What is the difference between plasmapheresis and plasma exchange




















Shehata et al performed a systematic review to identify all randomized controlled trials involving apheresis published between and Because the diseases treated with apheresis are rare, for many diseases, the published evidence may consist solely of case reports or small case series. Whereas controlled trials may exist for more common diseases, randomized trials are uncommon. To provide practical, evidence-based guidance to the apheresis practitioner and to encourage critical science in the field of apheresis medicine, ASFA has published guidelines on the use of therapeutic apheresis in clinical practice.

The latest guidelines, published in , are the 5th edition. To create these guidelines, a group of apheresis experts reviews the previous guidelines and suggestions from the ASFA membership or interested parties to determine which diseases and disorders should be evaluated. The members are then each assigned specific diseases. They are asked to review the English language literature related to the use of therapeutic apheresis in their assigned disorders.

This is then reviewed by the entire committee, with additional input creating a third draft. After this, based upon consensus of the committee, each disorder is assigned an ASFA category and recommendation grade. The categories are defined in Table 5. The recommendation grade is based upon the Grading of Recommendations Assessment, Development and Evaluation GRADE system 27 and provides the strength of recommendation and an indication of the quality of evidence supporting the use of the apheresis treatment.

A grade 1 recommendation represents a strong recommendation either to perform or not perform the apheresis treatment, depending upon the ASFA category. A grade 2 recommendation represents a weak recommendation. This is further modified by an A, B, or C indicating high-quality evidence, moderate-quality evidence, or low-quality evidence, respectively. The ASFA guidelines are revised and published every 3 years, with the next publication scheduled to occur in June of ASFA categories 2.

The ASFA guidelines have been recognized worldwide and have been translated into Spanish and Russian, with plans for translation into simplified Chinese. Several international apheresis societies have endorsed or adopted these guidelines. Finally, many third-party payers are basing their coverage decisions upon the information included in the guidelines. Plasma exchange is a therapeutic procedure used to treat a wide variety of diseases through the bulk removal of plasma.

Whereas the mechanism of action has been thought to be the removal of pathologic Igs, there is evidence suggesting an immunomodulatory effect. The procedure is safe, with the majority of reactions and complications being mild, easily treated, and of limited duration. Unfortunately, the published evidence supporting the use of plasma exchange is of limited quality. To assist the practitioner in the determining the appropriate use of plasma exchange and other apheresis treatments, and to promote additional studies of the role of apheresis, the ASFA has created evidence-based guidelines that have been accepted internationally as indications for the use of apheresis in clinical medicine.
