Abstract
AIM: We analyzed the N-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin T (cTnT) in non-immune hydrops cases, to determine whether congestive heart failure or inadequate cardiac output may be mechanisms underlying abnormal fluid collection in hydrops. METHODS: The study population consisted of singleton neonates with non-immune hydrops and healthy control neonates, matched for both gestational age at delivery and mode of delivery. The subjects were divided into three groups: group 1, hydrops of cardiac origin (n=6); group 2, hydrops of non-cardiac origin (n=17); and group 3, control (n=23). The NT-proBNP and cTnT were measured in the cord blood collected at the time of delivery. RESULTS: The median cord blood concentrations of NT-proBNP and cTnT were not different between the hydrops (groups 1 and 2) or control cases. However, the NT-proBNP level was elevated in group 1 compared with groups 2 and 3. The concentrations of cTnT did not differ among the three groups. CONCLUSIONS: The concentration of NT-proBNP was only elevated in cases of hydrops of cardiac origin. Congestive heart failure might not be the underlying mechanism of fluid collection in cases of non-immune hydrops of non-cardiac origin, and NT-proBNP may be a promising tool to differentiate the origin of hydrops.
