[Helicobacter pylori infection in 755 patients with digestive complaints: Pasteur Institute, Morocco, 1998-2007].

We determined the prevalence of Helicobacter pylori infection in 755 patients with digestive complaints identified from laboratory records at the Pasteur Institute, Morocco from 1998 to 2007. Epidemiological factors and gastrointestinal conditions associated with this infection were also studied. All patients underwent endoscopy and diagnosis was by histology examination. The prevalence of H. pylori infection was 69%. The difference in prevalence between the age group 40-50 years and other age groups was statistically significant; gender had no significant association. H. pylori infection was found in 92% of chronic gastritis cases. The prevalence of H. pylori was significantly higher in the antrum (73%) than in the corpus (21%) and the pylorus (6%).
