The Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is a newly identified virus that is spreading rapidly throughout the world and results in a severe Coronavirus-associated disease (COVID-19) in a considerable number of individuals affected. In the current pandemic, medical information on COVID-19 in high-risk patients, such as individuals with chronic kidney disease, hemodialysis and kidney transplant patients, is still scarce. Additionally, the impact of SARS-CoV2 infection on the kidney itself leading to acute kidney injury remains unclear. To overcome this lack of knowledge, the website Kidney in COVID-19 was set up using the platform kidneyinfection.org. Kidney in COVID-19 aims to provide the latest research concerning the interaction between kidney disease and the current SARS-CoV-2 pandemic for nephrologists. You are cordially invited to participate and email us latest reseach concerning the kidney in COVID-19 as well as your experiences as experts in the field so we can share expertise and knowledge.


The novel Kidney in COVID-19 Registry, which facilitates anonymous documentation of nephrology patients of the regional network in Cologne, Germany, and the surrounding area, is online. The Kidney in COVID-19 Registry aims for the anonymous retrospective collection of clinical data of the following nephrology patients groups with COVID-19 infection:

  1. Patients with pre-existing dialysis (Haemodialysis peritoneal dialysis)
  2. Patients with acute kidney injury in the disease course of COVID-19
  3. Patients with pre-existing chronic kidney diseases
  4. Patients with kidney transplants

We suggest documentation of clinical cases 3-4 weeks after the day of diagnosis of COVID-19. Data entry to the Kidney in COVID-19 Registry can be found on the general data protection compliant platform clinicalsurveys.net and is secured by password.
Please mail us your affiliation at kidneyinfection@uk-koeln.de and your personal account for clinicalsurveys.net will be set-up.

Latest Research

COVID-19, a disease caused by a novel coronavirus, is a major global human threat that has turned into a pandemic. This novel coronavirus has specifically high morbidity in the elderly and in comorbid populations. Uraemic patients on dialysis combine an intrinsic fragility and a very frequent burden of comorbidities with a specific setting in which many patients are repeatedly treated in the same area (haemodialysis centres). Moreover, if infected, the intensity of dialysis requiring specialized resources and staff is further complicated by requirements for isolation, control and prevention, putting healthcare systems under exceptional additional strain. Therefore, all measures to slow if not to eradicate the pandemic and to control unmanageably high incidence rates must be taken very seriously. The aim of the present review of the European Dialysis (EUDIAL) Working Group of ERA-EDTA is to provide recommendations for the prevention, mitigation and containment in haemodialysis centres of the emerging COVID-19 pandemic. The management of patients on dialysis affected by COVID-19 must be carried out according to strict protocols to minimize the risk for other patients and personnel taking care of these patients. Measures of prevention, protection, screening, isolation and distribution have been shown to be efficient in similar settings. They are essential in the management of the pandemic and should be taken in the early stages of the disease.

Here, we review the most recent findings on the effects of SARS-CoV-2 infection on kidney diseases, including acute kidney injury, and examine the potential effects of ARBs on the outcomes of patients with COVID-19. Lastly, we discuss the clinical management of COVID-19 patients with existing chronic renal disorders, particularly those in dialysis and with kidney transplants.

Organisation and therapeutical recommendations including the Brescia COVID-19 respiratory severity score facilitating clinical assessment of nephrology patients.

Alberici F et al. on behalf of the Brescia Renal Covid Task Force. https://www.era-edta.org/en/wp-content/uploads/2020/03/COVID_guidelines_finale_eng-GB.pdf

The Renal Association recently published guidlines for the management of immunosuppressive therapy in patients with autoimmune conditions during the COVID-19 pandemic. They give advices on, if and how to continue or adapt treatment plans. Further they created stratified risk profiles as decision support for a prolonged self isolation. For futher information:

Last week the journal International Urology and Nephrology presented the first results of a meta- analysis including four studies with a total of 1389 COVID-19 patients. They found that out of this 1389 patients, 273 developed a severe disease progression and that there is a significant correlation to patients with chronic kidney diseases. They conclude, physicians should pay extra attention on this vulnerable group of patients.

Overview of the therapeutic options for patients with kidney diseases in the course of COVID-19- infection. This abstract includes a table with potential antiviral or other drugs in off lable use with advice for dose adjustment and possible renal adverse events.

Izzedine et al. Kidney Int, 2020. Doi: https://doi.org/10.1016/j.kint.2020.03.015

In contrast to the findings in other cohorts that renal involvement may be a common complication in COVID-19- infected patients (see for example medRxiv preprints https://doi.org/10.1101/2020.03.07.20032599, https://doi.org/10.1101/2020.02.08.20021212 and https://doi.org/10.1101/2020.02.18.20023242v1), this is the conclusion of a study of 116 COVID-19- patients in Wuhan recently published in the American Journal of Nephrology. None of the studied patients fulfilled official diagnostic criteria for acute kidney injury. It should be mentioned though that only eleven of the 116 patients had to be transferred to intensive care unit, which seems to be an important factor for the development of AKI in this patient group.
