Key clinical point: Patients with rheumatoid arthritis (RA) had a higher risk for migraine than those without RA, irrespective of the RA serologic status.
Major findings: Patients with vs without RA had a 1.2-fold higher risk for migraine (adjusted hazard ratio (aHR), 1.21; 95% CI, 1.17-1.26). Both seropositive RA (aHR 1.20; 95% CI, 1.15-1.24) and seronegative RA (aHR, 1.26; 95% CI, 1.20-1.34) were associated with an increased risk for migraine. However, the risk was not significantly different between patients with seropositive RA and those with seronegative RA.
Study details: This longitudinal retrospective cohort study included 42,674 patients with RA (29,774 with seropositive RA and 12,900 with seronegative RA) and 213,370 age- and sex-matched control individuals without RA. Overall, 22,294 new migraine cases were reported during a mean follow-up of 4.4 years, following a 1-year lag period.
Disclosure: The study did not receive any funding. The authors declared no conflicts of interest.
