Apoptosis resistant bronchoalveolar lavage (BAL) fluid lymphocytes in sarcoidosis.
BACKGROUND Sarcoidosis is a chronic granulomatous lung disease of unknown origin. The accumulation of activated T cells at sites of inflammation represents an early stage in granuloma formation. Since mechanisms governing the normal resolution of inflammatory processes are poorly understood, this study aimed to investigate the apoptotic phenotype of peripheral blood and lung T lymphocytes from ...
متن کاملBronchoalveolar lavage in gold lung.
We report the results of bronchoalveolar lavage in a patient with gold salt-induced interstitial pneumonitis. The presence of elevated numbers of lymphocytes in the lavage specimen supports a hypersensitivity-related pathogenesis of this disease. Such findings may help distinguish pulmonary complications of gold therapy from interstitial disease due to rheumatoid arthritis.
متن کاملBronchoalveolar Lavage (BAL) for Research; Obtaining Adequate Sample Yield
We describe a research technique for fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) using manual hand held suction in order to remove nonadherent cells and lung lining fluid from the mucosal surface. In research environments, BAL allows sampling of innate (lung macrophage), cellular (B- and T- cells), and humoral (immunoglobulin) responses within the lung. BAL is internationally acce...
متن کاملBronchoalveolar lavage in talc induced lung disease.
A 65 year old woman with a history of occupational talc inhalation presented with hypoxaemia, cough, and dyspnoea with a normal chest radiograph. Bronchoalveolar lavage showed considerable lymphocytosis, with a predominance of T8+ T lymphocytes, and open lung biopsy showed peribronchiolar granulomas containing talc crystals. Corticosteroid treatment resulted in dramatic improvement. Bronchoalve...
متن کاملBronchoalveolar lavage in occupational lung diseases.
Occupational lung diseases (OLDs) are related to the exposure and inhalation of organic, inorganic, and synthetic particles, fumes, gases, or infectious agents. From the long list of OLDs this article focuses the discussion on bronchoalveolar lavage (BAL) in parenchymal immunoinflammatory conditions, such as hypersensitivity pneumonitis (HP) and pneumoconiosis. Several antigens may cause HP, in...
