Rapid urease test was done for all the patients and a gastric biopsy sample was obtained from the antrum of the stomach and sent to the pathology department. Sections made from the gastric biopsy sample were stained with H and E and Giemsa stain. Sections were then evaluated for the presence of H. pylori.
Results: In the 150 alcoholic patients included in the study, prevalence of H. pylori was 76%. The age and the gender did not play a role in the H. pylori infection. It was observed in the study that the prevalence of H. pylori infection increased with the increase in frequency, duration, amount of alcohol intake with a statistically significant p value.
