ABSTRACT
Seven symptomatic patients with Wilson's disease have so far been diagnosed at King Khalid University Hospital (KKUH), Riyadh, over the last six years. On family screening, another three asymptomatic patients were found to be affected. Five of the symptomatic patients had clinical features of liver disease on initial presentation and was preceded by renal dysfunction in another patient. The remaining patient presented with neurological features. Six patients had Kayser-Fleisher ring. Abnormal liver function tests were found in half of the patients. Ceruloplasmin was reduced in 7 of 10 patients. Serum copper and urinary copper estimations were most useful diagnostic laboratory tests. Morphological alteration was found in all 9 patients who had a percutaneous liver biopsy. All patients were treated initially with D-penicillamine and clinical response was noted in seven, of whom one developed neurological manifestations while receiving the treatment. D-penicillamine was replaced by zinc sulfate in 3 patients who developed thrombocytopenia. The data suggest that Wilson's disease may not be rare in Saudi Arabia. For early detection and prompt treatment, the disease should be suspected under appropriate clinical circumstances especially in young patients with liver diseases. Close relatives of such index patients should be routinely screened.
