This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review.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
Background Since March 2022, the SARS-CoV-2 Omicron variant, mainly the BA.2 sub-lineage, has swept throughout Shanghai, China and caused a wide range of infections. Patients with chronic kidney disease (CKD) are particularly vulnerable to the subvariant and have unique clinical manifestations and outcomes, which have not been studied yet.Methods We retrospective collected data from 2140 hospitalized patients with SARS-CoV-2 Omicron infection from March 29, 2022, to May 17, 2022. Demographic characteristics, clinical symptoms, ancillary examination results, and treatments were described respectively. Presence of COVID-19 pneumonia, disease severity (according to WHO), composite outcome (critical COVID-19 and death), and negative conversion time were defined as primary outcomes. Multivariate analyses were used to evaluate risk factors affecting the primary outcomes.Results The main clinical types of CKD group were severe and critical. Negative conversion time varies according to the stage of CKD patients. The CKD group was more likely to have pneumonia, respiratory and circulatory support, severe disease and death, as compared to the non-CKD group. CKD and the number of comorbidities were found to be risk factors for pneumonia, critical COVID-19and composite outcome among Omicron patients.Conclusion We provided the first snapshot of clinical characteristics and outcomes of CKD patients in the Omicron wave, highlighting the vulnerability of CKD population and providing clues for future studies in special or immunocompromised populations.
