Active clinical trials for "Diarrhea"

This clinical study is conducted to assess the efficacy of cadazolid compared to vancomycin in subjects with Clostridium difficile-associated diarrhea (CDAD).

The overall aim is to characterize and to compare the extent and quantity of C. difficile stool shedding, perianal colonization and environmental contamination in patients who received oral fidaxomicin, oral metronidazole, or oral vancomycin. This is a prospective, randomized, microbiologic and molecular, study of environmental contamination from patients with proven C. difficile associated diarrhea (CDAD).

This study is being conducted to evaluate the safety and tolerability of crofelemer 125 mg twice a day, taken orally, over 48 weeks of therapy in human immunodeficiency virus-positive (HIV+) subjects with diarrhea.

The purpose of this study is to find whether treating patients with diarrhea predominant Irritable Bowel Syndrome (IBS) with an anti-inflammatory drug called Mesalamine will help improve their symptoms of diarrhea, bloating and abdominal pain.

This trial is to assess the effectiveness of three types of acupuncture for patients with functional diarrhea comparing to a positive drug control.

This is a research study about an experimental (investigational) oral ETEC vaccine (ACE527). ACE527 is a live attenuated vaccine that is being made to prevent disease from enterotoxigenic Escherichia coli (ETEC), which causes watery diarrhea, largely in children living in developing countries and in travelers to those countries. This research study is also testing an investigational adjuvant called dmLT. An adjuvant is something that is added to a vaccine to make it work better. The purpose of this study is two-fold. First, Part A aims to find out if the vaccine by itself or the vaccine combined with the adjuvant is safe, tolerable, and initiates an immune response. Second, Part B aims to find out if the vaccine by itself or the vaccine combined with the adjuvant prevents diarrheal disease when challenged with ETEC H10407. About 60 healthy adults, ages 18-50, will participate in Part A, and they will be required to stay in the research facility for several nights for the first dose, but will not be required to stay overnight for the second and third doses. Participants will be assigned to receive either the vaccine alone, the vaccine with adjuvant, or placebo by mouth. Study procedures include: stool samples, blood samples, and documentation of side effects. Participants will be involved in study related procedures for about 8 months. Interested volunteers from Part A will along with volunteers who were never vaccinated in Part A will return to participate in Part B. These volunteers will be required to stay overnight in the research facility for several nights after challenge, after which they will be treated with antibiotics and sent home. Study procedures include stool samples, blood samples, and documentation of infection with ETEC H10407. If the vaccine with/without adjuvant is effective, the volunteers should not development diarrhea, but if the vaccine with/without adjuvant is not effective, the volunteers will have diarrhea for a few days.

The specific hypotheses are: Gluten supplementation for four weeks increases small intestinal permeability and accelerates colonic transit in patients with irritable bowel syndrome with diarrhea (IBS-D) or functional diarrhea (FD) who are HLA-DQ2 positive.

Rationale: Acute diarrhea (AD) is still a significant morbidity-mortality problem worldwide. Although oral rehydration therapy is the cornerstone, its anti-diarrheal effect is a controversial subject. Since ten years ago, Racecadotrilo´s safety and efficacy had been proved. However, a pharmacoeconomics analysis on this therapeutics has not been published yet. Objective: Evaluate the efficacy, safety, tolerability and costs associated with Racecadotril administration in comparison to a placebo in infants up to 24 months of age with AD in a hospital (mildly or moderately dehydrated) and ambulatory (no dehydrated) settings at the National Institute of Pediatrics in Mexico. Material and Methods: Randomized, double-blind, placebo controlled, clinical trial (RDBCCT) with pharmacoeconomics analysis (cost minimization) to realize in 454 infants with AD (270 hospitalized and 184 outpatients), 1 to 24 months of age who concomitantly will receive ORT and Racecadotril (1.5mg./Kg./t.i.d. doe 5 days) (ORT-Rac Group) or placebo (ORT-Placebo Group). The clinical outcomes in the hospitalized infants to measure will be a) Stool output rate at 48hs. and at the end of the study; b) duration of diarrhea; c) percentage of intravenous (IV) needs and d) percentage of adverse events. The outcome variables in outpatient infants to measure will be a) total liquid and semi-liquid bowel movements during the study; b) duration of diarrhea and c) percentage of adverse events. The pharmacoeconomics analysis will involve a cost minimization analysis (CMA). Results will be analyzed through bi and multivariate analysis using STATA 11.0 for Mac, considering a p value < 0.05 as significant. The pharmacoeconomics model will made through decisions trees using TreAge Pro Healthcare v 1.2.0, 2009.

When patients in hospitals receive antibiotics they often develop diarrhoea. The consequences may be grave for the patient. Thus far, no preventive measure is available. The investigators hypothesize that the apathogenic yeast Saccharomyces boulardii, administered in addition to the antibiotic, may prevent episodes of diarrhoea or may lead to less pronounced diarrhoea. To test this hypothesis, the investigators are carrying out a clinical trial in 1520 adult patients in several hospitals.

This is a prospective, non-comparative, interventional, observational pilot study of the safety and pharmacokinetics of intravenous (IV) tigecycline in conjunction with standard oral therapy in patients with known mild to severe confirmed Clostridium difficile associated diarrhea (CDAD).
