Background and aim: Wilson disease (WD) is an inherited disorder ofhepatic copper excretion leading to toxic accumulation of copper in theliver as well as the brain, cornea, and other organs. The defect is due tomutations of the copper-transporting ATPase ATP7B. Here, we describethe adult cases of hepatic WD diagnosed at the CHUV between 2005and 2010.Methods: Clinical manifestions, results of diagnostic tests, and follow-upof adult patients with hepatic WD were recorded systematically.Results: Seven new adult cases of hepatic WD were diagnosed in ourcenter between 2005 and 2010. Three were women and 4 men, with amedian a ge at d iagnosis o f 24 (range, 1 8-56) years. Three patientspresented with acute liver failure (ALF), three with persistently elevatedliver function tests, and one with a dvanced cirrhosis. None hadneurological manifestations. Only one patient, presenting with ALF, had aKayser-Fleischer corneal ring. Median ceruloplasmin levels at diagnosiswere 0.13 (range, <0.03-0.30) g/l, median 24 h urinary copper excretion6.3 (range, 0.4-62.0) μmol/24 h, and median hepatic copperconcentration 591 (range, 284-1049) μg/g. At least one mutation in theATP7B g ene was i dentified in a ll patients. Allelic frequency of t hecommon H1069Q mutation was 14%. Two patients presenting with ALFand the one with advanced cirrhosis underwent successful l ivertransplantation. One patient with ALF recovered under chelator therapy.D-penicillamine was used as first-line chelator treatment, with a switch totrientine due to adverse effects in 2 out of 4 patients u nder l ong-termtreatment.Conclusions: The clinical presentation of WD and the performance ofdiagnostic tests are variable. A high index of suspicion i n clinicallycompatible situations i s key, with a combination of tests allowing thediagnosis of WD.
