Cell-Free and Concentrated Ascites Reinfusion Therapy for Decompensated Liver Cirrhosis.

Abstract

Cell-free and concentrated ascites reinfusion therapy (CART) is expected to improve symptoms associated with refractory ascites of the decompensated liver cirrhosis patients. The aim of this study was to evaluate the safety and efficacy of the CART system performed on the decompensated liver cirrhosis patients. In this retrospective observational study, we evaluated 24 CART processes performed on 11 patients with decompensated liver cirrhosis. We evaluated the effectiveness and adverse events during CART procedures. The amounts of collected and concentrated ascites were 4491.7 ± 2222.8 mL (mean ± SD), respectively, and the concentration ratio was 22.4 ± 15.3 times, respectively. The amount of collected protein in ascites was 2.3 ± 0.5 g/dL, and concentration ratio of protein was 8.2 ± 9.4 times. Serum protein level was not significantly different between before and after CART sessions. Thus, CART allowed for the reduction of doses of albumin preparations (Alb) to be administered. CART has been reported to cause two adverse reactions: elevation of body temperature and decrease in blood pressure. In our study, decreased blood pressure was not observed even in patients with > 5 L of ascites drained. Although a transient elevation in body temperature was seen in only one patient, this febrile patient immediately returned to normal body temperature with the use of NSAIDs. In patients with refractory ascites of decompensated liver cirrhosis in whom complete cure cannot be expected, CART improves their QOL and, in terms of medical economy, allows for the reduction of doses of Alb. CART can be effectively applied as a palliative procedure for refractory ascites of decompensated liver cirrhosis patients.
