HSCT from an unrelated HLA-mismatched donor (MMUD) is one of the alternatives where HLA-matched not found. The aim this study was to compare GvHD prophylaxis with anti-thymocyte globulin (ATG) vs. post-transplant cyclophosphamide (PT-Cy). Thirty-nine adult patients were uniformly treated rabbit ATG-Cy-A-MTX and peripheral blood stem cell (PBSC) 40 PT-Cy-MMF-tacrolimus PBSC. This retrospective r...

Post-transplant Cyclophosphamide (PT-Cy) has proved efficacy as GVHD prophylaxis regimen after HSCT. However, experiences are limited with controversial results. We herein, assess the of PT-Cy compared to Methotrexate regimen. Eighty patients acute leukemia received a fully matched allogeneic HSCT or Haplo-identical were analyzed. Group I (Historical group) included 40 Methotrexate, Cyclosporin...

BACKGROUND Allogenic hematopoietic stem cell transplantation (allo-SCT) is the most effective post-remission treatment for adults with high-risk acute lymphoblastic leukemia (ALL). The aim of the study was to analyze results of unmanipulated haploidentical allo-SCT (haplo-SCT) for adults with ALL and to identify prognostic factors. METHODS We performed a retrospective analysis on 208 adults t...

Intestinal graft-versus-host disease (I-GvHD) represents a life-threatening complication in allogeneic stem cell transplantation (SCT). Unfortunately, non-invasive validated diagnostic tools to diagnose I-GvHD, evaluate treatment response, and guide the duration of immunosuppression are still lacking. We employed standard ultrasound power Doppler follow up on pediatric intestinal GvHD. herein r...

Eighteen patients, twelve men and six women, with aplastic anemia underwent allogenic bone marrow transplantation (BMT) from HLA-matched siblings during the period of 1990 to 1996. The conditioning regimen was cyclophosphamide with or without busulfan, depending on the cause of aplasia. Antilymphocyte globulin (ALG) and cyclosporine were used for rejection and acute GVHD prophylaxis, respe...

background: the study attempts to assess the relationship between chimerism analysis using polymerase chain reaction of short tandem repeat (str) and the incidence of chronic graft versus host disease (gvhd) as well as survival. methods: the retrospective cohort included all patients who received allo-hsct between 2005 to 2013. data collected by day +100 were reviewed in terms of the incidence ...

Antigen-stimulated naïve T cells differentiate into effector and memory cells, of which resident (TRM) reside permanently in organ tissues. Involvement TRM has been indicated pathological conditions various skin diseases. CD122, is the β chain subunit interleukin (IL)-2 IL-15 receptors, expressed on immune including cells. To investigate whether CD122 signaling CD8+ mediates development mucocut...

Background: It is suggested that HA-1 mismatching among hematopoietic stem cell transplanted recipients-donors is associated with acute graft-versus-host disease (aGVHD). So the aim of this study was to evaluate HA-1 frequency and examine the correlation between HA-1 disparity and GVHD patients who received transplantation from a HLA-identical sibling. Samples and Methods: the DNA was extracted...

Abstract Gastrointestinal (GI) graft-versus-host disease (GVHD) is a major barrier in allogeneic hematopoietic stem cell transplantation (allo-HSCT). The metabolite retinoic acid (RA) potentiates GI-GVHD mice via alloreactive T cells expressing the RA receptor-α (RARα), but role of RA-responsive human remains undefined. Therefore, we used conventional and novel sequential immunostaining flow cy...
