Abstract: Background: Some studies have suggested an association between migraine and inflammatory bowel disease. We determined migraine prevalence in a cohort of patients with inflammatory bowel disease.
Methods: Patients with inflammatory bowel disease aged 18?65 years were interviewed using an ad hoc headache questionnaire. Those who admitted a history of headache in the last year answered the three questions of the ID-Migraine questionnaire. Those who answered "yes" to the three of them were classified as "definite" and those who answered "yes" to two were classified as "probable" migraine.
Results: We interviewed 283 patients with inflammatory bowel disease. Of these, 176 (62.2%) had headache. Fifty-nine (20.8%; 95% CI 16.3?26.0%) met migraine criteria either definite (n?=?33; 11.7%; 95% CI 8.2?16.0%) or probable (n?=?26; 9.2%; 95% CI 6.1?13.2). When divided by gender, 12 men (9.6%; 95% CI 5.1?16.2%) and 47 women (29.8%; 95% CI 22.8?37.5%) met migraine criteria. The prevalence of migraine was increased in inflammatory bowel disease patients from the current cohort (20.8%) versus that reported for our general population for the same age group (12.6%; p?0.0001). These differences remained significant in female inflammatory bowel disease patients (29.8% versus 17.2% in our general population; p?0.0001), but not in males (9.6% in inflammatory bowel disease vs 8.0%; p?=?0.30). Seventeen patients with inflammatory bowel disease (6.0%; 95% CI 3.54?9.44%) fulfilled chronic migraine criteria. There were no differences in migraine prevalence by inflammatory bowel disease subtypes.
Conclusion: Migraine prevalence, including chronic migraine, seems to be increased in patients with inflammatory bowel disease. The fact that this association was stronger for women suggests an influence of sex-related factors.
