Active clinical trials for "Gastroenteritis"

The ARIES Norovirus Assay is a real-time PCR based qualitative in vitro diagnostic test for the direct detection of Norovirus GI/GII RNA from stool specimens obtained from symptomatic patients. The purpose of this study is to establish the diagnostic accuracy of ARIES Norovirus Assay.

With the use of molecular methods new viruses have been detected in respiratory and gastrointestinal tracts of both patients and asymptomatic subjects in recent years. The clinical importance of these viruses has not been adequately studied. The aim of this study is to use molecular methods to detect viruses in upper respiratory tract and gastrointestinal tract of children with acute bronchiolitis, acute gastroenteritis and febrile convulsions and to try to correlate the severity of clinical picture with the amount of viruses present in clinical samples. The investigators will also try to detect the increase in specific antibodies in paired sera.

Epidemiological studies have shown the diversity of resistance genotypes and the evolution of their prevalence in the paediatric population. This large study conducted in a context of very low vaccination coverage will generate more precise data on the natural epidemiological evolution of rotavirus, notably the G9 genotype, which has appeared relatively recently. This study will allow us to identify and document rare or unusual strains of human or animal origin. The complete genetic characterization of these strains will also make it possible to study their ability to recombine and to assess the risk of emergence. Among these still rare strains, the investigators are particularly monitoring G12 rotavirus, whose ability to recombine raises the risk of emergence. For at least one of the centres taking part in the study, the paediatric population studied will be given strong vaccination coverage. It will be extremely interesting to compare the results obtained in the vaccinated population with non-vaccinated children to assess the impact of this vaccination on the distribution of rotavirus genotypes

The purpose of this study is to monitor diarrheal disease and observe changes after the introduction of the rota vaccine.

The primary objective of the proposed project is to estimate the economic impact of a national rotavirus immunization program in preventing rotavirus diarrhea among Korean children.

Acute gastroenteritis is a common cause of hospitalization in children with significant socioeconomic burden on the health community, we will follow in this observational and analytical study the admitted cases of acute gastroenteritis to the pediatric floor at the Sheikh Ragheb Harb Hospital over a period of summer time to determine the causes, etiologies and epidemiology of Age in a community hospital.

The discovery in 2003 by isolation of amoebas Mimivirus, the world's largest virus at the Research Unit on Tropical and Emerging Diseases in Marseille revealed fascinating information about the definition and evolution of viruses. Its genome encodes about 1,000 proteins. Three other viruses were then isolated from amoebas in this unit:Two other giant viruses, Mamavirus Marseillevirus then, and the first virus a virus, named virophage, which led to highlight the role of amoeba (Acanthamoeba spp. ) such as spawning giant viruses and compounds of bacterial origin or cellular proteins This project focuses on the detection and analysis of new viral agents (viruses and virophages giant amoeba environmental) and their involvement in human pathology. The objectives of this study are observational: detect and document the presence of giant viruses and virophages of amoebae in the faeces of children presenting to the pediatric emergency reception service of the North Hospital in AP -HM with or without clinical evidence of gastroenteritis.

This study aims to determine the contribution of rotavirus infection as a cause of gastroenteritis requiring hospitalization in children younger than 5 years of age. Additionally, a secondary aim will be to determine the genotypes of rotavirus that cause these infections as prevalent in Lebanon.
