Background: Presensitized patients with circulating donor-specific antibodies (DSAs) before transplantation are at risk for antibody-mediated rejection (AMR). Peritransplant desensitization mitigates but does not eliminate the alloimmune response. We examined the possibility that subthreshold AMR activity undetected by histology could be operating in some early biopsies.

Methods: This single-center, retrospective cohort study included 388 donors referred between June 2021 and December 2022.
Measuring T cell response can add information about antivirus immunity provided by antibody test results. The study evaluates the impact of a third mRNA COVID-19 vaccine dose on T cell response and antibody production in kidney transplant recipients (25 KTRs) versus healthy controls (26 Hc). Results show a significant rise in S-activated CD4+CD154+IFN?+TNF?+ double producer cells in both KTRs (p=0.

- Many kidney transplant patients are classified as having no rejection after biopsy, but some may actually have undetected rejection activities.
- A study of over 5,000 biopsies found that more than half were marked as no rejection, yet many showed signs of subthreshold T cell-mediated rejection (TCMR) and antibody-mediated rejection (ABMR).
- Patients with these hidden rejection activities are at increased risk of future graft issues, as higher levels of TCMR and ABMR correlate with worse kidney function and higher chances of rejection in subsequent biopsies.
