title: Plasma apelin levels in patients with polycystic ovary syndrome.
abstract: OBJECTIVE
  The aim of the study was to evaluate plasma apelin levels in patients with polycystic ovary syndrome (PCOS) and healthy controls.
  
  
  METHODS
  Plasma apelin levels, serum lipid levels, serum hormone levels, and homeostasis model assessment-insulin resistance (HOMA-IR) values of 32 patients with PCOS and 31 healthy women forming the control group were checked.
  
  
  RESULTS
  Plasma apelin levels of the PCOS group (0.350±0.083 ng/ml) were significantly higher than those of the control group (0.246±0.045 ng/ml) (p<0.001). No significant correlation was detected between apelin levels and biochemical or clinical data in PCOS group.
  
  
  CONCLUSIONS
  Plasma apelin levels were significantly higher in PCOS patients.
