[The frequency of demonstration of Campylobacter pylori].

In 376 patients who underwent gastroscopy the presence of Campylobacter pylori by microscopy, bacterial culture and urea test was studied. Additionally, the histological examination of the antral mucosa was performed. The organisms were detected in 47.9% of the biopsy specimens (37.2% in normal endoscopic findings and 70% in duodenal ulcers). Dependence on sex was not found and also no significant difference of Campylobacter pylori detection in patients younger than 45 years compared with those who are older. However there was a strong correlation between the presence of Campylobacter pylori and the histological results (p less than 0.05). In comparison with international literature we found a distinctly lower percentage of positive Campylobacter pylori rate in patients with peptic ulcer; the association between the presence of Campylobacter pylori and the degree of gastritis was confirmed.
