| Background. Polycystic ovary syndrome (PCOS) is the most common endocrine disorder
in reproductive age women.
Objective. This study was conducted to investigate the effects of CoQ10 and/or vitamin
E on cardiometabolic outcomes in patients with PCOS.
Methods. 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.
Results. 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 lipoproteincholesterol
(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 5 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 5 0.004), atherogenic
Index of Plasma (AIP) ( p 5 !0.001) and lipid accumulation product (LAP) ( p ! 0.001)
and SBP ( p 5 0.005). However, the reduction in DBP was statistically significant only for
patients who received combined supplementations ( p 5 0.04).
Conclusions. In conclusion, CoQ10, vitamin E (alone or in combination) had beneficial
effects on cardiometabolic outcomes among women with PCOS. 2019 IMSS.
