Helicobacter pylori infection: prevalence in chronic urticaria patients and incidence of autoimmune urticaria (study in Dr. Cipto Mangunkusumo Hospital, Jakarta). Acta Medica Indonesiana. 2007 Oct-Dec; 39(4): 157-62http://imsear.searo.who.int/handle/123456789/47134AIM: To determine the prevalence of Hp infection in patients with chronic urticaria (CU) and to evaluate the result of autologous serum skin test (ASST) in CU patients with Hp infections. METHODS: In this cross-sectional study, 16 patients with chronic urticaria and 16 non-urticaria volunteers were investigated (matched for age and sex). All subjects were examined for Hp infection with the 13C-urea breath test. Autologous serum skin test was performed in patients with proven Hp infection. RESULTS: Helicobacter pylori was detected in 12.5% of patients and 0% of the control group. There was no significant difference between the two groups (p = 0.484 using Fisher exact test). Autologous serum skin test was positive in 1 of 2 CU patients with Hp infection. CONCLUSION: In this study, there was no significant difference in the seroprevalence of Hp infection between CU patients and controls. Autologous serum skin test was positive in 1 of 2 CU patients with Hp infection.engAdolescentAdultAgedAutoimmune Diseases --bloodChronic DiseaseCross-Sectional StudiesEducational StatusFemaleHelicobacter Infections --bloodHelicobacter pylori --isolation & purificationHumansIncidenceIndonesia --epidemiologyMaleMiddle AgedSeroepidemiologic StudiesUrticaria --bloodJournal Article
