Abstract
Hemodialysis patients are susceptible to coronavirus disease 2019 (COVID-19). The aim of this study was to describe the epidemiological, clinical characteristics, and mortality-related risk factors for those who undergoing hemodialysis with COVID-19. We conducted a retrospective study. A total of 49 hemodialysis patients with COVID-19 (Group 1) and 74 uninfected patients (Group 2) were included. For patients in Group 1, we found the median age was 62 years (36-89 years), 59.3% were male, and the median dialysis vintage was 26 months. Twenty-eight patients (57%) had three or more comorbidities and two patients (4%) died. The most common symptoms were fever (32.7%) and dry cough (46.9%), while nine patients (18.4%) were asymptomatic. Blood routine tests indicated lymphocytopenia, the proportion of lymphocyte subsets was generally reduced, and chest CT scans showed ground-glass opacity (45.8%) and patchy shadowing (35.4%). However, these findings were not specific to hemodialysis patients with COVID-19, and similar manifestations could be found in patients without SARS-CoV-2 infection. In conclusion, for hemodialysis patients with COVID-19, lymphocytopenia and ground-glass opacities or patchy opacities were common but not specific to them, early active treatment and interventions against nosocomial infection can significantly reduce the mortality and the risk of SARS-CoV-2 infection.
