Recent clinical features of Wilson's disease with hepatic presentation

Background. We carried out this study to evaluate recent clinical features of Wilson's disease (WD) with hepatic presentation, especially in terms of age, degree of liver injury, and association with hepatocellular carcinoma (HCC). Methods. Sixteen patients with hepatic manifestations were diagnosed with WD in the period 1976-2003. We divided this period into two periods, "past" and "recent". The diagnosis was based on the presence of Kayser-Fleisher rings, low serum copper levels, low serum ceruloplasmin levels, increased urinary copper concentrations before or after D-penicillamine challenge, and increased hepatic copper concentrations. This retrospective study was done at Ehime University Hospital. Results. Four patients, including a pair of siblings, had a family history of WD. Four patients had parental consanguinity. There were 6 patients aged over 40 years in the recent period, whereas no patients in the past period were over 40. Four patients had neurological manifestations. Ten patients had liver cirrhosis and 5 had chronic hepatitis. Two had fatty liver without obesity. All patients in the past period had liver cirrhosis. Three patients with liver cirrhosis were found to have HCC during the follow up. All patients were treated with either D-penicillamine or trientine chloride, or both. However, four patients had to discontinue these agents due to the side effects. Conclusions. Recently, the number of patients diagnosed with WD has been increasing, not only in terms of those with classical-type WD but also in terms of elderly patients or patients with non-cirrhotic liver injury such as fatty liver and chronic hepatitis. The various clinical features of WD should be recognized and particular attention should focus on HCC as a complication.
