Abstract
BACKGROUND & AIMS: Fractionated plasma separation and adsorption (FPSA) is an extracorporeal procedure that supports liver function by removing endogenous toxins that cause complications from acute-on-chronic liver failure (AOCLF). We performed a randomized trial to investigate survival of patients with AOCLF treated with FPSA. METHODS: Patients with AOCLF were randomly assigned to groups given a combination of FPSA and standard medical therapy (SMT) (FPSA group, n=77) or only SMT (n=68). The Prometheus® liver support system was used to provide 8-11 rounds of FPSA (minimum of 4 h each) for 3 weeks. Primary endpoints were survival probabilities at days 28 and 90, irrespective of liver transplantation. RESULTS: Baseline clinical parameters and number of transplanted patients were similar between study arms. Serum bilirubin decreased significantly in the FPSA group but not in the SMT group. In an intention-to-treat analysis, the probabilities of survival on day 28 were 66% in the FPSA group and 63% in the SMP group (p=0.70); on day 90, they were 47% and 38%, respectively (p=0.35). Baseline factors independently associated with poor prognosis were high SOFA score, bleeding, female sex, spontaneous bacterial peritonitis, intermediate increases in serum creatinine concentration, and combination of alcoholic and viral etiology of liver disease. There were no differences between the two groups in the incidence of side effects. CONCLUSIONS: Among all patients with AOCLF, extracorporeal liver support with FPSA does not increase the probability of survival. Further studies are needed to assess whether therapy might be beneficial in specific subsets of patients.
