Patients with end-stage kidney disease (ESKD) comprise a vulnerable population to infections. COVID-19 has been responsible for high mortality worldwide. To-date, there is limited data regarding the impact of COVID-19 in the ESKD population. We report clinical outcomes of ESKD patients with COVID-19 admitted to an academic hospital in New Orleans.


We conducted an observational study in patients with ESKD and COVID-19 hospitalized at Ochsner Medical Center over a 7-week period. We compared rates of need for mechanical ventilation, shock, need for intensive care (ICU) and in-hospital mortality as outcome measures between patients with and without ESKD.


Among 851 admissions (67% black) with COVID-19, 49 (6%) patients had diagnosis of ESKD. Patients with ESKD were mostly male [61% vs 49% in non-ESKD (n = 806), p = 0.10] with a median age of 64 (38 – 90) years. Median body mass index (BMI) were 32 vs 27 kg/m2 (p = 0.11) for those admitted to ICU vs wards, respectively. Thirteen of them (27%) vs 293 (37%) in the non-ESKD group, p=0.16) were admitted to an intensive care unit (ICU). In-hospital mortality rate for the ESKD cohort was 32% compared to 24% for non-ESKD (p = 0.21). Compared to a subset with 161 patients with acute kidney injury (AKI) with 50% mortality, the 32% mortality rate in ESKD was significantly lower (p = 0.027). Shock and/or mechanical ventilation requirement were comparable between groups [12 (24%) of those with ESKD vs 213 (26%) of non-ESKD, p = 0.65]. Median serum ferritin level was significantly more elevated in ESKD compared to non-ESKD [2125 vs 633 ng/mL, p = 0.0019).


Clinical outcomes in individuals with ESKD with COVID19 appear to be grossly similar to that of non-ESKD population with COVID19. The similar mortality rate was seen despite higher levels of ferritin, suggesting that the interpretation of the significance of serum ferritin in ESKD has to be done with caution. Furthermore, the mortality in ESKD patients with COVID19 is lower than that observed in AKI. The observed lack of increased mortality in ESKD does not align with the outcomes of this patient population in other critical illnesses. The ability to mount and exaggerated inflammatory response in COVID19 might be somewhat restricted in ESKD.
