BACKGROUND/OBJECTIVES: OxLDL-β2GPI complex has been suggested to have a role in the development of atherosclerosis and other inflammatory diseases. The aim of this study was to investigate the possible association of circulating oxLDL-β2GPI with obesity-induced inflammatory state of adipose tissue and related comorbidities as metabolic syndrome development. SUBJECTS/METHODS: Two cohorts of subjects were examined in the study. Cohort I: 36 women with wide range of body mass index (17-48 kg m-2) and metabolic status (with or without metabolic syndrome (MS); cohort II: 20 obese women undergoing a dietary intervention (DI) consisting of 1-month very-low-calorie diet, and 5 months of weight-stabilization period. Serum levels of oxLDL-β2GPI were measured by enzyme-linked immunosorbent assay. Insulin sensitivity was evaluated by hyperinsulinemic-euglycemic clamp and homeostasis model assessment of insulin resistance. mRNA expression of macrophage markers was determined in both subcutaneous (SAT) and visceral (VAT) adipose tissue in cohort I and in SAT in cohort II. RESULTS: Serum oxLDL-β2GPI levels were increased in obese subjects with MS compared to lean or obese without MS (obese with MS: 26.6±5.0 vs lean: 15.17±1.97, P<0.001; vs obese without MS: 16.36±2.89, P<0.05). Serum oxLDL-β2GPI correlated with MS indices (glucose, high-density lipoprotein, triglyceride and ureic acid) and with mRNA expression of macrophage markers in VAT. Weight-reducing DI decreased serum oxLDL-β2GPI levels together with lipid parameters and the mRNA expression of inflammatory markers in SAT. CONCLUSIONS: OxLDL-β2GPI seems to be an important marker of visceral adipose tissue inflammation and possibly a factor contributing to insulin resistance and metabolic syndrome development in obese patients.
