Combined Liver-Kidney Transplantation With Preformed Anti-human Leukocyte Antigen Donor-Specific Antibodies

Introduction: the impact of preformed donor-specific anti-human leukocyte antigen (HLA) antibodies (pDSAs) after combined liver-kidney transplantation (CLKT) is still uncertain. Methods: we conducted a retrospective study in 8 European high-volume transplant centers and investigated the outcome of 166 consecutive CLKTs, including 46 patients with pDSAs. Results: patient survival was lower in those with pDSAs (5-year patient survival rate of 63% and 78% with or without pDSA, respectively; P = 0.04). The presence of pDSAs with a mean fluorescence intensity (MFI) ≥ 5000 (hazard ratio 4.96; 95% confidence interval: 2.3-10.9; P < 0.001) and the presence of 3 or more pDSAs (hazard ratio 6.5; 95% confidence interval: 2.5-18.8; P = 0.05) were independently associated with death. The death-censored liver graft survival was similar in patients with or without pDSAs. Kidney graft survival was comparable in both groups. (The 1- and 5-year death-censored graft survival rates were 91.6% and 79.5%, respectively, in patients with pDSAs and 93% and 88%, respectively, in the donor-specific antibody [DSA]-negative group, P = not significant). Despite a higher rate of kidney graft rejection in patients with pDSAs (5-year kidney graft survival rate without rejection of 87% and 97% with or without pDSAs, respectively; P = 0.04), kidney function did not statistically differ between both groups at 5 years post-transplantation (estimated glomerular filtration rate 45 ± 17 vs. 57 ± 29 ml/min per 1.73 m2, respectively, in patients with and without pDSAs). Five recipients with pDSAs (11.0%) experienced an antibody-mediated kidney rejection that led to graft loss in 1 patient. Conclusion: our results suggest that CLKT with pDSAs is associated with a lower patients' survival despite good recipients', liver and kidney grafts' outcome

Impact of early remote organ dysfunction on long-term survival after liver transplantation

International audienceBackground: Attention is focused on graft function although extrahepatic organ dysfunction often occurs. Renal failure, cardiovascular events and sepsis have individually shown a significant impact on short- and long-term outcomes. The aim of the study was to identify how extrahepatic organ dysfunction (EROD) and allograft dysfunction (EAD) may be associated and their relative impact on long-term survival.Methods: A retrospective study was conducted in a unicentric cohort of 294 patients transplanted between 2009 and 2014. The composite endpoint EROD was defined as requirement during the hospitalization of de novo renal replacement therapy, reintubation/ventilation > 7 days or cardiovascular event. Donor and recipient characteristics were evaluated as predictive of EROD in uni- and multivariate analysis. Main endpoint was overall survival evaluated by Kaplan-Meier method.Results: EROD occurred in 91 patients (31%) among whom 42 also experienced EAD (46%). Predicting factors associated with EROD were IL6 level (P = 0.002) and lab-MELD (P < 0.001). Only patients experiencing both EAD and EROD had a worse survival (P = 0.001). In patients without EAD, time to normalization of bilirubin and INR were longer in patients with EROD compared to those without EROD (P = 0.002 and P = 0.008 respectively).Conclusions: The composite endpoint described as early remote organ dysfunction could be used as a predictive factor after transplantation and should be included in future studies together with early allograft dysfunction. Identifying patients in whom EROD and EAD occur together or one after the other could help to better predict long-term outcomes

Liver transplantation in critically ill patients: Preoperative predictive factors of post-transplant mortality to avoid futility

International audienceBACKGROUND:The allocation of liver transplants to patients with acute liver failure (ALF) and acute-on-chronic liver failure (ACLF) with multi-organ failure who are admitted in ICU remains controversial due to their high post-transplant mortality rate and the absence of identified mortality risk factors.METHODS:We performed a single-center retrospective cohort study to determine the post-transplant mortality rate of patients with ALF and ACLF requiring ICU care prior to liver transplant (LT) and identified pretransplant factors of post-transplant mortality.RESULTS:Eighty-four patients (29 with ALF and 55 with ACLF) received a liver transplant while they were hospitalized at the ICU. Their mean model for end-stage liver disease (MELD) score was 41, and their mean sequential organ failure assessment (SOFA) was 15 the day before transplant. The overall 1-year survival rate was 66%. In multivariate analysis, pretransplant lactate level and acute respiratory distress syndrome (ARDS) were the only two independent factors associated with post-transplant mortality. The absence of ARDS and a pretransplant lactate level80%).CONCLUSIONS:Low lactatemia lactate level and the absence of ARDS could be useful criteria in selecting those patients in ICU who could be eligible for liver transplant

Alcohol Consumption the Day of Liver Transplantation for Alcohol‐Associated Liver Disease Does Not Affect Long‐Term Survival: A Case‐Control Study

International audienceAlcohol abstinence before liver transplantation (LT) for alcohol-associated liver disease (ALD) is required for every candidate. Some listed patients might relapse, resulting in LT for patients nonabstinent during the pretransplant period. Long-term survival outcomes of these patients have never been studied. We sought to determine whether alcohol consumption on the day of the LT influenced long-term survival after LT. We conducted a retrospective case-control study among French LT centers. Cases were defined as recipients between January 1995 and December 2007 having positive blood and/or urine alcohol levels the day of LT. Each case was paired with 2 controls corresponding to patients transplanted for ALD during the same trimester. Patients were classified into 3 categories per alcohol consumption: abstainers, occasional or transitory excessive consumers, or patients with a sustained excessive consumption (daily consumption >20-30 g/day). During the study period, 3052 LTs for ALD were conducted in France. We identified 42 cases paired with 84 controls. Median blood alcohol level was 0.4 g/L (range 0.1-4.1 g/L) and median urine alcohol level was 0.2 g/L (range 0.1-2.0 g/L). Median follow-up period until death or censoring was 12.9 years (CI95% = [12.3; 13.6]). Long-term survival was not different between the groups. Relapse to any alcohol consumption rate was higher in the case group (59.5%) than in the control group (38.1%, odds ratio 2.44; CI95% = [1.13; 5.27]), but sustained excessive consumption was not significantly different between the groups (33.3% versus 29.8% in case and control groups respectively, χ2 = 0.68). Rates of recurrent cirrhosis and cirrhosis-related deaths were more frequent in the case group. Liver transplantation for nonabstinent patients during the immediate pretransplant period does not result in impaired long-term survival despite higher relapse and recurrent cirrhosis rates
