dc.description.abstract | Introduction: Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative therapeutic option for high-risk acute leukemia, but it can cause severe complications. Homeostasis of immune function plays a key role in the development of some of these complications, and regulatory T cells (Tregs) are known to have an important role in maintaining the immune homeostasis.
i Expression of Forkhead BOX P3 (FOXP3) is essential for the development of Tregs. The main aim of this study was to evaluate the potential influence of FOXP3 rs3761548 polymorphisms of donor on the outcomes of the HSCT. Methods: A total of 171 patients were enrolled in this study and genotyping was done with PCR and direct sequencing using the post-transplant samples, which showed the complete replacement of hematopoietic cells by donor. We grouped the patients according to the genotype and compared the clinical outcomes using the Log- rank test and Gray test. Results: The patients who received HSCT from the donor with rs3761548 CC genotype had higher incidence of hepatic veno- occlusive disease (HVOD) and cytomegalovirus (CMV) infection compared to those of AA or AC genotype group (24.9% vs. 8.5%, P=0.011 and 66.3% vs. 47.6%, P=0.023). Treatment-related mortality (TRM) rate of patients with AA or AC genotype was lower than that of the other patients with CC genotype (3.4% vs. 14.2%, P=0.044) resulting in the difference of overall survival. There was no difference in graft-versus-host disease (GVHD), relapse or blood stream infection (BSI) according to the rs3761548 ii genotype. In multivariate analysis, CC genotype maintained its statistical significance in the development of HVOD (HR=3.97, 95% CI=1.47-10.74) and CMV infection (HR=1.88, 95% CI=1.19- 2.97), showing lower overall survival. Conclusions: This is the first report on FOXP3 rs3761548 SNP in allogeneic HSCT and this SNP can be considered as a candidate marker for predicting the development of HVOD and CMV infection after allogeneic HSCT. | - |
