Diagnosis and treatment of interstitial lung disease in scleroderma systematica

Abstract

Scleroderma systemitica (SDS) is an autoimmune connective tissue disease characterized by excessive fibrosis of the skin and viscera. SDS is prone to be chronic and progressive, is accompanied by the deterioration in quality of life and working ability and has an unfavorable prognosis. Interstitial lung disease (ILD) is one of the most common causes of death due to SDS.The lecture deals with the clinical and laboratory instrumental features of ILD in SDS. SDS-associated ILD occurs in 65–80% of patients and is highly diverse in the degree of severity and the tendency to progression. In the majority of patients, the fibrous process in the lung occurs in the early years of the disease, is limited and progresses slowly. Severe lung damage with rapid progression develops only in 10–15% of cases. Evaluation of lung damage in SDS includes pulmonary function tests, lung diffusing capacity determination, Doppler echocardiography analysis, multispiral computed tomography (MSCT) of the chest, bronchoalveolar lavage, lung biopsy with morphological examination of its specimens, as well as right heart catheterization. The best technique for detecting ILD is MSCT, as chest radiography has a low sensitivity in the early stages of the disease. IPL is treated in accordance with the 2017 ACR/EULAR guidelines; the leading role is played by immunosuppressive drugs, such as cyclophosphamide and mycophenolate mofetil. Antifibrotic drugs (pirfenidone, nintedanib) are being tested now .
