Chronic active hepatitis in Doberman pinschers.

Eleven Doberman Pinschers were affected with a disease that had clinical signs, serum biochemical abnormalities, and histologic features of chronic active hepatitis. Intrahepatic cholestasis and accumulations excess hepatic copper were prominent features. Most of the dogs deteriorated within weeks to months, and 6 died within 9 months after the 1st signs of disease were noticed.

Interpretation of canine liver biopsy. A clinician's perspective.

Proper evaluation of hepatic biopsies is essential for the proper management of dogs with liver disease. The clinician must have some basic knowledge of hepatic anatomy and histopathologic nomenclature in order to establish an accurate prognosis and therapeutic plan.

Feline hepatic disease.

Species differences in anatomy, physiology, and biochemistry lead to many dissimilarities between the canine and feline liver. Major differences exist in the interpretation of liver function tests, the significance of biochemical jaundice, the consequences of anorexia, and the efficiency of hepatic metabolic systems. Biochemical alterations in total bilirubin, ALT, and SAP may indicate the presence of disease in the feline liver. It is, however, impossible to make accurate diagnoses without liver biopsy. A liver biopsy can provide a diagnosis and prognosis and can guide the therapeutic plan. The feline hepatic diseases most frequently seen in our hospital are hepatic lipidosis, cholangiohepatitis complex, toxic hepatopathy, and hepatic neoplasia. Less common diseases of the feline liver include extrahepatic biliary obstruction, portacaval vascular anomalies, hepatic parasites, hepatic cysts, and diaphragmatic hernia. Systemic diseases that can effect the liver of cats are feline infectious peritonitis, multicentric lymphosarcoma, myeloproliferative diseases, hemolytic anemia, infectious panleukopenia, and systemic fungal infections.
