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

Alcohol 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 (CI_95% = [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; CI_95% = [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.

Liver stiffness measurement predicts long-term survival and complications in non-alcoholic fatty liver disease

BACKGROUND AND AIMS

In non-alcoholic fatty liver disease (NAFLD), fibrosis is the strongest prognostic factor and can be assessed by non-invasive methods. We evaluated the ability of liver stiffness measurement (LSM) to predict overall survival and liver, cardiovascular and oncologic complications.

METHODS

We prospectively collected data on 2251 consecutive NAFLD patients (mean age 59 years, male 53%, mean body mass index 28 kg/m² ) in two centres. At inclusion, all patients had LSM, clinical and biological evaluation. During follow-up, we recorded cardiovascular events, cancers, liver complications, liver transplantation and death. The primary endpoint was overall survival. Survival curves according to LSM were first performed using Kaplan-Meier method for the primary endpoint, and Aalen-Johansen method for secondary outcomes to take into account competitive risks. In a second step, a Cox proportional hazard model analysis was done to identify independent predictors of overall survival.

RESULTS

Median follow-up was 27 months [IQR: 25-38]. Fifty-five patients died and three patients had liver transplantation. Overall survival significantly decreased as baseline LSM increased. Twenty-one patients (0.9%) had a liver event, 142 (6.3%) developed cancer (excluding HCC) and 151 (6.7%) had a cardiovascular event during follow-up. By multivariable analysis, independent predictors of overall survival were as follows: baseline LSM (adjusted HR (aHR) = 2.85 [1.65-4.92], P = .0002), age (aHR = 1.11 [1.08-1.13], P < .0001) and male sex (aHR = 2.05 [1.17-3.57], P = .012). Patients with elevated LSM were also more likely to develop cardiovascular, and liver events but not other cancers.

CONCLUSION

LSM can be used to predict survival, cardiovascular and liver complications in NAFLD patients.

Increased liver stiffness is associated with mortality in HIV/HCV coinfected subjects: The French nationwide ANRS CO13 HEPAVIH cohort study

Background

The association between liver stiffness measurements (LSM) and mortality has not been fully described. In particular the effect of LSM on all-cause mortality taking sustained virological response (SVR) into account needs further study.

Methods

HIV/HCV participants in the French nation-wide, prospective, multicenter ANRS CO13 HEPAVIH cohort, with ≥1 LSM by FibroScan (FS) and a detectable HCV RNA when the first valid FS was performed were included. Cox proportional hazards models with delayed entry were performed to determine factors associated with all-cause mortality. LSM and SVR were considered as time dependent covariates.

Results

1,062 patients were included from 2005 to 2015 (69.8% men, median age 45.7 years (IQR 42.4–49.1)). 21.7% had baseline LSM >12.5 kPa. Median follow-up was 4.9 years (IQR 3.2–6.1). 727 (68.5%) were ever treated for HCV: 189 of them (26.0%) achieved SVR. 76 deaths were observed (26 liver-related, 10 HIV-related, 29 non-liver-non-HIV-related, 11 of unknown cause). At the age of 50, the mortality rate was 4.5% for patients with LSM ≤12.5 kPa and 10.8% for patients with LSM >12.5 kPa. LSM >12.5 kPa (adjusted Hazard Ratio [aHR] = 3.35 [2.06; 5.45], p<0.0001), history of HCV treatment (aHR = 0.53 [0.32; 0.90], p = 0.01) and smoking (past (aHR = 5.69 [1.56; 20.78]) and current (3.22 [0.93; 11.09]) versus never, p = 0.01) were associated with all-cause mortality independently of SVR, age, sex, alcohol use and metabolic disorders.

Conclusion

Any LSM >12.5 kPa was strongly associated with all-cause mortality independently of SVR and other important covariates. Our results suggest that close follow-up of these patients should remain a priority even after achieving SVR.
