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.

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
