Overview

Pathophysiology

Pulmonary fibrosis has often been called an autoimmune disease. However, it is perhaps better characterized as an abnormal and excessive deposition of fibrotic tissue in the pulmonary interstitium with minimal associated inflammation.[1] Autoantibodies, a hallmark of autoimmune diseases, are found in a minority of patients with truly idiopathic pulmonary fibrosis. Moreover, many autoimmune diseases associated with "pulmonary fibrosis", such as scleroderma, are more frequently associated with a related but more inflammatory disease, nonspecific interstitial pneumonitis.[2] It is associated with smoking[3] and exhibits some dependency on the amount of smoking.[4]
