Active clinical trials for "Gastroenteritis"

This study will evaluate the immunogenicity and safety of the pertussis component of DTwP (whole-cell pertussis containing vaccine) when administered concomitantly with RotaTeq™ or Rotatrix™.

The study aim is to isolate a single type of patient (pediatric patient with acute gastrointestinal symptoms) and evaluate the use of hypotonic (0.45 NS) vs. isotonic (0.9 NS) fluids in these patients in regards to changes in their serum sodium and iatrogenic hyponatremia.

Background: - Food allergies are characterized by abnormal immune system responses to certain foods, such as peanuts, strawberries, and shellfish. Some individuals with these allergies have immediate allergic reactions on contact with the food in question and need immediate treatment to prevent severe complications. In contrast, eosinophil-associated gastrointestinal disorders are related disorders in which white blood cells in the intestinal tract react to certain foods, causing abdominal pain, nausea, and other digestion problems. Researchers are interested in studying these conditions to better understand how the immune system responds to food allergies. Objectives: To examine how the immune system responds to food allergens. To examine how certain white blood cells contribute to disease in individuals with food allergies and other inflammatory diseases. Eligibility: Individuals between 18 and 65 years of age who have a history of (a) severe allergic reaction to peanuts (and have peanut-specific antibodies), (b) allergy or inflammatory disease, or (c) eosinophil-associated gastrointestinal disorder (with at least two documented food allergies). Healthy volunteers between 18 and 65 years of age who have no known allergies or asthma. Design: All participants will have a screening visit and a procedure visit. The procedure visit will take place within 30 to 60 days of the screening visit, and will take 3 to 4 hours depending on the procedure(s) done. Participants will be screened with a physical examination and medical history, and will provide blood samples for testing. Participants with peanut or other allergies will have additional tests to determine their levels of sensitivity to certain foods. Participants with eosinophil-associated gastrointestinal disorder will provide stool samples for testing. At the procedure visit, participants with peanut allergies and participants with other allergies will provide blood samples and have leukapherisis to collect white blood cells for examination. At the procedure visit, healthy volunteers and participants with eosinophil-associated gastrointestinal disorder will provide blood samples and have leukapherisis to collect white blood cells for examination. In addition, some but not all of these participants will have a procedure called esophagogastroduodenoscopy (EGD), which will examine the esophagus, stomach, and small intestine. Participants who are scheduled to have EGD will be asked to fast for 6 hours before the procedure.

This study will collect demographic and safety information on the use of ROTATEQ™ in the Philippines.

This is a multi-centre (RDH and ASH), phase IV, double-blind, randomised, placebo-controlled Bayesian adaptive trial of oral NTZ for the treatment of acute gastroenteritis requiring admission to hospital. A maximum of 300 children aged between three months and less than five years of age will be enrolled. Study participation is from the point of enrolment until 60 days after enrolment. Enrolment will occur within 48 hours of admission to hospital. Enrolled participants will be randomised 1:1 to Nitazoxanide (NTZ) or placebo. Other treatment and management will be as per the standard of care described in the admitting hospital's guidelines and will be ultimately the decision and responsibility of the named medical consultant. Stool samples will be collected at the point of admission. Solicitation of symptoms will be by review of routinely collected medical data recorded in the participant's medical record, and will be supplemented by completion of study specific diary cards after discharge (for the first 210 enrolments). Attempts will be made to contact participants at day 7 after enrolment (by telephone if already discharged) to ascertain symptoms occurring in the intervening period. At days 30 and 60 (for first 210 enrolments ) and Day 60 (for enrolment #211 onwards) after enrolment a clinical record review will be conducted for all participants to ascertain health care attendances following discharge.

The objectives of the study were to determine whether ondansetron treatment would reduce: the amount of vomiting in the emergency department; the need for intravenous rehydration; and the need for hospitalization.

We hypothesize the herbal preparation will enhance the preschoolers' immune response and when taken prophylactically for 12 weeks will decrease episodes of upper respiratory infections and gastroenteritis in the active versus the control group.

The purpose of the study is assessment of volume status by bedside ultrasound in children with acute gastroenteritis

BioFire Diagnostics, LLC (BioFire) has developed the FilmArray Gastrointestinal (GI) Panel, a rapid, easy to use PCR-based in vitro diagnostic test for the identification of 22 common microorganisms responsible for infectious gastroenteritis (http://filmarray.com/the-panels/) from a stool specimen collected in Cary Blair enteric transport media. The test was made available for sale in the US and EU following FDA clearance and CE marking in May, 2014. The FilmArray GI Panel offers improvements over conventional laboratory testing which include: reduced turnaround time from specimen to result, reduced laboratory labor costs, increased sensitivity and specificity relative to current clinical reference methods, and larger breadth of organism identification than is available using standard methods. Because of these attributes, the results from this test have the potential to enable clinicians to more accurately diagnose and treat GI illness in a reduced time frame. Collaborators at the University of Utah, Brown University/Lifespan, and BioFire Diagnostics have designed a study to evaluate health outcomes of pediatric subjects presenting to emergency departments with GI illness before and after establishing the FilmArray GI Panel as the standard of care method for stool pathogen analysis. It is hypothesized that the rapid (~ 1 hour turnaround time), sensitive, specific, and comprehensive results provided by the FilmArray GI Panel will allow clinicians to more rapidly diagnose GI illness, initiate appropriate therapy and provide guidance when compared to the pre-implementation period.

Background: The incidence of gastrointestinal infections is very high. In Western countries at least 30% of the population suffers from at least one food-borne infection per year. Mostly because of the problem of antibiotic resistance, more emphasis is put on prevention of infections. One of the possibilities is to strengthen human resistance to gut infections by consumption of milk ingredients. Aim: To study whether a milk protein concentrate rich in phospholipids improves the resistance of humans to enterotoxigenic E. coli (ETEC). Study design: The MIRAGE study is a parallel, double-blind, placebo-controlled 4-weeks intervention with a milk protein concentrate rich in phospholipids in healthy subjects of 18-55 yrs of age. Participants will be randomly assigned to the milk protein concentrate rich in phospholipids or placebo group (n=30 per group). Subjects will be instructed to maintain their usual pattern of physical activity and their habitual food intake, but to standardize their dietary calcium intake. After an adaptation period of 2 weeks, subjects will be orally infected with a live, but attenuated, ETEC vaccine (strain E1392-75-2A; collection NIZO food research; dose will be 1010 CFU). Before and after infection, an online diary will be kept to record all food and drinks consumption (2x2 days) to assess the habitual dietary intake. The diary will also be used for daily recording of bowel habits and frequency and severity of gastrointestinal complaints. The following biological samples will be collected: 4x10 ml venous blood, a single fecal bolus (for screening) and 7x24 hrs feces. Blood is sampled for immune response analyses and the fecal samples are collected to quantify several infection- and immune system markers and to verify dietary calcium intake. Saliva is sampled three times before and after infection to quantify immune system markers. Primary outcomes: Fecal ETEC excretion and severity of diarrhea (quantified by fecal output per day). Secondary outcomes: Serum immune response to ETEC, self-reported stool consistency scores and gastrointestinal complaints, relative fecal wet weight.
