Concentration of beta- Endorphin in Plasma of Patients with Stress - Associated Dermatoses

Abstract

BACKGROUND: Stress has long been known to play a role in many dermatologic disorders and can affect the onset and course of the disorder in some patients. Stress-induced exacerbation or onset of symptoms has been reported in chronic urticaria, alopecia areata, herpes simplex, herpes zoster, and psoriasis vulgaris, and these diseases can be classified as stress-associated dermatoses. Beta beta-endorphin is one of the most important mediators of stress, which is known to be generated upon stimulation of the pituitary-adrenal axis, and its secretion increases during periods of stress.
OBJECTIVE
In order to see wheather beta-endorphin might be related to the onset or recurrence of stress-associated dermatoses, we compared the plasma concentration of beta-endorphin in patients with stress-associated dermatoses with those of healthy subjects.
METHODS
The concentration of beta-endorphin. In sera was quantified by radioimmunoassay, using the INCSTAB 125I RIA Kit for plasma beta-endorphin, Each patient was asked to indicate if they believed that their skin problem began after an important stressful event in their lives.
RESULTS
There was no significant difference in plasma beta-endorphin levels between patients with chronic urticaria, alopecia areata, herpes simplex, and herpes zoster and healthy subjects(p>0.05), whereas in patients with psoriasis vulgaris, plasma level of beta-endorphin was significantly increased (p<0.001). There was no relationship between the stressful events and plasma beta-endorphin concentrations.
CONCLUSIONS
The plasma beta-endorphin level is not correlated with the onset or recurrence of stress-associated dermatoses such as chronic urticaria, alopecia areata, herpes simplex, and herpes zoster. The increase in beta-endorphin in psoriasis vulgaris is more likely that this peptide is generated by the lymphocyte infiltrated in the skin and/or by lymphocytes when they recirculate rather than by the activation of the pituitary-adrenal axis by stress.
