[The diagnosis of Helicobacter infections in patients with gastric and duodenal peptic ulcers]. / Diagnostika khelikobakternoi infektsii u bol'nykh iazvennoi bolezn'iu zheludka i dvenadtsatiperstnoi kishki.

The results of the study of 33 patients having gastroduodenal peptic ulcer, with 9 of them subjected to surgical treatment, are presented. The diagnostics of Helicobacter infection was made with the use of bacteriological and biochemical assays. The study revealed that in the overwhelming majority of cases peptic ulcer was associated with the presence of H.pylori, and the most informative method for the diagnostics of H.pylori infection was the bacteriological study of biopsies from the pyloric antrum characterized by the highest degree of massive contamination. The determination of ammonia concentration by biochemical assay with the use of Aerotest was most suitable for the diagnostics of H.pylori infection in patients with a short history of peptic ulcer.

[Comorbid gastric and duodenal changes in chronic hepatitis C in young patients]. / Soputstvuiushchie izmeneniia v zheludke i dvenadtsatiperstnoi kishke pri khronicheskom gepatite C u lits molodogo vozrasta.

Characteristics of the gastroduodenal zone, frequency of gastric mucosa contamination with Helicobacter pylori (HP) were studied in young patients with chronic hepatitis C (CHC). Affections of the stomach and the duodenum were encountered in 76.3% of CHC patients. They run, as a rule, latently and in most cases (80%) are associated with HP. Concurrent diseases of the upper gastroduodenal tract seem to have only a minor impact on the course of HCV infection. Therefore, it is better to avoid eradication of HP in young patients with CHC.
