Characteristics of Eosinophilic Gastritis, Enteritis, and Colitis in a Multi-Site Cohort
Eosinophilic EsophagitisEosinophilic Gastritis2 moreThe purpose of this study is to investigate features of patients with Eosinophilic Gastrointestinal Disorders (EGIDs) other than Eosinophilic Esophagitis (EoE) alone, including Eosinophilic Gastritis (EG), Eosinophilic Gastroenteritis (EGE), and Eosinophilic Colitis (EC).
Evaluation of Immunochromatographic Tests for Campylobacter Detection in Stools
GastroenteritisFor a long time, culture was the only way to detect Campylobacter. It appears that rapid immunochromatographic tests (ICT) have detected more positive cases compared to culture, ELISA and molecular tests. The aim of our study is to evaluate the specificity of the ICT which are really interesting tools to use since they allow a diagnosis in about 15 min, in comparison to different methods of detection even serology.
Hospital-based Surveillance of Rotavirus Gastroenteritis in Young Taiwanese Children
Rotavirus GastroenteritisYoung Taiwanese ChildrenRotavirus remains among the leading causes of pediatric gastroenteritis requiring hospitalization in the world. Surveillance studies revealed that more than 90% of the global circulating rotavirus strains were predominated by several major genotypes. Clinical trials and post-marketing studies have demonstrated that the currently available rotavirus vaccine can provide sufficient protection against strains of the prevalent genotypes. However, the emerging strains with new genotypes were increasingly reported in the past decade, an ongoing surveillance of the strain changes is needed in the regions where the pediatric population is either fully or partly immunized. In this project, the investigators will setup a hospital-based gastroenteritis surveillance network by incorporating 8 major hospitals in northern, central, southern and eastern Taiwan. From 2013 to 2015, children aged 5 years or younger hospitalized to one of the 8 sentinel hospitals due to acute gastroenteritis will be screened for rotavirus infection, and viral proteins 7 [VP7] (G type) and viral proteins 4 [VP4] (P type) genotypes of rotavirus will be determined for each infected case. The demographics and clinical manifestations of study subjects will also be collected and analyzed. Through this project, the investigators will be able to detect emerging genotypes of rotavirus and delineate the strain distribution during the two years of study in Taiwan. The investigators can also have more comprehensive understanding of the epidemiology of rotavirus regarding to the incidence, disease characteristics, temporal and geographic variations of severe rotavirus gastroenteritis in Taiwanese children. Results from this project will provide valuable information for future implementation of mass immunization against rotavirus in Taiwan.

InfectionsRotavirusThe aim of this study is to monitor any impact in the change from the lyophilised formulation to the liquid formulation of the Rotarix™ vaccine on hospitalisations for rotavirus gastroenteritis. This is planned to be assessed by comparing trends of hospitalisations due to laboratory confirmed rotavirus gastroenteritis in children <=5 years of age, before and after introduction of the liquid formulation of the vaccine in Belgium.

Optimising Rotavirus Vaccine in Aboriginal Children
Viral Gastroenteritis Due to RotavirusAustralian Indigenous children, particularly those living in remote communities, suffer a disproportionately high burden of rotavirus gastroenteritis disease. Despite the introduction of rotavirus vaccine into the Northern Territory (NT) Immunisation Schedule in 2006, the rate of hospitalization for rotavirus in NT Aboriginal children < 5 years continues to be high, and the rate ratio of rotavirus hospitalisations for Indigenous versus non-Indigenous children has actually increased. The reasons for sub-optimal vaccine response are not completely understood, but both reduced vaccine immune responses and low vaccine coverage are likely to be important factors. The purpose of this study is to determine if Aboriginal children who receive an additional dose of RV1 between the ages of 6 and 12 months, will have an increase anti-rotavirus serum IgA seroconversion and decreased medical presentations with gastroenteritis in the first three years of life, compared to those who receive placebo.
