Goodpasture's syndrome: two cases with contrasting early course and management.

In 2 patients with hemoptysis and hematuria, Goodpasture's syndrome was documented by clinical presentation, demonstration of circulating anti-glomerular basement membrane antibodies, and demonstration of linear immunofluorescence along glomerular and alveolar basement membranes. One patient was considered to have progressive disease and was treated with prednisone and cyclophosphamide. During the subsequent 18-month follow-up period, clinical remission occurred with eventual disappearance of hematuria and detectable circulating anti-glomerular basement membrane antibodies. The other patient did not have active hemoptysis at the time of referral and no therapy was instituted. After 12 months of follow-up, hemoptysis remains quiescent but hematuria and positive circulating anti-glomerular basement membrane antibodies persist. Although therapy appears to have been particularly effective in one patient, the benign course of the other patient precludes premature enthusiasm for early intervention.
