Y1 - 2023 N1 - T2 - Fishman’s Pulmonary Diseases and Disorders, 6e AB - Pleuropulmonary involvement associated with the collagen vascular diseases occurs frequently. All the structures within the respiratory tract may be affected, either separately or in combination. This includes the respiratory muscles, the pleura, the conducting airways, and the lung parenchyma—the small airways, the interstitium, or the pulmonary vessels. Patients with underlying collagen vascular disease experience an increased incidence of community-acquired pneumonia, as well as pneumonia associated with the immunosuppressive drugs employed for treatment. Anti–tumor necrosis factor α (anti–TNF-α) agents increase the risk for infections, particularly typical and atypical mycobacterial pathogens (e.g., tuberculous and nontuberculous), Pneumocystis jirovecii, and Nocardia species. Cytotoxic drugs, particularly methotrexate and gold, also can induce various noninfectious interstitial reactions, which are often difficult to distinguish from a primary interstitial complication of a collagen vascular disease.1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/24 UR - accessmedicine.mhmedical.com/content.aspx?aid=1195006272 ER -
