OBJECTIVE: To evaluate serum concentrations of apelin in relation to the hormonal and metabolic profile in patients with and without polycystic ovary syndrome (PCOS).
STUDY DESIGN: A total of 45 women with PCOS and 45 age-matched controls were eligible for the study. Hirsutism scores, hormonal and metabolic profile as well as apelin levels were evaluated in each subject.
RESULTS: Women with PCOS exhibited lower serum concentrations of apelin than controls (194.1±50.7pg/ml versus 292.1±85.6pg/ml, p<0.001). Apelin levels were significantly correlated positively with body mass index (BMI), insulin, triglyceride (TG), free testosterone (fT) levels, modified Ferriman Gallwey scores and Homeostasis Model Assessment (HOMA) index; but negatively correlated with high density lipoprotein (HDL) levels in patients with PCOS (p<0.05). When overweight or obese (BMI≥25) and normal weight (BMI<25) women with PCOS were compared to BMI-matched controls, lower apelin levels were found in the PCOS group (226.7±45.4pg/ml versus 378.6±80.9pg/ml and 165.5±36.1 versus 249.0±46.6pg/ml, p<0.001, respectively).
CONCLUSION: The data suggest that serum apelin levels are lower in women with PCOS than in controls. Furthermore, apelin can be used as a specific marker for insulin sensitivity and lipid profile and this adipokine might play a role in the pathogenesis of PCOS.
