title: [Evolution of delta bilirubin/conjugated bilirubins ratio in serum after live transplantation].
abstract: Serum delta-bilirubin measured in relationship to total bilirubin could be a liver function test in hepatobiliary diseases and even a marker of early rejection after liver transplantation. Delta-bilirubin bound to albumin constitutes with mono and diglucuroconjugates, conjugated bilirubins. We determined the delta-bilirubin/conjugated bilirubins ratio and studied its value in various complications in 16 liver recipients. The results were compared with alanine aminotransferase activity and prothrombin index. Hyperbilirubinemia and a delta-bilirubin/conjugated bilirubins ratio lower than 40% were observed initially. After 15 days, the delta-bilirubin/conjugated bilirubins ratio evolved differently according to the functional state of the graft, which allowed to distinguish three patient groups: in patients with good graft function, the ratio increased regularly to reach 65% or more on the 30th day; in patients with dysfunctional episodes, the ratio was always less than or equal to 40% and did not increase after the 15th day; in other patients, the ratio was lower than 40% and dropped suddenly before death. After liver transplantation, the delta-bilirubin/conjugated bilirubins ratio may be a simple liver function marker. Alone, however, it cannot be used to assess acute rejection.
