Hepatic copper accumulation in primary biliary cirrhosis

Yale J Biol Med. 1979 Jan-Feb;52(1):83-8.

Abstract

Hepatic copper accumulation is a regular feature of primary biliary cirrhosis (PBC). The levels are directly related to the clinical stage of the disease. Since the copper values in PBC are comparable to Wilson's disease, there is the potential for copper toxicity, although this is speculative since the two diseases differ in the binding, distribution, and intracellular localization of the copper. The involvement of copper toxicity in the progression of PBC is supported by the observation that the highest values occur in association with the hepatic failure that occurs in the advanced stage.Corticosteroid therapy appears to decrease hepatic copper levels in PBC. Although this therapy does not invariably lower the hepatic Cu content in patients with PBC, it does so in many individuals. Therapeutic trials with d-penicillamine are in progress. When results are available they will guide us in the management of individual patients with PBC. In the meantime, dietary copper should be restricted as is done in management of Wilson's disease.
