[Inflammatory changes in the gastric mucosa of patients with idiopathic non-ulcer dyspepsia and the effect of colloid bismuth treatment on the course of inflammation].

The studies were aimed at the assessment of the coexistence of non-ulcer dyspepsia with chronic gastritis and Campylobacter pylori infection, and of the effect of therapy with De-Nol on the course of such disease. The studies involved 50 patients with non-ulcer dyspepsia. Prior to and after the treatment with De-Nol samples of the mucosa collected from the antrum and corpus of the stomach have been examined histologically with urease test indicating C. pylori infection. Chronic gastritis of the antral mucosa membrane and/or mucosa of the corpus of the stomach has been found in 36 patients, and normal mucosa in 14 patients. Therapy with De-Nol produced statistically significant improvement. Totally histological improvement has been noted in 77.1% of patients with inflammation of the antral mucous membrane and in 64.3% of patients with inflammation of the corporeal gastric mucosa. Campylobacter pylori has been eradicated in all patients with chronic gastritis. De Nol eliminates or significantly lowers an inflammation in the antrum and/or corpus of the stomach. Its action is related to the eradication of Campylobacter pylori infection.
