<i>Helicobacter pylori</i> infection in patients with chronic urticaria: correlation with pathologic findings in gastric biopsies

Abstract

Helicobacter pylori may have a role in the exacerbation of urticarial symptoms, even though it is not involved directly in its etiology, and its eradication may lead to symptom improvement in a considerable number of infected urticaria patients. The severity of symptoms is dependent on the density of bacterial infection and the intensity of inflammatory infiltrate in the gastric biopsy.
