Low-phospholipid-associated cholelithiasis syndrome (LPAC) is associated with ABCB4 genetic mutation. ABCB4 encodes MDR3 protein, involved in biliary phosphatidylcholine excretion. Higher prevalence in women, biliary symptoms in young adults and ursodesoxycholic acid (UDCA) response are the main features. We report the case of a 48-year-old man with hepatitis C, genotype 1b, fibrosis F3, null responder to Peg-IFNα2b/ribavirin and nephritic colic. In 2011 he developed jaundice, pruritus and epigastric pain. He showed increased serum levels of AST, ALT, GGT, bilirubin and alpha-fetoprotein, and viral load (14,600,000IU/mL). Pancreatic-CT, endoscopic ultrasonography and echo-Doppler showed noncirrhotic chronic liver disease. The episode resolved spontaneously and one year later he suffered a similar episode. UDCA was started with excellent response. An immunohistochemistry study and sequencing of ABCB4 did not find alteration. MLPA® technique detected heterozygous deletion of the full exon 4 confirming LPAC syndrome diagnosis. © 2014 Arán Ediciones, S. L.
