Individualized Application of Anti-Thymocyte Globulin(ATG)in Unrelated Donor Hematopoietic Stem Cell Transplantation

This study aims to compare individualized anti-thymocyte globulin (ATG) dosing versus conventional fixed-dose regimens in unrelated donor peripheral blood stem cell transplantation (URD-PBSCT). This study notes that URD-HSCT is a key treatment for malignant hematologic diseases and severe bone marrow failure, with rapid expansion in China. However, this study identifies post-transplant CMV infection as a major challenge, adversely affecting survival and quality of life. This study finds that CMV infection compromises immunity and causes multi-organ complications. Given the high costs, long treatment cycles, and limited efficacy of current interventions, this study considers optimizing CMV prevention to be of greater value than expanding treatment options. This study asserts that effective prevention can reduce infection rates and improve overall survival (OS) and long-term prognosis. This study recognizes that ATG is widely used in URD-HSCT to prevent graft-versus-host disease (GVHD), but its dosage is significantly linked to CMV risk. This study indicates that inadequate ATG exposure increases GVHD risk, while excessive exposure raises viral reactivation (e.g., CMV, EBV) and may cause relapse. This study thus identifies balancing GVHD prevention and infection control as a key clinical goal. This study cites Remberger et al. (2004), who compared ATG doses (4-10 mg/kg) in 162 URD-HSCT patients, finding lower doses increased acute GVHD (aGVHD) and 10 mg/kg raised infection-re…
