Abstract

Background: Our group and others (Greinix BBMT 2015) have shown that higher proportions of recent thymic emigrants (RTEs: CD4+CD45RA+CD31+) at d100 are a prognostic biomarker for chronic GvHD in adults. We sought to understand whether RTEs, as well as regulatory T cells (CD4+CD25+CD127Lo) that co-express naive and recently emigrated markers (CD45RA+CD31+; Treg RTEs) were prognostic at d100 for pediatric cGvHD. Methods: Allo-HCT patients (1.5x or
