Background: Bone Marrow Transplantation is one of the most important therapeutic methods in much malignant and nonmalignant disease. Patients with Bone Marrow Transplantation (BMT) following radiotherapy and chemotherapy will suffer from immuno-suppression. Therefore they are susceptible to get saprophytic fungi infection that sometimes are killer. Materials and Methods: The purpose of this ...
Interactions between killer immunoglobulin-like receptors (KIRs) and human leukocyte antigen (HLA) class I ligands influence development of natural killer (NK) cell repertoire and response to infection, cancer, and allogeneic tissue. As KIRs and HLA class I molecules are highly polymorphic, clinical allogeneic hematopoietic cell transplantation is predicted to frequently involve KIR mismatch, a...
BACKGROUND AND OBJECTIVES The role of CD4+CD25+ T regulatory cells (Tregs) in immune tolerance in experimental transplantation is very important but the clinical significance of circulating Tregs in the peripheral blood is undetermined. We evaluated the association between the frequency of T cell activation markers CD25 and CD71 and clinical parameters that may affect the level of these T cell ...
Background: Long term use of immunosuppressive therapy in transplant recipients in order to prevent acute and chronic rejection increases the long term risk of cancer. This study evaluates the incidence of different organs’ cancer after renal transplantation and immunosuppressive therapy. Methods: This is a retrospective analysis of malignant tumors in renal graft recipients with more than...
Baekgrouund & purpose: In recent years, the role of adenoviruses in infection and disease in recipients of bone marrow transplantation (BMT) has been studied. It suppose that adenoviral infections are prevalant in these patients Due to using medicines for preventing transplant rejection. This study was performed to compare the incidence of adenoviruses in urine samples taken before and after...
patients and methods five hundred and sixteen serum samples of the patients undergoing hemodialysis and kidney transplantation from various cities of khuzestan province were collected. anti-hepatitis g e2 antibodies were investigated by elisa method. rnas were extracted from serums and hepatitis g rna was detected by rt-pcr. results of the 516 samples, 38 (7.36%) specimens were positive for ant...
Background: The COVID-19 pandemic has caused changes in daily life, disruption of hospital performance and medical services, especially in the organ transplant department. Objective: This study was conducted to compare the number and frequency of organ donation and transplantation in the period before and after the outbreak of the covid-19 pandemic in the transplant center of northern Iran. M...
D ESPITE genetic differences in the prevalence of blood groups and HLA antigens between the various races, the effect of the race of the donor and that of the recipient on outcome in clinical liver transplantation have never been investigated. The aims of the present study were to determine: 1. The proportion of organs contributed to the liver transplantation program at the University of Pittsb...
The CD4(+)CD25(+) T regulatory cells (Tregs) play an important role in immune tolerance in experimental transplantation but the clinical significance of circulating Tregs in the peripheral blood is undetermined. In 50 kidney transplant (KT) recipients, 29 healthy controls and 32 liver transplant (LT) recipients, the frequency of Tregs was measured with flow cytometry before and after transplant...
Background: In addition to Human Leukocyte Antigens (HLA) compatibility, gene polymorphisms in cytokines might also be important in the quality of allogeneic immune response. Objective: To evaluate the influence of HLA-DR matching and a number of cytokine gene polymorphisms on acute rejection after living-unrelated donor (LURD) kidney transplantation. Methods: A total of 42 renal transplants pe...
