Lesions in lungs in patients with rheumatoid arthritis

The aim of this work was to study the prevalence and clinical features of affection of lungs and lower respiratory tract (LRT) in patients with rheumatoid arthritis (RA). A total of 104 non-smoking patients with RA and 100 ones without RA or chronic pulmonary diseases were examined. RA was associated with affection of all parts of the respiratory tract including proximal and distal bronchi, lung interstitium, and pleura. Bronchopulmonary disorders in RA patients had multilevel character suggesting continuous inflammation and sclerotization of anatomic respiratory structures. Lesions in lungs and LRT are shown to be of prognostic value (bronchiectasis, bronchiolitis, interstitial pneumonia), they frequently produce only weak clinical symptoms, and therefore need to be actively detected. Combination of functional tests and imaging techniques is of primary importance for diagnosis of respiratory problems in patients with RA.
