摘要: 背景 高雄激素血症作为多囊卵巢综合征(PCOS)重要的临床特征之一,与代谢综合征密切相关。雄激素与2型糖尿病和胰岛素抵抗的相关研究尚不深入,研究结果不完全一致,尚未形成统一的科学结论。 目的 探讨不同糖耐量PCOS患者雄激素水平变化,及雄激素与糖代谢指标的关系。 方法 回顾性分析2018年3月至2020年12月在华中科技大学同济医学院附属协和医院就诊的954例PCOS患者雄激素、75 g口服糖耐量试验、胰岛素释放试验检测结果,计算体质指数(BMI)、游离雄激素指数(FAI)和稳态模型胰岛素抵抗指数(HOMA-IR)。依据葡萄糖耐量状态将患者分为正常葡萄糖耐量组(NGT组)、糖尿病前期组(IGT组)和2型糖尿病组(T2DM组)。依据FAI四分位数由低到高将PCOS患者分为Q1~Q4亚组,依据BMI将PCOS患者分为正常体质量(BMI<24.0 kg/m2)、超重(24.0 kg/m2≤BMI<28.0 kg/m2)和肥胖(BMI≥28.0 kg/m2)。比较不同葡萄糖耐量状态下的PCOS患者雄激素变化及雄激素对糖代谢指标的影响;分析雄激素对胰岛素抵抗的影响。 结果 NGT组490例,IGT组369例,T2DM组95例,三组患者BMI、游离睾酮(FT)、性激素结合球蛋白(SHBG)和游离雄激素指数(FAI)比较,差异均有统计学意义(P<0.01)。多元线性回归分析结果显示,总睾酮(T)是口服75 g葡萄糖后0.5 h血糖(Glu 30 min)(β=0.068,P=0.037)、胰岛素(β=0.098,P=0.002)、HOMA-IR(β=0.086,P=0.008)的影响因素,SHBG、FAI是口服75 g葡萄糖前后血糖(Glu 0 min、Glu 30 min、Glu 60 min、Glu 120 min、Glu 180 min)、糖化血红蛋白(HbA1c)(β=-0.187、0.277,P<0.001)、胰岛素(β=-0.226、0.371,P<0.001)、HOMA-IR(β=-0.224、0.377,P<0.001)的影响因素。与Q4亚组相比,Q1~Q3亚组的Ins 0 min、Ins 30 min、Ins 60 min、Ins 120 min、Ins 180 min、HOMA-IR较低(P<0.05)。正常体质量者的FT(β=0.119,P=0.031)和SHBG(β=-0.155,P=0.005)是HOMA-IR的影响因素,超重者SHBG(β=-0.199,P<0.001)和FAI(β=0.249,P<0.001)是HOMA-IR的影响因素,肥胖者的T(β=0.154,P=0.012)、雄烯二酮(A)(β=0.132,P=0.031)、FT(β=0.291,P<0.001)、SHBG(β=-0.176,P=0.004)、FAI(β=0.390,P<0.001)均会不同程度地影响HOMA-IR。 结论 PCOS患者糖代谢异常的影响因素包括T、SHBG、FAI,其中FAI对多项糖代谢指标的影响更为显著。FAI过高也会增加胰岛素分泌,对于不同体质量的PCOS患者,影响HOMA-IR水平的雄激素不尽相同。临床应根据这些因素为PCOS患者提供个性化降糖、降雄激素方案,减少相关并发症的发生。

Abstract:

Background

Hyperandrogenemia is one of the most important clinical features of polycystic ovary syndrome (PCOS) and is closely related to metabolic syndrome. The related researches evaluating the relationship between androgen and type 2 diabetes mellitus and insulin resistance were not enough, and their results were inconsistent, thus not forming an unified scientific conclusion.

Objective

To investigate the changes of androgen level in PCOS patients with different glucose tolerance, and the relationship between androgen and glucose metabolism.

Methods

This study selected 954 PCOS patients in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from March 2018 to December 2020, and collected data about androgen, 75 g glucose tolerance test and insulin release test. Body mass index (BMI), free androgen index (FAI) and homeostasis model insulin resistance index (HOMA-IR) were calculated. These patients were divided into normal glucose tolerance group (NGT), prediabetes group (IGT) and type 2 diabetes group (T2DM) according to the glucose tolerance status. PCOS patients were divided into Q1-Q4 subgroups based on the FAI quartile from low to high. PCOS patients were divided into normal (BMI<24.0 kg/m2), overweight (24.0 kg/m2≤BMI<28.0 kg/m2) and obesity subgroup (BMI≥28.0 kg/m2) according to BMI. This study compared the changes of androgen level, and the effects of androgen level on glucose metabolism in PCOS patients with different glucose tolerance, and analyzed the effect of androgen on insulin resistance.

Results

There were 490 patients in NGT group, 369 patients in IGT group and 95 patients in T2DM group. There were significant differences in BMI, FT, SHBG and FAI among these three groups (P< 0.01). Multiple linear regression analysis showed that T was a factor that affects Glu 30 min (β=0.068, P=0.037), Ins (β=0.098, P=0.002), HOMA-IR (β=0.086, P=0.008). SHBG and FAI were the factors that affect Glu 0 min, Glu 30 min, Glu 60 min, Glu 120 min, Glu 180 min, HbA1c (β=-0.187, 0.277, P< 0.001), INS (β=-0.226, 0.371, P<0.001), HOMA-IR (β=-0.224, 0.377, P<0.001). The levels of Ins 0 min, Ins 30 min, Ins 60 min, Ins 120 min, Ins 180 min and HOMA-IR of subgroup Q1-Q3 were significantly lower than that of subgroup Q4 (P< 0.05). FT (β=0.119, P=0.031) and SHBG (β=-0.155, P=0.005) were the factors that affect HOMA-IRin patients with normal weight. SHBG (β=-0.199, P<0.001) and FAI (β=0.249, P<0.001) were the factors that affect HOMA-IR in overweight patients. T, A, FT, SHBG and FAI are the factors that affect HOMA-IR (β=0.154, 0.132, 0.291, -0.176, 0.390, P<0.05) in obese patients.

Conclusions

T, SHBG and FAI had the impact on abnormal glucose metabolism in PCOS patients, and FAI had a more significant effect. High FAI increased insulin secretion. For PCOS women with different weight, the impact of androgens on HOMA-IR were different. Clinicians should provide the personalized glucose-lowering and androgen-lowering strategy to reduce the rates of related complications based on these factors.
