Background and Objectives: Patients on maintenance hemodialysis (MHD) are at high risk for coronavirus disease 2019 (COVID-19). However, patients undergoing MHD who are infected with COVID-19 are not fully studied. The objective of this study is to describe the characteristics of patients with COVID-19 undergoing MHD and provide a basis for the recognition and prevention of COVID-19 infection. Materials and Methods: Patients undergoing MHD were assigned into the normal group (537 cases), diagnosed group (66 cases), and suspected group (24 cases). General data, clinical symptoms, hemodialysis indicators, and laboratory indicators were collected and compared. Results: A total of 627 patients undergoing MHD were evaluated. The prevalence of COVID-19 was 10.53% (66/627), mortality was 18.18% (12/66), and death rate was 1.91% (12/627). In addition, 26% of patients were asymptomatic. Cough was the most common symptom (36%), followed by fatigue (16%), dyspnea (16%), and fever (13%). Ultrafiltration volume, ultrafiltration rate, and the duration of weekly dialysis in the diagnosed group were significantly lower than those in the other two groups. Moreover, neutrophil ratio and neutrophil, monocyte, and total carbon dioxide levels in the diagnosed group were significantly higher than those in the normal group, and the lymphocyte ratio was considerably lower than in the normal group. Sixty-five of the suspected and diagnosed patients had positive pulmonary CT findings. Conclusion: Compared with the general population, patients on hemodialysis have a significantly higher risk of contracting COVID-19 and postinfection mortality. Moreover, most patients undergoing hemodialysis have no obvious clinical symptoms after infection with COVID-19 but only have pulmonary changes which make it particularly important to screen and manage patients undergoing hemodialysis on outpatient basis.
