placebo.

    To compare the efficacy, safety, and cost-effectiveness of rupatadine and olopatadine in patients of allergic rhinitis (AR). A 2-week, single-centered, randomized, double-blind, parallel group comparative clinical study was conducted on patients with AR. Following inclusion and exclusion criteria, 67 patients were recruited and randomized to two treatment groups and received the respective drugs for 2 weeks. At follow-up, parameters assessed were total nasal symptom score (TNSS), change in total and differential count of eosinophil. In olopatadine group, there was a significantly higher reduction in TNSS (P rupatadine. Both the drugs significantly reduced the absolute eosinophil count, but olopatadine (P rupatadine group. Olopatadine is a better choice in AR in comparison to rupatadine due to its better efficacy and safety profile.

    To explore the hypothesis that nontouch therapy such as therapeutic touch (TT) reduces stress to a clinically important degree and is safe to use in preterm infants. A pilot randomized, double-blind, controlled trial. Two groups of 10 infants were enrolled and randomly assigned to treatment or nontreatment groups. Gestational age was less than 29 weeks. Demographic descriptions of the 2 groups were statistically similar. The observer and staff were blinded to assignment; the TT practitioner was blinded to observed measurements. Each infant received either TT or no therapeutic touch (NTT) for 5 minutes on 3 consecutive days at the same time of day, behind a curtain. Heart period variability (HPV) was measured 5 minutes before, during, and after the treatment phase. Examination of the parameters of oxygen saturation and episodes of apnea demonstrated no increase in adverse events in TT group compared with NTT group. Repeated-measures multivariate analysis of variance on HPV revealed differences in the interaction of group assignment with low-frequency, high-frequency, and low-to-high- frequency ratio interaction (F2,143 = 8.076, P = .000) and for group, day, and low-frequency, high-frequency, and low-to-high-frequency ratio (F2,288 = 3.146, P = .015), and in the posttreatment time period (F1,16 = 6.259, P = .024), reflective of greater parasympathetic activity in TT group. In this pilot trial, HPV showed an increase for the TT group compared with the NTT group. The study reveals no adverse effects of TT in preterm infants.

For RE, at week 24, the estimated Kaplan-Meier recurrence-free rates were 92.0%, 87.5%, and 82.7% in the E20, E10, and O10 groups, respectively. There was a statistically significant difference between the E20 and O10 groups (p=0.007). Drug-related adverse events tended to be mild but were reported at rates of 9.0%, 8.0%, and 5.3% in the E20, E10, and O10 groups, respectively. Compared with omeprazole, maintenance therapy with 20mg esomeprazole was generally well tolerated and effective for RE.

    To compare the efficacy and safety of generic (Utmos) and original (Actos) 30 mg Pioglitazone tablets. A multicenter, parallel randomized, double-blinded, controlled study. Type 2 diabetic patients, with glycosylated hemoglobin (HbA,) > or = 7.0%, who received Metformin not less than 1000 mg/day over three months were recruited. Patients were randomized to receive either generic or original Pioglitazone 30 mg/day for 24 weeks. Eighty-five patients were enrolled, forty-four patients received generic Pioglitazone andforty-one received original Pioglitazone. There were no significant differences in baseline characteristics between generic and original Pioglitazone group. There were significantly reduced HbA(1c), fasting plasma glucose (FPG) and significantly increased HDL-cholesterol from baseline (p 0.05). Generic Pioglitazone (Utmos) is effective in controlling blood glucose and has similar effects on lipid profile as the original one. Both generic (Utmos) and original (Actos) 30 mg Pioglitazone tablets were not different in the efficacy and safety profiles.

    Drug delivery systems capable of delivering free (unconjugated) curcuminoids is of great therapeutic significance, since the absorption of bioactive and permeable form plays a key factor in mediating the efficacy of a substance which undergoes rapid biotransformation. Considering the recent understanding on the relatively high bioactivities and blood-brain-barrier permeability of free curcuminoids over their conjugated metabolites, the present human study investigated the safety, antioxidant efficacy, and bioavailability of CurQfen (curcumagalactomannoside [CGM]), a food-grade formulation of natural curcumin with fenugreek dietary fiber that has shown to possess improved blood-brain-barrier permeability and tissue distribution in rats. In this randomized double-blinded and placebo-controlled trial, 60 subjects experiencing occupational stress-related anxiety and fatigue were randomized to receive CGM, standard curcumin, and placebo for 30 days (500 mg twice daily). The study demonstrated the safety, tolerance, and enhanced efficacy of CGM in comparison with unformulated standard curcumin. A significant improvement in the quality of life (P comparison of the free curcuminoids bioavailability after a single-dose (500 mg once per day) and repeated-dose (500 mg twice daily for 30 days) oral administration revealed enhanced absorption and improved pharmacokinetics of CGM upon both single- (30.7-fold) and repeated-dose (39.1-fold) administrations.

    Full Text Available Background. The purpose of this study was to investigate the clinical efficacy and safety of Benjakul (BJK extract for treating primary osteoarthritis (OA of the knee compared with diclofenac. Methods. A phase 2, double blind, randomized, and controlled study was conducted. The BJK group received 300 mg of BJK extract per day, while another group received 75 mg of diclofenac per day. All patients were followed up at 14 and 28 days. The changing of visual analogue scale (VAS for pain, 100-meter walking times, the modified Thai WOMAC index scores, and the global assessment were evaluated for efficacy. For safety issue, clinical signs and symptoms, complete physical examination, and renal and liver function were evaluated. Results. 39 and 38 patients for BJK extract group and diclofenac group were evaluated. For efficacy, all patients from both groups reported a decrease in the VAS pain score and 100-meter walking times but only the diclofenac group showed significant reduction of both measurements when compared with day 0. The modified Thai WOMAC scores of both groups were significantly reduced from baseline. However, all efficacy outcomes were not significantly different for both groups. For safety outcomes, the patients from both groups had no severe adverse events reported and only BJK had no toxicity in renal and liver functions. Conclusions. The BJK remedy extract showed equal clinical efficacy in relieving symptoms of OA knee when compared with diclofenac.

    Topical combination therapy containing a retinoid and an antimicrobial is an effective treatment for acne vulgaris. To evaluate the efficacy and safety of a new topical formulation containing clindamycin phosphate 1.2% and tretinoin 0.025% solubilized in an aqueous-based gel (CT gel). 1,649 participants were randomized 2:2:2:1 to 12 weeks of double-blind treatment with CT gel, clindamycin, tretinoin, or vehicle gel administered once daily. Significantly more participants achieved 2-grade or greater improvement on the Investigator's Static Global Assessment score with CT gel versus clindamycin, tretinoin, or vehicle gel. CT gel produced a significantly greater reduction in absolute number of total lesions versus all other treatment groups, in total and noninflammatory lesions versus clindamycin, and in total and inflammatory lesions versus tretinoin. Local tolerability was similar to that of tretinoin alone; signs and symptoms of irritation were most notable at week 2. There were no more adverse events with CT gel than with tretinoin gel. CT gel is more effective than clindamycin or tretinoin monotherapy, with a safety and tolerability profile similar to that of tretinoin.

    The mineralocorticoid receptor antagonist eplerenone improved clinical outcomes among patients with heart failure with reduced ejection faction (HFrEF) in the EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization And SurvIval Study in Heart Failure) study. However, similar efficacy and safety have not been established in Japanese patients. We evaluated the efficacy and safety of eplerenone in patients with HFrEF in a multicenter, randomized, double-blind placebo-controlled outcome study (ClinicalTrials.gov Identifier: NCT01115855). The aim of the study was to evaluate efficacy predefined as consistency of the primary endpoint with that of EMPHASIS-HF at a point estimate of HF. The primary endpoint occurred in 29.7% of patients in the eplerenone group vs. 32.7% in the placebo group [hazard ratio=0.85 (95% CI: 0.53-1.36)]. Hospitalization for any cause and changes in plasma BNP and LVEF were favorable with eplerenone. A total of 17 patients (15.3%) in the eplerenone group and 10 patients (9.1%) in the placebo group died. Adverse events, including hyperkalemia, were similar between the groups. Eplerenone was well-tolerated in Japanese patients with HFrEF and showed results consistent with those reported in the EMPHASIS-HF study.

    The purpose of this study was to evaluate the efficacy and safety of carbohydratederived fulvic acid (CHD-FA) in the treatment of eczema in patients two years and older. In this single-center, double-blind, placebo-controlled, parallel-group comparative study, 36 volunteers with predetermined eczema were randomly assigned to receive either the study drug or placebo twice daily for four weeks. All safety parameters remained within normal limits, with no significant differences in either group. Significant differences were observed for both severity and erythema in the placebo and CHD-FA treated groups, and a significant difference was observed for scaling in the placebo-treated group. With regard to the investigator assessment of global response to treatment, a significant improvement was observed in the CHD-FA group when compared with the placebo group. A statistically significant decrease in visual analog scale score was observed in both groups, when comparing the baseline with the final results. CHD-FA was well tolerated, with no difference in reported side effects other than a short-lived burning sensation on application. CHD-FA significantly improved some aspects of eczema. Investigator assessment of global response to treatment with CHD-FA was significantly better than that with emollient therapy alone. The results of this small exploratory study suggest that CHD-FA warrants further investigation in the treatment of eczema.

    Concomitant anticoagulant therapy may further reduce the risk of thrombotic events in patients with acute coronary syndrome (ACS) when given in addition to current standard antiplatelet therapies. This Phase II, randomized, double-blind, placebo-controlled study in Japanese patients with ACS assessed the bleeding risk of apixaban compared with placebo when given in combination with standard antiplatelet therapy, and followed a similar design to APPRAISE-1, the larger global Phase II study. Patients with recently diagnosed ACS were randomized to receive apixaban 2.5mg twice daily (BID; n=49), apixaban 5mg BID (n=50), or placebo (n=52) in addition to standard antiplatelet therapy for 24 weeks. The composite primary endpoint of major or clinically relevant nonmajor bleeding occurred in 2 patients (4.1%) in each apixaban treatment group and 1 patient (2.0%) in the placebo group, and a dose-dependent increase was seen in all bleeding events. No hemorrhagic strokes occurred in either apixaban treatment group. This study was terminated before completion because the APPRAISE-2 global Phase III trial was stopped based on the recommendation of the Data Monitoring Committee, following an increase in bleeding events without a counterbalancing reduction in ischemic events. The bleeding profile of apixaban in Japanese patients with ACS was similar to that found in the global APPRAISE-1 study, supporting the safety of apixaban in Japanese patients.

    Amphetamine is reported to enhance recovery after experimental stroke, but results from the first few trials in humans are inconclusive. Limited information is available on treatment safety. This study intended to investigate the safety and tolerability of dexamphetamine in patients with acute cerebral ischemia. Forty-five patients with cerebral ischemia were enrolled within 72 hours after onset of symptoms. Patients were randomized to 1 of 3 dose levels (2.5, 5, or 10 mg orally twice daily) or placebo for 5 consecutive days. Adverse events, blood pressure, heart rate, body temperature, consciousness level, and functional outcome measures were followed up daily during treatment. Follow-ups were made at day 7 and 1 and 3 months after stroke. Mean systolic and diastolic blood pressures and heart rate increased 14 mm Hg, 8 mm Hg, and 9 bpm, respectively, with dexamphetamine treatment compared with placebo (P< or =0.01). There was no difference between dexamphetamine and placebo regarding adverse events, body temperature, or consciousness level. During treatment, there was a benefit of dexamphetamine in neurological and functional outcome (P<0.05), but differences were not maintained at follow-up. Overall, dexamphetamine was safe and well tolerated by patients with acute cerebral ischemia, but blood pressure and heart rate increased during treatment in comparison to placebo. These observations may be important in the future planning of amphetamine trials because changes in these variables have been observed to interfere with clinical outcome. The suggestions of improvement in outcome must be confirmed in further studies.

    Type 2 lepra reaction (T2R) is a difficult-to-manage condition in leprosy, and an effective and safe steroid-sparing agent is needed for its management. The World Health Organization proposes clofazimine and recommends pentoxifylline for T2R. Our study was done to compare the effectiveness and safety of clofazimine and pentoxifylline therapy in patients with T2R. Twenty patients with T2R were randomized equally. Group A received pentoxifylline 400 mg t.d.s, group B received clofazimine 100 mg t.d.s. for 12 weeks. Both groups received prednisolone 40 mg o.d., tapered over 12 weeks. The effectiveness parameters were days needed for resolution of cutaneous and systemic manifestations, relapses, cutaneous score, systemic score, and average daily prednisolone intake. Safety parameters were spontaneously appearing adverse events and laboratory parameter changes. The cutaneous scores in the clofazimine (P < 0.001) and pentoxifylline groups (P < 0.001) showed a progressive decline in subsequent follow-ups. Individual follow-ups were significantly lower than baseline in both groups (P < 0.05). Systemic scores fared similarly. There were no significant intergroup changes. Average daily prednisolone intake progressively decreased in group B (P < 0.001). Cutaneous and systemic manifestations took a comparable time to resolve. Both drugs were safe. Pentoxifylline effectively reduces initial severity; clofazimine provides sustained improvement but acts slowly. © 2015 The International Society of Dermatology.

    Full Text Available Rectal microbicides are needed to reduce the risk of HIV acquisition associated with unprotected receptive anal intercourse. The MTN-007 study was designed to assess the safety (general and mucosal, adherence, and acceptability of a new reduced glycerin formulation of tenofovir 1% gel.Participants were randomized 1:1:1:1 to receive the reduced glycerin formulation of tenofovir 1% gel, a hydroxyethyl cellulose placebo gel, a 2% nonoxynol-9 gel, or no treatment. Each gel was administered as a single dose followed by 7 daily doses. Mucosal safety evaluation included histology, fecal calprotectin, epithelial sloughing, cytokine expression (mRNA and protein, microarrays, flow cytometry of mucosal T cell phenotype, and rectal microflora. Acceptability and adherence were determined by computer-administered questionnaires and interactive telephone response, respectively.Sixty-five participants (45 men and 20 women were recruited into the study. There were no significant differences between the numbers of ≥ Grade 2 adverse events across the arms of the study. Likelihood of future product use (acceptability was 87% (reduced glycerin formulation of tenofovir 1% gel, 93% (hydroxyethyl cellulose placebo gel, and 63% (nonoxynol-9 gel. Fecal calprotectin, rectal microflora, and epithelial sloughing did not differ by treatment arms during the study. Suggestive evidence of differences was seen in histology, mucosal gene expression, protein expression, and T cell phenotype. These changes were mostly confined to comparisons between the nonoxynol-9 gel and other study arms.The reduced glycerin formulation of tenofovir 1% gel was safe and well tolerated rectally and should be advanced to Phase 2 development.ClinicalTrials.gov NCT01232803.

    To study the efficacy and safety of Saccharomyces boulardii (SB) in acute childhood rotavirus diarrhea. Children (3 months to 5 years) with WHO-defined acute watery diarrhea and stool rotavirus positive (n  =  60) were randomized into intervention (n  =  30) and control (n  =  30) groups. The intervention group received SB (500 mg/day) for 5 days. The median duration (hours) of diarrhea was significantly shorter in the intervention group (60 vs. 89; 95% CI: -41.2 to - 16.8). A significantly shorter duration of hospitalization (74 vs. 91; 95% CI: -33.46 to - 0.54) was also seen in the intervention group, but no significant difference was seen for fever and vomiting. There was also no difference between the two groups in the proportion of children requiring parenteral rehydration and persistence of diarrhea lasting beyond day 7. There was no report of any adverse events. The present trial showed that SB is effective and safe in acute rotavirus diarrhea. © The Author [2016]. Published by Oxford University Press.

    Placebo controlled double-blinded, prospectively randomized clinical trial with 17 patients (11 verum, 5 placebo) for evaluation of cellulite treatment with Acoustic Wave Therapy, (AWT(®)) was performed. The patients were treated once a week for 7 weeks, a total of 8 treatments with the D-ACTOR(®) 200 by Storz Medical AG. Data were collected at baseline, before 8th treatment, at 1 month (follow-up 1) and at 3 months (follow-up 2) after the last treatment with a patients' questionnaire, weight control, measurement of circumference and standardized photography. Treatment progress was further documented using a specially designed 3D imaging system (SkinSCAN(3D), 3D-Shape GmbH) providing an objective measure of cellulite (primary efficacy criteria). Patient's questionnaire in the verum group revealed an improvement in number and depth of dimples, skin firmness and texture, in shape and in reduction of circumference. The overall result (of skin waviness, Sq and Sz, surface and volume of depressions and elevations, Vvv and Vmp) at two follow-up visits indicates a more than medium sized superiority (MW = 0.6706) and is statistically significant (pWei-Lachin = 0.0106). The placebo group revealed no statistical significance. No side effects were seen. This indicates the efficacy and safety of AWT(®) for patients with cellulite.

    Adenosine receptor stress agents for myocardial perfusion imaging (MPI) may cause A(2B) and/or A(3) receptor-mediated bronchoconstriction, of particular concern to physicians testing patients with asthma or chronic obstructive pulmonary disease (COPD). A Phase 4, randomized, double-blind study (NCT00862641) assessed the safety of the selective A(2A) receptor agonist, regadenoson, compared with placebo in subjects with asthma or COPD who represented likely candidates for MPI. Overall, 356 and 176 subjects with asthma and 316 and 151 subjects with COPD received regadenoson and placebo, respectively. The percentage of subjects experiencing a >15% decrease in FEV(1) from baseline to any assessment up to 24 hours post-baseline was not statistically significantly different between the regadenoson and the placebo groups in the asthma or COPD stratum. Dyspnea, the most frequent respiratory adverse event, occurred with higher incidence (P regadenoson group than the placebo group in the asthma (10.7% vs 1.1%) and COPD (18.0% vs 2.6%) strata. No subjects experienced severe bronchoconstriction, although the occurrence of such reactions with adenosine receptor agonists cannot be ruled out, such that caution is advised. This information may be helpful to physicians selecting a pharmacologic stress agent for MPI in patients with asthma or COPD.

    S-citalopram (escitalopram) is the very active moiety of citalopram. It has been shown in many studies to be an effective and safe antidepressant for treating major depressive disorder (MDD). The aim of our study was to compare the efficacy and safety of escitalopram vs citalopram in Chinese MDD patients. In the double-blind study, 240 MDD patients were randomly assigned to treatment for 6 weeks either with escitalopram (10-20 mg/d) or citalopram (20-40 mg/d). The primary efficacy measurement was the change of 17-item Hamilton Depression Rating Scale (HAMD-17) total score from baseline to the end of study. The secondary efficacy measurements were response and remission rates. The adverse events (AEs) were recorded by the investigator. Two hundred and three (85%) patients completed the trial. The average dose was 13.9 mg/d in the escitalopram group and 27.6 mg/d in the citalopram group. No significant differences were found between the two groups in the change in HAMD-17 total score, response, and remission rate. These results were similar in severe MDD patients. No significant differences were found between the two groups in AEs. No serious AEs were observed in this study. The study suggests that escitalopram 10-20 mg/d are as effective and safe as citalopram 20-40 mg/d in the short-term treatment for Chinese MDD patients.

    Sambucus ebulus L. (S. ebulus) has had long-standing application in Traditional Persian Medicine for joint pain and for a variety of bone and joint disorders. According to traditional use of S. ebulus and its relevant pharmacologic properties, this study was designed to evaluate the efficacy and short-term safety of topical use of S. ebulus in patients with knee osteoarthritis (OA). Seventy nine patients with knee OA were randomly enrolled in 2 parallel arms of a pilot randomized, double-blind, active-controlled clinical trial. The patients were treated by topical S. ebulus gel or 1% diclofenac gel, three times a day, as much as a fingertip unit for 4 weeks. Patients were assessed prior to enrollment and, then, 2 and 4 weeks subsequent to the intervention, in terms of scores of visual analogue scale (VAS) for self-grading of their knee joint pain, and according to 3 different domains of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Any observed adverse effects were also scrutinized. The mean values of WOMAC pain score, total WOMAC score and VAS score for pain of the S. ebulus group were significantly lower compared with the diclofenac group (P=0.004, P=0.04, and P<0.001, respectively). In addition, no serious adverse effect was reported. This pilot study showed that topical treatment with S. ebulus gel can be recommended for alleviating symptoms of patients with knee OA. However, longer trials involving larger samples size, are needed for achieving a comprehensive understanding about the efficacy and safety of S. ebulus in knee OA. Copyright © 2016.

    Intravenous iron therapy is a treatment option for iron deficient patients who are intolerant to oral iron or where oral iron is ineffective, but with possible adverse effects. Currently, prospective studies comparing different intravenous iron formulations are needed to determine safety and efficacy of these agents. We conducted a prospective, double-blind, randomized controlled trial (RCT) to assess the feasibility of a trial comparing the safety of high molecular weight intravenous iron dextran, Infufer®, with intravenous iron sucrose, Venofer®, in non-hemodialysis adult outpatients. Primary outcome was the occurrence of immediate severe drug reactions. We enrolled 143 patients in a one-year period. Overall, 45/143 (31.5 %) patients (20 iron dextran, 25 iron sucrose) developed 48 infusion reactions (14 immediate, 28 delayed, and 3 both). The risk of an immediate reaction was similar in both groups, 9/73 (12.3 %) iron dextran versus 8/70 (11.4 %) iron sucrose, RR = 0.93 (95 % CI; 0.38 to 2.27). The risk of a delayed reaction was significantly higher in the iron sucrose group 22/70 (31.4 %) versus the iron dextran group 9/73 (12.3 %), RR = 2.55 (95 % CI; 1.26 to 5.15; p = 0.0078). In this limited feasibility study, no major differences in immediate reactions were seen, but a significantly higher number of delayed reactions were seen in the iron sucrose group. Further, under our assumptions and design a full RCT to evaluate the safety of different intravenous iron preparations is not feasible. Future studies should consider modifying the clinical outcomes, utilize multiple centers, and consider other emerging parenteral iron formulations. (ClinicalTrials.gov NCT005936197 January 3, 2008).

Significant differences were observed for both severity and erythema in the placebo and CHD-FA treated groups, and a significant difference was observed for scaling in the placebo-treated group. With regard to the investigator assessment of global response to treatment, a significant improvement was observed in the CHD-FA group when compared with the placebo group. A statistically significant decrease in visual analog scale score was observed in both groups, when comparing the baseline with the final results.Conclusion: CHD-FA was well tolerated, with no difference in reported side effects other than a short-lived burning sensation on application. CHD-FA significantly improved some aspects of eczema. Investigator assessment of global response to treatment with CHD-FA was significantly better than that with emollient therapy alone. The results of this small exploratory study suggest that CHD-FA warrants further investigation in the treatment of eczema.Keywords: fulvic acid, eczema, anti-inflammatory, efficacy, safety

    This 8-week, randomized, double-blind, placebo-controlled study, conducted August 2010-May 2012 in the United States, evaluated the safety and efficacy of vortioxetine 10 mg and 15 mg in patients with major depressive disorder (MDD). The mechanism of action of vortioxetine is thought to be related to direct modulation of serotonin (5-HT) receptor activity and inhibition of the serotonin transporter. Adults aged 18-75 years with MDD (DSM-IV-TR) and Montgomery-Asberg Depression Rating Scale (MADRS) total score ≥ 26 were randomized (1:1:1) to receive vortioxetine 10 mg or 15 mg or placebo once daily, with the primary efficacy end point being change from baseline at week 8 in MADRS analyzed by mixed model for repeated measures. Adverse events were recorded during the study, suicidal ideation and behavior were assessed using the Columbia-Suicide Severity Rating Scale (C-SSRS), and sexual dysfunction was assessed using the Arizona Sexual Experience (ASEX) scale. Of the 1,111 subjects screened, 469 subjects were randomized: 160 to placebo, 157 to vortioxetine 10 mg, and 152 to vortioxetine 15 mg. Differences from placebo in the primary efficacy end point were not statistically significant for vortioxetine 10 mg or vortioxetine 15 mg. Nausea, headache, dry mouth, constipation, diarrhea, vomiting, dizziness, and flatulence were reported in ≥ 5% of subjects receiving vortioxetine. Discontinuation due to adverse events occurred in 7 subjects (4.4%) in the placebo group, 8 (5.2%) in the vortioxetine 10 mg group, and 12 (7.9%) in the vortioxetine 15 mg group. ASEX total scores were similar across groups. There were no clinically significant trends within or between treatment groups on the C-SSRS, laboratory values, electrocardiogram, or vital sign parameters. In this study, vortioxetine did not differ significantly from placebo on MADRS total score after 8 weeks of treatment in MDD subjects.

    Cell culture-derived influenza vaccines (CCIVs) have several important advantages over egg-based influenza vaccines, including shorter production time, better preservation of wild-type virus antigenicity and large-scale production capacity. A randomized, double-blind, phase 3 trial was undertaken to evaluate the immunogenicity and safety of a novel cell culture-derived inactivated, subunit, trivalent influenza vaccine (NBP607, SK Chemicals, Seongnam, Korea) compared to the control vaccine (AgrippalS1, Novartis Vaccines and Diagnostics Srl, Siena, Italy) among healthy adults aged 19 years or older (Clinical trial Number-NCT02344134). Immunogenicity was determined at pre-vaccination, 1 month and 6 month post-vaccination by the hemagglutination inhibition assay. Solicited and unsolicited adverse events were assessed after vaccination. A total of 1156 healthy subjects were recruited. NBP607 met all of the criteria of Committee for Medicinal Products for Human Use (CHMP) at 21 days post-vaccination. Contrary to NBP607, the control vaccine did not satisfy the seroconversion criteria for influenza B irrespective of age. Although the geometric mean titer for each influenza subtype declined gradually, seroprotection rate still remained ≥80% for all subtypes up to six month after NBP607 administration. NBP607 recipients met the seroprotection criteria for all three influenza subtypes up to 6 month post-vaccination. There was no significant difference in the occurrence of adverse events between the NBP607 and control groups. NBP607, a novel CCIV, showed excellent immunogenicity that lasted ≥6 months after vaccination and had tolerable safety profiles. In particular, NBP607 was more immunogenic against influenza B compared to the control, an egg-based subunit vaccine. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Secondary hyperparathyroidism (SHPT) is a frequent complication of chronic kidney disease. We evaluated AMG 416, a long-acting peptide agonist of the calcium-sensing receptor, to assess its safety, tolerability, and efficacy and to determine a safe and effective starting dose for subsequent phase 2 studies. The study was not designed to titrate AMG 416 dosing to achieve a specific PTH treatment goal. This is a multicenter, double-blind, randomized, placebo-controlled, dose-escalation study designed to evaluate the safety and efficacy of AMG 416 administered thrice weekly by IV bolus at the end of hemodialysis for up to 4 weeks. Eligible subjects were enrolled in one of three cohorts and treated with 5 mg of AMG 416 or placebo for 2 weeks (Cohort 1) or 5 or 10 mg of AMG 416 or placebo for 4 weeks (Cohorts 2 and 3). The primary endpoint was mean percentage change from baseline in PTH during the efficacy assessment phase (EAP) in Cohorts 2 and 3. Analysis of the primary endpoint showed that treatment with AMG 416 at 10 mg (Cohort 2) and 5 mg (Cohort 3) for up to 4 weeks resulted in mean 49.4% and 33.0% reductions from baseline in PTH during the efficacy assessment phase, respectively (p AMG 416 achieved PTH ≤300 pg/mL and ≥30% reduction in PTH from baseline in both cohorts. The observed decreases in serum-corrected calcium were well tolerated and serum phosphate levels also tended to decrease. The present clinical findings support the continued development of AMG 416 as a treatment for SHPT in hemodialysis patients.

    Background As of 2010, the rivastigmine patch was licensed for the treatment of Alzheimer's disease (AD) in 64 countries. Methods This 24-week, multicenter, randomized, double-blind, placebo-controlled study evaluated the efficacy, safety and tolerability of the 5-cm2 (9-mg loading dose; 4.6 mg/24 h delivery rate) and 10-cm2 (18-mg loading dose; 9.5 mg/24 h delivery rate) rivastigmine patch in Japanese patients with AD. Results In the primary analysis population (intent-to-treat last observation carried forward) at week 24, delayed deterioration was seen with the 10-cm2 patch versus placebo on the Japanese version of the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-J cog; p = 0.005) and the Japanese version of the Clinician's Interview-Based Impression of Change plus Caregiver Input (CIBIC plus-J; p = 0.067). Participants receiving the rivastigmine patch showed numerically less decline versus placebo at week 24 on the CIBIC plus-J, although this did not reach statistical significance. Statistical significance for the CIBIC plus-J was met following adjustment for body weight and baseline Mini-Mental State Examination score as dynamic allocation factors (p = 0.042) and on the Disability Assessment for Dementia (DAD; p = 0.024) and Mental Function Impairment (MENFIS; p = 0.016) subscales. Serious adverse events were rare and were consistent with the known safety profile of the rivastigmine patch. Conclusion: The rivastigmine patch has a favorable efficacy and tolerability profile in Japanese patients with AD. PMID:22163242

    Full Text Available Dietary supplementation is commonly employed by individuals seeking to improve body composition and exercise performance. The purpose of the present study was to examine the safety and effectiveness of a commercially available dietary supplement designed to promote thermogenesis and fat loss. In a randomized double-blind trial, participants were assigned to consume placebo or a multi-ingredient supplement containing caffeine, green tea extract, l-carnitine, evodiamine and other ingredients that purportedly enhance thermogenesis. The study included acute baseline testing, a 6-week progressive resistance training and supplementation intervention, and post-intervention testing. Laboratory assessments included resting energy expenditure responses to acute supplement ingestion, evaluation of body composition and muscular performance, and analysis of blood variables (metabolic panel, testosterone, estrogen and cortisol. Dependent variables were analyzed using ANOVA with repeated measures. No unfavorable effects of supplementation were reported, and the supplement did not adversely affect safety markers. However, the supplement did not reduce fat mass or increase lean mass relative to placebo. In the supplement group, lower body maximal strength was increased relative to placebo (+18%, d=1.1 vs. +10%, d=0.5, and cortisol concentrations were decreased relative to placebo (-16%; d=-0.4 vs. +15%, d=.75. However, no differences were observed for upper body maximal strength or muscular endurance. REE increased in response to both supplement and placebo ingestion (placebo: +5%; supplement: +11.5%, but the difference between conditions was not statistically significant. Overall, some select parameters may have been beneficially modified by supplementation, but this did not result in superior weight or fat loss over 6 weeks of supplementation and resistance training.

    We investigated the efficacy and safety of 50 and 75 μg desmopressin orally disintegrating tablets in men with nocturia (2 or more nocturnal voids). In this 3-month, randomized, double-blind, parallel study 50 and 75 μg desmopressin were compared with placebo. The co-primary efficacy end points were changes from baseline in mean number of nocturnal voids and proportions of patients achieving at least a 33% reduction from baseline in nocturnal voids (33% responders) during a 3-month treatment period. The full analysis set comprised 385 men (age range 20 to 87 years). The 50 and 75 μg doses significantly reduced the number of nocturnal voids (-0.37, p Desmopressin 50 and 75 μg increased the time to first void from baseline by approximately 40 minutes compared to placebo (p = 0.006 and p = 0.003, respectively). The response to desmopressin was seen by 1 week of treatment and was sustained. Significant increases in health related quality of life and sleep quality were observed compared to placebo. Desmopressin was well tolerated as only 2 subjects (age 74 and 79 years) on 50 μg had a serum sodium level of less than 130 mmol/L (vs 9 subjects on 75 μg). Desmopressin (orally disintegrating tablet) is an effective and well tolerated treatment for men with nocturia. Treatment with 50 μg desmopressin, the minimum effective dose, provided sustained improvement of nocturia throughout the study and meaningful benefits to patients with an improved safety profile.

    GABA-mediated sedatives have respiratory depressant properties that may be detrimental in patients with difficult airways. In this randomized, double-blind, multicenter, Phase IIIb Food and Drug Administration study, safety and efficacy of dexmedetomidine compared with placebo were evaluated as the primary sedative for awake fiberoptic intubation (AFOI). Patients were randomized to receive dexmedetomidine or saline. Patients were sedated with dexmedetomidine or rescue midazolam to achieve targeted sedation (Ramsay Sedation Scale ≥ 2) before topicalization and throughout AFOI. Primary efficacy endpoint was percentage of patients requiring rescue midazolam; secondary efficacy endpoints were total dose of rescue midazolam, percentage requiring additional rescue nonmidazolam medications, anesthesiologist's assessment of ease of subject care, and patient recall and satisfaction 24 hours postoperatively. Less rescue midazolam was required to maintain Ramsay Sedation Scale ≥2 (47.3% vs. 86.0%, P < 0.001), and supplemental midazolam dose was lower (1.07 ± 1.5 mg vs. 2.85 ± 3.0 mg, P < 0.001) with dexmedetomidine compared with placebo. More Mallampati Class IV patients treated with dexmedetomidine were successfully intubated without midazolam than with placebo (66.7% vs. 8.3%, P = 0.009). Dexmedetomidine decreased blood pressure and heart rate compared with placebo patients sedated with midazolam. Patients and anesthesiologists showed favorable satisfaction responses in both groups. Adverse events and patient recall were similar in both groups. Dexmedetomidine is effective as the primary sedative in patients undergoing AFOI. Some patients may require small supplemental doses of midazolam, in addition to dexmedetomidine, to achieve sufficient sedation for AFOI. Dexmedetomidine provides another AFOI option for sedation of patients with difficult airways.

    Cariprazine is an atypical antipsychotic currently under investigation as adjunctive therapy in patients with major depressive disorder (MDD) who have inadequate response to standard antidepressant therapy. A randomized, double-blind, placebo-controlled, flexible-dose study was conducted from December 2011 to December 2013 in adults who met DSM-IV-TR criteria for MDD and had an inadequate antidepressant response. Eligible patients were randomized to 8-week adjunctive treatment with placebo (n = 269), cariprazine 1-2 mg/d (n = 274), or cariprazine 2-4.5 mg/d (n = 276). The primary efficacy parameter was change from baseline to week 8 in Montgomery-Asberg Depression Rating Scale (MADRS) total score; P values were adjusted for multiple comparisons. Safety assessments included adverse events, clinical laboratory tests, vital signs, electrocardiograms (ECGs), and suicidality. Compared with placebo, reduction in MADRS total score at week 8 was significantly greater with adjunctive cariprazine 2-4.5 mg/d (least squares mean difference [LSMD] = -2.2; adjusted P = .0114), but not with cariprazine 1-2 mg/d (LSMD = -0.9; adjusted P = .2404). Significant LSMDs for MADRS total score change were detected at all earlier study visits (weeks 2, 4, 6) in the 2- to 4.5-mg/d group and at weeks 2 and 4 in the 1- to 2-mg/d group (all P values related adverse events were reported. These results show that adjunctive cariprazine 2-4.5 mg/d was effective and generally well tolerated in adults with MDD who had inadequate responses to standard antidepressants. Further clinical studies to confirm these results are warranted. ClinicalTrials.gov identifier: NCT01469377. © Copyright 2016 Physicians Postgraduate Press, Inc.

    The safety and tolerability of regadenoson, a pharmacologic stress agent that is excreted primarily by the kidneys, were examined in subjects with chronic kidney disease (CKD). This multicenter, double-blind, randomized, placebo-controlled study involved men and women, ≥18 years of age, with stage 3 or 4 [estimated glomerular filtration rate (eGFR) 30-59 mL/minute/1.73 m(2) and 15-29 mL/minute/1.73 m(2), respectively] CKD and known or suspected coronary artery disease. Subjects were randomized 2:1 to receive one 10-second intravenous injection of regadenoson 0.4 mg or placebo. The primary outcome measure was the frequency of serious adverse events over 24-h post-dose. The study included 432 subjects with stage 3 (regadenoson n = 287; placebo n = 145) and 72 with stage 4 (regadenoson n = 47; placebo n = 25) CKD. No serious adverse events or deaths were reported over 24-h post-dose.

    Blonanserin is a novel atypical antipsychotic agent with potent dopamine D(2) and serotonin 5-HT(2) antagonist properties. It may potentially have a lower incidence of adverse events than other antipsychotic agents. To determine the efficacy and safety of three doses of blonanserin compared with placebo and haloperidol in patients with acute-phase schizophrenia. This was a 6-week, randomized, double-blind, placebo- and haloperidol-controlled, international, multicentre study. Patients with an acute exacerbation of their schizophrenia, with a Positive and Negative Syndrome Scale (PANSS) score >/=70 and a Clinical Global Impression - Severity of Illness (CGI-S) score >/=4 ('moderately ill') [with no decrease >/=20% or >/=1 point, respectively, during the wash-out period] were randomized into one of five treatment groups (blonanserin 2.5, 5 or 10 mg, haloperidol 10 mg or placebo once daily). Patients were assessed weekly for clinical efficacy, adverse events, extrapyramidal symptoms (EPS) and drug compliance, and were assessed biweekly for other safety variables. All 307 randomized patients received at least one dose of study medication and 228 (74.3%) completed the study. The mean reduction in PANSS total score at week 6 was significantly greater with all active treatments compared with placebo (-12.58; p blonanserin 10 mg was significantly superior to blonanserin 2.5 mg (-30.18 vs -20.6; p blonanserin 5 mg (-27.19) and haloperidol 10 mg (-28.16) were not. All active treatments showed greater efficacy against the positive symptoms of schizophrenia, and blonanserin (5 and 10 mg) was more effective against the negative symptoms than haloperidol. Blonanserin was well tolerated at all doses and there was no evidence of clinically important weight gain, orthostatic hypotension, corrected QT interval prolongation or clinically relevant changes in laboratory test results. Haloperidol caused persistent elevation in prolactin levels, but this was not seen with any dose of

    Urticaria is a distressing condition associated with diverse clinical presentations. Chronic spontaneous urticaria (CsU) is characterized by wheals and angioedema. Its treatment requires an algorithmic approach to identify the optimum medication. Cetirizine is commonly used in the treatment of urticaria. Rupatadine is a selective non-sedating H1 -antihistamine approved for the treatment of CsU. This trial was conducted to ascertain whether the properties of rupatadine offer advantages over cetirizine. Seventy patients with CsU were enrolled. Parameters assessed included: (i) mean number of wheals (MNW); (ii) pruritus; (iii) mean total symptom score (MTSS); (iv) size of wheal; (v) interference of wheals with sleep; and (vi) sedation. Patients with CsU were divided randomly into two groups. Routine investigations were performed at baseline and at the end of the study. Evaluations of MTSS, MNW, and pruritus revealed statistically significant differences at week 3 compared with baseline in the cetirizine group. However, greater reductions in these parameters were obtained with rupatadine. In patients receiving rupatadine, reductions in the MNW, size of wheals, and intensity of erythema were also significant at six weeks (P rupatadine is a particularly attractive therapeutic modality compared with cetirizine for the treatment of CsU. © 2013 The International Society of Dermatology.

    Full Text Available Background D-Lactic acidosis in infants fed lactic acid bacteria-containing products is a concern. Methods The primary objective of this non-inferiority trial was to compare urinary D-lactic acid concentrations during the first 28 days of life in infants fed formula containing Lactobacillus reuteri (1.2 x 10 6 colony forming units (CFU/ml with those fed a control formula. The non-inferiority margin was set at a two-fold increase in D-lactic acid (0.7 mmol/mol creatinine, log-transformed. Healthy term infants in Greece were enrolled between birth and 72 hours of age, and block randomized to a probiotic ( N = 44 or control ( N = 44 group. They were exclusively fed their formulae until 28 days of age and followed up at 7, 14, 28, 112, and 168 ± 3 days. Anthropometric measurements were taken at each visit and tolerance recorded until 112 days. Urine was collected before study formula intake and at all visits up to 112 days and blood at 14 days. Results D-Lactic acid concentration in the probiotic group was below the non-inferiority margin at 28 days: treatment effect -0.03 (95% confidence interval [CI]: [-0.48 to 0.41] mmol/mol creatinine but was above the non-inferiority margin at 7 and 14 days–-treatment effect 0.50 (95% CI: [0.05-0.96] mmol/mol creatinine and 0.45 (95% CI: [0.00-0.90] mmol/mol creatinine, respectively. Blood acid excess and pH, anthropometry, tolerance, and adverse events (AEs were not significantly different between groups. Conclusion Intake of L. reuteri -containing formula was safe and did not cause an increase in D-lactic acid beyond two weeks. Trial Registration ClinicalTrials.gov NCT01119170.

    Full Text Available Gastroesophageal reflux (GER is a common, chronic, relapsing symptom. Often people self-diagnose and self-treat it even though health-related quality of life is significantly impaired. In the lack of a valid alternative approach, current treatments focus on suppression of gastric acid secretion by the use of proton pump inhibitors (PPIs, but people with GER have a significantly lower response rate to therapy. We designed a randomized double-blinded controlled clinical study to evaluate the efficacy and the safety of a formulation based on sodium alginate/bicarbonate in combination with extracts obtained from Opuntia ficus-indica and Olea europaea associated with polyphenols (Mucosave®; verum, on GER-related symptoms. Male/female 118 (intention to treat subjects with moderate GER and having at least 2 to 6 days of GER episodes/week were treated with verum (6 g/day or placebo for two months. The questionnaires Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQoL and Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS were self-administered by participants before the treatment and at the end of the treatment. Verum produced statistically significant reduction of GERD-HRQoL and GSAS scores, −56.5% and −59.1%, respectively, in comparison to placebo. Heartburn and acid regurgitation episodes for week were significantly reduced by verum (p<0.01. Results indicate that Mucosave formulation provides an effective and well-tolerated treatment for reducing the frequency and intensity of symptoms associated with gastroesophageal reflux.

    The study objectives were to evaluate the efficacy, safety, tolerability, and pharmacokinetics of RP5063 versus placebo. The study was conducted in adults with acute exacerbation of schizophrenia or schizoaffective disorder. This 28-day, multicenter, placebo-controlled, double-blind study randomized 234 subjects to RP5063 15, 30, or 50mg; aripiprazole; or placebo (3:3:3:1:2) once daily. The aripiprazole arm was included solely to show assay sensitivity and was not powered to show efficacy. The primary endpoint was change from baseline to Day 28/EOT (End-of-Treatment) in Positive and Negative Syndrome Scale (PANSS) total score; secondary endpoints included PANSS subscales, improvement ≥1 point on the Clinical Global Impressions-Severity (CGI-S), depression and cognition scales. The primary analysis of PANSS Total showed improvement by a mean (SE) of -20.23 (2.65), -15.42 (2.04), and -19.21 (2.39) in the RP5063 15, 30, and 50mg arms, versus -11.41 (3.45) in the placebo arm. The difference between treatment and placebo reached statistical significance for the 15mg (p=0.021) and 50mg (p=0.016) arms. Improvement with RP5063 was also seen for multiple secondary efficacy outcomes. Discontinuation for any reason was much lower for RP5063 (14%, 25%, 12%) versus placebo (26%) and aripiprazole (35%). The most common treatment-emergent adverse events (TEAE) in the RP5063 groups were insomnia and agitation. There were no significant changes in body weight, electrocardiogram, or incidence of orthostatic hypotension; there was a decrease in blood glucose, lipid profiles, and prolactin levels. In conclusion, the novel dopamine serotonin stabilizer, RP5063 is an efficacious and well-tolerated treatment for acute exacerbation of schizophrenia or schizoaffective disorder. Copyright © 2017.

    The objective of this study was to determine steady-state gabapentin exposures and corresponding relief of symptoms and safety profile produced by 4 dose levels of gabapentin enacarbil (GEn) in subjects with restless legs syndrome (RLS). Subjects with RLS (n = 217) were randomized to receive once-daily, orally administered GEn 600 (n = 48), 1200 (n = 45), 1800 (n = 38), or 2400 mg (n = 45) or placebo (n = 41) in this 12-week, double-blind, multicenter study (NCT01332305). Clinic visits were at screening, baseline, and weeks 1, 2, 3, 4, 6, 8, 10, and 12; plasma gabapentin concentrations were measured by a validated liquid chromatography-mass spectrometry/mass spectrometry method at weeks 4 and 12. Exposure to gabapentin was proportional to GEn dose. Time to maximum plasma concentration was 7 to 9 hours, and elimination half-life was ~6 hours. The mean reduction from baseline to week 12 in International Restless Legs Syndrome Rating Scale total score and proportions of subjects with "much improved"/"very much improved" Clinical Global Impression-Improvement scores (investigator and patient ratings) ranged from -12.9 to -13.9 for GEn treatment groups versus -9.3 for placebo. The 2 most commonly reported adverse events were somnolence and dizziness. Gabapentin exposure was approximately proportional to GEn dose. Efficacy data showed that a once-daily dose of GEn 600 to 2400 mg provides greater relief of RLS symptoms than placebo; GEn was generally well tolerated with an adverse event profile consistent with gabapentin.

    Previous studies suggest a lower dose of desmopressin orally disintegrating tablet may be effective in females compared to males with nocturia. We confirm the efficacy and safety of 25 μg desmopressin orally disintegrating tablet compared to placebo in female patients. In this 3-month, randomized, double-blind, parallel group study 25 μg desmopressin once daily was compared to placebo in women with nocturia (2 or more nocturnal voids). The co-primary efficacy end points were change from baseline in mean number of nocturnal voids and proportion of patients achieving at least a 33% reduction from baseline in the mean number of nocturnal voids (33% responders). The full analysis set comprised 261 patients (age range 19 to 87 years). Desmopressin significantly reduced the mean number of nocturnal voids and increased the odds of a 33% or greater response compared to placebo during 3 months, assessed by longitudinal analysis (-0.22, p = 0.028 and OR 1.85, p = 0.006, respectively). Desmopressin increased the mean time to first nocturnal void by 49 minutes compared to placebo at 3 months (p = 0.003). The response to desmopressin was seen by week 1 of treatment and was sustained throughout the trial. Significant increases in health related quality of life and sleep quality were observed compared to placebo. Desmopressin was well tolerated. Serum sodium levels remained greater than 125 mmol/L throughout the trial and 3 transient decreases to less than 130 mmol/L were recorded. At a dose of 25 μg, desmopressin orally disintegrating tablet is an effective and well tolerated treatment for women with nocturia. Treatment provides rapid and sustained improvement in nocturia and quality of life. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    To study the effect of tolvaptan on non-acute, non-hypovolemic hyponatremia in inappropriate secretion of antidiuretic hormone (SIADH) syndrome in Chinese patients. Hyponatremic SIADH patients received placebo (N = 18) or tolvaptan (N = 19) at an initial dose of 15 mg/day with further titration to 30 mg/day and 60 mg/day based on serum sodium concentrations. Randomized, double-blind, placebo-controlled trial. Primary endpoint was the change of the serum sodium from baseline to days 4 and 7. Analysis of covariance (ANCOVA) was used for statistical analysis. At day 4, average daily changes in serum sodium levels from baseline was 1.9 ± 2.9 mmol/L (1.9 ± 2.9 mEq/L) in the placebo group and 8.1 ± 3.6 mmol/L (8.1 ± 3.6 mEq/L) in the tolvaptan group; at day 7, the values were 2.5 ± 3.9 mmol/L (2.5 ± 3.9 mEq/L) and 8.6 ± 3.9 mmol/L (8.6 ± 3.9 mmEq/L) for the placebo and tolvaptan groups (ANCOVA, P tolvaptan group. The most common adverse events occurring in the tolvaptan group were dry mouth and thirst. Tolvaptan demonstrated superiority to placebo in the treatment of Chinese SIADH patients with hyponatremia by elevating serum sodium concentration with acceptable safety profile. © 2014, The American College of Clinical Pharmacology.

    Objectives The aim of this randomized, double-blind, placebo-controlled trial was to determine the efficacy and safety of Ginkgo biloba extract in patients diagnosed with vascular cognitive impairment (VCI). Methods A total of 90 patients (aged 67.1±8.0 years; 59 women) were randomly allocated (1:1:1) to receive G. biloba 120 mg, G. biloba 60 mg, or placebo during a 6-month period. Assessment was made for efficacy indicators, including neuropsychological tests scores (Sandoz Clinical Assessment Geriatric Scale, Folstein Mini-Mental State Examination, Mattis Dementia Rating Scale, and Clinical Global Impression) and transcranial Doppler ultrasound findings. Safety indicators included laboratory findings, reported adverse reactions, and clinical examination. Results At the end of 6-month study period, G. biloba 120 and 60 mg showed a statistically significant positive effect in comparison with placebo only on the Clinical Global Impression score (2.6±0.8 vs 3.1±0.7 vs 2.8±0.7, respectively; P=0.038). The Clinical Global Impression score showed a significant deterioration from the baseline values in the placebo group (−0.3±0.5; P=0.021) as opposed to G. biloba groups. No significant differences were found in the transcranial Doppler ultrasound findings. Adverse reactions were significantly more common and serious in the placebo group (16 subjects) than in either of the two G. biloba extract groups (eight and nine subjects, respectively), whereas laboratory findings and clinical examinations revealed no differences between the groups receiving G. biloba extract and placebo. Conclusion According to our results, G. biloba seemed to slow down the cognitive deterioration in patients with VCI, but the effect was shown in only one of the four neuropsychological tests administered. However, because of this mild effect in combination with a few adverse reactions, we cannot say that it is ineffective or unsafe either. Further studies are still needed to provide

    To evaluate the efficacy and safety of lanreotide depot/autogel 120 mg for the control of carcinoid syndrome (CS) symptoms in patients with neuroendocrine tumors (NETs). This was a 16-week, randomized, double-blind, phase 3 trial (Clinicaltrials.gov: NCT00774930). Patients with/without prior somatostatin analog (SSA) use were randomized to lanreotide depot/autogel 120 mg or placebo every 4 weeks, with access to short-acting octreotide as rescue medication. The primary endpoint was the percentage of days in which short-acting octreotide was used, which was assessed from daily diaries using an analysis of covariance including the stratification variables baseline short-acting octreotide use and frequency of diarrhea/flushing. The proportions of patients experiencing treatment success was a supportive analysis. Adverse events were recorded at all visits. A total of 115 patients were enrolled (lanreotide, n = 59; placebo, n = 56). The adjusted mean (95% confidence interval [CI]) percentage of days with rescue octreotide use (primary endpoint) was significantly lower in the lanreotide (33.7%; 95% CI, 25.0%-42.4%) versus the placebo group (48.5%; 95% CI, 39.6%-57.4%), representing an absolute difference of -14.8% (95% CI, -26.8% to -2.8%; P = .017). The odds ratio of full/partial treatment success (≤3 days short-acting octreotide use weeks 12 to 15) was significantly greater with lanreotide than placebo (2.4; 95% CI, 1.1-5.3; P = .036). No new safety concerns were identified, and lanreotide was well tolerated. Lanreotide depot/autogel is effective for the control of CS symptoms in patients (SSA-naïve or experienced) with NETs.

