摘　　要：Objective: To determine serum pannexin-1 channel levels and their association with hair loss in women with PCOS diagnosed with female androgenetic alopecia (FAGA). Materials and Methods: Thirty-five women with PCOS who presented with diffuse and treatment-resistant progressive hair loss and were diagnosed with FAGA were included in the study. 25 patients who were diagnosed with female androgenetic alopecia but did not have PCOS were considered as the control group. PCOS and control groups were matched by age. Follicular miniaturization, displacement of terminal hairs with vellus hairs, and a diffuse decrease in hair density were accepted as FAGA in the trcihoscopy examination of the vertex and bitempoaral area. On the third day of the menstrual cycle serum FSH, LH, testosterone, PRL and insulin levels were measured. Insulin resistance was calculated with HOMA-IR. Serum pannexin-1 channel levels of each group were mesured with ELISA. Results: Serum pannexin 1 channels levels of FAGA group due to PCOS were found to be significantly higher than FAGA patients in the control group (2.72 ± 1.09 ng/mL vs 1.65 ± 0.97 ng/mL, p < 0.01). Serum LH, insulin and testosterone levels of PCOS group were significantly higher than controls. HOMA-IR values were significantly higher and >2.5 in the PCOS group compared to the controls. PRL values were similar except for one patient with elevated PRL. Serum FSH values were the same in both groups. A positive and significant correlation was found between pannexin 1 channels levels and HOMA-IR and serum testosterone levels (r = 0.650, p Conclusions: In addition to hyperandrogenemia, increased pannexin 1 channel levels may play a role in the etiology of PCOS associated FAGA, as it impairs the communication between the skin and hair follicle.Objective: To determine serum pannexin-1 channel levels and their association with hair loss in women with PCOS diagnosed with female androgenetic alopecia (FAGA).
