Therapeutic plasma exchange for fulminant hepatic failure secondary to Wilson's disease

Wilson's disease (WD) is an autosomal‐recessive disorder of impaired copper metabolism resulting in accumulation of copper primarily in the liver but ultimately in many organs and tissues. A small number of patients with WD initially present with fulminant hepatic failure (FHF), hypercupremia, and intravascular hemolysis. The therapeutic goals for these patients include quickly removing the copper and preparing the patient for liver transplantation. Here, we report on a 6‐year‐old male with WD in FHF with anemia, renal insufficiency, and coagulopathy. The patient received a series of therapeutic plasma exchanges (TPE) as adjunctive therapy to remove copper and stabilize his coagulopathy and anemia until a transplant was possible. A total of five single plasma volume (1500 mL) TPE were performed over the course of 11 days with plasma as the replacement fluid. Laboratory results demonstrated temporary improvement after each procedure. Liver transplantation was performed 12 days after beginning TPE and 35 days after admission to the hospital. TPE was a successful adjunctive therapy to bridge this patient with WD to transplantation. J. Clin. Apheresis 27:282–286, 2012. © 2012 Wiley Periodicals, Inc.
