Cell-mediated immunity in measles using the leucocyte migration test.

H N Desai, J Strashoon, A Wesley

    International Archives of Allergy and Applied Immunology
    |January 1, 1978

    Summary

    Children with acute measles showed temporary anergy in cell-mediated immunity tests. While in vivo tests revealed universal anergy, in vitro tests distinguished between reactors and non-reactors, suggesting complex immune responses during measles infection.

    Area of Science:

    • Immunology
    • Pediatrics
    • Virology

    Background:

    • Measles is a viral illness known to transiently suppress cell-mediated immunity.
    • Understanding the specific immune defects during measles is crucial for managing complications.

    Purpose of the Study:

    • To investigate the cell-mediated immune response in children with acute measles.
    • To compare immune responses between children with measles and healthy controls.

    Main Methods:

    • Utilized intradermal Heaf tests (in vivo) and leucocyte migration tests (in vitro) on 21 children with acute measles and 8 healthy children.
    • Employed tuberculin and purified protein derivative as antigens to assess cellular immune function.

    Main Results:

    Related Experiment Videos

  • All children with acute measles exhibited anergy in the in vivo Heaf test.
  • The in vitro leucocyte migration test allowed for the differentiation of measles patients into 'reactors' and 'non-reactors'.

    • Conclusions:

    • Acute measles infection induces a significant, albeit potentially transient, anergy in cell-mediated immunity.
    • In vitro assays provide a more nuanced view of immune status during measles compared to in vivo tests, highlighting distinct immune profiles within the patient group.
