[A case of Goodpasture's syndrome with myeloperoxidase specific anti-neutrophil cytoplasmic autoantibody (MPO-ANCA) during chronic interstitial pneumonia].
A 55-year-old man was admitted to our hospital with of hemoptysis, progression of anemia and renal failure in February, 1996. Idiopathic interstitial pneumonia had been diagnosed and he had been followed at a regional hospital since 1988. On the third day after admission, he suffered from sudden and massive hemoptysis. Goodpasture's syndrome was diagnosed because anti-GBM antibody was detected in serum. A high titer of MPO-ANCA was also recognized simultaneously. Steroid pulse therapy, immunosuppressive therapy, and plasmapheresis were begun, but he died on the 28th hospital day because of severe hypoxemia and multi-organ failure. Histological examination after autopsy revealed crescentic glomerulonephritis with linear deposition of IgG in the glomerular capillary wall, and interstitial pneumonia accompanied by massive alveolar hemorrhage. It was suggested that in this patient, not only anti-GBM antibody but also circulating MPO-ANCA might have participated in the progression of the crescentic glomerulonephritis and alveolar hemorrhage observed in Goodpasture's syndrome.
