Genomics of Kidney Transplantation
Panoramica dello studio

Descrizione dettagliata
In the past, the major problems in kidney transplantation were surgical complications, acute rejection, and infections. Right now, researchers are focusing on improving immune suppression therapy and achieving better long-term survival of kidney transplants. One of the ways to try to understand what causes loss of function after many years is to find out if there is a genetic factor involved.
There are a number of differences in specific genes that have been identified and are thought to affect transplant outcomes. Studying these gene variations (differences between people or differences between populations) is important in determining whether these variations are related to transplant outcomes and how this information can help patients achieve better long-term transplant survival.

Come è strutturato lo studio?
Dettagli di progettazione
Coorti e interventi
Gruppo / Coorte |
|---|
|
Transplant Recipients Cohort
Main Study Cohort: Kidney (or kidney-pancreas) transplant recipients.
Enrollment for this cohort is closed.
|
|
Transplant Donors Cohort
Main Study Cohort: The kidney donor for transplant recipients in this study.
Enrollment for this cohort is closed.
|
|
Activity&mRNA Expression Substudy Cohort
A subset of subjects enrolled in the main study who will receive tacrolimus, cyclosporine or mycophenolate as part of maintenance immunosuppression therapy.
This group has a prospective observational cohort design.
Enrollment into the Activity and messenger ribonucleic acid (mRNA) Expression Cohort, occurring concurrently with enrollment of the rest of the study, will continue until either the required sample size of 600 is achieved or the protocol team terminates enrollment.
Participants in the Activity and mRNA Expression Cohort have additional blood draws up to 2 weeks prior to transplant, at week 1, Month 3 and Month 6 post-transplant.
