Liver transplantation for Wilson's disease

Area of Science:

• Hepatology
• Transplantation Surgery
• Metabolic Diseases

Background:

• Wilson's disease is a rare genetic disorder causing copper accumulation in the liver and other organs.
• Orthotopic liver transplantation (OLT) is increasingly used for managing severe metabolic liver diseases.
• This study reports on the University of Pittsburgh's experience with OLT for Wilson's disease.

Purpose of the Study:

• To evaluate the efficacy and outcomes of orthotopic liver transplantation in patients with Wilson's disease.
• To assess survival rates and complications associated with OLT in this patient population.
• To determine the suitability of OLT for different clinical presentations of Wilson's disease.

Main Methods:

• A retrospective analysis of 51 OLT procedures performed on 39 Wilson's disease patients (16 pediatric, 23 adult) between 1981 and 1991.
• Patients were categorized based on presentation: fulminant hepatic failure (n=22) or chronic advanced liver disease with/without neurologic dysfunction (n=17).

Main Results:

• The primary graft survival rate was 73%, and patient survival was 79.4% at the end of the study period.
• No mortality occurred beyond 3 weeks post-OLT.
• Survival rates were higher for patients with chronic advanced liver disease (90%) compared to fulminant hepatic failure (73%), though not statistically significant.

Conclusions:

• OLT is the treatment of choice for Wilson's disease presenting with fulminant hepatic failure.
• OLT should be considered for patients with advanced chronic liver disease when other therapies fail.
• OLT partially corrects the metabolic defect, converting copper kinetics to a heterozygote state, achieving a phenotypic cure.