    Full Text Available Abstract Background Anorexia Nervosa (AN is a serious, debilitating condition that causes significant physical, emotional, and functional impairment. The condition is characterized by destructive weight loss behaviours and a refusal to maintain body weight at or above a minimally normal weight for age and height. AN often develops in adolescence and is a predominantly female disorder. Treatment for AN typically involves medical, nutritional and psychological interventions. Pharmacotherapy is also often used; however, the literature on the effectiveness of these drugs in a pediatric population is very limited. Olanzapine, which is an 'atypical' antipsychotic, is becoming more widespread in the treatment of AN. Olanzapine is hypothesized to facilitate weight gain, while decreasing levels of agitation and decreasing resistance to treatment in young women with AN. This randomized, double-blind placebo-controlled trial seeks to examine the effectiveness and safety of olanzapine in female youth with AN. Methods/Design Adolescent females between the ages of 12 and 17 diagnosed with AN (either restricting or binge/purge type or Eating Disorder Not Otherwise Specified with a Body Mass Index of less than or equal to 17.5, will be offered inclusion in the study. Patients will be randomly assigned to receive either olanzapine or placebo. Patients assigned to receive olanzapine will start at a low dose of 1.25 mg/day for three days, followed by 2.5 mg/day for four days, 5 mg/day for one week, then 7.5 mg/day (the target dose chosen for 10 weeks. After 10 weeks at 7.5 mg the medication will be tapered and discontinued over a period of two weeks. The effectiveness of olanzapine versus placebo will be determined by investigating the change from baseline on measures of eating attitudes and behaviors, depression and anxiety, and change in Body Mass Index at week 12, and after a follow-up period at week 40. It is anticipated that 67 participants will be recruited

    The objective of this multicenter, double-blind, placebo-controlled, randomized withdrawal study was to evaluate the efficacy and safety of ALO-02, an abuse-deterrent formulation containing pellets of extended-release oxycodone hydrochloride (HCl) surrounding sequestered naltrexone HCl, compared with placebo in the treatment of moderate-to-severe chronic low back pain. An open-label titration period in which all patients received ALO-02 was followed by a double-blind treatment period where patients meeting treatment response criteria were randomized to either a fixed dose of ALO-02 or placebo. Daily average low back pain was assessed using an 11-point numeric rating scale (NRS)-Pain. Of the 663 patients screened, 410 received ALO-02 during the open-label conversion and titration period and 281 patients were randomized to the double-blind treatment period (n = 134, placebo; n = 147, ALO-02). Change in the mean NRS-Pain score from randomization baseline to the final 2 weeks of the treatment period was significantly different favoring ALO-02 compared with placebo (P = 0.0114). Forty-four percent of patients treated with placebo and 57.5% of patients treated with ALO-02 reported ≥30% improvement in weekly average NRS-Pain scores from screening to the final 2 weeks of the treatment period (P = 0.0248). In the double-blind treatment period, 56.8% of patients in the ALO-02 group and 56.0% of patients in the placebo group experienced a treatment-emergent adverse event (TEAE). The most common treatment-related TEAEs for ALO-02 during the treatment period were nausea, vomiting, and constipation, consistent with opioid therapy. ALO-02 has been demonstrated to provide significant reduction of pain in patients with chronic low back pain and has a safety profile similar to other opioids.

    We assessed the efficacy and safety of once-daily eslicarbazepine acetate in comparison with twice-daily (BID) controlled-release carbamazepine (carbamazepine-CR) monotherapy in newly diagnosed focal epilepsy patients. This randomized, double-blind, noninferiority trial (NCT01162460) utilized a stepwise design with 3 dose levels. Patients who remained seizure-free for the 26-week evaluation period (level A: eslicarbazepine acetate 800 mg/carbamazepine-CR 200 mg BID) entered a 6-month maintenance period. If a seizure occurred during the evaluation period, patients were titrated to the next target level (level B: eslicarbazepine acetate 1200 mg/carbamazepine-CR 400 mg BID, level C: eslicarbazepine acetate 1600 mg/carbamazepine-CR 600 mg BID) and the evaluation period began again. The primary endpoint was the proportion of seizure-free patients for 6 months after stabilization in the per protocol set. The predefined noninferiority criteria were -12% absolute and -20% relative difference between treatment groups. Eight hundred fifteen patients were randomly assigned; 785 (388 in the eslicarbazepine acetate group and 397 in the carbamazepine-CR group) were included in the per protocol set, and 813 (401 in the eslicarbazepine acetate group and 412 in the carbamazepine-CR group) were included in the full analysis set for the primary analysis. Overall, 71.1% of eslicarbazepine acetate-treated patients and 75.6% of carbamazepine-CR-treated patients were seizure-free for ≥6 months at the last evaluated dose (average risk difference = -4.28%, 95% confidence interval [CI] = -10.30 to 1.74; relative risk difference = -5.87%, 95% CI = -13.50 to 2.44) in the per protocol set. Rates of treatment-emergent adverse events were similar between groups for patients in the safety set. Noninferiority was also demonstrated in the full analysis set, as 70.8% of patients with eslicarbazepine acetate and 74.0% with carbamazepine-CR were seizure-free at the last evaluated dose

    Full Text Available Background and Aim: Mild cognitive impairment (MCI is characterized by declined cognitive function greater than that expected for a person’s age. The clinical significance of this condition is its possible progression to dementia. MLC601 is a natural neuroprotective medication that has shown promising effects in Alzheimer disease. Accordingly, we conducted this randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of MLC601 in MCI patients. Methods: Seventy-two patients with a diagnosis of MCI were recruited. The included participants were randomly assigned to groups to receive either MLC601 or placebo. An evaluation of global cognitive function was performed at baseline as well as at 3-month and 6-month follow-up visits. Global cognitive function was assessed by Mini-Mental State Examination (MMSE and Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog scores. Efficacy was evaluated by comparing global function scores between the 2 groups during the study period. Safety assessment included adverse events (AEs and abnormal laboratory results. Results: Seventy patients completed the study, 34 in the MLC601 group and 36 in the placebo group. The mean changes (±SD in cognition scores over 6 months in the MLC601 group were –2.26 (±3.42 for the MMSE and 3.82 (±6.16 for the ADAS-cog; in the placebo group, they were –2.66 (±3.43 for the MMSE and 4.41 (±6.66 for the ADAS-cog. The cognition changes based on both MMSE and ADAS-cog scores were statistically significant between the placebo and the MLC601 group (p < 0.001. Only 5 patients (14.7% reported minor AEs in the MLC601 group, the most commonly reported of which were gastrointestinal, none of them leading to patient withdrawal. Conclusion: MLC601 has shown promising efficacy and acceptable AEs in MCI patients.

    For regulatory approval, consistency in manufacturing of vaccine lots is expected to be demonstrated in confirmatory immunogenicity studies using two-sided equivalence trials. This randomized, double-blind study (NCT01323972) assessed consistency of three RTS,S/AS01 malaria vaccine batches formulated from commercial-scale purified antigen bulk lots in terms of anti-CS-responses induced. Healthy children aged 5-17 months were randomized (1:1:1:1) to receive RTS,S/AS01 at 0-1-2 months from one of three commercial-scale purified antigen bulk lots (1600 litres-fermentation scale; commercial-scale lots), or a comparator vaccine batch made from pilot-scale purified antigen bulk lot (20 litres-fermentation scale; pilot-scale lot). The co-primary objectives were to first demonstrate consistency of antibody responses against circumsporozoite (CS) protein at one month post-dose 3 for the three commercial-scale lots and second demonstrate non-inferiority of anti-CS antibody responses at one month post-dose 3 for the commercial-scale lots compared to the pilot-scale lot. Safety and reactogenicity were evaluated as secondary endpoints. One month post-dose-3, anti-CS antibody geometric mean titres (GMT) for the 3 commercial scale lots were 319.6 EU/ml (95% confidence interval (CI): 268.9-379.8), 241.4 EU/ml (207.6-280.7), and 302.3 EU/ml (259.4-352.3). Consistency for the RTS,S/AS01 commercial-scale lots was demonstrated as the two-sided 95% CI of the anti-CS antibody GMT ratio between each pair of lots was within the range of 0.5-2.0. GMT of the pooled commercial-scale lots (285.8 EU/ml (260.7-313.3)) was non-inferior to the pilot-scale lot (271.7 EU/ml (228.5-323.1)). Each RTS,S/AS01 lot had an acceptable tolerability profile, with infrequent reports of grade 3 solicited symptoms. No safety signals were identified and no serious adverse events were considered related to vaccination. RTS,S/AS01 lots formulated from commercial-scale purified antigen bulk batches induced a

    A phase IV, multicentre, randomized, double-blind, parallel-group, comparative study was conducted in Japanese subjects with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control, despite treatment with alogliptin in addition to diet and/or exercise therapy. Subjects with glycated haemoglobin (HbA1c) concentrations of 6.9-10.5% were randomized to receive 16 weeks' double-blind treatment with pioglitazone 15 mg, 30 mg once daily or placebo added to alogliptin 25 mg once daily. The primary endpoint was the change in HbA1c from baseline at the end of treatment period (week 16). Both pioglitazone 15 and 30 mg combination therapy resulted in a significantly greater reduction in HbA1c than alogliptin monotherapy [-0.80 and -0.90% vs 0.00% (the least squares mean using analysis of covariance model); p < 0.0001, respectively]. The overall incidence rates of treatment-emergent adverse events were similar among the treatment groups. Pioglitazone/alogliptin combination therapy was effective and generally well tolerated in Japanese subjects with T2DM and is considered to be useful in clinical settings. © 2015 John Wiley & Sons Ltd.

Patients and methods: The study was a multicenter, randomized, double-blind, and placebo-controlled trial. Altogether, 376 women were assessed for eligibility, and signed informed consent. One hundred and sixty eligible women with abnormal, also called intermediate, vaginal microflora, as indicated by a Nugent score of 4–6 and pH >4.5 and zero or low Lactobacillus count, were randomized. Each participant was examined four times during the study. Women were randomly allocated to receive either the probiotic preparation inVag®, or a placebo (one capsule for seven consecutive days vaginally. The product inVag includes the probiotic strains Lactobacillus fermentum 57A, Lactobacillus plantarum 57B, and Lactobacillus gasseri 57C. We took vaginal swabs during visits I, III, and IV to determine the presence and abundance of bacteria from the Lactobacillus genus, measure the pH, and estimate the Nugent score. Drug safety evaluation was based on analysis of the types and occurrence of adverse events. Results: Administration of inVag contributed to a significant decrease (between visits in both vaginal pH (P<0.05 and Nugent score (P<0.05, and a significant increase in the abundance of Lactobacillus between visit I and visits III and IV (P<0.05. Molecular typing revealed the presence of Lactobacillus strains originating from inVag in 82% of women taking the drug at

    Introduction Fibromyalgia is a chronic disorder characterized by widespread pain and tenderness. Prior trials have demonstrated the efficacy of pregabalin for the relief of fibromyalgia symptoms, and it is approved for the treatment of fibromyalgia in the United States. However, prior to this study, there has not been a large-scale efficacy trial in patients with fibromyalgia in Japan. Methods This randomized, double-blind, multicenter, placebo-controlled trial was conducted at 44 centers in Japan to assess the efficacy and safety of pregabalin for the symptomatic relief of pain in fibromyalgia patients. Patients aged ≥18 years who had met the criteria for fibromyalgia were randomized to receive either pregabalin, starting at 150 mg/day and increasing to a maintenance dose of 300 or 450 mg/day, or placebo, for 15 weeks. The primary efficacy endpoint was mean pain score at final assessment. Secondary endpoints included Patient Global Impression of Change (PGIC) together with measures of sleep, physical functioning and quality of life. Results A total of 498 patients (89% female) were randomized to receive either pregabalin (n = 250) or placebo (n = 248). Pregabalin significantly reduced mean pain score at final assessment (difference in mean change from baseline, compared with placebo -0.44; P = 0.0046) and at every week during the study (P pregabalin treatment compared with placebo, including PGIC (percentage reporting symptoms "very much improved" or "much improved", 38.6% vs 26.7% with placebo; P = 0.0078); pain visual analog scale (difference in mean change from baseline, compared with placebo -6.19; P = 0.0013); Fibromyalgia Impact Questionnaire total score (-3.33; P = 0.0144); and quality of sleep score (-0.73; P pregabalin, at doses of up to 450 mg/day, was effective for the symptomatic relief of pain in Japanese patients with fibromyalgia. Pregabalin also improved measures of sleep and functioning and was well tolerated. These data indicate that pregabalin

    Combinations of drugs with distinct and complementary mechanisms of action may offer improved efficacy in the treatment of chronic obstructive pulmonary disease (COPD). In two 12-week, double-blind, parallel-group studies, patients with COPD were randomized 1:1:1 to once-daily umeclidinium (UMEC; 62.5 μg and 125 μg) or placebo (PBO), added to twice-daily fluticasone propionate/salmeterol (FP/SAL; 250/50 μg). In both studies, the primary efficacy measure was trough forced expiratory volume in 1 second (FEV1) at Day 85. Secondary endpoints were weighted-mean (WM) FEV1 over 0-6 hours post-dose (Day 84) and rescue albuterol use. Health-related quality of life outcomes (St. George's Respiratory Questionnaire [SGRQ] and COPD assessment test [CAT]) were also examined. Safety was assessed throughout. Both UMEC+FP/SAL doses provided statistically significant improvements in trough FEV1 (Day 85: 0.127-0.148 L) versus PBO+FP/SAL. Similarly, both UMEC+FP/SAL doses provided statistically-significant improvements in 0-6 hours post-dose WM FEV1 versus PBO+FP/SAL (Day 84: 0.144-0.165 L). Rescue use over Weeks 1-12 decreased with UMEC+FP/SAL in both studies versus PBO+FP/SAL (Study 1, 0.3 puffs/day [both doses]; Study 2, 0.5 puffs/day [UMEC 125+FP/SAL]). Decreases from baseline in CAT score were generally larger for both doses of UMEC+FP/SAL versus PBO+FP/SAL (except for Day 84 Study 2). In Study 1, no differences in SGRQ score were observed between UMEC+FP/SAL and PBO+FP/SAL; however, in Study 2, statistically significant improvements were observed with UMEC 62.5+FP/SAL (Day 28) and UMEC 125+FP/SAL (Days 28 and 84) versus PBO+FP/SAL. The incidence of on-treatment adverse events across all treatment groups was 37-41% in Study 1 and 36-38% in Study 2. Overall, these data indicate that the combination of UMEC+FP/SAL can provide additional benefits over FP/SAL alone in patients with COPD.

    Allergic rhinitis is a complex inflammatory disease whose pathophysiology involves local and systemic mechanisms. Rupatadine, a molecule with intense antihistaminic activity and with antagonist PAF effects through its interaction with specific receptors, is indicated for the treatment of intermittent or persistent allergic rhinitis and urticaria. This systematic review was aimed at identifying in the most important databases, up to January 2013, the double-blind placebo-controlled randomized trials administering rupatadine in allergic rhinitis. No restriction was introduced for treatment duration and dose, study design, population age, allergen exposition and disease classification. The methodological quality of included studies and risk of bias were systematically assessed. Meta-analysis was performed when possible to summarize information. Seventeen of 413 initially identified records were fully assessed for eligibility. Ten trials involving 2573 patients overall met the inclusion criteria and entered the analysis. Their internal validity was satisfactory. Data synthesis showed that rupatadine is superior to placebo in relieving the overall allergy symptoms on reflective (SMD: -0.37, 95% CI -0.46 to -0.27; p rupatadine. No difference was observed in the incidence of total adverse reactions between rupatadine and placebo (OR 1.23, 95% CI 0.95 to 1.59; p = 0.12). Randomized double-blind controlled trials show a favorable risk-benefit ratio in rupatadine for the treatment of allergic rhino-conjunctivitis. This evidence is strengthened when data are pooled in the form of meta-analysis, where accurate and robust effect estimations are derived from a large population.

    The goal of this study was to determine if a lidocaine hydrochloride monohydrate powder intradermal system designed to provide cutaneous analgesia is efficacious, safe, and tolerable for pediatric subjects compared with a sham placebo system. COMFORT-004, A Phase III, Randomized, Double-Blind, Placebo-Controlled Study to Confirm the Effectiveness and Safety of ALGRX 3268 in Pediatric Subjects, was a single-dose, parallel group study of children undergoing venipuncture or peripheral venous cannulation at the antecubital fossa or back of the hand. Included were subjects (3-18 years) in 3 age groups: 3-7, 8-12, and 13-18 years. Excluded were those with recent similar procedures or with implantable devices or skin pathologies at the anatomical site, insufficient cognitive skills, or allergies to local anesthetics or adhesives. Subjects were randomized to receive the needle-free powder lidocaine delivery system (active system, 0.5 mg of lidocaine/21 ± 1 bar of pressure [n = 269]) or sham placebo (n = 266) 1-3 minutes before venipuncture or peripheral venous cannulation. Analgesic efficacy was assessed patient self-report of venous access pain (Wong-Baker FACES Pain Rating Scale [3-18 years] and visual analog scale [VAS; 8-18 years]) and parental observational VAS. Safety assessments included adverse events (AEs) and relationship to study treatment. Skin signs and symptoms were graded numerically. Wong-Baker FACES scores, VAS, and parental VAS were analyzed by using an ANOVA model. Responder ratings and success rates were compared by using a Cochran-Mantel-Haenszel test stratified according to center, age group, and body site. The active system group had significantly (P = 0.0022) less pain compared with the sham placebo in all age groups combined according to the modified Wong-Baker FACES scale. Secondary efficacy analyses found that the active system resulted in less pain as assessed by subjects' VAS pain assessments aged 8-18 years (P = 0.1856), responder analysis (P

    Tanacetum parthenium (feverfew), is a well-known herb for the prophylactic treatment of migraine. The primary objective was to show a dose-response of a new stable extract (MIG-99) reproducibly manufactured with supercritical CO2 from feverfew (T. parthenium). Furthermore, the study should provide data on the safety and tolerability of MIG-99. In a randomized, double-blind, multicentre, controlled trial with an adaptive design, the clinical efficacy and safety of three dosages of MIG-99 (2.08 mg; 6.25 mg; 18.75 mg t.i.d.) were compared with placebo. The patients (n = 147) suffered from migraine with and without aura according to International Headache Society (IHS) criteria and were treated with one of the study medications for 12 weeks after a 4-week baseline period. The primary efficacy parameter was the number of migraine attacks during the last 28 days of the treatment period compared with baseline. Secondary endpoints were total and average duration and intensity of migraine attacks, mean duration of the single attack, number of days with accompanying migraine symptoms, number of days with inability to work due to migraine as well as type and amount of additionally taken medications for the treatment of migraine attacks. The design of the study included a pre-planned adaptive interim analysis for patients with at least four migraine attacks within the baseline period. With respect to the primary and secondary efficacy parameter, a statistically significant difference was not found between the overall and the confirmatory intention-to-treat (ITT) sample in the exploratorily analysed four treatment groups. The frequency of migraine attacks for the predefined confirmatory subgroup of patients (n = 49) with at least four migraine attacks during the baseline period decreased in a dose-dependent manner (P = 0.001). The highest absolute change of migraine attacks was observed under treatment with 6.25 mg t.i.d. (mean +/- SD = -1.8 +/- 1.5 per 28 days) compared with

Recently, it has been hypothesized that glial activation may be a contributor to migraine; therefore, this study investigated whether the potential glial inhibitor, ibudilast, could attenuate CM. Methods: The study was of double-blind, randomized, placebo-controlled, two-period crossover design. Participants were randomized to receive either ibudilast (40 mg twice daily or placebo treatment for 8 weeks. Subsequently, the participants underwent a 4-week washout period followed by a second 8-week treatment block with the alternative treatment. CM participants completed a headache diary 4 weeks before randomization throughout both treatment periods and 4 weeks after treatment. Questionnaires assessing quality of life and cutaneous allodynia were collected on eight occasions throughout the study. Results: A total of 33 participants were randomized, and 14 participants completed the study. Ibudilast was generally well tolerated with mild, transient adverse events, principally nausea. Eight weeks of ibudilast treatment did not reduce the frequency of moderate to severe headache or of secondary outcome measures such as headache index, intake of symptomatic medications, quality of life or change in cutaneous allodynia. Conclusion: Using the current regimen, ibudilast does not improve migraine with CM participants. Keywords: chronic migraine, glia, ibudilast, headache, immune system

    Full Text Available Background: Dental anxiety is a relatively frequent problem that can lead to more serious problems such as a child entering a vicious cycle as he/she becomes reluctant to accept the required dental treatments. The aim of this randomized double-blind clinical trial study was to evaluate the anxiolytic and sedative effect of pregabalin in children. Materials and Methods: Twenty-five children were randomized to a double-blind placebo-controlled crossover clinical trial. Two visits were scheduled for each patient. At the first visit, 75 mg pregabalin or placebo was given randomly, and the alternative was administered at the next visit. Anxiolytic and sedative effects were measured using the visual analogue scale. The child′s behavior was rated with the Frankl behavioral rating scale and the sedation level during the dental procedure was scored using the Ramsay sedation scale. The unpaired, two-tailed Student′s t-test was used to compare the mean changes of visual analog scale (VAS for anxiety in the pregabalin group with that of the placebo group. A repeated measures MANOVA model was used to detect differences in sedation level in the pregabalin and placebo groups regarding the interaction of 3-time measurements; sub-group analysis was performed using Student′s t-test. The Mann-Whitney U-test was used to analyze the nonparametric data of the Frankl and Ramsay scales. A P < 0.05 was considered significant. Results: The reduction of the VAS-anxiety score from 2 h post-dose was statistically significant in the pregabalin group. From 2 h to 4 h post-dose, the VAS-sedation score increased significantly in the pregabalin group. The child′s behavior rating was not significantly different between the groups. The number of "successful" treatment visits was higher in the pregabalin group compared to the placebo group. Conclusion: Significant anxiolytic and sedative effects can be anticipated 2 h after oral administration of pregabalin without serious

    The aim of this comparative double-blind, prospective, randomized, clinical trial was to evaluate two amoxicillin administration patterns. The first was a short prophylactic therapy and the second a long postoperative regimen. The study population consisted of 160 patients who underwent mandibular third molar extraction. Patients were randomized into two equal groups. In group 1, 2 grams of amoxicillin were administered 1 hour before the procedure and 1 gram 6 hours after surgery. In group 2, patients received 1 gram of amoxicillin 6 hours after surgery followed by 1 gram every 8 hour for 4 days. All patients received the same number of tablets thanks to the use of placebo pills. A total of 25 variables were evaluated, such as alveolitis, surgical infection, number of analgesic needed, subjective pain scale, post-surgical inflammation, consistency of the diet, axillary temperature and millimeters of mouth opening loss after the surgery. No statistically significant post-operative differences were found within the recorded parameters between the groups. Postoperative 4-days amoxicillin therapy is not justified.

    Topiroxostat, a selective xanthine oxidoreductase inhibitor, is used in Japan for the treatment of hyperuricemic patients with or without gout. In terms of the effectiveness of topiroxostat in lowering serum urate levels, the dose-response relationship has been evaluated; however, it remains to be verified. A randomized, multi-center, double-blinded study of topiroxostat was performed for Japanese hyperuricemic patients with or without gout. During the 16-week study, 157 Japanese hyperuricemic patients with or without gout were randomly assigned to receive a placebo, topiroxostat at 120 or 160 mg/day, or allopurinol at 200 mg/day. The primary endpoint of this study was to determine the lowering rate of serum uric acid levels compared to those of baseline at the end of administration. A dose-response relationship (regarding decreases in the serum urate levels) was confirmed for the placebo and topiroxostat at 120 and at 160 mg/day. Moreover, at the end of administration, the lowering rate of serum urate levels was determined to be -44.8% in the topiroxostat 160-mg/day group. No significant difference in the incidence of adverse events was observed among all groups, including the allopurinol group. The serum urate-lowering effect of topiroxostat was found to have a dose-response relationship in Japanese hyperuricemic patients with or without gout.

    Purpose This study was performed to evaluate topical 1% diclofenac/3% menthol gel in treating ankle sprain. Design In this randomized, double-blind, placebo-controlled trial, adolescents and adults with acute ankle sprain (N = 385) applied 4 g of gel containing 1% diclofenac/3% menthol (n = 117), 1% diclofenac (n = 112), 3% menthol (n = 77), or placebo (n = 75) four times daily. The primary outcome was the area under the curve of pain intensity (PI) on movement [0 (no pain) to 10 (extreme pain)] from 24 to 72 hours post-application (AUC 1-3 days ). Secondary outcomes included pain relief (PR); PI; time to onset of PR, meaningful PR, cooling, and complete recovery; PI difference; sum of PI difference; total PR; reduction in ankle swelling; and the patient's global assessment of response to treatment. Results There were no statistically significant differences in AUC 1-3 between 1% diclofenac/3% menthol and placebo, diclofenac, or menthol gels and no meaningful advantages of 1% diclofenac/3% menthol for any secondary outcome. There was a higher incidence of skin and application-site events with 1% diclofenac/3% menthol than with placebo or 1% diclofenac. Conclusion No significant improvement was observed with topical 1% diclofenac/3% menthol gel compared with placebo, 1% diclofenac, or 3% menthol gel in treating pain from ankle sprain.

    Potential effects of the selective β(3)-adrenoceptor agonist mirabegron on cardiac repolarization were studied in healthy subjects. The four-arm, parallel, two-way crossover study was double-blind and placebo- and active (moxifloxacin)-controlled. After 2 baseline ECG days, subjects were randomized to one of eight treatment sequences (22 females and 22 males per sequence) of placebo crossed over with once-daily (10 days) 50, 100, or 200 mg mirabegron or a single 400-mg moxifloxacin dose on day 10. In each period, continuous ECGs were recorded at two baselines and on the last drug administration day. The lower one-sided 95% confidence interval for moxifloxacin effect on QTcI was >5 ms, demonstrating assay sensitivity. According to ICH E14 criteria, mirabegron did not cause QTcI prolongation at the 50-mg therapeutic and 100-mg supratherapeutic doses in either sex. Mirabegron prolonged QTcI interval at the 200-mg supratherapeutic dose (upper one-sided 95% CI >10 ms) in females, but not in males.

    Bilastine, a novel non-sedating second-generation H 1 antihistamine, has been approved in most European countries since 2010. This study aimed to evaluate the superiority of bilastine over placebo in Japanese patients with perennial allergic rhinitis (PAR). This randomized, double-blind, placebo-controlled, parallel-group, phase III study (trial registration number JapicCTI-142600) evaluated the effect of a 2-week treatment period with bilastine (20 mg once daily), fexofenadine (60 mg twice daily), or a matched placebo (double dummy) in patients with PAR. All patients were instructed to record individual nasal and ocular symptoms in diaries daily. The primary endpoint was the mean change in total nasal symptom scores (TNSS) from baseline to Week 2 (Days 10-13). A total of 765 patients were randomly allocated to receive bilastine, fexofenadine, or placebo (256, 254, and 255 patients, respectively). The mean change in TNSS from baseline at Week 2 was significantly decreased by bilastine (-0.98) compared to placebo (-0.63, P = 0.023). Bilastine and fexofenadine showed no significant difference in the primary endpoint. However, the mean change in TNSS from baseline on Day 1 was more significantly decreased by bilastine (-0.99) than by placebo (-0.28, P bilastine 20 mg once daily was effective and tolerable in Japanese patients with PAR, and exhibited a rapid onset of action.

    A total of 101 patients (67 delapril, 34 placebo) with congestive heart failure, New York Heart Association (NYHA) classes II and III, entered a multicenter, randomized (2:1), double-blind, placebo-controlled study to determine the minimum effective and maximum tolerated doses of delapril. Patients received placebo or increasing doses of delapril. After a 2-week run-in period on placebo, patients were randomly assigned to delapril or placebo. The dose of delapril was 7.5 mg twice daily for 2 weeks, 15 mg twice daily for another 2 weeks, followed by 30 mg twice daily for 4 weeks. The dose was increased only if the patient did not present any symptoms of orthostatic hypotension. If such symptoms developed, the code was broken and an open treatment was continued on the minimum effective dose (delapril group). Patients with symptoms of orthostatic hypotension in the placebo group were withdrawn. At the end of the 8-week treatment, 36 (54.5%) patients in the delapril group completed the study on 30 mg twice daily, 12 (18.2%) on 15 mg twice daily, and 18 (27.3%) on 7.5 mg twice daily. Seven patients on placebo were withdrawn because of insufficient therapeutic response; one patient on delapril was lost to follow-up. There was a significant improvement (p < 0.01) in bicycle ergometric performance involving an increase in the exercise duration and the maximum workload tolerated in those patients completing the study on delapril 30 mg twice daily and those finishing on 15 mg twice daily.(ABSTRACT TRUNCATED AT 250 WORDS)

    An imbalance between Th1 and Th2 cells is involved in allergic rhinitis (AR) that may be improved by probiotics. To test the efficacy of the probiotic Lactobacillus paracasei subsp. paracasei LP-33, a double-blind, placebo-controlled, randomized trial was carried out in patients with AR to grass pollen treated with loratadine and presenting altered quality of life. Subjects with persistent AR, symptomatic during the grass pollen season, and a positive skin test or specific immunoglobulin E to grass pollens were included by general practitioners (GPs). All received loratadine for 5 weeks. The primary end point was the improvement in Rhinitis Quality of Life (RQLQ) global score at the fifth week of LP-33 consumption compared with placebo (in addition to loratadine). Secondary end points included nasal and ocular symptoms (individual and total symptom scores), visual analogue scale and time of first exacerbation of the symptoms when loratadine was stopped. A total of 425 subjects were included. Using intent-to-treat analysis, the RQLQ global score decreased significantly more in the LP-33 group than in the placebo group (P=0.0255, difference=-0.286 (95% confidence interval (CI): -0.536; -0.035)). No significant differences were noted for the change of the rhinitis total symptom score 5 global score between groups (P=0.1288, difference=-0.452 (95% CI: -1.036; 0.132)). Significant differences in ocular symptoms (RQLQ) were observed between groups (P=0.0029, difference=-0.4087 (95% CI: -0.6768; -0.1407)). This study performed by GPs shows that LP-33 improves the quality of life of subjects with persistent AR who are currently being treated with an oral H1-antihistamine. Whereas nasal symptoms had not changed, ocular symptoms had consistently improved.

    This randomized, double-blind, placebo-controlled trial (N93-004) evaluated the effects of epoetin alfa on tumor response to chemotherapy and survival in patients with small-cell lung cancer (SCLC). Adult patients with hemoglobin < or = 14.5 g/dL starting chemotherapy received epoetin alfa 150 U/kg or placebo subcutaneously 3 times weekly until 3 weeks after completion of chemotherapy. Survival was assessed for 3 years. The primary end point was the proportion of patients with complete or partial response after three chemotherapy cycles. The trial was terminated prematurely after 224 of a projected 400 patients were accrued. Baseline characteristics were similar between groups. Epoetin alfa and placebo patients (n = 109 and n = 115, respectively) had mean baseline hemoglobin of 12.8 g/dL and 13.0 g/dL, respectively. Overall tumor response was similar between the epoetin alfa and placebo groups after three chemotherapy cycles (72% and 67%, respectively; 95% CI of difference, -6% to 18%) and after completion of chemotherapy (60% and 56%, respectively; 95% CI of difference, -9% to 17%). Epoetin alfa and placebo groups had similar median overall survival (10.5 and 10.4 months, respectively) and overall mortality (91.7% and 87.8%, respectively; hazard ratio, 1.172; 95% CI, 0.887 to 1.549; P = .264). Hemoglobin was maintained in the prechemotherapy range in epoetin alfa patients, but decreased substantially in placebo patients. Fewer epoetin alfa patients than placebo patients required transfusion. These results suggest that in newly diagnosed patients with SCLC epoetin alfa does not affect tumor response to chemotherapy or survival. However, the early trial closure makes these conclusions preliminary.

    Context Cognitive impairment in late-life depression is a core feature of the illness. Objective to test whether donepezil + antidepressant is superior to placebo + antidepressant in (1) improving cognitive performance and instrumental activities of daily living and (2) reducing recurrences of depression over two years of maintenance treatment. Design Randomized, double-blind, placebo controlled maintenance trial. Setting university clinic Main Outcome Measures global neuropsychological performance, cognitive instrumental ADL, and recurrent depression. Results Donepezil + antidepressant temporarily improved global cognition (treatment by time interaction F = 3.78, df = 2, 126, p = .03), but effect sizes were small (Cohen’s d = 0.27: group difference at 1 year). A marginal benefit to cognitive instrumental ADL was also observed (treatment by time interaction; F = 2.94; df = 2, 137, p = 0.06). The donepezil group was more likely to experience recurrent major depression: 35% [95% CI: 24%, 46%] versus 19% [95% CI: 9%, 29%] (log rank chi squared = 3.97, p = .05); hazard ratio = 2.09 [95% CI: 1.00, 4.41]. Post-hoc subgroup analyses showed that, of 57 participants with mild cognitive impairment, 3/30 on donepezil (10%; 95% CI: 0, 21%) and 9/27 on placebo (33%; 95% CI: 16%, 51%) converted to dementia over two years (Fisher exact p = 0.05). The MCI subgroup had a 44 percent recurrence rate of major depression on donepezil verses 12% on placebo (LR=4.91, p=.03). The subgroup with normal cognition (n = 73) showed no benefit on donepezil or increase in recurrence of major depression. Conclusion Whether ChEI should be used as augmentation in the maintenance treatment of late-life depression depends upon a careful weighing of risks and benefits in those with MCI. In cognitively intact patients, donepezil appears to have no clear benefit for preventing progression to MCI/dementia or recurrence of depression. PMID:21199965

    To explore whether the immunization with high-dose (60μg) hepatitis B vaccines in patients receiving methadone maintenance treatment (MMT) could yield a superior protection against hepatitis B infection than did the standard dose (20μg). We conducted a randomized, double-blinded, parallel-controlled trial in MMT patients. Patients with serologically negative hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) were randomized in a ratio of 1:1 to receive three intramuscular injections of 20μg or 60μg recombinant hepatitis B vaccine at months 0, 1, and 6. Serum HBsAg and anti-HBs were measured at months 7 and 12 post-vaccination to assess the immunogenicity. A total of 196 MMT patients were randomized and 195 received at least one injection (98 and 97 in 20 and 60μg vaccine groups, respectively). The 60μg vaccine group showed a seroconversion of anti-HBs of 87.3%, high-level response rate of 56.3%, and GMC of 742.9mIU/mL at month 7. While these results were numerically higher than the 20μg group, a statistical difference was not found. HIV infection and concomitant drug abuse were negatively associated with the robust immune responses. 7.7% of MMT patients receiving at least one dose of vaccine reported solicited adverse reactions within 7days after vaccination, 2.6% reported unsolicited adverse reactions within 28days after vaccination. None of the MMT patients reported serious adverse events or became HBsAg positive during the follow-up. The three-dose regimen of 60μg recombinant hepatitis B vaccine at months 0, 1, and 6 can yield a similar immunogenicity among MMT patients as compared to the 20μg vaccine.

    Vortioxetine (Lu AA21004) is an antidepressant with a mechanism of action thought to be related to a combination of 2 pharmacologic actions: direct modulation of several receptors and inhibition of the serotonin transporter. To evaluate the efficacy of vortioxetine 10 and 20 mg once daily in outpatients with major depressive disorder. This 8-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group study was conducted from July 2010 to January 2012 among adults with a primary diagnosis of recurrent major depressive disorder (DSM-IV-TR). Eligible subjects were randomized in 1:1:1 ratio to 1 of 3 treatment arms: vortioxetine 10 mg, vortioxetine 20 mg, or placebo once daily for 8 weeks. Subjects who completed the 8-week trial entered a 2-week blinded discontinuation period to assess potential discontinuation symptoms. The primary endpoint was the least squares mean change in Montgomery-Asberg Depression Rating Scale (MADRS) total score from baseline. Key secondary outcomes were analyzed in the following prespecified sequential order: MADRS response (≥ 50% decrease from baseline in total score), Clinical Global Impressions-Improvement score, change from baseline in MADRS total score in subjects with baseline Hamilton Anxiety Rating Scale score ≥ 20, MADRS remission (total score ≤ 10), and change from baseline in Sheehan Disability Scale total score (all at week 8). A total of 462 subjects were randomized to placebo (n = 157), vortioxetine 10 mg (n = 155), and vortioxetine 20 mg (n = 150). Mean (SE) reductions from baseline in MADRS total score (week 8) were -10.77 (± 0.807), -12.96 (± 0.832), and -14.41 (± 0.845) for the placebo, vortioxetine 10 mg (P = .058 vs placebo), and vortioxetine 20 mg (P = .002 vs placebo) groups. MADRS response/remission was achieved in 28.4%/14.2%, 33.8%/21.4%, and 39.2%/22.3% of subjects, respectively, in the 3 groups. Only MADRS response for vortioxetine 20 mg significantly separated from placebo (P = .044

    Arhalofenate is a novel antiinflammatory uricosuric agent. The objective of this study was to evaluate its antiflare activity in patients with gout. This was a 12-week, randomized, double-blind, controlled phase IIb study. Eligible patients had had ≥3 flares of gout during the previous year, had discontinued urate-lowering therapy and colchicine, and had a serum uric acid (UA) level of 7.5-12 mg/dl. Patients were randomly assigned at a 2:2:2:2:1 ratio to receive 600 mg arhalofenate, 800 mg arhalofenate, 300 mg allopurinol, 300 mg allopurinol plus 0.6 mg colchicine, or placebo once a day. The primary outcome measure was the flare incidence (number of flares divided by time of exposure). The serum UA level was a secondary outcome measure. A total of 239 gout patients were randomized and took at least 1 dose of study medication. The primary outcome measure comparing flare incidence between 800 mg arhalofenate and 300 mg allopurinol was achieved, with a 46% decrease in the 800 mg arhalofenate group (0.66 versus 1.24; P = 0.0056). Treatment with 800 mg arhalofenate was also significantly better than placebo (P = 0.049) and not significantly different from treatment with 300 mg allopurinol plus 0.6 mg colchicine (P = 0.091). Mean changes in serum UA level were -12.5% with 600 mg arhalofenate and -16.5% with 800 mg arhalofenate (P = 0.001 and P = 0.0001, respectively, versus -0.9% with placebo). There were no meaningful differences in adverse events (AEs) between groups, and there were no serious AEs related to arhalofenate. Urinary calculus occurred in 1 patient receiving 300 mg allopurinol. No abnormal serum creatinine values >1.5-fold the baseline value were observed in the arhalofenate-treated groups. Arhalofenate at a dosage of 800 mg decreased gout flares significantly compared to allopurinol at a dosage of 300 mg. Arhalofenate was well tolerated and appeared safe. Arhalofenate is the first urate-lowering antiflare therapy. © 2016 The Authors

    Gastrointestinal (GI) disturbances such as diarrhea and flatulence are the most frequent adverse effects associated with miglustat therapy in type 1 Gaucher disease (GD1) and Niemann-Pick disease type C (NP-C), and the most common recorded reason for stopping treatment during clinical trials and in clinical practice settings. Miglustat-related GI disturbances are thought to arise from the inhibition of intestinal disaccharidases, mainly sucrase isomaltase. We report the effects of a co-administered dietary probiotic, S. boulardii, on the GI tolerability of miglustat in healthy adult subjects. In a double-blind, placebo-controlled, two-period, two-treatment cross-over trial, healthy adult male and female subjects were randomly allocated to treatment sequences, A-B and B-A (treatment A - miglustat 100 mg t.i.d. + placebo; treatment B - miglustat 100 mg t.i.d. + S. boulardii [500 mg, b.i.d.]). GI tolerability data were collected in patient diaries. The primary endpoint was the total number of 'diarrhea days' (≥3 loose stools within a 24-h period meeting Bristol Stool Scores [BSS] 6-7) based on WHO criteria. Secondary endpoints comprised numerous other diarrhea and GI tolerability indices. Twenty-one subjects received randomized therapy in each treatment sequence (total N = 42), and overall, 37 (88 %) subjects completed the study. The total number of diarrhea days was placebo (1.3 [2.4] days), but the paired treatment difference was not statistically significant (-0.5 [2.4] days; p = 0.159). However, a significant treatment difference (-0.7 [1.9]; p placebo (82 %) than with miglustat + S. boulardii (73 %). There were no between-treatment differences in miglustat pharmacokinetics. Although the primary endpoint was not met, the results of the post-hoc analysis suggest that co-administration of miglustat with S. boulardii might improve GI tolerability.

    Background Human skin aging is a multifactorial and complex biological process affecting the different skin constituents. Even if the skin aging mechanism is not yet fully unravelled is evident that epidermis loses the principal molecule responsible for binding and retaining water molecules, resulting in loss of skin moisture and accounting for some of the most striking alterations of the aged skin. Objectives This Study investigated the cosmetic filling efficacy of Fillerina® in decreasing the skin aging signs and in improving facial volume deficiencies. Methods A placebo-controlled, double-blind, randomized clinical trial was carried out on 40 healthy female subjects showing mild to moderate clinical signs of skin aging. The effect of the treatment on skin surface and on face volumes was assessed both in the short-term (3 h after a single product application) and in the long-term (7, 14, and 30 days after continuative daily use). Results Three hours after a single application and after 7, 14, and 30 days of treatment the lips volume was increased by 8.5%, 11.3%, 12.8%, and 14.2%. After 7, 14, and 30 days: (1) skin sagging of the face contours was decreased by −0.443 ± 0.286, −1.124 ± 0.511, and −1.326 ± 0.649 mm, respectively; (2) skin sagging of the cheekbones contours was decreased by −0.989 ± 0.585, −2.500 ± 0.929, and −2.517 ± 0.927 mm, respectively; (3) cheekbones volume was increased by 0.875 ± 0.519, 2.186 ± 0.781, and 2.275 ± 0.725 mm, respectively; (4) wrinkle volume was decreased by −11.3%, −18.4%, and −26.3%, respectively; and (5) wrinkle depth was decreased by −8.4%, −14.5%, and −21.8% respectively. Conclusion This study demonstrated the positive filling effect of Fillerina® in decreasing the clinical signs of skin aging and in improving the face volumes. PMID:25399620

    The prognosis of heart failure patients with reduced ejection fraction (HFrEF) in Japan remains poor, although there is growing evidence for increasing use of evidence-based pharmacotherapies in Japanese real-world HF registries. Sacubitril/valsartan (LCZ696) is a first-in-class angiotensin receptor neprilysin inhibitor shown to reduce mortality and morbidity in the recently completed largest outcome trial in patients with HFrEF (PARADIGM-HF trial). The prospectively designed phase III PARALLEL-HF (Prospective comparison of ARNI with ACE inhibitor to determine the noveL beneficiaL trEatment vaLue in Japanese Heart Failure patients) study aims to assess the clinical efficacy and safety of LCZ696 in Japanese HFrEF patients, and show similar improvements in clinical outcomes as the PARADIGM-HF study enabling the registration of LCZ696 in Japan. This is a multicenter, randomized, double-blind, parallel-group, active controlled study of 220 Japanese HFrEF patients. Eligibility criteria include a diagnosis of chronic HF (New York Heart Association Class II-IV) and reduced ejection fraction (left ventricular ejection fraction ≤35%) and increased plasma concentrations of natriuretic peptides [N-terminal pro B-type natriuretic peptide (NT-proBNP) ≥600pg/mL, or NT-proBNP ≥400pg/mL for those who had a hospitalization for HF within the last 12 months] at the screening visit. The study consists of three phases: (i) screening, (ii) single-blind active LCZ696 run-in, and (iii) double-blind randomized treatment. Patients tolerating LCZ696 50mg bid during the treatment run-in are randomized (1:1) to receive LCZ696 100mg bid or enalapril 5mg bid for 4 weeks followed by up-titration to target doses of LCZ696 200mg bid or enalapril 10mg bid in a double-blind manner. The primary outcome is the composite of cardiovascular death or HF hospitalization and the study is an event-driven trial. The design of the PARALLEL-HF study is aligned with the PARADIGM-HF study and aims to assess

    This randomized, double-blind, multi-center, non-inferiority trial was conducted to assess the efficacy and safety of a cross-linked hyaluronate (XLHA, single injection form) compared with a linear high molecular hyaluronate (HMWHA, thrice injection form) in patients with symptomatic knee osteoarthritis. Two hundred eighty seven patients with osteoarthritis (Kellgren-Lawrence grade I to III) were randomized to each group. Three weekly injections were given in both groups but two times of saline injections preceded XLHA injection to maintain double-blindness. Primary endpoint was the change of weight-bearing pain (WBP) at 12 weeks after the last injection. Secondary endpoints included Western Ontario and McMaster Universities Osteoarthritis index; patient's and investigator's global assessment; pain at rest, at night, or in motion; OMERACT-OARSI responder rate; proportion of patients achieving at least 20 mm or 40% decrease in WBP; and rate of rescue medicine use and its total consumption. Mean changes of WBP at 12 weeks after the last injection were -33.3 mm with XLHA and -29.2 mm with HMWHA, proving non-inferiority of XLHA to HMWHA as the lower bound of 95% CI (-1.9 mm, 10.1 mm) was well above the predefined margin (-10 mm). There were no significant between-group differences in all secondary endpoints. Injection site pain was the most common adverse event and no remarkable safety issue was identified. This study demonstrated that a single injection of XLHA was non-inferior to three weekly injections of HMWHA in terms of WBP reduction, and supports XLHA as an effective and safe treatment for knee osteoarthritis.

    Diuretics are recommended to treat volume overload with heart failure (HF), however, they may cause serum electrolyte imbalance, limiting their use. Moreover, patients with advanced HF could poorly respond to these diuretics. In this study, we evaluated the efficacy and safety of Tolvaptan, a competitive vasopressin V2-receptor antagonist developed as a new drug to treat volume overload in HF patients. A phase III, multicenter, randomized, double-blind, placebo-controlled parallel study was performed to assess the efficacy and safety of tolvaptan in treating HF patients with volume overload despite the use of conventional diuretics. One hundred and ten patients were randomly assigned to receive either placebo or 15 mg/day tolvaptan for 7 consecutive days. Compared with placebo, tolvaptan administered for 7 days significantly reduced body weight and improved symptoms associated with volume overload. The safety profile of tolvaptan was considered acceptable for clinical use with minimal adverse effects. Tolvaptan reduced volume overload and improved congestive symptoms associated with HF by a potent water diuresis (aquaresis).

To assess the efficacy and safety of topical brimonidine tartrate gel 0.5% for the treatment of erythema of rosacea. Both studies were randomized, double-blind, and vehicle-controlled, with identical design. Subjects with moderate to severe erythema of rosacea were randomized 1:1 to apply topical brimonidine tartrate gel 0.5% or vehicle gel once-daily for 4 weeks, followed by a 4-week follow-up phase. Evaluations included severity of erythema based on Clinician's Erythema Assessment and Patient's Self-Assessment, as well as adverse events. Topical brimonidine tartrate gel 0.5% was significantly more efficacious than vehicle gel throughout 12 hours on days 1, 15, and 29, with significant difference observed as early as 30 minutes after the first application on day 1 (all Pbrimonidine tartrate gel 0.5% than for vehicle; however, most of the adverse events were dermatological, mild, and transient in nature. These data generated in controlled trials may be different from those in clinical practice. Once-daily brimonidine tartrate gel 0.5% has a good safety profile and provides significantly greater efficacy relative to vehicle gel for the treatment of moderate to severe erythema of rosacea, as early as 30 minutes after application.

    SMOFlipid 20% is an intravenous lipid emulsion (ILE) containing soybean oil, medium-chain triglycerides, olive oil, and fish oil developed to provide energy, essential fatty acids (FAs), and long-chain ω-3 FAs as a mixed emulsion containing α-tocopherol. The aim was to assess the efficacy and safety of this new ILE in pediatric patients receiving home parenteral nutrition (HPN) compared with soybean oil emulsion (SOE). This single-center, randomized, double-blind study included 28 children on HPN allocated to receive either SMOFlipid 20% (n = 15) or a standard SOE (Intralipid 20%, n = 13). ILE was administered 4 to 5 times per week (goal dose, 2.0 g/kg/d) within a parenteral nutrition regimen. Assessments, including safety and efficacy parameters, were performed on day 0 and after the last study infusion (day 29). Lipid peroxidation was determined by measurement of thiobarbituric acid reactive substances (TBARS). There were no significant differences in laboratory safety parameters, including liver enzymes, between the groups on day 29. The mean ± standard deviation changes in the total bilirubin concentration between the initial and final values (day 29 to day 0) were significantly different between groups: SMOFlipid group -1.5 ± 2.4 µmol/L vs SOE group 2.3 ± 3.5 µmol/L, P oil, was safe and well tolerated, decreased plasma bilirubin, and increased ω-3 FA and α-tocopherol status without changing lipid peroxidation.

S-flurbiprofen plaster (SFPP has shown dramatic improvement in percutaneous absorption results from animal and clinical studies. In this study, the efficacy and safety of SFPP were compared with placebo in patients with knee osteoarthritis (OA to determine its optimal dose. This was a multicenter, randomized, double-blind, parallel-group comparative study. Patients and methods: Enrolled 509 knee OA patients were treated with placebo or SFPP at 10, 20, or 40 mg applied on the affected site once daily for 2 weeks. The primary endpoint for efficacy was improvement in knee pain on rising from the chair assessed by visual analog scale (VAS. The other endpoints were clinical symptoms, pain on walking, and global assessment by both investigator and patient. Safety was evaluated by observing adverse events (AEs. Results: VAS change in knee pain from baseline to trial end was dose-dependent, least squares mean was 29.5, 31.5, 32.0, and 35.6 mm in placebo and SFPP 10, 20, and 40 mg, respectively. A significant difference was observed between placebo and SFPP 40 mg (P=0.001. In contrast, the effect of SFPP at a dose ≤20 mg was not significantly different from that of placebo. The proportion of the patients who achieved 50% pain relief was 72.4% in 40 mg and 51.2% in placebo (P<0.001. In all other endpoints, SFPP 40 mg showed significant improvement compared with placebo.

    Probiotic organisms have shown promise in treating diseases. Previously, we have reported on the efficacy of microencapsulated Lactobacillus reuteri NCIMB 30242 in a yogurt formulation at lowering serum cholesterol levels in otherwise healthy hypercholesterolemic adults. This study investigates the safety and toxicology of oral ingestion of microencapsulated L. reuteri NCIMB 30242 in a yogurt formulation. A randomized group of 120 subjects received a dose of 5 × 10(10) CFU microencapsulated L. reuteri NCIMB 30242 in yogurt (n=59) or placebo yogurt (n=61) twice/day for 6 weeks. Clinical chemistry and hematological parameters of safety were analyzed. Fecal samples were collected at these time points for the analysis of deconjugated bile acids. The frequency, duration and intensity of adverse events (AEs) and clinical significance of safety parameters were recorded for both groups. No clinically significant differences between the probiotic yogurt and placebo yogurt treated groups were detected in either the blood clinical chemistry or hematology results and there was no significant increase in fecal deconjugated bile acids (P>0.05) between treated and control groups. The frequency and intensity of AEs was similar in the two groups. These results demonstrate the safe use of this formulation in food. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background We report the safety findings from a 3-year phase 3 study (NCT00205777 of bazedoxifene, a novel selective estrogen receptor modulator under development for the prevention and treatment of postmenopausal osteoporosis. Methods Healthy postmenopausal osteoporotic women (N = 7,492; mean age, 66.4 years were randomized to daily doses of bazedoxifene 20 or 40 mg, raloxifene 60 mg, or placebo for 3 years. Safety and tolerability were assessed by adverse event (AE reporting and routine physical, gynecologic, and breast examination. Results Overall, the incidence of AEs, serious AEs, and discontinuations due to AEs in the bazedoxifene groups was not different from that seen in the placebo group. The incidence of hot flushes and leg cramps was higher with bazedoxifene or raloxifene compared with placebo. The rates of cardiac disorders and cerebrovascular events were low and evenly distributed among groups. Venous thromboembolic events, primarily deep vein thromboses, were more frequently reported in the active treatment groups compared with the placebo group; rates were similar with bazedoxifene and raloxifene. Bazedoxifene showed a neutral effect on the breast and an excellent endometrial safety profile. The incidence of fibrocystic breast disease was lower with bazedoxifene 20 and 40 mg versus raloxifene or placebo. Reductions in total and low-density lipoprotein levels and increases in high-density lipoprotein levels were seen with bazedoxifene versus placebo; similar results were seen with raloxifene. Triglyceride levels were similar among groups. Conclusion Bazedoxifene showed a favorable safety and tolerability profile in women with postmenopausal osteoporosis.

