Plasma levels of dimethylarginines in preterm very low birth weight neonates: its relation with perinatal factors and short-term outcome.

ABSTRACT: Endogenously produced inhibitors of nitric oxide (NO) synthase, in particular asymmetric dimethylarginine (ADMA), are currently considered of importance in various disease states characterized by reduced NO availability. We investigated the association between plasma levels of ADMA, symmetric dimethylarginine (SDMA), L-arginine, and citrulline and perinatal factors and outcome in 130 preterm (gestational age ≤ 30 weeks) very low birth weight (VLBW, < 1500 g) infants. Plasma samples were collected 6-12 h after birth. We did not find significant correlations between ADMA, SDMA, L-arginine, and citrulline levels and gestational age or birth weight. However, the arginine:ADMA ratio (AAR, a better indicator of NO availability than either arginine or ADMA separately) was positively correlated wi
