Interleukin-1 in malnutrition.

P Bhaskaram, B Sivakumar

    Archives of Disease in Childhood
    |February 1, 1986

    Summary
    This summary is machine-generated.

    Severe malnutrition in children with kwashiorkor and marasmus significantly reduces interleukin-1 production by monocytes. Macrophages also showed impaired function, suppressing cellular immunity.

    Area of Science:

    • Immunology
    • Nutritional Science
    • Pediatrics

    Background:

    • Malnutrition is a global health issue affecting immune system development.
    • Impaired cellular immunity is a known complication of severe childhood malnutrition.

    Purpose of the Study:

    • To investigate the impact of kwashiorkor and marasmus on monocyte-derived interleukin-1 production.
    • To assess macrophage function and its role in cellular immunity suppression in malnourished children.

    Main Methods:

    • Monocytes were isolated from children with kwashiorkor, marasmus, and healthy controls.
    • Interleukin-1 production was measured in vitro following lipopolysaccharide stimulation.
    • Macrophage-mediated suppression of mouse thymocyte proliferation was assessed.

    Main Results:

    • Children with severe malnutrition exhibited significantly lower interleukin-1 activity.
    • Macrophages from children with kwashiorkor produced suppressive factors.
    • These findings indicate impaired macrophage function in severe malnutrition.

    Conclusions:

    • Severe malnutrition, specifically kwashiorkor and marasmus, impairs macrophage function.
    • Reduced interleukin-1 production and suppressive factors contribute to the compromised cellular immunity observed in malnourished children.
