Introduction. Considering the very important role of adiponectin and leptin in\r\natherogenesis, it is important to study their relationship with other important factors in\r\nestablishing the cardiometabolic risk: hyperglycemia and serum lipids.\r\nPatients and Methods. There were studied 79 subjects (s), aged 59? 9 years, divided\r\ninto 3 groups according to body mass index (BMI): group I with BMI<25 kg/m2 - 19 s,\r\ngroup II with BMI 25-30 kg/m2 - 30s, and group III with BMI >30 kg/m2 - 30 s. In all\r\nsubjects the plasmatic levels of adiponectin, leptin and other cardiometabolic risk factors:\r\nblood glucose, total cholesterol, triglycerides, high density cholesterol, low density\r\ncholesterol were measured.\r\nResults. Considering the values of adiponectin and leptin in the three groups,\r\nadiponectin was significantly increased (14355?9120.40 vs 5889.167?6278.963 ng/mL,\r\np=0.015) and leptin significantly decreased (7212?7428.45 vs 9235.81?10988.66 pg/mL,\r\np=0.03), in group I in comparison with group II+III. Adiponectin and leptin were not\r\nsignificantly different in subjects with fasting glucose less or more than 110 mg/dL and the\r\nsame insignificant difference was registered for both adipokines between diabetic and non\r\ndiabetic subjects. Considering the plasma lipid fractions, it was registered an inverse\r\nsignificant correlation between adiponectin and total cholesterol, respectively LDL\r\ncholesterol, and a positive correlation with HDL cholesterol; leptin was inversely correlated\r\nwith HDL cholesterol, but not with LDL cholesterol or total cholesterol.\r\nConclusion. In the present study, the plasmatic values of adipokines (adiponectin and\r\nleptin) were correlated only to the BMI values (obesity) and respectively to the lipidic\r\nfractions. No correlation was registered with diabetes or impaired fasting glucose.
