目的探讨血清C反应蛋白(CRP)/高分子量脂联素(HMWA)比值与代谢综合征(MS)的相关性,分析CRP/HMWA比值作为一种新的生物学标志物在预测MS过程中与单独使用CRP、HMWA相比是否具有优势。方法共纳入研究对象170例,根据2009年国际多学会联合声明(JIS)的MS诊断标准分为MS组(n=94)和非代谢综合征(non-MS)组(n=76);所有研究对象均行口服葡萄糖耐量试验(OGTF)及胰岛素释放试验。采用ELISA法测定血清HMWA浓度,采用化学发光法测定血清CRP浓度。结果MS组血清CRP/HMWArE值水平高于non-MS组(P〈0.01)。简单相关分析显示,血清CRP/HMWA水平与体质指数(BMI)、腰围(WC)、腰臀比(WHR)、收缩压(SBP)、空腹血糖(FPG)、OGTr2h血糖(2hPG)、空腹胰岛素(Fins)、OGTr2h胰岛素(2hIns)、糖化血红蛋白(HbAlc)、三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、稳态模型胰岛素抵抗指数(HOMA-IR)、CRP呈正相关(P〈0.05或P〈0.01),与高密度脂蛋白胆固醇(HDL-C)、胰岛13细胞功能(HOMA-β)、HMwA呈负相关(P〈0.01)。Logistic回归显示,血清CRP/HMWA升高是Ms的危险因素(P〈0.05)。高CRP低HMWA组MS检出率高于低CRP高HMWA组(P〈0.01)。血清CRP/HMWA预测MS的ROC曲线下面积高于CRP及HMwA(P〈0.05)。结论与血清CRP、14MWA相比,用血清CRP/HMWA预测MS更有价值。
Objective To investigate the relationship of ratio of serum C-reactive protein(CRP) to high-molecular-weight adiponectin (CRP/HMWA ratio) levels with metabolic syndrome (MS) and evaluate whether CRP/HMWA ratio is more useful than CRP or HMWA value alone for prediction of MS. Methods A total of 170 Chinese subjects were divided into MS group( n = 94) and non-MS group (n = 76) respectively based on the criteria of 2009 Joint Interim Statement. Oral glucose tolerance test (OGTF) and insulin relea- sing test were performed for all subjects. Fasting serum HMWA level was determined by ELISA. Serum CRP concentrations were meas- ured by chemiluminescence method. Results Serum CRP/HMWA ratio of MS patients was significantly higher than that of non-MS subjects( P 〈 0.01 ). Serum CRP/HMWA ratio positively correlated with body mass index(BMI) , waist circumference(WC) , waist to hip ratio( WHR), systolic blood pressure( SBP), fasting blood glucose( FPG), OGTY 2-hour postload glucose(2hPG), fasting insulin ( Fins ), OGTF 2-hour insulin ( 2 bins ), glycosylated hemoglobin A1 C ( HbA 1 c ), triacylglycerol ( TG), total cholesterol( TC ), low den- sity lipoprotein cholesterol(LDL-C) , homeostasis model insulin resistance index(HOMA-IR) and CRP( P 〈 0.05 or P 〈 0.01 ) , but negatively correlated with high density lipoprotein cholesterol( HDL-C), HOMA-[3 and HMWA( P 〈 0.01 ). Logistic regression analysis revealed that increased CRP/HMWA ratio was associated with elevated odds of MS( P 〈 0.05 ). The diagnosis rate of MS in the high CRP-low HMWA group was higher than that in low CRP-high HMWA group ( P 〈 0.01 ). The AUC of CRP/HMWA ratio in receiver operating characteristic curve(ROC) analysis for MS was significantly greater than that of CRP or HMWA alone( P 〈0.05 ). Conclu- sion Serum CRP/HMWA ratio might be superior marker for predicting MS compared with CRP or HMWA alone.
