ABSTRACT
This study was performed to test whether plasma asymmetric dimethylarginine (ADMA) concentrations are related to obesity and obesity complications including decrement in insulin sensitivity and adiponectin levels, dyslipidemia and low-grade inflammation. Asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) concentrations were analyzed by HPLC in 17 overweight (BMI ≥ 25 kg/m2) and 40 obese (BMI ≥ 30 kg/m2) premenopausal women. Age-matched healthy women were studied as controls. Obesity did not give rise to a significant change in circulating ADMA levels but reduced in SDMA levels. As compared with control subjects (0.441 ± 0.102 µM), ADMA values in overweight and obese subjects were found to be as 0.412 ± 0.102 and 0.436 ± 0.093, respectively. No Pearson’s association of ADMA with relevant risk variables for cardiovascular disease, including blood pressure, insulin sensitivity, inflammatory markers, lipid and adiponectin levels. However, in linear regression analysis, BMI, diastolic blood pressure, glucose, insulin, and IL-8 emerged as significant predictors of ADMA. In spite of obese women have elevated hs-CRP, triglyceride levels and decreased insulin sensitivity, adiponectin and HDL-cholesterol levels, all of which is closely linked risk factors for cardiovascular disease, circulating ADMA levels remained unchanged in obese individuals as compared with controls.
