Randomized, double-blind, placebo-controlled, interventional phase IV investigation to assess the efficacy and safety of r-hirudin gel (1120I.U) in patients with hematomas.

ABSTRACT: Background:Hirudin is the most potent direct thrombin inhibitor, and recombinant forms are routinely used in anticoagulation therapy. Recombinant hirudin gels are commercially available for the treatment of hematomas and associated symptoms. Objectives:To assess the efficacy and safety of a topically administered recombinant hirudin gel in patients with hematomas. Patients/Methods:This double-blind, placebo-controlled, phase IV investigation recruited patients presenting with at least one hematoma. Subjects were randomly assigned (1:1) recombinant hirudin gel (1120 IU/100 g) or a placebo, administered 2-3 times daily for 16 days. Changes in hematoma size, flare, and the proportion of patients achieving complete resolution of hematomas and associated edemas were investigated. Results:By study end, a greater proportion of subjects in the treatment group achieved a complete resolution of hematomas versus placebo (98.0% vs 71.9%; P < .001) and edemas (99% vs 50%; P < .001). Patients in the recombinant hirudin group exhibited a marginally larger, yet significant, reduction in mean hematoma size versus placebo (99.9% vs 96.6%; P < .001) and flare (93.6% vs 78.6%; P < .001). Median time to hematoma resolution for the recombinant hirudin and placebo administered cohorts was 8 and 16 days, respectively (P < .001). No adverse events were reported for the recombinant hirudin cohort. Conclusions:Topical recombinant hirudin is an effective, safe, and well tolerated intervention for the symptomatic treatment of hematomas. This trial was registered at http://www.clinicaltrials.gov as NCT01960569.

Project description:BackgroundNeck pain (NP) is a common musculoskeletal disorder in primary care that frequently causes discomfort. Non-steroidal anti-inflammatory drugs (NSAIDs) may be used to reduce neck pain and associated inflammation and facilitate earlier recovery. Topical diclofenac diethylamine (DDEA) 1.16% gel is clinically proven to be effective and well tolerated in acute and chronic musculoskeletal conditions, but until now no clinical data existed for its use in acute NP. The aim of this study was to assess the efficacy and safety of DDEA 1.16% gel compared with placebo gel in acute NP.MethodsIn a randomized, double-blind, placebo-controlled study, patients with acute NP (n = 72) were treated with DDEA 1.16% gel (2 g, 4x/day, for 5 days) or placebo. Efficacy assessments included pain-on-movement (POM), pain-at-rest (PAR), functional neck disability index (NDI) and response to treatment (decrease in POM by 50% after 48 h). Adverse events (AEs) were recorded throughout the study.ResultsThe primary outcome, POM at 48 h, was statistically significantly lower with DDEA gel (19.5 mm) vs. placebo (56.9 mm) (p < 0.0001), representing a clinically relevant decrease from baseline (75% vs. 23%, respectively). All POM scores were significantly lower with DDEA gel vs. placebo from 1 h, as were PAR and NDI scores from first assessment (24 h) onwards (all p < 0.0001). Response to treatment was significantly higher with DDEA gel (94.4%) vs. placebo (8.3%) (p < 0.0001). There were no AEs with DDEA gel.ConclusionsDDEA 1.16% gel, which is available over-the-counter, was effective and well tolerated in the treatment of acute neck pain. The tools used to assess efficacy suggest that it quickly reduced neck pain and improved neck function. However, questions remain regarding the comparability and validity of such tools. Further studies will help ascertain whether DDEA 1.16% gel offers an alternative treatment option in this common, often debilitating condition.Trial registrationClinicalTrials.gov identifier: NCT01335724.

