Prior studies of sex differences in kidney graft survival showed conflicting results. We hypothesized that the association between recipient and failure risk differs by age donor sex. evaluated 159,417 patients recorded Scientific Registry Transplant Recipients database who received a first deceased-donor transplant (1995-2013). used time-varying Cox models to estimate death-censored failure. Models, stratified on adjusted for potential confounders, included current interaction term. Among...

Cardiovascular mortality is the leading cause of death in ESRD. Whereas innate and adaptive immunity have established roles cardiovascular disease, role humoral unknown. We conducted a retrospective cohort study first-time adult kidney transplant candidates (N=161,308) using data from Scientific Registry Transplant Recipients Centers for Medicare Medicaid Services to evaluate whether anti-human leukocyte antigen antibodies, measured as panel reactive antibodies (PRAs), are related...

Solid organ transplant (SOT) recipients are at high risk for complications from coronavirus disease 2019 (COVID-19). Vaccination may mitigate this risk; however, immunogenicity appears to be significantly impaired, with reports of increased breakthrough infection. It is unknown if vaccine infections milder or as severe in unvaccinated patients.

<h3>Background:</h3> Severe COVID-19 appears to disproportionately affect people who are immunocompromised, although Canadian data in this context limited. We sought determine factors associated with severe outcomes among recipients of organ transplants across Canada. <h3>Methods:</h3> performed a multicentre, prospective cohort study all solid from 9 transplant programs Canada received diagnosis March 2020 November 2021. Data were analyzed risk for oxygen requirement and other metrics...

The aim of this study was to determine how the Banff antibody-mediated rejection (ABMR) classification for kidney transplantation is interpreted in practice and affects therapy. Antibody-Mediated Injury Workgroup electronically surveyed clinicians pathologists worldwide regarding diagnosis treatment 6 case-based scenarios. participants' (95 72 renal pathologists) assigned diagnoses were compared intended (reference standard). reference standard differed by 26.1% (SD 28.1%) 34.5% 23.3%)...

To mitigate risks related to human leukocyte antigen (HLA) incompatibility, we assessed whether certain structurally defined HLA targets present in donors but absent from recipients, known as eplet mismatches (EMM), are associated with death-censored graft failure (DCGF).We studied a cohort of 118,313 American 0% panel reactive antibodies (PRA) first kidney transplant recipients (2000 2015) the Scientific Registry Transplant Recipients. Imputed allele-level donor and recipient HLA-A, -B, -C,...

ABSTRACT Introduction The diagnosis of antibody‐mediated rejection (AMR) requires input from several transplant professionals. Bringing clinical and laboratory experts together may help standardize care. Yet, little is known about current global practices multidisciplinary meetings for AMR management. Methods Banff Antibody‐Mediated Injury Working Group approached professional societies worldwide to distribute a survey on the availability, content, participants, perceived value, barriers...
