Filter by:Rotavirus is the commonest cause of severe gastroenteritis in young children worldwide. The investigators hypothesize that use of a food based prophylactic will decrease incidence of rotavirus infection in young children in south India, prevent intestinal damage and overall result in lower infection rates and better gut function. This trial will evaluate the efficacy of prevention of rotavirus gastroenteritis when an anti-rotavirus protein or antibody fragments expressed in yeast or placebo are given daily as a food supplement to children between the ages of 6 and 12 months. The children will followed for one year and rates of rotavirus diarrhoea, antibody responses and gut function will be compared between children receiving antibody fragments or placebo.
Vomiting in children with acute gastroenteritis is a major factor of failure of oral rehydration therapy. Effective symptomatic treatment of vomiting would lead to an important reduction in the use of Intravenous Fluid Therapy. Available evidence on symptomatic treatment of vomiting shows the efficacy of the most recently registered molecule (ondansetron) but a proper evaluation of antiemetics drugs largely used in clinical practice, such as domperidone, is lacking. The aim of this multicentre, double-blind randomized controlled trial is to compare the efficacy of ondansetron and domperidone for the symptomatic treatment of vomiting in children with acute gastroenteritis who have failed Oral Rehydration Therapy.
The purpose of this hospital based study is to estimate the proportion of rotavirus gastroenteritis in children < 5 years of age in Romania.
This study aims to monitor the incidence rates and duration of hospitalisations for rotavirus gastroenteritis (RV GE) and all cause GE, compared to bronchiolitis from 1998 to 2009, in children < 5 years of age after the introduction of Rotarix in 2006 by year, both inside and outside rotavirus season in Australia. It further aims to compare the two dose regimen of Rotarix with the three dose regimen of RotaTeq from 2007 to 2009.
The primary objective of this study is to compare the efficacy and safety of the use of a multiple electrolyte solution to the use of saline for the treatment of moderate to severe dehydration due to acute gastroenteritis (AGE) in children.
Background: The incidence of gastrointestinal infections is very high. In European countries 10-25% of the population suffers from at least one foodborne infection per year. Probiotics may strengthen human resistance to gut infections as they may beneficially modulate the intestinal microbiota composition and activity, and the immune function upon intestinal infection. Aim: To study whether probiotics improve the resistance of humans to enterotoxigenic E. coli (ETEC). Study design: The PRETEC study is a parallel, double-blind, placebo-controled 4-weeks intervention with probiotics in healthy volunteers. In this study, the effect of probiotic intervention vs placebo on several infection markers in response to an ETEC challenge is investigated. Participants will be randomly assigned to the probiotic or placebo group (n=21 per group). Subjects will be instructed to maintain 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 10E10 CFU). This ETEC strain induces mild and short-lived infectious diarrhea symptoms. Before and after infection, a diary will be kept to write down 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. Blood is sampled for immune response analyses and multiple faecal samples are collected to quantify several infection- and immune system markers, to determine probiotic excretion, and to verify dietary calcium intake. Study population: Healthy males of 20-55 yrs of age. Interventions: Probiotics (freeze-dried powder, dose 10E9 CFU twice daily) or placebo (carrier material powder of identical appearance). Primary outcomes: Total fecal ETEC excretion per day and severity of diarrhea (quantified by faecal output per day). Secondary outcomes: Serum immune response to ETEC, self-reported stool consistency scores and gastrointestinal complaints, relative faecal wet weight, sIgA and calprotectin in faeces, probiotic persistence and levels of opportunistic pathogens in the endogenous microbiota.
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.
The purpose of this study is to evaluate the epidemiology and baseline disease burden of rotavirus gastroenteritis in children < 6 years of age, in Japan.
The purpose of this study is to estimate the disease burden and epidemiology of rotavirus gastroenteritis in children less than 5 years of age, in United Arab Emirates. Acute gastroenteritis cases will be identified from acute gastroenteritis hospitalisation log book and stool samples will be collected from all suspected and confirmed acute gastroenteritis cases.
Rotavirus is one of the most common causes of severe diarrhea, responsible for 40% of all diarrhea related deaths in children worldwide. Two vaccines against Rotavirus, Rotarix® and Rotateq® were licensed in many high and middle income countries in 2006, but lack of efficacy data in low income countries had prevented WHO from making a universal recommendation of their use until recently. This study will be conducted in Pakistan and will look at two objectives: 1. To compare the immunogenicity of Rotarix® vaccine when administered at 6 and 10 weeks of life and at 6, 10 and 14 weeks of life. 2. To compare the immunogenicity of Rotarix® vaccine in infants breast fed at the time of vaccine administration with infants whose breast feeding is withheld for one hour before and after vaccine administration.
