Design: Prospec tive, case-control. Setting: University medical center. Patient(s): Two hundred seventy-one PCOS patients and 260 eumenorrheic, non-hirsute, control women. I ntervention(s): History and physical examination and blood sampling. Main Outcom e Measure(s): Total T, free T, DHEAS, sex hormone-binding globulin, and fasting glucose and insulin levels; homeostatic model assessment values for IR (HOMA-I R) and percent β-cell function (HOMA-%β-cell). Result(s): Patients with PC OS and controls differed significantly in all parameters studied, except fasting glucose. Because the HOMA-IR and HOMA-%β-cell values were variably associa ted with race, age, and body mass index, the HOMA-IR and HOMA-%β-cell value s were then adjusted for these cofounders. After adjustment, 64.4%of PCOS patie nts were noted to be insulin resistant, and 2.6%had β-cell dysfunction. Compa red with PCOS patients without IR (n = 96), patients with IR (n = 174) were more obese and had higher β-cell function. Conclusion(s): In patients with PCOS, t he prevalence of IR was 64%according to the HOMA-IR measurement, after adjustm ent. Patients with IR were more clinically affected. Although IR is a common abn ormality in PCOS, it does not seem to be a universal feature.展开更多

文摘目的:以多囊卵巢综合征(polycystic ovary syndrome,PCOS)人群为研究对象,通过构建包含补体C3的胰岛素敏感性(insulin sensitivity,IS)评分模型,探索一种简便易行的方法对PCOS患者的IR进行评估。方法:纳入99名PCOS患者及116名年龄匹配的正常女性,测量人体参数及空腹血生化指标(胰岛素、hs-CRP、补体C3等),计算稳态模型胰岛素抵抗指数(homeostasis model assessment of insulin resistance,HOMA2-IR)。对所有PCOS患者及其中20名正常对照行高胰岛素-正葡萄糖钳夹术,结果以M值表示。在PCOS组中,采用多元线性回归,以M值为应变量,以BMI、LDL-C、补体C3、超敏C反应蛋白、空腹血清胰岛素为自变量,建立IS评分(即M值的预测值)模型方程,用ROC曲线评估该模型诊断IR的价值。结果:IS评分=19.36-0.35×BMI-2.28×C3(R^2=0.54,P=0.000)。IS评分和HOMA2-IR诊断PCOS患者IR的ROC曲线下面积分别为0.89(95%CI=0.82~0.96)和0.75(95%CI=0.64~0.86),当IS评分=8.93时,其诊断PCOS患者IR的灵敏度和特异度分别为0.70和0.95,Youden指数0.63。当HOMA2-IR=0.47时,其诊断的灵敏度和特异度分别为0.60和0.88,Youden指数0.47。结论:包含补体C3的IS评分模型评估PCOS人群的IR具有较好的诊断价值。
