Abstract

Abstract: Background and Aim: The molecular adsorbent recirculating system (MARS) is the most widely used device to treat liver failure. Nevertheless, data from widespread real‐life use are lacking. Methods: This was a retrospective multicenter study conducted in all French adult care centers that used MARS between 2004 and 2009. The primary objective was to evaluate patient survival according to the liver disease and listing status. Factors associated with mortality were the secondary objectives. Results: A total of 383 patients underwent 393 MARS treatments. The main indications were acute liver failure (ALF, 32.6%), and severe cholestasis (total bilirubin >340 μmol/L) (37.2%), hepatic encephalopathy (23.7%), and/or acute kidney injury–hepatorenal syndrome (22.9%) most often among patients with chronic liver disease. At the time of treatment, 34.4% of the patients were listed. Overall, the hospital survival rate was 49% (95% CI: 44–54%) and ranged from 25% to 81% depending on the diagnosis of the liver disease. In listed patients versus those not listed, the 1‐year survival rate was markedly better in the setting of nonbiliary cirrhosis (59% vs 15%), early graft nonfunction (80% vs 0%), and late graft dysfunction (72% vs 0%) (all P < 0.001). Among nonbiliary cirrhotic patients, hospital mortality was associated with the severity of liver disease (HE and severe cholestasis) and not being listed for transplant. In ALF, paracetamol etiology and ≥3 MARS sessions were associated with better transplant‐free survival. Conclusion: Our study suggests that MARS should be mainly used as a bridge to liver transplantation. Survival was correlated with being listed for most etiologies and with the intensity of treatment in ALF. Abstract : Because the long‐term outcome of patients treated with the molecular adsorbent recirculating system (MARS) in the real life has not been well assessed, we performed a retrospective multicenter study in all French adult care centers that used MARS between 2004 and 2009. The hospital survival rate was 49% (95% CI: 44–54%) and varied from 25% to 81% depending on the diagnosis of the liver disease and the 1‐year survival rate was markedly better in listed versus not listed patients in the setting of non‐biliary cirrhosis (59% vs 15%), early graft non‐function (80% vs 0%) and late graft dysfunction (72% vs 0%) (all P < 0.001). In acute liver failure, paracetamol etiology and ≥3 MARS sessions were associated with higher transplant‐free survival.
