Dermatologic complications in pediatric patients after hematopoietic stem cell transplantation for sickle cell disease

Abstract

AbstractDermatologic complications are common following allogeneic hematopoietic stem cell transplantation, but dermatologic complications among pediatric patients undergoing hematopoietic stem cell transplantation for the treatment of sickle cell disease have been poorly characterized. In this case series of 17 patients (<21 years old) with sickle cell disease who underwent hematopoietic stem cell transplantation, 16 (94.1%) experienced one or more dermatologic complications after transplant, with the most common complications including acute or chronic mucocutaneous graft‐versus‐host disease (GVHD) (34.1% of complications), skin eruptions of unknown origin (15.9% of complications), infections (15.9% of complications), and chemotherapy‐related pigmentary changes (11.4% of complications). Patients who developed acute or chronic skin GVHD were significantly older at the time of hematopoietic stem cell transplantation. These findings highlight the need to closely monitor for dermatologic complications in pediatric patients who undergo hematopoietic stem cell transplantation for sickle cell disease and underscore the importance of involving dermatology early on when skin complications occur, although further research with a larger multicenter study could help clarify the risk for dermatologic complications and help identify potential ways to mitigate this risk.
