Chronic Hepatitis in Standard Poodles
Chronic hepatitis is a disease characterized by inflammation of the liver that is progressive and often fatal. The cause of chronic hepatitis is usually unknown with the exception of a breed-related inherited copper storage disease observed in Bedlington Terriers. This disease is treatable using specific copper chelators, and through genetic counseling, the disease has essentially been eliminated from the breed. Several other breeds are also thought to have copper-associated hepatitis, but the exact mechanism of disease and mode of transmission remain to be determined. There are also other breeds predisposed to non-copper-associated chronic hepatitis. These are considered to have idiopathic chronic hepatitis. Proposed etiologies include: infectious, toxic, drug-induced, autoimmune, or breed-related metabolic errors. The treatment for most cases of chronic hepatitis is supportive, and the disease is currently unpreventable. Chronic hepatitis is usually not diagnosed until dogs are middle-aged or older, and most breeding dogs are younger than the age at which signs of hepatitis appear; thus transmission via selective breeding is generally unpreventable. Standard Poodles appear predisposed to develop chronic hepatitis, but there has not been a comprehensive documentation of the incidence or description of the disease. Currently the cause, clinical manifestations, genetics involved in the transmission, and the appropriate therapy needed for management of hepatitis in Standard Poodles are unknown. Our goal is to first describe chronic hepatitis in the Standard Poodle using the clinical, laboratory and histopathology findings. With this information we plan to apply for additional funding for a comprehensive project to identify the cause of chronic hepatitis in Standard Poodles, as well as to determine genetic transmission and therapy.
