The Role of Asymmetric and Symmetric Dimethylarginine in Acute Deep Vein Thrombosis

BackgroundIn this study, we aimed to determine the importance of asymmetric dimethylarginine (ADMA), symmetric dimethyl arginine (SDMA), and l-arginine levels which are influenced by the endothelial dysfunction in acute deep vein thrombosis (DVT), and compare their pretreatment and post-treatment levels.MethodsA total of 34 cases (19 men and 15 women, age range 42 ± 14 years) diagnosed with acute DVT and 34 control subjects (22 men and 12 women, age range 45 ± 11 years) without any vascular disorders were included in the study. The patients were administered low-molecular-weight heparin subcutaneously. Blood samples were obtained to measure ADMA, SDMA, and arginine levels before treatment and during the treatment (on 10th day). ADMA, SDMA, and l-arginine levels were measured using high performance liquid chromatography method.ResultsThe ADMA and SDMA levels were significantly higher in acute DVT patients when compared with the controls (P = 0.001). Post-treatment decrease of ADMA and SDMA levels when compared with the pretreatment levels were found as statistically significant (P = 0.001). Increase in l-arginine levels were not found significant when compared with the control group (P = 0.12) or post-treatment levels (P = 0.16).ConclusionsWe concluded that ADMA and SDMA levels can be used as parameters in clinical follow-up for determining the efficacy of treatment in acute DVT patients, and further studies are needed to further clarify the subject.
