ABSTRACT

BACKGROUND AND OBJECTIVES: To compare previous hemophagocytic lymphohistiocytosis criteria with adult coronavirus disease 2019 (COVID-19)-associated hyperinflammatory syndrome (cHIS) criteria for the diagnosis of hyperinflammation in pediatric patients with COVID-19. The secondary objective was to assess treatment response to intravenous (IV) anakinra in these patients. METHODS: This case series included children admitted to the PICU for COVID-19 pneumonia with hyperinflammation and treated with IV anakinra between July 2020 to April 2021. Hyperinflammatory criteria were determined for each patient. Clinical course, chest imaging, and inflammatory marker trends were assessed pre- and post-anakinra treatment. RESULTS: All patients had a cHIS criteria score of ≥5. Two patients met 2004-hemophagocytic lymphohistiocytosis criteria. Only the patient that required extracorporeal membrane oxygenation met the H-Score cut-off value. All but one patient had a decrease in their inflammatory markers and improvement in clinical status with early initiation of adjunctive IV anakinra. CONCLUSIONS: In this case series, adult cHIS criteria were successfully used to identify pediatric COVID-19 patients with hyperinflammation. Ferritin levels decreased after the early initiation of IV anakinra.
