    Aspirin did not significantly affect delayed hypersensitivity responses in healthy individuals. Immune cell function and skin test results remained unchanged after aspirin or placebo treatment.

    Area of Science:

    • Immunology
    • Pharmacology

    Background:

    • Delayed hypersensitivity is a critical immune response.
    • Aspirin's immunomodulatory effects require further investigation.

    Purpose of the Study:

    • To evaluate the impact of aspirin on delayed hypersensitivity in healthy subjects.
    • To assess aspirin's effects on lymphocyte proliferation and T-lymphocyte percentages.

    Main Methods:

    • Double-blind, placebo-controlled study with 40 healthy participants.
    • Aspirin (4 gm daily) or placebo administered for 5 days.
    • Measurements included lymphocyte proliferation, T and B lymphocyte percentages, and antigen skin testing.

    Main Results:

    • No significant differences observed in skin test reactions between aspirin and placebo groups.

  • Lymphocyte proliferation assays showed no significant variations between groups.
  • Percentages of T lymphocytes did not differ significantly between the aspirin and placebo groups.

    • Conclusions:

    • Aspirin administration did not alter delayed hypersensitivity responses in this cohort.
    • The study suggests aspirin has no significant impact on key cellular immune markers related to delayed hypersensitivity.
