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...
Background : Graft versus host disease (GVHD) is among major complications of allogeneic hematopoietic stem cells transplantation, and also is an important factor affecting the outcome of transplantation. An increased incidence of GVHD has been suggested following allogeneic peripheral blood stem cells (PBSC) transplantation, however, how this affects survival is not yet well clear. In this stu...
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...
introduction: human leukocyte antigen (hla) genes are the most polymorphic loci in the human genome. they predict the outcome of transplantation by detecting self from non-self antigens. the best use of hla typing is to find a hla-match donor for bmt candidate patients. evidence suggests that matching unrelated donors and recipients for hla-a, -b and -drb1 loci is a prediction for an improved o...
چکید ه سابقه و هدف ناسازگاری HA-1 بین گیرنده و دهنده سلول‌های بنیادی خونساز با بروز GVHD حاد مطرح شده است. لذا هدف این مطالعه ارزیابی فراوانی HA-1 و پایش ارتباط بین ناسازگاری HA-1 و بروز GVHD در بیماران ایرانی دریافت کننده پیوند سلول‌های بنیادی خونساز از خواهر یا برادر با شباهت HLA-A2 بود. مواد وروش‌ها مطالعه انجام شده از نوع تحلیلی بود. DNA استخراج شده از 55 جفت گیرنده ـ دهنده HLA-A2...
