Assessing immune profiles in kidney transplant recipients and donors

Paired Bone Marrow Aspirations to Assess the Variability of Allo-ELISPOT and Allo-Specificities Assays in Sensitized Renal Allograft Recipients

Not applicable Interventional Mayo Clinic · NCT01150487

This study is trying to understand the immune system of kidney transplant patients and their donors by looking at their immune cells to see how they respond to the transplant.

What this trial studies

This study aims to evaluate the immune cell compositions in the bone marrow and lymph nodes of kidney transplant recipients and their donors. It involves paired marrow aspirations to assess various immune assays, including the AlloELISPOT and Allospecificities assays, which measure donor-specific alloantibody production. The research focuses on characterizing plasma cells and their functions, as well as analyzing T and B-cell diversity using advanced techniques like flow cytometry and mass spectrometry. The goal is to validate these assays to improve the understanding of immune responses in transplant patients.

Who should consider this trial

Good fit: Ideal candidates include pre or post renal transplant recipients and renal transplant donors who can provide informed consent.

Not a fit: Patients currently on systemic anticoagulation therapy or with certain blood count abnormalities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for managing immune responses in kidney transplant recipients, potentially enhancing transplant outcomes.

How similar studies have performed: Other studies have shown promise in assessing immune profiles in transplant populations, but this specific approach is novel in its comprehensive assessment of plasma cells and immune assays.
