Active clinical trials for "Diarrhea"

The purpose of this study is to evaluate if ingestion of a probiotic formula (Jarrow-Dophilus EPS)reduces incidence of diarrhea and improves the quality of life of patients receiving antibiotic therapy.

The purpose of this study is to determine if 600 mg of rifaximin, taken once a day for 14 days by healthy subjects, is safe and effective for the prevention of travellers' diarrhea compared to placebo.

This is a research study about an experimental (investigational) vaccine called ACE527. ACE527 is a vaccine that is being made to prevent disease from a germ called enterotoxigenic Escherichia coli (ETEC). This germ causes diarrhea, largely in children living in developing countries and in travelers to those countries. One purpose of this study is to see if the vaccine is safe and develops an immune response. Another purpose is to see if it prevents people from getting sick when exposed to the ETEC germ. This ETEC germ is also experimental (investigational).

The purpose of this study is to evaluate the efficacy of the Travelers' Diarrhea Vaccine System to actively immunize against Enterotoxigenic Escherichia coli disease in a field setting.

Diarrhea is a common side effect of antibiotics; it may prolong hospital stay, increase the risk of other infections, develop into more serious forms of disease, and lead to premature discontinuation of the needed antibiotic. The purpose of this study is to examine the safety and effectiveness of a capsule containing Lactobacillus rhamnosus GG in the prevention of diarrhea associated with antibiotic use.

The study will compare durations of diarrhea among subjects who report to clinic for treatment and who receive either: standard rifaximin therapy at a dose of 200 mg three times a day for 3 days, OR a single 600 mg dose of rifaximin daily for 3 days.

This study will evaluate the efficacy of Octreotide LAR in preventing chemotherapy-induced diarrhea (with regimens that contain 5 fluorouracil, irinotecan and capecitabine)in patients with colorectal cancer.

Vitamin A deficiency in children is associated with increased mortality and morbidity due to respiratory tract and diarrhoeal infections. Vitamin A supplementation has been shown in some studies to reduce morbidity due to respiratory diseases. However, other studies to reduce could not document such benefit from vitamin A supplementation. The role of vitamin A on immunity in humans is not yet clear due to inconclusive results. To evaluate immune changes and compare those with of a known immunopotent agent like zinc, a randomised double blind study will be carried out in 1-3 year aged children without acute illness and wt/age between 61% and 70% of NCHS standard. Baseline anthropometry and vitamin A status will be determined using MRDR test and immune status will be estimated. Each group consisting of 50 children will either receive vitamin A 200,000 IU over 7 days or 40 m elemental zinc daily for 7 days or both or placebo. After 8 weeks immunity test will be repeated. Immunity tests will include serum 1gA, 1gM, 1gG an lymphocyte simulation and 8 antigen multiple skin test. Undiminished children will be given measles vaccine and serum titre will be measured before and after supplementation. Vitamin A status will be estimated by MRDR test. Vitamin A2 will be given and 1ml blood sample will be collected after 5 hours to see the ratio of vitamin A1 and A2 (<0.06 as cut off) as the modified relative dose response (MRDR test). Doses of vitamin A or zinc will be repeated at the completion of 2 month. The results will be compared between groups and within groups at baseline and after 6 weeks. The study will generate information which will help to examine the immune response of vitamin A therapy in children as an underlying factor for reduction in mortality or morbidity. The study will be completed within a year.

Currently there is an ongoing clinical trial for patients with chemotherapy induced diarrhea. This trial is being conducted to evaluate the efficacy of two dose levels (30 mg and 40 mg) of an investigational drug in reducing the occurrence of severe (Grade 3 or 4) diarrhea during chemotherapy. Eligible patients must either have experienced NCI Common Toxicity Grade 1 - 4 chemotherapy-induced diarrhea during previous chemotherapy treatment or be experiencing Grade 1-4 chemotherapy-induced diarrhea currently. In order to participate in this clinical trial, patients must be male or female 18 years of age or older. Inclusion into this investigational drug trial is based on the protocol entry criteria and a detailed evaluation from a participating trial investigator

The purpose of this study is to evaluate the effectiveness of poorly absorbed rifaximin in the prevention of travelers' diarrhea among U.S. college students in Mexico for five weeks.
