[benign recurrent intrahepatic cholestasis]

Direct hyperbilirubinemia, may result from a variety of pathologies, including structural obstructions with biliary tract occlusions (as in cholelithiasis), infections (e.g. hepatitis) and genetic disorders (Rotor's and Dubin-Johnson's syndrome). One of the less common and probably more frequently underdiagnosed causes is benign recurrent intrahepatic cholestasis (BRIC). First described in 1959, BRIC was further classified into two subgroups which differ in their pathogenesis and clinical manifestation. Both BRIC types originate from impaired function bile salt excretion from hepatocytes to the canaliculi which is mediated by the bile salt export pump (BSEP) which is located on the hepatyocyte membrane, unevenly distributed within the membrane lipid bilayer. In BRIC type-I, a mutation impairs the asymmetrical distribution of BSEP. In BRIC type-II, a mutation occurs directly damaging the BSEP. Apart from cholestasis, clinical manifestations of BRIC type-I include extra-hepatic symptoms such as watery diarrhea, pancreatitis and hearing impairment. Patients with BRIC type-II present mainly with hepatobiliary disease such as colelithiasis. In the past, BRIC was conventionally considered to result in no more than canalicular cholestasis, however several reports have associated BRIC with fibrosis and porto-portal septa formation. Disease course may last between weeks and months, more common in females, at any age, and usually resolves spontaneously, although chronic liver disease has also been described. Treatment modalities range from expectant management, medication (cholestyramine, ursolit) or even surgery (biliary bypass/liver transplantation). This report describes a patient with BRIC type-II and reviews the relevant literature.
