摘要: Down syndrome (DS) patients have an increased risk of developing pulmonary hypertension (PH). Increased plasma levels asymmetric dimethylarginine (ADMA) may contribute to vascular dysfunction in adults with idiopathic hypertension. Our goal was test the hypothesis that DS PH higher ADMA than without PH. definitive (n = 6) and no evidence 12) were studied. Plasma arginine, ADMA, nitrite/nitrate (NOx; stable metabolites nitric oxide (NO)) measured. arginine concentration lower (p < 0.05) (23 ± 11 μM) versus non-PH (46 24 μM). 0.005) (18.0 4.2 (8.6 5.9 NOx (4.5 1.7 (8.5 7.3 These results are consistent contributing NO production suggest be a potential biomarker for patients.
