Research Article: Cytokine Storm Syndrome Triggered by Extracorporeal Membrane Oxygenation in Pediatric Patients

Date Published: 2023-06-13

Abstract:
Cytokine storm syndrome (CSS) is a serious and potentially life-threatening condition caused by severe systemic inflammation, immune activation, and a positive feedback loop of cytokine release. Typically triggered by systemic infection, malignancy, monogenic or rheumatic disease, similar patterns of hyper-inflammation have been seen in patients undergoing cardiopulmonary bypass (CPB) and in patients treated with extracorporeal membrane oxygenation (ECMO). Typical treatments used for the prevention and treatment of CPB/ECMO-induced hyper-inflammation have not been shown to be substantially effective. Two patients suffering from ECMO-related CSS were identified by their severe hyper-inflammatory profile and life-threatening sequelae of vasodilatory shock and respiratory failure. Anakinra, an interleukin-1 receptor antagonist, was employed as specific cytokine-directed therapy for the treatment of CSS in these two patients to good effect, with significant improvement in hyper-inflammation and cardiorespiratory status. The use of cytokine-directed therapies in CPB/ECMO-related CSS has great potential to improve the treatment and outcomes of this serious condition.

Introduction:
Cytokine storm syndrome (CSS) is a serious and potentially life-threatening condition caused by severe systemic inflammation, immune system activation, and a positive feedback loop of cytokine release. This pattern of hyper-inflammation can result from many different triggers, including but not limited to monogenic diseases, systemic viral infections, chimeric antigen receptor (CAR) T-cell therapy, in response to rheumatic disease, and with genetic immunodeficiencies [1,2]. The resultant release of…
