Abstract
Polycystic ovary syndrome (PCOS) is the most common disease caused by complex
endocrine and metabolic abnormalities in women. Insulin resistance is considered
an important pathophysiological factor in the pathogenesis of PCOS. Here we
investigated the clinical values of C1q/TNF-related protein-3 (CTRP3) as
predictive factor for insulin resistance. Our study included 200 patients with
PCOS, among which 108 had insulin resistance. Serum CTRP3 levels were measured
using enzyme-linked immunosorbent assay. Predictive values of CTRP3 for insulin
resistance was analyzed using receiver operating characteristic (ROC) analysis.
Correlations of CTRP3 to insulin levels, obesity measurements and blood lipid
levels were determined using Spearman’s correlation analysis. Our data
suggested that PCOS patients with insulin resistance had a higher obesity, lower
high-density lipoprotein cholesterol, higher total cholesterol, higher insulin
levels and lower CTRP3 levels. CTRP3 had a high sensitivity (72.22%) and
specificity (72.83%). CTRP3 significantly correlated to insulin levels,
body mass index, waist-to-hip ratio, high-density lipoprotein, and total
cholesterol levels. The predictive value of CTRP3 in PCOS patients with insulin
resistance was supported by our data. Our findings suggest that CTRP3 is
involved in the pathogenesis and insulin resistance of PCOS, which indicates its
value as an indicator for the PCOS diagnosis.
