The validated Mount Sinai Acute graft-versus-host disease (aGvHD) International Consortium (MAGIC) algorithm and biomarker panels did not predict aGvHD occurrence or severity in pediatric αβT-cell/CD19 B-cell depleted haploidentical hematopoietic stem cell transplant (αβhaplo-HSCT) recipients. These findings suggest distinct aGvHD biology in the αβhaplo-HSCT setting, supporting the need for tailored biomarker studies in this unique transplant platform.
