Background: Monitoring of phenotypic characteristics of T-lymphocytes in peripheral blood is commonly performed to give the clinical parameters in the management of kidney transplant recipients. Objective: To predict rejection in renal transplantation by immune parameters. Methods: 16 non-diabetic kidney transplant candidates (4 females and 12 males, age = 20-65 yr, first time transplant) wer...
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 studi...
there are limited clinical investigations identifying the percentage of t helper 1 (th1) and t regulatory (treg) cells in stable as well as rejected kidney allografts, a concept which needs to be more studied. the aim of our study was to compare the percentage of cd4+ ifn-γ+ cells, the number of ifn-γ secreting cells and the amount of foxp3 expression in patients with or without stable graft fu...
OBJECTIVES The immunologic status of kidney allograft recipients affects transplant outcome. High levels of pretransplant serum soluble CD30 correlate with an increased risk of acute rejection. Studies show conflicting results. We evaluated the relation between pretransplant serum sCD30 levels with the risk of posttransplant acute kidney rejection in renal transplant recipients. MATERIALS AND...
Background Despite being the leading cause of graft failure, there is a lack of published data about the rates of rejection in kidney transplant patients with glomerulonephritis as the cause of end-stage renal disease. Methods We examined all consecutive adult (>18 years) renal transplant recipients with biopsy-proven native renal glomerular disease who underwent kidney transplant between 199...
BACKGROUND The standard test for the diagnosis of acute rejection in kidney transplants is the renal biopsy. Noninvasive tests would be preferable. METHODS We prospectively collected 4300 urine specimens from 485 kidney-graft recipients from day 3 through month 12 after transplantation. Messenger RNA (mRNA) levels were measured in urinary cells and correlated with allograft-rejection status w...
INTRODUCTION Due to its immunosuppressive properties, local graft irradiation (LGI) has been proposed as a second line therapy for treatment of acute kidney rejection. CASE PRESENTATION In this case-series we report 6 patients with biopsy proven acute kidney allograft rejection refractory to conventional antirejection therapy who underwent LGI for treatment of acute rejection at our center. T...
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...
Rejection is still a major obstacle in long-term allograft survival of renal transplant recipients. Long non‑coding RNAs (lncRNAs) are an important class of pervasive RNAs involved in a variety of biological functions, and which are often found to be differentially expressed between healthy and pathological conditions. The aim of this study was to compare the expression profiles of lncRNAs betw...
Acute rejection is the most common reason of graft failure after kidney transplantation and early detection is crucial to survive the transplanted kidney function. In this paper, we introduce a new approach for the automatic classification of normal and acute rejection transplants from Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI). The proposed algorithm consists of three main ...
