[Coronavirus disease 2019 pandemic from a nephrological perspective]. / "Coronavirus-disease-2019"-Pandemie aus nephrologischer Perspektive.

ABSTRACT

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has also resulted in substantial challenges for nephrology worldwide. Patients with chronic kidney diseases are a particularly vulnerable patient group in this context and in severe courses of COVID-19 the kidneys are most frequently affected by organ failure after the lungs. MATERIAL AND METHODS: In order to reliably evaluate the prevalence and mortality of dialysis patients in Germany with respect to COVID-19, during the first wave in spring 2020 the German Society of Nephrology implemented a registry for dialysis patients. Weekly data on the number and course of dialysis patients affected by COVID-19 were recorded and analyzed. RESULTS: The prevalence of COVID-19 in dialysis patients in Germany developed in two waves, similar to the course of the pandemic in the general population. In spring the prevalence in dialysis patients reached 1.4% and considerably declined during the summer. In December during the second wave of the pandemic the prevalence again rose to 1.9%, despite comprehensively implemented hygiene measures in dialysis centers. Similar to other industrial nations, dialysis patients in Germany also showed a very high lethality of COVID-19 of up to 20%. CONCLUSION: Immediate consequences for hygiene measures in dialysis institutions as well as vaccination strategies and vaccination prioritization for this patient group and the personnel treating them can be derived from the high mortality in dialysis patients. A consequence of the frequent involvement of the kidneys during infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients who had not previously suffered from advanced kidney disease should be the consistent nephrological aftercare.
