Compliance with ethical standards

:

: Carla Kreissig was employed by the German Red Cross Blood Service West, Ratingen, Germany. She was responsible for the production of granulocyte transfusions at the German Red Cross Blood Service West, Ratingen. The other authors report no potential conflicts of interest. The authors alone are responsible for the content and redaction of the manuscript.

: For all procedures, informed consent of the donors, parents, and the teenage patients was obtained. The need for informed consent for the retrospective analysis of routinely obtained clinical data was waived by the “Research Ethics Committee of the Medical Faculty, University of Duisburg-Essen” (correspondence 15-6291-BO). The ethics committee ensured the supervision of the communications of the anonymized data.
