A significant proportion - up to 40 % - of patients suffering from fibrosing interstitial pneumonia will acquire a progressive phenotype which shares genetic and pathogenic mechanisms, as well a clinical behavior similar to those of idiopathic pulmonary fibrosis (IPF). It therefore makes sense to suggest that molecules with antifibrotic properties such as pirfenidone and nintedanib could be effective in patients with progressive fibrosing interstitial lung disease as they are in patients with IPF. The first studies published on this topic show encouraging results which however have to be confirmed on a larger scale.
