摘要:
目的:通过对克罗米芬(clomiphene citrate,CC)抵抗的多囊卵巢综合征(plycystic ovary syndrome,PCOS)患者相关危险因素的logistic回归分析,探讨临床上难治性PCOS诊疗的思路和策略。方法:92例PCOS患者分为CC有效组和CC抵抗组,均测其体质量、身高、年龄、葡萄糖耐量实验(glucose tolerance test,OGTT)(0’、120’)、胰岛素(insulin)(0’、120’)、卵泡刺激素(fol-licule-stimulating hormone,FSH)、黄体生成素(luteinizing hormone,LH)、睾酮(testosterone,T)、雌二醇(estradiol,E2)以及同型半胱氨酸(homocysteine,Hcy),并计算体质指数(body mass index,BMI)和稳态模式评估法测定胰岛素抵抗指数(homeostasis model assessment for insulin resistance,HOMA-IR)。将差异有统计学意义的指标进行logistic回归分析以及ROC曲线分析。结果:CC抵抗组与CC有效组之间比较,年龄(P=0.000)、BMI(P=0.005)、Hcy(P=0.000)、OGTT(0’)(P=0.000)、INS(0’)(P=0.014)、T(P=0.042)、HOMA-IR(P=0.000)差异有统计学意义;Hcy、OGTT(0’)、INS(0’)、T、HOMA-index、BMI、年龄指标与CC抵抗呈负相关;Hcy的ROC曲线下面积为0.981,95%CI=0.972~0.990。结论:Hcy在预测难治性CC抵抗的PCOS中是1项最佳的危险预测指标。
Abstract:
Objective:To discuss the strategies for treating refractory plycystic ovary syndrome(PCOS) by risk factors logistic regression analysis in clomiphene citrate(CC) resistant PCOS patients. Methods:A total of 92 PCOS patients were divided into CC resistant group and CC effective group. Patients' weight,height,age,glucose tolerance test(OGTT)(0’,120’),insulin(0’,120’),follicle-stimulating hormone(FSH),luteinizing hormone(LH),testosterone(T),estradiol(E2) and homocysteine(Hcy) were measured;the body mass in-dex(BMI) and homeostasis model assessment for insulin resistance(HOMA-IR) were calculated. The statistically significant differ-ence was analyzed by logistic regression analysis and ROC curve analysis. Results:There were statistically significant differences in age(P=0.000),BMI(P=0.005),Hcy(P=0.000),OGTT(0’)(P=0.000),INS(0’)(P=0.014),T(P=0.042),HOMA-index(P=0.000) be-tween CC resistant group and CC effective group. Hcy,OGTT(0’),INS(0’),T,HOMA-index,BMI,and age were negatively correlat-ed with CC resistance.The area under ROC curve was 0.981 Hcy,95%CI=0.972-0.990. Conclusion:Hcy is the best risk predictors in predicting CC resistant of refractory PCOS.
