Summary

Synthetic retinoid isotretinoin may negatively impact lung function in systemic sclerosis patients. Further studies are needed to confirm these findings and assess risks for other conditions.

Area of Science:

  • Pulmonology
  • Dermatology
  • Rheumatology

Background:

  • Systemic sclerosis is a complex autoimmune disease affecting connective tissues.
  • Isotretinoin, a synthetic retinoid, is used to treat various dermatological conditions.
  • Potential adverse effects of isotretinoin on pulmonary function require investigation.

Purpose of the Study:

  • To evaluate the impact of isotretinoin on pulmonary function in patients with systemic sclerosis.
  • To compare lung function changes in isotretinoin-treated patients versus a control group.

Main Methods:

  • An open prospective study involving ten systemic sclerosis patients treated with isotretinoin.
  • Retrospective comparison of pulmonary function tests (PFTs) between treated patients and a matched control group.

  • Monitoring for adverse events such as pleural effusion and changes in PFTs.

    • Main Results:

    • One patient developed eosinophilic pleural effusion.
    • Two patients showed asymptomatic deterioration in pulmonary function tests.
    • Isotretinoin-treated patients exhibited a significantly greater decrease in 1-second forced expiratory volume (FEV1) and transfer coefficient compared to controls.

    Conclusions:

    • Isotretinoin treatment may be associated with adverse effects on lung function in systemic sclerosis patients.
    • Further research is warranted to investigate lung function changes in patients treated with isotretinoin for other indications.
    • Caution is advised when considering isotretinoin for systemic sclerosis patients with pre-existing pulmonary concerns.
