OBJECTIVE: Polycystic ovary syndrome (PCOS) is a female endocrinopathy characterized by hyperandrogenemia, insulin resistance, glucose intolerance, dyslipidemia, non-alcoholic fatty liver disease (NAFLD), and obesity. Hepassocin (HPS) is a hepatokine involved in energy and lipid metabolism. We aimed to investigate the role of HPS in metabolic dysfunction and its relationship with fatty liver in patients with PCOS.

PATIENTS AND METHODS: A total of 45 newly diagnosed PCOS patients and 42 healthy women of similar age were included in the study. Routine anthropometric, biochemical, and hormonal information were recorded. Serum HPS and high-sensitivity C-reactive protein (hsCRP) were measured, and NAFLD fibrosis score (NFS) and Fibrosis-4 (FIB-4) were calculated and correlated.

RESULTS: HPS and hsCRP values of the PCOS group were found to be significantly higher than controls (p=0.005, p<0.001, respectively). A positive correlation was found between both HPS and hsCRP and luteinizing hormone (LH) (p<0.001). No correlation was observed between HPS and NFS and FIB-4, however, only a weak negative correlation was observed between hsCRP and FIB-4. A negative correlation was found between HPS and BMI, waist circumference, fat ratio, and HbA1c (p<0.05). In multivariate regression analysis for HPS, R-squared is 0.898, and hsCRP, neck circumference, fat amount, and LH are significant factors.

CONCLUSIONS: NAFLD is an important dysmetabolic component of PCOS. Serum HPS is elevated in PCOS patients. We found a positive correlation between hsCRP and LH and a negative correlation between obesity indices, although we did not find an association between NFS and FIB-4, and HPS. In the future, large-scale molecular studies of HPS may be beneficial.
