In this randomized, double-blind, placebo-controlled study, 19 overweight women with polycystic ovary syndrome were randomized to a 3-month course of either metformin plus combined hormonal oral contraceptive (OC) (n = 9) or OC plus matched placebo (n = 10). After 3 months, both treatments had similar effects on androgen levels, lipid profile, insulin sensitivity, and serum inflammatory markers, but flow-mediated dilatation increased by 69.0% in the metformin plus OC group while it remained unchanged in the OC group. CLINICAL TRIAL REGISTRATION NO: NCT00682890.
在这项随机、双盲、安慰剂对照研究中,19 名患有多囊卵巢综合征的超重女性被随机分为三组,分别接受为期 3 个月的二甲双胍联合复方激素口服避孕药(OC)治疗(n = 9)、OC 联合匹配安慰剂治疗(n = 10)。3 个月后,两种治疗方法在雄激素水平、血脂谱、胰岛素敏感性和血清炎症标志物方面均有相似的效果,但二甲双胍联合 OC 组的血流介导扩张增加了 69.0%,而 OC 组则保持不变。临床试验注册号:NCT00682890。
