Prevalencia de gastritis causada por helicobacter pylori en pacientes con antígeno negativo en examen de heces en el Hospital Teodoro Maldonado Carbo, en el periodo junio 2016 – diciembre 2016.

Abstract

Introduction: Helicobacter pylori is found in half the world population. Its prevalence shows high variability according to geographic region, ethnicity, race, age, and socioeconomic factors. It is high in developing countries and lowest in the developed world. In general, however, in recent years there has been a declining trend in the prevalence of H. pylori in many parts of the world. It is one of the fundamental causes of gastritis, peptic ulcer and duodenal ulcer and is considered to increase the propensity to gastric cancer. Objective: To observe the differences in patients with chronic gastritis with presence and absence of H. pylori. Material and methods: A cross-sectional observational study was conducted at the Teodoro Maldonado Carbo Hospital in Guayaquil, Ecuador, between June 2016 and December 2016, with gastric pathologies diagnosed previously stool examination and high endoscopy. Results: Predominated female sex with eighty-seven patients (65%). Fecal examination revealed that the presence of H. pylori was the most frequent diagnosis represented by 90%. There was a relationship between the consumption of NSAIDs and the presence of gastritis, which one hundred two patients (76%) consumed prior to diagnosis. Conclusion: The fourth decade of life was imposed as the most frequent age range in relation to the presence of H. pylori. The prevalence of positive biopsies for Helicobacter pylori observed in symptomatic patients with negative antigen corresponds to 10%. This test has a sensitivity of 89-98%, accompanied by a specificity of 90%.
