title: [Prevalence of Helicobacter pylori infection in Tananarive, Madagascar].
abstract: During a 8-month period, Helicobacter pylori infection has been studied in 140 patients who presented upper gastrointestinal symptoms. Helicobacter pylori was searched in antral biopsy specimens using standard bacteriological methods (Gram-staining, urea-test, culture) and histological staining techniques (hematoxylin-eosin-saffron, undifferentiated Giemsa). The global prevalence of H. pylori infection was 59%. The prevalence rates did not seem to differ with age and sex but H. pylori infection was significantly more frequent in patients with an active duodenal ulceration (30 of 41) compared with those with a normal endoscopy (21 of 47) (p < 0.02).
