BACKGROUNDA liver support therapy, named molecular adsorbents recirculating system (MARS), has been used for more than 700 liver failure patients in China. We made here a summary to evaluate the effects of MARS treatment in different applications with emphasis on hepatitis B virus (HBV) based liver failure.
METHODSThis report analyzed data of 252 patients (mean age (44.9+/- 12.7) years) in three groups: acute severe hepatitis (ASH), subacute severe hepatitis (SSH) and chronic severe hepatitis (CSH). The largest group was CSH (156 patients, 61.9%), and 188 patients (74.6%, 188/252) were infected with HBV.
RESULTSMARS treatments were associated with significant reduction of albumin bound toxins and water-soluble toxins. Most of the patients showed a positive response with a significant improvement of multiple organ function substantiated by a significant increase in prothrombin time activity (PTA) and median arterial pressure (MAP). There was a decrease in hepatic encephalopathy (HE) grade and Child-Turcotte-Pugh (CTP) scale. Thirty-nine of 188 HBV patients (20.7%) dropped out of the commendatory consecutive therapy ending with lower survival of 43.6% while the rest of the 149 patients had a survival rate of 62.4%. Survival within the ASH and SSH groups were 81.2% and 75.0%, respectively. In the CSH group, end stage patients were predominant (65/151, 43%), whereas the early and middle stage patients had a better prognosis: early stage survival, including orthotopic liver transplantation (OLT) survival of 91.7%, middle stage survival of 75%, end stage survival of 33.8%.
CONCLUSIONSMARS continues to be the most favorable extracorporeal treatment for liver support therapy in China for a wide range of conditions, including the majority of hepatitis B related liver failure conditions. The appropriate application of MARS for the right indications and stage of hepatic failure, as well as the fulfillment of prescribed treatments, will lead to the optimal therapeutic result.

OBJECTIVETo analyze the preoperative risk factors on liver transplant recipients with acute renal failure(ARF), and to evaluate renal replacement therapy (RRT) as a transitonary therapy before liver transplantation.
METHODSLiver transplant recipients with acute renal failure treated with renal replacement therapy between January 1st, 2001 and January 1st, 2008 in our center were retrospected. Clinical characteristics, the kinds of RRT and prognosis were analyzed; Logistic regression was applied to analyze the parameters that can forecast the motality of the liver transplant recipients with acute renal failure.
RESULTSOf the patients who received RRT, 30% survived to liver transplantation, 67.5% died while waiting for liver transplantation. The dead had a higher multiple organ dysfunction score (MODS), and lower mean arterial pressure than those survived to liver transplantation. There was no significant difference in the duration of RRT between continuous renal replacement therapy (CRRT) patients and hemodialysis patients. CRRT patients had a higher MODS, lower mean arterial pressure, lower serum creatinine than hemodialysis patients. Lower mean arterial pressure was statistically associated with higher risk of mortality.
CONCLUSIONThough mortality was high, RRT helps part (30%) of patients survive to liver transplantation. Therefore, considering the high mortality without transplantation, RRT is acceptable for liver transplant recipients with ARF.

BACKGROUND/AIMS: The effect of high-flux (HF) dialysis on mortality rates could vary with the duration of dialysis. We evaluated the effects of HF dialysis on mortality rates in incident and prevalent hemodialysis (HD) patients. METHODS: Incident and prevalent HD patients were selected from the Clinical Research Center registry for end-stage renal disease (ESRD), a Korean prospective observational cohort study. Incident HD patients were defined as newly diagnosed ESRD patients initiating HD. Prevalent HD patients were defined as patients who had been receiving HD for > 3 months. The primary outcome measure was all-cause mortality. RESULTS: This study included 1,165 incident and 1,641 prevalent HD patients. Following a median 24 months of follow-up, the mortality rates of the HF and low-flux (LF) groups did not significantly differ in the incident patients (hazard ratio [HR], 1.046; 95% confidence interval [CI], 0.592 to 1.847; p = 0.878). In the prevalent patients, HF dialysis was associated with decreased mortality compared with LF dialysis (HR, 0.606; 95% CI, 0.416 to 0.885; p = 0.009). CONCLUSIONS: HF dialysis was associated with a decreased mortality rate in prevalent HD patients, but not in incident HD patients.
