RESUMO
Background: It is hypothesized that migraine may be related to inflammatory bowel disease [IBD], therefore in this cross-sectional study we evaluated the prevalence of migraine in patients with IBD
Methods: In this cross-sectional study 80 patients with IBD and 80 patients without IBD referring to a private gastroenterology clinic from May to January 2014 were evaluated regarding the prevalence of migraine, severity of migraine based on Headache Impact Test [HIT-6], and habits related to headache
Results: 160 participants with the mean age of 35 years were evaluated. The prevalence of migraine in the case group was significantly higher than the control [21.3% vs. 8.8%,p=0.027]
Moreover, duration of each attack [hours] in IBD group was significantly higher than the control group [K0.001] while the duration of migraine involvement [months] and number of attacks was higher in the control group [p=0.019 and 0.048, respectively]
Headache other than migraine in the control group was significantly higher than the IBD group [p=0.00l]
Disability in the case group was more than the control group but the difference was not significant. The correlation between the severity of disability related to migraine [based on HIT-6] and severity of IBD [based on Mayo score and Crohn's disease activity index [CDAI]] was not significant [r=0.16, p=0.58]. Moreover the correlation between the duration of IBD and migraine prevalence was not significant [r=-0.14, p=Q. 19]
Conclusion: We found that the prevalence of migraine in patients with IBD is significantly more than normal population. More studies are needed to highlight the correlation between migraine and IBD