    The study goal was to determine the efficacy and safety of an optimal dose of Evekeo, racemic amphetamine sulfate, 1:1 d-amphetamine and l-amphetamine (R-AMPH), compared to placebo in treating children with attention-deficit/hyperactivity disorder (ADHD) in a laboratory classroom setting. A total of 107 children ages 6-12 years were enrolled in this multicenter, dose-optimized, randomized, double-blind, placebo-controlled crossover study. After 8 weeks of open-label dose optimization, 97 subjects were randomized to 2 weeks of double-blind treatment in the sequence of R-AMPH followed by placebo (n=47) or placebo followed by R-AMPH (n=50). Efficacy measures included the Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) Rating Scale and Permanent Product Measure of Performance (PERMP) administered predose and at 0.75, 2, 4, 6, 8, and 10 hours postdose on 2 laboratory classroom days. Safety assessments included physical examination, chemistry, hematology, vital signs, and treatment-emergent adverse events (TEAEs). Compared to placebo, a single daily dose of R-AMPH significantly improved SKAMP-Combined scores (p<0.0001) at each time point tested throughout the laboratory classroom days, with effect onset 45 minutes postdose and extending through 10 hours. R-AMPH significantly improved PERMP number of problems attempted and correct (p<0.0001) throughout the laboratory classroom days. During the twice-daily dose-optimization open-label phase, improvements were observed with R-AMPH in scores of the ADHD-Rating Scale IV and Clinical Global Impressions Severity and Improvement Scales. TEAEs and changes in vital signs associated with R-AMPH were generally mild and not unexpected. The most common TEAEs in the open-label phase were decreased appetite (27.6%), upper abdominal pain (14.3%), irritability (14.3%), and headache (13.3%). Compared to placebo, R-AMPH was effective in treating children aged 6-12 years with ADHD, beginning at 45 minutes and continuing through 10 hours

    This randomized, double-blind study compared the efficacy and safety of blonanserin and risperidone to treat Chinese schizophrenia patients aged ≥18 and risperidone using a gradual dose-titration method (blonanserin tablets: 8-24 mg/day; risperidone tablets: 2-6 mg/day), twice daily. Treatment populations consisted of 128 blonanserin-treated patients and 133 risperidone-treated patients. Intention-to-treat analysis was performed using the last observation carried forward method. Reductions of PANSS total scores by blonanserin and risperidone treatment were -30.59 and -33.56, respectively. Risperidone treatment was associated with elevated levels of serum prolactin (67.16% risperidone versus 52.31% blonanserin) and cardiac-related abnormalities (22.39% risperidone versus 12.31% blonanserin), and blonanserin patients were more prone to extrapyramidal side effects (48.46% blonanserin versus 29.10% risperidone). In conclusion, blonanserin was as effective as risperidone for the treatment of Chinese patients with schizophrenia. The overall safety profiles of these drugs are comparable, although blonanserin was associated with a higher incidence of EPS and risperidone was associated with a higher incidence of prolactin elevation and weight gain. Thus, blonanserin is useful for the treatment of Chinese schizophrenia patients. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Patients with reactive airways are at risk for adenosine-induced bronchoconstriction, mediated via A(2B) and/or A(3) adenosine receptors. In this randomized, double-blind, placebo-controlled crossover trial, we examined the safety of regadenoson, a selective adenosine A(2A) receptor agonist, in patients with moderate chronic obstructive pulmonary disease (COPD) (n = 38) and patients with severe COPD (n = 11) with a baseline mean forced expiratory volume in 1 second (FEV(1)) of 1.74 +/- 0.50 L and 1.0 +/- 0.35 L, respectively, 37% of whom had dyspnea during activities of daily living. Patients receiving glucocorticoids or oxygen and those with pretreatment wheezing were included. Short-acting bronchodilators were withheld for at least 8 hours before treatment. No differences emerged between regadenoson and placebo on multiple lung function parameters, including repeated FEV(1) and forced vital capacity, respiratory rate, pulmonary examinations, and oxygen saturation. The mean maximum decline in FEV(1) was 0.11 +/- 0.02 L and 0.12 +/- 0.02 L (P = .55) in patients after regadenoson and placebo, respectively, and new-onset wheezing was observed in 6% and 12%, respectively (P = .33). No patient required acute treatment with bronchodilators or oxygen. This pilot study showed the overall safety of regadenoson in 49 compromised outpatients with clinically stable moderate and severe chronic obstructive pulmonary disease.

    The common cold, the most prevalent contagious viral disease in humans still lacks a safe and effective antiviral treatment. Iota-Carrageenan is broadly active against respiratory viruses in-vitro and has an excellent safety profile. This study investigated the efficacy and safety of an Iota-Carrageenan nasal spray in patients with common cold symptoms. In a randomized, double-blind, placebo-controlled exploratory trial, 35 human subjects suffering from early symptoms of common cold received Iota-Carrageenan (0.12%) in a saline solution three times daily for 4 days, compared to placebo. Administration of Iota-Carrageenan nasal spray reduced the symptoms of common cold (p = 0.046) and the viral load in nasal lavages (p = 0.009) in patients with early symptoms of common cold. Pro-inflammatory mediators FGF-2, Fractalkine, GRO, G-CSF, IL-8, IL-1alpha, IP-10, IL-10, and IFN-alpha2 were reduced in the Iota-Carrageenan group. Iota-Carrageenan nasal spray appears to be a promising treatment for safe and effective treatment of early symptoms of common cold. Larger trials are indicated to confirm the results.

    Two blinded single-dose studies randomized children 6 months to 11 years old with fever to receive ibuprofen (IBU) pediatric suspension 7.5 mg/kg or acetaminophen (APAP) suspension 10 to 15 mg/kg. The primary efficacy parameter was time-weighted sum of temperature differences (TWSTD) from baseline through 8 hours for each study. Secondary end points included TWSTD from baseline through 6 hours, time to onset and duration of temperature control, and proportion with temperature control. Studies were pooled for post hoc analyses of efficacy and adverse event end points. The primary efficacy parameter significantly favored IBU over APAP in study 1 and the pooled analysis (both P children, with a comparable safety profile.

    To compare the efficacy and safety of a new low-dose oral contraceptive pill (YAZ) containing drospirenone 3 mg and ethinylestradiol 20 µg with placebo in reducing symptoms of premenstrual dysphoric disorder (PMDD). This multicenter, double- blind, randomized clinical trial consisted of 2 run- in and 3 treatment cycles (84 days) with daily symptom charting; 187 women with symptoms of PMDD were randomized to either placebo group (n = 94) or YAZ group (n = 93), and assessed with daily record of severity of problems scale (DRSP) and clinical global impressions scale (CGI) before, during and after the treatments. Hormones were administered for 24 days, followed by 4 days of inactive pills. Compared with baseline level of DRSP, both groups got improvement after treatment; the YAZ group (median -28.7, range: -82.5 to 2.3) had greater improvement than that in the placebo group (median -23.7, range: -86.0 to 11.8), while there was not significant difference (P > 0.05). The main adverse effects of YAZ included intermenstrual bleeding [13% (12/93) versus 3% (3/94)], menorrhagia [9% (8/93) versus 1% (1/94)], nausea [5% (5/93) versus 4% (4/94)] and skin rash [4% (4/93) versus 2% (2/94)]. YAZ could improve symptoms of PMDD better than placebo, while without statistic significance in this study. The most common adverse effects are intermenstrual bleeding, menorrhagia, nausea and rash.

    Isotretinoin-Lidose, the first new formulation of isotretinoin in 30 years, differs from previously approved isotretinoin formulations in that it is less dependent on the presence of fat in the gut for absorption. Evaluate the safety profiles of isotretinoin-Lidose and food-dependent generic isotretinoin in the largest clinical study with isotretinoin-925 randomized patients from 49 study sites. Determine if the efficacy of this new formulation is noninferior to an existing isotretinoin. Multicenter, double-blind, randomized, parallel-group, noninferiority trial. Study medication was taken with meals twice daily for 20 weeks. Patients were followed for 4 weeks after the last dose. Safety evaluations included recordings of adverse events, assessments for depression, anxiety, emergent psychotic symptoms, and suicidal ideation/behavior, as well as DEXA and X-ray evaluations and changes in bone age. Two co-primary efficacy outcomes were measured to assess noninferiority: a) change in total nodular facial and truncal lesion count at from baseline to week 20 and b) percentage of patients who experienced at least 90% reduction in nodular facial and truncal lesion count from baseline to week 20. Although isotretinoin-Lidose can be taken without meals, it was given with food because the absorption of both formulations in the study had to be similar to detect noninferiority. The safety profile of the 2 formulations was comparable. Criteria for noninferiority for both co-primary efficacy outcomes were met based on predetermined margins. Safety and efficacy of isotretinoin-Lidose is similar and noninferior to food-dependent generic isotretinoin, respectively.

    To investigate the safety, tolerability, and pharmacokinetics of liraglutide in adolescents with obesity. This was a randomized, double-blind, placebo-controlled trial. Twenty-one subjects, aged 12-17 years and Tanner stage 2-5, with obesity (body mass index [BMI] corresponding to both a BMI ≥95th percentile for age and sex and to a BMI of ≥30 kg/m2 for adults; additionally, BMI was ≤45 kg/m2) were randomized (2:1) to receive 5 weeks of treatment with liraglutide (0.6 mg with weekly dose increase to a maximum of 3.0 mg for the last week) (n = 14) or placebo (n = 7). The primary endpoint was number of treatment-emergent adverse events (TEAEs). Secondary endpoints included safety measures, and pharmacokinetic and pharmacodynamic endpoints. All participants receiving liraglutide, and 4 receiving placebo (57.1%), had at least 1 TEAE. The most common TEAEs were gastrointestinal disorders. No severe TEAEs, TEAE-related withdrawals, or deaths occurred. Twelve hypoglycemic episodes occurred in 8 participants receiving liraglutide and 2 in 1 participant receiving placebo. No severe hypoglycemic episodes were reported. Liraglutide exposure in terms of trough concentration increased with dose, although dose proportionality was confounded by unexpectedly low trough concentration values at the 2.4 mg dose. Exposure in terms of model-derived area under the plasma concentration time curve from 0 to 24 hours after dose in steady state was similar to that in adults with obesity. Liraglutide had a similar safety and tolerability profile compared with adults when administered to adolescents with obesity, with no unexpected safety/tolerability issues. Results suggest that the dosing regimen approved for weight management in adults may be appropriate for use in adolescents. ClinicalTrials.gov: NCT01789086. Copyright © 2016 The Authors.

    Full Text Available OBJECTIVE: This study was aimed at evaluating the clinical efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS to treat muscle spasticity after brain injury (Chinese Clinical Trial Registry: ChiCTR-TRC-11001310. METHODS: A total of 60 patients with muscle spasticity after brain injury were randomized to the following 3 groups: 100, 2, and 0 Hz (sham TEAS. The acupoints Hegu (LI4--Yuji (LU10 and Zusanli (ST36--Chengshan (BL57 on the injured side were stimulated at 0, 2, or 100 Hz, 5 times per week for 4 weeks. The patients were followed up for 1 and 2 months after the treatments. The effects of the treatments on muscle spasticity at the wrist, thumb, the other 4 fingers, elbow, shoulder, knee, and ankle were evaluated by the Modified Ashworth Scale, and the effects on disability were assessed by the Disability Assessment Scale. The walking capability was evaluated by the Holden functional ambulation classification score. The overall performance was assessed by the Global Assessment Scale score and the improved Barthel Index. The safety of the treatments administered was also monitored. RESULTS: The wrist spasticity was significantly reduced from baseline at weeks 2, 3, and 4 of treatment and at the 1- and 2-month follow-up visits in the 100 Hz group (P < 0.01. Compared with 2 Hz or sham TEAS, 100 Hz TEAS decreased wrist spasticity at weeks 2, 3, and 4 of treatment and 1 month after treatment (P < 0.001. The other endpoints were not affected by the treatments. No treatment-emergent adverse events were reported during treatments and follow-up visits. CONCLUSIONS: TEAS appears to be a safe and effective therapy to relieve muscle spasticity after brain injury, although large-scale studies are required to further verify the findings.

    Secukinumab, an anti-interleukin-17A monoclonal antibody, improved the signs and symptoms of ankylosing spondylitis (AS) in two phase 3 studies (MEASURE 1 and MEASURE 2). Here, we present 52-week results from the MEASURE 3 study assessing the efficacy and safety of secukinumab 300 and 150 mg subcutaneous maintenance dosing, following an intravenous loading regimen. A total of 226 patients were randomized to intravenous secukinumab 10 mg/kg (baseline, weeks 2 and 4) followed by subcutaneous secukinumab 300 mg (IV-300 mg) or 150 mg (IV-150 mg) every 4 weeks, or matched placebo. Patients in the placebo group were re-randomized to subcutaneous secukinumab at a dose of 300 or 150 mg at week 16. The primary endpoint was the Assessment of SpondyloArthritis international Society criteria for 20% improvement (ASAS20) response rate at week 16 in the IV-300 mg or IV-150 mg versus placebo. Other endpoints assessed through week 52 included improvements in ASAS40, ASAS 5/6, Bath Ankylosing Spondylitis Disease Activity Index, and ASAS partial remission responses, as well as the change from baseline in high-sensitivity C-reactive protein levels. Statistical analyses followed a predefined hierarchical hypothesis testing strategy to adjust for multiplicity of testing, with non-responder imputation used for binary variables and mixed-model repeated measures for continuous variables. The primary efficacy endpoint was met; the ASAS20 response rate was significantly greater at week 16 in the IV-300 mg (60.5%; P < 0.01) and IV-150 mg (58.1%; P < 0.05) groups versus placebo (36.8%). All secondary endpoints were met at week 16, except ASAS partial remission in the IV-150 mg group. Improvements achieved with secukinumab in all clinical endpoints at week 16 were also sustained at week 52. Infections, including candidiasis, were more common with secukinumab than with placebo during the placebo-controlled period. During the entire treatment period, pooled incidence rates of Candida

    To show the superiority of 500 mg calcium dobesilate vs. placebo in reduction of edema of the lower limbs in patients with chronic venous insufficiency, Clinical, Etiological, Anatomical and Pathophysiological classes C3/C4. A total of 351 patients were randomized (n = 174 calcium dobesilate, n = 177 placebo). Active treatment was 500 mg calcium dobesilate, three times daily for 12 weeks, with a 12-week follow-up. At the end of treatment, the relative volume change in the most pathological leg was -0.6 ± 4.8% with calcium dobesilate compared to -0.3 ± 3.3% with placebo (p = 0.09). At the end of follow-up, this was -1.01 ± 5.4% for calcium dobesilate vs. -0.08 ± 3.5% for placebo (p = 0.002). Calcium dobesilate treatment resulted in no significant volume change in the most pathological leg between baseline and end of treatment. However, the calcium dobesilate group showed a significantly greater volume decrease in the most pathological leg at the end of follow-up. Calcium dobesilate was well-tolerated, with a safety profile consistent with previously published data. © The Author(s) 2015.

    Full Text Available Objective. The purpose of this study was to assess the efficacy and safety of Taeeumjowi-tang (TJ001 as well as to estimate obesity-related factors. Methods. This was a 12-week trial with 5 visits. A total of 102 participants of both genders were randomized to either TJ001 (n=57 group or the placebo group (n=55. Subjects were administered 7 g of either TJ001 or placebo 3 times a day. The primary outcome was a rate of subjects who lost 5% or more of initial weight. Secondary outcomes included anthropometric parameters, lipid profiles, and body fat composition. Results. The subject response rate of ≥5% weight loss compared to baseline was similar in both groups, and no statistically significant difference was observed (P=0.87. Changes in anthropometric parameters were greater during the first 4 weeks in the treatment group (P<0.0001. There were no significant changes in both within groups and between groups for lipid profile and body fat composition. No adverse event was reported in either group. Conclusion. Although the difference between the groups regarding a rate of subjects who lost 5% or more of initial weight did not show statistical significance, TJ001 appears to be beneficial in safely controlling weight.

    Furosemide is commonly prescribed for symptom relief in heart failure (HF) patients. Although few data support the continuous use of loop diuretics in apparently euvolemic HF patients with mild symptoms, there is concern about safety of diuretic withdrawal in these patients. The ReBIC-1 trial was designed to evaluate the safety and tolerability of withdrawing furosemide in stable, euvolemic, chronic HF outpatients. This multicenter initiative is part of the Brazilian Research Network in Heart Failure (ReBIC) created to develop clinical studies in HF and composed predominantly by university tertiary care hospitals. The ReBIC-1 trial is currently enrolling HF patients in NYHA functional class I-II, left ventricular ejection fraction ≤45%, without a HF-related hospital admission within the last 6 months, receiving a stable dose of furosemide (40 or 80 mg per day) for at least 6 months. Eligible patients will be randomized to maintain or withdraw furosemide in a double-blinded protocol. The trial has two co-primary outcomes: (1) dyspnea assessment using a visual-analogue scale evaluated at 4 time points and (2) the proportion of patients maintained without diuretics during the follow-up period. Total sample size was calculated to be 220 patients. Enrolled patients will be followed up to 90 days after randomization, and diuretic will be restarted if clinical deterioration or signs of congestion are detected. Pre-defined sub-group analysis based on NT-proBNP levels at baseline is planned. Evidence-based strategies aiming to simplify HF pharmacotherapy are needed in clinical practice. The ReBIC-1 trial will determine the safety of withdrawing furosemide in stable chronic HF patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To date, there is no commercially available vaccine to prevent infectious mononucleosis, a disease frequently induced by Epstein-Barr virus (EBV) infection in adolescents or adults devoid of preexisting immunity to the virus. A total of 181 EBV-seronegative, healthy, young adult volunteers were randomized in a double-blind fashion to receive either placebo or a recombinant EBV subunit glycoprotein 350 (gp350)/aluminum hydroxide and 3-O-desacyl-4'-monophosphoryl lipid A (AS04) candidate vaccine in a 3-dose regimen. The vaccine had demonstrable efficacy (mean efficacy rate, 78.0% [95% confidence interval {CI}, 1.0%-96.0%]) in preventing the development of infectious mononucleosis induced by EBV infection, but it had no efficacy in preventing asymptomatic EBV infection. One month after receipt of the final dose of gp350 vaccine, 98.7% of subjects showed seroconversion to anti-gp350 antibodies (95% CI, 85.5%-97.9%), and they remained anti-gp350 antibody positive for >18 months. Furthermore, there were no concerns regarding the safety or reactogenicity of the gp350/AS04 vaccine. These data support the clinical feasibility of using an EBV vaccine to prevent infectious mononucleosis. ClinicalTrials.gov identifier: NCT00430534.

    Patients with reactive airways are at risk for adenosine-induced bronchoconstriction, mediated via A(2B) and/or A(3) adenosine receptors. To examine the effects of regadenoson, a selective adenosine A(2A) receptor agonist, on airway resistance, we conducted a randomized, double-blind, placebo-controlled crossover trial in asthmatic patients with a positive adenosine monophosphate challenge test. The mean ratio of the forced expiratory volume in 1 second (FEV(1)) at each tested time point relative to the baseline FEV(1) was significantly higher after treatment with regadenoson compared with placebo from 10 to 60 minutes after treatment. One patient had a substantial but asymptomatic FEV(1) reduction (-36.2%) after regadenoson that reversed spontaneously. The most common adverse events with regadenoson were tachycardia (66%), dizziness (53%), headache (45%), and dyspnea (34%). The mean heart rate significantly increased with regadenoson (maximum of +10.4 beats/min) versus placebo. In this pilot safety study of 48 patients with mild or moderate asthma who had bronchial reactivity to adenosine monophosphate, regadenoson was safe and well tolerated.

One hundred sixty-one children were included in two subgroups: 4–8 years, average age 6.4 years, treated with verum or placebo and 6 months–<4 years, average age 1.8 years, treated only with verum. Pain reduction was measured from the time prior to administration to 10 or 30 minutes after. In addition, adverse events and local tolerability were evaluated. In group I, pain was reduced significantly after treatment with verum compared to placebo at both time points. In group II, the individual pain rating shift showed statistically significant lower pain after treatment. Only seven out of 161 patients reported an adverse event but none were classified as being related to the study medication. The local tolerability was assessed as very good in over 97% of cases. For painful sites in the oral cavity, a 2% lidocaine gel is a meaningful tool for short-term treatment in the paediatric population.

    Full Text Available Abstract Background Neramexane is a new substance that exhibits antagonistic properties at α9α10 cholinergic nicotinic receptors and N-methyl-D-aspartate receptors, suggesting potential efficacy in the treatment of tinnitus. Methods A total of 431 outpatients with moderate to severe subjective tinnitus (onset 3-18 months before screening were assigned randomly to receive either placebo or neramexane mesylate (25 mg/day, 50 mg/day and 75 mg/day for 16 weeks, with assessment at 4-week intervals. The primary (intention-to-treat efficacy analysis was based on the change from baseline in Week 16 in the total score of the adapted German short version of the validated Tinnitus Handicap Inventory questionnaire (THI-12. Results Compared with placebo, the largest improvement was achieved in the 50 mg/d neramexane group, followed by the 75 mg/d neramexane group. This treatment difference did not reach statistical significance at the pre-defined endpoint in Week 16 (p = 0.098 for 50 mg/d; p = 0.289 for 75 mg/d neramexane, but consistent numerical superiority of both neramexane groups compared with placebo was observed. Four weeks after the end of treatment, THI-12 scores in the 50 mg/d group were significantly better than those of the controls. Secondary efficacy variables supported this trend, with p values of Conclusions This study demonstrated the safety and tolerability of neramexane treatment in patients with moderate to severe tinnitus. The primary efficacy variable showed a trend towards improvement of tinnitus suffering in the medium- and high-dose neramexane groups. This finding is in line with consistent beneficial effects observed in secondary assessment variables. These results allow appropriate dose selection for further studies.

    Injectable hyaluronic acid is frequently used to correct volume loss in nasolabial folds. To compare the safety and efficacy of a novel hyaluronic acid gel to a non-animal stabilized hyaluronic acid (Comparator) gel for the correction of nasolabial folds (NLF). Qualified subjects had NLF with a Wrinkle Severity Rating Scale (WSRS) score of 3 or 4 (moderate or severe). NLFs were treated with Test Product on one side of the face and Comparator on the other side of the face (facial side randomly assigned). Improvement from baseline was evaluated at weeks 1, 2, 4, 12, and 24 weeks. The primary study endpoint was the mean change in WSRS score from baseline to week 24. The mean changes in WSRS score from baseline were 1.02 ±0.689 for Test Product and 0.91±0.762 for Comparator. The mean difference in change from baseline in WSRS scoring (Comparator minus Test Product) at week 24 was -0.11 (-0.225-0.001, 95% confidence interval [CI]). The upper boundary (0.001) of the 95% CI was less than the prespecified non-inferiority limit of 0.50, indicating that the Test Product was non-inferior to the Comparator. No subject discontinued the study due to adverse events. The Test Product is safe and non-inferior to the Comparator for the correction of nasolabial folds. The Test Product was associated with less swelling, pain, and overall severity of treatment-emergent adverse events than the Comparator. J Drugs Dermatol. 2018;17(1):66-73..

    The results of 3 proof-of-concept studies to evaluate carisbamate's efficacy and safety in treating neuropathic pain are presented. In studies 1 (postherpetic neuralgia, n = 91) and 2 (diabetic neuropathy, n = 137), patients received carisbamate 400 mg/day or placebo for 4 weeks and then crossed over to the other treatment for 4 weeks. In study 3 (diabetic neuropathy, higher carisbamate doses), patients (n = 386) were randomized (1:1:1:1) to receive either carisbamate 800 mg/day, 1200 mg/day, pregabalin 300 mg/day or placebo for 15 weeks. Primary efficacy end point was the mean of the last 7 average daily pain scores obtained on days the study drug was taken, for all 3 studies. Least square mean (95% CI) differences between carisbamate and placebo groups on the primary end point were as follows: study 1: -0.512 (-1.32, 0.29) carisbamate 400 mg/day; study 2: -0.307 (-0.94, 0.33) carisbamate 400 mg/day; and study 3: -0.51 (-1.10, 0.08), carisbamate 800 mg/day; -0.55 (-1.13, 0.04), carisbamate 1200 mg/day; and -0.43 (-1.01, 0.15), pregabalin 300 mg/day. Neither carisbamate (all 3 studies) nor pregabalin (study 3) significantly differed from placebo, although multiple secondary end points showed significant improvement in efficacy with carisbamate in studies 1 and 2. Dizziness was the only treatment-emergent adverse event occurring at ≥10% difference in carisbamate groups versus placebo (study 1: 12% vs. 1%; study 3: 14% vs. 4%; study 2: 1% vs. 2%). Carisbamate, although well tolerated, did not demonstrate efficacy in neuropathic pain across these studies, nor did the active comparator pregabalin (study 3). © 2013 World Institute of Pain.

    The aim of the study was to evaluate the efficacy and safety of a selective serotonin reuptake inhibitor (SSRI) drug dapoxetine in delaying ejaculation in patients with premature ejaculation (PE). A total of 212 potent men with PE were randomly assigned to receive 30 mg orally dapoxetine (group 1, N=106) twice daily or similar regimen of placebo (group 2, N=106) during a 12-week period for each agent. Pretreatment evaluation included history and physical examination, geometric mean intravaginal ejaculatory latency time (IELT, primary outcome measure), and International Index of Erectile Function (IIEF). The efficacy of two treatments was assessed every 2 weeks during treatment, at the end of study, and in 3-month follow-up after cessation of treatment. We measured geometric mean IELT. Thus, the IELT values were logarithmically transformed before statistical analysis, and the results are reported as fold increases from baseline with associated 95% confidence intervals (CI). The independent sample two-tailed t-test was used to compare the IELTs. At the end of 12-week treatment, the dapoxetine group had a 2.9- (95% CI, 1.84-4.16) fold increase of the geometric mean IELT, while after placebo the geometric mean IELT did not increase significantly (1.4-fold increase; 95% CI, 0.84-1.63) (p=0.001). The mean weekly intercourse episodes increased from pretreatment values of 1.16 and 1.14 to 2.2 and 1.4, for dapoxetine and placebo, respectively (p=0.04). Baseline mean intercourse satisfaction domain values of IIEF, 12 and 11, reached to 16 and 10 at the 12-week treatment in groups 1 and 2, respectively (p=0.04). At the end of 3-month follow-up period, the geometric mean IELT in dapoxetine and placebo group demonstrated 1.4- (95% CI, 0.66-1.46) and 1.3- (95% CI, 0.77-1.63) fold increase, respectively (p=0.1). Three-month intercourse satisfaction domain value of IIEF was 11 in group 1 and 10 in group 2 (p=0.1). Mean number of adverse events was 19 for dapoxetine and 7 for

    Considering the pandemic potential of avian influenza A/H5N1, development of an effective and well-tolerated vaccine is an essential part of pandemic preparedness plans. This phase III, randomized, double-blind study was conducted to assess the immunogenicity and safety profile of an alum-adjuvanted, whole virion, pre-pandemic influenza A/H5N1 vaccine (MG1109). Healthy individuals were randomly assigned, in a 3:1 ratio, to receive two doses of either MG1109 or placebo containing alum gel. Immunogenicity was determined by hemagglutination inhibition (HI) and microneutralization (MN) assays. Solicited and unsolicited adverse events were assessed after vaccination. Among 420 enrolled subjects, 418 were available for safety analysis, and 298 MG1109 recipients were available for per-protocol immunogenicity analyses. According to the HI assays, after two vaccine doses, all three of the Committee for Medicinal Products for Human Use (CHMP) criteria were met against the vaccine strain for all age groups: seroprotection rate = 74.8% (95% CI: 69.9 - 79.8), seroconversion rate = 67.8% (95% CI: 62.5-73.1), and geometric mean titer ratio (GMTR) = 5.9 (95% CI: 5.4 - 6.4). According to the MN assays, the GMTR was 2.4 (95% CI: 2.1 - 2.7) and 7.0 (95% CI: 6.3 - 7.9) three weeks after the first and second vaccine doses, respectively. Solicited local and systemic adverse events were mostly mild to moderate and were not significantly different between MG1109 and placebo recipients. In conclusion, two-dose administration of alum-adjuvanted H5N1 pre-pandemic influenza vaccine (MG1109) was highly immunogenic and tolerable in adults.

    Stress is a state of mental or emotional strain or tension, which can lead to underperformance and adverse clinical conditions. Adaptogens are herbs that help in combating stress. Ayurvedic classical texts, animal studies and clinical studies describe Ashwagandha as a safe and effective adaptogen. The aim of the study was to evaluate the safety and efficacy of a high-concentration full-spectrum extract of Ashwagandha roots in reducing stress and anxiety and in improving the general well-being of adults who were under stress. Single center, prospective, double-blind, randomized, placebo-controlled trial. A total of 64 subjects with a history of chronic stress were enrolled into the study after performing relevant clinical examinations and laboratory tests. These included a measurement of serum cortisol, and assessing their scores on standard stress-assessment questionnaires. They were randomized to either the placebo control group or the study drug treatment group, and were asked to take one capsule twice a day for a period of 60 days. In the study drug treatment group, each capsule contained 300 mg of high-concentration full-spectrum extract from the root of the Ashwagandha plant. During the treatment period (on Day 15, Day 30 and Day 45), a follow-up telephone call was made to all subjects to check for treatment compliance and to note any adverse reactions. Final safety and efficacy assessments were done on Day 60. t-test, Mann-Whitney test. The treatment group that was given the high-concentration full-spectrum Ashwagandha root extract exhibited a significant reduction (PAshwagandha group, relative to the placebo group. The adverse effects were mild in nature and were comparable in both the groups. No serious adverse events were reported. The findings of this study suggest that a high-concentration full-spectrum Ashwagandha root extract safely and effectively improves an individual's resistance towards stress and thereby improves self-assessed quality of life.

    Bilastine, a novel non-sedating second-generation H 1 -antihistamine, has been widely used in the treatment of allergic rhinoconjunctivitis and urticaria with a recommended dose of 20 mg once daily in most European countries since 2010. We evaluated its efficacy and safety in Japanese patients with chronic spontaneous urticaria (CSU). We conducted a multicenter, randomized, double-blind, placebo-controlled phase II/III study (trial registration No. JapicCTI-142574). Patients (age, 18-74 years) were randomly assigned to receive bilastine 20 mg, 10 mg or placebo once daily for 2 weeks. The primary efficacy endpoint was the change from baseline (Day -3 to 0) in total symptom score (TSS) at 2 weeks (Day 8-14), consisting of the itch and rash scores. A total of 304 patients were randomly allocated to bilastine 20 mg (101 patients), bilastine 10 mg (100 patients), and placebo (103 patients). The changes in TSS at 2 weeks were significantly decreased by bilastine 20 mg than did placebo (p bilastine 20 mg. Bilastine 10 mg also showed a significant difference from placebo (p bilastine showed significant improvement from Day 1, and were maintained during the treatment period. The Dermatology Life Quality Index scores were also improved in bilastine than in placebo. The bilastine treatments were safe and well tolerated. Two-week treatment with bilastine (20 or 10 mg) once daily was effective and tolerable in Japanese patients with CSU, demonstrating an early onset of action.

    Bilastine is a new non-sedative H(1) receptor antagonist, indicated for the treatment of allergic rhinitis (AR) (seasonal and perennial). To assess and compare the efficacy and safety of bilastine 20 mg vs. cetirizine 10 mg and placebo in relieving the symptoms of seasonal allergic rhinitis (SAR). Overall, 683 SAR patients, aged 12-70 years, were randomized to a double-blind treatment with bilastine 20 mg, cetirizine 10 mg or placebo, once daily for 14 days, in 61 centres across Europe. Patients recorded reflective (over the past 12 h) and instantaneous nasal (obstruction, rhinorrhoea, itching and sneezing) and non-nasal (ocular tearing, redness and itching) symptom scores (NSS and NNSS, respectively) twice daily, according to a pre-determined severity scale to provide reflective and instantaneous total symptom scores (TSS). The primary efficacy measure was the area under curve (AUC) of reflective TSS over 14 days of treatment (TSS-AUC(0-14 days)). Secondary efficacy measures included mean change from baseline in TSS, NSS and NNSS; discomfort caused by AR; and investigator's clinical global impression of the treatment. Safety was assessed according to adverse events (AEs), laboratory tests and electrocardiograms. The mean TSS-AUC(0-14 days) (score x day) was reduced in bilastine- and cetirizine-treated groups to a similar and significantly greater extent, compared with placebo (76.5, 72.3 and 100.6, respectively; Pbilastine and cetirizine were comparable and significantly superior to placebo for all secondary outcomes. While all treatments were well tolerated and the AE profiles of bilastine and placebo were similar, significantly fewer patients in the bilastine-treated group experienced somnolence (1.8%; PBilastine 20 mg once daily was significantly superior to placebo and comparable to cetirizine 10 mg in relieving symptoms of SAR, although it demonstrated a significantly better AE profile than cetirizine.

    Secondary hyperparathyroidism (SHPT) is a major complication associated with chronic kidney disease. We evaluated the efficacy and safety of etelcalcetide (ONO-5163/AMG 416), a novel intravenous calcimimetic, in Japanese haemodialysis patients with SHPT. In this phase 3, multicentre, randomized, double-blind, placebo-controlled, parallel-group study, etelcalcetide was administered three times per week at an initial dose of 5 mg, and subsequently adjusted to doses between 2.5 and 15 mg at 4-week intervals for 12 weeks. A total of 155 SHPT patients with serum intact parathyroid hormone (iPTH) levels ≥300 pg/mL were assigned to receive etelcalcetide (n = 78) or placebo (n = 77). The primary endpoint was the proportion of patients with decreased serum iPTH to the target range proposed by the Japanese Society for Dialysis Therapy (60-240 pg/mL). The major secondary endpoint was the proportion of patients with ≥30% reductions in serum iPTH from baseline. The proportion of patients meeting the primary endpoint was significantly higher for etelcalcetide (59.0%) versus placebo (1.3%). Similarly, the proportion of patients meeting the major secondary endpoint was significantly higher for etelcalcetide (76.9%) versus placebo (5.2%). Serum albumin-corrected calcium, phosphorus and intact fibroblast growth factor-23 levels were decreased in the etelcalcetide group. Nausea, vomiting and symptomatic hypocalcaemia were mild with etelcalcetide. Serious adverse events related to etelcalcetide were not observed. This study demonstrated the efficacy and safety of etelcalcetide. As the only available intravenous calcium-sensing receptor agonist, etelcalcetide is likely to provide a new treatment option for SHPT in haemodialysis patients.

    The most commonly impacted tooth is the third molar. An impacted third molar can ultimately cause acute pain, infection, tumors, cysts, caries, periodontal disease, and loss of adjacent teeth. Local anesthesia is employed for removing the third molar. This study aimed to evaluate the efficacy and safety of 2% lidocaine with 1:80,000 or 1:200,000 epinephrine for surgical extraction of bilateral impacted mandibular third molars. Sixty-five healthy participants underwent surgical extraction of bilateral impacted mandibular third molars in 2 separate visits while under local anesthesia with 2% lidocaine with different epinephrine concentration (1:80,000 or 1:200,000) in a double-blind, randomized, crossover trial. Visual analog scale pain scores obtained immediately after surgical extraction were primarily evaluated for the 2 groups receiving different epinephrine concentrations. Visual analog scale pain scores were obtained 2, 4, and 6 hours after administering an anesthetic. Onset and duration of analgesia, onset of pain, intraoperative bleeding, operator's and participant's overall satisfaction, drug dosage, and hemodynamic parameters were evaluated for the 2 groups. There were no statistically significant differences between the 2 groups in any measurements except hemodynamic factors (P >.05). Changes in systolic blood pressure and heart rate following anesthetic administration were significantly greater in the group receiving 1:80,000 epinephrine than in that receiving 1:200,000 epinephrine (P ≤.01). The difference in epinephrine concentration between 1:80,000 and 1:200,000 in 2% lidocaine liquid does not affect the medical efficacy of the anesthetic. Furthermore, 2% lidocaine with 1:200,000 epinephrine has better safety with regard to hemodynamic parameters than 2% lidocaine with 1:80,000 epinephrine. Therefore, we suggest using 2% lidocaine with 1:200,000 epinephrine rather than 2% lidocaine with 1:80,000 epinephrine for surgical extraction of impacted

    The goal for this study was to evaluate safety regarding anticoagulant activity and platelet activation during daily consumption of an aqueous cyanophyta extract (ACE), containing a high dose of phycocyanin. Using a randomized, double-blind, placebo-controlled study design, 24 men and women were enrolled after informed consent, and consumed either ACE (2.3 g/day) or placebo daily for 2 weeks. The ACE dose was equivalent to ∼1 g phycocyanin per day, chosen based on the highest dose Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration. Consuming ACE did not alter markers for platelet activation (P-selectin expression) or serum P-selectin levels. No changes were seen for activated partial thromboplastin time, thrombin clotting time, or fibrinogen activity. Serum levels of aspartate transaminase (AST) showed a significant reduction after 2 weeks of ACE consumption (P < .001), in contrast to placebo where no changes were seen; the difference in AST levels between the two groups was significant at 2 weeks (P < .02). Reduced levels of alanine transaminase (ALT) were also seen in the group consuming ACE (P < .08). Previous studies showed reduction of chronic pain when consuming 1 g ACE per day. The higher dose of 2.3 g/day in this study was associated with significant reduction of chronic pain at rest and when physically active (P < .05). Consumption of ACE showed safety regarding markers pertaining to anticoagulant activity and platelet activation status, in conjunction with rapid and robust relief of chronic pain. Reduction in AST and ALT suggested improvement in liver function and metabolism.

    The long-acting muscarinic antagonist (LAMA) umeclidinium (UMEC) and the combination of UMEC with the long-acting β2-agonist (LABA) vilanterol (UMEC/VI) are approved maintenance treatments for chronic obstructive pulmonary disease (COPD) in the US and EU. They are not indicated for the treatment of asthma. In this 52-week, double-blind, placebo-controlled, parallel-group safety study (GSK study DB2113359; NCT01316887), patients were randomized 2:2:1 to UMEC/VI 125/25 mcg, UMEC 125 mcg, or placebo. Study endpoints included adverse events (AEs), clinical chemistry and hematology parameters, vital signs, 12-lead, and 24-hour Holter electrocardiograms. COPD exacerbations and rescue medication use were assessed as safety parameters; lung function was also evaluated. The incidence of on-treatment AEs, serious AEs (SAEs), and drug-related AEs was similar between treatment groups (AEs: 52-58%; SAEs: 6-7%; drug-related AEs: 12-13%). Headache was the most common AE in each treatment group (8-11%). AEs associated with the LAMA and LABA pharmacologic classes occurred at a low incidence across treatment groups. No clinically meaningful effects on vital signs or laboratory assessments were reported for active treatments versus placebo. The incidences of atrial arrhythmias with UMEC/VI 125/25 mcg were similar to placebo; for UMEC 125 mcg, the incidences of ectopic supraventricular beats, sustained supraventricular tachycardia, and ectopic supraventricular rhythm were ≥2% greater than placebo. With active treatments, COPD exacerbations were fewer (13-15% of patients reporting ≥1 exacerbation) and on average less rescue medication was required (1.6-2.2 puffs/day) versus placebo (24% reporting ≥1 exacerbation, 2.6 puffs/day). Both active treatments improved lung function versus placebo. UMEC/VI 125/25 mcg and UMEC 125 mcg were well tolerated over 12 months in patients with COPD.

    Full Text Available Background: As of 2010, the rivastigmine patch was licensed for the treatment of Alzheimer’s disease (AD in 64 countries. Methods: This 24-week, multicenter, randomized, double-blind, placebo-controlled study evaluated the efficacy, safety and tolerability of the 5-cm2 (9-mg loading dose; 4.6 mg/24 h delivery rate and 10-cm2 (18-mg loading dose; 9.5 mg/24 h delivery rate rivastigmine patch in Japanese patients with AD. Results: In the primary analysis population (intent-to-treat last observation carried forward at week 24, delayed deterioration was seen with the 10-cm2 patch versus placebo on the Japanese version of the Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-J cog; p = 0.005 and the Japanese version of the Clinician’s Interview-Based Impression of Change plus Caregiver Input (CIBIC plus-J; p = 0.067. Participants receiving the rivastigmine patch showed numerically less decline versus placebo at week 24 on the CIBIC plus-J, although this did not reach statistical significance. Statistical significance for the CIBIC plus-J was met following adjustment for body weight and baseline Mini-Mental State Examination score as dynamic allocation factors (p = 0.042 and on the Disability Assessment for Dementia (DAD; p = 0.024 and Mental Function Impairment (MENFIS; p = 0.016 subscales. Serious adverse events were rare and were consistent with the known safety profile of the rivastigmine patch. Conclusion: The rivastigmine patch has a favorable efficacy and tolerability profile in Japanese patients with AD.

    The purpose of this study was to examine the efficacy and safety of adding ω-3 fatty acids to rosuvastatin in patients with residual hypertriglyceridemia despite statin treatment. This study was a multicenter, randomized, double-blind, placebo-controlled study. After a 4-week run-in period of rosuvastatin treatment, the patients who had residual hypertriglyceridemia were randomized to receive rosuvastatin 20 mg/d plus ω-3 fatty acids 4 g/d (ROSUMEGA group) or rosuvastatin 20 mg/d (rosuvastatin group) with a 1:1 ratio and were prescribed each medication for 8 weeks. A total of 201 patients were analyzed (mean [SD] age, 58.1 [10.7] years; 62.7% male). After 8 weeks of treatment, the percentage change from baseline in triglycerides (TGs) and non-HDL-C was significantly greater in the ROSUMEGA group than in the rosuvastatin group (TGs: -26.3% vs -11.4%, P fatty acids was greater when baseline TG or non-HDL-C levels were high and body mass index was low. The incidence of adverse events was not significantly different between the 2 groups. In patients with residual hypertriglyceridemia despite statin treatment, a combination of ω-3 fatty acids and rosuvastatin produced a greater reduction of TGs and non-HDL-C than rosuvastatin alone. Further study is needed to determine whether the advantages of this lipid profile of ω-3 fatty acids actually leads to the prevention of cardiovascular event.

    A new reduced-dose tetanus-diphtheria (Td) vaccine was developed in Korea, and phase I and II clinical trials were successfully undertaken. We conducted this double-blind, randomized, multicenter phase III clinical trial to assess the immunogenicity and safety of the new Td vaccine. Healthy adolescents 11-12 years of age were enrolled and randomized to receive the new Td vaccine (study group) or a commercially available Td vaccine (control group). Blood samples were collected prior to and 4 weeks after the vaccination. Between the study and control groups, seroprotection rate, booster response, and geometric mean titer of antibodies against diphtheria and tetanus toxoids were compared after the vaccination. All solicited and unsolicited adverse events and serious adverse events during the 6-week study period were monitored. A total of 164 adolescents received vaccination, and 156 of them were evaluated to assess immunogenicity. The seroprotection rate and geometric mean titer for antibodies against diphtheria were significantly higher in the study group, whereas those against tetanus were significantly higher in the control group. However, all seroprotection rates against diphtheria and tetanus in the study and control groups were high: 100% against diphtheria and tetanus in the study group, and 98.7% against diphtheria and 100% against tetanus in the control group. No significant differences in the frequency of solicited and unsolicited adverse events were observed between the two vaccine groups. The new Td vaccine is highly immunogenic and safe, and this new Td vaccine can be effectively used for preventing diphtheria and tetanus. Copyright © 2015. Published by Elsevier B.V.

    Solithromycin, a new macrolide, and the first fluoroketolide in clinical development, with activity against macrolide-resistant bacteria, was tested in 132 patients with moderate to moderately severe community-acquired bacterial pneumonia (CABP) in a multicenter, double-blind, randomized phase 2 study. Patients were enrolled and randomized (1:1) to either 800 mg solithromycin orally (PO) on day 1, followed by 400 mg PO daily on days 2 to 5, or 750 mg levofloxacin PO daily on days 1 to 5. Efficacy outcome rates of clinical success at the test-of-cure visit 4 to 11 days after the last dose of study drug were comparable in the intent-to-treat (ITT) (84.6% for solithromycin versus 86.6% for levofloxacin) and microbiological-intent-to-treat (micro-ITT) (77.8% for solithromycin versus 71.4% for levofloxacin) populations. Early response success rates at day 3, defined as improvement in at least two cardinal symptoms of pneumonia, were also comparable (72.3% for solithromycin versus 71.6% for levofloxacin). More patients treated with levofloxacin than with solithromycin experienced treatment-emergent adverse events (TEAEs) during the study (45.6% versus 29.7%). The majority of TEAEs were mild or moderate gastrointestinal symptoms and included nausea (1.6% for solithromycin; 10.3% for levofloxacin), diarrhea (7.8% for solithromycin; 5.9% for levofloxacin), and vomiting (0% for solithromycin; 4.4% for levofloxacin). Six patients, all of whom received levofloxacin, discontinued the study drug due to an adverse event. Solithromycin demonstrated comparable efficacy and favorable safety relative to levofloxacin. These findings support a phase 3 study of solithromycin for the treatment of CABP. (This study has been registered at ClinicalTrials.gov under registration no. NCT01168713.) PMID:23507282

    This phase II study assessed lenalidomide efficacy and safety. Three-phase core study: 14-day prerandomization, 12-week treatment, and 52-week open-label extension. Fourteen US centers from July 2005 to July 2007. Chronic lumbar radicular pain patients without history of nerve injury or deficit. Subjects were randomized (1:1) to double-blind treatment with lenalidomide 10 mg or placebo once daily for 12 weeks, followed by a 52-week open-label extension. A 12-week, single-center, randomized-withdrawal (1:2, lenalidomide:placebo), exploratory study with open-label extension was undertaken in 12 subjects from the core extension who were naïve to neuropathic medications and with at least a two-point decrease from baseline average daily Pain Intensity-Numerical Rating Scale score. Of 180 subjects enrolled, 176 had at least one postbaseline measure; 132 completed the 12-week treatment phase. In the core study, no statistically significant difference in Pain Intensity-Numerical Rating Scale mean change (-0.02, P  =   0.958) was observed at week 12 between lenalidomide and placebo; proportions achieving pain reduction at week 12 and other secondary measures were comparable between lenalidomide and placebo. In the exploratory study, week 12 mean changes in Pain Intensity-Numerical Rating Scale scores were -0.05 (lenalidomide: N = 3) and 2.11 (placebo: N = 8). Mean changes in Brief Pain Inventory-short form interference scores were -3.33 and 8.38, respectively; scores at six months were maintained or decreased in 10 of 12 subjects. While this study does not support lenalidomide use in an unselected lumbar radicular pain population, an immunomodulating agent may relieve pain in select subjects naïve to neuropathic pain medications.

    The widespread use of cyclosporine has improved the survival of cardiac transplant patients as a result of reduced morbidity and mortality from rejection and infection. The original oil-based form of cyclosporine demonstrated unpredictable absorption resulting in an increased frequency of acute and chronic rejection in patients with poor bioavailability. The primary end. points of the present, prospective, randomized multicenter, double-blind trial were to compare the efficacy of the micro-emulsion form of cycolsporine (CsA-NL) with the oil-based formulation as determined by cardiac allograft and recipient survival and the incidence and severity of the acute rejection episodes and to determine the safety and tolerability of CsA-NL compared with Sandimmune CsA-(SM) in the study population. The 6-month analysis of the study showed reduced number of CsA-NL patients requiring antilymphocyte antibody therapy for rejection, fewer International Society of Heart and Lung Transplantation grade > or =3A rejections in female patients and fewer infections. Our report represents the final analysis of the results 24 months after transplantation. A total of 380 patients undergoing de novo cardiac transplants at 24 centers in the United States, Canada, and Europe were enrolled in this double-blind, randomized trial evaluating the efficacy and safety of CsA-NL versus CsA-SM. Acute allograft rejection was diagnosed by endomyocardial biopsy and graded according to the International Society of Heart and Lung Transplantation nomenclature. Kaplan-Meier analysis and Fisher's exact test were used for comparisons between groups. After 24 months, allograft and recipient survival were identical in both groups. There were fewer CsA-NL patients (6.9%) requiring antilymphocyte antibody therapy for rejection than in the CsA-SM-treated patient group (17.7%, P=0.002). There were fewer discontinuations of study drug for treatment failures in the CsA-NL groups (7; 3.7%) compared with the Cs

    The study was designed to assess acceptability and side-effects of consumption of sacha inchi oil, rich in α-linolenic acid and sunflower oil, rich in linoleic acid, in adult human subjects. Thirty subjects received 10 or 15ml daily of sacha inchi or sunflower oil for 4months. Acceptability was assessed with daily self-report and with a Likert test at the end of the study. Safety was assessed with self- recording of side-effects and with hepatic and renal markers. Primary efficacy variables were the change in lipid profile. Subjects reported low acceptability of sacha inchi oil at week-1 (37.5%). However, since week-6, acceptability was significantly increased to 81.25-93.75%. No differences were observed in acceptability with respect to sex or oil volume (P>0.05). Most frequent adverse effects during first weeks of consuming sacha inchi oil or sunflower oil were nauseas. The side-effects were reduced with time. Biochemical markers of hepatic and kidney function were maintained unchanged. Serum total cholesterol and LDL cholesterol levels and arterial blood pressure were lowered with both oils (P<0.05). Higher HDL-cholesterol was observed with sacha inchi oil at month-4. In conclusion, sacha inchi oil consumed has good acceptability after week-1 of consumption and it is safety. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Objective. To investigate the safety (risk) and efficacy (benefit) of Echinacea purpurea extract in the prevention of common cold episodes in a large population over a 4-month period. Methods. 755 healthy subjects were allocated to receive either an alcohol extract from freshly harvested E. purpurea (95% herba and 5% root) or placebo. Participants were required to record adverse events and to rate cold-related issues in a diary throughout the investigation period. Nasal secretions were sampled at acute colds and screened for viruses. Results. A total of 293 adverse events occurred with Echinacea and 306 with placebo treatment. Nine and 10% of participants experienced adverse events, which were at least possibly related to the study drug (adverse drug reactions). Thus, the safety of Echinacea was noninferior to placebo. Echinacea reduced the total number of cold episodes, cumulated episode days within the group, and pain-killer medicated episodes. Echinacea inhibited virally confirmed colds and especially prevented enveloped virus infections (P therapy compliance and adherence to the protocol. Conclusions. Compliant prophylactic intake of E. purpurea over a 4-month period appeared to provide a positive risk to benefit ratio. PMID:23024696

    Necrotizing enterocolitis (NEC) is the most common acquired gastrointestinal disease in premature infants and has high mortality and morbidity. Endothelial nitric oxide is an important regulator of vascular perfusion and is synthetized from the amino acid L-arginine. Hypoargininemia is frequently observed in preterm neonates and may predispose them to NEC. Our objective was to determine the effect of enteral L-arginine supplementation on the incidence and severity of NEC in very low birth weight (VLBW) neonates. We conducted a parallel blind randomized pilot study, comprising VLBW neonates with birth weight ≤1500 g and gestational age ≤34 weeks. VLBW neonates were randomly assigned to receive enteral L-arginine supplementation (1.5 mmol/kg/d bid) between the 3rd and 28th day of life or placebo. Diagnosis and classification of NEC were done according to modified Bell's criteria. Eighty-three neonates were randomized to the arginine (n = 40) or placebo (n = 43) group. No adverse effects were observed in neonates receiving L-arginine supplementation. The incidence of NEC stage III was significantly lower in the arginine-supplemented group (2.5% vs 18.6%, P = .030). Enteral L-arginine supplementation of 1.5 mmol/kg/d bid can be safely administered in VLBW neonates from the 3rd to the 28th day of life. Enteral L-arginine supplementation appears to reduce the incidence of stage III NEC in VLBW infants. Larger studies are needed to further evaluate the effect of L-arginine supplementation in preventing NEC in VLBW infants.

    Patients undergoing spinal fusion surgery often experience severe pain during the first three postoperative days. The aim of this parallel-group randomized trial was to assess the effect of the long-duration opioid methadone on postoperative analgesic requirements, pain scores, and patient satisfaction after complex spine surgery. One hundred twenty patients were randomized to receive either methadone 0.2 mg/kg at the start of surgery or hydromorphone 2 mg at surgical closure. Anesthetic care was standardized, and clinicians were blinded to group assignment. The primary outcome was intravenous hydromorphone consumption on postoperative day 1. Pain scores and satisfaction with pain management were measured at postanesthesia care unit admission, 1 and 2 h postadmission, and on the mornings and afternoons of postoperative days 1 to 3. One hundred fifteen patients were included in the analysis. Median hydromorphone use was reduced in the methadone group not only on postoperative day 1 (4.56 vs. 9.90 mg) but also on postoperative days 2 (0.60 vs. 3.15 mg) and 3 (0 vs. 0.4 mg; all Pmethadone group at 21 of 27 assessments (all P = 0.001 to methadone group than in the hydromorphone group until the morning of postoperative day 3 (all P = 0.001 to methadone administration reduced postoperative opioid requirements, decreased pain scores, and improved patient satisfaction with pain management.

