    A control study found no change in delayed hypersensitivity to PPD, Candida, or tetanus antigens. However, responses to mumps antigen decreased, while SKSD antigen showed a significant booster effect, impacting immunomodulation research.

    Area of Science:

    • Immunology
    • Pharmacology

    Background:

    • A pilot study suggested a drug could augment delayed hypersensitivity.
    • Delayed hypersensitivity is a critical immune response.

    Purpose of the Study:

    • To investigate the effect of a drug on delayed hypersensitivity.
    • To validate findings from a pilot study in a controlled setting.

    Main Methods:

    • A control study involving 19 normal volunteers.
    • Application of a standardized skin test battery on two separate occasions.
    • No intervening treatment between skin tests.

    Main Results:

    • No significant change in delayed hypersensitivity response to purified protein derivative (PPD), Candida, or tetanus antigens.

  • A significant decrease in response to mumps antigen.
  • A marked augmented response (booster effect) to streptokinase-streptodornase (SKSD) antigen.

    • Conclusions:

    • The drug did not consistently augment delayed hypersensitivity across all antigens.
    • Specific antigen responses (mumps, SKSD) were altered, suggesting complex immunomodulatory effects.
    • Findings have implications for understanding immunomodulation and delayed hypersensitivity mechanisms.
