[Role of the French national registry REIN in the health monitoring of patients with end-stage chronic renal failure infected with SARS-CoV-2: Organization and initial data].

The REIN registry is a national registry held by the French Biomedicine Agency. Its objective is the epidemiological monitoring of patients with end-stage chronic renal failure. This registry, backed by its expertise and its national network, has been able to very quickly set up epidemiological monitoring of chronic dialysis and/or transplant patients affected by SARS-CoV-2. The first results show a relatively low frequency of COVID-19 in dialysis patients (4.9%) contrary to what one might have feared. The frequency of SARS-CoV-2 infection in kidney transplant patients is 1.8% nationwide. All regions of France have not been affected in the same way. The prevalence of COVID-19 patients varied by region, reaching up to 10%. The probability of being affected was higher in men and diabetic patients. At October 19, among 3209 infected patients (dialysis and transplant), 573 died from a cause related to SARS-CoV-2. The case fatality in diagnosed cases was 18%. A weekly newsletter has been set up by the Biomedicine Agency using information transmitted by all of the epidemiological support units in the registry. The REIN registry was able to adapt to become a reactive health monitoring tool.
