- W1981807290 abstract "Objectives To evaluate whether hepcidin concentrations in serum (Hep(S)) and urine (Hep(U)) correlate with iron metabolism, erythropoiesis, and inflammation in preterm infants. Study design Thirty-one preterm infants (23-32 weeks gestational age) were included. The concentration of the mature, 25 amino-acid form of hepcidin was determined by enzyme-linked immunosorbent assay in serum, urine, blood counts, reticulocytes, and iron measurements. Results Median (IQR) Hep(S) was 52.4 (27.9-91.9) ng/mL. The highest values were measured in patients with systemic inflammation. Hep(S) and Hep(U) correlated strongly (P = .0007). Hep(S) and Hep(U) also correlated positively with ferritin (P = .005 and P = .0002) and with reticulocyte hemoglobin content (P = .015 and P = .015). Hep(S) and Hep(U) correlated negatively with soluble transferrin receptor/ferritin-ratio (P = .005 and P = .003). Infants with lower hemoglobin concentrations and higher reticulocyte counts had lower Hep(S) (P = .0016 and P = .0089). Conclusion In sick preterm infants, iron status, erythropoiesis, anemia, and inflammation correlated with the mature 25 amino-acid form of hepcidin. Further evaluation of Hep(U) for non-invasive monitoring of iron status in preterm infants appears justified.
