[Prognosis of bleeding from duodenal ulcers].

Clinical and pathogenetic findings on 147 patients with duodenal ulcer (DU) and 29 patients with DU complicated by ulcerogenic bleeding were compared. This allowed to single out significant criteria for prediction of development of bleeding in such patients: male sex freguent seasonal exacerbations, hereditary load, location of the ulcer at the back wall of the duodenal bulb, negative atropine test, HLA-phenotype B35, A2 A3, A2 AX. High acidity and large sixe of DU were hot prognostically independent. The importance of complex approach in solution of prognostic problems is emphasized.
