CD34 Chimerism Directed Donor Lymphocyte Infusion With or Without Azacitidine Results in Reduced Relapse and Superior Overall Survival When Full Donor Chimerism is Achieved in Allogeneic Stem Cell Transplant Recipients With Acute Myeloid Leukaemia/Myelodysplastic Syndrome.

Background: Regular monitoring of CD34 donor chimerism (DC) is a highly sensitive method of predicting relapse in allogeneic stem cell transplant (alloHSCT) recipients with AML/MDS. A fall of CD34 DC below 80% is an indicator of ensuing relapse. There are limited studies assessing the efficacy of donor lymphocyte infusion (DLI) triggered by mixed CD34 DC (MDC), in addressing falling chimerism.

Cardiovascular and Metabolic Risk Incidence Among Adult Allogeneic Stem Cell Transplant Recipients: A Narrative Review.

Advances in allogeneic hematopoietic stem cell transplantation (alloHSCT) and supportive care over the past decade have reduced transplant and relapse-related mortality, leading to a greater number of long-term survivors. However, transplant-related late effects, such as cardiovascular disease (CVD) and metabolic diseases, are becoming significant concerns for this group. This review aims to address several key questions regarding cardiovascular late effects in alloHSCT recipients, including the long-term incidence of CVD-related events, the prevalence of risk factors, screening and management recommendations, and evidence for screening and prevention strategies.

Donor Lymphocyte Infusion (DLI) post allogeneic stem cell transplant (allo-SCT) in Acute Myeloid Leukemia (AML) and High-Grade Myelodysplastic Syndrome (MDS). A longitudinal retrospective study using peripheral blood (PB) CD34 and CD3 donor chimerism (DC) monitoring.

Introduction: This longitudinal study was based on the outcomes of Donor Lymphocyte Infusion (DLI) for falling peripheral blood (PB) CD34 and CD3 donor chimerism (DC).

Methods: From 2012 to 2018, data was collected from the BMT database and electronic medical records (EMR). The primary objective was to compare the indication for DLI based on falling PB CD34 or CD3 DC in patients post allo-SCT for AML and MDS and their overall survival (OS).
