Treatment of non anti-GBM-antibody mediated, rapidly progressive glomerulonephritis by plasmapheresis and immunosuppression.
A retrospective study was conducted to evaluate the efficacy of plasmapheresis in combination with different immunosuppressive drugs ("pulse" therapy, azathioprine or cyclophosphamide together with steroids) in nine patients presenting with rapidly progressive glomerulonephritis (RPGN) not mediated by antibody to glomerular basement membrane. Six of these patients had to be initially dialysed. All patients underwent renal biopsy, which revealed that seven patients had a minimum of 80% crescents and five had interstitial fibrosis. Recovery of renal function was observed in seven patients (78%). All patients without interstitial fibrosis were recompensated for at least 14 months after the acute onset of RPGN. Those who presented with interstitial fibrosis declined to endstage renal failure after 13 months requiring chronic hemodialysis treatment or cadaveric kidney transplantation. On the basis of these findings interstitial fibrosis seems to be a limiting factor for the prognosis of non-anti-GBM-antibody mediated RPGN.
