Antimicrobial factors in human milk.

V Reddy, C Bhaskaram, N Raghuramulu

    Acta Paediatrica Scandinavica
    |March 1, 1977
    PubMed
    Summary

    Maternal nutritional status and iron supplementation do not significantly impact key antibacterial factors like immunoglobulins, lactoferrin, and lysozyme in breast milk. These essential milk components remain consistent regardless of the mother's diet or iron intake.

    Area of Science:

    • Immunology
    • Nutritional Science
    • Human Lactation

    Background:

    • Breast milk contains crucial antibacterial factors like immunoglobulins, lactoferrin, and lysozyme.
    • Maternal nutrition is hypothesized to influence the composition of these protective elements in breast milk.
    • The role of iron supplementation in modulating these factors requires further investigation.

    Purpose of the Study:

    • To quantify immunoglobulins, lactoferrin, and lysozyme in breast milk from Indian women with varying nutritional status.
    • To assess the impact of lactation stage on these antibacterial factors.
    • To determine the effect of iron supplementation on lactoferrin levels and function.

    Main Methods:

    • Milk samples were collected from well-nourished and under-nourished Indian women at different lactation stages.

  • Levels of immunoglobulins, lactoferrin, and lysozyme were measured.
  • Iron administration effects were evaluated in a subset of participants.

    • Main Results:

    • Immunoglobulin and lactoferrin concentrations were higher in colostrum compared to mature milk.
    • Lysozyme levels increased progressively throughout lactation.
    • No significant differences were observed in antibacterial factor levels between nutritional groups.
    • Iron supplementation did not alter total or saturated lactoferrin levels.

    Conclusions:

    • Breast milk antibacterial factors are robust and not significantly affected by maternal nutritional status in the studied population.
    • Iron supplementation does not interfere with the bacteriostatic properties of lactoferrin in human milk.
    • Lactation stage influences the concentration of specific antibacterial components in breast milk.
