1. Concomitant Renal and Urinary Bladder Allograft Transplantation

   Rochester, Minn.

   Patients that need reconstruction or re-building of their urinary bladder are often limited to having a segment of their intestine used for that purpose. Using intestine is less than ideal as it is an absorptive, mucous producing tissue and placing this in constant contact with urine creates significant long term problems. In patients that require a kidney transplant and bladder reconstruction, this study seeks to use a bladder graft from a deceased donor rather than intestine.

2. A Study of Study of Immune Tolerance Mechanisms in Kidney Transplant Patients

   Scottsdale/Phoenix, Ariz.

   Hypothesis: we hypothesize that the abundance and functions of Breg subsets in kidney transplant patients could be associated with transplant tolerance and rejection, including DSA-mediated kidney transplant rejection. In addition, oral corticosteroid treatment significantly alters the frequency and function of Breg subsets, which could lead altered clinical outcomes.
   
   Aims, purpose, or objectives:
   1. Investigate the frequency Bregs and their ability to express IL-10 along with other immune cells in the context of tolerance/rejection in kidney transplant patients.
   we hypothesize that the abundance and functions of Breg subsets in kidney transplant patients could be associated with transplant tolerance and rejection, including DSA-mediated kidney transplant rejection.
   
   2.Investigate the frequency and functions of Bregs along with other immune cells in the setting of long term corticosteroid use.
   We hypothesize that oral corticosteroid treatment significantly alters the frequency and function of Breg subsets, which could lead altered clinical outcomes.

3. A Study to Evaluate Alloantibody Titer in Highly Sensitized Kidney Transplant Candidates

   Jacksonville, Fla., Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate the utility of using anti-HLA antibody titer to measure the effectiveness of antibody lowering therapy (i.e., desensitization) in highly-sensitized kidney transplant candidates.

    

4. A Study to Assess Reproductive History in Kidney Donors

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to analyze the effect of parity, menopause and reproductive lifespan on kidney structure and function.

5. Tissue and Blood Registry for Individuals with Liver and Biliary Tumors

   Jacksonville, Fla.

   This study will collect and store samples of tissue and blood for current and future research studies on Liver and Biliary Tumors.

6. Ultrasound Microvessel Imaging of Transplant Kidney

   Rochester, Minn.

   The purpose of this study is to investigate the value of ultrasound microvessel imaging for evaluation of transplant kidney health.

7. Paired Marrow Aspirations to Assess Assays in Sensitized Renal Allograft Recipients

   Rochester, Minn.

   The aim of this study is to determine the validity of two tests on bone marrow of sensitized kidney transplant recipients in order to better understand why these patients with antibodies against their donors are at a greater risk of rejection of their transplanted organs.

8. A Study of Immune Cell Abnormalities Found in Individual Patients who have Type 1 Diabetes and are Waiting for Pancreas or Pancreas/Kidney Transplant Surgery

   Rochester, Minn.

   The purpose of this study is to measure and characterize specific immune cell abnormalities found in patients who have type 1 diabetes and may or may not be on the waiting list for either a pancreas alone or a pancreas and kidney transplant.

9. APOL1 Long-term Kidney Transplantation Outcomes Network (APOLLO)

   Rochester, Minn.

   The purpose of this study is to attempt to improve outcomes after kidney transplantation and to improve the safety of living kidney donation based upon variation in the apolipoprotein L1 gene (APOL1). Genes control what is inherited from a family, such as eye color or blood type. Variation in APOL1 can cause kidney disease. African Americans, Afro-Caribbeans, Hispanic Blacks, and Africans are more likely to have the APOL1 gene variants that cause kidney disease. APOLLO will test DNA from kidney donors and recipients of kidney transplants for APOL1 to determine effects on kidney transplant-related outcomes.

10. Lost Wages Support for Living Organ Donors Demonstration Project

    Scottsdale/Phoenix, Ariz.

    The purpose of this study will be to evaluate the effect of the US Health Resources and Services Administration (HRSA) program to reimburse lost wages on the decision of individuals to initiate evaluation for living organ donation.
