Veterinary Medicine: Common Clinical Problems

Disorders and Conditions

• Arteriovenous fistulas are categorized under vascular disorders.
• Condition characterized by mild hepatic injury is known as mild portal inflammation with no hepatocyte death.

Liver Disease Activity

• Activity of liver disease is determined by the presence of inflammation and necrosis in the liver.
• Inflammation of bile ducts and surrounding tissues is referred to as cholangitis.
• Accumulation of excessive glycogen in the liver is known as glycogenosis.
• Liver's exposure to inflammatory cytokines and endotoxin from the gastrointestinal viscera is termed endotoxemia.

Clinical Signs and Diagnosis

• Atypical clinical sign NOT commonly observed in dogs with chronic hepatitis is polydipsia (excessive thirst).
• Azathioprine is classified as an immune-modulating therapy for chronic hepatitis treatment in dogs.
• Breeds NOT mentioned with copper concentrations similar to Dalmatians include Beagle.

Copper Metabolism

• Primary recipient of copper in canine metabolism is the liver.
• Diagnostic criteria for chronic hepatitis in dogs includes hepatic copper quantification exceeding 400 μg/g dry weight.

Disease Severity and Management

• In dogs with chronic hepatitis, more severe and progressive disease may be characterized by elevated liver enzymes.
• Primary challenge in managing copper-restricted diets lies in ensuring adequate nutrition while minimizing copper intake.
• Premature dietary protein restriction can lead to protein-energy malnutrition.

Prognosis and Dietary Management

• Negative prognostic indicator in patients with liver disease includes rapid progression of clinical signs.
• Average survival time for patients with cirrhosis or lobular dissecting hepatitis is approximately 1 year.
• Poor prognosis in liver disease patients is associated with factors like advanced age and concurrent illnesses.
• Dietary protein restriction should be implemented only after clinical signs of liver failure develop.
