Variety of lung involvement in autoimmune liver diseases.

The primary autoimmune liver diseases conventionally include primary biliary cholangitis, primary sclerosing cholangitis and autoimmune hepatitis. Despite of primary autoimmune affection of different parts of the hepatobiliary system, in the recent decades, a lot of data has emerged indicating the presence of extrahepatic manifestations of these diseases, in particular, lung lesions, such as nodular and interstitial changes with possible progression and development of fibrosis and respiratory failure. In case of lungs disease, both pulmonary parenchyma and lung vessels, pleura, and intrathoracic lymph nodes can be involved. The most sensitive and specific procedure to assess the extent of the lung lesions and their evolution is high-resolution computed tomography. Due to the possibility of long-term asymptomatic course of the pulmonary disease with development of irreversible changes in patients with autoimmune liver diseases, it seems reasonable to conduct screening studies aimed at early detection and treatment of lung lesions in this population.
