Background:
Early allograft dysfunction (EAD) had been established as a useful tool to asses graft and patient survival after liver transplant. We wanted to evaluate effect of EAD components on early graft survival.
Methods:
This retrospective study included 264 patients with EAD after liver transplant in the period between 2015 and 2019. The patients with retransplants were excluded from analyses. The EAD was determined with Olthoff criteria. The logistic regression model was used for analyses. The 90-day graft survival was set as a primary outcome measure.
Results:
The main indications for transplant in the analyzed group were hepatitis C virus infection (53 patients, 20.1%), hepatitis B infection (22, 8.3%), primary sclerosing cholangitis (28, 10.1%), and alcoholic liver disease (62, 23.5%), with a median model for end-stage liver disease score of 13.5 points. The 90-day graft loss occurred in 51 patients (19.3%). Each of the components used in EAD diagnosis was found to be correlated with 90-day graft loss. The bilirubin concentration on day 7 (odds ratio [OR], 3.1; 95% CI, 1.4-6.7; P < .001), international normalized ratio on day 7 (OR, 179; 95% CI, 39-815; P < .001), and the natural logarithm of alanine aminotransferase (OR, 3.1; 95% CI, 1.6-6.4) and aspartate aminotransferase (OR, 1.4; 95% CI, 0.4-4.9) predicted 90-day graft loss.
Conclusions:
In patients with EAD, international normalized ratio ≥ 1.6 on day 7 was the strongest predictor of early graft-loss among all EAD components.
