title: Significance of lecithin:cholesterol acyltransferase activity as a prognostic indicator of early allograft function in clinical liver transplantation.
abstract: Rapid and accurate assessment of allograft function in the early postoperative period is critical for successful liver transplantation. This study evaluated the efficacy of lecithin:cholesterol acyltransferase (LCAT) activity as an indicator of early allograft function in human orthotopic liver transplantation (OLTx). During a three-month period between September and November 1987, 9 of 11 adult OLTx recipients whose graft exhibited poor function were studied. Poor graft function was defined as primary nonfunction, need for retransplantation within a week after OLTx, or elevation of the prothrombin time over 20 sec early after OLTx. Plasma LCAT activities (measured pretransplant and at 0, 6, 12, 18, and 24 hr, as well as 3 days, after OLTx) and pretransplant clinical variables were compared with those of 15 control patients whose graft exhibited good function. A significant correlation was found between mean LCAT activities during the first 24-hr after OLTx and early allograft function (P less than 0.05, chi 2 = 5.23). When pretransplant histological findings of the 6 grafts with poor function and the 15 controls together were correlated with the mean LCAT activity within 24 hr following OLTx, a significant association was demonstrated (P less than 0.05). This study suggests that plasma LCAT activity is an effective and practical method for assessing early allograft function following OLTx.
