Utility of the ELISPOT Assay for Monitoring BK Polyomavirus Immune Response in Kidney Transplant Recipients: A Systematic Review and Meta-Analysis
Year: 2024
Type: review
Abstract: The study emphasizes the role of the Enzyme-Linked Immunosorbent Spot (ELISPOT) assay in assessing the immune response against BK virus (BKV) infection after kidney transplantation. This is crucial because BKV infection can lead to BKV nephropathy (BKVAN), which can result in graft dysfunction and potential allograft loss. The ELISPOT assay helps evaluate the recipient’s immune response by detecting interferon-gamma (IFN-γ) production in response to BKV. According to the systematic review and meta-analysis, ELISPOT has shown a high sensitivity (0.95) and specificity (0.88), indicating its strong potential as a tool for identifying patients at risk of active BKV infection. In particular, patients with negative ELISPOT results had a significantly higher risk of active BKV replication (odds ratio of 71.9), and there was a clear distinction between active and resolv-ing BKV infections based on the number of IFN-γ producing cells. Thus, integrating the ELISPOT assay with viral load monitoring could help tailor immunosuppressive therapy, balancing the need to prevent transplant rejection while managing the risk of BKV replication. This dual approach could potentially improve patient outcomes by providing a more precise strategy for managing BKV infection in kidney transplant recipients.
