Résumé :

Epigastric pain is a common complaint in rural Kivu, eastern Zaire, an area with high incidence of peptic ulcer and gastric cancer. It has recently been recognized that Helicobacter pylori is the causative agent of chronic type B gastritis, and that it is also strongly associated with duodenal ulcer. This paper reports the endoscopic, histological and bacteriological findings in all dyspeptic patients presenting to the Fomulac hospital in Katana over a 7-month period. Of 324 patients, 43 had duodenitis, 38 duodenal ulcer, 23 carcinoma of the stomach, and five gastric ulcer. Chronic active gastritis was found in 93% of the patients, and of these, 90% were colonized with H. pylori. The prevalence of H. pylori did not differ with gender for any particular age group, nor with respect to smoking, drinking, dietary habits, socioeconomic status, ethnic origin, or area of residence urban or rural. Nine out of 10 teenagers were already infected with H. pylori, reflecting the early prevalence of H. pylori during life in this population. High prevalence of gastritis and H. pylori has been found in other studies throughout Africa, even in asymptomatic populations and also in areas with a low incidence of peptic ulcer.
