Key clinical point: Very low-quality evidence showed that serum pituitary adenylates cyclase–activating polypeptide (PACAP) levels were lower in adults with a longer history of migraine.
Major finding: Serum levels of PACAP were inversely associated with history of migraine duration in adults with migraine (summary r −0.35; P < .01). It was also seen that serum PACAP levels were higher during the ictal vs interictal period in both adults and children with migraine (standardized mean difference 0.41; 95% CI 0.17-0.66).
Study details: Findings are from a meta-analysis of eight observational studies including 674 patients with migraine and 371 control individuals without migraine.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
