Wilson's disease: varied hepatic presentations.

ABSTRACT

BACKGROUND: Wilson's disease is an inherited disorder of copper metabolism. Previous Indian studies have high-lighted the neurological manifestations of this disorder. Eleven patients with Wilson's disease with different hepatic manifestations are reported. METHODS: Patients referred to the gastroenterology department of a tertiary referral center were investigated for Wilson's disease, based on clinical suspicion, with slit-lamp examination for Kayser-Fleischer rings, serum ceruloplasmin and 24-hour urinary copper estimation. Liver biopsy was done whenever possible. RESULTS: Patients with Wilson's disease presented as acute viral hepatitis (n = 5), fulminant hepatic failure (n = 2), subacute hepatic failure (n = 2) and cryptogenic cirrhosis (n = 2). Therapy with penicillamine/trientene and zinc sulphate was started in 9 patients; 5 showed good response to therapy, one had to be switched to trientene due to penicillamine toxicity, two died, and one was lost to follow-up. CONCLUSION: Wilson's disease has varied hepatic presentations and should be suspected in all patients with unexplained liver disease. Any young adult presenting with acute hepatitis or fulminant hepatic failure who has evidence of underlying chronic liver disease or associated hemolytic anemia should be investigated for Wilson's disease. Therapy with penicillamine or trientene combined with zinc sulphate shows improvement in a majority of patients.
