Lipoprotein a levels in pediatric migraine

Abstract

The purpose of this study was to examine the lipoprotein (a) [Lp(a)] levels in children with migraine to see a possible relationship between migraine and stroke via high Lp(a) levels. Plasma levels of Lp(a) were determined in 63 patients and age-matched control subjects. The mean age in the control group was 10.57 ± 3.63 years and 11.51 ± 3.19 years in the migraine patient group. The mean Lp(a) levels in control group were 10.36 ± 10.41 ng/mL and 17.09 ± 12.12 ng/mL in migraine group (P < 0.05). The median Lp(a) level in the control group was 49.38 ng/mL and was 77.62 ng/mL in the migraine group (P < 0.05). Twelve patients (19%) had Lp(a) levels of >30 ng/mL in the migraine group and 4 (6.3%) in the control group (P < 0.05). Several prothrombotic factors related to an increased risk of stroke have been studied in migraine patients. It has recently been reported that high Lp(a) concentrations represent a risk factor for migraine, thus establishing a novel plausible link between migraine and stroke. The current study suggests evidence of high Lp(a) concentrations in childhood migraine; perhaps a novel link exists between migraine and stroke.
