    Abstract:
    BACKGROUND: The prognosis of pediatric acute liver failure (PALF) has been significantly improved by emergency orthotopic liver transplantation (OLT). Since 2004, the molecular adsorbent recirculating system (MARS) has been proposed as a bridging procedure. The aim of our study was to assess its efficacy in children with PALF. PATIENTS AND METHODS: Since 1999 we performed treatment of 39 fulminant hepatic failure (FHF) cases with MARS. Since September 2004 we treated 6 pediatric patients with FHF who were of mean age 10.6 years (range, 3-15 years) including 4 females and 2 males. In 3 cases the cause of FHF was unknown; in 2 cases, it was induced by paracetamol overdose; and in 1, by acute hepatitis B virus. Inclusion criteria were: bilirubin >15 mg/dL; creatinine >or=2 mg/dL; encephalopathy grade >II; and International normalized ratio (INR) >2.5. Other estimated parameters were: AST and ALT serum levels, lactate, and urine volume. Neurological status was monitored using the Glasgow Coma Scale (GCS). Continuous MARS treatment was performed in all patients with a kit change every 8 hours. Intensive care unit (ICU) treatment was applied to optimize regeneration and to prevent cardiovascular complications. RESULTS: We observed a significant improvement among levels of bilirubin (P< .009), ammonia (P< .005), creatinine (P< .02), GCS (P< .002), and predictive criteria and as Sequential Organ Failure Assessment (SOFA) and Pediatric End-Stage Liver Disease (PELD). Three children underwent OLT: 1 died after 5 days due to primary nonfunction and 2 children are alive after a median follow-up of 14 months. In 2 children the MARS treatment led to resolution of clinical status without liver transplantation. One child died before OLT due to sepsis and multiorgan failure. CONCLUSIONS: We concluded that application of the MARS liver support device in combination with experienced ICU management contributed to improve the clinical status in children with PALF awaiting liver transplantation.
