ABSTRACT
INTRODUCTION:
Low-grade chronic inflammation may participate in PCOS etiology. Toll-like receptors (TLRs) may play a pivotal role in the initiation and progression of inflammatory process. We examined TLR2 and TLR4 gene polymorphisms in women with PCOS and their associations with metabolic/hormonal parameters. MATERIAL ANDMETHODS:
Sixty-eight women qualified for the study. PCOS was diagnosed in 40 women. The control group consisted of 28 women. All patients underwent anamnesis, physical examination, anthropometric measurements, and biochemical/hormonal assessments. The TLRs gene polymorphism was tested using PCR and the minisequencing method.RESULTS:
The frequency of TLR2 gene polymorphisms genotypes (rs3804099, rs3804100, and rs5743708) did not differ significantly between the groups. The difference in frequency of genotypes of TLR4 gene polymorphisms (rs4986790 and rs4986791) was close to the statistical significance level. No significant correlations between TLR2/TLR4 polymorphisms and anthropometric/metabolic parameters in PCOS group were observed. However, the relationship between HDL concentration and TLR2 S450S (rs3804100) polymorphism was close to the statistical significance level. Positive correlations between the two TLR4 polymorphisms (rs4986790 and rs4986791) were found, as well as between the TLR2 S450S (rs3804100) gene polymorphism and FSH concentration.CONCLUSIONS:
The TLR4 gene polymorphism may play a role in the PCOS etiopathogenesis but this observation needs further investigation.Palavras-chave
