Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Objective This study aimed to describe the clinical features of maintenance hemodialysis (MHD)patients with COVID-19 and potential factors related to the time to return negative RT-PCR in discharged.Methods Retrospective analysis was performed on the clinical data of 90 MHD patients and 134 non-dialysis patients who infected with COVID-19 and admitted to our hospital from 1 April 2022 to 10 June 2022.Results The average age of the MHD patients with COVID-19 was 64.8 ± 12.9 years old and 59.3% patients were males. 12.2% MHD patients with COVID-19 were admitted to ICU and they had higher levels of WBC, neutrophils and procalcitonin(PCT)(P < 0.05) and more symptoms of nausea or vomiting at admission(P = 0.0003). The mean lengths of time from positive to two consecutive negative COVID-19 PCR was 18.15 ± 6.37 days in discharged MHD patients and 11.18 ± 3.52 days in non-dialysis patients(P < 0.0001). Discharged MHD patients with hypertension and DM need obviously longer time to negative than without comorbid disease(21.33 ± 7.03 days vs 16.47 ± 3.6, P = 0.0194). Longer time to negative PCR was associated with lower level of Ct-ORF1ab RNA and Ct-N RNA at admission (R2 = 0.05958, P = 0.0291; R2 = 0.06719, P = 0.0202) in MHD patients.Conclusion MHD patients with COVID-19 had a high probability of admitting to ICU and the level of inflammatory indicators were critical factors. It takes a week longer for MHD patients to return negative PCR than non-dialysis patients. MHD patients combined with hypertension and DM, lower level of Ct- RNA need longer SARS-CoV-2 RNA clearance time than others.
