Therapeutic plasma exchange (TPE) has long been utilized to manage a variety of immune-mediated diseases. The basic principle relies on removal of circulating pathogenic substances from the bloodstream. Methods of plasma separation include centrifuge (cTPE) and membrane (mTPE). Although mTPE has existed for a few decades, recent advances in developing highly permeable filters that are compatible with currently existing dialysis machines has opened a new frontier. Published data in the area of technical and clinical experience with mTPE is lacking. We report our single center experience of 998 inpatient mTPE treatments performed in 237 patients at a large tertiary care academic center. The most common treatment indication was neurologic. We found a very low incidence of patient-reported complications. Filter clotting without the use of anticoagulation occurred in 7.7% of treatments. Laboratory parameters that significantly changed during the course of therapy included serum potassium, platelet count, and partial thromboplastin time. We found that mTPE can be safely and efficiently performed as an alternative to cTPE, and suggest an individualized approach when prescribing this therapy.
