Abstract

Item does not contain fulltext, The Eurotransplant Senior Program (ESP) has expedited the chance for elderly patients with kidney failure to receive a timely transplant. This current study evaluated survival parameters of kidneys donated after brain death with or without matching for HLA-DR antigens. This cohort study evaluated the period within ESP with paired allocation of 675 kidneys from donors 65 years and older to transplant candidates 65 years and older, the first kidney to 341 patients within the Eurotransplant Senior DR-compatible Program and 334 contralateral kidneys without (ESP) HLA-DR antigen matching. We used Kaplan-Meier estimates and competing risk analysis to assess all cause mortality and kidney graft failure, respectively. The log-rank test and Cox proportional hazards regression were used for comparisons. Within ESP, matching for HLA-DR antigens was associated with a significantly lower five-year risk of mortality (hazard ratio 0.71; 95% confidence interval 0.53-0.95) and significantly lower cause-specific hazards for kidney graft failure and return to dialysis at one year (0.55; 0.35-0.87) and five years (0.73; 0.53-0.99) post-transplant. Allocation based on HLA-DR matching resulted in longer cold ischemia (mean difference 1.00 hours; 95% confidence interval: 0.32-1.68) and kidney offers with a significantly shorter median dialysis vintage of 2.4 versus 4.1 yrs. in ESP without matching. Thus, our allocation based on HLA-DR matching improved five-year patient and kidney allograft survival. Hence, our paired allocation study suggests a superior outcome of HLA-DR matching in the context of old-for-old kidney transplantation.

Abstract

Background Coronavirus disease 2019 (COVID-19)-related short-term mortality is high in dialysis patients, but longer-term outcomes are largely unknown. We therefore assessed patient recovery in a large cohort of dialysis patients 3 months after their COVID-19 diagnosis. Methods We analyzed data on dialysis patients diagnosed with COVID-19 from 1 February 2020 to 31 March 2021 from the European Renal Association COVID-19 Database (ERACODA). The outcomes studied were patient survival, residence and functional and mental health status (estimated by their treating physician) 3 months after COVID-19 diagnosis. Complete follow-up data were available for 854 surviving patients. Patient characteristics associated with recovery were analyzed using logistic regression. Results In 2449 hemodialysis patients (mean ± SD age 67.5 ± 14.4 years, 62% male), survival probabilities at 3 months after COVID-19 diagnosis were 90% for nonhospitalized patients (n = 1087), 73% for patients admitted to the hospital but not to an intensive care unit (ICU) (n = 1165) and 40% for those admitted to an ICU (n = 197). Patient survival hardly decreased between 28 days and 3 months after COVID-19 diagnosis. At 3 months, 87% functioned at their pre-existent functional and 94% at their pre-existent mental level. Only few of the surviving patients were still admitted to the hospital (0.8–6.3%) or a nursing home (∼5%). A higher age and frailty score at presentation and ICU admission were associated with worse functional outcome. Conclusions Mortality between 28 days and 3 months after COVID-19 diagnosis was low and the majority of patients who survived COVID-19 recovered to their pre-existent functional and mental health level at 3 months after diagnosis.

Abstract

Background Patients on kidney replacement therapy (KRT) are at very high risk of coronavirus disease 2019 (COVID-19). The triage pathway for KRT patients presenting to hospitals with varying severity of COVID-19 illness remains ill-defined. We studied the clinical characteristics of patients at initial and subsequent hospital presentations and the impact on patient outcomes. Methods The European Renal Association COVID-19 Database (ERACODA) was analysed for clinical and laboratory features of 1423 KRT patients with COVID-19 either hospitalized or non-hospitalized at initial triage and those re-presenting a second time. Predictors of outcomes (hospitalization, 28-day mortality) were then determined for all those not hospitalized at initial triage. Results Among 1423 KRT patients with COVID-19 [haemodialysis (HD), n = 1017; transplant, n = 406), 25% (n = 355) were not hospitalized at first presentation due to mild illness (30% HD, 13% transplant). Of the non-hospitalized patients, only 10% (n = 36) re-presented a second time, with a 5-day median interval between the two presentations (interquartile range 2–7 days). Patients who re-presented had worsening respiratory symptoms, a decrease in oxygen saturation (97% versus 90%) and an increase in C-reactive protein (26 versus 73 mg/L) and were older (72 vs 63 years) compared with those who did not return a second time. The 28-day mortality between early admission (at first presentation) and deferred admission (at second presentation) was not significantly different (29% versus 25%; P = 0.6). Older age, prior smoking history, higher clinical frailty score and self-reported shortness of breath at first presentation were identified as risk predictors of mortality when re-presenting after discharge at initial triage. Conclusions This study provides evidence that KRT patients with COVID-19 and mild illness can be managed effectively with supported outpatient care and with vigilance of respiratory symptoms, especially in those with risk factors for poor outcomes. Our findings support a risk-stratified clinical approach to admissions and discharges of KRT patients presenting with COVID-19 to aid clinical triage and optimize resource utilization during the ongoing pandemic.

