We performed post-marketing surveillance to evaluate the safety and efficacy of cell-free and concentrated ascites reinfusion therapy (CART). In total, 356 CART sessions in 147 patients at 22 centers were performed. The most common primary disease was cancer (128 cases, 300 sessions). Mean amount of ascites collected was 3.7 L, and mean concentration ratio was 9.2. Mean amount of reinfused protein was 67.8 g (recovery rate, 72.0%). Performance status, dietary intake, urine volume, body weight and abdominal circumference were significantly improved after CART. Body temperature increased significantly, by 0.3°C on average. Concomitant steroids and/or NSAIDs use before reinfusion was significantly and negatively associated with increases in body temperature. Most adverse events were fever and chills. This study examined a large number of patients compared with previous studies, and showed that CART is an effective and relatively safe treatment for refractory ascites, such as malignant ascites.
Objective Ascites becomes refractory to diuretics in cirrhotic patients, who then require repeated large-volume paracentesis or cell-free and concentrated ascites reinfusion therapy (CART). The objective of this study was to confirm the safety and efficacy of CART, evaluate the actual situations with respect to the prescription of diuretics and determine the role of diuretics after the introduction of CART. Patients and Methods We recruited 34 cirrhotic patients who received CART with concomitant diuretics using furosemide (76.2%), spironolactone (48.5%), thiazide (4.0%) and tolvaptan (53.5%) from a post-marketing surveillance of CART. Results CART improved the tested clinical indices, i.e., body weight, abdominal circumference, performance status, dietary intake, total protein and albumin. The intervals of CART sessions were significantly prolonged in patients who received tolvaptan (mean, 22.5 days) compared to those not receiving tolvaptan (mean, 10.8 days) (p<0.001). The drop-out rate was significantly decreased in patients receiving tolvaptan compared to those not receiving tolvaptan when drop-out was defined as paracentesis (p<0.05). Conclusion We confirmed that CART is an effective treatment for refractory ascites occurring in cirrhotic patients. The administration of tolvaptan in combination with CART leads to a significantly reduced rate of ascites accumulation.
Background and Aim: Cell-free and concentrated ascites reinfusion therapy (CART) has been performed against cirrhotic ascites, one of the most common complications seen in patients with decompensated cirrhosis. The aim of this study is to investigate its safety and efficacy, and differences in clinical profiles from CART against malignancy-related ascites with different pathological background. Methods: The present investigation involved a sub-analysis of data obtained from a prospective observational study of CART performed at 22 centers. The condition of each procedure, therapeutic options, laboratory data, performance status, dietary intake, and abdominal circumference of participants were analyzed. Clinical parameters were compared between before and after CART, with or without albumin infusion, and also primary diseases including cirrhosis and malignant disease. Results: Between January 2014 and January 2015, a total of 48 and 275 CART procedures were performed in patients with cirrhosis and malignancies. In cirrhotic patients, serum albumin concentration increased significantly in groups both with and without concomitant albumin infusion (P = 0.002 and P = 0.023), and no significant difference in CART interval was seen between these groups (P = 0.393). CART interval was not significantly different between cirrhosis and malignancy groups (P = 0.334). Dietary intake significantly improved after CART in both groups (P = 0.043 and P < 0.001). Adverse events were with no clinical significance as observed in patients with malignancies. Conclusions: Cell-free and concentrated ascites reinfusion therapy was performed safely and effectively in patients with ascites related to decompensated cirrhosis and offers the potential efficacy to maintain plasma colloid osmotic pressure after paracentesis as well as in patients with malignancy.
