    Abstract:
    This is a very rare case report of Goodpasture's syndrome with IgA antibasement membrane antibody. A 43-year old male was admitted because of severe dyspnea with slight hemoptysis. Chest X-ray demonstrated extensive bilateral infiltrates with air bronchogram, predominantly in the right lung. Laboratory data on admission showed severe anemia and moderate renal impairment. The pulmonary infiltrates resolved spontaneously within 10 days. Goodpasture's syndrome or collagen vascular disease was suspected and he underwent a percutaneous renal and transbronchial lung biopsy. The renal biopsy showed crescent formation affecting 70-80% of glomeruli. Linear IgA deposits, but not IgG, were demonstrated along the glomerular basement membrane by the direct immunofluorescence procedure. The lung biopsy contained many hemosiderin-laden macrophages in the lumen of the alveoli and showed mild thickening of alveolar walls. However, linear immunoglobulin deposits on the alveolar capillary basement membrane were not demonstrated by direct immunofluorescence. The diagnosis of Goodpasture's syndrome with IgA antibasement membrane antibody was made. His serum was negative for antibasement antibody by indirect immunofluorescence. He was treated with prednisone, 30 mg daily. His pulmonary symptoms and anemia improved markedly, but his renal function did not change. Thirteen months after his first admission, he suffered from severe bacterial pneumonia, which was complicated by disseminated intravascular coagulation. He died of respiratory failure. Autopsy was rejected.
