A patient with myeloma developed acute interstitial pneumonia after stopping corticosteroids. Prompt steroid treatment and drug cessation led to recovery, suggesting a hypersensitivity reaction.

Area of Science:

  • Pulmonology
  • Oncology
  • Pharmacology

Background:

  • Multiple myeloma is a hematologic malignancy.
  • Melphalan is a chemotherapeutic alkylating agent used in myeloma treatment.
  • Corticosteroids are often used in myeloma management and can have immunosuppressive effects.

Observation:

  • A patient with myeloma on melphalan therapy developed acute interstitial pneumonia with hypoxemia after corticosteroid cessation.
  • Bronchoalveolar lavage revealed lymphocytosis and no microbial pathogens.
  • The patient showed rapid clinical improvement upon reintroduction of corticosteroids.

Findings:

  • The clinical presentation and diagnostic findings support a diagnosis of melphalan-induced pneumonia.
  • The acute onset and response to steroids suggest a hypersensitivity mechanism.

  • This acute form is distinct from previously reported sub-acute fibrosing pneumonitis associated with melphalan.

    • Implications:

    • Early recognition and treatment of melphalan-induced pneumonia with glucocorticoids are crucial.
    • Immediate and permanent discontinuation of melphalan is essential for patient prognosis.
    • Distinguishing this acute hypersensitivity reaction from chronic pneumonitis is vital for appropriate management.
