Helicobacter pylori infection and its association with chronic urticaria.
Chronic urticaria (CU) is defined as the occurrence of daily, or almost daily, wheals and itching for at least 6 weeks. It is a common and potentially debilitating skin condition that affects up to 1% of the general population with variable duration, typically several months, but occasionally decades. Chronic idiopathic urticaria (CIU), defined as the occurrence of CU, with no obvious cause, constituting up to 70% of cases. Some studies showed a greater prevalence of H.pylori in chronic urticarial patients as compared to controls . However, a strong evidence linking H.pylori to chronicity of urticarial is lacking. So we will discuss the role of H pylori in development of chronic urticarial
Helicobacter pylori, the most important cause of gastritis and peptic ulcer, recently has been associated with several extra digestive diseases. There have been controversial reports of an elevated prevalence rate of Helicobacter pylori infection in chronic urticaria patients. Furthermore, in some studies remission of chronic urticaria has been reported after eradication of H. pylori. The aim of this report is to evaluate the prevalence of H. pylori infection among chronic urticaria patients and to study the effect of eradication therapy on urticaria symptoms
