[FEATURES OF ROSACEA PATHOGENESIS IN PERIMENOPAUSAL WOMEN]

In patients with rosacea, the monitoring of blood melatonin in the menopausal period, as one of the criteria for assessing the severity of the disease, seems appropriate and pathogenetically justified. The aim of this study was determination of blood melatonin, VEGF, IL-8 concentration in perimenopausal period of women suffering by rosacea. 43 to 65 years old 15 women with various clinical manifestations of rosacea, and severe climacteric syndrome were under observation. The control group consisted of 15 female patients with rosacea but without climacteric syndrome. Melatonin, VEGF,IL-8 level in serum were determined by ELISA (IBL - international - reagent), the results were expressed in pg/ml).As the results of the study showed, the concentration of vasoactive peptides in patients with rosacea differes significantly from those in the control group. Increase the concentration of cytokinesin in the blood of patients with rosacea indicate that they are playing significant role in the pathogenesis of rosaceaAccording to the results of the study, the concentration of melatonin was reduced in all patients with rosacea (the main group). The degree of reduction was in direct correlation with the severity of climacteric syndrome (11,6÷1,5 pg/ml at a rate of ≥ 20,0 pg/ml). In the control group, the melatonin concentration was approaching to the norm (19.1 pg/ml). Statistical analysis of received data revealed the correlation in between of the severity of dermatosis and changes in lipid metabolism and concentration of melatonin (R = 0,91; p <0,05) in the main group of patients (with rosacea and climacteric period). Thus, on the basis of the obtained results it can be concluded that the inclusion of melatonin-containing preparations in prescription for rosacea patients having climacteric syndrome pathogenetically is justified.
