The frequency, clinical presentation, prognosis and response to therapy vary depending on the histological pattern (usual interstitial pneumonia, desquamative interstitial pneumonia, organising pneumonia, diffuse alveolar damage, nodular lesions, etc.), as well as on the underlying CVD (scleroderma, rheumatoid arthritis, systemic lupus erythematosus, dermatopolymyositis, Sjögren's syndrome or mixed connective tissue disease).
The diagnosis of most of these CVDs is based on a number of criteria; in several of these, however, lung involvement is not part of the diagnostic criteria. In addition, there may be overlaps between several of these CVDs.
Optimal treatment varies depending on the type of collagen vascular disease and the presence of interstitial lung disease, although in many cases, a combination of corticosteroids and cytostatic drugs are given.
