[Liver transplantation in Wilson's disease patients, 1996-2017]

Introduction: Wilson's disease is a lethal-without-treatment inherited disorder of copper metabolism. Despite the increased focus on the diagnosis and treatment, liver transplantation is needed in a number of cases even nowadays. Aim: To collect and analyze the data of the Hungarian Wilson's disease patients who underwent liver transplantation. Method: Data of 24 Wilson's disease patients who underwent liver transplantation at the Semmelweis University have been analyzed retrospectively. The diagnosis of Wilson's disease was based on the international score system. The diagnosis of acute liver failure corresponded to the King's College criteria. All liver transplantations had been performed at the Department of Transplantation and Surgery of Semmelweis University, in 1996 for the first time. Results: The mean age was 26 years, F/M = 13/11. Twelve patients needed urgent liver transplantation for acute liver failure, and 12 underwent transplantation for decompensated liver cirrhosis. One patient had been retransplanted because of chronic rejection. Three patients with acute on chronic liver failure were transplanted via the Eurotransplant program. The mean time on the waiting list was 3 vs 320 days in acute liver failure and chronic liver disease groups, respectively. The overall 5-year survival was 66%, but it was 80% after 2002 indicating both the learning curve effect and the improvement of vigilance in Hungary. Despite difficulties of the diagnostic process, Wilson's disease was identified in 21/24 patients prior to the transplantation. Conclusion: Liver transplantation is needed in a number of cases of Wilson's disease. The ideal indication and timing of transplantation may improve the survival of the patients.
