Long-Term Outlook for Alagille Syndrome


Off-label pharmacologic agents are often used to manage symptoms of Alagille syndrome with limited success. As a result, surgical biliary diversion and liver transplant represented the only effective treatment option for most liver symptoms of Alagille syndrome, but they present several issues. In the case of a surgical biliary diversion, individuals typically require a stoma, which many view as stigmatizing. In the case of liver transplants, issues include lifelong immunosuppressive therapy or surgical complications. These are practical limitations to treatment.1

Recently, a class of medicines called IBAT inhibitors have been approved by the FDA to treat the itch in certain liver disorders.1-3

Treatment Goals

For patients with Alagille syndrome, there is a need for more noninvasive treatment options.1,4

The goals of these treatments should be to1,4:

Reducethe accumulation of bile acids in the liver and bloodstream

Relievecholestatic pruritus


Limitthe progression of liver disease

Improvelong-term prognosis


There is promising research underway for additional treatment options. These may play a crucial role in reducing the symptoms of Alagille syndrome.1
