Hepatic Disorders
As an enzyme cofactor, copper supports crucial functions in the body, including red blood cell formation, iron metabolism, connective tissue formation, central nervous system development and function, melanin pigment formation, and immune function. Dietary copper is supplied in the diet, stored in the liver, and delivered to other tissues as needed.1
Due to defects in copper excretion into the bile (the primary route of elimination from the body), excessive levels of copper can accumulate in the liver, which causes oxidative injury and inflammation. The disease is initially characterized by a subclinical phase. However, with continued copper accumulation, hepatitis and eventually liver cirrhosis ensue. Excessive copper accumulation is the leading toxic cause of chronic hepatitis.2
Although it may be seen in any breed, copper-associated hepatitis has been linked to a genetic defect identified in Bedlington Terriers, Labrador Retrievers, and Doberman Pinschers.2-5
Diet plays a key role in the management of copper-associated hepatitis.
“Your pet’s liver condition is caused by high copper levels in [his/her] liver. In addition to medical management, feeding [pet’s name] a low-copper diet is a key part of managing the condition.”