    The objective of this study was to compare the efficacy of valproate versus haloperidol in decreasing the agitation level in affected patients in the emergency department. We assigned 80 acutely agitated patients to receive either intravenous sodium valproate (20 mg/kg) or intramuscular haloperidol (5 mg/1 ml). Agitation was measured at baseline and 30 min after the first injection using the Agitation-Calmness Evaluation Scale (ACES), the Positive and Negative Syndrome Scale-Excited Component subscale, and the Agitated Behavior Scale. For 80 patients treated with sodium valproate, the mean ± SD dosage was 1541.5 ± 286 mg (range 940-2400). The mean postintervention ACES scores from baseline to 30 min after drug injection were 4.73 (SD = 1.93) for the valproate group and 5.45 (SD = 2.09) for the haloperidol group (P = 0.028). No significant differences were observed in terms of the mean changes 30 min after the intervention for two additional agitation scales. A larger proportion of patients in the haloperidol group experienced intense sedation (36.2%, P valproate group (2.5% for intense sedation, no patient for extrapyramidal symptoms). The findings suggest that in the clinical practice setting of emergency psychiatry, intravenous valproate is as effective as haloperidol in reducing agitation, with a better safety profile.

    cerebrolysin is a neuropeptide preparation mimicking the effects of neurotrophic factors. This subgroup analysis assessed safety and efficacy of Cerebrolysin in patients with moderate to moderately severe Alzheimer's disease (AD) (ITT data set: N = 133; MMSE: 14-20) included in a dose-finding study (ITT data set: N = 51; MMSE: 14-25). Results of the mild AD subgroup (ITT data set: N = 118; MMSE: 21-25) are also presented. patients with AD received 100 ml IV infusions of Cerebrolysin (10, 30 or 60 ml diluted in saline; N = 32, 34 and 35, respectively) or placebo (saline; N = 32) over twelve weeks (5 days per week for 4 weeks and 2 days per week for another 8 weeks). Primary efficacy criteria ADAS-cog+ (Alzheimer's Disease Assessment Scale Cognitive Subpart Modified) and CIBIC+ (Clinical Interview-based Impression of Change with Caregiver Input) were assessed 24 weeks after baseline. at week 24, Cerebrolysin improved the global clinical function significantly with all three dosages and induced significant improvements in cognition, initiation of activities of daily living (ADL) and neuropsychiatric symptoms at 10-, 30- and 60-ml doses, respectively. Treatment effects on total ADL and other secondary parameters (MMSE, Trail-making test) were not significant. Cerebrolysin was safe and well tolerated. these results demonstrate the efficacy of Cerebrolysin in moderate to moderately severe AD, showing dose-specific effects similar to those reported for patients with mild to moderate AD. The benefits of Cerebrolysin in advanced AD need to be confirmed in larger trials.

    To verify if the Bio-Manguinhos 17DD yellow fever vaccine (17DD-YFV) used in lower doses is as immunogenic and safe as the current formulation. Doses from 27,476 IU to 587 IU induced similar seroconversion rates and neutralizing antibodies geometric mean titers (GMTs). Immunity of those who seroconverted to YF was maintained for 10 mo. Reactogenicity was low for all groups. Young and healthy adult males (n = 900) were recruited and randomized into 6 groups, to receive de-escalating doses of 17DD-YFV, from 27,476 IU to 31 IU. Blood samples were collected before vaccination (for neutralization tests to yellow fever, serology for dengue and clinical chemistry), 3 to 7 d after vaccination (for viremia and clinical chemistry) and 30 d after vaccination (for new yellow fever serology and clinical chemistry). Adverse events diaries were filled out by volunteers during 10 d after vaccination. Volunteers were retested for yellow fever and dengue antibodies 10 mo later. Seropositivity for dengue was found in 87.6% of volunteers before vaccination, but this had no significant influence on conclusions. In young healthy adults Bio-Manguinhos/Fiocruz yellow fever vaccine can be used in much lower doses than usual. INTERNATIONAL REGISTER: ISRCTN 38082350.

    Full Text Available Joe A Vinson1, Bryan R Burnham3, Mysore V Nagendran31Chemistry Department, 2Psychology Department, University of Scranton, Scranton, PA, USA; 3Health Sciences Clinic, Bangalore, IndiaBackground: Adult weight gain and obesity have become worldwide problems. Issues of cost and potential side effects of prescription weight loss drugs have led overweight and obese adults to try nutraceuticals that may aid weight loss. One promising nutraceutical is green coffee extract, which contains high concentrations of chlorogenic acids hat are known to have health benefits and to influence glucose and fat metabolism. A 22-week crossover study was conducted to examine the efficacy and safety of a commercial green coffee extract product GCA™ at reducing weight and body mass in 16 overweight adults.Methods: Subjects received high-dose GCA (1050 mg, low-dose GCA (700 mg, or placebo in separate six-week treatment periods followed by two-week washout periods to reduce any influence of preceding treatment. Treatments were counterbalanced between subjects. Primary measurements were body weight, body mass index, and percent body fat. Heart rate and blood pressure were also measured.Results: Significant reductions were observed in body weight (-8.04 ± 2.31 kg, body mass index (-2.92 ± 0.85 kg/m2, and percent body fat (-4.44% ± 2.00%, as well as a small decrease in heart rate (-2.56 ± 2.85 beats per minute, but with no significant changes to diet over the course of the study. Importantly, the decreases occurred when subjects were taking GCA. Body mass index for six subjects shifted from preobesity to the normal weight range (<25.00 kg/m2.Conclusion: The results are consistent with human and animal studies and a meta-analysis of the efficacy of green coffee extract in weight loss. The results suggest that GCA may be an effective nutraceutical in reducing weight in preobese adults, and may be an inexpensive means of preventing obesity in overweight adults

    This randomized, double-blind, phase III study evaluated the efficacy and safety of once-daily treatment with alogliptin (25 mg once daily), alone or with metformin hydrochloride (500 mg once daily or 250 mg twice daily), in Japanese patients with type 2 diabetes. The primary endpoint was change in glycated haemoglobin (HbA1c) from baseline to the end of treatment (week 24). The least squares (LS) mean (standard error) change in HbA1c from baseline to the end of treatment (week 24) was 0.16 (0.072)% in alogliptin alone, -0.49 (0.049)% in alogliptin/metformin once daily, and -0.60 (0.049)% in alogliptin/metformin twice daily. The LS mean difference in HbA1c change from baseline between alogliptin/metformin once daily and alogliptin alone (alogliptin/metformin once daily minus alogliptin alone) was -0.65% (95% confidence interval [CI] -0.821, -0.480) and between alogliptin/metformin once daily and twice daily (once daily minus twice daily) was 0.11% (95% CI -0.026, 0.247). The overall frequency of adverse events was similar among the groups. This study showed that the efficacy of alogliptin/metformin once daily was superior to alogliptin alone and non-inferior to alogliptin/metformin twice daily, and that alogliptin/metformin once daily was safe and well tolerated in Japanese patients with type 2 diabetes. © 2016 John Wiley & Sons Ltd.

    Full Text Available Context and Objectives: The number of people with diabetes is increasing exponentially in India. Owing to a unique "Asian Indian Phenotype," Indians develop diabetes a decade earlier and have an earlier onset of complications than Western populations. Therefore, it is essential to evaluate more effective treatment strategies at an earlier stage of disease progression, such as initial combination therapy, in Indian patients. In this study, we evaluated the efficacy and safety of initial combination therapy with linagliptin plus metformin in comparison to linagliptin or metformin monotherapy in Indian patients with type 2 diabetes mellitus. Methods: This is a subgroup analysis of Indian patients who participated in a Phase III, 24-week, double-blind, placebo-controlled, trial. Overall, 249 Indian patients were randomized to one of six treatment arms (Two free combination therapy arms: Linagliptin 2.5 mg twice daily [bid] + either low [500 mg, n = 36] or high [1000 mg, n = 44] dose metformin bid and four monotherapy arms: Linagliptin 5 mg once daily [qd, n = 40], metformin 500 mg [n = 49] or 1000 mg bid [n = 45], or placebo [n = 23]. Results: The placebo-corrected mean change in glycated hemoglobin from baseline (8.9% to week 24 was −1.83% for linagliptin + metformin 1000 mg bid; −1.46% for linagliptin + metformin 500 mg bid; −1.30% for metformin 1000 mg bid; −1.00% for metformin 500 mg bid; and −0.77% for linagliptin 5 mg qd. None of the patients in the combination therapy arms had hypoglycemia, whereas there was one event in the metformin 1000 mg bid arm. Rates of adverse event were similar across various treatments. Conclusions: In this subgroup analysis of Indian patients, initial combination therapy with linagliptin + metformin was more efficacious in improving glycemic control than the monotherapy arms, with a comparable tolerability profile. The results were comparable to the overall population.

    Papulopustular acne rosacea is a chronic inflammatory condition which can be difficult to treat. Many patients are unwilling to use systemic medications, and single topical agents alone may not address all the symptoms of rosacea. A combination topical clindamycin phosphate 1.2% and tretinoin 0.025% gel is efficacious for acne vulgaris, and may be helpful for rosacea, since acne vulgaris and rosacea shares many similar clinical and histologic features. To assess the preliminary efficacy and safety of a combination gel consisting of clindamycin phosphate 1.2% and tretinoin 0.025% on papulopustular rosacea after 12 weeks of usage. Randomized, double-blind, placebo controlled two site study of 79 participants with moderate to severe papulopustular acne rosacea using both physician and subjects' validated assessment tools. Primary endpoint consisted of statistically significant reduction in absolute papule or pustule count after 12 weeks of usage. There was no significant difference in papule/pustule count between placebo and treated groups after 12 weeks (P=0.10). However, there was nearly significant improvement in physicians' assessments of the telangiectasia component of rosacea (P=0.06) and erythematotelangiectatic rosacea subtype (P=0.05) in treated versus placebo group after 12 weeks. The only significant adverse event different was facial scaling, which was significantly increased in treated group (P=0.01), but this did not result in discontinuation of study drug. A combination gel of clindamycin phosphate 1.2% and tretinoin 0.025% may improve the telangiectatic component of rosacea and appears to better treat the erythemotelangiectatic subtype of rosacea rather than papulopustular subtype. Our preliminary study suggests that future studies with much larger sample size might confirm our findings.

    The primary objective of this study was to demonstrate efficacy of Ritalin(®) LA 20 mg by showing superiority to placebo and noninferiority to Medikinet(®) Retard in a laboratory classroom setting. Secondary objectives included safety/tolerability and further efficacy parameters. A total of 147 children with attention-deficit/hyperactivity disorder (ADHD) diagnosed by the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) and aged 6-14 (81% males) and known to be methylphenidate (MPH) responders were enrolled in this multicenter, double-blind, randomized, placebo/active-controlled, three-period (7 days each) crossover study. The Swanson, Kotlin, Agler, M-Flynn, and Pelham (SKAMP) scale was used for efficacy ratings. The mean of SKAMP Combined ratings performed at 10:30 a.m., at 12:00 a.m., and at 1:30 p.m. was defined as the primary parameter. In all, 146 patients completed all treatment periods. Intensity and frequency of adverse events were comparable between the two formulations. Ritalin(®) LA demonstrated superiority compared to placebo (p<0.0001). The observed difference in the SKAMP scores between Ritalin(®) LA and Medikinet(®) Retard between the hours 1.5 until 4.5 did not exceed the noninferiority margin (p=0.0003); therefore, the difference is regarded as not clinically relevant. Similar results were obtained for the secondary efficacy variables. Ritalin(®) LA is an efficacious, well-tolerated treatment option for children aged 6-14 with ADHD.

    To compare efficacy and safety of tapentadol prolonged-release (PR) and oxycodone-controlled release (CR) in moderate-to-severe chronic osteoarthritis knee pain. Data from two double-blind, randomized, placebo- and oxycodone CR-controlled phase 3 studies with a 3-week titration period and 12-week controlled dose adjustment maintenance period were pooled. Primary efficacy end-points were change from baseline in average pain intensity at week 12 (US end-point) and over the entire maintenance period (non-US end-point). A total of 2,010 patients were assessed. For both primary end-points, tapentadol PR was significantly more effective than oxycodone CR (LS mean difference of -0.41 [95% CI = -0.65, -0.16; p = 0.001] at week 12 and -0.35 [95% CI = -0.58, -0.12; p = 0.003] over 12 weeks of maintenance [last observation carried forward]). Significantly better outcomes than for oxycodone CR were also observed for patient global impression of change, both Short Form-36 component scores, and EuroQoL-5Dimensions health status index (all p tapentadol PR than for oxycodone CR. A higher proportion of oxycodone CR patients discontinued treatment (64% vs 42.2% for tapentadol PR); time to treatment discontinuation due to an adverse event was significantly shorter for oxycodone CR (p tapentadol PR provided superior pain relief and a more improved overall health status than oxycodone CR in a large patient population with moderate-to-severe chronic osteoarthritis pain. Compared to oxycodone CR, tapentadol PR showed a more favorable tolerability profile with better gastrointestinal tolerability.

    Melasma is a commonly acquired hyperpigmentation symmetrically distributed on the face, neck, and arms. The skin-lightening properties of Rumex occidentalis make it a therapeutic alternative to the reference standard treatment of hydroquinone (HQ). This study was conducted to evaluate the safety and efficacy of 3% R. occidentalis cream versus 4% HQ cream in the management of epidermal and mixed melasma. This was a randomized, double-blind, placebo-controlled trial. Forty-five subjects with epidermal and mixed melasma were recruited to compare 3% R. occidentalis cream, 4% HQ cream, and placebo cream applied twice daily for eight weeks. Changes in pigmentation were measured every two weeks using the Melasma Area Severity Index (MASI) and a mexameter. Adverse events were noted on every visit. Patient and investigator global evaluations were performed at the end of the study. Overall mean MASI and mexameter readings in the three groups decreased from baseline to week 8. The greatest decline in score from weeks 2 to 6 was achieved by the HQ group, followed by the R. occidentalis group. By week 8, the R. occidentalis group showed a greater mean ± standard deviation decline in MASI and mexameter readings from baseline (MASI: 0.60 ± 0.86; mexameter: 50.56 ± 25.63) than the HQ group (MASI: 0.55 ± 0.62; mexameter: 45.89 ± 47.83). The efficacy of R. occidentalis cream and HQ cream were assessed as similarly favorable by both study subjects and investigators. Rumex occidentalis 3% cream is a safe and effective skin-lightening agent for melasma and is comparable in efficacy with 4% HQ cream. © 2014 The International Society of Dermatology.

    Rotigotine-a non-ergot dopamine agonist-has two advantages; it can stimulate all dopamine receptors (D1-D5) like innate dopamine, and its transdermal administration provides continuous dopaminergic stimulation. The age of the patient impacts the effect and adverse events of anti-parkinsonian treatment. We conducted a post hoc analysis on three randomized, double-blind, placebo-controlled trials performed in Japan to clarify the difference of anti-parkinsonian treatment in elderly and non-elderly patients. Data from two combination therapy trials (with levodopa) in advanced stage Parkinson's disease patients and one monotherapy trial in early stage patients were pooled and grouped by age (non-elderly aged < 70, elderly aged 70 +). In each age group, efficacy of rotigotine was compared to placebo. In the combination therapy, total Unified Parkinson's Disease Rating Scale Part III scores and some subtotal scores, including those for tremor, akinesia and gait disturbance, significantly improved in both elderly and non-elderly patients. Regarding safety, the incidence of total adverse event tended to be lower in elderly patients than non-elderly patients, although it was not significant. No difference was observed in maintenance dosage of rotigotine between the two groups. In conclusion, the improvement in motor symptoms and frequency of adverse events were shown to be similar in elderly and non-elderly patients with rotigotine-levodopa combination therapy. Further, there was no major difference in maintenance dosage of rotigotine between the age groups. These results suggest good tolerability of rotigotine among elderly patients.

    Bacterial vaginosis (BV), a prevalent infection in women of reproductive age, is associated with increased risk of upper genital tract and sexually transmitted infections, and complications in pregnancy. Currently approved treatments include metronidazole, which requires once or twice daily intravaginal administration for 5 days or twice daily oral administration for 7 days. This phase 3 study determined the safety and efficacy of single-dose metronidazole vaginal gel (MVG) 1.3%. In this double-blind, vehicle-controlled study, 651 women with clinical diagnosis of BV were randomized 1:1 to receive MVG 1.3% or vehicle vaginal gel. Primary efficacy measure was clinical cure (normal discharge, negative "whiff test," and <20% clue cells) at day 21. Secondary measures included therapeutic cure (both clinical and bacteriological; day 21) and bacteriologic cure (Nugent score <4), clinical cure, and time to resolution of symptoms (day 7). A total of 487 participants were included in the primary analysis. Clinical and therapeutic cure rates (day 21) were higher in participants treated with MVG 1.3% compared with vehicle gel (37.2% vs. 26.6% [P = 0.010] and 16.8% vs. 7.2% [P = 0.001], respectively). Clinical and bacteriologic cure rates (day 7) were also higher in the MVG 1.3% group (46.0% vs. 20.0% [P < 0.001] and 32.7% vs. 6.3% [P < 0.001], respectively). The median time to resolution of symptoms was shorter in the MVG 1.3% (day 6) than vehicle group (not reached). No serious adverse events were reported, and incidence was similar across treatment groups. Single-dose MVG 1.3% was safe and superior to vehicle gel in producing cure among women with BV.

    This study assessed the efficacy and safety of vortioxetine in adults with major depressive disorder. In this double-blind, placebo-controlled study, 600 patients with major depressive disorder were randomly assigned (1:1:1:1) to receive vortioxetine 5, 10, or 20 mg, or placebo once daily for 8 weeks. The primary end-point was change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score at week 8, evaluated by the last-observation-carried-forward method. Secondary end-points included response (≥ 50% decrease in the MADRS total score from baseline) and remission (MADRS total score ≤ 10), Clinical Global Impression Scale-Improvement, and change from baseline in Sheehan Disability Scale. Adverse events were summarized. Vortioxetine failed to show significant differences from placebo in the primary end-point. Nominally significant improvements over placebo were observed for vortioxetine doses of 10 and 20 mg when the primary end-point was evaluated using the mixed model for repeated measures as the secondary analysis, and 10 mg in secondary measures of response and patient functioning. Vortioxetine was well tolerated. Nausea, constipation, dry mouth, dizziness, and insomnia each occurred at a >twofold higher rate than placebo. Discontinuation symptom scores were comparable between all groups after 1 and 2 weeks following withdrawal of the study drug. While vortioxetine failed to meet significance versus placebo in the primary efficacy analysis, there was evidence of efficacy for the 10- and 20-mg doses in secondary analyses. Vortioxetine was safe and well tolerated. Additional studies appear warranted. © 2017 The Authors.

    Electroencephalography (EEG)-neurofeedback has been shown to offer therapeutic benefits to patients with attention-deficit/hyperactivity disorder (ADHD) in several, mostly uncontrolled studies. This pilot study is designed to test the feasibility and safety of using a double-blind placebo feedback-controlled design and to explore the initial efficacy of individualized EEG-neurofeedback training in children with ADHD. Fourteen children (8-15 years) with ADHD defined according to the DSM-IV-TR criteria were randomly allocated to 30 sessions of EEG-neurofeedback (n = 8) or placebo feedback (n = 6). Safety measures (adverse events and sleep problems), ADHD symptoms and global improvement were monitored. With respect to feasibility, all children completed the study and attended all study visits and training sessions. No significant adverse effects or sleep problems were reported. Regarding the expectancy, 75% of children and their parent(s) in the active neurofeedback group and 50% of children and their parent(s) in the placebo feedback group thought they received placebo feedback training. Analyses revealed significant improvements of ADHD symptoms over time, but changes were similar for both groups. This pilot study shows that it is feasible to conduct a rigorous placebo-controlled trial to investigate the efficacy of neurofeedback training in children with ADHD. However, a double-blind design may not be feasible since using automatic adjusted reward thresholds may not work as effective as manually adjusted reward thresholds. Additionally, implementation of active learning strategies may be an important factor for the efficacy of EEG-neurofeedback training. Based on the results of this pilot study, changes are made in the design of the ongoing study.

    Cellulite of the upper lateral and posterior thighs and lower buttocks represents a common, physiological and unwanted condition whose etiologies and effective management are subjects of continued debate. The purpose of this controlled, double-blinded study is to evaluate the efficacy and safety of a novel phosphatidylcholine-based, cosmeceutical anti-cellulite gel combined with a light-emitting diode (LED) array at the wavelengths of red (660 nm) and near-infrared (950 nm), designed to counter the possible mechanisms that purportedly accentuate the presence of thigh cellulite. Nine healthy female volunteers with Grade II-III thigh cellulite were randomly treated twice daily with an active gel on one thigh and a placebo gel on the control thigh for 3 months. Twice weekly, each thigh was exposed for a 15-minute treatment with LED light for a total of 24 treatments. At 0, 6, and 12 weeks of the study the following clinical determinants were obtained: standardized digital photography, height and weight measurements, standardized thigh circumference tape measurements, pinch testing, body mass index (kg/m2), body fat analysis (Futrex-5500/XL near-infrared analyzer), and digital high-resolution ultrasound imaging of the dermal-adiposal border. In selected patients, full-thickness biopsies of the placebo and active-treated sites were obtained. At 18 months, repeat standardized digital photography, height and weight measurements, and body mass index measurements were obtained. At the end of 3 months, eight of nine thighs treated with the phosphatidylcholine-based, anti-cellulite gel and LED treatments were downgraded to a lower cellulite grade by clinical examination, digital photography, and pinch test assessment. Digital ultrasound at the dermal-adiposal interface demonstrated not only a statistically significant reduction of immediate hypodermal depth, but also less echo-like intrusions into the dermal layer. Three of six biopsies from thighs treated for 3 months with

    This randomized double-blind multicenter trial (NCT01927861) evaluated the growth-promoting effect and safety of Norditropin® (NN220; somatropin) in Japanese children with short stature due to Noonan syndrome. Prepubertal children aged 3-<11 years (boys) or 3-<10 years (girls) with Noonan syndrome were randomized to receive GH 0.033 mg/kg/day (n = 25, mean age 6.57 years, 11 females) or 0.066 mg/kg/day (n = 26, mean age 6.06 years, eight females) for 104 weeks. Change in height standard deviation score (HSDS) from baseline was analyzed based on an ANCOVA model. Baseline HSDS was -3.24. Estimated change in HSDS [95% CI] after 104 weeks' treatment was 0.84 [0.66, 1.02] and 1.47 [1.29, 1.64] for the lower and higher doses, respectively; estimated mean difference 0.63 [0.38, 0.88], p < 0.0001. Rates and patterns of adverse events (AEs) were similar between groups. Most were mild and reported as unlikely to be related to Norditropin®. There were no withdrawals due to AEs. Insulin-like growth factor-I SDS increased from -1.71 to -0.64 (0.033 mg/kg/day) and to 0.63 (0.066 mg/kg/day). HbA1c increased slightly (0.033 mg/kg/day: +0.14%; 0.066 mg/kg/day: +0.13%); glucose profiles were almost unchanged; insulin profiles increased in both groups in the oral glucose tolerance test. There were no clinically significant abnormal electrocardiogram or echocardiography findings. We conclude that Norditropin® at doses of 0.033 mg/kg/day or 0.066 mg/kg/day for 104 weeks increases height in Japanese children with short stature due to Noonan syndrome, with a favorable safety profile. The effect was greater with 0.066 mg/kg/day compared with 0.033 mg/kg/day.

    Background The FMP2.1/AS02A candidate malaria vaccine was tested in a Phase 2 study in Mali. Based on results from the first eight months of follow-up, the vaccine appeared well-tolerated and immunogenic. It had no significant efficacy based on the primary endpoint, clinical malaria, but marginal efficacy against clinical malaria in secondary analyses, and high allele-specific efficacy. Extended follow-up was conducted to evaluate extended safety, immunogenicity and efficacy. Methods A randomized, double-blinded trial of safety, immunogenicity and efficacy of the candidate Plasmodium falciparum apical membrane antigen 1 (AMA1) vaccine FMP2.1/AS02A was conducted in Bandiagara, Mali. Children aged 1–6 years were randomized in a 1∶1 ratio to receive FMP2.1/AS02A or control rabies vaccine on days 0, 30 and 60. Using active and passive surveillance, clinical malaria and adverse events as well as antibodies against P. falciparum AMA1 were monitored for 24 months after the first vaccination, spanning two malaria seasons. Findings 400 children were enrolled. Serious adverse events occurred in nine participants in the FMP2.1/AS02A group and three in the control group; none was considered related to study vaccination. After two years, anti-AMA1 immune responses remained significantly higher in the FMP2.1/AS02A group than in the control group. For the entire 24-month follow-up period, vaccine efficacy was 7.6% (p = 0.51) against first clinical malaria episodes and 9.9% (p = 0.19) against all malaria episodes. For the final 16-month follow-up period, vaccine efficacy was 0.9% (p = 0.98) against all malaria episodes. Allele-specific efficacy seen in the first malaria season did not extend into the second season of follow-up. Interpretation Allele-specific vaccine efficacy was not sustained in the second malaria season, despite continued high levels of anti-AMA1 antibodies. This study presents an opportunity to evaluate correlates of partial protection against

    The efficacy and safety of Chinese herbs for symptomatic treatment of bronchitis is not well established. We evaluated the efficacy and safety of a combination product of seven herbs (HL301) for the treatment of acute bronchitis (AB) and acute exacerbation of chronic bronchitis (AECB) using a randomized, double-blind, placebo-controlled, multicenter trial design. A total of 160 patients with AB or with AECB were randomized to receive placebo or one of three doses of HL301 (0.6 g/day, 1.2 g/day, or 1.8 g/day) for a total of 7 days. The primary study endpoint was the change in bronchitis severity score (BSS) from the baseline visit (visit 2) to the end of treatment visit (visit 3). Other efficacy variables were percentage BSS systemic sign efficacy after treatment and change in individual BSS parameters after treatment. Changes in BSS from visit 2 to visit 3 in the three treatment groups (4.63 ± 2.24, 4.08 ± 1.63, and 4.15 ± 1.74 in the HL301 0.6 g/day, 1.2 g/day, and 1.8 g/day groups, respectively) were higher than that of the placebo group (2.88 ± 2.57) in the per protocol set (PPS) (P < .05), and it was also valid in the full analysis set (FAS). The number of participants whose symptoms (measured by BSS) improved at least 30% after treatment was higher in all three treatment groups compared to the placebo group in both the FAS and the PPS (P < .05, for all). Three different doses of HL301 (0.6 g/day, 1.2 g/day, and 1.8 g/day) were effective in decreasing the BSS index compared to placebo. HL301 may be effective for symptomatic treatment of both AB and AECB. Essential components of HL301 have not been delineated in the study and patients with AB and AECB were indiscriminately enrolled in the present study. Respective evaluation of the efficacy of HL301 for AB and AECB will be necessary in the future.

    Context: Stress is a state of mental or emotional strain or tension, which can lead to underperformance and adverse clinical conditions. Adaptogens are herbs that help in combating stress. Ayurvedic classical texts, animal studies and clinical studies describe Ashwagandha as a safe and effective adaptogen. Aims: The aim of the study was to evaluate the safety and efficacy of a high-concentration full-spectrum extract of Ashwagandha roots in reducing stress and anxiety and in improving the general well-being of adults who were under stress. Settings and Design: Single center, prospective, double-blind, randomized, placebo-controlled trial. Materials and Methods: A total of 64 subjects with a history of chronic stress were enrolled into the study after performing relevant clinical examinations and laboratory tests. These included a measurement of serum cortisol, and assessing their scores on standard stress-assessment questionnaires. They were randomized to either the placebo control group or the study drug treatment group, and were asked to take one capsule twice a day for a period of 60 days. In the study drug treatment group, each capsule contained 300 mg of high-concentration full-spectrum extract from the root of the Ashwagandha plant. During the treatment period (on Day 15, Day 30 and Day 45), a follow-up telephone call was made to all subjects to check for treatment compliance and to note any adverse reactions. Final safety and efficacy assessments were done on Day 60. Statistical Analysis: t-test, Mann-Whitney test. Results: The treatment group that was given the high-concentration full-spectrum Ashwagandha root extract exhibited a significant reduction (PAshwagandha group, relative to the placebo group. The adverse effects were mild in nature and were comparable in both the groups. No serious adverse events were reported. Conclusion: The findings of this study suggest that a high-concentration full-spectrum Ashwagandha root extract safely and effectively

    AV7909 vaccine being developed for post-exposure prophylaxis of anthrax disease may require fewer vaccinations and reduced amount of antigen to achieve an accelerated immune response over BioThrax(®) (Anthrax Vaccine Adsorbed). A phase 2, randomized, double-blind, BioThrax vacccine-controlled study was conducted to evaluate the safety and immunogenicity of three intramuscular vaccination schedules and two dose levels of AV7909 in 168 healthy adults. Subjects were randomized at a 4:3:2:4:2 ratio to 5 groups: (1) AV7909 on Days 0/14; (2) AV7909 on Days 0/28; (3) AV7909 on Days 0/14/28; (4) half dose AV7909 on Days 0/14/28; and (5) BioThrax vaccine on Days 0/14/28. Vaccinations in all groups were well tolerated. The incidences of adverse events (AEs) were 79% for AV7909 subjects and 65% for BioThrax subjects; 92% of AV7909 subjects and 87% of BioThrax subjects having AEs reported Grade 1-2 AEs. No serious AEs were assessed as potentially vaccine-related, and no AEs of potential autoimmune etiology were reported. There was no discernible pattern indicative of a safety concern across groups in the incidence or severity of reactogenicity events. Groups 2-4 achieved success for the primary endpoint, demonstrated by a lower 95% confidence limit of the percentage of subjects with protective toxin neutralizing antibody NF50 values (≥0.56) to be ≥40% at Day 63. Group 1 marginally missed the criterion (lower bound 95% confidence limit of 39.5%). Immune responses were above this threshold for Groups 1, 3 and 4 at Day 28 and all groups at Day 42. Further study of an AV7909 two-dose schedule given 2 weeks apart is warranted in light of the favorable tolerability profile and immunogenicity response relative to three doses of BioThrax vaccine, as well as preliminary data from nonclinical studies indicating similar immune responses correlate with higher survival for AV7909 than BioThrax vaccine.

    Topical fixed-combination therapy containing 1% clindamycin as 1.2% clindamycin phosphate (CLNP) and 3% benzoyl peroxide (BPO) is an effective treatment for acne vulgaris (acne). To demonstrate that the combination of 1.2% CLNP with lower strength BPO (CLNP 1.2%-BPO 3%) in a gel formulation is superior to each individual ingredient, CLNP 1.2% and BPO 3%, and vehicle gel. A total of 1,319 patients with acne, aged 12 years or older, were enrolled and randomized (1:1:1:1) to receive CLNP 1.2%-BPO 3%, CLNP 1.2% gel, BPO 3% gel, or vehicle gel once-daily in a 12-week, multicenter, double-blind, parallel-group, vehicle-controlled study. Subjects were evaluated at baseline, weeks 2, 4, 8, and 12 or early termination. Assessment of efficacy was evaluated using a six-point Investigator's Static Global Assessment (ISGA) and Subject's Global Assessment (SGA) of acne severity and lesion counts (inflammatory, non-inflammatory, and total). Safety assessments included skin tolerability and adverse events (AEs). A greater proportion of subjects who used CLNP 1.2%-BPO 3% gel (39%) had a two grade improvement in ISGA from baseline to week 12 compared with CLNP 1.2% (25%; PBPO 3% (30%; P=0.016), and vehicle (18%; PBPO 3% was superior to CLNP 1.2% and vehicle alone in the absolute reduction from baseline to week 12 in all three lesion types (PBPO 3% was superior to BPO 3% alone in the absolute reduction from baseline to week 12 in inflammatory (P=0.015) and total (P=0.032) lesion counts. The incidence of product-related AEs was low and similar in all study groups (1% with CLNP 1.2%-BPO 3%, 2% with CLNP 1.2%, 2% with BPO 3%, and 2% with vehicle). Local tolerability assessments showed similar minimal changes from baseline to week 12 in all study groups. CLNP 1.2%-BPO 3% gel provides superior efficacy to improve ISGA score and reduce inflammatory and total lesion counts compared with the individual active ingredients (CLNP 1.2% and BPO 3%) and vehicle, while maintaining a highly

    To determine if Lactobacillus plantarum DSM9843 (LP299V) reduces the frequency of antibiotic-associated loose/watery stools and gastrointestinal symptoms, and can be administered safely to children who are prescribed antibiotics. We performed a prospective, double-blind, randomized, placebo-controlled, multicenter, parallel-group study in children receiving outpatient antibiotic therapy in primary healthcare settings. The children were given LP299V/placebo during the antibiotic therapy and for 1 week after the end of treatment. The primary outcome measure was the incidence of at least 1 loose/watery stool (type 6 or 7 according to the Bristol Stool Form Scale). Gastrointestinal symptoms (abdominal pain, abdominal distention, vomiting, and flatulence) were followed up until 1 week after the last intake of the study product. A total of 438 children (male: 235, female: 203) aged 1-11 years (mean ± SD: 5.2 ± 2.7) were randomized to receive LP299V (N = 218) or placebo (N = 220). The incidence of loose/watery stools in the 2 study groups (LP299V and placebo) was similar, 39% vs 44.5% respectively (P = .26) as was the mean number of loose/watery stools (3.9 ± 3.5 vs 4.7 ± 6.3; P = .9). Antibiotic-associated diarrhea (defined as ≥3 loose/watery stools/24 hours starting from 2 hours after initiation of antibiotic treatment until the end of the study) occurred in 2.8% of the subjects receiving LP299V compared with 4.1% in the placebo arm (P = .4). The number of children with abdominal symptoms did not differ between the groups. No beneficial effect of LP299V compared with placebo was observed for the incidence of loose/watery stools, mean number of loose/watery stools, or the incidence of abdominal symptoms. LP299V had a satisfactory safety profile. ClinicalTrials.gov: NCT01940913. Copyright © 2017 Elsevier Inc. All rights reserved.

    Fumaric acid esters (FAEs) are recommended in international guidelines for induction and long-term treatment of adults with moderate-to-severe chronic plaque psoriasis. The fixed combination Fumaderm ® is approved in Germany, with dimethyl fumarate (DMF) being the main active ingredient. To assess the efficacy and safety of a new formulation of DMF (LAS41008), compared with placebo and Fumaderm ® , in adults with moderate-to-severe chronic plaque psoriasis. In this phase III, double-blind, placebo-controlled, noninferiority trial (BRIDGE, NCT01726933, EudraCT 2012-000055-13), patients were randomized to receive LAS41008, Fumaderm ® or placebo (2 : 2 : 1) for 16 weeks, uptitrating to a maximum daily DMF dose of 720 mg, depending upon individual response. The coprimary end points were the percentage of patients achieving ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) and the percentage achieving a score of 'clear' or 'almost clear' in the Physician's Global Assessment (PGA) at week 16. In total, 671 patients were randomized and included in the full analysis set (n = 267, LAS41008; n = 273, Fumaderm ® ; n = 131, placebo). At week 16, 37·5% of patients treated with LAS41008 achieved PASI 75, compared with 15·3% receiving placebo (superiority for LAS41008 vs. placebo: P < 0·001) and 40·3% receiving Fumaderm ® (noninferiority for LAS41008 vs. Fumaderm ® : P < 0·001). Overall, 33% of patients treated with LAS41008 were 'clear' or 'almost clear' in the PGA at week 16, compared with 13·0% receiving placebo (P < 0·0001; LAS41008 superiority vs. placebo) and 37·4% receiving Fumaderm ® . Most treatment-related adverse events were classed as 'mild' in severity. LAS41008 (DMF) is effective in the treatment of adults with moderate-to-severe chronic plaque psoriasis. © 2016 The Authors.

    Knee osteoarthritis (OA) conservative treatment aims to delay cartilage degeneration; chondroprotective agents are a valid approach in this sense. A commercially available dietary supplement, CartiJoint Forte, containing glucosamine hydrochloride (GH), chondroitin sulfate (CS) and Bio-Curcumin BCM-95®, was used in this trial. The aim of this study was to assess efficacy and safety of CartiJoint Forte combined with physical therapy in treating subjects with knee OA. A multicenter, prospective, randomized, double blind, placebo-controlled clinical trial. Outpatients referred to the Rehabilitation Departments of two University Hospitals. Fifty-three patients were randomly assigned to an experimental group (N=26) or a control group (N.=27). Experimental subjects received two tablets of CartiJoint Forte each day for 8 weeks, while those in the control group were provided with a placebo. Three subjects dropped out during the course of the study. The two groups both received 20 sessions of physical therapy during the course of the trial. Primary outcome was pain intensity, measured both at motion and at rest, using the Visual Analogue Scale (VAS). A secondary outcome was an assessment of knee function by Western Ontario and McMaster Universities Arthritis Index and Lequesne Index, knee ROM, and two inflammation markers (C-reactive protein and erythrocyte sedimentation rate). Each assessment was carried out at baseline (T0), at 8 weeks (T1) and at 12 weeks (T2). VAS at rest was found to be reduced between T0 and T1, as well as between T0 and T2 (F=13.712; P=0.0001), with no differences between groups (F=1.724; P=0.191). VAS at motion revealed a significant "group × time-check" interaction (F=2.491; P=0.032), with increasing effect of time on VAS reduction (F=17.748; P=0.0001). This was most pronounced in the experimental group at 8 weeks (F=3.437; P=0.045). The Lequesne Index showed reductions at T1 and T2 compared to T0 (F=9.535; P=0.0001), along with group effect

    Children with type 1 diabetes (T1D) and elevated LDL-C have an increased risk for cardiovascular disease, a process that can begin in childhood. To assess the safety and efficacy of atorvastatin improving lipid profiles in children with T1D and elevated LDL-C. Sixty children (31M/29F) with T1D, mean age: 15 ± 0.3 yr, mean diabetes duration: 6.8 ± 0.5 yr, HbA(1c) : 8.8 ± 0.2%, with mean LDL-C 124 ± 4.0mg/dl were recruited. After a 3-month run-in period, subjects were randomized double-blindly to atorvastatin or placebo for 6 months. Lipoprotein subfractions were measured by ion mobility and glucose control by HbA1C; continuous glucose monitors were worn quarterly. After a run-in period, 42 subjects were randomized. There were decreases in total cholesterol (-21%), LDL-C (-32%), non-HDL-C (-31%) and apoB (-26%) in the atorvastatin group versus placebo (p < 0.001). Lipoprotein subparticles (LDL-large 1 and 2A, IDL-large and small, VLDL- medium and small) decreased with statins (p < 0.03 all). Insulin sensitivity scores remained constant in both groups and correlated inversely with apoB (r = -0.312 p = 0.039) and small LDL 3A (r = -0.404 p = 0.007). One subject had asymptomatic elevation of creatinine kinase which normalized after atorvastatin discontinuation. Atorvastatin lowered LDL-C, apoB, and atherogenic lipoprotein subparticles in children with T1D and elevated LDL-C without worsening insulin resistance. The drug was well tolerated and safe. Long-term studies would provide better insight on the impact of these interventions in the development of cardiovascular disease in children with diabetes. © 2014 John Wiley & Sons A/S.

    This randomized, double-blind, placebo-controlled phase III study was conducted to assess the efficacy and safety of oral calcitonin (SMC021) for the treatment of postmenopausal osteoporosis. A total of 4665 postmenopausal women with osteoporosis were randomized 1:1 to receive calcium and vitamin D plus either SMC021 tablets (0.8mg/d) or placebo for 36months. The primary endpoint was the proportion of patients with a new vertebral fracture. The two groups were well balanced at baseline with regards to demographic and clinical data. No effect of SMC021 on preventing new vertebral fractures was observed, nor was any effect seen on new hip or non-vertebral fractures. Women receiving SMC021 had a mean 1.02% (±0.12%) increase in lumbar spine bone mineral density (BMD) compared with a mean 0.18% (±0.12%) increase in the placebo group by the end of the study (p<0.0001). Similarly, small increases in BMD were observed at the femoral neck and hip in both groups. Levels of the biomarkers of bone turnover, urinary CTX-I and CTX-II, were 15% lower in the SMC021 group than in the placebo arm at 12 and 24months, but not at 36months. No change in quality of life between groups, assessed by the Qualeffo-14 questionnaire, was observed in either group between baseline and month 36. Pharmacokinetics analysis confirmed exposure to SMC021, but the drug levels were markedly lower than expected. Approximately 92% of subjects in each treatment group experienced an adverse event (AE), the majority of which were mild or moderate in intensity. AEs associated with SMC021 were primarily of gastrointestinal origin and included nausea, vomiting and abdominal pain, as well as hot flushes which were the reason for the slightly higher drop-out rate in the active treatment arm compared to placebo. The number of severe AEs was low in both groups. Thirty-five deaths were reported but none were considered treatment-related. Due to the lack of efficacy in preventing fractures, the development of the

    Tonsillectomy is one of the most common pediatric surgical procedures performed in the United States. The postoperative period can be particularly painful, and there is currently no consensus on an optimal analgesic regimen. The objective of this study was to evaluate efficacy and safety of the single drug tramadol versus codeine/acetaminophen post-tonsillectomy. Prospective, double-blinded, randomized controlled trial. Large, Midwestern US pediatric hospital. Eighty-four children aged 4-15 years who underwent a tonsillectomy (with or without adenoidectomy) procedure were randomized and 74 were included in the analysis. Group 1 received liquid codeine/acetaminophen for 10 days post-tonsillectomy (5 days scheduled, followed by 5 days as-needed). Group 2 received liquid tramadol for 10 days post-tonsillectomy (5 days scheduled, followed by 5 days as-needed). Efficacy and side effects were evaluated using a 10-day take-home diary that was completed by parents. Children in both study arms reported adequate post-tonsillectomy pain management without significant differences between groups in pain scores. Oversedation was significantly higher on the day of surgery in the codeine/acetaminophen group, and itching was experienced by significantly more children in the tramadol group during the postoperative period. As part of multimodal analgesia, scheduled plus as-needed tramadol may be considered for children in the postoperative setting due to its analgesic properties, low potential for side effects, and good safety profile.

    This study compares the immunogenicity and safety of a single dose of a new meningococcal A conjugate vaccine (PsA-TT, MenAfriVac™, Serum Institute of India Ltd., Pune) against the meningococcal group A component of a licensed quadrivalent meningococcal polysaccharide vaccine (PsACWY, Mencevax ACWY(®), GSK, Belgium) 28 days after vaccination in Indian children. This double-blind, randomized, controlled study included 340 Indian children aged 2-10 years enrolled from August to October 2007; 169 children received a dose of PsA-TT while 171 children received a dose of PsACWY. Intention-to-treat analysis showed that 95.2% of children in PsA-TT group had a ≥4-fold response in serum bactericidal titers (rSBA) 28 days post vaccination as compared to 78.2% in the PsACWY group. A significantly higher rSBA GMT (11,209, 95%CI 9708-12,942) was noted in the PsA-TT group when compared to PsACWY group (2838, 95%CI 2368-3401). Almost all children in both vaccine groups had a ≥4-fold response in group A-specific IgG concentration but the IgG GMC was significantly greater in the PsA-TT group (89.1 μg/ml, 95%CI 75.5-105.0) when compared to the PsACWY group (15.3 μg/ml, 95%CI 12.3-19.2). Local and systemic reactions during the 4 days after immunization were similar for both vaccine groups except for tenderness (30.2% in PsA-TT group vs 12.3% in PsACWY group). None of the adverse events or serious adverse events was related to the study vaccines. We conclude that MenAfriVac™ is well tolerated and significantly more immunogenic when compared to a licensed polysaccharide vaccine, in 2-to-10-year-old Indian children.

    This study evaluated the efficacy and tolerability of modafinil at a range of doses, versus placebo, in alleviating symptoms of ADHD in adults. Adult patients with ADHD were randomized in 1:1:1:1:1 fashion to double-blind treatment with modafinil 255, 340, 425, or 510 mg daily or placebo for 9 weeks. The primary efficacy outcome was the change from baseline at final visit in the Adult ADHD Investigator Symptom Rating Scale (AISRS) total score. A total of 338 patients were enrolled, of whom 330 received at least 1 dose of study medication (modafinil or placebo). No statistically significant difference in the AISRS total score was observed at final visit between any modafinil group and placebo; however, some observations among patients who completed the trial may warrant further investigation. Modafinil was reasonably tolerated but did not demonstrate a benefit on ADHD symptoms in adults.

    Anidulafungin is a novel antifungal agent of the echinocandin class. This randomized, double-blind, double-dummy study compared the efficacy and safety of intravenous anidulafungin to that of oral fluconazole in 601 patients with endoscopically and microbiologically documented esophageal candidiasis. Patients received intravenous anidulafungin (100 mg on day 1, followed by 50 mg per day) or oral fluconazole (200 mg on day 1, followed by 100 mg per day) for 7 days beyond resolution of symptoms (range, 14-21 days). At the end of therapy, the rate of endoscopic success for anidulafungin (242 [97.2%] of 249 treated patients) was found to be statistically noninferior to that for fluconazole (252 [98.8%] of 255 treated patients; treatment difference, -1.6%; 95% confidence interval, -4.1 to 0.8). The safety profile of anidulafungin was similar to that of fluconazole; treatment-related adverse events occurred in 9.3% and 12.0% of patients, respectively. Laboratory parameters were similar between treatment arms. Anidulafungin is as safe and effective as oral fluconazole for the treatment of esophageal candidiasis, when assessed at the completion of therapy.

    Rotigotine, a non-ergot dopamine receptor agonist, offers potential for continuous dopaminergic stimulation that could avoid the fluctuations observed with traditional treatments. We conducted a randomized, double-blind, placebo-controlled trial in Japanese patients with advanced Parkinson's disease (PD) to investigate the efficacy and safety of rotigotine. Inclusion criteria included the presence of motor complications, such as wearing off, on-off, delayed-on/no-on, any circumstances that could interfere with levodopa dose escalation because of side effects, or declining levodopa efficacy. The enrolled patients received once-daily applications of rotigotine transdermal patches or matched placebo patches. A total of 174 patients were randomly assigned to rotigotine (87 patients) or placebo (87 patients). The full analysis set included 172 patients (86 for the rotigotine group and 86 for the placebo group). The maximum maintenance dose of rotigotine was set at 16 mg/24 h. The changes in unified PD rating scale Part III scores from baseline to the end of the trial were -10.1 ± 9.0 (mean ± standard deviation) in the rotigotine group and -4.4 ± 7.4 in the placebo group (p patients in each group. Rotigotine at doses of up to 16 mg/24 h is efficacious and safe in Japanese patients with advanced PD.

    Albendazole (ABZ) is a benzimidazole carbamate compound currently in use for human medical practice against enterobiasis and soil-transmitted helminthiasis (STH); However, its spectrum of activity is broad and goes beyond these infections. This study compares the efficacy and safety of ABZ versus metronidazole (MTZ) in human giardiasis. A randomized, double-blind, clinical trial was carried out at the Centre of Hygiene, Epidemiology and Microbiology in Matanzas City, Cuba. Adult patients with confirmed symptomatic G. duodenalis mono-infection were randomly assigned to receive either ABZ [400 mg daily (n = 75)] or MTZ [250 mg t.i.d. (n = 75)], both for 5 days. Follow-up fecal samples were obtained at 3, 5, 7 days after treatment end. The efficacy was similar for both treatment groups: ABZ (82.6%) and MTZ (85.3%); p > 0.05. Side-effects including bitter taste, headache, vomiting and dizziness were significantly higher in the MTZ group. Abdominal pain was significantly higher in ABZ group. ABZ was found as effective as MTZ in the treatment of G. duodenalis infections in adult patients from Cuba and could be a useful drug in areas where co-infection with STH infections is common.

    The main objective of this study was to evaluate the efficacy and safety of Lactobacillus rhamnosus in children aged 4-48 months with atopic dermatitis. The design of this study was a two-center, double-blind, randomized, and placebo-controlled study with two parallel groups to evaluate the efficacy and safety profile of L. rhamnosus in children aged 4-48 months with atopic dermatitis diagnosed using Hanifin and Rajka criteria and with a Scoring of Atopic Dermatitis (SCORAD) ≥ 15 at enrollment. The duration of this study was 8 weeks with a total of five visits. The enrolled patients were allocated into either a treatment group (one ComProbi capsule containing L. rhamnosus a day) or a control group (one capsule of placebo a day) at a ratio of 1:1. The primary endpoint was to compare the mean change from baseline in SCORAD after 8 weeks of treatment. The other secondary end points were to compare the following: the mean changes from baseline in SCORAD at postbaseline visits, the frequency and total amount of the use of corticosteroids during the 8-week treatment, the frequency of atopic dermatitis and the symptom-free duration, the mean changes from baseline in Infant Dermatitis Quality of Life Questionnaire at Week 4 and Week 8, and the mean changes from baseline in the Dermatitis Family Impact Questionnaire at Week 4 and Week 8. The mean changes in SCORAD from baseline at Week 8 was -21.69 ± 16.56 in the L. rhamnosus group and -12.35 ± 12.82 in the placebo group for the intent-to-treat population (p = 0.014). For the per-protocol population, the mean change of SCORAD from baseline was -23.20 ± 15.24 in the L. rhamnosus group and -12.35 ± 12.82 in the placebo group (p = 0.003). Significant differences were demonstrated between groups at Week 8 in intensity in the intent-to-treat population and per-protocol population. Throughout the period, the amount of topical corticosteroids used showed no difference between groups. No significant

    To determine whether the tumor necrosis factor α inhibitor etanercept is well tolerated and obtain preliminary data on its safety in Alzheimer disease dementia. In a double-blind study, patients with mild to moderate Alzheimer disease dementia were randomized (1:1) to subcutaneous etanercept (50 mg) once weekly or identical placebo over a 24-week period. Tolerability and safety of this medication was recorded including secondary outcomes of cognition, global function, behavior, and systemic cytokine levels at baseline, 12 weeks, 24 weeks, and following a 4-week washout period. This trial is registered with EudraCT (2009-013400-31) and ClinicalTrials.gov (NCT01068353). Forty-one participants (mean age 72.4 years; 61% men) were randomized to etanercept (n = 20) or placebo (n = 21). Etanercept was well tolerated; 90% of participants (18/20) completed the study compared with 71% (15/21) in the placebo group. Although infections were more common in the etanercept group, there were no serious adverse events or new safety concerns. While there were some interesting trends that favored etanercept, there were no statistically significant changes in cognition, behavior, or global function. This study showed that subcutaneous etanercept (50 mg/wk) was well tolerated in this small group of patients with Alzheimer disease dementia, but a larger more heterogeneous group needs to be tested before recommending its use for broader groups of patients. This study shows Class I evidence that weekly subcutaneous etanercept is well tolerated in Alzheimer disease dementia. © 2015 American Academy of Neurology.

    Virtually no clinical trials for smoking cessation have been undertaken in bipolar disorder. Varenicline has shown efficacy for smoking cessation, but warnings about neuropsychiatric adverse events have been issued. We assessed the efficacy and safety of varenicline in euthymic bipolar subjects motivated to quit smoking. Clinically stable adult patients with DSM-IV bipolar disorder (n = 60) who smoked ≥ 10 cigarettes per day were randomized to a 3-month, double-blind, placebo-controlled varenicline trial and a 3-month follow-up. Study enrollment was completed from February 2010 through March 2013. Varenicline was dosed using standard titration, and smoking cessation counseling was provided to all patients. The primary outcome was defined as a 7-day point prevalence of self-reported no smoking verified by expired carbon monoxide level initiating smoking cessation in bipolar patients, but medication trials of longer duration are warranted for maintaining abstinence. Vigilance for neuropsychiatric adverse events is prudent when initiating varenicline for smoking cessation in this patient population.

