Beta-endorphin concentrations in the peripheral blood mononuclear cells of migraine and tension-type headache patients

Levels of beta-endorphin in peripheral blood mononuclear cells have been studied as a new approach to investigating opioid tone in migraine and tension-type headache. Sixty-one patients with migraine without aura, 39 with migraine with aura and 23 with episodic tension-type headache were compared with 37 healthy controls. Peripheral blood samples were taken from patients not enduring headache attacks and not undergoing prophylactic treatment. A significant reduction in peripheral blood mononuclear cell beta-endorphin concentrations was observed in migraine patients with and without aura, but not in tension-type headache patients. Altered transmitter modulation to peripheral blood mononuclear cells may be the cause of this alteration, which could be part of a more diffuse opioid system derangement in migraine subjects.

Beta-endorphin levels are reduced in peripheral blood mononuclear cells of cluster headache patients
Female; Humans; Male; Adult; Reference Values; beta-Endorphin/blood; Cluster Headache/blood; Monocytes/metabolism
Opioid system hypofunction has been postulated in cluster headache (CH) on the basis of reduced opioid levels found in the cerebrospinal fluid (CSF). In this study beta-endorphin levels were monitored in the peripheral blood mononuclear cells of 65 episodic CH patients (32 in remission and 33 in cluster period) and 50 healthy controls. Beta-endorphin levels were significantly lower than controls in CH patients experiencing both phases of the illness (ANOVA, p < 0.0001). The persistence of this abnormality during pain-free remission suggests a primary alteration in the regulation of beta-endorphin in peripheral blood mononuclear cells. We speculate that these findings reflect reduced CNS levels of beta-endorphin in CH.
