Helicobacter pylori infection and risk of peptic ulcer among cirrhotic patients.

There is a higher prevalence of peptic ulcer disease in cirrhotic patients than in the general population. Whether Helicobacter pylori is a risk factor for peptic ulcer in cirrhosis remains controversial. The aim of this study was to determine whether there is a significant correlation between H.pylori infection and peptic ulcer in liver cirrhosis. In a cross-sectional study, 49 cirrhotic patients underwent upper gastrointestinal endoscopy and 75 controls (health examinees) without liver disease were also examined by endoscopy. The presence of H. pylori was assessed by culture, histologic findings and rapid urease test of gastric antrum biopsy specimens. Thirty of the 49 (61%) cirrhotic patients had peptic ulcers as compared to 24 of the 75 (32%) controls. The frequency of H. pylori in the antrum in the cirrhotic group was significantly lower than in the control group (39% vs 69%). The presence of H. pylori was more frequent in control patients with gastric (75%) and duodenal ulcers (95%) than nonulcer control patients (59%) whereas the difference between patients with peptic ulcer and nonulcer (40% vs 37%) was not significant in cirrhotic patients. H. pylori was identified in 40% of the cirrhotic patients with duodenal ulcers compared with 95% of controls with duodenal ulcers (p < 0.05). Nevertheless, this difference was not significant among patients with a gastric ulcer between the two groups (40% vs 75%). There was no significant difference in the frequency of H. pylori infection among nonulcer patients between the cirrhotic and control groups (37% vs 59%). In conclusion, we found no evidence to substantiate an etiologic role of H. pylori in the development of a duodenal ulcer in cirrhotic patients.