Project description:To compare the efficacy and safety of scheduled low-dose haloperidol versus placebo for the prevention of delirium (Intensive Care Delirium Screening Checklist ? 4) administered to critically ill adults with subsyndromal delirium (Intensive Care Delirium Screening Checklist = 1-3).Randomized, double-blind, placebo-controlled trial.Three 10-bed ICUs (two medical and one surgical) at an academic medical center in the United States.Sixty-eight mechanically ventilated patients with subsyndromal delirium without complicating neurologic conditions, cardiac surgery, or requiring deep sedation.Patients were randomly assigned to receive IV haloperidol 1 mg or placebo every 6 hours until delirium occurred (Intensive Care Delirium Screening Checklist ? 4 with psychiatric confirmation), 10 days of therapy had elapsed, or ICU discharge.Baseline characteristics were similar between the haloperidol (n = 34) and placebo (n = 34) groups. A similar number of patients given haloperidol (12/34 [35%]) and placebo (8/34 [23%]) developed delirium (p = 0.29). Haloperidol use reduced the hours per study day spent agitated (Sedation Agitation Scale ? 5) (p = 0.008), but it did not influence the proportion of 12-hour ICU shifts patients spent alive without coma (Sedation Agitation Scale ? 2) or delirium (p = 0.36), the time to first delirium occurrence (p = 0.22), nor delirium duration (p = 0.26). Days of mechanical ventilation (p = 0.80), ICU mortality (p = 0.55), and ICU patient disposition (p = 0.22) were similar in the two groups. The proportion of patients who developed corrected QT-interval prolongation (p = 0.16), extrapyramidal symptoms (p = 0.31), excessive sedation (p = 0.31), or new-onset hypotension (p = 1.0) that resulted in study drug discontinuation was comparable between the two groups.Low-dose scheduled haloperidol, initiated early in the ICU stay, does not prevent delirium and has little therapeutic advantage in mechanically ventilated, critically ill adults with subsyndromal delirium.

Project description:BACKGROUND:Dyslipidemia is one of the most frequently implicated risk factors for development of atherosclerosis. This study evaluated the efficacy of amla (Emblica officinalis) extract (composed of polyphenols, triterpenoids, oils etc. as found in the fresh wild amla fruit) in patients with dyslipidemia. METHODS:A total of 98 dyslipidemic patients were enrolled and divided into amla and placebo groups. Amla extract (500?mg) or a matching placebo capsule was administered twice daily for 12?weeks to the respective group of patients. The patients were followed up for 12?weeks and efficacy of study medication was assessed by analyzing lipid profile. Other parameters evaluated were apolipoprotein B (Apo B), apolipoprotein A1 (Apo A1), Coenzyme Q10 (CoQ10), high-sensitive C-reactive protein (hsCRP), fasting blood sugar (FBS), homocysteine and thyroid stimulating hormone (TSH). RESULTS:In 12?weeks, the major lipids such as total cholesterol (TC) (p?=?0.0003), triglyceride (TG) (p?=?0.0003), low density lipoprotein cholesterol (LDL-C) (p?=?0.0064) and very low density lipoprotein cholesterol (VLDL-C) (p?=?0.0001) were significantly lower in amla group as compared to placebo group. Additionally, a 39% reduction in atherogenic index of the plasma (AIP) (p?=?0.0177) was also noted in amla group. The ratio of Apo B to Apo A1 was reduced more (p?=?0.0866) in the amla group as compared to the placebo. There was no significant change in CoQ10 level of amla (p?=?0.2942) or placebo groups (p?=?0.6744). Although there was a general trend of FBS reduction, the numbers of participants who may be classified as pre-diabetes and diabetes groups (FBS?>?100?mg/dl) in the amla group were only 8. These results show that the amla extract used in the study is potentially a hypoglycaemic as well. However, this needs reconfirmation in a larger study. CONCLUSIONS:The Amla extract has shown significant potential in reducing TC and TG levels as well as lipid ratios, AIP and apoB/apo A-I in dyslipidemic persons and thus has scope to treat general as well as diabetic dyslipidemia. A single agent to reduce cholesterol as well as TG is rare. Cholesterol reduction is achieved without concomitant reduction of Co Q10, in contrast to what is observed with statins.
