[Progressive familial intrahepatic cholestasis presenting as liver failure].
Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of autosomic-recessive inherited cholestatic disorders that begin in the neonatal period or in the first years of life. There are three types of PFIC defined by different mutations located in the gene responsible for the bile flow through the intrahepatic canalicular transporter system. These disorders usually present in children or young adults and the main clinical manifestations are cholestasis, jaundice and pruritus, and they progress slowly towards liver fibrosis in adult life. PFIC diagnosis is based on clinical suspicion, biochemical findings (that include normal gamma-glutamyl transpeptidase in type 1 and 2, but increased levels in type 3), image techniques that rule-out other disorders, and histological confirmation. Initial treatment consists of symptomatic relief of cholestatic symptoms with choleretic agents (urso-deoxycholic acid). Partial biliary derivation and ileal bypass are intermediate therapeutic options. In case of no response to these treatments, liver transplantation is indicated. We report the case of a neonate with PFIC type 2 presenting as a liver failure.