    Full Text Available Metformin plays an important role in diabetes treatment. Studies have shown that the combined use of oral hypoglycemic medications is more effective than metformin monotherapy. In this double-blind, randomized, placebo-controlled, multicenter trial, we evaluated whether Jinlida, a Chinese herbal medicine, enhances the glycemic control of metformin in type 2 diabetes patients whose HbA1c was ineffectively controlled with metformin alone.A total of 186 diabetes patients were enrolled in this double-Blind, randomized, placebo-controlled, multicenter trial. Subjects were randomly allocated to receive either Jinlida (9 g or the placebo TID for 12 consecutive weeks. All subjects in both groups also continuously received their metformin without any dose change. During this 12-week period, the HbA1c, FPG, 2 h PG, body weight, BMI were assessed. HOMA insulin resistance (HOMA-IR and β-cell function (HOMA-β were also evaluated.At week 12, compared to the HbA1c level from week 0, the level of the Jinlida group was reduced by 0.92 ± 1.09% and that of the placebo group was reduced by 0.53 ± 0.94%. The 95% CI was 0.69-1.14 for the Jinlida group vs. 0.34-0.72 for the placebo group. There was a very significant HbA1c reduction between the two groups after 12 weeks (p < 0.01. Both FG and 2 h PG levels of the Jinlida group and placebo group were reduced from week 0. There were a very significant FG and 2 h PG level reductions between the two groups after 12 weeks (both p < 0.01. The Jinlida group also showed improved β-cell function with a HOMA-β increase (p < 0.05. No statistical significance was observed in the body weight and BMI changes. No serious adverse events were reported.Jinlida significantly enhanced the hypoglycemic action of metformin when the drug was used alone. This Chinese herbal medicine may have a clinical value as an add-on medication to metformin monotherapy.Chinese Clinical Trial Register ChiCTR-TRC-13003159.

    The ability to recognize and diagnose attention-deficit/hyperactivity disorder (ADHD) has increased in recent years. The persistence of ADHD symptoms puts adolescents with ADHD at risk for long-term adverse psychosocial outcomes. The primary goal of this study was to assess the efficacy and safety of mixed amphetamine salts extended release (MAS XR) in the management of adolescents with ADHD. This was a 4-week, randomized, multicenter, double-blind, placebo-controlled, parallel-group, forced-dose-titration study. Adolescents aged 13 to 17 years with ADHD were randomized to 1 of 4 active treatments (MAS XR 10, 20, 30 or 40 mg/d) or to placebo. All doses were given in the morning. This study used a forced-dose-titration design in which patients randomized to the 10-mg/d group received 1 dose of 10 mg/d for 4 weeks. Patients randomized to the 20-mg/d group received 1 dose of 10 mg/d for the first week and 1 dose of 20 mg/d for the remaining weeks; patients randomized to the 30-mg/d group received 1 dose of 10 mg/d for the first week, 1 dose of 20 mg/d for the second week, and 1 dose of 30 mg/d for the remaining 2 weeks; and patients randomized to the 40-mg/d group received 1 dose of 10 mg/d for the first week, 1 dose of 20 mg/d for the second week, 1 dose of 30 mg/d for the third week, and 1 dose of 40 mg/d for the fourth week. The primary efficacy measure was change from baseline to end point in the ADHD Rating Scale-IV (ADHD-RS-IV) score. The secondary efficacy measure was the score on the Clinical Global Impressions-Improvement (CGI-I) scale for ADHD. ADHD-RS-IV total scores were analyzed post hoc in patients with low baseline ADHD-RS-IV severity (ie, patients with baseline ADHD-RS-IV total scores less than the median) and high baseline ADHD-RS-IV severity (ie, patients with baseline ADHD-RS-IV total scores greater than the median). Safety was assessed by recording adverse events, vital signs, and body weight at all study visits and 30 days after drug

    Alzheimer's disease (AD) is commonly accompanied by aggressive behavior. In the elderly, effective and safe antiaggressive treatment is lacking. Risks of antipsychotics in this population demand therapeutic alternatives. This randomized, double-blind, pilot trial examined the efficacy and safety of cyproterone in the treatment of agitated AD. The subjects were 27 elderly patients referred to the University Hospital of Guadalajara Psychogeriatric Clinic diagnosed with AD and associated aggressive behavior (mean Staff Observation Aggression Scale [SOAS] score >or=2). Each patient underwent a 15-day washout for psychotropics and then was randomly assigned to receive stable doses of either cyproterone (100 mg/day) or haloperidol (2 mg/day) for 90 days. The primary outcome measure was the SOAS score. This trial was conducted between October 27, 1993, and March 24, 1998. Of the 27 patients, 19 (70.4%) were women, and the mean age was 80.7 years. The trial was completed by 24 (88.9%) of the subjects (13 in the cyproterone group and 11 in the haloperidol group for 90 days). Three patients (11.1%) dropped out, all after adverse effects in the haloperidol group. Baseline aggression level in the sample was mild (mean SOAS score of 4.48 [SD = 2.04]). Efficacy analyses for all intent-to-treat patients showed that 9 (69.2%) in the cyproterone group achieved complete elimination of aggression at endpoint, in contrast to 2 patients (14.2%) in the haloperidol group (p = .012). Ten patients (71.4%) taking haloperidol had adverse events, compared with 4 (30.7%) taking cyproterone (p = .035). Cyproterone showed significantly better efficacy and safety than haloperidol in controlling mild aggression associated with AD. Additional research is needed to confirm if these results can be ratified in a larger study and generalized to patients whose aggression is more severe.

    This double-blinded, randomized, vehicle-controlled, multicenter, parallel-group, 12-week, phase 4 study was conducted in adults with mild to moderate acne vulgaris. Of 178 subjects randomized to be treated, 88 subjects (49%) were treated with tretinoin gel microsphere 0.04% and 90 subjects (51%) were treated with vehicle. Inflammatory lesion counts were statistically significantly reduced at 2 weeks in tretinoin-treated subjects (P = .0110), and reductions in total lesion counts also were noted. The reduction in total lesion counts reached statistical significance at week 4 (P = .0305); at week 12, mean total, inflammatory, and noninflammatory lesion counts were statistically significantly lower in the tretinoin treatment group versus vehicle group (P tretinoin compared with vehicle (P tretinoin treatment group compared with 20.9%, 19.2%, and 20.4%, respectively, for the vehicle group (all P tretinoin-treated subject. At week 12, there were no statistically significant differences between treatment groups for any measured tolerability parameter.

    Abrupt cessation of alcohol intake causes habituated drinkers to experience symptoms of alcohol withdrawal syndrome (AWS). To determine the effect of the gamma-aminobutyric acid (GABA)-B agonist baclofen on the course of acute symptomatic AWS. Prospective, randomized, double-blind, placebo-controlled clinical study. Two tertiary-care hospitals in Duluth, Minnesota. Inpatient adults admitted for any reason (including AWS) judged to be at high risk for AWS. Inpatients who developed symptoms of AWS received symptom-triggered benzodiazepine treatment using lorazepam by standard protocol, and were randomized to receive baclofen 10 mg or placebo, 3 times per day, orally. AWS severity was assessed using the Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar); lorazepam dose was monitored. Seventy-nine subjects were enrolled. The 44 subjects who developed symptoms of AWS were randomized to baclofen or placebo. Thirty-one subjects (18 baclofen, 13 placebo) completed 72 hours of assessments, either entirely as inpatients or with outpatient follow-up. The need for high doses of benzodiazepines (20 mg or more of lorazepam over 72 hours) to control AWS was less likely in the baclofen treatment group (1 of 18) than in the placebo-treated group (7 of 13) (P = 0.004). We found that the use of baclofen was associated with a significant reduction in the use of high doses of benzodiazepine (lorazepam) in the management of symptomatic AWS. The use of low-dose baclofen in the management of AWS deserves further study, as reduced dependence on high-dose benzodiazepines in AWS management could improve patient safety.

    Fragile X syndrome (FXS), the most common cause of inherited intellectual disability and autistic spectrum disorder, is typically caused by transcriptional silencing of the X-linked FMR1 gene. Work in animal models has described altered synaptic plasticity, a result of the up-regulation of metabotropic glutamate receptor 5 (mGluR5)-mediated signaling, as a putative downstream effect. Post hoc analysis of a randomized, placebo-controlled, crossover phase 2 trial suggested that the selective mGluR5 antagonist mavoglurant improved behavioral symptoms in FXS patients with completely methylated FMR1 genes. We present the results of two phase 2b, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies of mavoglurant in FXS, designed to confirm this result in adults (n = 175, aged 18 to 45 years) and adolescents (n = 139, aged 12 to 17 years). In both trials, participants were stratified by methylation status and randomized to receive mavoglurant (25, 50, or 100 mg twice daily) or placebo over 12 weeks. Neither of the studies achieved the primary efficacy end point of improvement on behavioral symptoms measured by the Aberrant Behavior Checklist-Community Edition using the FXS-specific algorithm (ABC-C(FX)) after 12 weeks of treatment with mavoglurant. The safety and tolerability profile of mavoglurant was as previously described, with few adverse events. Therefore, under the conditions of our study, we could not confirm the mGluR theory of FXS nor the ability of the methylation state of the FMR1 promoter to predict mavoglurant efficacy. Preclinical results suggest that future clinical trials might profitably explore initiating treatment in a younger population with longer treatment duration and longer placebo run-ins and identifying new markers to better assess behavioral and cognitive benefits.

    Although mesenchymal stromal cells (MSCs) possess immunomodulatory properties and exhibit promising efficacy against chronic graft-versus-host disease (cGVHD), little is known about the efficacy of MSCs in the prophylaxis of cGVHD after HLA-haploidentical hematopoietic stem-cell transplantation (HLA-haplo HSCT). In this multicenter, double-blind, randomized controlled trial, we investigated the incidence and severity of cGVHD among patients, and the changes in T, B, and natural killer (NK) cells after the repeated infusion of MSCs. The 2-year cumulative incidence of cGVHD in the MSCs group was 27.4% (95% CI, 16.2% to 38.6%), compared with 49.0% (95% CI, 36.5% to 61.5%) in the non-MSCs control group (P = .021). Seven patients in the non-MSCs control group had severe lung cGVHD, but no patients in the MSCs group developed typical lung cGVHD (P = .047). After the MSC infusions, increasing memory B lymphocytes and regulatory T cells, as well as the ratio of type 1 T helper to type 2 T helper cells, were observed, whereas the number of NK cells decreased. Our findings suggest that the repeated infusion of MSCs might inhibit cGVHD symptoms in patients after HLA-haplo HSCT, accompanied by changes in the numbers and subtypes of T, B, and NK cells, leading to the acquisition of immune tolerance. © 2016 by American Society of Clinical Oncology.

    Antithrombin levels are often reduced in preeclampsia and infusion of antithrombin concentrates has been reported to prolong gestation in severe preeclampsia. We aimed to evaluate efficacy and safety of high-dose antithrombin (ATIII) supplementation in patients with single pregnancies and preeclampsia occurring before 30 weeks of gestation. In November 2004 a double-blind, placebo-controlled trial (code KB033) was started in 13 Italian centers. The planned sample size was of 240 patients (intention-to-treat, ITT population) to detect a 30% relative risk reduction of the primary endpoint, composite perinatal morbidity. Eligible patients were randomized to high dose AT (3000 IU/daily, ATIII Kedrion S.p.A., Italy), or placebo (1% glycine) for 7 days or less until delivery, whichever came first. The per-protocol (PP) population was restricted to patients receiving at least two days of treatment. The study was terminated by the sponsor in October 2007 after the enrolment of 38 evaluable patients - 20 randomized to high dose AT and 18 to placebo, 27 treated for 2 days or more - out of 164 screened patients. Enrolment failures were mainly represented by requirement for immediate delivery and consent refusal (91 patients). The primary endpoint occurred in 15 of 38 patients (39.5%), with a relative risk in the AT arm of 0.85 (95% CI 0.42-1.75) and 0.79 (95% CI 0.30-2.11) in the ITT and PP populations, respectively. Living neonates in the two arms had similar weight at birth, Apgar scores, and duration of hospitalization in neonatal ICU. In mothers, AT supplementation was associated with reduced blood loss at delivery and with surrogate laboratory markers (LDH, d-dimer). The results of this markedly underpowered trial, albeit suggestive of a potential maternal benefit, cannot support high-dose AT supplementation to improve fetal/neonatal outcomes in early preeclampsia.

    In recent years, red yeast rice (RYR) supplements have been marketed aggressively as a natural way to lower cholesterol; however, the large majority of commercially available products have not been studied according to current research standards. In a double blind placebo controlled randomized trial, 52 physicians and their spouses with a total cholesterol level of > 200 mg/dL were randomly allocated to receive a RYR extract or placebo for 8 weeks. As a primary outcome measure, we compared the before-after difference in lipid levels between both groups. As secondary outcome measures we looked at side-effects, CK elevation and a change in cardiovascular risk. LDL (low density lipoprotein) cholesterol was lowered with 36 mg/dL (22%) and total cholesterol with 37 mg/dL (15%) in the intervention group. This result was statistically significant as compared to the control group, in which no reduction in total cholesterol and LDL was observed (p < 0.001). There was no marked difference in CK (creatine kinase)-elevation or reported side-effects between study groups. In 5/31 participants in the intervention group, the lipid lowering effect resulted in lower cardiovascular risk as measured with SCORE (Systematic COronary Risk Evaluation). The RYR formulation under study was effective in lowering cholesterol and LDL cholesterol in this study population. RYR therapy may be an attractive and relatively well studied alternative in patients who are intolerant for statins or who have objections against pharmacological lipid lowering. However, consumers need to be warned that the actual content of commercially available preparations is not assured by governmental regulations, which raises effectiveness and safety issues.

    Cannabis dependence is a substantial public health problem. Behavioral treatments have shown promise, but there are no effective medications for cannabis dependence. The purpose of this study was to evaluate the safety and efficacy of dronabinol, a synthetic form of delta-9-tetrahydrocannabinol, a naturally occurring pharmacologically active component of marijuana, in treating cannabis dependence. 156 cannabis-dependent adults were enrolled in a randomized, double-blind, placebo-controlled, 12-week trial. After a 1-week placebo lead-in phase, participants were randomized to receive dronabinol 20mg twice a day or placebo. Doses were maintained until the end of week 8 and then tapered off over 2 weeks. All participants received weekly motivational enhancement and relapse prevention therapy. Marijuana use was assessed using the timeline follow back method. There was no significant difference between treatment groups in the proportion of participants who achieved 2 weeks of abstinence at the end of the maintenance phase (dronabinol: 17.7%; placebo: 15.6%). Although both groups showed a reduction in marijuana use over time, there were no differences between the groups. Treatment retention was significantly higher at the end of the maintenance phase on dronabinol (77%), compared to placebo (61%) (P=.02), and withdrawal symptoms were significantly lower on dronabinol than placebo (P=.02). This is the first trial using an agonist substitution strategy for treatment of cannabis dependence. Dronabinol showed promise, it was well-tolerated, and improved treatment retention and withdrawal symptoms. Future trials might test higher doses, combinations of dronabinol with other medications with complementary mechanisms, or with more potent behavioral interventions.

    Previous literature has shown that propofol has ideal anesthetic properties for patients undergoing colonoscopy, a common procedure at outpatient surgery centers. However, there is a paucity of information regarding patient satisfaction with propofol. The aim of this study was to evaluate patient satisfaction with propofol compared with nonpropofol (fentanyl/midazolam) anesthesia for outpatient colonoscopies. Safety and complications were secondary end points. This study was a double-blind, randomized, parallel-group controlled clinical trial (NCT 02937506). This study was conducted at a single ambulatory surgery center at an urban teaching community health system. Patients were scheduled for outpatient colonoscopy. Those with high-risk cardiac or pulmonary disease were excluded. Anesthesia personnel administered either fentanyl/midazolam (n = 300) or propofol (n = 300) for sedation during outpatient colonoscopy. A single, highly experienced endoscopist performed all colonoscopies. The primary outcomes measured were patient satisfaction (5-point Likert scale) and procedure complications. Data were collected on the day of endoscopy by the nursing staff of the postanesthesia care unit. A subinvestigator blinded to the randomization called patients 24 to 72 hours after discharge to obtain data on postprocedure problems and status of resumption of normal activities. Analysis was intention-to-treat. Fewer patients who received propofol remembered being awake during the procedure (2% vs 17% for fentanyl, p propofol (p propofol group (2.7% vs 11.7%, p propofol over a combination of fentanyl/midazolam as their anesthetic for outpatient colonoscopies. From a patient and provider perspective, propofol appears to be superior to fentanyl/midazolam for outpatient colonoscopy. See Video Abstract at http://links.lww.com/DCR/A445.

    This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was -0.4% (95% confidence interval, -9.8% to 9.1%), which was above the non-inferiority margin of -14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670). © 2017 The Korean Academy of Medical Sciences.

Two different doses of NR and a placebo were tested, the randomization was stratified by Latent Tuberculosis Infection (LTBI-positive (n = 21 and LTBI-negative subjects (n = 30. Each subject received 14 drinkable daily doses for 2 weeks.All patients completed the study. The 46.3% of the overall reported adverse events (AE were considered related to the investigational treatment. None of them were severe (94% were mild and 6% moderate. No statistical differences were found when comparing the median number of AE between the placebo group and both treatment groups. The most common AE reported were gastrointestinal events, most frequently mild abdominal pain and increase in stool frequency. Regarding the immunogenic response, both LTBI-negative and LTBI-positive volunteers treated with NR experienced a global increase on the Treg response, showed both in the population of CD25+CD39-, mainly effector Treg cells, or CD25+CD39+ memory PPD-specific Treg cells.This clinical trial demonstrates an excellent tolerability profile of NR linked to a significant increase in the population of specific effector and memory Tregs in the groups treated with NR in both LTBI-positive and negative subjects. NR shows a promising profile to be used to reduce the risk of active TB.

    Supplemental selenium (Se) may affect the clinical course of Graves disease (GD). Evaluate efficacy of add-on Se on medical treatment in GD. Double-blind, placebo-controlled, randomized supplementation trial. Academic endocrine outpatient clinic. Seventy untreated hyperthyroid patients with GD. Additionally to methimazole (MMI), patients received for 24 weeks either sodium selenite 300 µg/d po or placebo. MMI was discontinued at 24 weeks in euthyroid patients. Response rate (week 24), recurrence rate (week 36), and safety. A response was registered in 25 of 31 patients (80%) and in 27 of 33 (82%) at week 24 [odds ratio (OR) 0.93; 95% confidence interval (CI), 0.26 to 3.25; P = 0.904] in the Se (+MMI) and placebo (+MMI) groups, respectively. During a 12-week follow-up, 11 of 23 (48%) and 12 of 27 (44%) relapsed (OR 1.13; 95% CI, 0.29 to 2.66; P = 0.81) in the Se and placebo groups, respectively. Serum concentrations of Se and selenoprotein P were unrelated to response or recurrence rates. At week 36, 12 of 29 (41%) and 15 of 33 (45%) were responders and still in remission in the Se and placebo groups, respectively (OR 0.85; 95% CI, 0.31 to 2.32; P = 0.80). Serum levels of free triiodothyronine/free tetraiodothyronine, thyroid-stimulating hormone receptor antibody, prevalence of moderate to severe Graves orbitopathy, thyroid volume, and MMI starting dose were significantly lower in responders than in nonresponders. A total of 56 and 63 adverse events occurred in the Se and placebo groups, respectively (P = 0.164), whereas only one drug-related side effect (2.9%) was noted in 35 patients on placebo + MMI. Supplemental Se did not affect response or recurrence rates in GD.

    Postpoliomyelitis syndrome (PPS) is likely due to degeneration and dysfunction of terminal axons of enlarged postpolio motor units. Age-related decline in growth hormone and insulin-like growth factor (IGF-I) may be a contributing factor. Neuromuscular junction abnormalities and decreased IGF-I levels may respond to the anticholinesterase pyridostigmine, with consequent improvement in strength, fatigue, and quality of life. To determine the effect of pyridostigmine in PPS on health-related quality of life, isometric muscle strength, fatigue, and serum IGF-I levels; and to assess the safety of pyridostigmine in PPS. The study was a multicenter, randomized, double-blinded, placebo-controlled trial of a 6-month course of pyridostigmine 60 mg three times per day in 126 PPS patients. The primary data analysis compared mean changes of outcomes between treatment and control groups at 6 months using an intention to treat approach. Secondary analyses included a comparison of outcomes at 6 and 10 weeks, and in compliant patients. The study showed no significant differences in pyridostigmine and placebo-treated patients with regard to changes in quality of life, isometric strength, fatigue, and IGF-I serum levels at 6 months in the primary analysis and in compliant patients. There were no differences in outcomes at 6 and 10 weeks between groups. However, very weak muscles (1 to 25% predicted normal at baseline) were somewhat stronger (p = 0.10, 95% CI of difference -9.5 to 73.3%), and in compliant patients IGF-I was somewhat increased (p = 0.15, 95% CI of difference -6.4 to 44.8 ng/mL) at 6 months with the medication. Pyridostigmine was generally well tolerated. This study showed no significant differences between pyridostigmine and placebo-treated PPS patients on measures of quality of life, isometric strength, fatigue, and serum IGF-I.

    For important reasons, lorazepam (Ativan) and chlordiazepoxide (Librium) are both popular treatments for alcohol-withdrawal syndrome. Nevertheless, there is little literature directly comparing the two drugs. A formal comparison is desirable because of pharmacokinetic and other differences that could affect safety and efficacy considerations relevant to practice in developing countries. One hundred consecutive consenting male inpatients in a state of moderately severe, uncomplicated alcohol withdrawal at screening were randomized to receive either lorazepam (8 mg/day) or chlordiazepoxide (80 mg/day) with dosing down-titrated to zero in a fixed-dose schedule across 8 treatment days. Double-blind assessments of withdrawal-symptom severity and impairing adverse events were obtained during treatment and for 4 days afterward. One chlordiazepoxide patient developed withdrawal delirium. Lorazepam and chlordiazepoxide showed similar efficacy in reducing symptoms of alcohol withdrawal as assessed using the revised Clinical Institute Withdrawal Assessment for Alcohol scale. During withdrawal, irritability and dizziness were more common with lorazepam, and palpitations were more common with chlordiazepoxide. No difficulties in drug discontinuation or differences in impairing adverse events were observed with either drug. With the treatment schedule used in this study, lorazepam is as effective as the more traditional drug chlordiazepoxide in attenuating uncomplicated alcohol withdrawal. Lorazepam, therefore, could be used with confidence when liver disease or the inability to determine liver function status renders chlordiazepoxide therapy problematic. The absence of clinically significant withdrawal complications with lorazepam in this large study contrasts with findings from previously published studies and suggests that higher doses of lorazepam than those formerly used may be necessary during alcohol withdrawal.

    To determine the efficacy of a 14-day regimen of esomeprazole 20 mg for the treatment of frequent heartburn in subjects who are likely to self-treat with over-the-counter medications without consulting a health care provider. Adults with frequent heartburn ≥ 2 days per week in the past 4 weeks were randomly assigned to 14-day double-blind treatment with esomeprazole 20 mg once daily or placebo in 2 identical multicenter studies (ClinicalTrials.gov identifiers: NCT01370525, NCT01370538). The primary efficacy outcome was percentage of heartburn-free 24-hour days across 14 days. Secondary efficacy outcomes included heartburn resolution, defined as heartburn ≤ 2 days over 14 days, and percentages of subjects reporting ≤ 1 day with heartburn in the first and final weeks of treatment. Subjects recorded data in daily self-assessment diaries. The percentage of heartburn-free 24-hour days over 14 days was significantly higher (P esomeprazole 20 mg compared with placebo in study 1 (N = 331; 46.13% vs. 33.07%, respectively) and study 2 (N = 320; 48.00% vs 32.75%, respectively). Significantly more subjects treated with esomeprazole 20 mg had heartburn resolution over 14 days and in the first and final weeks compared with placebo. Within the first 4 days, the proportion of subjects with heartburn-free days was significantly greater with esomeprazole 20 mg versus placebo. Treatment was generally well tolerated, with a safety pattern consistent with the known profile for esomeprazole. A 14-day regimen of esomeprazole 20 mg once daily was effective for treating frequent heartburn in subjects who are likely to self-treat with over-the-counter medications.

    To assess the effect of treatment with febuxostat versus placebo on joint damage in hyperuricemic subjects with early gout (1 or 2 gout flares). In this double-blind, placebo-controlled study, 314 subjects with hyperuricemia (serum uric acid [UA] level of ≥7.0 mg/dl) and early gout were randomized 1:1 to receive once-daily febuxostat 40 mg (increased to 80 mg if the serum UA level was ≥6.0 mg/dl on day 14) or placebo. The primary efficacy end point was the mean change from baseline to month 24 in the modified Sharp/van der Heijde erosion score for the single affected joint. Additional efficacy end points included change from baseline to month 24 in the Rheumatoid Arthritis Magnetic Resonance Imaging Scoring (RAMRIS) scores for synovitis, erosion, and edema in the single affected joint, the incidence of gout flares, and serum UA levels. Safety was assessed throughout the study. Treatment with febuxostat did not lead to any notable changes in joint erosion over 2 years. In both treatment groups, the mean change from baseline to month 24 in the modified Sharp/van der Heijde erosion score for the single affected joint was minimal, with no between-group differences. However, treatment with febuxostat significantly improved the RAMRIS synovitis score at month 24 compared with placebo treatment (change from baseline -0.43 versus -0.07; P gout flares (29.3% versus 41.4%; P gout flares in subjects with early gout. © 2017 The Authors.

    The aim of this study was to evaluate the efficacy and safety of herbal dental cream in comparison to fluoride dental cream. Clinical evaluation of a novel herbal dental cream in plaque formation: a double-blind, randomized, controlled clinical trial. One hundred and two patients with established dental plaque were randomly assigned to either herbal dental group or fluoride dental group for six weeks in a double-blind design. Improvement in plaque index, oral hygiene status, bleeding index, and gingival index was evaluated in these patients along with microbiological study. Results indicated a significant reduction in plaque index, gingival index, oral hygiene index, and microbial growth in both groups. Difference between the groups was not significant. There was no significant change in bleeding index. No adverse events were reported and both the dental creams were well tolerated. The finding of this preliminary study indicates that herbal dental cream is as safe and effective as fluoride dental cream, but not superior to it.

    A randomized double-blind study with a 3-yr follow-up comparing the two arms "orchiectomy + Anandron (300 mg)" vs "orchiectomy + placebo" in 125 patients with stage D prostate cancer has confirmed the beneficial effects of the combined Anandron therapy on subjective parameters and on the best objective response (NPCP criteria), although these effects were not statistically significant, but failed to detect any improvement in time-to-disease progression or survival. Comparison with the results of other trials emphasizes the urgent need to establish suitable prognostic factors by further clinical research before evaluating the benefits of individual drugs.

    To evaluate the clinical and bacteriological efficacy of topical retapamulin ointment 1% versus oral linezolid in the treatment of patients with secondarily infected traumatic lesions (SITLs; excluding abscesses) or impetigo due to methicillin-resistant Staphylococcus aureus (MRSA). A randomized, double-blind, double-dummy, multicenter, comparative study (NCT00852540). Patients recruited from 36 study centers in the United States. Patients 2 months or older with SITL (including secondarily infected lacerations or sutured wounds) or impetigo (bullous and nonbullous) suitable for treatment with a topical antibiotic, with a total Skin Infection Rating Scale score of 8 or greater, including a pus/exudate score of 3 or greater. Patients received retapamulin ointment 1% (plus oral placebo), twice daily for 5 days or oral linezolid (plus placebo ointment) 2 or 3 times daily for 10 days. Primary end point: clinical response (success/failure) at follow-up in patients with MRSA at baseline (per-protocol population). Secondary efficacy end points: clinical and microbiologic response and outcome at follow-up and end of therapy; therapeutic response at follow-up. The majority of patients had SITL (70.4% [188/267] and 66.4% [91/137] in the retapamulin and linezolid groups, respectively; intent-to-treat clinical population). Clinical success rate at follow-up was significantly lower in the retapamulin versus the linezolid group (63.9% [39/61] vs 90.6% [29/32], respectively; difference in success rate -26.7%; 95% CI, -45.7 to -7.7). Clinical success rate at follow-up in the per-protocol MRSA population was significantly lower in the retapamulin versus the linezolid group. It could not be determined whether this was related to study design, bacterial virulence, or retapamulin activity.

    The aim of this double-blind, placebo-controlled study was to evaluate the efficacy and tolerability of ziprasidone in the treatment of adult patients with borderline personality disorder. Sixty DSM-IV borderline personality disorder patients were included from March 2004 to April 2006 in a 12-week, single-center, double-blind, placebo-controlled study. The subjects were randomly assigned to ziprasidone or placebo in a 1:1 ratio following a 2-week baseline period. The Clinical Global Impressions scale for use in borderline personality disorder patients (CGI-BPD) was the primary outcome measure, and other scales and self-reports related to affect, behavior, psychosis, general psychopathology domains, and clinical safety were included. Analysis of variance indicated no statistically significant differences between ziprasidone and placebo in the CGI-BPD. Nor were significant differences observed between groups in depressive, anxiety, psychotic, or impulsive symptoms. The mean daily dose of ziprasidone was 84.1 mg/day (SD = 54.8; range, 40-200). The drug was seen to be safe, and no serious adverse effects were observed. This trial failed to show a significant effect of ziprasidone in patients with borderline personality disorder. clinicaltrials.gov Identifier: NCT00635921.

    Individuals with Down syndrome (DS) have decreased cholinergic function and an uneven profile of cognitive abilities, with more pronounced deficits in learning, memory, and expressive language. Cholinesterase inhibitors may improve cognitive function in adults and adolescents with DS, but studies in children with DS have been limited. This study aimed to: (i) investigate the safety and efficacy of rivastigmine treatment; (ii) build upon our open-label studies in children with DS in a double-blind, placebo-controlled clinical trial; and (iii) investigate specific cognitive domains that may respond to rivastigmine treatment. We conducted a 20-week double-blind, placebo-controlled trial to investigate the safety and efficacy of rivastigmine in 22 children and adolescents with DS aged 10-17 years. Safety measures included reports of adverse events, laboratory parameters, and electrocardiograms. Efficacy measures included parental assessments of adaptive behavior and executive function, and direct measures of language and memory. No group differences were found on safety measures and 22 of 24 participants that passed study screening completed the study. The results did not demonstrate evidence for significant improvement in aspects of cognition, language, or overall function in the children receiving rivastigmine. Our results suggest that rivastigmine is safe and well-tolerated for children and adolescents with DS, but may not be effective for improving performance on the selected measures in this study. However, larger samples and/or alternate measures could possibly reveal improvements in cognitive function with rivastigmine treatment. Further research is needed to define a battery of cognitive measures that is sensitive to treatment effects in DS. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Dexmedetomidine (DEX) is increasingly being used as a sedative for monitored anesthesia care (MAC) because of its analgesic properties, "cooperative sedation," and lack of respiratory depression. In this randomized, multicenter, double-blind, Phase III Food and Drug Administration study, we evaluated the safety and efficacy of two doses of DEX for sedation of patients undergoing a broad range of surgical or diagnostic procedures requiring MAC. Three hundred twenty-six patients were randomized 2:2:1 to DEX 0.5 microg/kg, DEX 1 microg/kg, or saline placebo initial loading dose, followed by a maintenance infusion of 0.2-1.0 microg x kg(-1) x h(-1) of DEX (or equivalent volume of saline) titrated to a targeted level of sedation ( 4 and fentanyl for pain. The primary end-point was the percentage of patients not requiring rescue midazolam. Significantly fewer patients in the 0.5- and 1-microg/kg DEX groups required supplemental midazolam compared with placebo (59.7% [80/134], 45.7% [59/129] vs 96.8% [61/63], respectively; P < 0.001) and at lower doses to achieve an OAA/S < or = 4 before and during surgery compared with the saline group (1.4 and 0.9 mg vs 4.1 mg, respectively; P < 0.001, each group compared with placebo). Both DEX groups required significantly less fentanyl (84.8 and 83.6 microg vs 144.4 microg, respectively; P < 0.001, for both DEX groups versus placebo) for all surgical subtypes. Anesthesiologists indicated significantly increased ease of achieving and maintaining targeted sedation in both DEX groups compared with placebo with midazolam (P < 0.001). Patient satisfaction was significantly higher with DEX (P < or = 0.009, both groups versus placebo). Common adverse events with DEX were protocol-defined bradycardia and hypotension that were predominately mild to moderate in severity. The incidence of clinically significant respiratory depression (defined as a respiratory rate of < 8 or an oxygen saturation of < 90%) was lower in DEX-treated patients (P = 0

    The benefits of clinical neurofeedback training are well known, however, its adverse side-effects are less studied. This research focuses on the transient adverse side effects of neurofeedback training via a double-blind, sham/controlled methodology. Thirty healthy undergraduate students volunteers were randomly divided into three treatment groups: increasing a modified Sensory Motor Rhythm, increasing Upper Alpha, and Sham/control group who receive a random reward. The training sessions were administered for a total of ten sessions. Questionnaires of transient adverse side effects were completed by all volunteers before each session. The results suggest that similar to most medical treatments, neurofeedback can cause transient adverse side effects. Moreover, most participants reported experiencing some side effects. The side effects can be divided into non-specific side effect, associated with the neurofeedback training in general and specific ones associated with the particular protocol. Sensory Motor Rhythm protocol seems to be the most sensitive to side effects.

    Male and female pattern hair loss are common, chronic dermatologic disorders with limited therapeutic options. In recent years, a number of commercial devices using low-level laser therapy have been promoted, but there have been little peer-reviewed data on their efficacy. To determine whether treatment with a low-level laser device, the US FDA-cleared HairMax Lasercomb®, increases terminal hair density in both men and women with pattern hair loss. Randomized, sham device-controlled, double-blind clinical trials were conducted at multiple institutional and private practices. A total of 146 male and 188 female subjects with pattern hair loss were screened. A total of 128 male and 141 female subjects were randomized to receive either a lasercomb (one of three models) or a sham device in concealed sealed packets, and were treated on the whole scalp three times a week for 26 weeks. Terminal hair density of the target area was evaluated at baseline and at 16- and 26-week follow-ups, and analyzed to determine whether the hypothesis formulated prior to data collection, that lasercomb treatment would increase terminal hair density, was correct. The site investigators and the subjects remained blinded to the type of device they dispensed/received throughout the study. The evaluator of masked digital photographs was blinded to which trial arm the subject belonged. Seventy-eight, 63, 49, and 79 subjects were randomized in four trials of 9-beam lasercomb treatment in female subjects, 12-beam lasercomb treatment in female subjects, 7-beam lasercomb treatment in male subjects, and 9- and 12-beam lasercomb treatment in male subjects, compared with the sham device, respectively. Nineteen female and 25 male subjects were lost to follow-up. Among the remaining 122 female and 103 male subjects in the efficacy analysis, the mean terminal hair count at 26 weeks increased from baseline by 20.2, 20.6, 18.4, 20.9, and 25.7 per cm2 in 9-beam lasercomb-treated female subjects, 12-beam

    Rhodiola rosea (R. rosea), a botanical of both western and traditional Chinese medicine, has been used as a folk remedy for improving stamina and reducing stress. However, few controlled clinical trials have examined the safety and efficacy of R. rosea for the treatment of major depressive disorder (MDD). This study seeks to evaluate the safety and efficacy of R. rosea in a 12-week, randomized, double-blind, placebo-controlled, parallel group study design. Subjects with MDD not receiving antidepressant therapy will be randomized to either R. rosea extract 340-1,360 mg daily; sertraline 50-200 mg daily, or placebo for 12 weeks. The primary outcome measure will be change over time in the mean 17-item Hamilton Depression Rating score. Secondary outcome measures will include safety and quality of life ratings. Statistical procedures will include mixed-effects models to assess efficacy for primary and secondary outcomes. This study will provide valuable preliminary information on the safety and efficacy data of R. rosea versus conventional antidepressant therapy of MDD. It will also inform additional hypotheses and study design of future, fully powered, phase III clinical trials with R. rosea to determine its safety and efficacy in MDD.

A double-blind randomized trial included 23 selected patients with a confirmed diagnosis of tubal pregnancy who met the inclusion criteria (hemodynamic stability, initial serum β-hCG concentration 0.999). The β-hCG values became undetectable at 22 ± 15.4 days in the methotrexate group and 20.6 ± 8.4 days in the placebo group (p = 0.80). This study showed no statistically significant difference between the treatment with methotrexate and placebo, with similar success rates and similar time interval for β-hCG to become undetectable.

    Hyperpolarization-activated, cyclic nucleotide-gated 4 (HCN4) channels comprise the final pathway for autonomic heart rate (HR) regulation. We hypothesized that HCN4 inhibition could reverse autonomic imbalance in a human model of cardiac sympathetic activation. Nineteen healthy men ingested oral metoprolol+reboxetine, ivabradine+reboxetine, or placebo+reboxetine in a double-blind, randomized, crossover fashion. We assessed HR, blood pressure (BP), stroke volume, and cardiac output during rest and profound orthostatic stress. HR variability, BP variability, and baroreflex sensitivity were analyzed. Metoprolol, but not ivabradine, decreased resting HR and BP. Ivabradine attenuated the HR increase to orthostatic stress, albeit to a lesser extent than metoprolol. Stroke volume and cardiac output at a given HR were significantly lower with metoprolol. Unlike metoprolol, ivabradine did not affect HR variability, BP variability, or baroreflex sensitivity. Ivabradine attenuates sympathetic influences on HR at the sinus node level, leaving myocardial sympathetic activation unopposed. Reversal of parasympathetic dysfunction by ivabradine appears limited.

    Ciguatera poisoning (CP) is worldwide the most common fish-borne illness and one of the most common forms of nonbacterial food poisoning. IV mannitol is considered the treatment of choice for CP but has not been evaluated in a double-blind randomized trial. A prospective clinical study of 50 patients with CP on Rarotonga, Cook Islands, was conducted to better define the neurologic picture of CP and to study the effect of mannitol or normal saline under double-blind randomized conditions over a 24-hour period. The neurologic presentation of CP was that of a predominantly sensory, length-dependent polyneuropathy, with preferential small-fiber involvement. Motor paresis, cranial nerve dysfunction, and CNS abnormalities were absent but for a rare mild transitory cerebellar syndrome. At 24 hours, 96% of mannitol-treated patients and 92% of normal saline-treated patients had some improvement of symptoms (p = 1.0), whereas 12% and 24% of patients in each group were asymptomatic (p = 0.46). By 24 hours, the prevalence of the various polyneuropathic symptoms and signs was reduced roughly by half in both groups. Discomfort or pain along the vein used for infusion was more frequent in the mannitol group (84%) than in the normal saline group (36%) (p = 0.0015). Mannitol was not superior to normal saline in relieving symptoms and signs of CP at 24 hours in this study population but had more side effects. These results do not support single-dose mannitol as standard treatment for CP.

    Background: Cosmeceutical products represent an increasingly important therapeutic option for anti-aging and rejuvenation, either used alone or in combination with dermatologic surgical procedures. Among this group of products, topical growth factors have demonstrated efficacy in randomized, controlled clinical trials. However, comparisons between different products remain uncommon. Objective: The objective of this randomized, double-blind, split-face clinical trial was to compare two different topical growth factor formulations derived from either human fibroblasts or human adipose tissue derived mesenchymal stem cells. Methods: This was an institutional review board-approved, randomized, double-blind, split-face clinical trial involving 20 healthy subjects with moderate-to-severe facial wrinkling secondary to photodamage. One half of the face was randomized to receive topical human fibroblast growth factors and the other topical human mesenchymal stem cell growth factors. Treatment was continued for three months, and evaluations were performed in a double-blind fashion. Results: Both growth factor formulations achieved significant improvement in facial wrinkling. Blinded investigator and subject evaluations did not detect any significant differences between the two formulations in terms of efficacy, safety, or tolerability. Conclusion: Both human fibroblast growth factors and human mesenchymal stem cell growth factors are effective at facial rejuvenation. Topical growth factors represent a useful therapeutic modality.

    To investigate whether laser acupuncture is efficacious in children with headache and if active laser treatment is superior to placebo laser treatment in a prospective, randomized, double-blind, placebo-controlled trial of low level laser acupuncture in 43 children (mean age (SD) 12.3 (+/-2.6) years) with headache (either migraine (22 patients) or tension type headache (21 patients)). Patients were randomized to receive a course of 4 treatments over 4 weeks with either active or placebo laser. The treatment was highly individualised based on criteria of Traditional Chinese medicine (TCM). The primary outcome measure was a difference in numbers of headache days between baseline and the 4 months after randomization. Secondary outcome measures included a change in headache severity using a 10 cm Visual Analogue Scale (VAS) for pain and a change in monthly hours with headache. Measurements were taken during 4 weeks before randomization (baseline), at weeks 1-4, 5-8, 9-12 and 13-16 from baseline. The mean number of headaches per month decreased significantly by 6.4 days in the treated group (pmeasures headache severity and monthly hours with headache decreased as well significantly at all time points compared to baseline (pchildren with headache with active laser treatment being clearly more effective than placebo laser treatment.

    Fluid overload refractory to loop diuretic therapy can complicate acute or chronic heart failure (HF) management. The Safety and Efficacy of the Combination of Loop with Thiazide-type Diuretics in Patients with Decompensated Heart Failure (CLOROTIC) trial (Clinicaltrials.gov identifier NCT01647932) will test the hypothesis that blocking distal tubule sodium reabsorption with hydrochlorothiazide can antagonize the renal adaptation to chronic loop diuretic therapy and improve diuretic resistance. CLOROTIC is a randomized, placebo-controlled, double-blind, multicenter study. Three hundred and four patients with decompensated HF will be randomly assigned to receive hydrochlorothiazide or placebo in addition to a furosemide regimen. The main inclusion criteria are: age ≥18 years, history of chronic HF (irrespective of etiology and/or ejection fraction), admission for acute decompensation, and previous treatment with an oral loop diuretic for at least 1 month before randomization. The 2 coprimary endpoints are changes in body weight and changes in patient-reported dyspnea during hospital admission. Morbidity, mortality, and safety aspects will also be addressed. CLOROTIC is the first large-scale trial to evaluate whether the addition of a thiazide diuretic (hydrochlorothiazide) to a loop diuretic (furosemide) is a safe and effective strategy for improving congestive symptoms resulting from HF. This trial will provide important information and will therefore have a major impact on treatment strategies and future trials in these patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    Studies in adults have shown that postprocedural abdominal pain is reduced with the use of carbon dioxide (CO(2)) instead of air for insufflation during colonoscopy. The aim of our study was to compare postprocedural abdominal pain and girth in children undergoing colonoscopy using CO(2) or air for insufflation. This was a prospective, randomized, double-blind study that included 76 consecutive pediatric patients undergoing colonoscopy for various indications. Patients were randomly assigned to either CO(2) or air insufflation. At 2, 4, and 24 hours after the examination, the patients' pain was assessed by using the 11-point numerical rating scale. The waist circumference was measured 10 minutes and 2 and 4 hours after colonoscopy. A significantly higher proportion of patients had no pain after colonoscopy in the CO(2) group compared with the air group (82 vs 37% at 2 hours and 95% vs. 63% at 4 hours, P < .001). Mean abdominal pain scores 2 and 4 hours after the procedure were statistically significantly lower in the CO(2) group compared with the control air group (0.5 vs 2.6 at 2 hours and 0.1 vs 1.2 at 4 hours, P < .001). There was no difference in waist circumference between the 2 groups at all time intervals. The results of this randomized trial show clear benefits of CO(2) insufflation for colonoscopy in reducing postprocedural discomfort. ( NCT02407639.).

    In a sham-controlled double-blind trial, we aim to establish the efficacy and safety of the local application of laser therapy in patients with diabetes, onychomycosis and risk factors for diabetes-related foot complications. Onychomycosis leads to thickened and distorted nails, which in turn lead to increased local pressure. The combination of onychomycosis and neuropathy or peripheral arterial disease (PAD) increases the risk of developing diabetes-related foot complications. Usual care for high-risk patients with diabetes and onychomycosis is completely symptomatic with frequent shaving and clipping of the nails. No effective curative local therapies exist, and systemic agents are often withheld due to concerns for side effects and interactions. The primary aim is to evaluate the efficacy of four sessions of Nd:YAG 1064 nM laser application on the one-year clinical and microbiological cure rate in a randomized, double-blind, sham-controlled design with blinded outcome assessment. Mandatory inclusion criteria are diagnosis of diabetes, risk factors for developing foot ulcers defined as a modified Simm's classification score 1 or 2 and either neuropathy or PAD. A total of 64 patients are randomized to intervention or sham treatment performed by a podiatrist. This study will be the first double-blind study that investigates the effects of local laser therapy on onychomycosis, specifically performed in patients with diabetes with additional risk factors for foot complications.

    Ulcerative colitis (UC) is a condition characterized by chronic inflammation of the colon and is related to a genetically and environmentally-generated altered immune response to the enteric microbiome. Previous work in the PI laboratory suggests that children with UC harbor a unique gut microbial profile, which can predict therapeutic response. We hypothesized that children with ulcerative colitis will benefit from fecal transplant therapy (FMT). To this date there have been a number of reports describing the role of FMT in this disease albeit without uniform success and without controlled pediatric studies. Therefore, there is a strong need to determine its safety and efficacy in controlled trials. We report pilot data in a randomized, double-blinded, controlled study to evaluate the safety and efficacy of FMT from healthy donor versus placebo (subject's own stools) in combination with 5-ASA in mild to moderate disease. Twelve children were randomized to receive FMT or placebo. Subjects were monitored for 12 months. Remission or a 20-point improvement of PUCAI scores were seen in 60% of children receiving FMT versus 28% receiving placebo. More importantly, children receiving FMT did not require escalation of therapy in contrast to 71% receiving placebo. No serious adverse events related to FMT. Bloating and fever were adverse events that were considered related to FMT. To summarize, there appears to be a prospect of benefit in this small number of children receiving FMT for mild to moderate ulcerative colitis. FMT appeared to be safe in this patient population.

    Full Text Available Eighty male patients with AGA, not treated in the previous 6 months were enrolled in this randomized, double blind, placebo controlled trial to assess the safety and efficacy of finasteride, 1mg daily, on hair growth. Patients were randomized into 2 groups: Group 1 received 1 mg of finasteride daily and Group 2 received a placebo for a period of 12 months. Efficacy was assessed by hair counts, photographic records, patient′s self-assessment questionnaire and clinical assessment. Safety was assessed by history taking and laboratory parameters. A total of 39 patients completed the study. Finasteride was rated superior to placebo with respect to all efficacy measures. At the end of study, finasteride treated patients had a mean increase of 20.56±4.73 hairs compared to a decrease of 9.56±5.53 hairs in placebo treated patients. Photographically, 69.56% of finasteride treated patients were rated as improved at 12 months compared to only 6.25% of placebo treated patients. Ten (25% of finasteride treated patients developed adverse effects (5-decreased libido as well as erectile dysfunction, 4-erectile dysfunction, 1-decreased libido. Finasteride in comparison to placebo was effective in promoting hair growth in male patients of AGA. However, the side effects to the drug were high in this study.

    Background. We for the first time examined the effects of a multiherb formula containing Crataegus pinnatifida (1 g daily), Alisma orientalis, Stigma maydis, Ganoderma lucidum, Polygonum multiflorum, and Morus alba on plasma lipid and glucose levels in Chinese patients with dyslipidemia. Methods. In this randomized, double-blind, placebo-controlled study, 42 patients were randomized at a ratio of 1 : 1 to receive the herbal formula or placebo for 12 weeks and 40 patients completed the study. Lipid profiles, glucose, glycated haemoglobin (HbA1c), and laboratory safety parameters were performed before and after treatment. Results. The difference in the changes in low-density lipoprotein cholesterol (LDL-C) levels between placebo and active treatment (−9%) was significantly (P < 0.05) better with active treatment. HbA1c levels significantly decreased by −3.9% in the active treatment group, but the change was not significantly different from that with placebo (−1.1%) (P = 0.098). There were no apparent adverse effects or changes in laboratory safety parameters with either treatment. Conclusions. The multiherb formula had mild beneficial effects on plasma LDL-C after 12-weeks treatment in subjects with dyslipidemia without any noticeable adverse effects. PMID:24834096

    Full Text Available Abstract Background Platelet activation has been implicated in the pathogenesis of sickle cell disease (SCD suggesting antiplatelet agents may be therapeutic. To evaluate the safety of prasugrel, a thienopyridine antiplatelet agent, in adult patients with SCD, we conducted a double-blind, randomized, placebo-controlled study. Methods The primary endpoint, safety, was measured by hemorrhagic events requiring medical intervention. Patients were randomized to prasugrel 5 mg daily (n = 41 or placebo (n = 21 for 30 days. Platelet function by VerifyNow® P2Y12 and vasodilator-stimulated phosphoprotein assays at days 10 and 30 were significantly inhibited in prasugrel- compared with placebo-treated SCD patients. Results There were no hemorrhagic events requiring medical intervention in either study arm. Mean pain rate (percentage of days with pain and intensity in the prasugrel arm were decreased compared with placebo. However, these decreases did not reach statistical significance. Platelet surface P-selectin and plasma soluble P-selectin, biomarkers of in vivo platelet activation, were significantly reduced in SCD patients receiving prasugrel compared with placebo. In sum, prasugrel was well tolerated and not associated with serious hemorrhagic events. Conclusions Despite the small size and short duration of this study, there was a decrease in platelet activation biomarkers and a trend toward decreased pain.

    To test the hypothesis that chronic treatment of early-stage Huntington disease (HD) with high-dose coenzyme Q10 (CoQ) will slow the progressive functional decline of HD. We performed a multicenter randomized, double-blind, placebo-controlled trial. Patients with early-stage HD (n = 609) were enrolled at 48 sites in the United States, Canada, and Australia from 2008 to 2012. Patients were randomized to receive either CoQ 2,400 mg/d or matching placebo, then followed for 60 months. The primary outcome variable was the change from baseline to month 60 in Total Functional Capacity score (for patients who survived) combined with time to death (for patients who died) analyzed using a joint-rank analysis approach. An interim analysis for futility revealed a conditional power of <5% for the primary analysis, prompting premature conclusion in July 2014. No statistically significant differences were seen between treatment groups for the primary or secondary outcome measures. CoQ was generally safe and well-tolerated throughout the study. These data do not justify use of CoQ as a treatment to slow functional decline in HD. NCT00608881. This article provides Class I evidence that CoQ does not slow the progressive functional decline of patients with HD. © 2016 American Academy of Neurology.

    Acute alcohol withdrawal syndrome (AAWS) is encountered in patients presenting acutely to the Emergency Department (ED) and often requires pharmacologic management. We investigated whether a single dose of intravenous (i.v.) phenobarbital combined with a standardized lorazepam-based alcohol withdrawal protocol decreases intensive care unit (ICU) admission in ED patients with acute alcohol withdrawal. This was a prospective, randomized, double-blind, placebo-controlled study. Patients were randomized to receive either a single dose of i.v. phenobarbital (10 mg/kg in 100 mL normal saline) or placebo (100 mL normal saline). All patients were placed on the institutional symptom-guided lorazepam-based alcohol withdrawal protocol. The primary outcome was initial level of hospital admission (ICU vs. telemetry vs. floor ward). There were 198 patients enrolled in the study, and 102 met inclusion criteria for analysis. Fifty-one patients received phenobarbital and 51 received placebo. Baseline characteristics and severity were similar in both groups. Patients that received phenobarbital had fewer ICU admissions (8% vs. 25%, 95% confidence interval 4-32). There were no differences in adverse events. A single dose of i.v. phenobarbital combined with a symptom-guided lorazepam-based alcohol withdrawal protocol resulted in decreased ICU admission and did not cause increased adverse outcomes.

    Breath holding spells (BHS) are common paroxysmal non-epileptic events in the pediatric population which are very stressfull despite their harmless nature. There has been no specific treatment found for the spells yet. The aim of this study was to evaluate the efficacy of piracetam (2-oxo-l-pyrrolidine) on these children. In this randomized double blind clinical trial study, 150 children with severe BHS referred to our pediatric outpatient service were enrolled from August 2011 to July 2012. The patients were randomized into two equal groups. One received 40mg/kg/day piracetam and the other group received placebo, twice daily. Patients were followed monthly for three months. The number of attacks/month before and after treatment were documented. Of the enrolled patients, 86 were boys. The mean age of the patients was 17 months (range, 6 to 24 months). In the piracetam group, 1 month after treatment an 81% response to treatment was found. In the placebo group, none of the patients had complete remission and 7% of the cases had partial remission. Overall, control of breath-holding spells was observed in 91% of the patients in the group taking piracetam as compared with 16% in the group taking placebo at the end of the study. There was no significant difference detected between the groups regarding the prevalence of drug side effects. A significant difference was detected between piracetam and placebo in prevention and controlling BHS. Piracetam (40mg/kg/day) had a good effect on our patients.

