Mixed T cell CHIMERISM in bone marrow at day+30 after allogeneic stem cell transplantation: Correlation with acute GVHD grades III–IV and no impact on relapse and overall survival

Abstract: Objectives Early chimerism analysis is important to assess engraftment in allogeneic hematopoietic stem cell transplantations. Methods We retrospectively investigated the impact of T‐cell chimerism at day 30 in bone marrow on acute graft‐versus‐host disease (aGVHD), relapse, and overall survival in 142 adult allo‐transplanted patients. Results The majority of patients (89%) received myeloablative conditioning and 90% have undergone T‐cell replete donor graft. At day 30, 103 patients showed T‐complete chimerism… Show more

“…For example, a recipient’s professional APCs such as dendritic cells ( 6 , 7 ) or epithelial cells ( 8 ) activate donor T lymphocytes by presenting pleomorphic transplantation Ags, present in the recipient but absent in the donor. Surviving recipient T cells can also play a role in initiation or maintenance of tissue inflammation, although recipient T cell subsets can as well regulate transplant immunity ( 9–13 ). In this context, recipient T cell–generated modulatory cytokines have been shown to dampen donor T cell activation and the subsequent cascade of events that results in GVHD ( 14 , 15 ).…”
