Abstract:
Objective To investigate the diagnostic value of serum anti-Müllerian hormone combined with sex hormones for polycystic ovary syndrome ( PCOS).Methods The serum levels of anti-Müllerian hormone ( AMH), testosterone ( T), luteinizing hormone ( LH), follicle-stimulating hormone (FSH) and the estradiol ( E2) were measured by electrochemiluminescence method in 82 patients with PCOS and 60 controls. The sensitivities, specificities and the areas under the receiver operating characteristic curves ( ROC-AUC) of the indicators and their combination for diagnosis of PCOS were compared by chi-square test and Z test separately.The correlations of serum AMH levels with age and sex hormones levels were analyzed separately by Spearman correlation analysis .Results The levels of serum AMH, T, LH and LH/FSH ratio in patients with PCOS were obviously higher than those in controls (62.19 pmol/L vs 27.63 pmol/L, 1.39 nmol/L vs 0.88 nmol/L, 12.72 IU/L vs 6.44 IU/L, 2.17 vs 1.17, U＝592.00, 1 096.00, 1 233.50, 1 134.00, all P＜0.01).The sensitivity of AMH (80.5%, 66/82) for diagnosis of PCOS was higher than that of LH (62.2%, 51/82) and LH/FSH ratio (54.9%, 45/82, χ2＝5.6, 13.79, all P＜0.05), but no significant difference was found when comparing with T (72%, 59/82, χ2＝1.71, P＞0.05 ) .The sensitivity of AMH ( 80.5%, 66/82 ) increased when combined with T (89.0%, 73/82), LH (87.8%, 72/82) and T+LH (95.10%, 78/82, χ2＝5.14, 4.17, 10.08, all P＜0.05), but no significant change by the combination of AMH +LH/FSH (85.4%, 70/82, χ2＝2.25, P＞0.05) .The specificity of AMH (80%, 48/60) for diagnosis of PCOS was no significant difference compared with that of T (71.7%, 43/60), LH (85%, 51/60), and LH/FSH ratio (91.7%, 55/60) (χ2＝3.20, 0.36, 2.77, all P＞0.05) .Also no increase when combined with T (71.7%, 43/60), LH (73.3%, 44/60), LH/FSH (75%, 45/60) and T +LH (66.7%, 40/60, χ2＝3.20, 2.25, 1.33, 3.38, all P＞0.05).The ROC-AUC of multiple indicators for diagnosis of PCOS were compared , AMH (0.880) was higher than T, LH and LH/FSH ratio (0.778, 0.760, 0.778, Z＝2.12, 2.46, 2.12, all P＜0.05), but no significant differences were found comparing with AMH and the combination of AMH +T, AMH+LH, AMH+LH/FSH and AMH+T+LH (0.892, 0.897, 0.898, 0.902, Z＝0.31, 0.45, 0.48, 0.59, all P＞0.05).Serum AMH levels were positively correlated with T , LH levels and LH/FSH ratio (r＝0.258, 0.241, 0.290, all P＜0.05), but not correlated with age in PCOS group (r＝-0.178, P＞0.05).In the control group, AMH levels had no correlations with T, LH levels and LH/FSH ratio (r＝0.025, 0.104, 0.111, P＞0.05), while negatively correlated with age (r＝-0.307, P＜0.05).The cutoff value of AMH for diagnosis of PCOS decreased with age .Conclusions The sensitivity of AMH for diagnosis of PCOS was higher than that of LH and LH /FSH ratio, and the sensitivity could be further improved by the combination with T or /and LH without reducing the specificity .Age-stratified cut-off values of AMH were better for accurate diagnosis of PCOS.
