One of the topics of discussion this week was the utilization of Molecular Adsorbent Recirculating System™ (MARS) in patients with acute liver failure.

Results: 102 patients (mean age, 40.4 years [SD, 13]) were in the modified intention-to-treat (mITT) population. The per-protocol analysis (49 conventional, 39 MARS) included patients with at least 1 session of MARS of 5 hours or more. Six-month survival was 75.5% (95% CI, 60.8% to 86.2%) with conventional treatment and 84.9% (CI, 71.9% to 92.8%) with MARS (P = 0.28) in the mITT population and 75.5% (CI, 60.8% to 86.2%) with conventional treatment and 82.9% (CI, 65.9% to 91.9%) with MARS (P = 0.50) in the per-protocol population. In patients with paracetamol-related ALF, the 6-month survival rate was 68.4% (CI, 43.5% to 86.4%) with conventional treatment and 85.0% (CI, 61.1% to 96.0%) with MARS (P = 0.46) in the mITT population. Sixty-six of 102 patients had transplantation (41.0% among paracetamol-induced ALF; 79.4% among non-paracetamol-induced ALF) (P < 0.001). Adverse events did not significantly differ between groups.
