    Abstract:
    This article describes a case of Goodpasture's syndrome controlled by double filtration plasmapheresis (DFPP) combined with steroid and immunosuppressant therapy. A 48-year-old male, clerk, complaining of fever, dry cough and macroscopic hematuria, was admitted to our hospital. Microscopic hematuria was first pointed out at age 40 on an annual check up. His laboratory data on admission revealed severe anemia, azothemia, macroscopic hematuria and proteinuria. His chest radiograph and CT revealed diffuse nodular densities in bilateral lung fields. Specimens obtained by transbronchial lung biopsy and open renal biopsy revealed linear deposition of IgG by direct immunofluorescent antibody methods. Circulating antiglomerular basement membrane antibody level determined with radioimmunoassay was 1.8% on admission, but one week later it elevated to 5.6% with progression of dyspnea, hypoxemia, and renal failure. Steroid pulse therapy and a total of 6 double filtration plasmaphereses were performed in the first month. Subsequently hypoxemia and dyspnea disappeared, and the chest radiograph of the 40th hospital day showed no abnormal shadows. Two months later recurrence of pulmonary hemorrhage was noticed. Immunosuppressant administration (Cyclophosphamide 100 mg/day) and a total of 10 DFPP procedures were performed with success. By DFPP, circulating anti-GBM antibody fell rapidly to within normal ranges, and anti-GBM antibody level elevated in removed plasma. We think DFPP is effective to remove circulating anti-GBM antibody in Goodpasture's syndrome.
