Extracorporeal cytokine adsorption as therapeutic option for immune effector cell-associated neurotoxicity syndrome

Abstract With the rising number of patients receiving chimeric antigen receptor T-cells, the treatment of this therapy’s complications is of growing concern to intensivists and neurologists. We used extracorporeal cytokine adsorption as an add-on therapy in a patient suffering from immune effector cell-associated neurotoxicity syndrome. Interleukin-6 level, which as a readily available parameter is generally used to evaluate course of disease, was rapidly reduced using this method. The patient made a full recovery and is still in hematological remission.
