The lung is often the target of collagen vascular diseases (CVD), usually with interstitial pneumonia. The type of interstitial lung disease may be a clue to the diagnosis of CVD, and is sometimes very specific (UIP and rheumatoid arthritis, COP and dermatoymyositis, LIP and Sjogren's syndrome). The development of interstitial lung disease affects the prognosis of CVD (Pulmonary hypertension and systemic sclerosis, UIP and Rheumatoid arthritis). Interstitial lung disease associated with CVD usually has a better prognosis than idiopathic interstitial lung disease. Currently, there is no effective specific treatment for interstitial pneumonia associated with CVD except cyclophosphamide in systemic sclerosis.
