Abstract

Background: This research investigated the symbiotic supplement influences on serum glycemic indices and lipids
as well as apelin rates and obesity values in polycystic ovary syndrome (PCOS) patients.

Materials and Methods: A total of 68 obese or overweight patients (20-44 years old) with PCOS were enrolled to
conduct a randomized double-blinded placebo-controlled clinical trial. A total of 34 people in the synbiotic group received
a synbiotic supplement and 34 people in the placebo group received placebo, daily for 8 weeks. Fasting blood
specimens, anthropometric measurements and dietary intake data were gathered three times during the study. The
information was analyzed by independent t test, paired t test, analysis of covariance and chi-square test.

Results: Synbiotic supplementation significantly decreased serum fasting glucose (P=0.02), insulin (P=0.001), homeostatic
model assessment for insulin resistance (IR, P=0.001), weight (P=0.02), body mass index (BMI, P=0.02),
waist circumference (WC, P=0.01), hip circumference (HC, P=0.02), and waist-to-height ratio (WHtR, P=0.02) but
significantly increased high-density lipoprotein (HDL) cholesterol (P=0.02) compared to the placebo. At the end of the
trial, no significant differences were seen in serum total cholesterol, triglyceride (TG), low-density lipoprotein (LDL)
cholesterol, or apelin levels as well as waist-to-hip ratio (WHR) between the two groups.


Conclusion: Synbiotic supplementation improved glycemic indices, lipid profile and obesity values in women
with PCOS. These beneficial effects were not related with alterations in serum apelin levels (Registration number:
IRCT20100408003664N19).
