Abstract:
OBJECTIVE:To explore the relationship between occurrence of acute graft-versus-host disease (aGVHD) and various immune cell composition in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).
METHODS:The clinical data of 104 patients with AML undergoing allo-HSCT in our hospital were retrospectively analyzed, and the hematopoietic reconstitution and occurrence of GVHD were analyzed. Flow cytometry was used to detect the proportion of various types of immune cells in the grafts, the number of graft composition in patients with different degrees of aGVHD was calculated and compared, and to analyze the correlation between the severity of aGVHD in AML patients after allo-HSCT and the immune cell components in the graft.
RESULTS:There was no significant difference in the time of hematopoietic reconstitution between the high number group of total number of nucleated cells (TNC) and the low number group, while the time of neutrophil and platelet reconstruction in the high number of CD34 group was significantly faster than that in the low number of CD34 group (P＜0.05), and the total hospital stay also tends to be shorten. Compared with patients in 0-Ι aGVHD group, both HLA-matched and HLA-haploidentical transplantation, the infusion amounts of CD3+ cells, CD3+CD4+ cells, CD3+CD8+ cells, NK cells and CD14+ monocytes were higher in patients of Ⅱ-Ⅳ aGVHD group， but the difference was not statistically significant (P>0.05); In addition, in patients with HLA-haploidentical transplantation, the number of CD4+CD25+ cells in Ⅱ-Ⅳ aGVHD group was significantly lower than that in 0-Ι aGVHD group (P<0.05), and the same trend was also observed in HLA-matched transplanted patients, but the difference was not significant (P=0.078).
CONCLUSION:High number of CD34+ cells in the graft is beneficial to hematopoietic reconstitution in AML patients. To a certain degree, high number of CD3+ cells, CD3+CD4+ cells, CD3+CD8+ cells, NK cells and CD14+ cells tend to increase the occurrence of aGVHD, but high number of CD4+CD25+ regulatory T cells is beneficial to reduce the incidence of aGVHD in AML patients.
