Abstract |
Fibrillary glomerulonephritis is an unusual kidney disease characterized by the deposition of immunoglobulins in a fibrillar pattern. Until recently it has been considered to involve the kidneys alone. We describe a patient who underwent renal transplantation and developed fibrillary glomerulonephritis with rapidly progressive renal failure and severe pulmonary hemorrhage two years and a half after transplantation. Nephropathy prior to transplantation was thought to be focal and segmental glomerulosclerosis. Diagnosis of fibrillary glomerulonephritis in renal allograft was confirmed by postmortem examination. 50% of the glomeruli with extracapillary crescents were observed on light microscopy. By immunofluorescence main deposition of IgA was detected in the glomerular capillar walls and the mesangium. Electron microscopy showed fibrillo-reticular deposits in the same place. Lung histology showed both old and recent areas of alveolar hemorrhage. Granular staining for IgA was observed in the alveolar walls by immunofluorescence. Ultrastructural analysis of the lung made evident fibrillo-reticulary deposits in the interstitium, similar than those observed in the glomeruli. The presence of these deposits in both renal and pulmonary tissues indicates the possibility of systemic involvement in fibrillary glomerulonephritis. In our case it could be related to the recurrence of this glomerulopathy in renal allograft.
