  • Title: Erythropoiesis: Correlations Between Iron Status Markers During Normal Pregnancy in Women with and without Iron Supplementation.
    Author: Byg KE, Milman N, Ole Agger A.
    Journal: Hematology; 2000; 4(6):529-539. PubMed ID: 11399596.
    Abstract:
    The aim was to evaluate relationships between iron status markers (haemoglobin, erythrocyte indices, serum iron, serum transferrin, serum transferrin saturation, serum ferritin) in normal pregnancy. Iron status markers were measured at 4-week-intervals during pregnancy and postpartum in 120 healthy women; 62 had daily treatment with tablets containing 66 mg ferrous iron, 58 were treated with placebo. Placebo-treated: Ferritin displayed positive correlations with transferrin saturation during 2nd and 3rd trimester. There were positive correlations between ferritin, erythrocyte MCV and MCH during 2nd and 3rd trimester and postpartum. Prior to delivery and postpartum, ferritin demonstrated positive correlations with haemoglobin. Transferrin saturation showed positive correlations with MCV, MCH and MCHC during 2nd and 3rd trimester and postpartum. Transferrin saturation displayed positive correlations with haemoglobin prior to delivery and postpartum. Iron-treated: In general, there were no correlations between iron status markers. Positive correlations appeared postpartum between ferritin, transferrin saturation and MCHC but not with haemoglobin. Transferrin saturation showed a positive correlation with MCH postpartum, but not with haemoglobin. Conclusion: The patterns of relationships in placebo-treated women were consistent with iron deficient erythropoiesis.
