巨细胞病毒感染对重型β-地中海贫血儿童异基因造血干细胞移植后早期T细胞亚群的影响
Impact of cytomegalovirus infections on T lymphocyte subsets in children with β-thalassemia major early after allogeneic hematopoietic stem cell transplantation
摘要
Abstract
Objective To investigate the effect of human cytomegalovirus (HCMV) infection on T lymphocyte subsets in children with β-thalassemia major (TM) during the initial 6 months after allogeneic hematopoietic stem cell transplantation (Allo-HSCT). Methods From January, 2010 to January, 2011, 35 children with TM underwent Allo-HSCT. Peripheral blood samples were obtained from the children 6 month after the transplantation to examine the changes of T lymphocytes subsets in relation to HCMV seroposirivity. Results Thirteen children were found seropositive and 22 were seronegative for HCMV. The HCMV-seropositive children had a higher CD8' cell percentage but a lower CD4' cell percentage than those without HCMV infection. Compared with those seronegative for HCMV, the children with HCMV seropositivity showed increased percentages of CD8+ cells and CD8+CD28- cells with a decreased percentage of CD8+CD28+ cells. A positive linear correlation was found between the percentages of CD8+ CD28- cells and CD8+ cells. Conclusion HCMV infection can lead to the accumulation of CD8+CD28 cells to cause increased CD8+ T cells in the peripheral Wood in TM children after Allo-HSCT. The percentages of CD8-CD28- cells has a positive linear correlation to that of CD8+ cells.关键词
