Serum pro-hepcidin levels and relationships with iron parameters in healthy preterm and term newborns.

Abstract:

:A recently isolated peptide hormone, hepcidin, is thought to be the principal regulator of iron homeostasis. Hepcidin acts by limiting intestinal iron absorption and promoting iron retention in reticuloendothelial cells. Its precursor peptide form is called pro-hepcidin. The aims of this study were to determine serum pro-hepcidin levels in healthy preterm and term newborns, and to assess possible relationships between pro-hepcidin and serum iron, serum ferritin, and transferrin. A serum sample was collected from each of 26 healthy preterm (gestational age < 37 weeks) and 16 healthy, full-term, appropriate-for-gestational age babies. The preterm babies were also divided into 2 subgroups based on gestational age. Samples were analyzed for complete blood count, serum iron and ferritin concentrations, iron-binding capacity, and transferrin and pro-hepcidin levels. Group findings were compared and correlations between pro-hepcidin and the iron parameters were tested. The respective serum pro-hepcidin levels (mean +/- SD) in the 16 healthy term and 26 healthy preterm newborns were 482 +/- 371.9 ng/mL and 496.7 +/- 443.5 ng/mL. Analysis revealed no significant correlations between serum pro-hepcidin level and serum iron, serum ferritin, or transferrin in the preterm or term newborns. Pro-hepcidin levels were not correlated with gestational age in the preterm group. The results indicate that healthy preterm and term newborns have high pro-hepcidin levels.
