Hepatic copper content, urinary copper excretion, and serum ceruloplasmin in liver disease.
Increased liver copper concentration and raised serum ceruloplasmin were demonstrated in primary biliary cirrhosis and disorders of the biliary tract, and occasionally in chronic active hepatitis and cirrhosis of the liver. Eight of 13 patients with primary biliary cirrhosis had liver copper content as high as seen in patients with hepatolenticular degeneration (is greater than 250 mjg/g dry weight). Normal liver content was found in patients with acute hepatitis, steatosis of the liver, hepatic amuloidosis, haemochromatosis, and Gilbert's syndrome. The urinary copper excretion was increased (is greater than 75 mjg/24 h) in half the patients with primary biliary cirrhosis and occasionally in the other patient groups. Serum ceruloplasmin was raised in more than half of all patients, and none had levels below the reference range. Raised heaptic copper content did not always coincide with enhanced urinary copper excretion, but was significantly correlated with this parameter and also with ceruloplasmin, alkaline phosphatases, and vitamin-K-dependent clotting factors, but not with ALAT. Combination of laboratory data, as found in typical cases of hepatolenticular degeneration, was not observed in this study, including 66 patients.
