[Simultaneous presence of antibodies against the glomerular basement membrane and anti-myeloperoxidase antibodies in 2 patients with rapidly progressive glomerulonephritis].
We report two patients with rapidly progressive glomerulonephritis without alveolar hemorrhage. Renal biopsy showed extracapillary glomerulonephritis with linear deposits of immunoglobulin G. Serologically anti-glomerular basement membrane antibodies (Ac AMBG) and ANCA anti-myeloperoxidase were present. All patients were treated with steroids, cyclophosphamide and plasma exchange. One patient needed dialysis, and other one died from a renal biopsy complication. We discuss the epidemiologic, pathogenic and prognostic aspects of this association.
