Summary
We prospectively studied the prevalence of lupus anticoagulant, anticardiolipin antibodies
(aCL) and various haemostatic parameters in 71 patients with migraine and compared
the results with a control group of 32 subjects with back pain never having experienced
migraine. The patients with migraine were divided into two groups: group I with migraine
without (n = 18) and with aura lasting less than 60 min (n = 24) and group II with migraine with prolonged aura or migrainous infarction (complicated
migraine, n = 29). The following results were obtained: a) no difference in aCL positivity was
noted between migrainous patients and controls and between common migraine and complicated
migraine patients and b) no statistically significant difference in haemostatic parameters
(except for thrombin-antithrombin III complexes) was found between the two groups
of migraine and between aCL positive and negative migrainous patients. These data
suggest that anticardiolipin antibodies are not involved in the pathogenesis of migraine
complications.
