Objective: Scarce clinical and experimental studies suggest that hepcidin can be a protein participating in the development of metabolic disorders, while its synthesis and concentration in the circulation outside of the iron metabolism parameters can be influenced by hormones. The aim of the present study was to determine the correlation between the concentration of hepcidin in serum and the occurrence of insulin resistance and hyperandrogenemia in women with PCOS.
Patients and methods: Five groups of women with PCOS were divided based on: correct body mass (17 without hyperandrogenemia and insulin resistance - G1; 17 with hyperandrogenemia and without insulin resistance - G2; 11 without hyperandrogenemia and with insulin resistance - G3; 10 with hyperandrogenemia and insulin resistance - G4), metabolic and hormonal parameters and selected markers of iron metabolism.
Results: Serum glucose levels were significantly higher in the group G3 than G1 and in the group G4 than G1 and G2. Serum insulin levels and HOMA-IR values were significantly higher in the groups G3 and G4 than G1 and G2. Serum androstenedione levels were significantly higher in the group G2 than G1 and G3 than G2. Serum transferrin levels were significantly lower in the group G1 than in the reaming study groups.
Conclusions: It has been demonstrated that insulin resistance and hyperandrogenemia appear to be the factors decreasing the concentration of transferrin circulation, but not the remaining parameters of the iron metabolism in the studied women. No relationship between the concentration of hepcidin circulation and other studied parameters of the iron metabolism and the parameters of the carbohydrate metabolism was discovered. Androstenedione can stimulate hepcidin synthesis in women with PCOS with correct body mass.
