Core Tip

Core tip: High volume plasmapheresis has been shown to improve survival in non-transplanted patients with acute liver failure. However, there has not been, to date, a review article that summarizes the different plasmapheresis regimens and its effect on mortality and improvement of liver biochemistry. This review article serves as a summary and appraisal of available literature on plasma exchange in liver failure taking into account the volume of plasma exchange, duration of plasmapheresis, and etiology of liver failure in conjunction with the study outcomes of interest and highlights potential areas which might be essential to include in future good quality randomized controlled trials.
