PFIC is a rare and inherited condition as a result of a gene mutation. Bile is unable to drain from the liver, even though the large bile ducts are open, causing bile to build up in liver cells.
Causes
PFIC is a group of inherited diseases caused by altered genes (mutations).
A buildup of bile acids in the liver causes damage to the liver cells. It is not necessarily bile and many of these patients have normal bilirubin
Signs and Symptoms
Itching
Poor weight gain
Jaundice
Bleeding caused by vitamin K deficiency
Poor bone growth caused by vitamin D deficiency
Enlargement of the liver and spleen
Fatigue
Poor feeding, throwing up, diarrhea
Problems that may be result of PFIC:
Failure to grow
Vitamin deficiencies
Cirrhosis
Liver cancer
Gallstones
Diagnosis
Blood tests
Ultrasound, CT scan or MRI
Liver biopsy
Genetic testing
Treatment
Treatment mainly focuses on minimizing growth failure and decreasing discomfort.
Supplemental and fat-soluble vitamins are often recommended.
Odevixibat is approved for itching in PFIC
Treatments target symptomatic relief with the use of medications that can increase bile flow. A liver transplant may be needed.
