Serum and urinary copper in acute hepatic encephalopathy.

ABSTRACT

Serum and 24 hours' urinary copper levels were studied in 71 patients with acute viral hepatitis including 35 with encephalopathy. Thirty age and sex matched healthy controls were also studied. Copper estimation was done by atomic absorption spectrophotometry. Serum and 24 hours' urinary copper levels (164.85 +/- 29.31 micrograms/dl and 123.54 +/- 7.87 micrograms/24 h respectively) were significantly (P less than 0.001) increased in acute viral hepatitis patients. There was no significant difference in levels between patients with and without encephalopathy.
