Background and objective: We intended to analyze the influence of Helicobacter pylori eradication on the clinical evolution of patients with chronic idiopathic urticaria.
Patients and method: The evolution of dermatological symptoms after eradication was studied in a group of 55 patients previously diagnosed with chronic idiopathic urticaria who were infected by Helicobacter pylori.
Results: There was a partial or complete improvement in 74.6% (CI 95%, 61-85%) of studied patients. We could not demonstrate a statistically significant influence of sex, age or endoscopic lesions on the clinical evolution of urticaria after eradication.
Conclusions: These results suggest a possible usefulness of Helicobacter pylori eradication in some patients with chronic idiopathic urticaria. Controlled and randomized studies are necessary to confirm it.
