Acute-on-chronic liver failure (ACLF) is the most life-threatening complication of cirrhosis. Prevalence and outcomes of ACLF have recently been described in hospitalized patients with cirrhosis. However, no data is currently available on the prevalence and the risk factors of ACLF in outpatients with cirrhosis. The aim of this study was to evaluate incidence, predictors and outcomes of ACLF in a large cohort of outpatients with cirrhosis.


A total of 466 patients with cirrhosis consecutively evaluated in the outpatient clinic of a tertiary hospital were included and followed up until death and/or liver transplantation for a mean of 45±44months. Data on development of hepatic and extrahepatic organ failures were collected during this period. ACLF was defined and graded according to the EASL-CLIF Consortium definition.


During the follow-up, 118 patients (25%) developed ACLF: 57 grade-1, 33 grade-2 and 28 grade-3. The probability of developing ACLF was 14%, 29%, and 41% at 1year, 5years, and 10years, respectively. In the multivariate analysis, baseline mean arterial pressure (hazard ratio [HR] 0.96; p=0.012), ascites (HR 2.53; p=0.019), model of end-stage liver disease score (HR 1.26; p<0.001) and baseline hemoglobin (HR 0.07; p=0.012) were found to be independent predictors of the development of ACLF at one year. As expected, ACLF was associated with a poor prognosis, with a 3-month probability of transplant-free survival of 56%.


Outpatients with cirrhosis have a high risk of developing ACLF. The degree of liver failure and circulatory dysfunction are associated with the development of ACLF, as well as low values of hemoglobin. These simple variables may help to identify patients at a high risk of developing ACLF and to plan a program of close surveillance and prevention in these patients.


There is a need to identify predictors of acute-on-chronic liver failure (ACLF) in patients with cirrhosis in order to identify patients at high risk of developing ACLF and to plan strategies of prevention. In this study, we identified four simple predictors of ACLF: model of end-stage liver disease (MELD) score, ascites, mean arterial pressure and hemoglobin. These variables may help to identify patients with cirrhosis, at a high risk of developing ACLF, that are candidates for new strategies of surveillance and prevention. Anemia is a potential new target for treating these patients.


Question posée
Prévalence et facteurs de risque d'une insuffisance hépatique aiguë chez les patients ambulatoires atteints de cirrhose.
Question posée
Les patients ambulatoires atteints de cirrhose courent un risque élevé de développer une insuffisance hépatique aiguë. Le degré d'insuffisance hépatique et l'hypotension et l'anémie sont associés au développement d'une insuffisance hépatique aiguë. Ces variables simples peuvent aider à identifier les patients à haut risque de développer des ACLF et à planifier un programme de surveillance étroite et de prévention chez ces patients.
