Due to the non-specific clinical signs, the possible diagnosis of liver disease is frequently not taken into consideration. However, measurement of the plasma or serum concentrations of total bile acids and gamma glutamyl transferase (gamma GT) may provide valuable diagnostic information. The specific diagnosis can be confirmed by ultrasound examination of the liver and histological examination of a liver biopsy specimen. The most frequently documented liver diseases are acute hepatic necrosis, chronic hepatitis caused by pyrrolizidine alkaloids, cholelithiasis, and haemochromatosis. Immediate treatment with antibiotics and polyionic fluids, in association with supportive nutritional care, is usually necessary to maintain the horse until sufficient liver regeneration occurs to provide adequate function. The use of corticosteroids is contraindicated, except for patients with chronic active hepatitis. In some cases, e.g. portosystemic shunts or cholelithiasis, surgical intervention is i...Continue Reading
