Chawki S, Buchard A, Sakhi H, et al. - This study shows the long-term impact of COVID-19 among patients on maintenance hemodialysis (MHD), revealing both initial and long-term severity of the disease, including severe cachexia.

• This is a retrospective analysis of MHD patients affected by COVID-19 in 19 MHD centers in the Paris, France area.

• An initial mortality rate of 18%, and association of age, comorbidities, dyspnea and previous immunosuppressive treatment with death <30d was noted in this cohort of 248 patients.

• Of 203 patients who survived acute phase, long-term follow-up (median 180d) was reported for 189 (93%) patients.

• Major adverse events occurred in 30 (16%) cases during follow-up, and overall the main major adverse events included cardiovascular events, infections and gastrointestinal bleeding.

• A total of 25/189 (13%) patients experienced post-COVID-19 cachexia, and lower initial albuminemia was significantly linked with this cachexia. No reinfection with SARS-CoV-2 occurred.
