Randomized Controlled Trial Comparative Study Clinical TrialChronic urticaria and Helicobacter pylori.
Chronic urticaria can result from multiple causes. A number of factors have been identified that can appear to be important in the pathogenesis of individual cases, including intolerance to food, drugs, some internal diseases and some infections. Recently a possible relationship between chronic urticaria and Helicobacter pylori has been suggested. ⋯ Three patients in the eradication therapy group showed complete remission of urticaria after 12 months of follow-up as compared with 1 patient in the control group. Twenty blood donors out of 46 were IgG anti-Helicobacter pylori positive. In conclusion, our data show that the prevalence of Helicobacter pylori infection is high in chronic urticaria patients, but eradication of the bacterium does not appear to influence the skin disorders nor the symptoms.
