MULET PEREZ, Agustín M et al. Chronic Antral Gastritis for Helicobacter pylori in Patients with and without Duodenogastric Reflux . CCM [online]. 2014, vol.18, n.1, pp. 65-78. ISSN 1560-4381.

Introduction: the chronic antral gastritis for Helicobacter pylori (H pylori) and duodenogastric reflux disorders are frequent affections that can coexist. The possible influence of the duodenogastric reflux disorders on chronic antral gastritis for Helicobacter pylori is a controversial theme. Objective:  to estimate the histopathological behavior of the chronic antral gastritis for H. pylori according to the presence or not of duodenogastric reflux. Methods: a control case study was carried out. The universe comprised the total of patients attended during August 2011- August 2012 in Gastroenterology Service of the Teaching Hospital of Holguín, with endoscopy and gastric antral diagnostic biopsy of chronic antral gastritis and infection by H. pylori. Two samples were selected: a study group with duodenogastric reflux (25 patients, 34.7%) and a control group without duodenogastric reflux (47 patients). Results: the active forms (80%), bigger degrees of severity lesion (68%) and of Helicobacter pylori's density of colonization (56%) predominated in the study group without significant differences comparing to the control group (P< 0.05). Conclusions: there were no synergetic and antagonistic relations between the infection for Helicobacter pylori and the flowed back material in relation to the harmful action on the gastric mucosa and the magnitude of the colonization for the bacterium.
