The relationship between glomerular filtration rate, and metabolic and inflammatory parameters in obese and non-obese patients with polycystic ovary syndrome

Abstract

AimTo investigate the relationship between glomerular filtration rates (GFR), and homeostasis model assesment of insulin resistance (HOMA-IR), C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) in patients with polycystic ovary syndrome (PCOS). Material and methodsThirty-one overweight and obese PCOS patients with body mass index (BMI)≥25kg/m2 and 25 non-obese PCOS patients with BMI<25kg/m2 were included into patients’ group, while 23 overweight and obese, and 25 non-obese age-and BMI-matched healthy individuals (aged between 18 and 40 years), were enrolled as controls. Levels of serum creatinine, glucose, insulin, CRP, and complete blood count were measured. eGFR, HOMA-IR and NLR were also calculated. ResultsIn PCOS group, HOMA-IR (p=0.001), CRP (p=0.025) and waist hip ratio (WHR) (p=0.011) were higher than controls. In obese PCOS sub-group, HOMA-IR (p=0.004) and WHR (p=0.002) were higher than obese controls. In non-obese PCOS sub-group, HOMA-IR (p=0.001) were higher than non-obese controls. In obese PCOS sub-group; HOMA-IR (p=0.001) and CRP (p=0.001) levels were significantly higher than non-obese PCOS sub-group. In terms of other parameters, no significant difference was found between the groups. The analysis showed a negative correlation between GFR, and BMI and HOMA-IR in PCOS group, between GFR, WHR and insulin levels in obese PCOS sub-group, and between BMI, and HOMA-IR and NLR in non-obese PCOS sub-group. ConclusionAlthough HOMA-IR and CRP were higher in PCOS group, there was no difference in NLR and GFR levels between those with PCOS and controls.
