Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age women.
This study was conducted to investigate the effects of CoQ10 and/or vitamin E on cardiometabolic outcomes in patients with PCOS.
This randomized clinical trial was carried out among 86 women with PCOS. Patients were assigned to take CoQ10, vitamin E, CoQ10 plus vitamin E or placebo for 8 weeks. Fasting blood samples were obtained at the beginning and end of the study.
A significant decrease in serum triglycerides (TG) (p <0.001) was found following the administration of CoQ10 and/or vitamin E supplements compared with the placebo group. Supplementation with CoQ10 and vitamin E failed to affect total cholesterol levels. However, co-administration of CoQ10 and vitamin E resulted in a significant decrease in serum total cholesterol levels (9.92 [15.11, 4.74]). Additionally, only the combination of supplements was able to significantly reduce low-density lipoprotein-cholesterol (LDL-C) (‒9.63 [‒15.34, ‒3.92]), increase high-density lipoprotein-cholesterol (HDL-C) (2.33 [0.51, 4.16), reduce atherogenic coefficient (AC) (‒0.29 [‒0.43, ‒0.16], p = 0.03) and decrease visceral adiposity index (VAI) values. Co-Q10 and vitamin E (alone or in combination) had significant effects on non-HDL-C (p = 0.004), atherogenic Index of Plasma (AIP) (p = <0.001) and lipid accumulation product (LAP) (p <0.001) and SBP (p = 0.005). However, the reduction in DBP was statistically significant only for patients who received combined supplementations (p = 0.04).
In conclusion, CoQ10, vitamin E (alone or in combination) had beneficial effects on cardiometabolic outcomes among women with PCOS.
多囊卵巢综合征（PCOS）是育龄妇女中最常见的内分泌疾病。
本研究旨在探讨辅酶 Q10 和/或维生素 E 对 PCOS 患者心脏代谢结局的影响。
本随机临床试验纳入了 86 例 PCOS 患者。患者被分配服用辅酶 Q10、维生素 E、辅酶 Q10 加维生素 E 或安慰剂 8 周。在研究开始和结束时采集空腹血样。
与安慰剂组相比，辅酶 Q10 和/或维生素 E 补充剂治疗后血清甘油三酯（TG）显著下降（p<0.001）。辅酶 Q10 和维生素 E 补充剂未能影响总胆固醇水平。然而，辅酶 Q10 和维生素 E 联合使用可显著降低血清总胆固醇水平（9.92 [15.11，4.74]）。此外，只有补充剂联合使用才能显著降低低密度脂蛋白胆固醇（LDL-C）（-9.63 [-15.34，-3.92]），增加高密度脂蛋白胆固醇（HDL-C）（2.33 [0.51，4.16]），降低致动脉粥样硬化系数（AC）（-0.29 [-0.43，-0.16]，p=0.03）和降低内脏脂肪指数（VAI）值。辅酶 Q10 和维生素 E（单独或联合使用）对非高密度脂蛋白胆固醇（p=0.004）、血浆致动脉粥样硬化指数（AIP）（p<0.001）和脂质堆积产物（LAP）（p<0.001）和收缩压（SBP）（p=0.005）有显著影响。然而，只有接受联合补充的患者舒张压下降有统计学意义（p=0.04）。
总之，辅酶 Q10、维生素 E（单独或联合使用）对 PCOS 患者的心脏代谢结局有有益影响。
