Since 1983, 28 patients with a rapidly progressive glomerulonephritis were treated with apheresis. Seventeen patients had a primary glomerulonephritis, while 11 had a secondary form. Pathological pattern showed crescentic glomerulonephritis in all cases but one. In 23 cases of 28, renal survival was compromised within a few months. Apheresis were performed with the filtration technique, using a single needle device and central venous catheter. Plasmafilters were reused since 1984. In 1987, cascade filtration was introduced. The procedure was under permanent medical control. Mean reuse rate was 6 time. Renal actuarial survival curve showed a 60%, 42% and 21% survival rate at respectively 1, 2 and 5 years. Five deaths were noted. No death occurred during the apheresis procedure. The mean cost of filters and blood lines was 490 French francs (FF) per session; the mean cost of an haemodialysis session was 1900 FF. When the real survival time was compared to the expected renal failure without apheresis (assuming a linear progression of the disease), patients with a positive response to apheresis saved 488 dialysis months. The amount saved was 12 MFF. The additive cost of inefficient apheresis was 0.06 MFF. These data have to be considered on a 0.5 M inhabitants population basis during a 10 year survey.
