What's happening: an overview of potential adverse reactions associated with apheresis technology.
The current status of potential adverse reactions associated with the use of apheresis technology is reviewed, focussing on three main areas: adverse events related to component collection, progenitor cells collection and therapeutic apheresis. Based on available information it is believed that apheresis technologies are safe and increasingly used in transfusion medicine, including in auto-transfusion and different types of therapy. Occasionally, however, for various donor/patient and operational reasons, mild or moderate adverse reactions do occur. The majority of these reactions are related to vascular access and anticoagulants used, which can be mostly eliminated with calcium/magnesium administration. The reactions associated with therapeutic apheresis are more frequent (6.75%) than the multi-components and stem cell collections. Most of these reactions are generally mild and only 0.89% has been classified as severe. A national registry of donor adverse reactions as well as a planned haemovigilance system may prove helpful in identifying the potential causes which might be associated with either to donor/donation and/or with a particular technology or procedure.
