Study Notes

Liver Enzymes

  • Alanine aminotransferase (ALT) is also known as serum pyruvic transaminase (SGPT)
  • ALT is not liver-specific
  • ALT is a leakage enzyme
  • In dogs and cats, ALT is mostly present in hepatocytes
  • ALT levels can increase due to muscle injury
  • Horses and ruminants have little ALT in hepatocytes, therefore elevated levels are usually indicators of muscle damage
  • Aspartate aminotransferase (AST) is a leakage enzyme
  • AST is present in hepatocytes, but also in muscle cells
  • AST levels can increase in muscle injury and liver disease

Ionized Calcium

  • Hypoalbuminemia can cause hypocalcemia
  • Acute renal failure can cause hypocalcemia
  • Hyperparathyroidism can cause hypercalcemia in dogs, commonly due to lymphoma
  • Eclampsia is a cause of hypocalcemia
  • The most common cause of ionized hypercalcemia in dogs is neoplasia
  • The most common primary neoplasm causing hypercalcemia in dogs is lymphoma
  • Hypercalcemia, in which the parathyroid hormone is suppressed, indicates parathyroid-independent hypercalcemia
  • Anal sac apocrine gland adenocarcinoma is another cause of parathyroid-independent hypercalcemia in dogs
  • Other causes of hypercalcemia include hypovitaminosis D, pancreatitis, ethylene glycol poisoning and soft tissue trauma
  • Phosphate binders should not be used as they don't reliably predict ionized calcium concentration
  • Acidosis and alkalosis can affect ionized calcium concentration
  • Acidosis increases ionized calcium concentrations
  • Alkalosis decrease ionized calcium concentrations
  • Parathyroid hormone is usually low or low-normal in cases of primary hypoparathyroidism
  • Hypermagnesemia can also be seen in cases of primary hypoparathyroidism
  • Hypomagnesemia can also cause hypocalcemia
  • Hypocalcemia can also be caused by dilution with calcium-free IV fluids
