Abstract
A prospective clinical study evaluated the effects of combined chemotherapy, steroids, and plasmapheresis on 5 patients with mixed cryoglobulinemia with renal or neurologic and vasculitic manifestations. Treatment included prednisone (1 mg/kg/day), chlorambucil (white blood cell count at > 3,000/mm3), and plasmapheresis (1 to 3 liters/week). There was healing of cutaneous uleers (3/3), improvement in renal function (4/4), and diminution of purpura (2/2), but little improvement in peripheral neuropathy. Complications included leukopenia, perineal ulcers, and osteomyelitis.