    Prospective, randomized, double-blinded, clinical trial using a repeated-measures design. To determine the short-term clinical efficacy of Kinesio Tape (KT) when applied to college students with shoulder pain, as compared to a sham tape application. Tape is commonly used as an adjunct for treatment and prevention of musculoskeletal injuries. A majority of tape applications that are reported in the literature involve nonstretch tape. The KT method has gained significant popularity in recent years, but there is a paucity of evidence on its use. Forty-two subjects clinically diagnosed with rotator cuff tendonitis/impingement were randomly assigned to 1 of 2 groups: therapeutic KT group or sham KT group. Subjects wore the tape for 2 consecutive 3-day intervals. Self-reported pain and disability and pain-free active ranges of motion (ROM) were measured at multiple intervals to assess for differences between groups. The therapeutic KT group showed immediate improvement in pain-free shoulder abduction (mean +/- SD increase, 16.9 degrees +/- 23.2 degrees ; P = .005) after tape application. No other differences between groups regarding ROM, pain, or disability scores at any time interval were found. KT may be of some assistance to clinicians in improving pain-free active ROM immediately after tape application for patients with shoulder pain. Utilization of KT for decreasing pain intensity or disability for young patients with suspected shoulder tendonitis/impingement is not supported. Therapy, level 1b-.

    Open carpal tunnel decompression under local anesthesia is routinely done by many surgeons. However, patients complain of pain during the injection of local anesthesia. This prospective, double-blind, randomized study was to compare the pain visual analog scale (VAS) scores of local anesthesia using lidocaine with and without sodium bicarbonate in patients with bilateral carpal tunnel syndrome. Twenty-five patients underwent bilateral simultaneous carpal tunnel decompression. All had topical anesthetic cream applied on the palm and wrist before the lidocaine block. In a randomized manner, half of the hands were blocked with nonbuffered lidocaine and half were blocked with buffered lidocaine. Pain was evaluated on a VAS score. The mean pain VAS score in the hand with buffered lidocaine was 4.6 ± 1.5 and 6.5 ± 1.5 for the hand with nonbuffered lidocaine. After adjustment for individual threshold of the pain, the mean pain VAS score changed into 4.6 ± 1.3 with buffered lidocaine and 6.6 ± 1.7 without buffered lidocaine. In open carpal tunnel surgery, the use of buffered lidocaine for local anesthesia reduces the anesthetic pain effectively. Therapeutic I. Copyright © 2013 American Society for Surgery of the Hand.

In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery bypass graft surgery bleeding. METHODS: A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1 g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post-operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. RESULTS: There were no significant differences between intra-operative packed red blood cells infusion in the studied groups (1.0 ± 1.4 in fibrinogen group, and 1.3 ± 1.1 in control group. Less postoperative bleeding was observed in the fibrinogen group (477 ± 143 versus 703 ± 179, p = 0.0001. Fifteen patients in the fibrinogen group and 21 in the control group required post-op packed red blood cells infusion (p = 0.094. No thrombotic event was observed through 72 h after surgery. CONCLUSION: Prophylactic fibrinogen reduces post-operative bleeding in patients undergoing coronary artery bypass graft.

    Leukotriene receptor antagonists (LTRAs) are well established in the management of outpatient asthma. However, there is very little information as to their role in acute asthma exacerbations. We hypothesized that LTRAs may accelerate lung function recovery when given in an acute exacerbation. A randomized, double blind, placebo-controlled trial was conducted at the Aga Khan University Hospital to assess the efficacy of oral montelukast on patients of 16 years of age and above who were hospitalized with acute asthma exacerbation. The patients were given either montelukast or placebo along with standard therapy throughout the hospital stay for acute asthma. Improvements in lung function and duration of hospital stay were monitored. 100 patients were randomized; their mean age was 52 years (SD +/- 18.50). The majority were females (79%) and non-smokers (89%). The mean hospital stay was 3.70 ± 1.93 days with 80% of patients discharged in 3 days. There was no significant difference in clinical symptoms, PEF over the course of hospital stay (p = 0.20 at day 2 and p = 0.47 at day 3) and discharge (p = 0.15), FEV1 at discharge (p = 0.29) or length of hospital stay (p = 0.90) between the two groups. No serious adverse effects were noted during the course of the study. Our study suggests that there is no benefit of addition of oral montelukast over conventional treatment in the management of acute asthma attack. 375-Med/ERC-04.

    Full Text Available Introduction. Expresssion of tardive dyskinesia as one of the side effects of antipsychotic drugs causes various problems in psychotic patients. It is the main cause of patient"s drug incompliance.Vitamine E with it"s antioxidants properties might be an effective treatment for tardive dyskinesia. Methods. In a randomized double blind clinical trial, thirty inpatients of the psychiatric hospital in Isfahan were studied. Patients were stratified according to their age, psychiatric disorder and duration, intensity of tardive dyskinesia and antipsychotic dosage. Then they were asssigned randomly into two groups. Vitamine E (600 mg/day was administered to interventional group (15 patients. Another group received placebo (15 patients. Treatment durated for 6 weeks. Abnormal Involuntary Movment Scale (AIMS was used to measure tardive dyskinesia intensity. Results. Average of disorder intensity in those who received vit. E, dropped down from 8.33/10 (befor treatment to 6.13/10 (after treatment. It means 26.3 percent reduction of tardive dyskinesia intensity. This difference was only 7.3 percent in control group. There were no statistical diffrence between two groups after treatment (P>0.05. Discussion. There is no statistical efficacy for vitamine E in the management of tardive dyskinesia. But it is recommended to make another study with more samples.

    Topical corticosteroids are used to treat inflammation and relieve itching in atopic dermatitis, but their use is limited by adverse reactions. The main aim of this study was to investigate whether daily treatment with Polypodium leucotomos extract would reduce the use of topical corticosteroids in children and adolescents with atopic dermatitis. We also analyzed oral antihistamine use and changes in disease severity. We performed a phase IV randomized, double-blind, placebo-controlled, multicenter trial involving 105 patients aged between 2 and 17 years who were receiving topical corticosteroids to treat moderate atopic dermatitis. The patients were randomized to receive, in addition to their standard treatment, Polypodium leucotomos extract or placebo (both in capsule form) for 6 months. The percentage of days on which topical corticosteroids and other atopic dermatitis treatments were used was calculated. Use of Polypodium leucotomos extract did not significantly reduce the mean (SD) percentage of days on which topical corticosteroids were used (11% [12%] vs 12% [11%] for placebo). A significant reduction was, however, observed for oral histamine use (median percentage of days, 4.5% in the Polypodium leucotomos group and 13.6% in the placebo group [P= .038]). The percentage of patients who used oral antihistamines was also lower in the Polypodium leucotomos group. Long-term treatment with Polypodium leucotomos extract has benefits for children and adolescents with atopic dermatitis who require pharmacologic treatment to reduce inflammation and relieve itching.

    This double-blind randomized clinical trial evaluated tooth sensitivity (TS) and the effectiveness (EF) of two types of bleaching agents (Trèswhite Ortho [TWO] and Trèswhite Supreme [TWS]) when used in patients wearing orthodontic appliances. Forty patients between the ages of 18 and 40 years were randomly stratified, with an equal allocation rate, into two groups (n=20), according to the bleaching agent applied. Tooth color of the six maxillary anterior teeth was measured before and after the treatment with a spectrophotometer. The TS was recorded on three scales before and during the bleaching treatment. With regard to EF, a significant reduction was found (ranging from 7.3-9.6 and 5.3-9.5 Vita scale units for TWO and TWS, respectively, p0.63). The number of patients with sensitivity was 58.8% and 73.3% for TWO and TWS groups, respectively (p=0.53); however, with each of the three scales used, the intensity of sensitivity was low and there was no statistical difference between TWO and TWS (p>0.05). In spite of producing a side effect of low TS, the two bleaching treatments tested were effective for dental bleaching in patients with fixed orthodontic appliances.

    To evaluate the effects of hormone therapy (HT) on cognition and subjective quality of life (QoL) in recently postmenopausal women with cognitive complaints. Cognitive Complaints in Early Menopause Trial (COGENT) was a randomized, double-blind, placebo-controlled, multicenter, pilot study of 180 healthy postmenopausal women aged 45 to 55 years, randomly assigned to receive either placebo or conjugated equine estrogen 0.625 mg/medroxyprogesterone acetate 2.5 mg for 4 months. Outcome measures included memory, subjective cognition, QoL, sexuality, and sleep, which were assessed at baseline and month 4. The study was terminated before the expected final sample size of 275 due to a decrease in enrollment coinciding with the publication of findings from the Women's Health Initiative. There were no differences between groups on any cognitive or QoL measures, except for an increase in sexual interest and thoughts with HT. Modest negative effects on short- and long-term verbal memory approached significance (p or=0.45, this study suggests potential modest negative effects on verbal memory that are consistent with previous hormone therapy trials in older women.

    We sought to determine whether topical finasteride can enhance the efficacy of intense pulsed light hair removal. An intense pulsed light (IPL) treatment with radiofrequency (RF) was performed every four weeks, resulting in up to three sessions, and again at the end of the study - 6 months after the start of the experiment. Each patient also applied either finasteride or placebo solution twice daily to each side of the chin in a double-blinded manner. A total of 77 patients were included in the study. Mean hair density before treatment in finasteride side of the patient's chin was 19.7 ± 11.7 and in placebo side was 19.1 ± 11.3. After three sessions of IPL + RF treatment, combined with twice daily application of finasteride and placebo solutions, at the end of 6-month period mean hair density of 8 ± 6.3 and 9 ± 5.6 was achieved in finasteride and placebo side respectively. Statistically significant difference was found between finasteride and placebo solution. We have demonstrated that the addition of finasteride solution to IPL + RF hair removal may result in a more reduction of unwanted facial hair in women when the combination is used for up to 6 months.

    Treatment options for plantar fasciitis have resulted in varied patient outcomes. The aim of this study was to compare a novel treatment, cryopreserved human amniotic membrane (c-hAM), to a traditional treatment, corticosteroid. Our hypothesis was that c-hAM would be safe and comparable to corticosteroids for plantar fasciitis in regard to patient outcomes. A randomized, controlled, double-blind, single-center pilot study was completed. Patients were randomized into one of 2 treatment groups: c-hAM or corticosteroid. Patients received an injection at their initial baseline visit with an option for a second injection at their first 6-week follow-up. Total follow-up was obtained for 12 weeks after the most recent injection. The primary outcome measurement was the Foot Health Status Questionnaire (FHSQ). The secondary outcome measurements were the Visual Analog Scale (VAS) and verbally reported percentage improvement. Data were analyzed between groups for the 2 different cohorts (1 injection versus 2 injections). Twenty-three patients had complete follow-up. Fourteen were randomized to receive corticosteroid and 9 were randomized to receive c-hAM. Three patients in each group received second injections. With the numbers available, the majority of outcome measurements showed no statistical difference between groups. The corticosteroid did, however, have greater FHSQ shoe fit improvement (P = .0244) at 6 weeks, FHSQ general health improvement (P = .0132) at 6 weeks, and verbally reported improvement (P = .041) at 12 weeks in the one-injection cohort. Cryopreserved hAM had greater FHSQ foot pain improvement (P = .0113) at 18 weeks in the 2-injection cohort. Cryopreserved hAM injection may be safe and comparable to corticosteroid injection for treatment of plantar fasciitis. This is a pilot study and requires further investigation.

    The purpose of this study is to evaluate the efficacy and safety of an over-the-counter (OTC) 1% colloidal oatmeal cream versus a prescription barrier cream in children with mild-to-moderate atopic dermatitis (AD). Eligible patients (6 months-18 years) were randomized to OTC or prescription cream. Eczema Area and Severity Index (EASI) scores, Investigator's Global Atopic Dermatitis Assessment (IGADA) scores, patients' and/or caregivers' assessment of itch using 10-cm visual analog scale (VAS) on day 0, weeks 1, 2, and 3 were assessed. The intention to treat (ITT) and per protocol (PP) populations were analyzed. Ninety patients (mean [SD] age, 8.1 [4] years; boys, 45.6%; African American, 54.4%) were randomized (OTC cream, 45; prescription cream, 45). At week 3, EASI scores showed that the OTC cream was non-inferior (non-inferiority margin = 1.5) to the prescription cream (adjusted mean change [95% CI] from baseline: ITT, 0.18 [-0.35, 0.70]; PP, 0.14 [-0.42, 0.70]). IGADA (adjusted mean between group difference, 0.106 [-0.130, 0.341]) and VAS itch (0.103 [-0.831, 1.038]) scores improved in both groups. No safety issues were identified. OTC 1% oatmeal cream was equally effective and safe as the prescription barrier cream for the symptomatic treatment of mild-to-moderate AD in children. NCT01326910.

    Here, we report a randomized multicenter phase III trial assessing the lot-to-lot consistency of the 2014-2015 Northern Hemisphere quadrivalent split-virion inactivated influenza vaccine (IIV4; Sanofi Pasteur) and comparing its immunogenicity and safety with that of trivalent inactivated influenza vaccine (IIV3) in younger and older adults (EudraCT no. 2014-000785-21). Younger (18-60 y, n = 1114) and older (>60 y, n = 1111) adults were randomized 2:2:2:1:1 to receive a single dose of one of three lots of IIV4, the licensed IIV3 containing the B Yamagata lineage strain, or an investigational IIV3 containing the B Victoria lineage strain. Post-vaccination (day 21) hemagglutination inhibition antibody titers were equivalent for the three IIV4 lots. For the pooled IIV4s vs. IIV3, hemagglutination inhibition antibody titers were also non-inferior for the A strains, non-inferior for the B strain when present in the comparator IIV3, and superior for the B strain lineage when absent from the comparator IIV3. For all vaccine strains, seroprotection rates were ≥98% in younger adults and ≥90% in older adults. IIV4 also increased seroneutralizing antibody titers against all three vaccine strains of influenza. All vaccines were well tolerated, with no safety concerns identified. Solicited injection-site reactions were similar for IIV4 and IIV3 and mostly grade 1 and transient. This study showed that in younger and older adults, IIV4 had a similar safety profile as the licensed IIV3 and that including a second B strain lineage in IIV4 provided superior immunogenicity for the added B strain without affecting the immunogenicity of the three IIV3 strains.

    Abstract Objective The purpose of this study was to evaluate the extended efficacy, safety, and tolerability of escitalopram relative to placebo in adolescents with major depressive disorder (MDD). Methods Adolescents (12–17 years) who completed an 8-week randomized, double-blind, flexible-dose, placebo-controlled, lead-in study of escitalopram 10–20 mg versus placebo could enroll in a 16–24-week, multisite extension trial; patients maintained the same lead-in randomization (escitalopram or placebo) and dosage (escitalopram 10 or 20 mg/day, or placebo) during the extension. The primary efficacy was Children's Depression Rating Scale-Revised (CDRS-R) change from the lead-in study baseline to treatment week 24 (8-week lead-in study plus 16-week extension); the secondary efficacy was Clinical Global Impressions-Improvement (CGI-I) score at week 24. All efficacy analyses used the last observation carried forward (LOCF) approach; sensitivity analyses used observed cases (OC) and mixed-effects model for repeated measures (MMRM). Safety was evaluated via adverse event (AE) reports and the clinician-rated Columbia-Suicide Severity Rating Scale (C-SSRS). Results Following lead-in, 165 patients enrolled in the double-blind extension (82 placebo; 83 escitalopram); 40 (48.8%) placebo and 37 (44.6%) escitalopram patients completed treatment. CDRS-R total score improvement was significantly greater for escitalopram than for placebo (p=0.005, LOCF; p=0.014; MMRM). Response rates (CDRS-R ≥40% reduction from baseline [adjusted and unadjusted] and CGI-I ≤2) were significantly higher for escitalopram than for placebo (LOCF); remission rates (CDRS-R ≤28) were 50.6% for escitalopram and 35.7% for placebo (p=0.002). OC analyses were not significantly different between groups. The most frequent escitalopram AEs (≥5% and more frequent than placebo) were headache, nausea, insomnia, vomiting, influenza-like symptoms, diarrhea, and urinary tract infection. Most AEs were

    The purpose of this study was to compare the efficacy of the treatment of tinnitus with a phase-shifting pure tone to that of the same tone treatment without phase shifting. A double-blind crossover randomized controlled trial. This study was conducted at the University Medical Center Groningen. Twenty-two patients with predominantly tonal tinnitus underwent both intervention and control treatments. Each treatment consisted of three 30-minute sessions in 1 week. The control treatment was identical to the intervention treatment, except that the stimulus was a pure tone without phase shifting. Questionnaires, tinnitus loudness match, and annoyance and loudness ratings were used to measure treatment effects. Pure-tone treatment and phase-shift treatment had no significant effect on tinnitus according to questionnaires (Tinnitus Handicap Index, Tinnitus Reaction Questionnaire, Hospital Anxiety and Depression Scale, and Maastricht Questionnaire), audiological matching procedures, and loudness and annoyance ratings of tinnitus. Furthermore, phase-shift treatment showed no additional significant improvement in comparison with pure-tone treatment. Changes in questionnaire scores due to pure-tone and the phase-shift treatment were correlated. On average across the group, both treatments failed to demonstrate a significant effect. Both treatments were beneficial for some patients. However, a positive effect was not demonstrated that could be attributed to the periodic shifting of the phase of the stimulus tone.

    Full Text Available Background: Macrolides are prescribed in the treatment of pityriasis rosea despite conflicting results of the limited number of studies evaluating their role in its treatment. Aim: A randomized double-blind placebo-controlled trial was conducted to evaluate the effect of azithromycin on the clinical course of pityriasis rosea. Methods: Seventy patients of pityriasis rosea were given either azithromycin (n = 35 or placebo (n = 35 and were followed-up at 2, 4 and 6 weeks. Pruritus was assessed in both groups using the visual analogue scale (VAS . Change in the pityriasis rosea severity score (PRSS and in the VAS were recorded as outcome measures and were compared statistically. Results: The decrease in PRSS from baseline through 2, 4 and 6 weeks within both treatment (P < 0.001 and placebo (P < 0.001 arms was found to be statistically significant; however, this change was not significantly different in the two groups (P = 0.179. Similarly, the decrease in VAS was found to be statistically significant within both groups (P < 0.001; however, the change was comparable between the two groups (P < 0.937. Analysis by Fisher′s exact test did not find a significant difference between the two groups for PRSS and VAS. Conclusion: Azithromycin is not effective in pityriasis rosea and the use of macrolides for this disease should not be encouraged in clinical practice.

    Halitosis (bad breath) is a common condition that is socially crippling for vast parts of the population and results from malodorous volatile sulfur compounds, which are by-products of oral bacteria. In this doubled-blind, randomized study, 75 subjects with halitosis were evaluated. The participants were treated with or without abrasive microcapsules (candy) containing zinc gluconate 0.5%, propolis 2%, and a combination of both (zinc 0.25% and propolis 1%). The halitosis was assessed by a Halimeter, a portable instrument that measures the emission of volatile sulfur compounds at different time exposures to the treatments. Breezy candy (which is sugar-free) was found effective in the treatment of halitosis for up to 4 hours. While treatment with regular candy (group 1, traditional candy without abrasive particles) showed reduction in malodor of 10%, Breezy candy showed reduction of up to 60% in malodor (P halitosis. The combined effect of abrasion by microcapsules with zinc supplement represents a novel and successful approach for the treatment of halitosis.

    Residual symptoms of major depressive disorder are a source of long-term morbidity. New therapeutic strategies are required to alleviate this morbidity and enhance patient quality of life. Citicoline has been used for vascular accidents and has been effective in cognitive rehabilitation. It has been used successfully to reduce craving in patients with substance abuse disorder and for mood management of bipolar disorder. Here, we test citicoline effectiveness as an adjuvant therapy in major depression. A double-blind randomized trial was designed on 50 patients with major depressive disorder who were under treatment with citalopram. Patients were allocated to 2 groups and received citicoline (100 mg twice a day) or placebo as an adjuvant treatment for 6 weeks. Depressive symptoms were assessed by the Hamilton Depression Rating Scale (HDRS) at baseline and at weeks 2, 4, and 6. Significantly greater improvement was observed in the HDRS scores of the citicoline group compared with the placebo group from baseline to weeks 2, 4, and 6 (Ps = 0.030, 0.032, and 0.021, respectively). Repeated-measures general linear model demonstrated a significant effect for time × treatment interaction on the HDRS score (F2.10,101.22 = 3.12, P = 0.04). Remission rate was significantly higher in the citicoline group compared with the placebo group (P = 0.045). Citicoline was an effective adjuvant to citalopram in the therapy of major depressive disorder.

    Background: Irritable bowel syndrome (IBS) is gastrointestinal functional disorder which is multifactorial with unknown etiology. There are several modalities for treatment of it. Acupuncture is increasingly used in numerous diseases, also in gastrointestinal disorders like IBS. The purpose of the study was to assess the effects of catgut embedding acupuncture in improving of IBS. Materials and Methods: A randomized double blind sham control clinical trial was designed. A total of 60 IBS patients assigned to three separated groups. The first group received clofac as drug only group (DO). The second one received catgut embedding acupuncture in special point (AP) and the last group received sham acupuncture (SA). Symptoms, pain, depression and anxiety assessed before and after two weeks at the end of study. Results: There was statistically significant difference between AP and SA and DO in constipation and bloating. Differences that were statistically significant favored acupuncture on pain (F = 6.409, P = 0.003), and depression (F = 6.735, P = 0.002) as the other outcomes. The average (standard deviation (SD)) of weight loss was 2 kg (0.88) in acupuncture group. Conclusion: Our finding showed a significant positive associated between acupuncture and IBS. Catgut embedding acupuncture is a new method which can eliminated IBS symptoms and can use as alternative therapeutic method for improvement of IBS. PMID:25538771

    Treatment of osteoarthritis (OA) is challenging owing to the inefficacy and long-term adverse events of currently available medications including non-steroidal anti-inflammatory drugs. Curcuminoids are polyphenolic phytochemicals with established anti-inflammatory properties and protective effects on chondrocytes. The aim of this study is to investigate the clinical efficacy of curcuminoids in patients suffering from knee OA. A pilot randomized double-blind placebo-control parallel-group clinical trial was conducted among patients with mild-to-moderate knee OA. Patients were assigned to curcuminoids (1500 mg/day in 3 divided doses; n = 19) or matched placebo (n = 21) for 6 weeks. Efficacy measures were changes in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analogue scale (VAS) and Lequesne's pain functional index (LPFI) scores during the study. There was no significant difference in age, gender, body mass index, and VAS, WOMAC and LPFI scores between the study groups at baseline (p > 0.05). Treatment with curcuminoids was associated with significantly greater reductions in WOMAC (p = 0.001), VAS (p  0.05). There was no considerable adverse effect in both groups. To conclude, curcuminoids represent an effective and safe alternative treatment for OA. Copyright © 2014 John Wiley & Sons, Ltd.

    To determine the efficacy of a nonsteroidal anti-inflammatory drug vs. paracetamol in pain relief during medical abortion and to evaluate whether nonsteroidal anti-inflammatory drugs interfere with the action of misoprostol. A prospective double-blind controlled study. University-affiliated tertiary hospital. One hundred twenty women who underwent first-trimester termination of pregnancy. Patients received 600 mg mifepristone orally, followed by 400 microg of oral misoprostol 2 days later. They were randomized to receive ibuprofen or paracetamol when pain relief was necessary. Patients completed a questionnaire about side effects and pain score and returned for an ultrasound follow-up examination 10-14 days after medical abortion. Success rates, as defined by no surgical intervention, and pain scores were assessed. Ibuprofen was found to be statistically significantly more effective for pain relief after medical abortion compared with paracetamol. There was no difference in the failure rate of medical abortion, and the frequency of surgical intervention was slightly higher in the group that received paracetamol (16.3% vs. 8.5%). Ibuprofen was found to be more effective than paracetamol for pain reduction during medical abortion. A history of surgical or medical abortion was predictive for high pain scores. Despite its anti-prostaglandin effects, ibuprofen use did not interfere with the action of misoprostol.

    Full Text Available Abstract Background The Paracetamol (Acetaminophen In Stroke (PAIS study is a phase III multicenter, double blind, randomized, placebo-controlled clinical trial of high-dose acetaminophen in patients with acute stroke. The trial compares treatment with a daily dose of 6 g acetaminophen, started within 12 hours after the onset of symptoms, with matched placebo. The purpose of this study is to assess whether treatment with acetaminophen for 3 days will result in improved functional outcome through a modest reduction in body temperature and prevention of fever. The previously planned statistical analysis based on a dichotomization of the scores on the modified Rankin Scale (mRS may not make the most efficient use of the available baseline information. Therefore, the planned primary analysis of the PAIS study has been changed from fixed dichotomization of the mRS to a sliding dichotomy analysis. Methods Instead of taking a single definition of good outcome for all patients, the definition is tailored to each individual patient's baseline prognosis on entry into the trial. Conclusion The protocol change was initiated because of both advances in statistical approaches and to increase the efficiency of the trial by improving statistical power.

    Mastocytosis is frequently associated with mast cell-mediated symptoms which require relieving medication. While second generation antihistamines (sgAHs) are the first line therapeutic strategy to treat mast cell mediator-related symptoms, controlled clinical trials on how they improve quality of life have not been performed. This randomized, double-blind, placebo-controlled, cross-over trial assessed rupatadine 20 mg daily in the treatment of mastocytosis symptoms in 30 adult patients. Symptoms were assessed by a visual analogue scale (VAS) and symptom specific quality of life questionnaire (ItchyQoL). The mean ItchyQoL total score and VAS symptom score were significantly improved in the rupatadine treatment phase compared with placebo. There were also significant reductions from placebo in the severity of itch, wheal and flare, flushing, tachycardia and headache but not gastrointestinal symptoms. In this first comprehensive trial of a sgAH in mastocytosis, rupatadine 20 mg daily for 4 weeks significantly controlled symptoms and improved patients' quality of life. © 2013 John Wiley & Sons A/S.

    Selective serotonin reuptake inhibitors (SSRIs) are known to induce delayed orgasm and ejaculation. However, different SSRIs may differentially delay ejaculation. A double-blind, fixed-dose study in healthy men with lifelong rapid ejaculation was performed to evaluate potential differences between clinically relevant doses of two selective serotonin reuptake inhibitors, paroxetine and citalopram, in their effects on ejaculation. Thirty men with an intravaginal ejaculation latency time (IELT) less than 1 minute were randomly assigned to receive paroxetine (20 mg/day) and citalopram (20 mg/day) for 5 weeks, after taking half the dosage in the first week. During the 1-month baseline and 6-week treatment period, IELTs were measured at home by using a stopwatch procedure. The trial was completed by 23 men. Analysis of variance revealed a between-group difference in the evolution of IELT delay over time (p = 0.0004); the IELT after paroxetine and citalopram gradually increased from 18 and 21 seconds to approximately 170 and 44 seconds, respectively. Paroxetine 20 mg/day exerted a strong delay (8.9-fold increase), whereas citalopram 20 mg/day mildly delayed ejaculation (1.8-fold increase). These results indicate that paroxetine leads to a significant delay in orgasm and ejaculation, whereas citalopram seems to have less of an effect on it.

    We aimed to evaluate the effects of 5% dapsone gel compared with 0.75% metronidazole gel in the treatment of papulopustular rosacea. In a double-blind randomized clinical trial, 56 adult patients with papulopustular rosacea were enrolled. The severity of disorder was determined by the patient according to visual analogue score (VAS). Investigator's global assessment (IGA) scores and number of inflammatory lesions were recorded. 5% dapsone gel was administered for group D and 0.75% metronidazole gel was administered for group M. Systemic doxycycline was administered for all patients. Follow-up assessments were done at 4, 8, and 12 weeks. Changes in VAS, IGA scores and number of lesions were evaluated. Intention to treat analysis was carried out using SPSS version 17 (Chicago, IL). There was no significant difference in sex and age distribution between the two groups. Mean (SD) IGA score before and after intervention in group D was 3.9 (0.9) and 3.3 (0.9), respectively (PDapsone gel was as effective as metronidazole gel in the treatment of papulopustular rosacea.

    Full Text Available Attention-Deficit/Hyperactivity Disorder is one of the most common mental disorders in childhood, and it continues to adulthood without proper treatment. Stimulants have been used in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD for many years, and the efficacy of methylphenidate in the treatment of adults with ADHD has been proven to be acceptable according to meta-analysis studies. However, there are some concerns about stimulants. Finding other effective medications for the treatment of adult ADHD seems necessary. We hypothesized bupropion could be effective in the treatment of adult ADHD because some theoretical and experimental evidence exists to support efficacy of this medication. Forty-two patients with a diagnosis of ADHD, according to the revised fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, were randomized to receive 150 mg/day bupropion or placebo for a 6-week double-blind, placebo-controlled clinical trial. Each patient filled the Conners' Adult ADHD Rating Scales-Self-Report-Screening version (CAARS before starting to take medication and in weeks 3 and 6 of the study. The mean score of the two groups receiving bupropion or placebo decreased over the 6 weeks. There was a significant difference between the two groups in CAARS score after 6 weeks. Bupropion is more effective than placebo in the treatment of adults with ADHD. Bupropion can be an alternative medication for the treatment of Adults with ADHD as its clinical efficacy was proven by other studies.

    To find out the safe and efficient sedative agent for primary molar pulpectomy in uncooperative pediatric patients. This double blind randomized trial enrolled 40 anxious and healthy 2-6 year olds. All subjects received IV propofol (1-1.5 mg/kg) or ketofol (1-1.5 mg/kg propofol with 0.25 mg/kg ketamine) as per group assignment after oral midazolam premedication (0.5 mg/kg). Sedation maintenance was done with propofol infusion at 25-75 microg/kg/min titrated to a predefined Worse level as per Houpt's sedation rating scale. Additional bolus/es was/were administered in the dosage similar to induction dose in case of inadequate sedation. Primary outcomes were intraoperative and postoperative adverse events. Secondary outcomes were vital signs, success of procedure, operator satisfaction, sedation quality, treatment time, recovery time and total propofol dose. Significantly greater incidence of respiratory depression was reported for ketofol group (11/20; 55%) when compared to propofol group (3/20; 15%) (p = 0.008). Desaturation was the most common adverse respiratory event with significantly greater incidence in ketofol group (9/20; 45%) when compared to propofol only group (3/20; 15%) (p = 0.033). No significant differences regarding secondary outcomes were reported in two groups. Both the regimen exhibited similar sedation profile while propofol alone emerged as a safer option.

    AD, the most prevalent cause of dementia, affects twice as many women as men. Therapeutic options are limited, but results of prior studies support the hypothesis that estrogen treatment may improve symptoms of women with this disorder. Forty-two women with mild-to-moderate dementia due to AD were enrolled into a randomized, double-blind, placebo-controlled, parallel-group trial of unopposed conjugated equine estrogens (1.25 mg/day) for 16 weeks. Outcome data were available for 40 women at 4 weeks and 36 women at 16 weeks. At both 4 and 16 weeks, there were no significant differences or statistical trends between treatment groups on the primary outcome measure (the cognitive subscale of the Alzheimer's Disease Assessment Scale), clinician-rated global impression of change, or caregiver-rated functional status. Exploratory analyses of mood and specific aspects of cognitive performance also failed to demonstrate substantial group differences. Although conclusions are limited by small sample size and the possibility of a type II error, results suggest that short-term estrogen therapy does not improve symptoms of most women with AD. These findings do not address possible long-term effects of estrogen in AD, possible interactions between estrogen and other treatment modalities, or putative effects of estrogen in preventing or delaying onset of this disorder.

    Fibromyalgia syndrome (FMS) is a chronic, generalized and diffuse pain disorder accompanied by other symptoms such as emotional and cognitive deficits. The FMS patients show a high prevalence of gastrointestinal symptoms. Recently it has been found that microbes in the gut may regulate brain processes through the gut-microbiota-brain axis, modulating thus affection, motivation and higher cognitive functions. Therefore, the use of probiotics might be a new treatment that could improve the physical, psychological and cognitive state in FMS; however, no evidence about this issue is available. This paper describes the design and protocol of a double-blind, placebo-controlled and randomized pilot study. We use validated questionnaires, cognitive task through E-Prime and biological measures like urine cortisol and stool fecal samples. The trial aim is to explore the effects of eight weeks of probiotics therapy in physical (pain, impact of the FMS and quality of life), emotional (depression, and anxiety) and cognitive symptoms (attention, memory, and impulsivity) in FMS patients as compared to placebo. This pilot study is the first, to our knowledge, to evaluate the effects of probiotics in FMS. The primary hypothesis was that FMS patients will show a better performance on cognitive tasks, and an improvement in emotional and physical symptoms. These results will contribute to a better understanding in the gut-brain axis. Here we present the design and protocol of the study.

    Full Text Available Background: Irritable bowel syndrome (IBS is gastrointestinal functional disorder which is multifactorial with unknown etiology. There are several modalities for treatment of it. Acupuncture is increasingly used in numerous diseases, also in gastrointestinal disorders like IBS. The purpose of the study was to assess the effects of catgut embedding acupuncture in improving of IBS. Materials and Methods: A randomized double blind sham control clinical trial was designed. A total of 60 IBS patients assigned to three separated groups. The first group received clofac as drug only group (DO. The second one received catgut embedding acupuncture in special point (AP and the last group received sham acupuncture (SA. Symptoms, pain, depression and anxiety assessed before and after two weeks at the end of study. Results: There was statistically significant difference between AP and SA and DO in constipation and bloating. Differences that were statistically significant favored acupuncture on pain (F = 6.409, P = 0.003, and depression (F = 6.735, P = 0.002 as the other outcomes. The average (standard deviation (SD of weight loss was 2 kg (0.88 in acupuncture group. Conclusion: Our finding showed a significant positive associated between acupuncture and IBS. Catgut embedding acupuncture is a new method which can eliminated IBS symptoms and can use as alternative therapeutic method for improvement of IBS.

    Full Text Available Hormone replacement therapy (HRT is frequently prescribed to healthy women to ameliorate menopausal symptoms. HRT is used long term (≥ 1 year to prevent chronic disease in older women. The objective of this study was to review the benefits and risks of HRT and studies of menopause or HRT in Taiwan via a MEDLINE search. Recommendations are provided for future HRT research in Taiwan. Randomized, double-blind, placebo-controlled clinical trials are considered the gold standard of scientific evidence. A MEDLINE literature search (January 1966-July 2002 identified 23 papers on trials (≥ 1 year that met the inclusion criteria. The results showed that various HRT regimens used for more than 1 year caused more harm than good in healthy menopausal women and that there was no benefit for women with coronary artery disease, Alzheimer's disease, hysterectomy, hysterosalpingooophorectomy, and ischemic stroke. None of this research was conducted in Taiwan. A MEDLINE search using the key words “estrogen replacement therapy and menopause in Taiwan” identified 16 studies. There was only one, short-term, HRT trial. No evidence suggested benefits from long-term HRT in menopausal women in Taiwan.

    To evaluate the efficacy of treatment with nefiracetam compared to placebo in poststroke apathy. A parallel group, randomized, placebo-controlled, double-blind two-center trial in patients with recent stroke and apathy was conducted in 2 tertiary teaching hospitals in Perth, Western Australia, between March 2010 and October 2014. Consenting patients hospitalized with stroke were screened for participation at the time of hospitalization and, if diagnosed with apathy 8-36 weeks later, they were randomized to 12 weeks of 900 mg/day nefiracetam or placebo. The primary efficacy parameter was change in apathy at 12 weeks defined by the 14-item Apathy Scale (AS). Of 2514 patients screened, only 377 (15%) were eligible for the study after the first screening, 233 declined further participation, and 144 were assessed for apathy at 8-36 weeks post stroke to confirm eligibility. Twenty patients out of 106 with a complete psychiatric assessment had apathy (19%). Of this sample, 13 patients were randomized. Overall, the AS score decreased by a mean of 7.0 points (95% CI = -14.6 to .6), but there was no significant between-group difference at week 12 (mean paired t-tests, P > .14). Treatment with nefiracetam did not prove to be more efficacious than placebo in ameliorating apathy in stroke. The main limitation was the very small sample randomized, highlighting the limitations of conducting drug trials for behavioral problems among stroke patients. Pharmacological studies of apathy in stroke will require a large multicenter study and a massive sample of patients. Copyright © 2016 National Stroke Association. Published by Elsevier Inc.

    Close to half of women who were smokers prior to conception quit smoking in pregnancy, when endogenous progesterone levels are high. However, at least half resume pre-pregnancy smoking levels within weeks after delivery and when progesterone levels drop. The current pilot study tested the feasibility and preliminary efficacy of postpartum progesterone replacement in preventing relapse to smoking in postpartum women with a history of pre-pregnancy smoking. This was an 8-week, double-blind, parallel, randomized, placebo-controlled pilot trial of 41 women with a history of pre-pregnancy smoking who achieved abstinence by 32 weeks of gestation. Immediately following delivery women were randomized to oral micronized progesterone (200mg twice daily) or placebo via computerized urn randomization program. The main outcome measures were descriptions of study feasibility: recruitment and retention. Secondary outcomes were 7-day point prevalence of abstinence at week 8, time to relapse and smoking cravings. The trial was feasible with adequate randomization, 64% (41/64) of eligible women, and trial retention, 78% (32/41) completed the trial. Women taking progesterone were 1.8 times more likely to be abstinent during week 8 and took longer to relapse (10 vs. 4 weeks) compared to the placebo group, although these differences did not reach statistical significance. After adjusting for age and pre-quit smoking level, the number needed to treat was 7. There was a 10% greater decline per week in craving ratings in the progesterone group compared to placebo (β=-0.10, 95% CI: -0.15, -0.04, p<0.01). No serious adverse events occurred during the trial. These preliminary findings support the promise of progesterone treatment in postpartum smokers and could constitute a therapeutic breakthrough.If these preliminary findings can be evaluated and replicated in a larger study with sufficient power, this may constitute an acceptable and safe smoking relapse prevention strategy for use

    Ethanol lock therapy (ELT) has been shown to reduce the rate of catheter-related bloodstream infection (CRBSI) in high-risk home parenteral nutrition (HPN) patients. The aim of this study was to determine whether ELT therapy for all patients newly started on HPN would reduce the incidence of CRBSI. This study was a prospective, double-blind, randomized controlled trial that was carried out from July 2014 to April 2016. The study participants were patients newly started on HPN, and they were randomly assigned to either treatment with ELT or our current standard of care with saline heparin locks. The primary outcome was occurrence of CRBSI. Thirty eight patients that were newly started on HPN were randomized to either treatment with ELT (n = 18) or to our current standard of care with heparin locks (n = 20). Four patients in the ELT group and one patient in the control arm had a CRBSI (p = 0.17). No significant adverse side effects were noted during the study. This study did not show improvement in the rate of CRBSI with ELT in all patients started on HPN. ELT therapy may be most helpful to reduce in CRBSI in high-risk HPN patients, but further studies with a randomized control trial design of high-risk patients are needed to further clarify this important issue in HPN patients. The study was registered at clinicaltrials.gov prior to patient enrollment (NCT02227329). Copyright © 2017 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

    Full Text Available In this double-blind, randomized clinical trial, 36 healthy male volunteers were randomly distributed into three groups (n=12 that underwent a three-step treatment. For four consecutive days, we alternately administered a standardized dried extract of Equisetum arvense (EADE, 900 mg/day, placebo (corn starch, 900 mg/day, or hydrochlorothiazide (25 mg/day, separated by a 10-day washout period. Each volunteer served as his own control, and the groups’ results were compared. We repeated the same evaluation after each stage of treatment to evaluate the safety of the drug. The diuretic effect of EADE was assessed by monitoring the volunteers’ water balance over a 24 h period. The E. arvense extract produced a diuretic effect that was stronger than that of the negative control and was equivalent to that of hydrochlorothiazide without causing significant changes in the elimination of electrolytes. There was no significant increase in the urinary elimination of catabolites. Rare minor adverse events were reported. The clinical examinations and laboratory tests showed no changes before or after the experiment, suggesting that the drug is safe for acute use. Further research is needed to better clarify the mechanism of diuretic action and the other possible pharmacological actions of this phytomedicine.

    Chronic rhinosinusitis is a common disease which causes persisting inflammatory conditions of one or more sinuses. This study was designed to evaluate the effect of thyme honey nasal spray as an adjunctive medication on chronic rhinosinusitis after functional endoscopic sinus surgery. This was a randomized, placebo controlled, double-blind clinical study. 64 patients with chronic rhinosinusitis undergoing functional endoscopic sinus surgery were enrolled in this study. Patients were randomized and blinded to receive either placebo or thyme honey nasal spray in addition to the standard regimen postoperatively. Patients were visited on postoperative days 7, 30 and 60. The sino-nasal outcome test, endoscopic grading system and sinus CT-scan were scored before operation and on the day 60 after surgery. 54 patients completed the study. Significant improvement was observed in both treatment groups. There were no significant changes in SNOT-22, endoscopy and CT-scan scores between the two study groups. However, a greater reduction in endoscopic scores was shown in thyme honey group. The incidence of adverse effects was not significantly different between the groups, but synechiae formation and epistaxis were lower in treatment group. Thyme honey nasal spray seems to be a low-priced potential adjuvant remedy with excellent safety profile, to reduce inflammation and polyp formation and also fostering mucosal healing for patients suffering from chronic rhinosinusitis. However, further studies are recommended.

    Full Text Available This randomized, double-dummy, double-blind study was to observe the therapeutic effects of compound Danshen dripping pill (CDDP in treating early diabetic retinopathy (DR. All the 57 type 2 diabetes cases in nonproliferative diabetic retinopathy (NPDR stage were divided into two groups randomly: 28 cases treated with CDDP as the treated group and 29 cases treated with calcium dobesilate as the control group. The best corrected visual acuity (BCVA in the treated group was significantly improved after treatment when compared to that before treatment (P<0.05. Mean defect (MD of visual field, hemorrhage area of the fundus, microaneurysm number, fluorescent leakage area, and capillary nonperfusion area evaluated by visual field, fundus photography, and fundus fluorescein angiography in the treated group had the same results as BCVA. However, there was no statistical difference in each index between the two groups. No obvious adverse events with clinical significance occurred. Our present study showed that CDDP has a similar improvement and safety to calcium dobesilate for NPDR. In future DR treatments, CDDP may function as the auxiliary drug.

    To evaluate effects of preoperative high-dose glucocorticoid on the inflammatory response and recovery after endovascular aortic aneurysm repair (EVAR). The postimplantation syndrome after EVAR may delay recovery due to the release of proinflammatory mediators. Glucocorticoids may reduce postoperative inflammatory responses and enhance recovery, but with limited information on EVAR. A single-center, randomized, double-blind, placebo-controlled trial of 153 patients undergoing elective EVAR between November 2009 and January 2013. Patients received 30 mg/kg of methylprednisolone (MP) (n = 77) or placebo (n = 76) preoperatively. Primary outcome was a modified version of the systemic inflammatory response syndrome. Secondary outcome measures were the effect on inflammatory biomarkers, morbidity, and time to meet discharge criteria. Of 153 randomized patients, 150 (98%) were evaluated for the primary outcome. MP reduced systemic inflammatory response syndrome from 92% to 27% (P recovery after EVAR for abdominal aortic aneurysms. Further safety and dose-response studies are required to allow recommendations for general practice. clinicaltrials.gov Identifier: NCT00989729.

    Full Text Available Acute gastroenteritis is one of the most common infectious diseases of childhood. Its symptoms are vomiting, diarrhea, and dehydration. In the emergency ward, intravenous rather than oral rehydration is usually preferred because of the high likelihood of emesis. Treatments to reduce emesis are of value in improving the rehydration procedure. Our study is a double-blind randomized trial and proposes the use of ondansetron as an anti-emetic drug to treat children with acute gastroenteritis. Seventy-four in-patients, aged 3 months to 15 years, were enrolled and randomly assigned to an ondansetron or placebo group. Inclusion criteria were the diagnosis of acute gastroenteritis and the absence of other diseases or allergies to drugs. A single bolus (0.15 mg/kg of ondansetron was injected intravenously; normal 0.9% saline solution was used as a placebo. This treatment induced vomiting cessation in the ondansetron group significantly in comparison to the placebo group. The length of the hospital stay and the oral rehydration fluid volume were similar in the two groups and no adverse effects were noticed. Thus, safety, low cost, and overall bene­fit of ondansetron treatment suggests that this drug can be administered successfully to children with acute gastroenteritis.

    Summary Objective to investigate the efficacy and safety of a medicated plaster containing betamethasone valerate (BMV) 2.25 mg in patients with chronic elbow tendinopathy. Methods randomized, double-blind, placebo-controlled study with assignment 2:2:1:1 to BMV medicated plaster applied daily for 12 hours, daily for 24 hours or matched placebo. 62 patients aged ≥18 years with chronic lateral elbow tendinopathy were randomized. The primary efficacy variable was pain reduction (VAS) at day 28. Secondary objectives included summed pain intensity differences (SPID), overall treatment efficacy and tolerability. Results mean reduction in VAS pain score at day 28 was greater in both BMV medicated plaster groups, −39.35±27.69 mm for BMV12-h and −36.91±32.50 mm for BMV24-h, than with placebo, −20.20±27.32 mm. Considering the adjusted mean decreases, there was a statistically significant difference between BMV12-h and placebo (p=0.0110). Global pain relief (SPID) and overall treatment efficacy were significantly better with BMV. BMV and placebo plasters had similar local tolerability and there were few treatment-related adverse events. Conclusions BMV plaster was significantly more effective than placebo at reducing pain in patients with chronic elbow tendinopathies. The BMV plaster was safe and well tolerated. PMID:27331041

    The efficacy of topical retinoids is well known according to several clinical studies conducted predominantly among Caucasian patients. This study aimed to evaluate the efficacy and safety profile of adapalene and tretinoin among Mexican patients. To compare adapalene 0.1 and 0.3% and tretinoin 0.05% in Mexican subjects with acne vulgaris. We enrolled 171 patients in this single-center, randomized, double-blinded, placebo-controlled clinical trial. The patients applied on the face either adapalene 0.1%, adapalene 0.3%, tretinoin 0.05%, or placebo for 90 days and were evaluated for the reduction in total lesion counts and for the level of irritation. Tretinoin 0.05% and adapalene 0.3% were more effective than adapalene 0.1% and placebo in the reduction of both inflammatory and noninflammatory lesions. Most of adverse events to adapalene and many on tretinoin group were related to skin irritation, dry skin, scaling, pruritus, burning, and postinflammatory hyperpigmentation. Adapalene 0.3% and tretinoin 0.05% are comparable in efficacy, and adapalene 0.1% offers a better safety profile in Mexican patients. © 2013 Wiley Periodicals, Inc.

    Background: Lowering cholesterol is associated with reduced CNS amyloid deposition and increased dietary cholesterol increases amyloid accumulation in animal studies. Epidemiologic data suggest that use of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) may decrease the risk of Alzheimer disease (AD) and a single-site trial suggested possible benefit in cognition with statin treatment in AD, supporting the hypothesis that statin therapy is useful in the treatment of AD. Objective: To determine if the lipid-lowering agent simvastatin slows the progression of symptoms in AD. Methods: This randomized, double-blind, placebo-controlled trial of simvastatin was conducted in individuals with mild to moderate AD and normal lipid levels. Participants were randomly assigned to receive simvastatin, 20 mg/day, for 6 weeks then 40 mg per day for the remainder of 18 months or identical placebo. The primary outcome was the rate of change in the Alzheimer's Disease Assessment Scale–cognitive portion (ADAS-Cog). Secondary outcomes measured clinical global change, cognition, function, and behavior. Results: A total of 406 individuals were randomized: 204 to simvastatin and 202 to placebo. Simvastatin lowered lipid levels but had no effect on change in ADAS-Cog score or the secondary outcome measures. There was no evidence of increased adverse events with simvastatin treatment. Conclusion: Simvastatin had no benefit on the progression of symptoms in individuals with mild to moderate AD despite significant lowering of cholesterol. Classification of evidence: This study provides Class I evidence that simvastatin 40 mg/day does not slow decline on the ADAS-Cog. PMID:21795660

    Full Text Available Abstract Background Diarrhea causes an estimated 2.5 million child deaths in developing countries each year, 35% of which are due to acute diarrhea. Zinc and copper stores in the body are known to be depleted during acute diarrhea. Our objectives were to evaluate the efficacy of zinc and copper supplementation when given with standard treatment to children with acute watery or bloody diarrhea. Methods We conducted a double-blind randomized controlled clinical trial in the Department of Pediatrics at Indira Gandhi Government Medical College Nagpur, India. Eight hundred and eight children aged 6 months to 59 months with acute diarrhea were individually randomized to placebo (Pl, zinc (Zn only, and zinc and copper (Zn+Cu together with standard treatment for acute diarrhea. Results The mean duration of diarrhea from enrolment and the mean stool weight during hospital stay were 63.7 hours and 940 grams, respectively, and there were no significant differences in the adjusted means across treatment groups. Similarly, the adjusted means of the amount of oral rehydration solution or intravenous fluids used, the proportion of participants with diarrhea more than 7 days from onset, and the severity of diarrhea indicated by more than three episodes of some dehydration or any episode of severe dehydration after enrolment, did not differ across the three groups. Conclusion The expected beneficial effects of zinc supplementation for acute diarrhea were not observed. Therapeutic Zn or Zn and Cu supplementation may not have a universal beneficial impact on the duration of acute diarrhea in children. Trial registration The study was registered as an International Standard Randomized Controlled Trial (ISRCTN85071383.

    Episodic cluster headache (ECH) is a primary headache disorder that severely impairs patient's quality of life. First-line therapy in the initiation of a prophylactic treatment is verapamil. Due to its delayed onset of efficacy and the necessary slow titration of dosage for tolerability reasons prednisone is frequently added by clinicians to the initial prophylactic treatment of a cluster episode. This treatment strategy is thought to effectively reduce the number and intensity of cluster attacks in the beginning of a cluster episode (before verapamil is effective). This study will assess the efficacy and safety of oral prednisone as an add-on therapy to verapamil and compare it to a monotherapy with verapamil in the initial prophylactic treatment of a cluster episode. PredCH is a prospective, randomized, double-blind, placebo-controlled trial with parallel study arms. Eligible patients with episodic cluster headache will be randomized to a treatment intervention with prednisone or a placebo arm. The multi-center trial will be conducted in eight German headache clinics that specialize in the treatment of ECH. PredCH is designed to assess whether oral prednisone added to first-line agent verapamil helps reduce the number and intensity of cluster attacks in the beginning of a cluster episode as compared to monotherapy with verapamil.

    GP2015 is a proposed etanercept biosimilar. To demonstrate equivalent efficacy, and comparable safety and immunogenicity of GP2015 and the etanercept originator (ETN, Enbrel(®) ) in patients with moderate-to-severe chronic plaque-type psoriasis. In total, 531 eligible patients were randomized 1 : 1 to self-administer GP2015 or ETN twice weekly subcutaneously. Patients with ≥ 50% improvement in Psoriasis Area and Severity Index (PASI 50) at week 12 were rerandomized to continue the same treatment on a once-weekly dosing schedule or to undergo a sequence of three treatment switches between GP2015 and ETN until week 30. Thereafter, patients continued treatment with the product they had been assigned to last, up to week 52. The difference in PASI 75 (75% improvement from baseline PASI score) response rates at week 12 between GP2015 and ETN (primary end point) was -2·3%. The 95% confidence interval (-9·85 to 5·30) was well contained within the prespecified margin range of -18 to 18. The incidence of treatment-emergent adverse events up to week 52 was comparable between continued GP2015 (59·8%) and ETN (57·3%); switching treatments revealed comparable safety profiles. Antidrug antibodies, all non-neutralizing, were limited to five patients on ETN during treatment period 1, and one patient in the switched ETN group, who had been treated with GP2015 for 12 weeks at the time of the finding. The EGALITY study demonstrated equivalent efficacy and comparable safety and immunogenicity of GP2015 and ETN. The study results provide the final clinical confirmation of biosimilarity and contribute to the totality of the evidence proposing that GP2015 is an etanercept biosimilar. © 2016 The Authors.

