Storage iron in human foetal organs.

P N Singla, V K Gupta, K N Agarwal

    Acta Paediatrica Scandinavica
    |September 1, 1985
    PubMed
    Summary

    Fetal iron stores increase with gestational age and birth weight. Maternal iron levels directly impact fetal iron stores, indicating preterm infants and those born to iron-deficient mothers have lower iron reserves.

    Area of Science:

    • Obstetrics and Gynecology
    • Pediatric Nutrition
    • Biochemistry

    Background:

    • Iron is crucial for fetal development.
    • Maternal iron status influences fetal iron accretion.
    • Understanding fetal iron storage is vital for assessing neonatal health.

    Purpose of the Study:

    • To quantify non-heme iron storage in fetal organs.
    • To correlate fetal iron stores with gestational age and birth weight.
    • To investigate the relationship between maternal plasma iron and fetal iron levels.

    Main Methods:

    • Analysis of maternal plasma iron levels.
    • Measurement of non-heme iron concentration in fetal liver, spleen, and kidney tissues.
    • Correlation analysis with gestational age, birth weight, and maternal iron status.

    Main Results:

    • Total fetal iron storage increased with gestational age and organ growth.
    • Liver iron content showed a significant increase in the final 8 weeks of gestation.
    • Positive correlations were found between fetal iron stores, birth weight, and gestational age.
    • Maternal plasma iron levels directly correlated with fetal liver iron concentration and total content.

    Conclusions:

    • Fetal iron stores accumulate progressively throughout gestation, particularly in the liver during late pregnancy.
    • Preterm infants and infants of iron-deficient mothers exhibit diminished iron stores at birth.
    • Maternal iron status is a key determinant of fetal iron accretion, highlighting the importance of adequate maternal nutrition.
