Serum ferritin, iron levels and iron binding capacity in asymmetric SGA babies.
The concentration of serum ferritin reflects the extent of iron stores in premature infants. We aimed to determine serum ferritin levels and iron status in asymmetric small for gestational age (SGA) babies. This study was performed on 21 SGA babies and 19 appropriate for gestational age (AGA) babies. Hemoglobin, iron, iron binding capacity and ferritin levels were investigated in the first six hours after the birth. Hemoglobin levels in the SGA and control groups were 20.9 +/- 1.3 (19.4-23.4 g/dl) and 19.6 +/- 0.8 (18.5-21.5 g/dl), respectively (p = 0.001). Serum ferritin levels in the SGA and AGA groups were 58.36 +/- 20.1 ng/ml and 90.46 +/- 30.5 ng/ml, respectively. Ferritin levels were found lower in the SGA group (p < 0.001). In the SGA group, decreased serum iron and increased iron binding capacity were found but the difference was not significant (p > 0.05). Decreased ferritin levels may result from either impaired iron transport associated with uteroplacental vascular insufficiency or increased iron utilization during enhanced erythropoiesis in conditions characterized by chronic fetal hypoxia. Our results stress the significance of iron supplementation and careful anemia follow-up in term SGA babies. Because anemia progress early, beginning iron therapy as soon as possible is a necessity in SGA babies as in prematures.
