Effect of sirolimus on immune reconstitution following myeloablative allogeneic stem-cell transplantation: An ancillary analysis of a randomized controlled trial comparing Tacrolimus/Sirolimus with Tacrolimus/Methotrexate (Blood and Marrow Transplant Clinical Trials Network/BMT CTN 0402).

Summary of "Effect of sirolimus on immune reconstitution following myeloablative allogeneic stem-cell transplantation: An ancillary analysis of a randomized controlled trial comparing Tacrolimus/Sirolimus with Tacrolimus/Methotrexate (Blood and Marrow Transplant Clinical Trials Network/BMT CTN 0402)."

Although allogeneic hematopoietic cell transplantation (HCT) is a potentially curative therapy for hematologic neoplasms, one of its limiting toxicities continues to be graft versus host disease, both acute and chronic (aGVHD, cGVHD). Sirolimus is a mammalian target of rapamycin (mTOR) inhibitor which has been found to be effective in GVHD prophylaxis, in combination with calcineurin inhibitors like tacrolimus. The impact of sirolimus on immune reconstitution has not been comprehensively investigated in-vivo thus far. We now present an ancillary analysis of the randomized study BMT-CTN 0402, examining the effect of sirolimus on immune subsets post-transplant. We further examine the association between different lymphocyte subsets and outcomes post-transplant in each arm.

Use of multivariate immune reconstitution patterns to describe immune reconstitution after allogeneic stem cell transplantation in children.

Immune reconstitution after hematopoietic stem cell transplantation (HSCT) is a complex process. Impacts of the reconstitution of different immune cells over time are complex and difficult to understa...

Immune recovery after in vivo T-cell depletion myeloablative conditioning hematopoietic stem cell transplantation in severe beta-thalassemia children.

The clinical outcome of HSCT in those with severe beta-thalassemia (β-TM) is closely related to post-transplantation immune reconstitution (IR). However, the data on the IR in these settings are scar...

Comparative effectiveness of busulfan/cyclophosphamide versus busulfan/fludarabine myeloablative conditioning for allogeneic hematopoietic cell transplantation in acute myeloid leukemia and myelodysplastic syndrome.

Busulfan/cyclophosphamide (Bu/Cy) and busulfan/fludarabine (Bu/Flu) are both standard myeloablative conditioning (MAC) regimens for allogeneic hematopoietic cell transplantation (alloHCT). We compared...

Impact of alemtuzumab pharmacokinetics on T-cell dynamics, graft-versus-host disease and viral reactivation in patients receiving allogeneic stem cell transplantation with an alemtuzumab-based T-cell-depleted graft.

Administration of alemtuzumab (targeting the CD52 antigen) to the patient (in-vivo) or to the graft (in-vitro) before allogeneic stem cell transplantation (alloSCT) decreases the incidence of graft-ve...

Evolutionary perspective on the hematopoietic system through a colonial chordate: allogeneic immunity and hematopoiesis.

Evolution and selection have shaped diverse immune systems throughout phylogeny, the vast majority of which remain unexplored. Botryllus schlosseri is a colonial tunicate, a sister group to vertebrate...

Non-myeloablative Allogeneic Hematopoietic Stem Cell Transplantation (NST) for Patients With Refractory Crohn's Disease

Allogeneic transplantation has been a high-risk procedure, although non-myeloablative conditioning regimens (mini-transplantation) minimizes regimen related toxicity. The investigators, th...

Study of Factors Involved in the Regulation of Immune Responses After Allogeneic Hematopoietic Stem Cell Transplantation

The study concerns donors and patients receiving allogeneic stem cell haematopoietic transplantation. The aim of the study is to analyse HSC graft content in immune effector T (naive, memo...

Medical and Biotech [MESH] Definitions

Regeneration of normal immune function after immune depleting procedures or infections (e.g., HEMATOPOIETIC STEM CELL TRANSPLANTATION). Delayed and incomplete reconstitution of the ADAPTIVE IMMUNE system in particular involving T-CELLS is associated with increase or relapse of infection.

An immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.

Agents that destroy bone marrow activity. They are used to prepare patients for BONE MARROW TRANSPLANTATION or STEM CELL TRANSPLANTATION.

Exuberant inflammatory response towards previously undiagnosed or incubating opportunistic pathogens. It is frequently seen in AIDS patients following HAART.

A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
