Copper Supplementation in Cirrhosis

Sponsor: University of Washington

Summary

End stage liver disease or cirrhosis is a major cause of mortality in the United States and the world. Other than targeting the underlying cause, such as alcohol cessation and antiviral therapy, very few medical treatments can change the natural history of cirrhosis. Malnutrition is one of the few potentially modifiable factors that have been associated with cirrhosis severity and poor prognosis. The transition metal copper (Cu) is an essential trace metal that must be acquired from diet. Its metabolism is primarily regulated by the liver in its role as a master regulator of nutrients. In 2019, the investigators reported that Cu deficiency defined by below normal serum or liver concentrations occurred in a wide range of liver disorders and was associated with a severe disease phenotype. Improvement in liver function was observed in 2 of the 3 patients who received Cu supplementation. In 2023, the investigators conducted a longitudinal cohort study utilizing clinical, serum and liver explant tissue data from 183 cirrhosis patients. The investigators showed that Cu deficiency was associated with 2-fold higher infection rate and a more than 3-fold increase in the risk of death compared to patients with normal Cu status. These preliminary findings and the well-established importance of Cu in human health prompted the investigators to design the current pilot randomized, placebo-controlled, crossover trial to determine the effect of Cu supplementation on Cu dependent biochemical changes, patient safety and patient reported outcomes in cirrhosis.
