[Idiopathic interstitial pneumonias]

The article presents the evolution of views on one of the current problems of present pulmonology idiopathic interstitial pneumonias. On the basis of many years of experience in diagnosis and treatment of patients of IIPs in the clinic of pulmonology of Interstitial and Orphan Lung Diseases Research Institute of Pavlov First Saint Petersburg State Medical University, the authors formulated a new understanding of this pathology and proposed to unite all IIPs under the term idiopathic fibrosing pulmonary disease. Using the concept of idiopathic fibrosing pulmonary disease will make it possible to substantively address the issues of early diagnosis, determine the criteria for the activity of the pathological process, and there by develop an evidence base for the adequate prescription of antifibrotic drugs and corticosteroids.
