Also known as: Foie gras
La lipidose hépatique est l'accumulation excessive de graisse dans les cellules hépatiques, altérant la fonction du foie. Elle se développe lorsqu'une période de baisse de la prise alimentaire déclenche une mobilisation des graisses corporelles qui submerge le foie. Elle est plus fréquente et plus sévère chez le chat, mais peut survenir chez le chien, souvent en association avec une autre maladie. Avec un soutien nutritionnel précoce et énergique, le pronostic peut être bon.
Hepatic lipidosis is the build-up of fat inside liver cells to the point that the liver cannot work properly. It classically follows a period of anorexia, when the body mobilizes fat faster than the liver can process it. It is far more common in cats but is occasionally seen in dogs.
Any cause of decreased food intake can trigger it, often a concurrent illness such as pancreatitis, infection, or another organ disease. Obesity increases the available fat and the risk.
Signs include marked appetite loss, weight loss, jaundice, vomiting, lethargy, weakness, and sometimes drooling or neurologic signs in severe cases.
Elevated liver values and jaundice with a history of not eating prompt ultrasound and often a liver aspirate or biopsy showing fat-laden cells, while searching for the underlying trigger.
The cornerstone is early, adequate nutritional support, frequently via a feeding tube, plus fluids, anti-nausea drugs, and treatment of the underlying disease.
Preventing obesity and ensuring any sick or stressed animal continues to eat, with prompt intervention for anorexia, are the best preventives.