31. Beneficial Effects of High S100A9 Expression On Graft Infiltrating Myeloid Cells in Kidney Transplantation

Abstract

Our goal is to predict the impact of acute rejection (AR) on kidney graft outcome using molecular markers. In patients suffering from AR (n=28) we initially identified by microarray S100A9 expression as a prognostic indicator of graft outcome. In a second cohort, we confirmed that patients with high S100A9 expression during AR (n=36) have significantly better 12-year graft survival (91.5%) than low expressers (n=61; 69.2%). Next, we studied the mechanism by which S100A9 exerts its biologic effects. In the biopsies, the S100A9+ cell population consisted of CD68+ myeloid cells of which 75% expressed HLA-DR. A minor fraction of S100A9+ cells represented CD66b+ granulocytes. S100A9 levels were related to expression of immune regulatory molecules IL-10, FoxP3/CD3, and p40 component of the reactive oxygen species (ROS)-producing machinery. Overexpression (10-35 fold) of S100A9 in cultured macrophages led to a dose-dependent increase in ROS production, whereas S100A9 inhibition by siRNA transfection resulted into decreased ROS production. The presence of low concentrations of the ROS metabolite H2O2 for 0.5h led to a significant downregulation of the proliferative response of activated T cells. S100A9 levels in the graft are specifically elevated during conditions of increased inflammation. The presence of distinct myeloid cell subsets early after transplantation provides prognostic information with respect to graft survival. The data suggest that an increased expression of S100A9 by myeloid cells leads to local ROS production in the immune synapse, and as a consequence, to downregulation of the alloimmune responses by T cells to the graft.

Abstract

Kidney transplant donors are not currently implicated in predicting BKpolyomavirus (BKPyV) infection in kidney transplant recipients. It has been postulated, however, that BKPyVinfection originates from the kidney allograft. Because BKPyVseroreactivity correlates with BKPyVreplication and thus might mirror the infectious load, we investigated whether BKPyVseroreactivity of the donor predicts viremia and BKPyV‐associated nephropathy (BKPyVAN) in the recipient. In a retrospective cohort of 407 living kidney donor–recipient pairs, pretransplantation donor and recipient sera were tested for BKPyVIgG levels and correlated with the occurrence of recipient BKPyVviremia and BKPyVANwithin 1 year after transplantation. Donor BKPyVIgG level was strongly associated with BKPyVviremia and BKPyVAN(p < 0.001), whereas recipient BKPyVseroreactivity showed a nonsignificant inverse trend. Pairing of high–BKPyV‐seroreactive donors with low‐seroreactive recipients resulted in a 10‐fold increased risk of BKPyVviremia (hazard ratio 10.1, 95% CI3.5–29.0, p < 0.001). In multivariate analysis, donor BKPyVseroreactivity was the strongest pretransplantation factor associated with viremia (p < 0.001) and BKPyVAN(p = 0.007). The proportional relationship between donor BKPyVseroreactivity and recipient infection suggests that donor BKPyVseroreactivity reflects the infectious load of the kidney allograft and calls for the use of pretransplantation BKPyVserological testing of (potential) donors and recipients. In this retrospective cohort study, the authors find pretransplantation donor–recipient pair BK polyomavirus seroreactivity predicts viremia and nephropathy after kidney transplantation.
