Background: PEXIVAS was the largest clinical trial conducted on severe AAV patients and failed to demonstrate the contribution of PLEX on the prognosis of severe AAV. No attempt for desensitization was made for such patients. CPFA is performed according to the clinical situation, from 1 to 5 daily sessions. With the introduction of venous mapping methods prior to the placement of a central venous catheter RaPeVA, RaCeVA,. After capturing donor HLA, the beads were transferred to a filter plate and washed in conjunction with the vacuum manifold.

Cost of treatment with plasma exchange for each patient was compared with other available modalities. The buildup of disease contributing plasma components will continue after plasmapheresis if the underlying disease or disorder is not identified and treated, resulting in repeated plasmapheresis treatment being required. Further studies are required to determine if greater reductions in autoantibody concentration may be therapeutic; this could be theoretically achieved with more aggressive plasmapheresis regimens, at <3 day intervals, with five or more exchanges over a period of 7–14 days 7. In addition, we achieved sufficient clearing of ANCA and pro inflammatory cytokines Supplementary data, Figure 1A. The result of plasma exchange in terms of improvement in clinical condition of patient was Excellent i. The analysis performed in this study was limited to the variables captured in the donation registry, and as such, the inability to account for the effect of factors such as donor weight, ethnicity, first time donation status, history of VVRs, waiting time, time since last meal and pre donation psychometric variables is potentially a limitation.

Plasmaperfusion is a 2 steps process during which plasma is first extracted from the blood and then circulated through a sorbent designed to retain some specific substances such as antibodies, Lpa or LDL cholesterol. Thirty seven grams of plasma proteins were removed during each immunoadsorption, which required no replacement, compared with 175 grams during plasma exchange, which requires replacement with albumin.
