Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Candidates for a kidney or combined kidney-pancreas transplant performed at the National Institutes of Health, or non-uremic healthy volunteers who are not on immunosuppressive medications.

Previous recipients of kidney or combined kidney-pancreas transplants.

Recipients of kidney or combined kidney-pancreas transplants interested in participation in the Recurrent Disease Allograft Registry.

Willingness and legal ability to give informed consent or permission from a legal guardian.

Willingness to travel to the Clinical Center for protocol specific samples to be taken, or in some cases, the ability to send samples via overnight mail.

For transplant patients, availability of donor tissue for testing. This could include splenic or peripheral blood lymphocytes from a cadaveric donor or a willing living donor enrolled on the Clinical Center Living Donor Protocol who consents to periodic phlebotomy for peripheral blood lymphocyte isolation.

Exclusion Criteria

Inability or unwillingness to comply with protocol monitoring and therapy, including, among others, a history of noncompliance, circumstances where compliance with protocol requirements is not feasible due to living conditions, travel restrictions, access to urgent medical services, or access to anti-rejection drugs after the research protocol is completed.

Any active malignancy. Patients with primary, cutaneous basal cell or squamous cell cancers may be enrolled providing these are appropriately eliminated prior to transplant.

Significant coagulopathy or requirement for anticoagulation therapy that would contraindicate protocol allograft biopsies.

Platelet count less than 100,000/mm(3).
