Active clinical trials for "Diarrhea"

The purpose of this study is to determine if the daily intake of the probiotic Lactobacillus reuteri prevents antibiotic-associated diarrhoea and related Clostridium difficile infections in children and adolescents.

SODISWATER was a health impact assessment study investigating the effect of sunlight to inactivate microbial pathogens in drinking water. This study was carried out by observing whether children younger than 5 years old who drink solar disinfected water were healthier than those who did not. Health was measured by how often the children had diarrhoea or dysentery. Caregivers for the participants were given plastic bottles to place in the sun, water samples were then collected from these plastic bottles to be analyzed. They were also requested to fill in diarrhea diaries. TESTABLE RESEARCH HYPOTHESES: Health Impact Assessment: Children who use solar disinfected water will have: (a) lower morbidity due to non-bloody diarrhoea and bloody diarrhoea (c) increased growth rates (d) lower mortality (e) increased family productivity (f) decreased care-giver burden (g) increased school attendance

The primary objective of this study is to assess the safety and tolerability of rifaximin 600 mg (3 x 200-mg tablets) once daily compared with placebo when taken for 14 days by healthy subjects to prevent travelers' diarrhea (TD) from all causes.

This study is an inpatient trial to determine the safety, immunogenicity and efficacy of the WRSS1 candidate vaccine in healthy Thai adult volunteers.

This is a randomized, double-blind, community-based efficacy trial of different doses, forms, and frequencies of zinc supplementation for the prevention of diarrhea and promotion of linear growth among children 9-11 months of age in Dhaka, Bangladesh.

Vaccines work by stimulating the body to produce a high-quality, rapid and specific immune response upon exposure to infection by a particular disease-causing microorganism - the microorganism targeted by the vaccine. Evidence is emerging that some vaccines may have additional 'non-specific effects' (NSEs); that is, effects on the immune system beyond the direct protection against the diseases for which the vaccines were developed. It has been proposed that rabies vaccine has protective NSEs in people and animals, with receipt of rabies vaccine in children associated with a reduced risk of meningitis and cerebral malaria in one study, and a history of rabies vaccination in free-roaming dogs associated with increased survival rates in another study. Studies in mice have shown that prior rabies vaccination protects against bacterial sepsis. The biological mechanism of action of any such NSE of rabies vaccine is unknown. Other vaccines with reported protective NSEs (e.g. bacillus Calmette-Guerin vaccine against tuberculosis, a disease caused by Mycobacterium tuberculosis) have been show to reprogram the immune system, leading to enhanced protection against infection with disease-causing microorganisms unrelated to M. tuberculosis. In this study, we will test the hypothesis that rabies vaccine has non-specific protective effects against common infectious disease (CID) syndromes (upper respiratory illness, diarrhea and fever) in a population of veterinary students. We will randomly assign previously-unvaccinated students who volunteer for the study to receive a primary course of three injections of rabies vaccine (experimental group) or an identical course of three injections of sterile water (control group). Participants will not know to which group they have been assigned. We will ask all participants to report episodes of illness through an online survey each week for 26 weeks, and will also record all clinically- and laboratory-confirmed cases of illness with CID syndromes. We hypothesize that rates of self-reported new episodes of CID illness over 26 weeks will be at least 25% lower in the experimental group, relative to the control group.

This intervention will experimentally test the hypothesis that sanitation can be improved in a peri-urban setting using state-of-the-art behaviour change communications. Formative research indicated that landlords are the effective decision-makers about investments in sanitation on their plots (which can include a number of tenant households as well). Landlords will therefore be the primary targets of the intervention. The study will take the form of a randomized controlled trial of the intervention evaluated at the plot level. The intervention will invite enrolled landlords to a series of meetings in which various mechanisms will be used, each designed to increase their likelihood of improving the toilet(s) on their plot. These meetings will be the main vehicle for a status-building campaign associated with increasing wealth by improving plot sanitation, understanding tenants' implicit demand, understanding the processes by which toilets can be improved, and a competition rewarding landlords that make the greatest improvements to the improvement of their toilet(s). The desired improvements will be measured via multiple primary outcomes that measure aspects of changes to hardware and software components, including indicators of hygienic quality, psychological desirability, accessibility, and ecological sustainability. This is because the investigators argue that, to have a significant impact on population-level diarrheal disease indicators, any sanitation solution must be: effective at reducing exposure to pathogens (i.e., hygienic), desirable (i.e., seen as valuable or humane), and accessible (i.e., no one excluded), so that it can be used by all for a reasonably long time (i.e., sustainable)

This study will evaluate the safety of a prototype Coli surface antigen 6 (CS6) subunit vaccine (CssBA) alone or in combination with Escherichia coli double mutant heat labile toxin (dmLT) given by intramuscular (IM) injection.

Accidental bowel leakage (fecal incontinence) increases in people who have diarrhea and sensations of urgency to have a bowel movement. Drugs such as loperamide (Imodium) that reduce diarrhea improve accidental bowel leakage, but loperamide has disadvantages: it is difficult to find a dose that does not cause constipation, and it does not reduce urge sensations. Eluxadoline is a new drug that is effective for reducing diarrhea, abdominal pain, and urgency in patients with irritable bowel syndrome, and it may be less likely than loperamide to cause severe constipation. Therefore, eluxadoline may help patients manage accidental bowel leakage caused by diarrhea. The chemical name for Viberzi® is eluxadoline. The primary aims of this study are to find out if eluxadoline at a dose of 100 mg orally twice a day will reduce the average number of days the patient has accidental bowel leakage, and to see if the rate of accidental bowel leakage increases when the patient stops taking eluxadoline. Additional goals are to find out if eluxadoline decreases diarrhea and urge sensations. This is a small (pilot) study to show whether eluxadoline is an effective way of treating accidental bowel leakage. If the study shows this, a larger study will be needed. There are three phases to this 12-week study: (1) A two-week run-in period to see if the patient meets the inclusion criteria. (2) Two months for treatment including one month on eluxadoline and one on placebo (sugar pills) twice a day. (3) A two-week follow-up to see what happens when you stop taking eluxadoline. To participate in the study, patients should be aged 18 or older. Patients with inflammatory bowel disease, anal fissures, or congenital malformations will be excluded. The primary outcome is the average number of days per week with any solid or liquid bowel accidents. Additional information includes: (1) Number of days per week the patient takes loperamide, (2) days per week with loose or watery stools, (3) days per week with moderate to strong urge sensations, and (4) questionnaires to measure the severity of accidental bowel leakage, quality of life, anxiety, and depression. There will be up to 38 patients in the study.

Chemotherapy induced diarrhea is seen in up to 40-80% of patients receiving this treatment for HER2 positive locally advanced or metastatic breast cancer. This diarrhea can significantly impact a patient's quality of life and ability to tolerate chemo/anti-HER2 therapy. This study will look at the efficacy of the drug crofelemer in preventing diarrhea in breast cancer patients.
