Methotrexate therapy for psoriasis did not significantly impact lung function. Studies found no adverse effects on pulmonary function or arterial blood gas values in patients undergoing treatment.

Area of Science:

  • Pulmonology
  • Dermatology
  • Pharmacology

Background:

  • Methotrexate is a known inducer of pulmonary fibrosis.
  • Psoriasis patients may be at risk for methotrexate-induced lung toxicity.
  • Assessing pulmonary function in patients on methotrexate is crucial.

Purpose of the Study:

  • To evaluate pulmonary toxicity in psoriasis patients receiving methotrexate.
  • To correlate methotrexate dose and duration with pulmonary function changes.
  • To determine the safety of methotrexate therapy for lung health in psoriasis.

Main Methods:

  • Lung function studies were performed on two groups of psoriasis patients.
  • One group had taken methotrexate for one year; the other was currently receiving treatment.

  • Arterial blood gas analysis and detailed pulmonary function tests were conducted.

    • Main Results:

    • A non-significant decline in FEF200-1200, FEF25-75%, residual volume (RV), and RV/TLC% was observed after six months.
    • No significant changes in arterial blood gas values were detected.
    • Overall, no significant deterioration in lung function was found.

    Conclusions:

    • Methotrexate therapy for psoriasis does not appear to cause significant pulmonary toxicity.
    • Lung function remains stable in psoriasis patients undergoing methotrexate treatment.
    • Further long-term studies may be warranted to confirm these findings.
