ABSTRACT
This study aimed to investigate risk factors for early allograft dysfunction (EAD) and outcomes after liver transplantation (LT), focusing on peri-transplant lactate clearance. We reviewed patients who underwent deceased donor LTs between 2011 and 2014. Lactate levels were checked at reperfusion and at the time of intensive care unit admission. Early lactate clearance was defined as reduction rate of lactate between the times of reperfusion and immediately after LT. Patients were categorized into the normal and delayed clearance groups. We used propensity score matching (PSM) between these two groups to estimate an impact of lactate clearance on incidence of EAD and graft survival. A total of 256 recipients were eligible for this study. Cut-off value of lactate clearance to predict occurrence of EAD was determined at 0.2 mmol/L/h. After PSM, 120 patients in the normal clearance and 36 patients in the delayed clearance group were matched. Delayed lactate clearance was considered as an independent risk factor for EAD (Odds ratio 3.49, P = 0.002). The adjusted hazard of one-year graft loss was significantly increased in the delayed clearance group (hazard ratio 6.69, P = 0.001). In conclusion, peri-transplant delayed lactate clearance may be a strong predictor for EAD and poor liver graft outcomes.
