Autoimmune Aspects of Lung Disease

Springer Book Archives

The lung and its contiguous structures are commonly involved in several of the rheumatic diseases (Table 1), either by direct manifestation of disease or as a secondary effect from infection or complications of therapy. In this chapter, we detail the various pulmonary manifestations of the major rheu- matological conditions. The common symptoms of pulmonary diseases and how frequently they are implicated in rheumatic disorders are review- ed. In addition, radiology and physiology of the lung, diagnostic proce- dures and therapeutic options are discussed. Table l.

Respiratory Symptoms The most common respiratory symptoms in patients with rheumatic disease and pulmonary involvement are non-specific and include cough, breathlessness and chest pain and can be the result of involvement of air- ways, lung parenchyma, pleura, chest wall or pulmonary vessels. 1. 3.
