Dapsone hypersensitivity syndrome, a rare side effect, can manifest with severe symptoms. This case highlights the crucial role of monitoring for transient circulating T-cell clones in managing these reactions.

Area of Science:

  • Pharmacology
  • Immunology
  • Dermatology

Background:

  • Dapsone is a medication with rare but serious hypersensitivity side effects.
  • Hypersensitivity reactions can involve skin manifestations, lymphadenopathy, and liver dysfunction.

Observation:

  • A 45-year-old woman developed dapsone hypersensitivity during treatment for asthma.
  • A transient circulating T-cell clone was detected during the acute phase of the reaction.

Findings:

  • Clinical symptoms and laboratory abnormalities resolved with corticosteroid treatment.
  • Hypersensitivity reactions recurred upon corticosteroid tapering, indicating a complex immune response.

Implications:

  • The presence of a transient circulating T-cell clone underscores the immunological basis of dapsone hypersensitivity.
