ABSTRACT
PURPOSE:
Anti-Müllerian hormone (AMH) is proposed as a biomarker of polycystic ovary syndrome (PCOS). This study investigated (1) AMH concentrations in obese adolescents with PCOS versus without PCOS; (2) the relationship of AMH to sex steroid hormones, adiposity, and insulin resistance; and (3) the optimal AMH value and the multivariable prediction model to determine PCOS in obese adolescents.METHODS:
AMH levels were measured in 46 obese PCOS girls and 43 obese non-PCOS girls. Sex steroid hormones, clamp-measured insulin sensitivity and secretion, body composition, and abdominal adiposity were evaluated. Logistic regression and receiver-operating characteristic curve analyses were used, and multivariate prediction models were developed to test the utility of AMH for the diagnosis of PCOS.RESULTS:
AMH levels were higher in obese PCOS versus non-PCOS girls (8.3 ± .6 vs. 4.3 ± .4 ng/mL, p < .0001), of comparable age and puberty. AMH concentrations correlated positively with age in both groups, total and free testosterone in PCOS girls only, abdominal adipose tissue in non-PCOS girls, with no correlation to in vivo insulin sensitivity and secretion in either groups. A multivariate model including AMH (cutoff 6.26 ng/mL, area under the curve .788) together with sex hormone-binding globulin and total testosterone exhibited 93.4% predictive power for diagnosing PCOS.CONCLUSIONS:
AMH may be a useful biomarker for the diagnosis of PCOS in obese adolescent girls.Palavras-chave
