[Chronic urticaria and Helicobacter pylori].
OBJECTIVE
We intended to analyze the influence of Helicobacter pylori eradication on the clinical evolution of patients with chronic idiopathic urticaria.


METHODS
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.
