Active clinical trials for "Diarrhea"

The purpose of this study is to study factors (drugs, serum concentration of drugs, nutrition, physical activity, demographics, diseases etc.) related to constipation and diarrhea in nursing homes, and the effect of different laxative regimens.

In many areas of the world most severely affected by the HIV/AIDS pandemic, insect and water-borne diseases such as malaria and diarrheal disease are common causes of illness and death. In addition, diarrhea and malaria are more common and more severe among adults and children infected with HIV. These infections may modulate the immune system, affect the replication of the HIV virus and could result in more rapid HIV disease progression in co-infected individuals. Access to practical, inexpensive and easy to use interventions to prevent these diseases may be effective in delaying HIV progression. Current Kenya government and World Health Organization guidelines recommend the use of cotrimoxazole (trimethoprim-sulfamethoxazole [TMP/SMX]) to prevent co-infections, including malaria. Despite the provision of TMP/SMX to HIV-infected adults, infections with malaria and pathogens causing diarrhea remain common causes of morbidity and mortality in many resource-limited settings. In addition, TMP/SMX may not prevent all infections with malaria or other pathogens due to alternative mechanisms of action, antimicrobial resistance and non-compliance due to adverse events or other reasons. We propose a study to evaluate the impact of providing insecticide treated bednets and a simple water filtration device on markers of HIV disease progression among a cohort of ART naïve, HIV infected adults prescribed TMP/SMX in Kenya. In addition, we propose to evaluate the effect of these interventions on malaria and diarrheal disease incidence and on compliance with TMP/SMX.

Clostridium difficile is responsible for up to 25% of reported antibiotic associated diarrhea cases and virtually all cases of pseudomembranous colitis (PMC). The clinical spectrum of C. difficile infection (CDI) varies in severity from asymptomatic carriage to self-limited, mild, watery diarrhea, to PMC, intestinal perforation, toxic megacolon, sepsis, fulminant colitis, and death. In the past decade, the 027/NAP1/BI strain has emerged world-wide and has been implicated in large outbreaks with increased severity, frequent recurrence, and significant mortality. The host immune responses can influence the severity of CDI and play crucial roles in CDI onset, progression, and overall prognosis. Low serum concentrations of antibodies directed against the toxins A&B of C. difficile have been associated with a higher risk of recurrence. However, there are conflicting reports.

The primary objective of this study is to determine whether giving SBI as a medical food starting with maintenance of health in the management of chronic loose and frequent stools in IBS-D subjects with SIBO after successful treatment with rifaximin can lead to more prolonged duration of benefit and delay symptom recurrence. SBI is the main ingredient in EnteraGam™, an orally administered prescription medical food for the dietary management of patients with enteropathy or chronic loose or frequent stools, including patients with IBS-D.

The purpose of this study is to learn whether bismuth subsalicylate can reduce use of antibiotics among adults with diarrhea in Pakistan.

This prospective, multicenter, randomized, double-blind, placebo-controlled clinical study, into the group of children in the hospital that use clinical antibiotics from one month to three years old，by observing the given antibiotics at the same time with the whole bowel raw or placebo, prevent the happening of the antibiotic associated diarrhea, evaluate the whole bowel prevention clinical efficacy and safety of AAD.

The investigators aim to evaluated a public health program in Haiti that introduced an oral cholera vaccine as part of comprehensive control efforts for a major cholera epidemic. Although the vaccine (Shanchol(R)) had been demonstrated to be very safe, and effective at preventing cholera in many settings, it had not extensively been used to control an outbreak, and it had not been extensively studied in populations that were previously naive to cholera (i.e. countries that had never had cholera before). This cholera epidemic was the first ever report of cholera in Haiti. After the cholera vaccination campaign was complete, the investigators aimed to evaluate the field efficacy of the vaccination campaign by evaluating the number of cases of cholera, and determining if cholera patients had been vaccinated. The investigators compared the rate of vaccination in cholera cases to controls from the community that had not had cholera in a case-control study. The investigators also performed a second study - a bias-indicator study - that enrolled patients with non-cholera diarrhea, and community controls. The role of the bias-indicator study was to evaluate for potential sources of bias, since the investigators could expect that cholera vaccination should have no effect on non-cholera diarrhea.

The mechanisms of diarrhoea under metformin are poorly known. Recent data indicate that a change in gut flora might be responsible for this intestinal disorder. The effect of metformin on the gut flora has been extensively described. It has been shown that the therapeutic effect of metformin depends on the microbiota. In agreement with these data, a recent publication has shown that metformin's main site of action in humans was the intestine. In light of these results, it now seems plausible that metformin's effect on the gut flora is responsible not only for its therapeutic effect but also for its undesirable digestive effects. In this respect, Lactobacillus rhamnosus has shown anti-diarrhoeal effects (approximately 50% reduction in diarrhoeas) in the contexts of infection-caused dysbiosis and post-antibiotic dysbiosis. Hypothesis: Taking into account the favourable effect on intestinal dysbiosis-induced diarrhoeas observed with Lactobacillus rhamnosus, we put forward the hypothesis that Lactobacillus rhamnosus Lcr35® will have a favourable effect on metformin-induced diarrhoea.

Placebo controlled double-blind study with 40 patients who have an diarrhea-predominant IBS, 20 get Neu-P11, 20 get a placebo. Neu-P11 is a, Melatonin receptor-, Serotonin 5-HT- 1A and 5-HT- 1D - agonist and a serotonin 5-HT- 2B - antagonist.

This will be a strain and dose-finding study in which CS19-ETEC strain WS0115A will be administered at a starting inoculum of 5 x 108 colony forming units (cfu) to 5 subjects as the initial step to establish a human disease model. If an 80% attack rate (AR) for predefined diarrheal disease is achieved without high output diarrhea, the same inoculum will be given to 5 - 10 more subjects for confirmation of AR. If an 80% AR is not achieved, AR and severity of disease will be evaluated to determine if the dose should be increased. The same sequence may be conducted with DS26-1 as necessary. If the WS0115A strain causes high output diarrhea, the dose will be adjusted down and further dose characterization continued. An iterative process will be used to select the optimal strain and dose with each step reviewed and approved by the medical monitor.
