    Abstract:
    PURPOSE: The aim of this prospective study was to evaluate the effectiveness of preconditioning molecular adsorbent recirculating system (MARS) treatment on patients with acute-on-chronic liver failure (AoCLF), who were awaiting living donor liver transplantation (LDLT). PATIENTS AND METHODS: Between January and December 2001, 10 consecutive AoCLF patients (with progressive hyperbilirubinemia (>20 mg/dl) and hepatic encephalopathy grade > or =2) were studied. MARS was used in eight of these patients who were evaluated for LDLT during 2001. Three AoCLF patients who received LDLT before clinical use of MARS were used as historical controls. RESULTS: Because of a shortage of donors, only five out of 10 patients considered for LDLT could receive transplants. Three patients were treated with MARS for 8 h the day before receiving LDLT, and all three survived. The remaining two patients who received transplants, and who were not pretreated with MARS, died from sepsis and multi-organ failure within 2 weeks. Four of the patients who did not receive transplants because of donor shortage died despite 1 or 3 MARS treatments, however bilirubin levels and grade of encephalopathy were significantly reduced in these patients. CONCLUSIONS: Results of this small pilot study suggest that MARS, by reducing the severity of jaundice and encephalopathy, might be effective as a bridging option in AoCLF patients awaiting LDLT.
