Partial Plasma Exchange is an advanced version of TPE (Therapeutic Plasma Exchange) which our medical team uses in combination with H.E.L.P. Apheresis due to the significantly better risk-benefit profile in chronic illness. This therapy is not used for patients suffering from fatigue/PEM. For some of those patients it is used later on in the therapy course (when the fatigue/PEM has subsided already).
Note: Therapeutic Plasma Exchange (TPE) with albumin (artificial plasma) can have severe side effects for people with chronic illness. This is why we developed a much 'softer' version (Partial Plasma Exchange) where only a small fraction of the plasma is exchanged at the end of a H.E.L.P. Apheresis therapy with saline (NaCl. 0,9%). In other words - it increases the efficiency of the original H.E.L.P. Apheresis by removing an even higher percentage of autoantibodies and pathogens, but as it also removes a small fraction of the plasma, which is why it can not be used for fatigue/PEM patients.
Side effects if removal/administration ratio and timing are handled wrong include swollen ankles and facial oedemas.
