The Relationship between Polycystic Ovary Syndrome and Serum Periostin Level

OBJECTIVE: To determine the changes of circulating periostin levels in polycystic ovary syndrome (PCOS) and its relationship with metabolic disorders. STUDY DESIGN: Cross-sectional study. PLACE AND DURATION OF STUDY: Konya Research and Training Hospital, Turkey between September 2018 and April 2020. METHODOLOGY: Patients with PCOS were compared with healthy individuals as control. The demographics, laboratory findings, anthropometric measurements, the levels of serum periostin and carotid intima media thickness (CIMT) were evaluated and compared. RESULTS: There was no significant difference between patients with PCOS (n = 53) and controls (n = 35), according to demographic and laboratory findings and anthropometric measurements. The CIMT in patients with PCOS and control groups were measured as 0.5 ± 0.06 mm and 0.43 ± 0.1 mm, respectively (p <0.003). The levels of periostin in the patients with PCOS and control groups were found to be 6.43 ± 6.19 ng/mL and 3.61 ± 3.79 ng/mL, respectively (p <0.018). No statistically significant correlations were found according to periostin levels and metabolic variables. CONCLUSION: Although there was no significant correlation between the periostin levels and the metabolic variables in patients with PCOS as compared to those without the periostin levels, but CIMT were higher in PCOS group.
