The Genotype of the Donor for the (GT)n Polymorphism in the Promoter/Enhancer of FOXP3 Is Associated with the Development of Severe Acute GVHD but Does Not Affect the GVL Effect after Myeloablative HLA-Identical Allogeneic Stem Cell Transplantation.
The FOXP3 gene encodes for a protein (Foxp3) involved in the development and functional activity of regulatory T cells (CD4+/CD25+/Foxp3+), which exert regulatory and suppressive roles over the immune system. After allogeneic stem cell transplantation, regulatory T cells are known to mitigate graft versus host disease while probably maintaining a graft versus leukemia effect. Short alleles (<=(GT)(15)) for the (GT)(n) polymorphism in the promoter/enhancer of FOXP3 are associated with a higher expression of FOXP3, and hypothetically with an increase of regulatory T cell activity. This polymorphism has been related to the development of auto-or alloimmune conditions including type 1 diabetes …
Thrombopoietin Receptor Agonists for Severe Thrombocytopenia after Allogeneic Stem Cell Transplantation: Experience of a Multicenter Study from the Grupo Español De Trasplante Hematopoyético (GETH)
Abstract Introduction Thrombocytopenia is a common complication after allogeneic hematopoietic stem cell transplantation (allo-SCT). Underlying mechanisms are poorly known and usually multifactorial. Its treatment is not well defined, mostly based in platelet transfusion. Thus, is important to identify new strategies to manage this important post-SCT complication. Romiplostim and Eltrombopag are currently available thrombopoietin receptor agonists (TPO-RAs) that stimulate platelet production. Some studies with very small number of cases have reported their potential efficacy in the allo-SCT setting. For this reason, the aim of our study is to analyze the efficacy and safety of TPO-RAs for s…
Allogeneic Stem Cell Transplantation in Mantle Cell Lymphoma; Insights into Its Potential Role in the Era of New Immunotherapeutic and Targeted Therapies : The GETH/GELTAMO Experience
Simple Summary We present the long-term results of patients receiving allogeneic stem cell transplantation (allo-SCT) for relapsed/refractory mantle cell lymphoma (R/R MCL) in the last 25 years in Spain. We conclude that allo-SCT may be a curative option in R/R MCL with a low cumulative incidence (CI) of relapse, although non-relapse mortality (NRM) is still high, which is mainly secondary to acute graft-versus-host disease (aGVHD). Results are better for fit patients, using HLA-identical (related or unrelated) or haploidentical related donors and without previous ASCT. However, the arrival of new highly effective and low toxic immunotherapeutic or targeted therapies inevitably will relegat…
Post-transplantation cyclophosphamide after HLA identical compared to haploidentical donor transplant in acute myeloid leukemia: a study on behalf of GETH-TC
Post-transplantation cyclophosphamide (PTCY) effectively prevents graft-versus-host disease (GVHD) after unmanipulated HLA-haploidentical hematopoietic stem cell transplantation (HSCT) and achieves low rates of GVHD in HLA-identical transplantation. To compare the outcomes of haploidentical versus HLA identical HSCT in patients undergoing HSCT for acute myeloid leukemia (AML) using PTCY. We conducted a retrospective study of 229 patients undergoing first HSCT for AML using PTCY with additional immunosuppression, 99 from matched sibling or unrelated donor (MSD/MUD) performed in 3 hospitals and 130 from haploidentical donors (haplo group) performed in 20 hospitals within the Spanish Group of …
Allogeneic Hematopoietic Stem Cell Transplantation for T Cell Lymphomas: Improved Results Overtime
INTRODUCTION: Allogeneic hematopoietic stem cell transplantation (alloSCT) is the only curative strategy for relapsed/refractory T cell lymphoma (T-NHL). In the past ten years, there have been several improvements in conditioning regimens and graft versus host disease prophylaxis (GVHD), which have contributed to lower transplant-related mortality (TRM). Also, selective and low toxicity therapies, might improve response quality in some T-NHL Recently, haploidentical stem cell transplantation (Haplo) with post-transplant cyclophosphamide is a new option for those patients who do not have an HLA-identical sibling or a suitable unrelated donor, but also it has shortened the time for urgent cas…
