Use of cidofovir with extracorporeal membrane oxygenation to treat adenovirus-associated acute respiratory distress syndrome in paediatric patients— a case series

What is known and objective: Reports of cidofovir dosing with extracorporeal membrane oxygenation (ECMO) support are limited. This case series describes our clinical experience and provides a literature review regarding cidofovir dosing in paediatric patients requiring ECMO support. Case summary: Three patients with adenovirus-associated acute respiratory distress syndrome (ARDS) were treated with cidofovir while requiring ECMO support. A 27-month-old patient was treated with cidofovir 1 mg/kg/dose three times weekly, and a 19-month-old patient and an 18-year-old patient were treated with cidofovir 5 mg/kg/dose weekly. What is new and conclusion: This case series describes the dosing and positive clinical response of cidofovir in paediatric patients with adenovirus-associated ARDS requiring ECMO support.
