Cholangiofibrosis in Hamsters

Cholangiofibrosis is associated with the inflammation and scarring of the liver and bile ducts. Essentially, it is related to two separate conditions: hepatitis and cholangitis. Inflammation of the liver (or hepatitis) can cause fibrous (scar) tissue to form if left untreated for more than three months. The fibrous tissue constricts the blood vessels in the liver, affecting its blood flow. Cholangitis, meanwhile, is defined as the inflammation of the bile ducts. If left untreated, it can also cause fibrous tissue to form which reduces or stops the flow of bile.

Cholangiofibrosis is usually seen in older hamsters, especially females. Unfortunately, there is no effective treatment for cholangiofibrosis, making the general outcome of affected hamsters poor.

Symptoms

• Loss of appetite (anorexia)
• Depression
• Edema and fluid buildup in the abdomen
• Yellowing of the skin and/or eyes (jaundice)
• Nervous system symptoms (in severe cases)

Causes

Though the cause of cholangiofibrosis is unknown, various reasons like liver disease, infectious agents, and toxic chemicals have all been suspected. Older hamsters, particularly females, are said to be prone to develop cholangiofibrosis.

Diagnosis

Your veterinarian will suspect some liver disorder by observing the clinical symptoms. However, cholangiofibrosis can only be confirmed with the assistance of X-rays and scans. Blood test results can also suggest a liver disease if an abnormal increase in enzymes is discovered.
