Active clinical trials for "Diarrhea"

Following surgery some patients are unable to swallow. For those requiring nutritional support a tube is sometimes passed through the nose into the stomach to provide feeding. Traditionally this type of feeding is given slowly over the course of the day. However, it is thought that this mode of feeding might increase the amount of fluid entering the bowel contributing to symptoms of diarrhoea. An alternative strategy of feeding, given in larger volumes in a shorter space of time resembles normal feeding patterns and may reduce the amount of water entering the bowel. In this study we want to use a non invasive medical imaging technique called "magnetic resonance imaging" (or MRI) to look at the volume of bowel water following these two feeding strategies in 12 healthy volunteers. Each volunteer will have a tube inserted into the stomach via the nose and undergo the two feeding strategies at least 7 days apart. We will take repeated images using the MRI scanner to assess the bowel response and some samples of blood are required for analysis of blood sugar.

RATIONALE: Genetic testing may help predict how patients will respond to chemotherapy drugs and may help doctors plan more effective treatment with fewer side effects. PURPOSE: Genetic study to determine how genes affect the severity of diarrhea in patients with stage III colon cancer who are receiving chemotherapy.

D.fragilis is an intestinal protozoon that feeds by phagocytosis of intestinal bacteria. The study aim to determine if the carriage of the intestinal parasite D.fragilis is associated to changes of gut microbiota in subjects presenting with or without intestinal symptoms.

The rapid diarrhea that patients experience who have diarrhea occurring after eating specific foods may be causing a "physiologic gastric dumping syndrome". This means that rather than the food being kept in the stomach for normal digestion, it rapidly goes into the small intestine and diarrhea occurs. This study is designed to measure how fast the food empties from the stomach when a person with this problem consumes a "regular diet", compared to a meal with a "triggering substance". Each participant will swallow a radio frequency capsule that with the different meals that will show how fast the food is traveling through the intestines in the different situations.

Background: Many people suffer from diarrhea every year. In the United States, it leads to about 130,000 hospitalizations and 3,000 deaths a year. Researchers want to test a tool that may show them what germs cause diarrhea. It is a simple paper strip test and doesn t require electric power. This may make it easier for health care workers to more quickly fight diarrheal diseases. Objective: To test a tool that may detect what germs cause diarrhea. Eligibility: People already enrolled in an active NIH protocol who have diarrhea Design: Participants will have 1 or 2 studies. They will give information about their symptoms, current medicines, and basic personal data. They will give a stool sample. Part of each sample will be tested in a lab. The rest will be stored indefinitely. No personal data will be connected to the samples. The stored samples may be used in future research. Positive test results will be reported to a participant s primary doctor

OBJECTIVE: To gain mechanistic insights, we will compare effects of low fermentable oligosaccharides, disaccharides and monosaccharides and polyols (FODMAP) and high FODMAP diets on symptoms and colonic protease expression in patients with diarrhea predominant irritable bowel syndrome (IBS-D). We will measure how protease changes affect excitability of pain sensing neurons and correlate this with measurements of the metabolome and the microbiome. DESIGN: We aim to perform a single blind prospective study of patients with diarrhea predominant IBS (Rome IV criteria) who will sequentially consume a high and low FODMAP diets, each for 3 weeks. Symptoms will be assessed using the IBS symptom severity scoring (IBS-SSS). Electrophysiological studies of changes in mouse dorsal root ganglia neurons in response to colonic mucosal/lamina propria supernatants will be carried out. Protease antagonist will be used to specifically assess protease expression. The metabolome will be evaluated using metabolic profiling in urine using mass spectrometry. Stool microbiota composition will be analysed by 16S rRNA gene profiling. All the above testing will be performed at 4 time points: at baseline, 3 weeks following a run-in period, after a 3-week-long high FODMAP diet, and after a 3-week-long low FODMAP diet period. HYPOTHESIS: We anticipate that colonic tissue protease effects on the excitability of dorsal root ganglia (DRG) neurons will increase with a high FODMAP diet and decrease with a low FODMAP diet, but that this may not be found in all patients. The magnitude of the effect may vary and this variation could be due to differences in the individual patients microbiome.

This study will provide important evidence to the Ministry of Community Development, Mother and Child Health (MCDMCH) and the Ministry of Health (MOH) on how to effectively implement iCCM with a focus on improving both the flow of supplies to CHWs as well as the quality of their supervision and mentorship. The overall aim will be to determine whether improvements in supplies for community health workers (CHWs) and strengthened supervision result in improved early and appropriate treatment for children with malaria, pneumonia, and diarrhea in rural Zambia when compared to CHWs offering iCCM without this logistics and supervision support.

The purpose of this study is to determine whether the probiotic Infloran is cost-effective in treating acute childhood diarrhea.

The NET-PACS trial is a Prospective Assessment of patients with neuroendocrine tumors and current or prior history of Carcinoid Syndrome or diarrhea undergoing peptide receptor radionuclide therapy with or without telotristat ethyl. The main goal of the study is to demonstrate the feasibility of serial in-depth assessment of patients with neuroendocrine tumors and current or prior history of carcinoid syndrome or diarrhea undergoing treatment with PRRT using telotristat ethyl compared to placebo. We aim to report and describe from a patient's perspective the multi-faceted impact of carcinoid syndrome in patients with NETs and the changes on treatment while getting PRRT using telotristat ethyl compared to placebo.

This is a retrospective study designed to gather outcomes data from existing medical charts from patients who have taken EnteraGam for management of their IBS-D for at least eight weeks. Data from two study periods will be collected: (1) the time during which the Standard of Care (SOC) therapy (i.e., prescribed or over-the-counter as well as FDA-approved or non-approved agents) that is used immediately prior to prescribing EnteraGam; and (2) the time during which EnteraGam is used as therapy.