    An occlusive patch formulation containing 10% methyl salicylate and 3% l-menthol was recently approved by the US Food and Drug Administration for the treatment of mild to moderate pain. Despite widespread use of counterirritants, including methyl salicylate and menthol, for topical pain relief, published efficacy and safety data regarding the use of the agents alone or in combination are limited. The goal of this study was to determine the efficacy and safety profile of a patch containing 10% methyl salicylate and 3% l-menthol compared with a placebo patch in adult patients with mild to moderate muscle strain. Eligible patients were men or women aged >or=18 years with a clinical diagnosis of mild to moderate muscle strain. Patients were randomly assigned to receive either 1 active patch or 1 placebo patch applied to the skin at the affected area (ie, shoulder, upper back, upper arm, neck, calf, thigh, forearm, abdomen). Pain intensity was assessed on a 100-mm visual analog scale while at rest and with movement for 12 hours after patch application. The primary efficacy end point was the summed pain intensity difference score through 8 hours (SPID8) with movement. Analyses included use of descriptive statistics and an ANOVA model. Safety data, including adverse events, and secondary efficacy end points were also evaluated. A total of 208 patients (104 men, 104 women; age range, 18-78 years) were randomized to 1 of 2 study groups (105 in the active-patch group [mean age, 37.3 years], 103 in the placebo-patch group [mean age, 38.1 years]). The primary efficacy analysis (SPID8 with movement) indicated that patients receiving the active patch experienced significantly greater pain relief (approximately 40%) than those patients receiving a placebo patch (mean [SD], 182.6 [131.2] vs 130.1 [144.1]; P = 0.005). Analysis of the per-protocol population also found significantly more relief (P = 0.024) in the active-patch group (176.2 [131.4]; n = 92) versus the placebo

    We investigated the efficacy and safety of desmopressin add-on therapy for men with persistent nocturia on α-blocker for lower urinary tract symptoms in this placebo controlled study. The study included men 40 to 65 years old with lower urinary tract symptoms and persistent nocturia despite α-blocker therapy for at least 8 weeks. Patients were randomized to once daily placebo or desmopressin 0.2 mg for 8 weeks. The primary end point was to assess changes in the mean number of nocturia episodes from baseline to the final assessment. Other secondary end points and adverse events were evaluated. A total of 86 patients were randomized to treatment, including placebo in 39 and desmopressin 0.2 mg in 47. Baseline characteristics were similar in the 2 groups. The desmopressin add-on group was significantly superior to placebo in terms of the change from baseline in the mean number of nocturia episodes (-1.13 ± 0.92 vs -0.68 ± 0.79, p = 0.034), the changes in nocturnal urine volume (p add-on group was similar to that in the placebo group. Most adverse events were mild. Desmopressin add-on therapy in men 40 to 65 years old with persistent nocturia on α-blocker monotherapy for lower urinary tract symptoms is effective and well tolerated.

    Cysteinyl leukotrienes are implicated in the inflammation of bronchiolitis. Recently, a specific cysteinyl leukotriene receptor antagonist, montelukast (Singulair [MSD, Haarlem, Netherlands]), has been approved for infants in granule sachets. Our goal was to evaluate the effect of montelukast on clinical progress and on cytokines in acute bronchiolitis. This was a randomized, placebo-controlled, double-blind, parallel-group study in 2 medical centers. Fifty-three infants (mean age: 3.8+/-3.5 months) with a first episode of acute bronchiolitis were randomly assigned to receive either 4-mg montelukast sachets or placebo, every day, from hospital admission until discharge. The primary outcome was length of stay, and secondary outcomes included clinical severity score (maximum of 12) and changes in type 1 and 2 cytokine levels (including interleukin4/IFN-gamma ratio as a surrogate for the T-helper 2/T-helper 1 ratio) in nasal lavage. Both groups were comparable at baseline, and cytokine levels correlated positively with disease severity. There were neither differences in length of stay (4.63+/-1.88 [placebo group] vs 4.65+/-1.97 days [montelukast group]) nor in clinical severity score and cytokine levels between the 2 groups. No differences in interleukin 4/IFN-gamma ratio between the 2 groups were seen. There was a slight tendency for infants in the montelukast group to recover more slowly than those in the placebo group (clinical severity score at discharge: 6.1+/-2.4 vs 4.8+/-2.2, respectively). Montelukast did not improve the clinical course in acute bronchiolitis. No significant effect of montelukast on the T-helper 2/T-helper 1 cytokine ratio when given in the early acute phase could be demonstrated.

    Full Text Available Background: We aimed to evaluate the effects of Pimpinella anisum (anise from Apiaceae family on relieving the symptoms of postprandial distress syndrome (PDS in this double-blind randomized clinical trial. Materials and Methods: Totally, 107 patients attending the gastroenterology clinic, aged 18-65 years, diagnosed with PDS according to ROME III criteria and signed a written consent form were enrolled. They were randomized to receive either anise or placebo, blindly, for 4 weeks. Anise group included 47 patients and received anise powders, 3 g after each meal (3 times/day. Control group involved 60 patients and received placebo powders (corn starch, 3 gafter each meal (3 times/day. The severity of Functional dyspepsia (FD symptoms was assessed by FD severity scale. Assessments were done at baseline and by the end of weeks 2, 4 and 12. Mean scores of severity of FD symptoms and the frequency distribution of patients across the study period were compared. Results: The age, sex, body mass index, smoking history, and coffee drinking pattern of the intervention and control groups were not significantly different. Mean (standard deviation total scores of FD severity scale before intervention in the anise and control groups were 10.6 (4.1 and 10.96 (4.1, respectively (P = 0.6.

    To test the effects of pregabalin on the induction of neurogenic claudication. This study was a randomized, double-blind, active placebo-controlled, 2-period, crossover trial. Twenty-nine subjects were randomized to receive pregabalin followed by active placebo (i.e., diphenhydramine) or active placebo followed by pregabalin. Each treatment period lasted 10 days, including a 2-step titration. Periods were separated by a 10-day washout period, including a 3-day taper phase after the first period. The primary outcome variable was the time to first moderate pain symptom (Numeric Rating Scale score ≥4) during a 15-minute treadmill test (Tfirst). Secondary outcome measures included pain intensity at rest, pain intensity at the end of the treadmill test, distance walked, and validated self-report measures of pain and functional limitation including the Roland-Morris Disability Questionnaire, modified Brief Pain Inventory-Short Form, Oswestry Disability Index, and Swiss Spinal Stenosis Questionnaire. No significant difference was found between pregabalin and active placebo for the time to first moderate pain symptom (difference in median Tfirst = -1.08 [95% confidence interval -2.25 to 0.08], p = 0.61). In addition, none of the secondary outcome measures of pain or functional limitation were significantly improved by pregabalin compared with active placebo. Pregabalin was not more effective than active placebo in reducing painful symptoms or functional limitations in patients with neurogenic claudication associated with lumbar spinal stenosis. This study provides Class I evidence that for patients with neurogenic claudication, compared with diphenhydramine, pregabalin does not increase the time to moderate pain during a treadmill test. © 2014 American Academy of Neurology.

    Clozapine remains the only medication indicated for refractory schizophrenia. As new antipsychotic drugs become available, their efficacy compared to clozapine, particularly in moderately ill patients, is of great clinical interest. We compared risperidone, the first of these, to clozapine in partially responsive patients. Further, since participation of patients usually excluded from clinical trials is increasingly important, we broadened inclusion to a wider patient population. We compared clozapine (n = 53) to risperidone (n = 54) in a randomized, double-blind, 29-week trial in schizophrenia patients (diagnosed using DSM-IV) at 3 research outpatient clinics. Randomization was stratified by "narrow" or "broad" inclusion criteria. The study was conducted between December 1995 and October 1999. Time to treatment discontinuation for lack of efficacy and time to 20% improvement in the Brief Psychiatric Rating Scale psychotic symptom cluster were the primary outcome measures. There were no differences in all-cause discontinuation; clozapine-treated participants were significantly less likely to discontinue for lack of efficacy (15%) than risperidone-treated participants (38%) (Wilcoxon χ(2)1 = 6.10, P = .01). Clozapine resulted in significantly more global improvement (F2,839 = 6.07, P risperidone. There was no difference in proportions meeting an a priori criterion of psychosis improvement (risperidone: 57%; clozapine: 71%). Significant adverse effect differences in salivation (F1 = 4.05, P risperidone. Clozapine-treated partially responsive patients were less likely to discontinue treatment for lack of efficacy and improved more globally than those treated with risperidone, although psychotic symptoms did not differ. These findings suggest that clozapine should not be restricted to the most severely ill, treatment-refractory patients; it should be considered as an alternative for patients who have some response to other antipsychotics, but still experience

    Objective Helicobacter pylori is recognized as a major etiological factor in the pathogenesis of gastritis and peptic ulcer disease. H. Pylori eradication has a failure rate of more than 30% in pediatric patients, particularly because of poor compliance, antibiotic resistance and occurrence of side-effects. This study was aimed to determine whether adding the probiotics to a standard anti-H. pylori regimen could minimize the gastrointestinal side-effect prevalence and improve the eradication rate. Methods Double-blind randomized placebo controlled study conducted at Children's Medical Center in Tehran, Iran. Sixty six H. pylori positive children were treated with a triple drug treatment protocol (omeprazole+amoxycillin+furazolidon) and randomly allocated to receive either probiotic or placebo. All patients underwent esophagogastroduodendoscopy. H. pylori infection was diagnosed by either rapid urease test (RUT) or histology. H. pylori status was assessed after 4-8 weeks of the completion of treatment with stool H. pylori antigen test. The side effects of the treatment were determined in each group. Findings Mean age of patients was 9.09 (range 3-14) years, 44 (65.7%) patients were boys (sex ratio 2:1). All 66 patients completed the course of treatment and follow-up. The rate of H. pylori eradication was significantly higher in probiotic group (P=0.04). In probiotic supplemented children there was a lower rate of nausea/vomiting (P=0.02) and diarrhea (P=0.039) during treatment. Conclusion This study showed that probiotics have positive effect on the eradication of H. pylori infection. Adjuvant therapy with probiotic is recommended in order to reduce the frequency of antibiotic induced side-effects during treatment with antibiotics. PMID:23446685

    Having good balance is a facilitating factor in the performance of everyday activities. Good balance is also essential in various sport activities in order to both get results and prevent injury. A common measure of balance is postural sway, which can be measured both antero-posteriorly and medio-laterally. There are several companies marketing wristbands whose intended function is to improve balance, strength and flexibility. Randomized controlled trials have shown that wristbands with holograms have no effect on balance but studies on wristbands with minerals seem to be lacking. The aim of this study was to investigate if the mineral wristband had any effect on postural sway in a group of healthy individuals. Randomized, controlled, double-blind study. The study group consisted of 40 healthy persons. Postural sway was measured antero-posteriorly and medio-laterally on a force plate, to compare: the mineral wristband, a placebo wristband, and without any wristband. The measurements were performed for 30 s, in four situations: with open eyes and closed eyes, standing on a firm surface and on foam. Analyses were made with multilevel technique. The use of wristband with or without minerals did not alter postural sway. Closed eyes and standing on foam both prolonged the dependent measurement, irrespective if it was medio-lateral or antero-posterior. Wearing any wristband (mineral or placebo) gave a small (0.22-0.36 mm/s) but not statistically significant reduction of postural sway compared to not wearing wristband. This study showed no effect on postural sway by using the mineral wristband, compared with a placebo wristband or no wristband. Wearing any wristband at all (mineral or placebo) gave a small but not statistically significant reduction in postural sway, probably caused by sensory input.

    Patients with bipolar disorder have recurrent major depression, residual mood symptoms, and limited treatment options. Building on promising pilot data, the authors conducted a 6-week randomized double-blind placebo-controlled trial to investigate the efficacy of adjunctive bright light therapy at midday for bipolar depression. The aims were to determine remission rate, depression symptom level, and rate of mood polarity switch, as well as to explore sleep quality. The study enrolled depressed adults with bipolar I or II disorder who were receiving stable dosages of antimanic medication (excluding patients with hypomania or mania, mixed symptoms, or rapid cycling). Patients were randomly assigned to treatment with either 7,000-lux bright white light or 50-lux dim red placebo light (N=23 for each group). Symptoms were assessed weekly with the Structured Interview Guide for the Hamilton Depression Scale With Atypical Depression Supplement (SIGH-ADS), the Mania Rating Scale, and the Pittsburgh Sleep Quality Index. Remission was defined as having a SIGH-ADS score of 8 or less. At baseline, both groups had moderate depression and no hypomanic or manic symptoms. Compared with the placebo light group, the group treated with bright white light experienced a significantly higher remission rate (68.2% compared with 22.2%; adjusted odds ratio=12.6) at weeks 4-6 and significantly lower depression scores (9.2 [SD=6.6] compared with 14.9 [SD=9.2]; adjusted β=-5.91) at the endpoint visit. No mood polarity switches were observed. Sleep quality improved in both groups and did not differ significantly between them. The data from this study provide robust evidence that supports the efficacy of midday bright light therapy for bipolar depression.

However, there is very little information as to their role in acute asthma exacerbations. We hypothesized that LTRAs may accelerate lung function recovery when given in an acute exacerbation. Methods A randomized, double blind, placebo-controlled trial was conducted at the Aga Khan University Hospital to assess the efficacy of oral montelukast on patients of 16 years of age and above who were hospitalized with acute asthma exacerbation. The patients were given either montelukast or placebo along with standard therapy throughout the hospital stay for acute asthma. Improvements in lung function and duration of hospital stay were monitored. Results 100 patients were randomized; their mean age was 52 years (SD +/− 18.50). The majority were females (79%) and non-smokers (89%). The mean hospital stay was 3.70 ± 1.93 days with 80% of patients discharged in 3 days. There was no significant difference in clinical symptoms, PEF over the course of hospital stay (p = 0.20 at day 2 and p = 0.47 at day 3) and discharge (p = 0.15), FEV1 at discharge (p = 0.29) or length of hospital stay (p = 0.90) between the two groups. No serious adverse effects were noted during the course of the study. Conclusion Our study suggests that there is no benefit of addition of oral montelukast over conventional treatment in the management of acute asthma attack.

    To determine whether pentoxifylline (PTX) slows the decline of muscle strength and function in ambulatory boys with Duchenne muscular dystrophy (DMD). This was a multicenter, randomized, double-blinded, controlled trial comparing 12 months of daily treatment with PTX or placebo in corticosteroid-treated boys with DMD using a slow-release PTX formulation (~20 mg/kg/day). The primary outcome was the change in mean total quantitative muscle testing (QMT) score. Secondary outcomes included changes in QMT subscales, manual muscle strength, pulmonary function, and timed function tests. Outcomes were compared using Student t tests and a linear mixed-effects model. Adverse events (AEs) were compared using the Fisher exact test. A total of 64 boys with DMD with a mean age of 9.9 ± 2.9 years were randomly assigned to PTX or placebo in 11 participating Cooperative International Neuromuscular Research Group centers. There was no significant difference between PTX and the placebo group in total QMT scores (p = 0.14) or in most of the secondary outcomes after a 12-month treatment. The use of PTX was associated with mild to moderate gastrointestinal or hematologic AEs. The addition of PTX to corticosteroid-treated boys with DMD at a moderate to late ambulatory stage of disease did not improve or halt the deterioration of muscle strength and function over a 12-month study period. This study provides Class I evidence that treatment with PTX does not prevent deterioration in muscle function or strength in corticosteroid-treated boys with DMD.

    Various surgical meshes are used in the repair of inguinal hernia and are associated with numerous complications. Our main objective in this study was to determine whether a biologic hernia matrix is equivalent to polypropylene mesh in an open inguinal hernia repair using the Lichtenstein technique. A prospective, randomized, double-blinded, single-center trial was conducted to evaluate the efficacy of a biologic Inguinal Hernia Matrix (IHM; Cook Medical) compared with polypropylene (PP) mesh using Lichtenstein's inguinal hernia repair in a 3-year outcomes study. Patients were evaluated for recurrence and complications by a blinded surgeon at 2 weeks, 3 months, 6 months, and 1 year post procedure. Patient demographics, including comorbidities and nutrition status, were recorded. Intraoperative information including hernia type and location, procedure time, level of difficulty, degree of surgeon frustration, and surgical experience were collected. One hundred male patients provided informed consent and were randomized into the study in a 1:1 fashion. There were no significant differences in degree of difficulty and level of frustration between the 2 groups. At 1-year follow-up, 3 recurrences were diagnosed in the IHM group as compared with none in the PP group (p = 0.11). Persistent pain trended higher in the PP group (6% vs 4%). All 3 recurrences occurred in the direct inguinal hernia group and were performed by attendings in the first year post training (3 different attendings). No recurrences occurred in patients operated on by more senior surgeons. The IHM hernioplasty compares favorably with PP mesh at 1-year follow-up with similar recurrence rates and complications. Surgeon experience appears to be a major factor affecting successful outcomes. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    Therapeutic nuclear magnetic resonance therapy (MRT) works based on the electromagnetic fields. To investigate efficacy of MRT in knee osteoarthritis (OA). Prospective, randomized, double-blind, placebo controlled trial. Outpatient clinic, university hospital. Patients who had mild to moderate knee OA at a single knee joint and between 30-75-years-old were randomized by blinded chip cards (1:1). The treatment group received ten sessions of one hour daily MRT, controls received placebo MRT. All patients underwent clinical examination at baseline, after 2 weeks, and 12 weeks. Imaging included blindly assessed ultrasonography and magnetic resonance (MR) of the knee. Ninety-seven patients completed the study. Both groups improved significantly but the average change from baseline in outcome parameters was similar in MRT group (on VAS-pain,-2.6; WOMAC-pain, -2.09; WOMAC-stiffness, -1.81; WOMAC-physical, -1.96) compared to placebo after two weeks (VAS-pain,-1.6; WOMAC-pain, -1.91; WOMAC-stiffness, -1.27; WOMAC-physical, -1.54). Also changes were quite similar at the 12th week after the treatment. SF-36 components at 12th week improved but changes were not significant. Imaging arm also failed to show significant differences between groups in terms of cartilage thickness on US and MR scores. No adverse events were recorded. MRT is safe, but not superior to placebo in terms of improvement in clinical or imaging parameters after a 10-day course of treatment in mild to moderate knee OA. The present study does not promote use of a 10-day course of MRT in mild to moderate knee OA.

    The newer atypical antipsychotics seem to be as effective as previous antipsychotics for impulsivity and aggressiveness of patients with borderline personality disorder (BPD). Objective of this assessment was to compare the effectiveness of olanzapine versus haloperidol in BPD. Twenty-eight female inpatients, meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria for BPD, were randomly entered in one of the 2 matching contemporaneous groups for an 8-week parallel double-blind study. This included the random assignment to olanzapine or haloperidol in a 1:1 ratio. Primary outcome measurements were as follows: Brief Psychiatric Rating Scale, Clinical Global Impression-Severity Scale, Buss-Durkee Hostility Inventory. Baselines were created at the beginning of the trial through patient assessments and final assessments at the end of the experiment. Analysis of effect size, calculation of confidence intervals and power analysis were also prepared. All of the patients from within both groups completed the study. Intragroup analysis at the eighth week interval revealed significant positive response by both olanzapine and haloperidol in comparison with the baseline (P < 0.05); however, the between-group analysis showed no significant difference, among the patients, at the end of the experiment. The analysis of specific Brief Psychiatric Rating Scale subscales in both groups revealed considerable and comparable improvements in anxiety, tension, depressive mood, and hostility. The effect size analyzes illustrated remarkable improvements with both groups. There seems to be no significant difference between olanzapine and haloperidol regarding the management of mental and behavioral symptoms of patients with BPD.

    To investigate the long-term effect of oral magnesium supplementation on clinical symptoms, bronchial reactivity, lung function and allergen-induced skin responses in children and adolescents with moderate persistent asthma. A double-blind randomized parallel placebo-controlled study. The patients were recruited from the Pediatric Outpatient Clinic, Division of Pulmonology, Allergy and Immunology, and followed at the Center for Investigation in Pediatrics at State University of Campinas Hospital, Brazil. Thirty-seven out of 72 patients met the study criteria. There were no dropouts. The 37 patients (aged 7-19 years, 19 males) were randomized in two groups: magnesium (n=18, 300 mg/day) and placebo (n=19), during 2 months. Both patient groups received inhaled fluticasone (250 microg twice a day) and salbutamol as needed. The primary outcome was bronchial reactivity evaluated with methacholine challenge test (PC20). After a follow-up of 2 months, the methacholine PC20 for testing bronchial reactivity has augmented significantly in the magnesium group only. The skin responses to recognized antigens have also decreased in patients treated with magnesium. The forced vital capacity (FVC), the forced expiratory volume at first second (FEV1), the forced expiratory flow at 25-75 and the FEV1/FVC ratio were similar in both groups. The magnesium group presented fewer asthma exacerbations and used less salbutamol compared to the placebo group. Oral magnesium supplementation helped to reduce bronchial reactivity to methacholine, to diminish their allergen-induced skin responses and to provide better symptom control in pediatric patients with moderate persistent asthma treated with inhaled fluticasone.

    Insomnia, especially maintenance insomnia, is widely prevalent in epilepsy. Although melatonin is commonly used, limited data address its efficacy. We performed a randomized, double-blind, placebo-controlled, crossover study to identify the effects of melatonin on sleep and seizure control in children with epilepsy. Eleven prepubertal, developmentally normal children aged 6-11 years with epilepsy were randomized by a software algorithm to receive placebo or a 9-mg sustained release (SR) melatonin formulation for four weeks, followed by a one-week washout and a four-week crossover condition. The pharmacy performed blinding; patients, parents, and study staff other than a statistician were blinded. The primary outcomes were sleep onset latency and wakefulness after sleep onset (WASO) measured on polysomnography. The secondary outcomes included seizure frequency, epileptiform spike density per hour of sleep on electroencephalogram (EEG), and reaction time (RT) measures on psychomotor vigilance task (PVT). Statistical tests appropriate for crossover designs were used for the analysis. Data were analyzed from 10 subjects who completed the study. Melatonin decreased sleep latency (mean difference, MD, of 11.4 min and p = 0.02) and WASO (MD of 22 min and p = 0.04) as compared to placebo. No worsening of spike density or seizure frequency was seen. Additionally, slow-wave sleep duration and rapid eye movement (REM) latency were increased with melatonin and REM sleep duration was decreased. These changes were statistically significant. Worsening of headache was noted in one subject with migraine on melatonin. SR melatonin resulted in statistically significant decreases in sleep latency and WASO. No clear effects on seizures were observed, but the study was too small to allow any conclusions to be drawn in this regard. Copyright © 2015 Elsevier B.V. All rights reserved.

    Objective Breath holding spells (BHS) are common paroxysmal non-epileptic events in the pediatric population which are very stressfull despite their harmless nature. There has been no specific treatment found for the spells yet. The aim of this study was to evaluate the efficacy of piracetam (2-oxo-l-pyrrolidine) on these children. Materials & Methods In this randomized double blind clinical trial study, 150 children with severe BHS referred to our pediatric outpatient service were enrolled from August 2011 to July 2012. The patients were randomized into two equal groups. One received 40mg/kg/day piracetam and the other group received placebo, twice daily. Patients were followed monthly for three months. The number of attacks/month before and after treatment were documented. Results Of the enrolled patients, 86 were boys. The mean age of the patients was 17 months (range, 6 to 24 months). In the piracetam group, 1 month after treatment an 81% response to treatment was found. In the placebo group, none of the patients had complete remission and 7% of the cases had partial remission. Overall, control of breath-holding spells was observed in 91% of the patients in the group taking piracetam as compared with 16% in the group taking placebo at the end of the study. There was no significant difference detected between the groups regarding the prevalence of drug side effects. Conclusion A significant difference was detected between piracetam and placebo in prevention and controlling BHS. Piracetam (40mg/kg/day) had a good effect on our patients. PMID:24665274

    Full Text Available Aging can result in major changes in the composition and metabolic activities of bacterial populations in the gastrointestinal system and result in impaired function of the immune system. We assessed the efficacy of prebiotic Darmocare Pre® (Bonusan Besloten Vennootschap (BV, Numansdorp, The Netherlands to evaluate whether the regular intake of this product can improve frailty criteria, functional status and response of the immune system in elderly people affected by the frailty syndrome. The study was a placebo-controlled, randomized, double blind design in sixty older participants aged 65 and over. The prebiotic product was composed of a mixture of inulin plus fructooligosaccharides and was compared with placebo (maltodextrin. Participants were randomized to a parallel group intervention of 13 weeks’ duration with a daily intake of Darmocare Pre® or placebo. Either prebiotic or placebo were administered after breakfast (between 9–10 a.m. dissolved in a glass of water carefully stirred just before drinking. The primary outcome was to study the effect on frailty syndrome. The secondary outcomes were effect on functional and cognitive behavior and sleep quality. Moreover, we evaluated whether prebiotic administration alters blood parameters (haemogram and biochemical analysis. The overall rate of frailty was not significantly modified by Darmocare Pre® administration. Nevertheless, prebiotic administration compared with placebo significantly improved two frailty criteria, e.g., exhaustion and handgrip strength (p < 0.01 and p < 0.05, respectively. No significant effects were observed in functional and cognitive behavior or sleep quality. The use of novel therapeutic approaches influencing the gut microbiota–muscle–brain axis could be considered for treatment of the frailty syndrome.

    Abstract Background: Recalcitrant facial flat warts are caused by human papillomavirus and may persist for years despite treatment. Isotretinoin has demonstrated benefits in the treatment of recalcitrant, genital and common warts, but placebo-controlled trials have not been performed. To determine whether isotretinoin is safe and effective for recalcitrant facial flat warts. Isotretinoin 30 mg/day or placebo was administered to 16 and 15 patients, respectively, in double-blind, randomized fashion for 12 weeks. Cutaneous lesions were assessed and adverse events including serologic and ophthalmologic changes were recorded. It is considered that warts were recalcitrant if the patient was treated for at least 3 years with at least three of the following options: retinoids, 5-fluorouracil, imiquimod and cryotherapy using liquid nitrogen. Each patient in the istotretinoin group showed complete clearance of all flat warts, while none of the patients in the placebo group showed any improvement (p=0.0001). The most frequent adverse event was cheilitis. There were no statistically significant changes in the laboratory findings. The study design does not permit complete blinding of the dermatologist who can easily recognize the adverse effects of isotretinoin. The clinical findings, however, were so dramatic that this would not have impacted the findings. Another limitation of the study is a lack of follow-up to assess for recurrence after the drug was discontinued. Isotretinoin is an effective treatment for recalcitrant flat facial warts with a well-known, manageable safety profile.

    Topical tranexamic acid has been claimed to lighten melasma without serious adverse effects. However, controlled studies assessing the efficacy and safety of topical tranexamic acid (TA) for the treatment of melasma is limited. To assess in a double blind, randomized, prospective study, the efficacy of topical 5% tranexamic acid versus vehicle for treatment of melasma. Twenty-three women with bilateral epidermal melasma enrolled in a split-face trial lasting 12 weeks. Patients blindly applied topical 5% tranexamic acid and its vehicle, to the designated sides of the face twice daily in addition to the assigned sunscreen each morning. Pigmentation and erythema were measured objectively using a mexameter and Melasma Area and Severity Index (MASI), in addition to physician and patient global assessments. Twenty-one patients completed the study. Eighteen out of twenty-three patients (78.2%) showed decrease in the melanin index on either or both sides of the face by the end of 12 weeks compared to baseline. The MASI scores were also significantly reduced on both tested sides. However, lightening of pigmentation induced by TA gel was neither superior nor different (p > 0.05) compared to its vehicle although erythema was significant on the TA-applied site (p < 0.05). Although lightening of pigmentation was obtained, the results were not significant between the two regimens. However, topical TA produced erythema.

    Objective.  The safety and efficacy of intrathecal (IT) ziconotide was studied in a randomized, double-blind, placebo-controlled trial. Materials and Methods.  Patients (169 ziconotide, 86 placebo) with severe chronic nonmalignant pain unresponsive to conventional therapy and a visual analog scale of pain intensity (VASPI score) ≥ 50 mm were treated over a 6-day period in an inpatient hospital setting. Initial starting dose was 0.4 µg/hour and was titrated to analgesia or intolerance (maximum dose 7.0 µg/hour). The starting and maximum doses were reduced to 0.1 µg/hour and 2.4 µg/hour, respectively, due to adverse events (AEs). Results.  The mean percent reduction in VASPI score from baseline was 31.2% and 6.0% for ziconotide- and placebo-treated patients, respectively (p ≤ 0.001). During the initial titration phase, a significantly greater percentage of patients in the ziconotide group compared to the placebo group reported AEs, including abnormal gait, amblyopia, dizziness, nausea, nystagmus, pain, urinary retention, and vomiting. Conclusion.  Ziconotide provided significant analgesia in patients for whom conventional therapy failed. However, there was a considerable incidence of ziconotide-associated AEs due to the rapid titration and high doses administered.

    Full Text Available The blood-red sap of Dragon's blood has been used in folk medicine for fractures, wounds, inflammation, gastrointestinal disorders, rheumatism, blood circulation dysfunctions, and cancer. Existing in vitro and in vivo bioactivity of this herb on different mechanisms of healing shows strong potential of this sap in wound healing. This clinical trial study was designated to evaluate the wound healing effect of Dragon's blood on human wounds. Sixty patients, between the ages of 14–65 years, who were referred to remove their skin tag, were assigned to this double-blind, placebo-controlled, randomized clinical trial and received either Dragon's blood or a placebo cream. They were visited on the 3rd, 5th, 7th, 10th, 14th, and 20th day of the trial to check the process of healing and to measure the wound's surface. At the end of trial, there was a significant difference in the mean duration of wound healing between the two groups (p = 0.0001. The phenolic compounds and the alkaloid taspine, which exist in Dragon's-blood resin, are probably the main reasons for the wound healing property of this plant. Being natural accessible, safe, and affordable makes Dragon's blood cream, a good choice for addition to the wound healing armamentarium. Further studies on wounds with different causes and among larger populations are suggested to ensure the effectiveness and safety of Dragon's blood.

    Full Text Available Background: Sodium valproate (SV has been approved for migraine prophylaxis and its intravenous form is used to treat acute migraine attacks. We compared the efficacy and safety of intravenous SV and subcutaneous Sumatriptan in managing acute migraine attacks. Methods: This double-blind randomized clinical trial divided 90 patients into two groups: one group received 400 mg of intravenous SV and the second group received 6 mg of subcutaneous Sumatriptan. Headache severity before treatment and half an hour, one hour, and two hours after treatment was measured based on the VNRS in the groups. Associated symptoms, i.e., photophobia, phonophobia, nausea, and vomiting, were assayed on admission and 2 hours after treatment. Side effects of the drugs were checked 2 hours after injection. Obtained data from the groups were compared. Results: In both groups, pain decrement at the mentioned time points was significant (P0.05, indicating the similar effect of both drugs on pain improvement. In the SV group, photophobia, phonophobia, nausea, and vomiting were improved significantly, while in the Sumatriptan group, only photophobia and vomiting were decreased significantly, indicating the advantage of SV in improving the associated symptoms. Nausea, vomiting, facial paresthesia, and hypotension were more significantly frequent in the Sumatriptan group than in the SV group (P<0.05. Conclusion: Intravenous SV (400 mg was as effective as subcutaneous Sumatriptan in the treatment of acute migraine attacks, but with more improvement in associated symptoms and with fewer side effects.

    Chronic urticaria is one of the most common and disturbing cutaneous condition. The treatment of chronic idiopathic urticaria (CIU) is still a challenge. Antihistamines are recommended as first-line treatment. Rupatadine is a new potent nonsedative anti-H1. To study rupatadine efficacy and safety for moderate to severe CIU treatment. This randomized, double-blind, placebo-controlled, parallel-group, multicentre, study was designed to assess primarily mean pruritus score (MPS) reduction with rupatadine, 10 and 20 mg, administered once daily for 4 weeks. Three hundred and thirty-three patients with active episodes of moderate-to-severe CIU were included. A 57.5% (P rupatadine, respectively, compared with placebo (44.9%). Both doses of rupatadine were not significantly different at any time point, with respect to their effects on pruritus severity, number of wheals and total symptoms scores. Rupatadine 10 mg had an overall better adverse event profile. Rupatadine 10 mg is a fast, long-acting, efficacious and safe treatment option for the management of patients with moderate-to-severe CIU.

    Caspofungin is an antifungal agent of the novel echinocandin class. We investigated its efficacy, safety, and tolerability as therapy for oropharyngeal and/or esophageal candidiasis in a phase II dose-ranging study. Patients were randomized in a double-blind manner to receive either caspofungin acetate (35, 50, or 70 mg) or amphotericin B (0.5 mg/kg of body weight) intravenously once daily for 7 to 14 days. A favorable response required both complete resolution of symptoms and quantifiable improvement of mucosal lesions 3 to 4 days after discontinuation of study drug. Efficacy was assessed using a modified intent-to-treat analysis. No hypothesis testing of efficacy was planned or performed. Of 140 enrolled patients, 63% had esophageal involvement and 98% were infected with the human immunodeficiency virus (HIV) (median CD4 count, 30/mm3). A modestly higher proportion of patients in each of the caspofungin groups (74 to 91%) achieved favorable responses compared to amphotericin B recipients (63%), but there was considerable overlap in the 95% confidence intervals surrounding these point estimates. Similar trends were found in the subgroups with esophageal involvement, a history of fluconazole failure, and CD4 counts of ≤50/mm3. A smaller proportion of patients receiving any dose of caspofungin experienced drug-related adverse events compared to patients given standard doses of conventional amphotericin B (P esophageal candidiasis in this study.

    2013-01-01

    BACKGROUND Latrepirdine is an orally administered experimental small molecule that was initially developed as an antihistamine and subsequently was shown to stabilize mitochondrial membranes and function, which might be impaired in Huntington disease. OBJECTIVE To determine the effect of latrepirdine on cognition and global function in patients with mild to moderate Huntington disease. DESIGN Randomized, double-blind, placebo-controlled study. SETTING Sixty-four research centers in Australia, Europe, and North America. PATIENTS Four hundred three patients with mild to moderate Huntington disease and baseline cognitive impairment (Mini-Mental State Examination score, 10-26). INTERVENTION Latrepirdine (20 mg) vs matching placebo administered orally 3 times daily for 26 weeks. MAIN OUTCOME MEASURES The co-primary outcome measures were cognition as measured by the change in Mini-Mental State Examination score from baseline to week 26 and global function at week 26 as measured by the Clinician Interview-Based Impression of Change, plus carer interview, which ranges from 1 (marked improvement) to 7 (marked worsening). Secondary efficacy outcome measures included behavior, daily function, motor function, and safety. RESULTS The mean change in Mini-Mental State Examination score among participants randomized to latrepirdine (1.5-point improvement) did not differ significantly from that among participants randomized to placebo (1.3-point improvement) (P=.39). Similarly, the distribution of the Clinician Interview-Based Impression of Change, plus carer interview did not differ significantly among those randomized to latrepirdine compared with placebo (P=.84). No significant treatment effects were detected on the secondary efficacy outcome measures. The incidence of adverse events was similar between those randomized to latrepirdine (68.5%) and placebo (68.0%).

    Full Text Available Abstract Background Serum phosphorus control is critical for chronic kidney disease (CKD 5D patients. Currently, clinical profile for an oral phosphorus binder in the mainland Chinese population is not available. Objective To establish the efficacy, safety, and tolerability of lanthanum carbonate in CKD 5D patients. Design Multicenter, randomized, double blind, placebo-controlled study. A central randomization center used computer generated tables to allocate treatments. Setting Twelve tertiary teaching hospitals and medical university affiliated hospitals in mainland China. Participants Overall, 258 hemodialysis or continuous ambulatory peritoneal dialysis (CAPD adult patients were enrolled. Intervention After a 0–3-week washout period and a 4-week lanthanum carbonate dose-titration period, 230 patients were randomized 1:1 to receive lanthanum carbonate (1500 mg-3000 mg or placebo for a further 4-week maintenance phase. Main outcome measures Efficacy and safety of lanthanum carbonate to achieve and maintain target serum phosphorus concentrations were assessed. Results In the titration phase, serum phosphorus concentrations of all patients decreased significantly. About three-fifths achieved target levels without significantly disturbing serum calcium levels. At the end of the maintenance period, the mean difference in serum phosphorus was significantly different between the lanthanum carbonate and placebo-treated groups (0.63±0.62 mmol/L vs. 0.15±0.52 mmol/L, P Conclusion Lanthanum carbonate is an efficacious and well-tolerated oral phosphate binder with a mild AE profile in hemodialysis and CAPD patients. This agent may provide an alternative for the treatment of hyperphosphatemia in CKD 5D patients in mainland China. Trial registration No. ChiCTR-TRC-10000817

    Niacinamide inhibits intestinal sodium/phosphorus transporters and reduces serum phosphorus in open-label studies. A prospective, randomized, double-blind, placebo-controlled crossover trial was performed for assessment of the safety and efficacy of niacinamide. Hemodialysis patients with phosphorus levels > or =5.0 mg/dl were randomly assigned to 8 wk of niacinamide or placebo, titrated from 500 to 1500 mg/d. After a 2-wk washout period, patients switched to 8 wk of the alternative therapy. Vitamin D analogs and calcimimetics were held constant; phosphorus binders were not changed unless safety criteria were met. Thirty-three patients successfully completed the trial. Serum phosphorus fell significantly from 6.26 to 5.47 mg/dl with niacinamide but not with placebo (5.85 to 5.98 mg/dl). A concurrent fall in calcium-phosphorus product was seen with niacinamide, whereas serum calcium, intact parathyroid hormone, uric acid, platelet, triglyceride, LDL, and total cholesterol levels remained stable in both arms. Serum HDL levels rose with niacinamide (50 to 61 mg/dl but not with placebo. Adverse effects were similar between both groups. Among patients who were > or =80% compliant, results were similar, although the decrease in serum phosphorus with niacinamide was more pronounced (6.45 to 5.28 mg/dl) and the increase in HDL approached significance (49 to 58 mg/dl). In hemodialysis patients, niacinamide effectively reduces serum phosphorus when co-administered with binders and results in a potentially advantageous increase in HDL cholesterol. Further study in larger randomized trials and other chronic kidney disease populations is indicated.

    We sought to determine the safety and preliminary efficacy of transcatheter intramyocardial administration of myoblasts in patients with heart failure (HF). MARVEL is a randomized placebo-controlled trial of image-guided, catheter-based intramyocardial injection of placebo or myoblasts (400 or 800 million) in patients with class II to IV HF and ejection fraction stopping the study for financial reasons. At 6 months, similar numbers of events occurred in each group: 8 (placebo), 7 (low dose), and 8 (high dose), without deaths. Ventricular tachycardia responsive to amiodarone was more frequent in myoblast-treated patients: 1 (placebo), 3 (low dose), and 4 (high dose). A trend toward improvement in functional capacity was noted in myoblast-treated groups (Δ6-minute walk test of -3.6 vs +95.6 vs +85.5 m [placebo vs low dose vs high dose; P = .50]) without significant changes in Minnesota Living With HF scores. In HF patients with chronic postinfarction cardiomyopathy, transcatheter administration of myoblasts in doses of 400 to 800 million cells is feasible and may lead to important clinical benefits. Ventricular tachycardia may be provoked by myoblast injection but appears to be a transient and treatable problem. A large-scale outcome trial of myoblast administration in HF patients with postinfarction cardiomyopathy is feasible and warranted. Copyright © 2011 Mosby, Inc. All rights reserved.

    Umeclidinium is a new, long-acting, muscarinic receptor antagonist currently in development for the treatment of chronic obstructive pulmonary disease (COPD). In vitro cell culture data suggest that up to 99 % of umeclidinium is potentially metabolized by cytochrome P450 2D6 (CYP2D6), but without a definitive human metabolism radiolabel study, the extrapolation of in vitro to in vivo is only an estimate. The objective of this study was to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of umeclidinium in patients with normal and deficient CYP2D6 metabolism. This was a randomized, placebo-controlled study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of inhaled single and repeat doses (for 7 days) of umeclidinium. The study took place at a single clinical site, at which subjects remained throughout the study. Healthy volunteers (HVTs) who were normal CYP2D6 metabolizers (HVT-NMs) [n = 20] and poor CYP2D6 metabolizers (HVT-PMs) [n = 16] participated in the study. The subjects received umeclidinium (100-1,000 μg) and placebo as single and repeat doses. The primary outcome measurements were protocol-defined safety and tolerability endpoints. Thirteen subjects in each population reported adverse events (AEs); none were considered serious. No clinically significant abnormalities in vital signs, lung function, haematology, biochemistry, 12-lead electrocardiograms (ECGs) or 24-h Holter ECGs were attributable to the study drug. There were no differences in plasma and urine pharmacokinetics between populations: the plasma area under the concentration-time curve over the dosing interval (from 0 to 24 h for the once-daily drug) [AUC(τ) (ng·h/mL)] and the maximum plasma concentration [C(max) (ng/mL)] ratios (with 90 % confidence intervals [CIs]) following repeat dosing with 500 μg umeclidinium for HVT-PMs (as compared with HVT-NMs) were 1.03 (0.79-1.34) and 0.80 (0.59-1.08), respectively; the cumulative amount of the

    Primary adhesive capsulitis (AC), or frozen shoulder, is an insidious and idiopathic disease. Severe pain is predominant in the first two of the three stages of the condition, which can last up to 21 months. Sixty volunteers with primary AC were randomly assigned to acupuncture with press tack needles compared with press tack placebos in a patient- and observer-blinded placebo-controlled study. The participants were subsequently offered classical needle acupuncture in an open follow-up clinical application. Thirty-four volunteers received conservative therapy, including 10 classical needle acupuncture treatments over 10 weeks, 13 volunteers received conservative therapy without classical needle acupuncture. All subjects agreed to follow-up after one year. Acupuncture treatment was performed using a specific distal needling concept, using reflex areas on distant extremities avoiding local treatment. An immediate improvement of 3.3 ± 3.2 points in Constant-Murley Shoulder Score (CMS) pain subscore was seen in the press tack needles group and of 1.6 ± 2.8 points in the press tack placebos group (P acupuncture significantly improved the pain subscore within 14.9 ± 15.9 weeks compared with 30.9 ± 15.8 weeks with only conservative therapy (P efficiency of distal needling acupuncture on immediate pain reduction was demonstrated in patients with AC and confirmed the applicability of press tack needles and press tack placebos for double-blind studies in acupuncture. Subsequent clinical application observation proved that results obtained with press tack needles/press tack placebos can be transferred to classical needle acupuncture. Integrating acupuncture with conservative therapy showed superior effectiveness with respect to the time course of the recovery process in AC compared with conservative therapy alone.

    Insomnia increases in frequency as women approach and pass through menopause. Studies have not shown acupuncture efficacy for insomnia in postmenopausal women. The aim of this study was to evaluate the effectiveness of acupuncture therapy on sleep parameters, depression symptoms and quality of life in postmenopausal women with insomnia. This study included 18 postmenopausal women aged 50-67 years old. Participants had a body mass index ≤ 30 kg/m(2), presented a diagnosis of insomnia according to the DSM-IV criteria, had experienced at least 1 year of amenorrhea and had a follicle stimulating hormone level ≥ 30 mIU/ml. Participants were not using antidepressants, hypnotics or hormonal therapy. This study was randomized, double-blind and placebo-controlled. The sample was divided into two groups: acupuncture and 'sham' acupuncture. We performed ten sessions of acupuncture and 'sham' acupuncture during a period of 5 weeks. A polysomnography exam (PSG) and questionnaires (WHOQOL-BREF, Beck Depression Inventory and Pittsburgh Sleep Quality Index) were completed by all patients before and after the treatment period. Anthropometric, polysomnographic, and questionnaire data were similar among the groups at baseline. Comparison of baseline and post-treatment data of the acupuncture group showed that treatment resulted in significantly lower scores on the Pittsburgh Questionnaire and an improvement in psychological WHOQOL. The acupuncture group had a higher percentage of the N3 + 4 stage than the sham group in PSG findings. Acupuncture was effective in improving reported sleep quality and quality of life in postmenopausal women with insomnia.

    Full Text Available Background: One of the most common complaints after coronary artery bypass graft (CABG is post-operative pain. Gabapentin is an anticonvulsant and antineuralgic agent. Objective: To evaluate the analgesic effect of preemptive gabapentin on post-operative pain and morphine consumption after cardiac surgery. Methods: A double-blind randomized clinical trial was conducted on 60 male candidates for CABG. The patients were divided into two groups—the gabapentin (n=30 and the control group (n=30. The test group received 800 mg gabapentin orally two hours before the surgery followed by 400 mg of the drug two hours post-extubation. The control group received placebo instead. Then severity of pain was recorded according to an 11-point visual analog pain scale. The amount of morphine consumed, its side effects and hemodynamic changes were also recorded during and at 2, 6, 12, 18 and 24 hours after extubation. Results: The mean±SD cumulative morphine consumption at the first 24 hours after extubation in gabapentin group was 0.9±1.5 mg while it was 1.5±4 mg for the control group. Therefore, gabapentin group consumed 38% less than the control group (P=0.01. The pain scores during rest and coughing at 2, 6, and 12 hours after extubation were also significantly lower in the gabapentin group compared with the control group (P=0.02. The mean±SD mechanical ventilation time was 5.4±1.7 hours for gabapentin group and 1.6±4.4 hours for the control group (P=0.035. The other variables including hemodynamic changes (HR, SBP and DBP, and incidence of nausea, vomiting and respiratory depression showed no significant difference between the studied groups within 24 hours after extubation. Conclusion: Oral pre-medication with gabapentin before CABG significantly reduces post-operative pain and morphine consumption in adult cardiac surgery.

    Full Text Available Background. Diabetic foot ulcers are one disabling complication of diabetes mellitus. Pirfenidone (PFD is a potent modulator of extracellular matrix. Modified diallyl disulfide oxide (M-DDO is an antimicrobial and antiseptic agent. Aim. To evaluate efficacy of topical PFD + M-DDO in a randomized, double-blind trial versus ketanserin in the treatment of noninfected chronic DFU. Methods. Patients received PFD + M-DDO or ketanserin for 6 months. Relative ulcer volume (RUV was measured every month; biopsies were taken at baseline and months 1 and 2 for histopathology and gene expression analysis for COL-1α, COL-4, KGF, VEGF, ACTA2 (α-SMA, elastin, fibronectin, TGF-β1, TGF-β3, HIF-1α, and HIF-1β. Results. Reduction of median RUV in the PFD + M-DDO group was 62%, 89.8%, and 99.7% at months 1–3 and 100% from months 4 to 6. Ketanserin reduced RUV in 38.4%, 56%, 60.8%, 94%, 94.8%, and 100% from the first to the sixth month, respectively. Healing score improved 4.5 points with PFD + M-DDO and 1.5 points with ketanserin compared to basal value. Histology analysis revealed few inflammatory cells and organized/ordered collagen fiber bundles in PFD + M-DDO. Expression of most genes was increased with PFD + M-DDO; 43.8% of ulcers were resolved using PFD + M-DDO and 23.5% with ketanserin. Conclusion. PFD + M-DDO was more effective than ketanserin in RUV reduction.

    Full Text Available Introduction. Extradural anesthesia is a successfull procedure in many operations.This is also a suitable and elective anesthetic procedure in many operations have particular hemodynamic conditions. Hence the onset time on this of anesthesia is slow and the degree of sensory and motor block is relatively variable in many cases, this procedure is not accepted by anesthesiologists and surgeons. So, inspite of its priority in many cases, it is less used. Thegoal of this study is to achieve a practical and effective solution to shorten the onset of analgesia and increasing analgesic duration which studies adding ketamin to bupivacain in extradural anesthesia. Methods. This study is a double blinded randomized clinical trial. Forty adult patients in class 1 and 2 of ASA who have been candidate for elective lower limb or lower abdominal surgery in Al-zahra and Kashani medical center in 1998 were selected. Without receiving any premedications, all of the patients received 500 CC ringer lactated solution before onset of anesthesia and they were divided into 2 groups. Group 1 received 20 cc of 0.5 percent bupivacain+0.5cc of 0.9 percent normal saline. Group 2 (interventional received 20 cc of 0.5 percent bupivacain + 0.5 cc of Ketamin (25mg. The onset of sensory block and the duration of sensory and motor block were measured and compared in both groups. Results. The onset of sensory block in interventional group was shorter than in controlled group. The duration of sensory block in interventional group was longer than in controlled group. The duration of the motor block was longer in controlled group than interventional group (P < 0.05. Discussion. Adding ketamin to bupivacain results in earlier onset and longer duration of analgesia in extradural anesthesia. This effect may be due to the inhibitory effect of the ketamin on posterior nerve root activity in spinal cord which can be an effective mechanism of ketamin in making analgesia.

    It remains unclear whether analgesia from intraperitoneal local anesthetics is via local or central mechanisms. This double-blind clinical trial tests the hypothesis that intraperitoneal local anesthetic is superior to continuous IV infusion for pain management. Primary outcome was morphine consumption during 0 to 24 h. Informed consent was obtained from 60 patients, age 30 to 75 yr, American Society of Anesthesiologists physical status I to II, undergoing abdominal hysterectomy. A computer-generated program randomized patients in parallel arms to group IV: continuous infusion of lidocaine 50 mg/h (10 ml) IV and saline 10 ml/h intermittently intraperitoneal; group IP: injection of lidocaine 50 mg/h (10 ml) once every hour intraperitoneally and continuous infusion of saline 10 ml/h intravenously; and group P (placebo): saline 10 ml/h both intravenously and intermittent intraperitoneal injection. Postoperative morphine consumption, pain intensity, recovery, home discharge, and lidocaine concentrations were measured. Morphine consumption during 0 to 24 h was lower in group IP versus group IV, mean difference -22.6 mg (95% CI, 11.4 to 33.8; P lidocaine in group IP was significantly lower than group IV, 0 to 4.5 h postoperatively (P = 0.03) with no evidence of systemic toxicity. Pain intensity and other recovery parameters were similar between the groups. The lower supplemental morphine consumption and plasma lidocaine concentration in group IP would confirm that the effects of local anesthetics are likely to be predominant via local intraperitoneal receptors or anti-inflammatory effects and not via central mechanisms alone.

    In this double-blind crossover study, the effects of bolus infusions of 0.9% saline (NaCl) and Hartmann's solution on serum albumin, haematocrit and serum and urinary biochemistry were compared in healthy subjects. Nine young adult male volunteers received 2-litre intravenous infusions of 0.9% saline and Hartmann's solution on separate occasions, in random order, each over 1 h. Body weight, haematocrit and serum biochemistry were measured pre-infusion and at 1 h intervals for 6 h. Biochemical analysis was performed on pooled post-infusion urine. Blood and plasma volume expansion, estimated by dilutional effects on haematocrit and serum albumin, were greater and more sustained after saline than after Hartmann's solution (P Hartmann's solution. Subjects voided more urine (median: 1,000 compared with 450 ml) of higher sodium content (median: 122 compared with 73 mmol) after Hartmann's than after saline (both P =0.049), despite the greater sodium content of the latter. The time to first micturition was less after Hartmann's than after saline (median: 70 compared with 185 min; P =0.008). There were no significant differences between the effects of the two solutions on serum sodium, potassium, urea or osmolality. After saline, all subjects developed hyperchloraemia (>105 mmol/l), which was sustained for >6 h, while serum chloride concentrations remained normal after Hartmann's (P Hartmann's solution, due possibly to the more physiological [Na(+)]/[Cl(-)] ratio in Hartmann's solution (1.18:1) than in saline (1:1) and to the hyperchloraemia caused by saline.

    Tonsillectomy, with or without adenoidectomy, is one of the most common surgical procedures in pediatric otolaryngology. Pain is the main cause of morbidity in the postoperative period, where it is serious in some cases, leading to odynophagia and resultant complications such as dehydration. We evaluated the effect of topical clindamycin in the reduction of oropharyngeal pain in children who underwent adenotonsillectomy. Secondary outcomes were otalgia, analgesic use, oral bacterial count, type of diet, secondary bleeding, vomiting, fever, and weight loss. Double-blind, randomized clinical trial. Tertiary hospital. Eighty-two children of both sexes between four and 12 years of age who underwent adenotonsillectomy were allocated to receive topical clindamycin or placebo in the immediate preoperative, intraoperative, and eight-to-12-hours postoperative periods. Pain was measured using a faces pain scale for five days. Reduction of oropharyngeal pain was significant with the use of clindamycin only on the first postoperative day (95% confidence interval, 2.22 to 4.41 [clindamycin] vs 4.53 to 6.3 [placebo]; P = .002). No difference was observed in the aerobic and anaerobic counts by tongue swab between premedication and third-postoperative-day samplings. There were no differences with respect to reduction in otalgia, paracetamol use, return to normal diet, variation in weight, secondary hemorrhage, vomiting, and fever. The use of topical clindamycin was beneficial in reducing pain on the first postoperative day, without effect on subsequent days. Future investigations could examine the use of topical clindamycin not only in the first 12 hours but also during five days of follow-up.

