Single donor plasma in therapeutic plasma exchange for myasthenia gravis

Abstract

Thirty-seven myasthenic patients were treated with therapeutic plasma exchange (TPE) on different performance schedules using either random or single donor plasma. The two schedules had the same effects in terms of efficacy but single donor replacement gave significantly less side effects in the short and long term. A two exchange procedure on alternate days associated with immunosuppression seems to be an optimal schedule for the treatment of myasthenic patients. A single donor two-exchange on alternate days procedure appears to be safe, useful and can be repeated in patients who need frequent TPE.
