What is vacuolar hepatopathy?

What is vacuolar hepatopathy?

Vacuolar hepatopathy (VH) is a commonly diagnosed canine liver syndrome in which hepatocytes become markedly distended with cytosolic glycogen with or without discrete membrane-bound lipid inclusions.

What causes vacuolar hepatopathy?

In fact, any other ongoing disease process (stress, inflammation, infection, cancer, etc) in the liver or in any other organ systems can cause the vacuolar changes to occur.

What is steroid hepatopathy?

Steroid hepatopathy can result from excessive endogenous (hyperadrenocorticism) or administration of exogenous glucocorticoids. It represents one of the most common causes of increased serum hepatic enzyme activities and is the most common diagnosis on hepatic biopsy specimen analysis in dogs in one study.

Do cats get steroid hepatopathy?

The storage form of glucose, glycogen accumulates in liver cells because of steroid medication overuse, an overproduction of steroids in the body, or due to an endocrine disorder (e.g., hyperadrenocorticism, atypical adrenal hyperplasia). Vacuolar hepatopathy is rare in cats.

What is vacuolar degeneration?

Vacuolar degeneration is a pathologic change which can occur in cells of different tissues. The. affected cells are distinguished by the presence of variously sized cytoplasmic vacuoles (up to several µ in diameter), outlined by a single membrane and containing substances of different kinds.

What is cat hepatopathy?

Vacuolar hepatopathy is a reversible condition that occurs when the small cavities in liver cells accumulate too much glycogen (the stored form of glucose) or, in rare cases, lipids (fats or oils).

What is cat Cholangiohepatitis?

Cholangiohepatitis means inflammation of the bile ducts, gall bladder, and surrounding liver tissue. The liver produces bile, which is required for efficient digestion of food. Bile is stored in the gall bladder and passes through the bile ducts into the intestines where it mixes with and digests food, especially fats.

Do steroids affect dogs liver?

Steroid-related liver disease in dogs is the result of the dog being overly sensitive to steroid therapy. Steroids can cause lesions to occur on the liver as a result of negative changes in the liver cells, or hepatocytes.

Can steroids cause liver damage?

Steroid misuse has been associated with liver damage,50,51 tumors,46,52,53 and a rare condition called peliosis hepatis, in which blood-filled cysts form in the liver. The cysts can rupture, causing internal bleeding and even death in rare cases.

How long can a cat with lymphoma live on steroids?

Cats with lymphoma who are not treated with chemotherapy have an average survival time of 4 weeks once the diagnosis has been made. Cats with intestinal lymphoma who are treated with prednisone alone have a life expectancy of 60-90 days.

What causes cell degeneration?

Nonlethal injury to a cell may produce cell degeneration, which is manifested as some abnormality of biochemical function, a recognizable structural change, or a combined biochemical and structural abnormality. Degeneration is reversible but may progress to necrosis if injury persists.
