Estudio epidemiológico de infección por Helicobacter pylori en el cono urbano bonaerense / Epidemology of helicobacter pylori infection in the province of Buenos Aires

Hemos planteado el presente trabajo, teniendo en cuenta los siguientes aspectos: describir las características epidemiológicas y demográficas en la población estudiada y además caracterizar especialmente los factores higiénicos, sanitarios y culturales que por su heterogeneidad, tuvieron influencia en la capacidad de infección por el Helicobacter Pylori

Nuevo método para detección de infección y erradicación del Helicobacter pylori (Hp) por determinaciòn de antígenos en meteria fecal / A new method for detection H. pylori infection and erradication by stool antigen test

Nowadays technics for Helicobacter pylori detection in stools like culture, and PCR, are expensive and difficult to perform. The aim of this study was to evaluate ELISA test efficacy for detection of H. Pylori antigens in stools comparing this results with standarized technics like histology (Giemsa), ureasa test and UBT C 14. 26 patients were evaluated in this study, ages between 15-75 with upper gastrointestinal symptoms; all of them required gastroduodenal endoscopy, status H. Pylori was determined with methods upon mentioned. 24 hours after endoscopy H. Pylori antigens in stools with the technique Premier Platinum Htsa, Elisa were determined. The detection of H. Pylori antigens in stools accurately identified active H. Pylori infection. The performance characteristics of this non-invasive method was similar in sensibility and specificity to conventional tests
