Relationship between Helicobacter pylori and undifferentiated non-granulomatous anterior uveitis.

PURPOSE

The relationship of Helicobacter pylori infection with ocular diseases, including anterior uveitis, has been reported. The objective of this study was to determine the presence of anti-H. pylori IgG antibodies in patients with idiopathic non-granulomatous anterior uveitis and compare the results with a control group.

METHODS

A prospective, comparative, and cross-sectional study was conducted. Patients with idiopathic granulomatous anterior uveitis and a group of control subjects were included. The presence of anti-H. pylori IgG antibodies was determined. The chi-square test was performed for comparative analysis with GraphPad Prism V5.0 software.

RESULTS

Thirty patients with idiopathic non-granulomatous anterior uveitis and 35 control subjects were included. In the determination of anti-H. pylori IgG antibodies, 24 (80%) patients and 19 (54%) control subjects were positive. A significant difference (p = 0.0263) was found between the groups and an odds ratio (OR) of 3.37.

CONCLUSIONS

A direct relationship was found between the presence of anti-H. pylori IgG antibodies and idiopathic non-granulomatous anterior uveitis. An association can be established between idiopathic non-granulomatous anterior uveitis and H. pylori infection, without this being a causal or physiopathogenic relationship.
