INTRODUCTION: Patients with acute-on-chronic liver failure show an aggravated hyperdynamic circulation. We evaluated, in a controlled manner, potential changes in systemic haemodynamics induced by the molecular adsorbent recirculating system (MARS) and the Prometheus system liver detoxification devices in a group of patients with acute-on-chronic liver failure. METHODS: Eighteen patients (51.2 +/- 2.3 years old; Child-Pugh score, 12.5 +/- 0.2; Maddrey score, 63.1 +/- 5.0; hepatic venous pressure gradient, 17.6 +/- 0.9 mmHg) with biopsy-proven alcoholic cirrhosis and superimposed alcoholic hepatitis were either treated with standard medical therapy (SMT) combined with MARS (n = 6) or Prometheus (n = 6) or were treated with SMT alone (n = 6) on three consecutive days (6 hours/session). Liver tests, systemic haemodynamics and vasoactive substances were determined before and after each session. RESULTS: Groups were comparable for baseline haemodynamics and levels of vasoactive substances. Both MARS and Prometheus decreased serum bilirubin levels (P < 0.005 versus SMT), the Prometheus device being more effective than MARS (P = 0.002). Only MARS showed significant improvement in the mean arterial pressure (Deltachange, +9 +/- 2.4 mmHg versus -0.3 +/- 2.4 mmHg with Prometheus and -5.2 +/- 2.1 mmHg with SMT, P < 0.05) and in the systemic vascular resistance index (Deltachange, +131.5 +/- 46.2 dyne x s/cm5/m2 versus -92.8 +/- 85.2 dyne x s/cm5/m2 with Prometheus and -30.7 +/- 32.5 dyn...
