Background
In the last two decades the relation between chronic Helicobacter pylori (HP) infection and
migraine has been studied, but the results of these studies are controversial.
Objective
The aim of this study was to determine whether current or previous exposure to HP infection
is a risk factor in women with nonmenstrual migraine (NMM) without aura, a concise subgroup
in which environmental factors are dominant.
Patients and methods
A total of 24 women, with ages ranging from 19 to 60 years, affected by NMM without aura
were evaluated in comparison with 24 control women, with ages ranging from 20 to 59 years,
without any history of primary headache. In both cases and controls HP infection was evaluated
by detection of HP antibodies in serum and HP antigen in stool.
Results
The prevalence of HP infection was nonsignificantly higher in the migraineurs without aura
compared with controls (P = 0.24 and 0.33). Regarding the intensity, duration, and frequency
of attacks of migraine no differences were detected between the two groups.
Conclusion
Our findings do not support HP infection to be a risk factor for NMM without aura.
