Occurrence of fever in cell-free and concentrated ascites reinfusion therapy is not related to the primary disease or nature of ascites.

Abstract

Cell-free and concentrated ascites reinfusion therapy (CART) is a treatment for refractory ascites wherein filtered and concentrated ascitic fluid is reinfused. Although fever is one of the side effects of CART, its cause is not clear. Patients who underwent at least one CART session between June 2011 and May 2021 at our medical center were retrospectively enrolled in the study. They were classified according to the primary disease and nature of ascites. Ninety patients were included in this study. Increase in body temperature (BT) after CART was observed, regardless of the primary disease and nature of ascites. The difference in temperature before and after CART did not differ based on the primary disease [cancerous (including hepatocellular carcinoma, ovarian cancer) and non-cancerous] and nature of ascites. Elevated BT and fever after CART are not related to the primary disease and nature of the ascites.
