Helicobacter pylori infection has been associated with various diseases among them chronic urticaria.ObjectiveTo determine the association between H. pylori infection and allergic and non-allergic chronic urticaria.Material And MethodWe conducted a retrospective, observational and cross-sectional study which included 82 patients of both sexes with a diagnosis of chronic urticaria, aged between 2 and 75 years. Total serum IgE and IgG anti-H. pylori were measured in all participants. Statistical analysis was performed using the chi-squared test with 0.05 significance.ResultsA total of 82 patients, 33 males and 49 females, with a mean age of 36.9 years were studied. H. pylori seropositivity was in 65.2% of allergic patients and 34.8% of non-allergic patients (p = 0.148).ConclusionsWe found no association between chronic allergic urticaria and H. pylori infection.
