Risk factors for prognoses of uremic maintenance dialysis patients with novel coronavirus infection

Objective To retrospectively explore the prognostic factors of uremic maintenance hemodialysis （MHD） patients with novel COVID-19 infection. Methods A total of 556 MHD patients on regular follow-ups were recruited. Baseline profiles and laboratory tests were recorded prior to contracting COVID-19 infection. Results There were 312 males and 244 females with an age of （52.37 ± 14.81） year and an MHD duration of （61.02 ± 43.90） months. Diabetic kidney disease（DKD） was a primary disease （n = 101, 18.1%） with top three complications of diabetes mellitus （DM）（n = 135, 16.3%）, cardiovascular disease （CVD）（n = 48, 6.6%） and stroke （n = 3, 0.5%）. Hemodialysis （n = 192, 34.5%） and peritoneal dialysis （PD）（n = 364, 65.5%） were performed. DM, hemodialysis, age and serum sodium level were risk factors for mortality after COVID-19 infection. And serum prealbumin level was a protective factor. Multivariate regression analysis revealed that MHD and age were independent risk factors for mortality. Cardiovascular disease, MHD,
