Lack of association between antiphospholipid antibodies and migraine in children.

Anticardiolipin antibodies are found frequently in those suffering from migraine, but it is not clear if this association is real or coincidental. Moreover, there are no data on the prevalence of anticardiolipin antibodies in children. In this study, 40 patients were divided into two groups according to the type of migraine: group I included 22 cases (15 females and 7 males, mean age±SD 13.7±8.9 years) suffering from migraine with and without aura; group II consisted of 18 children (10 females and 8 males, age 14.7±6.9 years) having migraine with prolonged aura or migrainous infarction, also called complicated migraine. We studied two groups of children as controls: a group of 35 children (25 females and 10 males, mean age 13.9±7.1 years) with juvenile chronic arthritis (group III) and a group of 40 healthy sex- and age-matched children who did not suffer from migraine or any other neurological disease (group IV). No statistically significant differences in levels of anticardiolipin antibodies were found between group I and II and controls. Our data demonstrate that, in children with migraine, anticardiolipin antibodies are not more frequent than in healthy controls, and suggest that anticardiolipin antibodies are not implicated in the pathogenesis of migraine.
