Nonasthmatic Case of Churg-Strauss Syndrome with Rapidly Progressive Glomerulonephritis

Abstract

A 61-year-old man developed mononeuritis multiplex accompanied by eosinophilia in 1993. Approximately 3 years later, acute renal dysfunction, a subendocardial tumor, and a high peripheral anti-neutrophil cytoplasmic antibody titer were also detected. Renal biopsy revealed glomerular crescents and interstitial infiltration of eosinophils, so allergic granulomatosis and angiitis was diagnosed. These clinical abnormalities regressed with steroid therapy. He had no history of asthma. This was therefore considered to be an atypical form of Churg-Strauss syndrome with rapidly progressive glomerulonephritis.
