Metabolic bone disease in preterm infants.

N Beyers, F S Hough

    South African Medical Journal = Suid-Afrikaanse Tydskrif Vir Geneeskunde
    |September 27, 1986
    PubMed
    Summary

    Preterm infants require calcium, phosphorus, and vitamin D supplementation to prevent bone diseases like osteopenia and rickets. These nutrients are crucial for proper bone mineralization in early development.

    Area of Science:

    • Neonatology
    • Pediatric Bone Health
    • Nutritional Science

    Background:

    • Preterm infants are susceptible to bone abnormalities, including osteopenia, rickets, and fractures.
    • The exact relationship between these bone abnormalities is not fully understood.
    • Adequate calcium and phosphate accretion, crucial for bone mineralization, is challenging to achieve through standard postnatal feeding for preterm infants.

    Purpose of the Study:

    • To investigate the necessity of supplementation for preventing bone abnormalities in preterm infants.
    • To explore the role of calcium, phosphorus, and vitamin D in neonatal bone health.
    • To understand the impact of postnatal nutrition on bone mineralization in small preterm babies.

    Main Methods:

    • Review of current understanding of bone mineralization in preterm infants.
    • Analysis of nutritional requirements versus intake from breastmilk and conventional formulas.
    • Discussion of the role of vitamin D and other calciotrophic hormones in bone development.

    Main Results:

    • Normal intra-uterine mineral accretion rates exceed those achievable with standard preterm infant feeding.
    • Supplementation with calcium, phosphorus, and vitamin D is indicated to prevent neonatal osteopathy.
    • Vitamin D likely enhances intestinal absorption of calcium and phosphorus, potentially influencing bone growth directly.

    Conclusions:

    • Supplementation is essential for preventing bone issues in preterm infants.
    • Optimizing mineral and vitamin D intake is critical for neonatal bone health.
    • Further research may clarify the specific roles of vitamin D and other hormones in preterm bone growth.
