Basal and throughout-the-day variations of B-lipotropin (BLPH), B-endorphin (BEP), ACTH and cortisol plasma levels were studied in seven prepubertal children who had been affected by common migraine for periods of 6-26 months and in six healthy volunteers. Despite normal cortisol concentrations, children with migraine show higher BLPH (15.1 +/- 2.7 fmol/ml, M +/- SE), ACTH (25 +/- 2.7) and BEP (9.1 +/- 1.1) levels than controls. In both groups of children, evening values (8 p.m.) were significantly lower than morning values, but in migraineurs the decrease of the three peptides was less. The raised proopiocortin-related peptide plasma levels found in children suffering from migraine cannot be explained at present, although the discomfort experienced by the patients may create a situation of chronic stress which could explain such a finding. Whatever the explanation is, these findings differentiate prepubertal migraine from the most severe forms of headache occurring in adult life where lower than normal opioid levels have been demonstrated.

Abstract

Basal and throughout-the-day variations of B-lipotropin (BLPH), B-endorphin (BEP), ACTH and cortisol plasma levels were studied in seven prepubertal children who had been affected by common migraine for periods of 6-26 months and in six healthy volunteers. Despite normal cortisol concentrations, children with migraine show higher BLPH (15.1 +/- 2.7 fmol/ml, M +/- SE), ACTH (25 +/- 2.7) and BEP (9.1 +/- 1.1) levels than controls. In both groups of children, evening values (8 p.m.) were significantly lower than morning values, but in migraineurs the decrease of the three peptides was less. The raised proopiocortin-related peptide plasma levels found in children suffering from migraine cannot be explained at present, although the discomfort experienced by the patients may create a situation of chronic stress which could explain such a finding. Whatever the explanation is, these findings differentiate prepubertal migraine from the most severe forms of headache occurring in adult life where lower than normal opioid levels have been demonstrated.
