Comment on 'Fatal, incidental, idiopathic pulmonary fibrosis in a patient receiving long-term low-dose methotrexate for psoriasis': reply from author

There appears to be some overlap in pathogenetic mechanisms between psoriasis and idiopathic pulmonary fibrosis e.g. raised IL-17; indeed, the possibility of a restrictive form of psoriatic lung disease has been raised although it appears to be rare. Patients with psoriasis may be at increased risk of developing interstitial lung disease (most commonly idiopathic pulmonary fibrosis) independent of previous or concomitant exposure to immunosuppressant therapy.
