Abstract
Numerous studies have shown that chronic renal failure, whatever the treatment, is an important risk factor during the SARS-Cov2 pandemic. We present the incidence of COVID-19 infection, and its lethality, in France according to data from the French Language Peritoneal Dialysis Registry (RDPLF), during the period of the epidemic peak between March 1 and May 15, 2020.
 Of the 3,104 patients treated with PD during this period, from 156 centers, 59 contracted COVID-19, ie 1.8%, a percentage significantly lower than that observed in center hemodialysis. Diabetes was found in 64% of infected patients while it was only present in 36% of uncontaminated patients. The mode of contamination was attributed to a hospital stay in 19% of the cases, a family infection in 17% of the cases, treatment in nursing homes in 15% of the cases, unknown in 44% of the cases. Sixty-two percent of the infected patients were on assisted PD, without identifying the source of contamination. The mortality rate was high at 40%, comparable to other countries in PD. A comparison with hemodialysis could only be made after adjustment for comorbidities and patient profiles: data on hemodialysis are not available in the RDPLF.
 Home peritoneal dialysis decreases the risk of Covid-19 contamination, but associated comorbidities and age are the source of high mortality. Non-autonomous patients have a higher risk of contamination.

Summary
Situation de l’épidémie de Covid-19 chez les patients en dialyse péritonéale au 15/05/2020 en France base de données du RDPLF (Situation of the Covid-19 epidemic in patients on peritoneal dialysis on 2020/15/05 in France : RDPLF data-base). Nous présentons l’incidence de l’infection au COVID-19, et sa létalité, en France, d’après les données du Registre de Dialyse Péritonéale de Langue Française, au cours de la période du pic épidémique entre le 1er mars et le 15 mai 2020. Sur les 3 104 patients traités par DP durant cette période, issus de 156 centres, 59 ont contracté le COVID-19 soit 1,8 %, pourcentage nettement inférieur à celui observé en hémodialyse en centre. Une comparaison avec l’hémodialyse ne pourrait être faite qu’après ajustement sur les comorbidités et profils des patients : les données en hémodialyse ne sont pas disponibles dans le RDPLF. La dialyse péritonéale à domicile diminue le risque de contamination par le Covid-19, mais les comorbidités associées et l’âge sont la source d’une mortalité élevée. Les patients non autonomes ont un risque de contamination plus important
