Justification of Genetic Factors for Predicting the Risk of Acute Bleeding in Peptic Ulcer Disease.

PAI genotyping for the G43A and 4G/5G polymorphisms was performed in 60 patients with peptic ulcer disease: 12 with an uncomplicated ulcer, 5 with perforation, the rest with ongoing bleeding. Fourteen patients had recurrent bleeding. The 5G/5G and G43A genotypes were not detected in patients with uncomplicated ulcers.
