Prevention of the febrile reaction occurring on reinfusion of cell-free and concentrated autogenous ascites.

Abstract

The febrile reaction that occurs on reinfusion of ascites was studied. Intravenous reinfusion of ascites was performed 213 times in 63 cases of ascites, which were refractory to treatment with various drugs including diuretics. In order to prevent fever on reinfusion of ascites, a screen filter and a depth filter were used; the results were more favorable with the screen filter. Fibrin was considered to be one of the substances removable by the screen filter. HPLC analysis of the filtered and concentrated ascites, after passage through the screen filter, revealed a fraction corresponding to albumin. Intravenous injection of this fraction into rabbits caused fever. Although the screen filter cannot completely prevent fever on reinfusion of ascites, it appears useful to prevent fever in some patients.
