Aim
The management of refractory ascites is critical for the treatment of patients with decompensated cirrhosis. This study aimed to evaluate the feasibility and safety of cell-free and concentrated ascites reinfusion therapy (CART) in patients with cirrhosis and refractory ascites, with a focus on changes in coagulation and fibrinolytic factors in ascitic fluid following CART. Patients and
Conclusion
CART is an effective and safe approach for the treatment of refractory ascites that allows the intravenous reinfusion of coagulation and fibrinolytic factors in the filtered and concentrated ascites.
Methods
This was a retrospective cohort study including 23 patients with refractory ascites undergoing CART. Serum endotoxin activity (EA) before and after CART and the levels of coagulation and fibrinolytic factors and proinflammatory cytokines in original and processed ascitic fluid were measured. The Ascites Symptom Inventory-7 (ASI-7) scale was used for subjective symptom assessment before and after CART.
Results
Body weight and waist circumference significantly decreased after CART, whereas serum EA did not significantly change after CART. Similar to the previous reports, ascitic fluid concentrations of total protein, albumin, high-density lipoprotein cholesterol, γ-globulin, and immunoglobulin G levels were significantly increased after CART; mild elevations in body temperature and interleukin 6 and tumor necrosis factor-alpha levels in ascitic fluid were also observed. Importantly, the levels of antithrombin-III, factor VII, and X, which are useful for patients with decompensated cirrhosis, were markedly increased in the reinfused fluid during CART. Finally, the total ASI-7 score was significantly lower following CART, compared with the pre-CART score.
