Abstract

Idiopathic cytopenias are frequently observed in patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We have previously reported the effect of graft-versus-host disease (GVHD) on bone marrow (BM) in murine models, indicating that the osteoblast injury mediated by donor T cells was associated with bone marrow suppression and delayed immune reconstitution ("BM GVHD"). In this study, we prospectively evaluated the relevance of these findings in 51 patients. Patients with chronic GVHD manifested the loss of osteoblasts, contributing to cytopenic symptoms (P = 0.0427, vs. patients without cytopenic symptoms). The loss of osteoblasts was significantly associated with the extensive type of chronic GVHD (P = 0.012) and flow cytometric analyses revealed lower numbers of CD19+ B cells and significantly increased CD4/CD8 ratio (P = 0.0002) in these patients. Our data for the first time summarize the detailed analyses of the effect of GVHD on BM in the clinical allo-HSCT patients.
