Relationship of plasma acylation stimulating protein with blood lipid profile in women with pulycystic ovary syndrome / 中华内分泌代谢杂志

ABSTRACT

Objective To study the relationship of plasma aeylation stimulating protein (ASP) with complement C3, C-reactive protein (CRP) and blood lipid levels in women with polyeystic ovary syndrome (PCOS). Methods Thirty-four patients with PCOS were divided into two groups obese PCOS group [body mass index (BMI)≥25 kg/m2] and non-obese PCOS group (BMI<25 kg/m2). 41 age-matched non-PCOS women were also divided into two groups simply obese group (BMI≥25 kg/m2) and non-obese control group (BMI <25kg/m2). Plasma ASP in the 4 groups was detected by enzyme linked immunosorbent assay (ELISA) method.Complement C3 and CRP were determined by immunoturbidimetrie assay. Plasma free fatty acid (FFA)concentration was determined by colorimetric enzymatic assay, plasma triglycerides (TG) by GPO-PAP method and total cholesterol (TC) by COD-PAP method. Results The plasma ASP were significantly increased in the obese PCOS group, the non-obese PCOS group and the obese group as compared with the control group [(36.4±10.9,34.8±9.9, 35.1±14.0, 24.8±7.8) nmol/L, respectively, all P<0.05]. The concentrations of complement C3 were significantly higher in the obese PCOS group and the obese group than that in the control group [(2.2±1.2,2.5±1.5, 1.1±0.7) g/L, respectively, bothP <0.05]. The concentrations of CRP were significantly increased in the obese PCOS group, non-obese PCOS group and obese group as compared with the control group [(32.1±29.2, 30.0±24.8, 23.8±5.5, 7.5±4.8)mg/L, respectively, all P<0.05]. Univariate analysis showed that both plasma ASP and C3 were positively correlated with BMI, CRP, FFA and TG. CRP was positively correlated with BMI, FFA, TG and TC. Conclusion Plasma ASP, C3 and CRP levels in women with PCOS axe increased. They are strongly associated with disturbed lipid metabolism. The lack of association between ASP and complement C3 suggests that the conversion of C3 to ASP may be affected by other factors.
