To determine the prevalence of pulmonary dysfunction in lupus erythematosus, 24 patients with systemic lupus erythematosus (SLE) and 5 patients with discoid lupus erythematosus (DLE) were studied. Diffusing capacity for carbon monoxide was abnormal in 17 (71 percent) SLE patients. A restrictive ventilatory defect was present in 6 (25 percent) and arterial(More)
Several systemic diseases share clinical, pathologic and radiologic characteristics. This article emphasizes similarities and differences in the clinical and chest radiographic manifestations of six diseases with both pulmonary and renal abnormalities-Goodpasture's syndrome, Wegener's granulomatosis, lymphomatoid granulomatosis, Churg-Strauss syndrome,(More)
Numerous systemic diseases share immunopathogenic mechanisms. This article reviews the proposed etiologies and immunopathogenic mechanisms of a group of diseases which share pulmonary and renal abnormalities. Specifically, we discuss the following diseases: Good-pasture's syndrome, systemic lupus erythematosus, progressive systemic sclerosis, Wegener's(More)
Angiotensin I convertase activity has been found in human alveolar macrophages from normal volunteers and patients with pulmonary sarcoidosis. This activity is higher in the alveolar macrophages from smokers than from nonsmokers, and is even more elevated in sarcoid patients. The activity can be detected with both angiotensin I and bradykinin analogs and(More)
