Monitoring for Tolerance to Kidney or Combined Kidney-Pancreas Transplants

2014-08-27 03:59:24 | BioPortfolio

Summary

This protocol facilitates the development of methods for determining whether transplant recipients have developed immune hyporesponsiveness or tolerance towards their allograft. These methods will involve the study of peripheral blood or biopsy tissue obtained at regular intervals from patients receiving kidney or combined kidney-pancreas allografts at the Warren G. Magnuson Clinical Center. In addition, patients that have previously received a kidney or combined kidney-pancreas allograft will be evaluated using assays requiring peripheral blood mononuclear cells and/or biopsies. Assays developed under this protocol will be used in subsequent protocols to assess the effects of immune modulating treatment regimens and may eventually be used to direct clinical care or guide the withdrawal of immunosuppressive agents. However, patients enrolled in this protocol will not have any change in treatment based solely on the assays developed without being enrolled in an additional study.

Efficacy of Topical Cyclosporine A for Treatment and Prevention of Graft Rejection in Corneal Grafts With Previous Rejection Episodes

The use of topical Cyclosporine A early after an episode of endothelial graft rejection after penetrating keratoplasty and continuing its administration for 6 months can reduce the course ...

Study to Assess LX201 for Prevention of Corneal Allograft Rejection or Graft Failure in Subjects Who Have Experienced One or More Rejection Episodes Following Penetrating Keratoplasty

This study will evaluate the use of LX201 to prevent future graft rejection episodes and/or graft failure in patients who have undergone corneal transplantation and who have recently exper...

Evaluation of an Early Screening Test of Chronic Rejection and of Operational Tolerance by MicroArray in Renal Graft (Protocol DPRC Array)

The aim of the study is to explore the possibility to identify, at an early stage after a renal graft and from blood samples collected within first months after graft, a predictive transcr...

Intentional Rejection of the Donor Graft Using Recipient Leukocyte Infusion(s) Following Nonmyeloablative Allogeneic Stem Cell Transplantation

One risk of a stem cell transplant is that the donated stem cells do not grow in the recipient. This is called graft rejection. Previous laboratory research has suggested that the reacti...

Prediction of Acute Rejection in Renal Transplant

Acute rejection is still a major risk factor affecting the prognosis of kidney transplant patients. Alloreactive cells of the recipient infiltrate the kidney graft and cause inflammatory r...

Urinary miR-155-5p and CXCL10 as prognostic and predictive biomarkers of rejection, graft outcome and treatment response in kidney transplantation.

MicroRNAs (miRNAs) may be useful biomarkers of rejection and allograft outcome in kidney transplantation. Elevated urinary CXCL10 levels have been associated with acute rejection (AR) and may predict ...

Renal PGC1α May Be Associated with Recovery after Delayed Graft Function.

Delayed renal graft function (DGF) contributes to the determination of length of hospitalization, risk of acute rejection, and graft loss. Existing tools aid the diagnosis of specific DGF etiologies s...

Reply to Hernandez et al - GWAS of acute renal graft rejection.

Hernandez et al. recently reported on several large genome-wide association studies (GWAS) in kidney transplantation(1). In particular, they investigated the effect of either donor SNPs, recipient SN...

Pancreas transplant rejection episodes are not revealed by biopsies of the donor duodenum in a prospective study with paired biopsies.

The surgical technique with duodeno- duodenal enteroanastomosis of pancreas transplants allows for representative endoscopic ultrasound guided needle biopsies of the donor duodenum and the pancreas gr...

Revisiting Chronic Rejection Following living donor liver transplantation in the Tacrolimus Era: A Single Centre Experience.

Chronic rejection (CR) is an uncommon but important cause of graft dysfunction, leading to graft loss and often requires re-transplantation. This study evaluates the incidence and outcome of patients ...

Medical and Biotech [MESH] Definitions

The immune responses of a host to a graft. A specific response is GRAFT REJECTION.

A form of ischemia-reperfusion injury occurring in the early period following transplantation. Significant pathophysiological changes in MITOCHONDRIA are the main cause of the dysfunction. It is most often seen in the transplanted lung, liver, or kidney and can lead to GRAFT REJECTION.

A general term for the complex phenomena involved in allo- and xenograft rejection by a host and graft vs host reaction. Although the reactions involved in transplantation immunology are primarily thymus-dependent phenomena of cellular immunity, humoral factors also play a part in late rejection.

An immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.

Immunological rejection of leukemia cells following bone marrow transplantation.
