Renal transplantation is a most valuable treatment for patients with end-stage renal disease as it offers improved survival and quality-of-life benefits compared with dialysis (Evans, Manninen et al. 1985; Port, Wolfe et al. 1993). However, there has been no satisfactory increase in long-term graft survival despite significant advances in the field of renal transplantation (Meier-Kriesche, Scho...

Immunoperoxidase staining was carried out using monoclonal antibody against endothelin-1 on renal allograft biopsy specimens from thirty one patients with acute renal transplant rejection: Banff 97 score IA (n = 11), score IB (n = 10) and score IIA (n = 10). As a control 10 biopsy specimens of the kidneys removed because of trauma were used. Endothelin-1 immunostaining was investigated in the r...

The incidence of acute rejection of the kidney allograft in the world has been around 15% during the period between 2001 and 2003. It is clinically defined as an elevation in the level of serum creatinine by more than 0.3 mg/dL and is diagnosed by kidney biopsy. On pathologic examination, the interstitium of the allograft is diffusely edematous and infiltrated by CD4 and CD8 lymphocytes. Tubuli...

After liver transplantation, a relatively low intensity immunosuppressive regimen is employed in our unit: after initial triple therapy (prednisolone, azathioprine, cyclosporin), prednisolone is discontinued at three months and azathioprine at one year. A retrospective study was therefore performed to determine the incidence of rejection, and to identify risk factors for rejection in our patien...

The aim of this study was to investigate the effect of cyclosporine A (CsA) and tacrolimus (FK506) on interleukin-15 (IL-15) production during acute rejection following heart transplantation in mice. Inbred male Balb/c (H‑2d) and C57BL/6 (H-2b) mice were used to establish a heterotopic intra-abdominal cardiac transplantation model. The mice were divided in four groups: syngeneic control, alloge...

background: calcineurin inhibitors (cni) have significantly reduced the incidence of acute rejection. nephrotoxicity however may contribute to long-term allograft dysfunction. mycophenolate mofetil (mmf) may allow cyclosporine (csa) dose reduction without increasing the risk of rejection. methods: in seventy-eight living unrelated kidney transplant patients with renal dysfunction, we studied th...

In order to evaluate the role of anti-endothelial cell antibody (AECA) in acute rejection in renal transplantation, serum AECA IgG titers were measured in 68 healthy controls, 111 chronic hemodialysis (HD) patients and 58 first renal transplant recipients. The AECA titer in hemodialysis patients was higher than in healthy controls (13.9 +/- 5.0 vs. 4.8 +/- 2.3 U/mL, p < 0.01). In transplant rec...

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, respective...

BACKGROUND Acute rejection episodes are a major determinant of renal allograft survival, and the improvement of the transplantation results in the last two decades is largely due to a progressive decrease in the incidence of acute rejection. These results are explained by the incorporation of new immunosuppressive agents since the introduction of cyclosporine. Because the detrimental effect of ...
