In this study of patients with suspected drug-induced interstitial lung diseases, 60% had potential risk factors for developing drug-induced interstitial lung diseases.

Our results indicate that the occurrence of drug-induced pulmonary toxicity is at least partly linked to inter-patient variation in genes and drug use.

The results highlight the importance of considering both drug use and genetic make-up as possible causes, or at least contributing factors, in the development and/or progression of fibrotic lung diseases.
