Abstract

Herpes simplex virus (HSV) reactivation and acyclovir resistance are common complications in immunocompromised individuals. We report a pediatric hematopoietic stem cell transplantation (HSCT) recipient who received HSV-1-specific T cells from a partially human leukocyte antigen (HLA) matched donor for severe acyclovir-resistant HSV-1 mucositis resulting in clinical improvement, reduced plasma viral load, and emergence of antiviral T cells.
