Maternal Reticulocyte Hemoglobin as a Predictor of Neonatal Iron Deficiency and Anemia

Area of Science:

• Obstetrics and Gynecology
• Neonatology
• Hematology

Background:

• Anemia affects 30-40% of pregnancies globally, with iron deficiency (ID) being the primary cause.
• Iron deficiency anemia (IDA) impacts both maternal and fetal health.
• Reticulocyte hemoglobin equivalent (RET-He) offers a non-invasive method to assess functional iron status.

Purpose of the Study:

• To evaluate the utility of RET-He in identifying pregnant women and neonates at risk for ID and IDA.
• To assess the correlation between maternal and neonatal iron status markers.

Main Methods:

• Prospective, observational study of 177 pregnant women with anemia.
• Measurement of maternal hemoglobin (HgB) and RET-He in the first and third trimesters.
• Measurement of neonatal cord blood HgB and RET-He at delivery.

Main Results:

• Maternal RET-He did not predict neonatal anemia but showed improved prediction for neonatal ID in the third trimester.
• Maternal ID diagnosed by RET-He was associated with anemia during pregnancy.
• Most neonates presented with normal HgB and RET-He values.

Conclusions:

• Maternal RET-He is not a reliable predictor of neonatal anemia.
• RET-He can aid in earlier diagnosis of maternal ID, even without anemia.
• RET-He monitoring may be beneficial for pregnant women diagnosed with IDA.
