The Steroid-Sparing Effect of Long-Term Plasmapheresis in Pemphigus: An Update

Abstract: Glucocorticoids and immunosuppressive agents can induce remission in most pemphigus patients, but mortality remains at 5 to 15% as a result of side effects. We reviewed the adjunctive effect of long-term plasmapheresis in 8 pemphigus patients. Four cases had been resistant to conventional therapy. One or 2 large-volume plasmapheresis treatments were given monthly over 5 to 141 months. All patients, were in clinical remission within 2 months. Relapses seldom occurred: the patients stayed in remission 90% (40–94) (median, ranges) of the period. In all cases the daily dose of glucocorticoid was reduced. The prednisone level could be decreased from 38 (15–80) mg/day to 7.5 (2.5–35) mg/day (p = 0.002). The overall level of other immunosuppressive agents remained unchanged, except in 1 patient for whom cyclosporine was introduced. This indicates that long-term plasmapheresis could have a steroid-sparing effect and clinical efficacy in pemphigus.—
