Helicobacter pylori and rosacea.

Recent reports have suggested an increased prevalence of Helicobacter pylori infection in patients with rosacea, with some evidence of dermatological improvement in patients treated with antibiotics for this infection. Our study investigates the prevalence of H. pylori infection in rosacea patients in Kerman. Serological examination was done for 29 patients with classical identification of rosacea using the enzyme-linked immunosorbent assay IgG antibody method. Comparison of antibody titres with those of a control group revealed that the prevalence of positive serological tests for H. pylori was significantly higher in the test group. This supports the suggestion of some form of relationship between rosacea and H. pylori infection, though further investigations with larger sample sizes are required for a definite conclusion.
