| 2 | Early markers of reperfusion injury after liver transplantation: association with primary dysfunction显示文摘BACKGROUND:In patients with end-stage liver disease,liver transplantation is the only available curative treatment.Although the outcome and quality of life in the patients have improved over the past decades,primary dys-or nonfunction(PDF/PNF)can occur.Early detection of PDF and PNF is crucial and could lead to individual therapies.This study was designed to identify early markers of reperfusion injury and PDF in liver biopsies taken during the first hour after reperfusion.METHODS:Biopsies from donor livers were prospectively taken as a routine during the first hour after reperfusion.Recipient data,transaminases and outcome were routinely monitored.In total,10 biopsy specimens taken from patients with 90-day mortality and PDF,and patients with long-term survival but without PDF were used for DNA microarrays.Markers that were significantly up-or down-regulated in the microarray were verified using quantitative real-time PCR.RESULTS:Age,indications and lab MELD score were similar in both groups.Peak-transaminases during the first week after transplantation were significantly different in the two groups.In total,20 differentially regulated markers that correlated to PDF were identified using microarray analysis and verified with quantitative real-time PCR.CONCLUSIONS:The markers identified in this study could predict PDF at a very early time point and might point to interventions that ameliorate reperfusion injury and thus prevent PDF.Identification of patients and organs at risk might lead to individualized therapies and could ultimately improve outcome. | Helge Bruns Jan Heil Daniel Schultze Mohammed Al Saeedi Peter Schemmer | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，3： | 1 |