    Tonsillectomy, with or without adenoidectomy, is one of the most common surgical procedures in pediatric otolaryngology. Despite its relative simplicity, pain is the main cause of morbidity in the postoperative period. We determined the effect of topical sucralfate on reduction of oropharyngeal pain in children submitted to adenotonsillectomy. Secondary outcomes were otalgia, analgesic use, type of diet, secondary bleeding, vomiting, fever, and weight loss. Double-blind, randomized clinical trial. Tertiary hospital. Eighty-two children of both sexes between four and 12 years old submitted to adenotonsillectomy were evaluated. They were allocated to receive topical sucralfate or placebo in intraoperative and postoperative periods four times a day for five days. Pain was measured through faces pain scale. Reduction in oropharyngeal pain was significant with use of sucralfate during five days of evaluation (mean, 95% confidence interval, and P value); day 1: 2.05, 1.53-2.58, P = 0.000; day 2: 2.1, 1.51-2.70, P = 0.001; day 3: 1.44, 0.88-1.99, P = 0.003; day 4: 1.13, 0.58-1.55, P = 0.027; day 5: 0.67, 0.26-1.04, P = 0.021). There was no difference in secondary outcomes. We found beneficial effect of use of sucralfate in reduction of oropharyngeal pain in the postoperative period of adenotonsillectomy. However, topical sucralfate does not have a potent effect to the point of being utilized as a single analgesic treatment. Because it is simple, safe, tolerated, and low-cost, it is an important tool as adjuvant treatment of post-tonsillectomy pain.

    Full Text Available Abstract Background Epidemiological studies suggest that smokeless tobacco in the form of Swedish snus has been used by many smokers in Scandinavia to quit smoking, but the efficacy of snus has so far not been evaluated in controlled clinical trials. Methods We conducted a randomized, double-blind, placebo-controlled, clinical trial aimed at assessing the efficacy of snus to help adult cigarette smokers in Serbia to substantially reduce, and, eventually, completely stop smoking. The study enrolled 319 healthy smokers aged 20-65 years at two occupational health centers in Belgrade, Serbia. Most of them (81% expressed an interest to quit rather than just reduce their smoking. Study products were used ad libitum throughout the 48-week study period. The main study objective during the first 24 weeks was smoking reduction. The primary end-point was defined as a biologically verified reduction of ≥ 50% in the average number of smoked cigarettes per day during week 21-24 compared to baseline. During week 25-48 participants were actively instructed to stop smoking completely. Outcome measures of biologically verified, complete smoking cessation included 1-week point prevalence rates at clinical visits after 12, 24, 36, and 48 weeks, as well as 4-, 12- and 24-week continued cessation rates at the week 36 and 48 visits. Results At the week 24 visit, the proportion of participants who achieved the protocol definition of a ≥ 50% smoking reduction was similar in the two treatment groups. However, the proportion that reported more extreme reductions (≥ 75% was statistically significantly higher in the snus group than in the placebo group (p Conclusions Swedish snus could promote smoking cessation among smokers in Serbia, that is, in a cultural setting without traditional use of oral, smokeless tobacco.

    The treatment of infants with bronchiolitis is largely supportive. The role of bronchodilators is controversial. Most studies of the use of bronchodilators have enrolled small numbers of subjects and have examined only short-term outcomes, such as clinical scores. We conducted a randomized, double-blind, controlled trial comparing nebulized single-isomer epinephrine with placebo in 194 infants admitted to four hospitals in Queens-land, Australia, with a clinical diagnosis of bronchiolitis. Three 4-ml doses of 1 percent nebulized epinephrine or three 4-ml doses of normal saline were administered at four-hour intervals after hospital admission. Observations were made at admission and just before, 30 minutes after, and 60 minutes after each dose. The primary outcome measures were the length of the hospital stay and the time until the infant was ready for discharge. The secondary outcome measures were the degree of change in the respiratory rate, the heart rate, and the respiratory-effort score and the time that supplemental oxygen was required. There were no significant overall differences between the groups in the length of the hospital stay (P=0.16) or the time until the infant was ready for discharge (P=0.86). Among infants who required supplemental oxygen and intravenous fluids, the time until the infant was ready for discharge was significantly longer in the epinephrine group than in the placebo group (P=0.02). The need for supplemental oxygen at admission had the greatest influence on the score for severity of illness and strongly predicted the length of the hospital stay and the time until the infant was ready for discharge (Pepinephrine (P=0.02 to Pnebulized epinephrine did not significantly reduce the length of the hospital stay or the time until the infant was ready for discharge among infants admitted to the hospital with bronchiolitis.

    Does octreotide reduce vomiting in cancer-associated bowel obstruction? To evaluate the net effect of adding octreotide or placebo to standardized therapies on the number of days free of vomiting for populations presenting with vomiting and inoperable bowel obstruction secondary to cancer or its treatment. Twelve services enrolled people with advanced cancer presenting with vomiting secondary to bowel obstruction where surgery or anti-cancer therapies were not indicated immediately. In a double-blind study, participants were randomized to placebo or octreotide (600 μg/24 hours by infusion). Both arms received standardized supportive therapy (infusion of ranitidine [200 mg/24 hours], dexamethasone [8 mg/24 hours], and parenteral hydration [10-20 mL/kg/24 hours]). The primary outcome was patient-reported days free of vomiting at 72 hours. In a study that recruited to the numbers identified in its power calculation, 87 participants provided data at 72 hours (45, octreotide arm). Seventeen people (octreotide) and 14 (placebo) were free of vomiting for 72 hours (P = 0.67). Mean days free of vomiting were 1.87 (SD 1.10; octreotide) and 1.69 (SD 1.15; placebo; P = 0.47). An adjusted multivariate regression of the incidence of vomiting over the study showed a reduced number of episodes of vomiting in the octreotide group (incidence rate ratio = 0.40; 95% CI: 0.19-0.86; P = 0.019); however, people in the octreotide arm were 2.02 times more likely to be administered hyoscine butylbromide (P = 0.004), potentially reflecting increased colicky pain. Although there was no reduction in the number of days free of vomiting, the multivariate analysis suggests that further study of somatostatin analogues in this setting is warranted.

    This trial aimed to compare postoperative analgesia, opioid consumption, duration of ileus and hospital stay, and cytokine levels in patients undergoing laparoscopic cholecystectomies who received intravenous lidocaine in comparison with a control group. Prospective, longitudinal, double-blind, and randomized study. Operating room and postoperative recovery area. Forty-four American Society of Anesthesiologists I and II patients older than 17 years, undergoing laparoscopic cholecystectomy, under general anesthesia. The first group received intravenous lidocaine during the procedure until 1 hour postoperatively, whereas the second group received saline. Both groups received dipyrone and morphine patient-controlled analgesia. Pain was assessed by Visual Numeric Scale at rest and when coughing at different times after the end of the surgery. Blood samples were taken at the end of procedure and 24 hours later. The total morphine patient-controlled analgesia demand, the time for the first flatus, and the length of hospital stay were also recorded. Groups were similar in relation to sex (P= .2), age (P= .5), weight (P= .08), and length of surgery (P= .6). No differences were observed regarding the intensity of postoperative pain between the groups, either at rest (P= .76) or when coughing (P= .31), in morphine consumption (P= .9), and in the duration of ileus (P= .5) or length of hospital stay (P= .9). The inflammatory markers interleukin (IL)-1 (P= .02), IL-6 (Plidocaine group against the placebo group, except IL-10 (P= .01), that, because of its anti-inflammatory effects, increased its concentration. Intravenous lidocaine was not able to reduce postoperative pain, opioid consumption, and duration of ileus or length of hospital stay. However, its anti-inflammatory effect was noticeable.

    Full Text Available Abstract Background Studies of the efficacy of vitamin C treatment for fatigue have yielded inconsistent results. One of the reasons for this inconsistency could be the difference in delivery routes. Therefore, we planned a clinical trial with intravenous vitamin C administration. Methods We evaluated the effect of intravenous vitamin C on fatigue in office workers. A group of 141 healthy volunteers, aged 20 to 49 years participated in this randomized, double-blind, controlled clinical trial. The trial group received 10 grams of vitamin C with normal saline intravenously, while the placebo group received normal saline only. Since vitamin C is a well-known antioxidant, oxidative stress was measured. Fatigue score, oxidative stress, and plasma vitamin C levels were measured before intervention, and again two hours and one day after intervention. Adverse events were monitored. Results The fatigue scores measured at two hours after intervention and one day after intervention were significantly different between the two groups (p = 0.004; fatigue scores decreased in the vitamin C group after two hours and remained lower for one day. Trial also led to higher plasma vitamin C levels and lower oxidative stress compared to the placebo group (p Conclusion Thus, intravenous vitamin C reduced fatigue at two hours, and the effect persisted for one day. There were no significant differences in adverse events between two groups. High dose intravenous vitamin C proved to be safe and effective against fatigue in this study.

    Poststroke fatigue is common and reduces quality of life. Current evidence for intervention is limited, and this is the first placebo-controlled trial to investigate treatment of poststroke fatigue with the wakefulness promoting drug modafinil. The trial was randomized, double-blinded, and placebo-controlled. Patients were treated with 400-mg modafinil or placebo for 90 days. Assessments were done at inclusion, 30, 90, and 180 days. The primary end point was fatigue at 90 days measured by the Multidimensional Fatigue Inventory-20 general fatigue domain. Secondary end points included the Fatigue Severity Scale, the Montreal Cognitive Assessment, the modified Rankin Scale and the Stroke-specific quality of Life questionnaire. Adult patients with a recent stroke achieving a score of ≥12 on the Multidimensional Fatigue Inventory-20 general fatigue domain were consecutively included. Exclusion criteria were severe cognitive disabilities and contraindications for modafinil treatment. One thousand one hundred twenty-one patients with stroke were screened and 41 patients included, 21 received modafinil. The primary end point, the Multidimensional Fatigue Inventory-20 general fatigue score, did not differ between groups. Patients in the modafinil group obtained better scores on the Fatigue Severity Scale (P=0.02) and in some subscales of the stroke-specific quality of life questionnaire (0.001

    Full Text Available Abstract Background Tourette Syndrome (TS is a neurological condition presenting chronic motor and phonic tics, and important degree of comorbidity. Considered an uncommon illness, it first becomes apparent during childhood. Current standard treatment only achieves partial control of the condition, and provokes frequent, and sometimes severe, side effects. Methods and design Main aim: To show that, with respect to placebo treatment, the combination of 0.5 mEq/Kg magnesium and 2 mg/Kg vitamin B6 reduces motor and phonic tics and incapacity in cases of exacerbated TS among children aged 7–14 years, as measured on the Yale Global Tic Severity Scale (YGTSS. Secondary aims: Assess the safety of the treatment. Describe metabolic changes revealed by PET. Measure the impact of the experimental treatment on family life. Methodology Randomized, blinded clinical trials. Phase IV study (new proposal for treatment with magnesium and vitamin B6. Scope: children in the geographic area of the study group. Recruitment of subjects: to include patients diagnosed with TS, in accordance with DSM-IV criteria (307.23, during a period of exacerbation, and provided none of the exclusion criteria are met. Instrumentation: clinical data and the YGTSS score will be obtained at the outset of a period of exacerbation (t0. The examinations will be made after 15 (t1, 30 (t2, 60 (t3 and 90 days (t4. PET will be performed at the t0 and t4. We evaluated decrease in the overall score (t0, t1, t2, t3, t4, PET variations, and impact made by the treatment on the patient's life (Psychological General Well-Being Index. Discussion Few clinical trials have been carried out on children with TS, but they are necessary, as current treatment possibilities are insufficient and often provoke side effects. The difficulty of dealing with an uncommon illness makes designing such a study all the more complicated. The present study seeks to overcome possible methodological problems by

    To assess the efficacy and safety of vildagliptin as add-on therapy in Japanese patients with type 2 diabetes mellitus (T2DM), inadequately controlled on stable long-acting, intermediate-acting, or pre-mixed insulin, with or without concomitant metformin. In this 12-week placebo-controlled study, patients were randomized to receive either vildagliptin 50 mg twice daily (bid) or placebo treatment in a 1:1 ratio. The primary endpoint was change in glycated hemoglobin A1c (HbA1c) from baseline to 12-week endpoint. Secondary endpoints included proportion of patients achieving pre-defined HbA1c targets of ≤6.5%, <7.0%, and HbA1c <7.0% in patients with baseline HbA1c ≤8.0% and change in fasting plasma glucose (FPG) after 12 weeks of treatment. Regular monitoring was performed to record any treatment-emergent adverse events (AEs) and serious adverse events or hypoglycemic episodes. Of the 156 patients randomized, 96.8% completed the study (vildagliptin, n = 76; placebo, n = 75). Patient demographics and clinical characteristics were comparable between the groups at baseline. Addition of vildagliptin resulted in statistically significant reductions in HbA1c after 12 weeks (-1.01 ± 0.06%), with a between-treatment difference of -0.91 ± 0.09% (p < 0.001). FPG levels reduced from baseline to 12 weeks in the vildagliptin group (-1.2 ± 0.2 mmol/L), with a between-treatment difference of -1.2 ± 0.3 mmol/L which was significant (p < 0.001). The proportion of patients achieving HbA1c targets was higher with vildagliptin treatment for all pre-defined responder rate categories. The overall incidence of AEs was comparable between groups (vildagliptin, 46.2% vs. placebo, 43.6%). The overall incidence of hypoglycemic events was low and all events were self-treatable without using drug therapy. No severe hypoglycemic events were reported. Treatment with vildagliptin 50 mg bid as add-on to insulin with or without metformin resulted in statistically

    DA-1229 is a novel, potent and selective dipeptidyl peptidase-4 (DPP-IV) inhibitor that is orally bioavailable. We aimed to evaluate the optimal dose, efficacy and safety of DA-1229, in Korean subjects with type 2 diabetes mellitus suboptimally controlled with diet and exercise. We enrolled 158 patients (mean age, 53 years and a mean BMI, 25.6 kg/m(2) ). The mean baseline fasting plasma glucose level, HbA1c and duration of diabetes were 8.28 mmol/L, 7.6% (60 mmol/mol) and 3.9 years, respectively. After 2 or 6 weeks of an exercise and diet program followed by 2 weeks of a placebo period, the subjects were randomized into one of four groups for a 12-week active treatment period: placebo, 2.5, 5 or 10 mg of DA-1229. All three doses of DA-1229 significantly reduced HbA1c from baseline compared to the placebo group (-0.09 in the placebo group vs. -0.56, -0.66 and -0.61% in 2.5, 5 and 10-mg groups, respectively) but without any significant differences between the doses. Insulin secretory function, as assessed by homeostasis model assessment β-cell, the insulinogenic index, 2-h oral glucose tolerance test (OGTT) C-peptide and post-OGTT C-peptide area under the curve (AUC)0-2h, significantly improved with DA-1229 treatment. The incidence of adverse events was similar between the treatment groups and DA-1229 did not affect body weight or induce hypoglycaemic events. DA-1229 monotherapy (5 mg for 12 weeks) improved HbA1c, fasting plasma glucose level, OGTT results and β-cell function. This drug was well tolerated in Korean subjects with type 2 diabetes mellitus. © 2014 The Authors. Diabetes/Metabolism Research and Reviews published by John Wiley & Sons, Ltd.

    Food allergen-specific sublingual immunotherapy (FA-SLIT) has emerged as a novel and successful approach for desensitizing human patients to specific food allergens. It has not been tested in dogs. To investigate the efficacy, quality of life (QoL), tolerability and safety of FA-SLIT in dogs with adverse food reactions (AFR). Dogs with proven AFR were randomized to treatment (T group; n = 7) or placebo (P group; n = 6) to receive either FA-SLIT (based on the results of a food elimination trial) or glycerinated saline, respectively. The treatment was continued daily for 6 months with fortnightly dosage escalations. To evaluate the treatment, pruritus Visual Analog Scale (pVAS), Canine Atopic Dermatitis Extent and Severity Index (CADESI-04), QoL, faecal consistency scores, owner assessment, overall tolerability scores and blood analyses were assessed. Eleven dogs completed the study, two dogs in the T group were withdrawn by the owner after FA-SLIT exacerbated clinical signs of AFR. Statistical tests showed significant protection against food challenge induced clinical signs following FA-SLIT therapy, as indicated by reduced pVAS and CADESI scores (P < 0.05). The QoL did not differ between groups. The treatment was rated as effective or quite effective by 80% of the owners, whereas placebo was rated as ineffective by all owners. FA-SLIT was effective, well tolerated and safe. No severe adverse events were recorded; erythema and pruritus were reported in association with only 0.7% of the dispensed doses. Larger clinical trials with more extended maintenance immunotherapy periods will be needed to provide more precise estimates of efficacy and frequency of adverse events. © 2016 ESVD and ACVD.

    This proof-of-concept, pilot study aimed to explore the safety and anti-sialorrhea efficacy of single doses of intra-oral slow dissolving thin films containing tropicamide (NH004) or placebo. Nineteen non-demented, idiopathic stable or fluctuating PD patients who complained of sialorrhea received 3 doses (0.3, 1, 3mg) of tropicamide and placebo in random order, separated by 7 days. A 10-cm visual analog scale (VAS) was used to measure the patient's subjective feelings of saliva levels at baseline and at 15, 30, 45, 90 and 120 min after treatment administration. For the last 7 patients, saliva volume was measured at baseline and 75 min after treatment. Fluctuating patients were evaluated in the ON-condition. The mean age of included patients was 67±12 years, 78% were male. Median disease duration was 8 years. The mean decrease in VAS score from baseline to 120 min were -0.55±0.54, -1.08±0.54, -1.53±0.52 and -0.81±0.51 for placebo and 0.3, 1 and 3mg tropicamide, respectively (F=0.6 p=0.6, ANOVA). Tropicamide 1mg resulted in a significant VAS score decrease (95%CI: -2.57 to -0.48). Saliva volume was reduced by 27%, 33% or 20% after tropicamide 0.3, 1 or 3mg vs 5% with placebo (p=0.5, Friedman). No adverse events were detected in any of the treatment sequences. Results of this pilot, proof-of-concept study show that NH004 was safe and exerted antisialorrhea effects worthy of further exploration. Copyright © 2011 Elsevier B.V. All rights reserved.

    To assess whether the dietary supplement (bromelain) has the potential to reduce plasma fibrinogen and other cardiovascular disease (CVD) risk factors in patients with diabetes. This randomized placebo controlled, double blind, parallel design, efficacy study was carried out in China and investigated the effect of 12 weeks of bromelain (1,050 mg/day) on plasma fibrinogen. This randomized controlled trial (RCT) recruited 68 Chinese diabetic patients [32 males and 36 females; Han origin, mean age of 61.26 years (standard deviation (SD), 12.62 years)] with at least one CVD risk factor. Patients were randomized into either bromelain or placebo group. While bromelain group received bromelain capsule, the placebo group received placebo capsule which consisted inert ingredient and has no treatment effect. Subjects were required to take 1,050 mg (3×350 mg) of either bromelain or starch-filled placebo capsules, two to be taken (2×350 mg) after breakfast and another (350 mg) after dinner, daily for 12 weeks. Plasma fibrinogen, CVD risk factors and anthropometric indicators were determined at baseline and at 12 weeks. The change in the fibrinogen level in the bromelain group at the end of the study showed a mean reduction of 0.13 g/L (standard deviation (SD) 0.86g/L) compared with the mean reduction of 0.36 g/L (SD 0.96 g/L) for the placebo group. However, there was no significant difference in the mean change in fibrinogen between the placebo and bromelain groups (mean difference=0.23g/L (SD 0.22 g/L), =0.291). Similarly, the difference in mean change in other CVD risk factors (blood lipids, blood pressure), blood glucose, C-reactive protein and anthropometric measures between the bromelain and placebo groups was also not statistically significant. Statistical differences in fibrinogen between bromelain and placebo groups before the trial despite randomization may have influenced the results of this study. This RCT failed to show a beneficial effect in reducing fibrinogen

    The objective of this study was to evaluate the efficacy and tolerability of blonanserin for the treatment of Korean patients with schizophrenia using a double-blind risperidone-compared design. Patients aged 18 to 65 years with schizophrenia were randomly assigned to blonanserin or risperidone treatment for 8 weeks. The efficacy was assessed using the mean change in Positive and Negative Syndrome Scale score total scores from baseline to week 8. Safety assessments included monitoring of vital signs, a physical examination, laboratory tests, and adverse events. Of 206 randomly enrolled patients, 103 receiving blonanserin and 103 receiving risperidone were included in the analysis. In this study, noninferiority between blonanserin and risperidone was demonstrated. The mean change in the Positive and Negative Syndrome Scale total score at the final evaluation time point was -23.48 +/- 19.73 for the blonanserin group and -25.40 +/- 18.38 for the risperidone group. Adverse events, which occurred less frequently in the blonanserin than in the risperidone group, included dysarthria (P = 0.0288), dizziness (P = 0.0139), increased alanine aminotransferase and aspartate aminotransferase (P = 0.0095 and P = 0.0032, respectively), and increased level blood prolactin (P = 0.0012). On the other hand, the adverse events that occurred more frequently in the blonanserin than in the risperidone group was hand tremor (P = 0.0006). Blonanserin was effective in the treatment of Korean patients with schizophrenia compared with risperidone and was more tolerable with a better safety profile, particularly with respect to prolactin elevation. These findings suggest that blonanserin is useful in the treatment of schizophrenia.

    To compare the safety and efficacy of bupropion with methylphenidate in children and adolescents with attention-deficit/hyperactivity disorder (ADHD). In a 6-week randomized double-blind study, 44 patients with a DSM-IV-TR diagnosis of ADHD were randomly assigned to receive bupropion 100-150 mg/day (100 mg/day for 30 kg) or methylphenidate 20-30 mg/day. Symptoms were assessed using Teacher and Parent Attention-Deficit/Hyperactivity Disorder Rating Scale-IV (ADHD-RS-IV) at baseline and weeks 3 and 6. Forty patients had at least one post-baseline measurement, and 38 patients completed the trial. No significant difference was found between the two groups on the Parent and Teacher ADHD-RS-IV scores ([F(1, 38) = 0.266, p = 0.609] and [F(1, 38) = 0.001, p = 0.972], respectively). By week 6, 18 patients (90%) in each group achieved response on the Parent scale (Fisher's exact test p-value = 1.0). With the Teacher ADHD-RS-IV used, eight (40%) patients in the bupropion group and 12 (60%) patients in the methylphenidate group achieved response by week 6 (χ(2) (1) = 1.600, p = 0.206). Headache was observed more frequently in the methylphenidate group. Frequency of other side effects was not significantly different between the two groups. Bupropion has a comparable safety and efficacy profile with methylphenidate in children and adolescents with ADHD. Copyright © 2012 John Wiley & Sons, Ltd.

    The efficacy and safety of a new centrally acting antitussive agent, isoaminile citrate, was compared with that of chlophedianol hydrochloride in a double-blind, randomized interpatient study. A total of 66 patients participated, two and four patients were lost to follow-up with isoaminile and chlophedianol, respectively. In the experimentally induced cough in 12 normal human subjects, isoaminile (40 mg) was as effective as chlophedianol (20 mg), but its duration of action was somewhat longer. One subject developed allergic skin rash with chlophedianol and was withdrawn from the study. In 60 patients with cough associated with chest diseases, isoaminile (40 mg, 3 x daily) was as effective as chlophedianol (20 mg, 3 x daily) in suppressing cough as judged from the 3-h and 24-h cough counts. The increase in PEFR at day 7 of treatment was somewhat more marked with chlophedianol as compared with isoaminile. None of the drugs interfered with the expectoration process. The side effects observed were few, mild in nature, and did not require a decrease in dose or withdrawal of treatment in any of the patients. Isoaminile citrate was concluded to be an effective and relatively safe antitussive agent. Isoaminile citrate, alpha(isopropyl)-alpha-(beta-dimethylaminoproyl) phenylacetonitrile citrate, is a centrally acting antitussive agent. In animal experiments this drug was as efficacious as codeine but was devoid of any respiratory depressant effect [Krause 1958, Kuroda et al. 1971]. This controlled double-randomized interpatient study was designed to test the comparative efficacy and safety of isoaminile and chlophedianol, another centrally acting antitussive, in humans.

    In patients with severe preeclampsia there is an increased risk of postpartum hemorrhage, but the hemodynamic changes associated with severe preeclampsia make the management of any kind of bleeding particularly troublesome. There are many pharmacological options for the management of postpartum hemorrhage, oxytocin being the first line of treatment. There is as yet no evidence about the safety and efficacy of using carbetocin, an oxytocin agonist, in these patients. We aimed to compare oxytocin with carbetocin for the routine prevention of postpartum hemorrhage in patients with severe preeclampsia. We performed a prospective double-blind randomized controlled trial in 60 women with severe preeclampsia, recruited between July and September 2010. The women were randomized to receive either oxytocin or carbetocin during the third stage of labour. The primary outcome measure was postpartum hemorrhage requiring additional uterotonics, and the secondary outcome measures were the difference in hemoglobin levels between groups, the development of oliguria, and hemodynamic status (mean arterial pressure and heart rate) after administration of the drug. Carbetocin was as effective as oxytocin in the prevention of postpartum hemorrhage in women with severe preeclampsia. Carbetocin had a safety profile similar to that of oxytocin, and it was not associated with the development of oliguria or hypertension in this cohort. Carbetocin is an appropriate alternative to oxytocin for the prevention of postpartum hemorrhage in women with severe preeclampsia. Considering that it appears not to have a major hemodynamic effect in women with severe preeclampsia and that it uses a lower volume per dose than oxytocin, it should be considered a valid option in the management of the third stage of labour in women with hypertensive disorders of pregnancy.

    This study aimed to determine the safety and tolerability of trofinetide and to evaluate efficacy measures in adolescent and adult females with Rett syndrome, a serious and debilitating neurodevelopmental condition for which no therapies are available for its core features. This was an exploratory, phase 2, multicenter, double-blind, placebo-controlled, dose-escalation study of the safety and tolerability of trofinetide in 56 adolescent and adult females with Rett syndrome. Subjects were randomly assigned in a 2:1 ratio to 35 mg/kg twice daily of trofinetide or placebo for 14 days; 35 mg/kg twice daily or placebo for 28 days; or 70 mg/kg twice daily or placebo for 28 days. Safety assessments included adverse events, clinical laboratory tests, vital signs, electrocardiograms, physical examinations, and concomitant medications. Efficacy measurements were categorized into four efficacy domains, which related to clinically relevant, phenotypic dimensions of impairment associated with Rett syndrome. Both 35 mg/kg and 70 mg/kg dose levels of trofinetide were well tolerated and generally safe. Trofinetide at 70 mg/kg demonstrated efficacy compared with placebo based on prespecified criteria. Trofinetide was well tolerated in adolescent and adult females with Rett syndrome. Although this study had a relatively short duration in a small number of subjects with an advanced stage of disease, consistent efficacy trends at the higher dose were observed in several outcome measures that assess important dimensions of Rett syndrome. These results represented clinically meaningful improvement from the perspective of the clinicians as well as the caregivers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Voice-aligned compression (VAC) is a method used in Oticon's hearing aids to provide more comfortable hearing without sacrificing speech discrimination. The complex, non-linear compression curve for the VAC strategy is designed based on the frequency profile of certain spoken Western languages. We hypothesized that hearing aids could be further customized for Japanese-speaking users by modifying the compression curve using the frequency profile of spoken Japanese. A double-blind randomized controlled crossover study was performed to determine whether or not Oticon's modified amplification strategy (VAC-J) provides subjectively preferable hearing aids for Japanese-speaking hearing aid users compared to the same company's original amplification strategy (VAC). The participants were randomized to two groups. The VAC-first group received a pair of hearing aids programmed using the VAC strategy and wore them for three weeks, and then received a pair of hearing aids programmed using VAC-J strategy and wore them for three weeks. The VAC-J-first group underwent the same study, but they received hearing aids in the reverse sequence. A Speech, Spatial and Qualities (SSQ) questionnaire was administered before beginning to use the hearing aids, at the end of using the first pair of hearing aids, and at the end of using the second pair of hearing aids. Twenty-five participants that met the inclusion/exclusion criteria from January 1 to October 31, 2016, were randomized to two groups. Twenty-two participants completed the study. There were no statistically significant differences in the increment of SSQ scores between the participants when using the VAC- or the VAC-J-programmed hearing aids. However, participants preferred the VAC-J strategy to the VAC strategy at the end of the study, and this difference was statistically significant. Japanese-speaking hearing aid users preferred using hearing aids that were fitted with the VAC-J strategy. Our results show that the VAC strategy

    Botulinum toxin injection has been applied for pain relief in various chronic pain syndromes. Recently, systematic review studies reported inconclusive effects of Botulinum toxin in myofascial pain management. The present study aimed to demonstrate the efficacy and safety of Botulinum toxin type A (BTxA) (Botox®) injection for pain reduction in myofascial trigger point (MTrP) of the upper trapezius muscle. Thirty-three patients with 48 MTrP on the upper trapezius muscles over three months with moderate to severe pain intensity diagnosed at physical medicine and rehabilitation outpatient department were recruited between December 2011 and March 2012. Eligible patients were blinded and randomly injected with single 0.2 ml (20 IU) of BTxA for 24 MTrP and 0.2 ml of 0.9% NaCl solution for 24 MTrP at the most tender trigger point on the upper trapezius muscle. All patients were advised for stretching exercise and ergonomic adaptation throughout the study. At 3- and 6-week after injections, visual analogue scale (VAS), the pressure pain threshold (PPT), and reported adverse effects were measured. Both BTxA and control groups demonstrated statistically significant differences in VAS reduction and increased PPT after 3 weeks and 6 weeks compared with before treatment. There were no statistically significant differences in VAS reduction from baseline between the two groups at 3- and 6-week after treatment. A statistically significant difference in improvement of PPT from baseline and 6-week after BTxA injection compared with 0.9% NaCl group was shown (1.0 ± 0.9 and 0.5 ± 0.7, p = 0.036). There was mild degree side-effects that spontaneous resolved within one week in both groups without significant difference in percentage. No severe adverse effects were reported during the study. The efficacy in VAS reduction of a single 20 IU of Botulinum toxin type A (Botox®) injection was not different from 0.9% NaCl for myofascial trigger point at the upper trapezius muscle. However

    As a Chinese Traditional Medicine product, Kuntai capsule could improve the peri-menopausal symptoms in postmenopausal women. But it is still not clear whether Kuntai capsule has a good effect on alleviating peri-menopausal symptoms induced by gonadotropin releasing hormone agonist (GnRH-a) treatment. The purpose of this study was to investigate the clinical effectiveness and safety of Kuntai capsule, on peri-menopausal symptoms in endometriosis (EMS) patients, with postoperative GnRH-a treatment. Ninety EMS ovarian cyst women with postoperative GnRH-a administration were enrolled in the study, and were randomly divided into Kuntai group, Tibolone group, or blank Control group. The therapeutic strategy in Kuntai group was 4 Kuntai capsules tid,po for 12 weeks after the first GnRH-a injection, while Tibolone 2.5 mg qd, po for 12 weeks in Tibolone group. There was no drug addition in Control group. Climacteric complaints were evaluated by Kupperman menopausal index (KMI) and hot flash/sweating score. Liver and renal functions, lipid profile, serum sex hormone levels and endometrial thickness were measured, and the frequency of adverse events in Kuntai and Tibolone groups was recorded. (1) Before GnRH-a therapy, the baseline parameter results were comparable in the three groups (P > 0.05). (2) After GnRH-a therapy, KMI and hot flash/sweating scores in all the three groups increased significantly (P KMI and hot flash/sweating score results were as follows: Control group > Kuntai group > Tibolone group (P KMI and hot flash/sweating score in Control group were significantly higher than the other two groups (P 0.05). (3) No statistical change took place in the liver and renal functions and lipid profile in all the three groups after the treatment (P > 0.05). (4) The posttherapeutic serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) level and endometrial thickness decreased significantly in all the three groups (P < 0.05).

    Psychophysiological hallmarks of posttraumatic stress disorder (PTSD) include exaggerated fear responses, impaired inhibition and extinction of conditioned fear, and decreased discrimination between safety and fear cues. This increased fear load associated with PTSD can be a barrier to effective therapy thus indicating the need for new treatments to reduce fear expression in people with PTSD. One potential biological target for reducing fear expression in PTSD is the hypothalamic-pituitary-adrenal (HPA) axis, which is dysregulated in PTSD. Recent translational rodent studies and cross-sectional clinical studies have shown that dexamethasone administration and the resulting suppression of cortisol in individuals with PTSD leads to a decrease in the fear responses characteristic of PTSD. These data, taken together, suggest that dexamethasone may serve as a novel pharmacologic intervention for heightened fear responses in PTSD. We conducted a double-blind, placebo-controlled trial to test our hypothesis that dexamethasone administration and the concomitant suppression of HPA axis hyperactivity would attenuate fear expression and enhance fear extinction in individuals with PTSD. Study participants (n=62) were recruited from Grady Memorial Hospital in Atlanta, GA. Participants were randomized to receive dexamethasone or placebo prior to fear conditioning and extinction, in a counterbalanced design (treatments separated by a week). Both PTSD- (n=37) and PTSD+ (n=25) participants showed significant startle increases in the presence of the danger signal during placebo and dexamethasone treatments (all p<0.05). However, only PTSD- control participants showed decreases in fear-potentiated startle across extinction blocks during both conditions (p's≤0.001), with PTSD+ participants showing deficits in fear extinction and safety discrimination in the placebo condition. Notably, extinction and discrimination deficits in PTSD+ subjects were markedly reversed with dexamethasone

    Thrombin is a critical element of crosstalk between pathways contributing to worsening of established heart failure (HF). The aim of this study is to explore the efficacy and safety of rivaroxaban 2.5 mg bid compared with placebo (with standard care) after an exacerbation of HF in patients with reduced ejection fraction (HF-rEF) and documented coronary artery disease. This is an international prospective, multicentre, randomized, double-blind, placebo-controlled, event-driven study of approximately 5000 patients for a targeted 984 events. Patients must have a recent symptomatic exacerbation of HF, increased plasma concentrations of natriuretic peptides (B-type natriuretic peptide ≥200 pg/mL or N-terminal pro-B-type natriuretic peptide ≥800 pg/mL), with left ventricular ejection fraction ≤40% and coronary artery disease. Patients requiring anticoagulation for atrial fibrillation or other conditions will be excluded. After an index event (overnight hospitalization, emergency department or observation unit admission, or unscheduled outpatient parenteral treatment for worsening HF), patients will be randomized 1:1 to rivaroxaban or placebo (with standard of care). The primary efficacy outcome event is a composite of all-cause mortality, myocardial infarction or stroke. The principal safety outcome events are the composite of fatal bleeding or bleeding into a critical space with potential permanent disability, bleeding events requiring hospitalization and major bleeding events according to International Society on Thrombosis and Haemostasis bleeding criteria. COMMANDER HF is the first prospective study of a target-specific oral antithrombotic agent in HF. It will provide important information regarding rivaroxaban use following an HF event in an HF-rEF patient population with coronary artery disease. © 2015 The Authors.

    The first oxycodone once daily (OOD) has been developed and after successful pharmacokinetic characterization, therapeutic efficacy and safety were compared to an established oxycodone twice daily (OTD: Oxygesic/OxyContin, Mundipharma). A randomized, double-blind, multicenter, cross-over, non-inferiority study was conducted in patients (n = 68) with chronic malignant or non-malignant pain. The new OOD was compared to OTD at identical total daily doses (TDD: 40-120 mg/day) employing intensive, five times daily current pain (0-100 mm visual analog scale, VAS) and twice daily 12 h recalled pain assessments as well as safety parameters such as nausea and sedation (VAS) over 5 days for each treatment (after a 5 day run-in phase). There was no significant difference in analgesic potency detected between the two treatments based on 95% CI for difference in the daily mean current pain (-2.09 mm VAS) over 5 days, determined as -5.09 to 0.91 mm VAS. A difference ≤12 mm VAS indicated non-inferiority of OOD, i.e. lack of clinically relevant difference in analgesia. Intake of rescue medication had no effect on study results as evaluated by ANCOVA. The difference in adverse events (AEs) between the two treatments did not reach significance, as 19.1% and 23.5% of patients experienced treatment-related AEs while on OOD and OTD, respectively. Advantages for OOD regarding consistency of analgesia (i.e. use of rescue medication, current and recalled pain) and sedation did not reach statistical significance in this limited study population. Despite the small number of patients and short study duration, the results support the conclusion that new OOD is (at least) equivalent to established OTD regarding safety and efficacy.

    As 6% hydroxyethyl starch (HES) 130/0.40 or 130/0.42 can originate from different vegetable sources, they might have different clinical effects. The purpose of this prospective, randomized, double-blind controlled trial was to compare two balanced tetrastarch solutions, one maize-derived and one potato-derived, on perioperative blood loss in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). We randomly assigned 118 patients undergoing elective cardiac surgery into two groups, to receive either a maize- or a potato-derived HES solution. Study fluids were administered perioperatively (including priming of CPB) until the second postoperative day (POD#2) using a goal directed algorithm. The primary outcome was calculated postoperative blood loss up to POD#2. Secondary outcomes included short-term incidence of acute kidney injury (AKI), and long-term effect (up to one yr) on renal function. Preoperative and intraoperative characteristics of the subjects were similar between groups. Similar volumes of HES were administered (1950 ml [1250-2325] for maize-HES and 2000 ml [1500-2700] for potato-HES; P=0.204). Calculated blood loss (504 ml [413-672] for maize-HES vs 530 ml [468-705] for potato-HES; P=0.107) and the need for blood components were not different between groups. The incidence of AKI was similar in both groups (P=0.111). Plasma creatinine concentration and glomerular filtration rates did vary over time, although changes were minimal. Under our study conditions, HES 130/0.4 or 130/0.42 raw material did not have a significant influence on perioperative blood loss. Moreover, we did not find any effect of tetrastarch raw material composition on short and long-term renal function. EudraCT number: 2011-005920-16. © The Author 2016.

This study aimed to compare the efficacy and tolerability between quetiapine and haloperidol in controlling delirious behavior. Methods: A 7-day prospective, double-blind, randomized controlled trial was conducted from June 2009 to April 2011 in medically ill patients with delirium. Measures used for daily assessment included the Delirium Rating Scale-revised-98 (DRS-R-98 and total sleep time. The Clinical Global Impression, Improvement (CGI–I and the Modified (nine-item Simpson–Angus Scale were applied daily. The primary outcome was the DRS-R-98 severity scores. The data were analyzed on an intention-to-treat basis. Results: Fifty-two subjects (35 males and 17 females were randomized to receive 25–100 mg/day of quetiapine (n = 24 or 0.5–2.0 mg/day of haloperidol (n = 28. Mean (standard deviation doses of quetiapine and haloperidol were 67.6 (9.7 and 0.8 (0.3 mg/day, respectively. Over the trial period, means (standard deviation of the DRS-R-98 severity scores were not significantly different between the quetiapine and haloperidol groups (-22.9 [6.9] versus -21.7 [6.7]; P = 0.59. The DRS-R-98 noncognitive and cognitive subscale scores were not significantly different. At end point, the response and remission rates, the total sleep time, and the Modified (nine-item Simpson–Angus scores were also not significantly different between groups. Hypersomnia was common in the quetiapine-treated patients (33.3%, but not significantly higher than that in the haloperidol-treated group (21.4%.

We evaluated the effects of long-term lysozyme administration on COPD exacerbation. Methods: In a 1-year, randomized, double-blind, placebo-controlled, parallel trial, patients with moderate-to-severe COPD and one or more episodes of COPD exacerbation in the previous year before enrollment were selected. Lysozyme (270 mg or placebo was administered orally for 52 weeks as an add-on to the standard therapies such as bronchodilators. COPD exacerbation, pulmonary function, and COPD assessment test scores were analyzed. An exacerbation was defined as worsening of more than one symptom of COPD (cough, sputum volume, purulent sputum, or breathlessness leading to a change in medication. The primary endpoint was exacerbation rate. Results: A total of 408 patients were randomly assigned to the lysozyme and placebo groups. The baseline characteristics were similar between the two groups. The exacerbation rate was not significantly different between the two groups (1.4 vs 1.2; P=0.292, Poisson regression. However, a subgroup analysis showed that lysozyme might reduce exacerbation rate in patients with airway-dominant phenotype (1.2 vs 1.6. Moreover, the median time to first exacerbation was longer in patients with airway-dominant phenotype in the lysozyme group than that

    Objective We compared the effect of levomepromazine (LMP) with chlorpromazine (CPZ) in treatment-resistant schizophrenia (TRS). Methods We carried out a double-blind, parallel group study (n = 19/arm) with balanced randomization in blocks of 4 and stratification by sex. Subjects entered a 30-week trial, of which phases I–III were open: phase I (wk 0–6) baseline; phase II (wk 7–9) stepwise transition to haloperidol (HAL), 30 mg/d, plus benztropine (BT), 4 mg/d; phase III (wk 10–15) HAL, 40–60 mg/d, plus BT, 4–6 mg/d; phase IV (wk 16–20) stepwise transition to LMP or CPZ (500 mg/d) following randomization; phase V (wk 21–28) stepwise increase of LMP or CPZ (600–1000 mg/d, dose reduction permitted) to establish optimum dose; and phase VI (wk 29–30) optimized dose maintained. Criteria for TRS were based on those established by Kane et al in 1988. The criterion for a response to treatment was a reduction of 25% or more in total Brief Psychiatric Rating Scale score. Results Both LMP (p = 0.007) and CPZ (p = 0.030) improved TRS relative to baseline. Although there was no significant difference between the 2 groups in treatment response at study end point, hierarchical linear modelling of longitudinal outcome revealed a significant (p = 0.006) advantage of LMP over CPZ for the BPRS total score. Ten of 19 participants on LMP and 8 of 19 on CPZ met the criterion for treatment response, and 9 of the 18 responders did so on 200–700 mg/d phenothiazine. The mean dose of responders was 710 (standard deviation [SD] 265) mg/d (LMP) and 722 (SD 272) mg/d (CPZ). Akathisia was associated with a nonresponse to phenothiazines (p = 0.010). BPRS scores increased significantly on HAL (p = 0.006). Two of 19 participants on LMP and 5 of 19 on CPZ withdrew early from the study. Conclusion LMP and CPZ may be useful in the management of TRS. A modest advantage of LMP compared with CPZ was seen in longitudinal analysis. High doses of neuroleptics may contribute to TRS

    Botulinum toxin A (BTA) is considered an effective treatment of blepharospasm and hemifacial spasm, but there are few studies to permit a comparison of its different formulations. This prospective, randomized, double-blind study compared Prosigne, a BTA of Chinese origin, with Botox to establish safety, efficacy, and equivalence of doses between those 2 formulations in blepharospasm and hemifacial spasm treatment. Fifty-seven patients participated in this study: 21 blepharospasm (from whom 11 were treated with Botox; and 10, with Prosigne) and 36 hemifacial spasm patients (17 were treated with Botox; and 19, with Prosigne). All patients were similar in age, disease time span, number of previous shots, and time elapsed since the last BTA application. Pain and burning during the injection and the result of the treatment were similar in both groups. There were no systemic adverse events, and the local ones were observed with similar intensity and frequency for both groups. The mean effect time length was similar for both blepharospasm (11.3 weeks for both toxins) and hemifacial spasm patients (12.8 weeks for Botox and 12.9 weeks for Prosigne). In both blepharospasm groups, only the 36-Item Short-Form Health Survey emotional aspects domain showed improvement from baseline after 16 weeks. There were no differences between the 36-Item Short-Form Health Survey scores before and after the treatment of all hemifacial spasm patients. Therefore, it has been concluded that Botox and Prosigne have similar efficacy, safety, and tolerability profiles, so that a dose equivalence of 1:1 may be considered for blepharospasm and hemifacial spasm treatments.

This was an equally randomized, double-blind, placebo-controlled, parallel-group, single center trial. Adult patients undergoing laparoscopic fundoplication were recruited. The intervention group received 1 mg/kg intravenous lidocaine bolus prior to induction of anesthesia, then an intravenous infusion at 2 mg/kg/h for 24 hours. The primary outcome was pain, measured using a numeric rating scale for 30 hours postoperatively. Secondary outcomes were nausea and vomiting, opioid requirements, adverse events, serum lidocaine concentration, and length of hospital stay. The study was terminated after an interim analysis of 24 patients showed evidence of futility. There was no difference in postoperative pain scores (lidocaine versus control, mean ± standard deviation at rest (2.0 ± 2.7 vs 2.1 ± 2.4, P=0.286 or with movement (2.0 ± 2.6 vs 2.6 ± 2.7, P=0.487. Three adverse events occurred in the lidocaine group (25% of patients. Intravenous lidocaine did not provide clinically significant analgesia to patients undergoing laparoscopic fundoplication. The serum lidocaine concentration of patients who experienced adverse events were within the therapeutic range. This trial cannot confirm the safety of intravenous lidocaine at the dose tested.

    Full Text Available Obesity and its associated cardiometabolic co-morbidities are increasing worldwide. Since thyroid hormone mimetics are capable of uncoupling the beneficial metabolic effects of thyroid hormones from their deleterious effects on heart, bone and muscle, this class of drug is considered as adjacent therapeutics to weight-lowering strategies. This study investigated the safety and efficacy of TRC150094, a thyroid hormone mimetic.This 4-week, randomized, placebo-controlled, double-blind trial was conducted in India and The Netherlands. Forty subjects were randomized at a 1:1 ratio to receive either TRC150094 dosed at 50 mg or placebo once daily for 4 weeks. Hyperinsulinemic euglycemic clamp and (1H-Magnetic Resonance Spectroscopy (MRS were performed before and after treatment.At baseline, subjects were characterized by markedly impaired hepatic and peripheral insulin sensitivity. TRC150094 dosed 50 mg once daily was safe and well tolerated. Hepatic nor peripheral insulin sensitivity improved after TRC150094 treatment, expressed as the suppression of Endogenous Glucose Production from 59.5 to 62.1%; p = 0.477, and the rate of glucose disappearance from 28.8 to 26.4 µmol kg(-1min(-1, p = 0.185. TRC150094 administration did not result in differences in fasting plasma free fatty acids from 0.51 to 0.51 mmol/L, p = 0.887 or in insulin-mediated suppression of lipolysis from 57 to 54%, p = 0.102. Also, intrahepatic triglyceride content was unaltered.Collectively, these data show that, in contrast to the potent metabolic effects in experimental models, TRC150094 at a dose of 50 mg daily does not improve the metabolic homeostasis in subjects at an increased cardiometabolic risk. Further studies are needed to evaluate whether TRC150094 has beneficial effects in patients with more severe metabolic derangement, such as overt diabetes mellitus and hypertriglyceridemia.clinicaltrials.gov NCT01408667.

    Currently available treatment options for impetigo are limited by either systemic side effects (for oral therapy) or lack of ease of use (for topical ointment). A novel foam formulation of minocycline for topical use may improve convenience and treatment utilization for pediatric patients with impetigo. To evaluate the safety and efficacy of topically applied minocycline foam (FMX-102 1% and 4%) in the treatment of impetigo and to determine the optimal therapeutic active ingredient concentration. In this randomized, parallel-group, double-blind, comparative clinical trial, 32 subjects aged ≥2 years with a clinical diagnosis of pure impetigo, impetigo contagiosa, or uncomplicated blistering impetigo were randomized to treatment with FMX-102 1% or 4%, twice daily for 7 days. Subjects were followed for up to 7 days post-treatment. Clinical cure, defined as ≥80% cured lesions (fully recovered lesions, visually determined by investigators), was achieved by 57.1% and 50.0% of FMX-102 1% and 4% subjects, respectively, at the end of treatment (visit 3). Clinical success, defined as the absence of lesions, or the drying or improvement of treated lesions (decrease in size of affected area, lesion number, or both), was demonstrated in 81.3% and 78.6% of FMX-102 1% and 4% subjects, respectively, following 3 days of treatment (visit 2), in 92.3% and 100% of the respective subjects at the end of treatment, and in 100% in both groups at follow-up (visit 4). Bacteriologic success rates at the end of treatment, defined as complete pathogen eradication, were 85% and 74% in the FMX-102 1% and 4% groups, respectively. The bacteriologic success rate for MRSA infections was 100% (11/11), with no recurrences. Both FMX-102 1% and 4% were considered well tolerated and safe. Topical minocycline foam may be a safe and effective new treatment option for impetigo in children, including those with MRSA. J Drugs Dermatol. 2016;15(10):1238-1243.

    This multi-center, randomized, double-blind, phase 3 trial was conducted to compare the safety and efficacy of contrast agents iohexol-380 and iohexol-350 for coronary CT angiography in healthy subjects. Volunteers were randomized to receive 420 mgI/kg of either iohexol-350 or iohexol-380 using a flow rate of 4 mL/sec. All adverse events were recorded. Two blinded readers independently reviewed the CT images and conflicting results were resolved by a third reader. Luminal attenuations (ascending aorta, left main coronary artery, and left ventricle) in Hounsfield units (HUs) and image quality on a 4-point scale were calculated. A total of 225 subjects were given contrast media (115 with iohexol-380 and 110 with iohexol-350). There was no difference in number of adverse drug reactions between groups: 75 events in 56 (48.7%) of 115 subjects in the iohexol-380 group vs. 74 events in 51 (46.4%) of 110 subjects in the iohexol-350 group (p = 0.690). No severe adverse drug reactions were recorded. Neither group showed an increase in serum creatinine. Significant differences in mean density between the groups was found in the ascending aorta: 375.8 ± 71.4 HU with iohexol-380 vs. 356.3 ± 61.5 HU with iohexol-350 (p = 0.030). No significant differences in image quality scores between both groups were observed for all three anatomic evaluations (all, p > 0.05). Iohexol-380 provides improved enhancement of the ascending aorta and similar attenuation of the coronary arteries without any increase in adverse drug reactions, as compared with iohexol-350 using an identical amount of total iodine.

    This study aimed to assess changes in oral health-related quality of life (OHRQoL) in individuals enroled in a double-blind randomized clinical trial conducted to evaluate the efficacy and safety of two carbamide peroxide concentrations used in at-home vital bleaching in the city of Pelotas, Southern Brazil. Ninety-two volunteers with a shade mean of C1 or darker for the six maxillary anterior teeth were randomized into two balanced groups (n=46) according to bleaching agent concentration: 10% or 16% carbamide peroxide. The patients were instructed to use the whitening agent in a tray for 2h once a day for three weeks. To assess changes in OHRQoL, participants completed the oral impact on daily performance (OIDP) at the start and one week after the completion of treatment. Because there was no difference with regard to whitening effect or tooth sensitivity during or after treatment the two groups were merged for the analyses of the current article. Before-and-after changes in OIDP scores were assessed by chi-square and McNemar tests (pdental colour was observed after bleaching (p=0.03). Quality of life is complex and encompasses different domains. Although positive impact of the dental bleaching was detected, with patients showing more their teeth without embarrassment, difficult in dental hygiene and pain resulting from the treatment were also reported, and this can negatively impact daily performances. Dentists must consider these aspects when performing aesthetics procedures. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Medical management is rapidly becoming a very im-portant part of the armamentarium of the urologist in-volved in the treatment of benign prostatic hyperplasia. The commonest options for medical management include alpha-blockers, 5-alpha reductase inhibitors, and pro-gestational anti-androgens. We present a double-blind randomized controlled trial evaluating the safety and efficacy of terazosin, finasteride and allylestrenol, the prototype drugs in each of these respective categories. A total of 140 patients who satisfied the inclusion and exclusion criteria were inducted into the trial after an informed consent. They were randomized into 4 groups, which received placebo, terazosin, finasteride and allylestrenol respectively for 6 months. Since 29 patients did not complete 6 months of therapy, there were 111 evaluable patients at the end of the study. We found that these 3 drugs produce comparable improvement in symp-tom sc
