| Popis: | Objective – to identify different phenotypes of overweight in women with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) based on body mass index (BMI) and serum leptin levels, as well as to determine the frequencies of various metabolic disorders, hypertension and cardiovascular complications in individual phenotypes. Material and methods. The study included 50 women with RA and 46 with SLE aged 18 to 65 years without a history of diabetes and fasting hyperglycemia. The concentration of leptin (ELISA), insulin (electrochemiluminescence analysis) was determined in all patients, and the HOMA-IR index was calculated. Hyperleptinemia was diagnosed at leptin concentrations >11,1 ng/ml, insulin resistance (IR) – at HOMA-IR values ≥2,77. Three main phenotypes of overweight were distinguished: “classic” (BMI≥25 kg/m2 + hyperleptinemia), “healthy” (BMI≥25 kg/m2 , without hyperleptinemia), “hidden” or “latent” (BMI |
