OBJECTIVE
To study the effects of oral contraceptive pills (OCP), the first-line treatment for PCOS, on high-density lipoprotein cholesterol (HDL-C) function (reverse cholesterol efflux capacity) and lipoprotein particles measured using nuclear magnetic resonance spectroscopy in obese women.
DESIGN
Secondary analysis of a randomized controlled trial (OWL-PCOS) of OCP or Lifestyle (intensive Lifestyle modification) or Combined (OCP + Lifestyle) treatment groups for 16 weeks.
PATIENTS
Eighty-seven overweight/obese women with PCOS at two academic centres.
MEASUREMENTS
Change in HDL-C efflux capacity and lipoprotein particles.
RESULTS
High-density lipoprotein cholesterol efflux capacity increased significantly at 16 weeks in the OCP group [0·11; 95% confidence interval (CI) 0·03, 0·18, P = 0·008] but not in the Lifestyle (P = 0·39) or Combined group (P = 0·18). After adjusting for HDL-C and TG levels, there was significant mean change in efflux in the Combined group (0·09; 95% CI 0·01, 0·15; P = 0·01). Change in HDL-C efflux correlated inversely with change in serum testosterone (r = -0·21; P = 0·05). In contrast, OCP use induced an atherogenic low-density lipoprotein cholesterol (LDL-C) profile with increase in small (P = 0·006) and large LDL-particles (P = 0·002). Change in small LDL-particles correlated with change in serum testosterone (r = -0·31, P = 0·009) and insulin sensitivity index (ISI; r = -0·31, P = 0·02). Both Lifestyle and Combined groups did not show significant changes in the atherogenic LDL particles.
CONCLUSIONS
Oral contraceptive pills use is associated with improved HDL-C function and a concomitant atherogenic LDL-C profile. Combination of a Lifestyle program with OCP use improved HDL-C function and mitigated adverse effects of OCP on lipoproteins. Our study provides evidence for use of OCP in overweight/obese women with PCOS when combined with Lifestyle changes.
目的
研究多囊卵巢综合征（PCOS）的一线治疗药物口服避孕药（OCP）对肥胖女性高密度脂蛋白胆固醇（HDL-C）功能（逆向胆固醇流出能力）以及使用核磁共振波谱法测量的脂蛋白颗粒的影响。
设计
对OCP组、生活方式干预组（强化生活方式改变）或联合治疗组（OCP + 生活方式干预）进行为期16周的随机对照试验（OWL-PCOS）的二次分析。
患者
两个学术中心的87名超重/肥胖PCOS女性。
测量指标
HDL-C流出能力和脂蛋白颗粒的变化。
结果
OCP组在16周时HDL-C流出能力显著增加[0·11；95%置信区间（CI）0·03，0·18，P = 0·008]，而生活方式干预组（P = 0·39）和联合治疗组（P = 0·18）未增加。在调整HDL-C和甘油三酯（TG）水平后，联合治疗组的流出能力有显著的平均变化（0·09；95%CI 0·01，0·15；P = 0·01）。HDL-C流出能力的变化与血清睾酮的变化呈负相关（r = -0·21；P = 0·05）。相比之下，使用OCP会导致致动脉粥样硬化的低密度脂蛋白胆固醇（LDL-C）谱，小LDL颗粒（P = 0·006）和大LDL颗粒（P = 0·002）增加。小LDL颗粒的变化与血清睾酮的变化（r = -0·31，P = 0·009）和胰岛素敏感指数（ISI；r = -0·31，P = 0·02）相关。生活方式干预组和联合治疗组的致动脉粥样硬化LDL颗粒均未显示出显著变化。
结论
使用口服避孕药与改善HDL-C功能以及伴随的致动脉粥样硬化LDL-C谱相关。生活方式干预方案与OCP联合使用可改善HDL-C功能，并减轻OCP对脂蛋白的不良影响。我们的研究为超重/肥胖PCOS女性在结合生活方式改变时使用OCP提供了证据。
