Abstract

The infectious factor like Helicobacter pylori (HP) has been thought to trigger the vicious circle of chronic idiopathic urticaria (CIU), therefore its eradication could modify the course of the disease. To reveal the influence of HP eradication on CIU clinical course. Sixty-four CIU patients, receiving fexofenadine, as the basic treatment, took part in the research, divided into 3 groups: HP patients treated by eradication, HP patients receiving placebo, and patients without bacteria. Gastroscopy, urease test and histopathology were done to detect HP. Patients with HP were randomized and received eradication treatment or placebo. The efficacy of eradication was checked after 6 weeks by means of another gastroscopy, urease test and histopathology. In the 6th week and in the 4th and 6th month after eradication, the symptoms were evaluated basing on the score symptom scale. Helicobacter pylori did not occur more frequently in CIU patients than in the healthy population. A statistically significant clinical improvement of CIU symptoms was observed in the 6th week after eradication as compared to the group receiving placebo (p = 0.02) and patients who were not infected (p = 0.02). Further observation in the eradicated patients grou...Continue Reading
