Abstract/OtherAbstract:
Objective:To determine whether B-type natriuretic peptide (BNP) levels in umbilical cord blood (UCB) and amniotic fluid (AF) are correlated with birth-weight discordances in monochorionic-diamniotic twins.Study Design:The UCB-BNP and AF-BNP levels were determined at birth in 36 twin-pairs without twin-twin transfusion syndrome (TTTS).Result:Both the UCB-BNP and the AF-BNP levels were significantly higher among twins with either a birth-weight discordance 20% (141.6 versus 52.9 pg ml(-1) for UCB-BNP, 38.0 versus 17.2 pg ml(-1) for AF-BNP) or cardiac dysfunction at birth (167.2 versus 56.3 pg ml(-1) for UCB-BNP, 34.9 versus 19.0 pg ml(-1) for AF-BNP), compared with neonates without the respective characteristics. The UCB-BNP and AF-BNP levels in both the larger and the smaller twins were significantly correlated with birth-weight discordance.Conclusion:Cardiac dysfunction occurs in both larger and smaller co-twins with increasing birth-weight discordances, even in the absence of TTTS.Journal of Perinatology advance online publication, 12 July 2012; doi:10.1038/jp.2012.94.
