Abstract

Background: Recent studies have shown a positive correlation between Helicobacter pylori infection and migraine headache. The aim of this study was to evaluate the role of H. pylori infection in migraine headache with (MA) and without aura (MO).Methods: This is a case-control study containing information on 84 patients (including MA, MO) and 49 healthy individuals. The enzyme-linked immunosorbent assay (ELISA) test was used to measure immunoglobulin G (IgG,) immunoglobulin M (IgM) titer in two groups. Headache severity was evaluated according to Headache Impact Test (HIT6) questionnaire.Results: Mean ± SD of IgM antibody in Migrainous patients 26.3 (23.1) showed significantly difference with control group 17.5 (11.2) (P = 0.004). In addition, the mean ± SD HIT6 in Migrainous patients differed significantly between MA and MO groups 65.5 (4.7), 54.9 (5.3) respectively, P < 0.001). The only significant correlation was found for IgG antibody and HIT6 in MA patients (r = 0.407, P = 0.011) and MO group (r = 0.499, P = 0.002). The risk of migraine occurrence in patients did not significantly associate with the level of IgG and IgM antibodies.Conclusion: The results give a hope that definite treatment and eradication of this bacterium could be a cure or to reduce the severity and course of migraine headaches.
