Fibrillary glomerulonephritis presenting as rapidly progressive renal failure in a young female: a case report

Int Urol Nephrol. 2005;37(3):561-4. doi: 10.1007/s11255-004-4707-3.

Abstract

Fibrillary Glomerulonephritis (FGN) is a rare clinical entity presenting in majority of patients with nephrotic range proteinuria, microscopic hematuria, impaired renal function and hypertension. The mean age of presentation is reported to be beyond 50 years with 50 patients developing end stage renal disease within a few years. A 28-year-old female presented to us with non-nephrotic range proteinuria, rapidly progressive renal failure (RPRF), microscopic hematuria and mild hypertension. The patient had undergone a renal biopsy at a peripheral center, which was reported as membranoproliferative glomerulonephritis (MPGN) and was being treated with steroids without any benefit. The patient on re-biopsy at our center was diagnosed as FGN on electron microscopy (EM). The patient responded to intravenous pulse methylprednislone and oral cyclophosphamide and is off dialysis for 10 months now. This case highlights the varied clinical and histological presentations of FGN which makes the disease difficult to diagnose more so, in a country like ours where EM is available in only a few centers. An accurate diagnosis aided by high index of clinical suspicion and EM can help in the initiation of appropriate therapy, thereby improving the outcome in this disease which otherwise has a poor prognosis.
