摘要
Progressive familial cholestasis type 2 is caused by a genetically determined absence or reduction in the activity of the bile salt export pump (BSEP). Reduction or absence of BSEP activity causes a failure of bile salt excretion, leading to accumulation of bile salts in hepatocytes and subsequent hepatic damage. Clinically, patients are jaundiced, suffer from severe intractable pruritus, and evidence progressive liver dysfunction. A low level of serum gamma-glutamyl transpeptidase, when associated with the described signs and symptoms, is often an early identifier of this condition. Treatment options to date include liver transplantation and the use of biliary diversion. We report a multidrug regimen of 4-phenylbutyrate, oxcarbazepine, and maralixibat (an experimental drug owned by Shire Pharmaceuticals, Dublin, Republic of Ireland) that completely controlled symptoms in 2 siblings with partial loss of BSEP activity.
