PURPOSE: Since the end of 2019, dialysis patients have been at risk of coronavirus disease 2019 (COVID-19) as well as other potential complications. Hence, we sought to describe the clinical characteristics of dialysis patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: We reviewed clinical outcomes, which consisted of clinical data extracted from the medical records of 695 registered dialysis patients at the Dialysis Center of Central Hospital of Wuhan from January 13th, 2020, to February 29th, 2020, and performed statistical analysis. According to the results, there were 447, 227 and 21 hemodialysis (HD), peritoneal dialysis (PD) and combined HD and PD (HD&PD) cases, respectively. RESULTS: During the outbreak of COVID-19, 36 dialysis patients were infected by SARS-CoV-2. Among those 36 patients, 32 (7.2%) were on HD, and 4 (1.8%) were on PD. When comparing SARS-CoV-2 infection between HD and PD, the relative risk was 4.07 (RR = 4.07, 95% CI 1.46–11.35). We noted a median age of 66 years during the observation period, and the number of male patients was 23 (63.9%). There were 15 fatal cases tested positive for SARS-CoV-2 (13 cases on HD and 2 cases on PD). By comparing mortality in the same period of 2018, 2019 and 2020, the all-cause mortality of hemodialysis patients was significantly higher in 2020 (4.89%) than in either 2018 (2.55%) or 2019 (1.97%). There was no significant difference in mortality from all causes excluding COVID-19, during the same period among the 3-year period. However, during the COVID-19 outbreak, the mortality from all causes excluding COVID-19 was 2.73%, which was slightly higher than that from COVID-19 (2.16%). CONCLUSIONS: Although COVID-19 seriously threatens the health of people with uremia, deaths from all causes excluding COVID-19 during the epidemic cannot be ignored.
