BACKGROUND/AIMS: Wilson's disease (WD) is a rare inborn disease related to copper storage, leading to liver cirrhosis and neuropsychological deterioration. The aim of this study was to determine the clinical presentation and long-term outcome, and to examine the progression of hepatic histopathology in serial liver biopsies from WD patients. MATERIALS AND METHODS: We carried out a retrospective analysis of 60 patients with WD treated with zinc and/or penicillamine. Demographic, clinical, and laboratory data were gathered and 40 patients underwent an initial biopsy and at least one repeat biopsy. Patients were divided into two groups: progressors (patients who presented worsening of at least one unit of fibrosis) and nonprogressors (patients who presented stable or improved fibrosis scores). RESULTS: A total of 33/40 (83%) patients (nonprogressors) showed stable hepatic histology or improvement. Seven of 40 (17%) patients (progressors) showed worsening of fibrosis. There was no significant correlation between the histological findings and clinical parameters or initial presentation. CONCLUSION: In our study cohort, liver disease was stable or improving in most of the patients, and development of progressive hepatic symptoms while under treatment was a rare event. The development of new symptoms while under treatment or progression of pre-existing symptoms was more often recorded for neurological than for hepatic symptoms.
