Does quantitative serologic testing for Helicobacter pylori predict peptic ulcer disease in cirrhosis?

Helicobacter pylori infection and peptic ulcer disease in patients with liver cirrhosis

BACKGROUND/AIMS

We investigated the prevalence and relationship of peptic ulcer disease and Helicobacter pylori infection to liver cirrhosis.

METHODS

We examined 288 patients with liver cirrhosis, 322 patients with non-ulcer dyspepsia, and 339 patients with peptic ulcer disease. Rapid urease test and Wright-Giemsa staining were used for diagnosis of H. pylori infection.

RESULTS

The prevalence of peptic ulcer disease in patients with cirrhosis was 24.3%. The prevalence of peptic ulcer disease in patients with cirrhosis divided into Child-Pugh classes A, B, and C was 22.3%, 21.0%, and 31.3%, respectively (p > 0.05). The prevalence of H. pylori infection in the patients with cirrhosis, non-ulcer dyspepsia, and peptic ulcer without chronic liver disease were 35.1%, 62.4%, and 73.7%, respectively (p < 0.001). The prevalence of H. pylori infection did not differ depending on whether there was peptic ulcer (35.6%) or not (34.9%) in patients with liver cirrhosis (p > 0.05). The prevalence of H. pylori infection in patients with hepatitis virus-related liver cirrhosis and in the patients with alcohol-related liver cirrhosis was 42.5% and 22.0%, respectively (p < 0.001). The prevalence of H. pylori infection in patients with Child-Pugh classes A, B, and C liver cirrhosis was 51.5%, 30.5%, and 20.0%, respectively (p < 0.001).

CONCLUSIONS

Factors other than H. pylori may be involved in the pathogenesis of peptic ulcer disease in the setting of liver cirrhosis.

Helicobacter pylori is a risk factor for peptic ulcer disease in cirrhotic patients. A meta-analysis

BACKGROUND

Peptic ulcer disease is highly prevalent in cirrhosis, and ulcer complications are a major cause of morbidity in these patients. Helicobacter pylori infection is considered the chief aetiological factor of ulcer disease. However, in cirrhotic patients the role of H. pylori in the pathogenesis of peptic ulcer remains uncertain.

AIM

To evaluate the evidence of the pathogenic role of H. pylori infection in peptic ulcer disease in patients with cirrhosis.

MATERIALS AND METHODS

An extensive MEDLINE search of the literature was performed. Studies reporting the prevalence of H. pylori infection in cirrhotic patients with and without ulcers were selected. Meta-analysis was conducted using RevMan 4.0.3. Pooled odds ratios were calculated for each comparison, using a fixed model analysis.

RESULTS

The search identified seven studies with a total of 976 patients with cirrhosis (275 cases with ulcer disease and 701 controls). The prevalence of H. pylori infection in patients with peptic ulcer disease was higher than in those without. The pooled odds ratio was 2.70 (95% CI, 1.91-3.82). H. pylori infection was associated more or less equally with duodenal and gastric ulcers.

CONCLUSION

H. pylori infection increases the risk of peptic ulcer disease in patients with cirrhosis.
