Feline hepatic lipidosis

Area of Science:

• Veterinary Medicine
• Hepatology
• Feline Internal Medicine

Background:

• Hepatic lipidosis (fatty liver disease) in cats results from an imbalance between lipid mobilization to the liver and lipid removal via very-low-density lipoprotein (VLDL) formation or oxidation.
• This condition is frequently linked to overt liver dysfunction and is commonly triggered by starvation in adult cats.
• Impaired removal of hepatic lipids can stem from protein malnutrition, carnitine deficiency, or oxidative damage to hepatic organelles like peroxisomes.

Purpose of the Study:

• To elucidate the pathophysiology of hepatic lipidosis in cats.
• To outline diagnostic criteria for feline hepatic lipidosis.
• To establish the efficacy of aggressive nutritional support as a primary treatment modality.

Main Methods:

• Diagnosis involves a comprehensive evaluation of laboratory results and diagnostic imaging.
• Liver biopsy is a key diagnostic procedure for confirming feline hepatic lipidosis.
• Treatment focuses on aggressive nutritional support, primarily through tube feeding.

Main Results:

• Clinical signs of hepatic lipidosis in cats include weight loss, depression, vomiting, and icterus.
• Aggressive tube feeding as a treatment strategy demonstrates significant efficacy.
• Survival rates following aggressive tube feeding range from 60% to 80%.

Conclusions:

• Hepatic lipidosis is a serious condition in cats, often precipitated by starvation and characterized by impaired lipid metabolism.
• A combination of diagnostic data and liver biopsy is crucial for accurate diagnosis.
• Prompt and aggressive nutritional intervention, particularly tube feeding, is the recommended treatment, leading to favorable survival outcomes.
