Interferon therapy can trigger sarcoidosis, an immune disorder. This review of 65 cases shows IFN-induced sarcoidosis often affects lungs and skin, typically resolves after stopping treatment, and presents later in life.

Area of Science:

  • Immunology
  • Dermatology
  • Pulmonology

Background:

  • Interferons (IFNs) are used to treat various diseases and possess immunomodulatory effects.
  • IFN therapy is linked to autoimmune conditions, including sarcoidosis.
  • IFN-induced sarcoidosis (IIS) is an emerging concern.

Purpose of the Study:

  • To review the literature on IIS, summarizing 65 reported cases.
  • To highlight the pathophysiology, clinical features, diagnostics, and therapeutics of IIS.
  • To increase awareness of this recognized phenomenon.

Main Methods:

  • Literature review of 65 reported cases of IIS.
  • Analysis of clinical presentations, organ involvement, and treatment outcomes.
  • Case report illustrating typical IIS presentation and resolution.

Main Results:

  • IIS onset is typically later than naturally occurring sarcoidosis.
  • The lungs and skin are the most commonly affected organs.
  • IIS generally follows a benign course with complete resolution after IFN discontinuation.

Conclusions:

  • IIS is an important consideration in patients receiving IFN therapy.
  • Early recognition and discontinuation of IFN can lead to favorable outcomes.
  • Further research into the mechanisms and management of IIS is warranted.
