Investigation of dermatology life quality index and serum prolactin and serum dehydroepiandrosterone sulphate levels in patients with chronic urticaria.

PMID 25543039


Chronic urticaria (CU) is known to be one of the most disturbing diseases which significantly affect the quality of life. Prolactin (PRL) and DHEA-S (dehydroepiandrosterone sulfate) are stress-associated hormones in chronic urticaria. In the present study, we measured DHEA-S and prolactin levels of CU patients, compared them with healthy subjects and evaluated the association between disease status and serum levels. Plasma DHEA-S and serum PRL concentrations were measured in 48 CU patients and 31 healthy subjects. CU activity was assessed with the use of the symptom scores recommended with EAACI/GALEN/EDF guidelines. All the patients participating in this study were evaluated by means of Dermatology Life Quality Index (DLQI). With respect to DLQI and clinical activity scores, plasma DHEA-S and serum prolactin levels were compared. Median plasma concentration of DHEA-S was significantly lower in CU patients as compared with healthy subjects (p = 0.026). DHEA-S levels of females were significantly lower than males (p = 0.001). Mean PRL values of the patients were higher than the controls, but not statistically significant (p = 0.619) and there was a statistically signifcant inverse correlation with DHEA-S levels (p = 0.04, r = -0.298). Therewas a significant correlation between DLQI and clinical disease activity (p < 0.001, r = 0.748). The exact relation of hormones to CU pathogenesis remains to be determined by further clinical studies. In addition, therapies aiming to increase DHEA-S and decrease PRL may be subject to trial in CU.
