Ischemia‐modified albumin in preterm infants born to mothers with pre‐eclampsia.

Abstract: Background: Pre‐eclampsia (PE) carries an increased risk for maternal and/or fetal mortality or serious morbidity. PE is associated with ischemia and increased oxidative stress in the placenta, which may lead to modification of plasma albumin to ischemia‐modified albumin (IMA). The aim of this study was to investigate IMA and hematological parameters in mothers and in premature infants in normal and in pre‐eclamptic pregnancies. Methods: Twenty‐five pregnant women with PE and their premature newborns were categorized as the PE group, and 25 normotensive pregnant women and their premature newborns as the control group. Preterm infants are classified as small for gestational age (SGA) or non‐SGA according to the Fenton preterm growth chart. Serum IMA, complete blood count (CBC), liver function tests (LFT), renal function tests (RFT), albumin, and C‐reactive protein were measured in the mothers immediately before birth, and in the cord blood and serum of the newborns at 6 and 24 h after birth. Clinical and demographic data were recorded for both groups. Results: While IMA, LFT and RFT were significantly increased in the PE group compared with the control group, albumin and CBC were significantly lower in the PE group. A total of 40% of PE newborns were SGA, 30% of whom had severe SGA (birthweight <3rd percentile). Cord IMA was significantly increased in all preterm neonates in the PE group compared with the control group. No mothers or neonates died. Conclusion: Serum IMA in addition to the prevalence of SGA were significantly increased in the PE group. Cord blood IMA, therefore, might be a predictive biomarker for SGA in PE pregnancies.
