Abstract
Objective
To investigate the effect of orlistat combined with drospirenone/ethinylestradiol tablets (DRSP/EE) on the visceral fat area (VFA) compared to DRSP/EE-alone in overweight or obese patients with polycystic ovary syndrome (PCOS).
Methods
90 PCOS patients [body mass index (BMI) ≥24kg/m2] were recruited for a prospective, open-label, 1:2 paired 3-monthly study. All were included during the per-protocol defined recruitment time and numbered according to the entry-order: group-1: No.1-60, orlistat plus DRSP/EE; group-2: No.61-90, DRSP/EE-alone. Both groups received the same comprehensive intervention in terms of individualized, standardized management and lifestyle monitoring such as diet and exercise. Primary study-endpoint was VFA, secondary endpoints were anthropometric indices, sex hormones and glucolipid metabolism. Within- and between-group analyses were performed.
Results
VFA [cm2] in group-1 after treatment decreased significantly (p = 0.001), and the between-group comparison was highly significant (p = 0.001). Body weight, hip circumference (HC), BMI, body fat (BF), free testosterone (FT) and low-density lipoprotein-cholesterol (LDL-C) significantly decreased in both groups (within-group analysis); the decrease in group-1 was significantly greater than in group-2 (p < 0.05). Systolic and diastolic blood pressure (SBP/DBP) and fasting plasma glucose (FPG) in group-1 were significantly decreased, significantly more in group-1 than in group-2 (p < 0.05).
Conclusion
This study is the first to investigate the effect of orlistat combined with DRSP/EE in overweight or obese PCOS patients compared with using DRSP/EE-alone. Orlistat combined with DRSP/EE was better than using DRSP/EE-alone in reducing VFA, body weight, FT, BP and FPG, which provides evidence for the choice of rational drug use in clinical practice.
摘要
目的
研究联合应用奥利司他和屈螺酮/炔雌醇片 (DRSP/EE) 与单用 DRSP/EE 相比对超重或肥胖多囊卵巢综合征 (PCOS) 患者内脏脂肪面积 (VFA) 的影响。
方法
90名PCOS患者[体重指数(BMI)≥24kg/m2]被招募参加一项前瞻性、非盲、1:2配对的3个月的研究。所有患者都在协议规定的招募时间内被招募, 并按照入组顺序进行编号:第一组:编号1-60, 联合应用奥利司他和DRSP/EE;第二组:编号61-90, 单独应用DRSP/EE。两组都接受相同的综合干预, 即个性化、标准化管理和生活方式监测如饮食和运动。主要研究终点是VFA, 次要研究终点是人体测量指数、性激素和糖脂代谢。进行组内和组间分析。
结果
治疗后第1组的VFA[cm2]明显下降(P=0.001), 组间比较有明显意义(P=0.001)。两组的体重、臀围(HC)、BMI、体脂(BF)、游离睾酮(FT)和低密度脂蛋白胆固醇(LDL-C)都明显下降(组内分析);第1组的下降幅度明显大于第2组(p < 0.05)。第1组的收缩压和舒张压(SBP/DBP)以及空腹血糖(FPG)都明显下降, 且下降幅度明显大于第2组(P < 0.05)。
结论
本研究首次研究了奥利司他联合DRSP/EE与单独使用DRSP/EE相比对超重或肥胖的PCOS患者的影响。奥利司他联合DRSP/EE在降低VFA、体重、FT、BP和FPG方面优于单独使用DRSP/EE, 这为临床实践中合理用药的选择提供证据。
