title: [Helicobacter pylori].
abstract: Of great impact has been the studies of Helicobacter pylori and its association with illnesses of the stomach and duodenum. We have reviewed and outlined the pathological mechanisms by which H. pylori causes illness, the results of experiments in animals, the different methods of diagnosis (invasive and noninvasive). We also have detailed the association of H. pylori infection in different gastric conditions such as chronic active gastritis and peptic ulcer disease and the results obtained after antimicrobial treatment. We also have reported the results of Peruvian patients studied over the last 6 years by the Gastrointestinal Working Group of the Universidad Peruana Cayetano Heredia and the Johns Hopkins University. These patients were of widely varying age, socioeconomic level and came from 3 different regions of Peru, we also have explained the result we have obtained in the treatment of this infection using regimens employing mono or triple therapy.
