    Abstract:
    Primary IgA nephropathy is generally considered an indolent disease, but progression to chronic renal failure is not uncommon, and a rapidly progressive course is observed in some cases, especially when extensive fibrocellular crescents are present. The therapeutic benefit of immunosuppression and plasma exchange remains controversial. We described two patients with primary IgA nephropathy and rapidly progressive renal failure. Both patients showed extensive glomerulosclerosis and crescent formation in their renal biopsies. Corticosteroid and immunosuppressive therapy failed to control the progression of the disease, and plasma exchanges were performed. In both cases, the serum creatinine and creatinine clearance initially improved with plasma exchange and the rapid progression of renal failure was apparently halted. In one patient, the serum creatinine rose when treatment was discontinued and fell again when plasma exchange was recommenced. Nevertheless, the long-term benefit of plasma exchange in crescentic IgA nephropathy was unsatisfactory as the renal function continued to deteriorate in the following 12 months despite an initial stabilization.
