Abstract
Wilson's disease is an autosomal recessive disorder of copper accumulation in various organs, with most common clinical manifestations such as hepatic, neurological, and renal dysfunctions. Serum copper and ceruloplasmin in Wilson's disease were significantly lower as compared to normals, controls, and relatives of Wilson's disease patients, whereas marked hypercupriuria (145+/-7 microg/24 h) was observed in Wilson's children only. A good correlation (r=0.92) was found between non-ceruloplasmin-bound copper and 24-h urinary copper excretion in Wilson's disease patients. Further, copper studies among the different phenotypes of Wilson's disease revealed substantially low serum ceruloplasmin and a marked hypercupriuria in Wilson's disease children associated with renal tubular acidosis as compared to the patients with either hepatological or neurological manifestations. Serum ceruloplasmin levels in 14 patients of Wilson's disease were between 14 and 20 mg/dL. These patients of Wilson's disease were confirmed by measuring liver biopsy copper, which was about nine times higher than normal hepatic copper content. During the family screening by copper studies, four asymptomatic siblings were diagnosed for Wilson's disease. These subjects were then started on D-penicillamine therapy because presymptomatic treatment prevents progression of the disease complications.
