Active clinical trials for "Gastroenteritis"

The main aim of this study is to investigate cases of rotavirus gastroenteritis in Belgian children with opportunity to receive Rotarix™ to monitor the potential occurrence of genetic drifts (point mutations) in the vaccine strain and the occurrence of genetic shifts (re-assortments) between vaccine and naturally circulating wild-type strains in Belgium population after the introduction of Rotarix™. The study will also detect if there is any alteration in rotavirus pathogenicity conferred by re-assortment and if the mutated vaccine strain is still efficacious in preventing rotavirus gastroenteritis.

This study was designed to support site preparation and to conduct a disease burden study for the planning and implementation of the phase III trials for the oral rotavirus vaccine 116E.

Rotavirus (RV) is the leading cause of severe gastroenteritis (GE) in young children. The cumulative risk of GE hospitalizations and hospital stays of < 24 hours is 1/25, which would amount to 13,600 Canadian children < 5 years. The incidence of nosocomial RV infections is an average of 8/10,000 patient-days in children < 5 years. An immunization program with a live-attenuated monovalent oral RV vaccine (RV1 - Rotarix® from GSK) will be implemented, free of charge, in the Province of Quebec in November 2011. To provide an accurate portrait of the disease and give critical information to the public health agencies as they struggle to control costs, we aim to evaluate the accuracy of surveillance for RV and other diseases with similar characteristics; estimate selection bias in passive laboratory-based surveillance; and estimate the agreement between surveillance time-series created from passive and active surveillance data sources.

The purpose of this study is to conduct a translational study in patients with primary eosinophil associated gastrointestinal disorders [EGID] (e.g. eosinophilic esophagitis eosinophilic gastritis, eosinophilic enteritis [EE], eosinophilic colitis, and eosinophilic gastroenteritis [EGE]) with the aim of developing a data bank containing pertinent patient demographic information, tissue samples, and DNA, which will facilitate research on the pathophysiology of inflammatory disorders and the development of a verified successful clinical treatment program.

Acute Bacterial dysentery leads to chronic symptoms of disturbed bowel habit in a minority of individuals. This condition known as post infectious irritable bowel syndrome (PI-IBS) remains poorly understood. This could allow material in the bowel to reach deeper tissues of the bowel wall leading to inflammation and changes in muscle and nerve function. This is also early evidence that genetic programming of people with PI-IBS prevents them from turning off inflammation once it begins. Literature suggests that IBS may develop at greater rates in individuals with pro-inflammatory genotype and that these individuals may be at increased risk of inflammatory bowel diseases (IBD).

This project aims to assess the impact of rotavirus vaccine introduction on severe gastroenteritis in South Australian children. Prevalence of rotavirus coded hospitalisations and all-cause gastroenteritis hospitalisations will be compared for a two year period prior to introduction of the vaccine and a two year period following introduction of the vaccine. Severity of rotavirus coded admissions during the periods will also be assessed. Hypotheses: Introduction of the rotavirus vaccine will result in an 80% reduction in hospitalisations for rotavirus positive gastroenteritis (ICD code A0.80) in children less than two years of age. Introduction of rotavirus vaccine will result in an 80% reduction in Paediatric Emergency presentations for rotavirus positive gastroenteritis in children under two years of age. Introduction of the rotavirus vaccine will result in a 50% reduction in hospitalisations for all cause gastroenteritis (ICD codes A0.00-A0.90) in children less than two years of age. Introduction of the rotavirus vaccine will result in a 50% reduction in Paediatric Emergency presentations for all cause gastroenteritis in children less than two years of age. Introduction of rotavirus vaccine will result in a reduction in hospitalisation and Paediatric Emergency presentations in children aged four and five years with rotavirus positive gastroenteritis (unvaccinated cohort). There will be no difference in severity of disease as scored by the Vesikari and/or clark severity score prior to and post introduction of rotavirus vaccine

The Shared Health CHR™ (Clinical Health Record) offers point-of-care clinical reporting and decision support based primarily on patient claims data aggregated across various health care settings, and is one example of the types of health information data exchange efforts being implemented across the country. This study will evaluate how the CHR is used and its clinical and financial impact to better understand the CHR's value, and to identify opportunities to enhance the system to support patient care and practice efficiency. In addition, the results from this study will help to inform the national debate about the effectiveness of these types of tools to maximize patient quality of care, patient safety, and practice efficiency.

Rotavirus Hospital Admissions Surveillance Retrospective surveillance for 2010 and 2011 for hospital admissions in children aged 0 to 16 years due to rotavirus gastroenteritis will be completed by all centers of the IMPACT (Immunization Monitoring Program, ACTive) pediatric hospital network. Prospective surveillance of rotavirus-related admissions for children aged 0 to 16 years was conducted in 2012-20 inclusive and will be performed for an additional 2 years until the end of 2022 at all 12 sites. Surveillance methodology will continue using the same case-finding strategy and the same case report form as in past surveillance (Case reporting is done electronically. Emergency Department Burden of Disease Case finding for all-cause diarrheal illness using ICD codes was undertaken prospectively for 2012 to 2014 and will not continue in the years 2015-17 inclusive. Systematic stool sampling was carried out for cases of gastroenteritis in children < 5 years of age presenting to the ED departments at the IMPACT hospitals in 2012 and 2013 and 5 of the 12 center hospitals in 2014. This component will not continue in to the 2015-17 protocol study years. However the admitted cases presenting to the IMPACT center hospitals with positive rotavirus will be reported and stool samples saved for genotyping at a later date.

The investigators are studying prospectively the difference in axilo-rectal temperature in patients with acute appendicitis and using as a control group patients consulting with acute gastroenteritis at our emergency unit.

This study is designed to estimate the changes in the etiology and epidemiology of acute gastroenteritis in children aged less than 18 years after the implementation of rotavirus vaccine in the Estonian national immunization program in July 2014.
