Background. Patients on kidney replacement therapy comprise a vulnerable population and may be at increased risk of death from coronavirus disease 2019 (COVID-19). Currently, only limited data are available on outcomes in this patient population. Methods. We set up the ERACODA (European Renal Association COVID-19 Database) database, which is specifically designed to prospectively collect detailed data on kidney transplant and dialysis patients with COVID-19. For this analysis, patients were included who presented between 1 February and 1 May 2020 and had complete information available on the primary outcome parameter, 28-day mortality. Results. Of the 1073 patients enrolled, 305 (28%) were kidney transplant and 768 (72%) dialysis patients with a mean age of 60 ± 13 and 67 ± 14 years, respectively. The 28-day probability of death was 21.3% [95% confidence interval (95% CI) 14.3–30.2%] in kidney transplant and 25.0% (95% CI 20.2–30.0%) in dialysis patients. Mortality was primarily associated with advanced age in kidney transplant patients, and with age and frailty in dialysis patients. After adjusting for sex, age and frailty, in-hospital mortality did not significantly differ between transplant and dialysis patients [hazard ratio (HR) 0.81, 95% CI 0.59–1.10, P = 0.18]. In the subset of dialysis patients who were a candidate for transplantation (n = 148), 8 patients died within 28 days, as compared with 7 deaths in 23 patients who underwent a kidney transplantation <1 year before presentation (HR adjusted for sex, age and frailty 0.20, 95% CI 0.07–0.56, P < 0.01). Conclusions. The 28-day case-fatality rate is high in patients on kidney replacement therapy with COVID-19 and is primarily driven by the risk factors age and frailty. Furthermore, in the first year after kidney transplantation, patients may be at increased risk of COVID-19-related mortality as compared with dialysis patients on the waiting list for transplantation. This information is important in guiding clinical decision-making, and for informing the public and healthcare authorities on the COVID-19-related mortality risk in kidney transplant and dialysis patients.

Steroids have been included in most immunosuppressive regimens after renal transplantation, but are feared for their side-effects. We conducted a prospective multicenter study to investigate whether it is feasible to withdraw steroids early after transplantation with the use of anti-IL-2Ra induction, tacrolimus and mycophenolate mofetil (MMF). A total of 364 patients were randomized to receive either two doses of daclizumab (1 mg/kg) and, for the first 3 days, 100 mg of prednisolone (daclizumab group n = = 186), or steroids (tapered to 0 mg at week 16; controls n = = 178). All patients received tacrolimus and MMF. The incidence of biopsy-confirmed acute rejection at 12 months was not different between the daclizumab group (15%) and the controls (14%) (95% confidence interval of difference: −6 to + + 8%, NS). Graft survival at 12 months was comparable in the two groups (daclizumab group: 91%; controls: 90%). Mean arterial blood pressure, serum lipids, and incidence of patients with hyperglycemia were temporary lower in the daclizumab group compared with controls. The immunosuppressive regimen of the daclizumab group was associated with increased costs. In conclusion, with the use of anti-IL-2Ra induction and daily therapy with tacrolimus and MMF it is feasible to withdraw steroids at 3 days after renal transplantation.
