Acute mechanical hemolysis as a complication of extracorporeal photopheresis in a low ‐weight child

Graft‐versus‐host disease (GVHD) is a complication of allogeneic hematopoietic stem cell transplantation with high morbidity and mortality. Extracorporeal photopheresis (ECP) is an effective therapy for treating medication‐refractory GVHD, however, there is scant evidence of whether ECP can be safely performed in patients weighing less than 15 kg. Here, we report the implementation of a successful protocol to perform ECP in a 21‐month‐old, 10.6 kg female with medication‐refractory GVHD. Our initial ECP treatment resulted in significant hemolysis that was most likely mechanical. After procedural adjustments that included modifying the anticoagulation dose and whole blood:anticoagulant ratio, as well as whole blood processing time, the patient tolerated future procedures safely without hemolysis or other adverse events. With appropriate technical modifications, we provide a framework for safely performing ECP in children less than 15 kg.
