Abstract: Objective  To access the effect of Orlistat combined with drospirenone/ethinylestradiol tablets (DRSP/EE) on the lipoprotein(a), glycolipid metabolism and hepatorenal function compared to DRSP/EE-alone in overweight or obese patients with polycystic ovary syndrome (PCOS). Methods  We conducted a randomized controlled trial involving 69 overweight or obese PCOS patients. In  principle of comparable baseline characteristics between groups, all participants were randomly assigned into two groups in a 1∶2 ratio, who received DRSP/EE alone as the control group(n=23) and DRSP/EE plus Orlistat as the observation group(n=46) for 12 weeks. Both groups got the same comprehensive intervention regarding diet and physical activities, which is standardized in Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Changes in cardiovascular risk factors including lipoprotein(a)[Lp(a)], weight, waist circumference (WC), total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), fasting plasma glucose (FPG), fasting insulin (FINS), homocysteine (HCY), and uric acid (UA) were observed before and after different regiments. Results  After 12 weeks of treatment, the Lp(a), LDL-C, FPG, and body weight levels of the observation group decreased significantly compared with the control group (P<0.05). The levels of WC, TC, FINS, UA, and HCY in the observation group decreased, and the FINS level increased in the control group, but there was no significant statistical significance (P>0.05). HDL-C and TG in the two groups were higher than those before treatment, and the difference was not statistically significant (P>0.05). Conclusions  Olistat combined with DRSP/EE can reduce the levels of Lp(a), LDL-C, FPG, and body weight in overweight or obese PCOS patients, which provides evidence for the choice of rational drug use in clinical practice.
