Introduction: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. As such, circulating cytokines and danger- and pathogen-associated molecular patterns (such as endotoxins) are recognized as central in the pathogenesis of sepsis and organ dysfunction. Removing these compounds by extracorporeal blood filtration, commonly considered blood purification, may improve the septic patients' condition. This study aimed to assess the vaso-inotropic support evolution over time in pediatric patients with vasoplegic shock treated with oXiris©.
Methods: All patients aged below 18 years admitted at the Paris Saclay University Quaternary Pediatric Intensive Care Unit with vasoplegic shock and acute kidney injury and treated with oXiris© between October 2017 and January 2020 were included. The vaso-inotropic score and the 28-day mortality were assessed. Improvement under treatment was defined as a 50% decrease in the vaso-inotropic score following 24 h of oXiris© therapy.
Results: Eleven pediatric patients aged 2-15 years and weighing 11-60 kg were admitted with vasoplegic shock and acute kidney injury. They received thirteen sessions of oXiris© therapy for septic shock (N = 7) and liver failure (N = 6). Eight patients did not improve their condition during the session, and five ultimately died (37.5% survival). Five patients improved, decreasing their inotropic support by >50% in 24 h. Among them, four survived (80%).
Conclusion: Hemofiltration and extracorporeal blood purification with oXiris© can be used in pediatric patients with vasoplegic shock with rapid improvement in hemodynamics in selected patients.
