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Preprints are preliminary research reports that have not been certified by peer review.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:
Severe cytokine storm syndrome (CSS) is considered as the cause of death among critically ill COVID-19 cases. Early identification of the high-risk severe cases is crucial to lower the fatality and healthcare costs.Methods:
In this study, we retrospectively analyzed the first and second-week serum levels of IL-6, IL-8, and IL-10 of 50 COVID-19 cases. We calculated the ratios of IL-6/IL-10 and IL-8/IL-10 at 3rd, 6th, 9th, and 12th days of hospitalization.Results:
We collected 50 COVID-19 cases (male 54%, mean age 51.2, range 18 - 86), including 39 mild cases (78%), 7 severe/recovered cases (14%), and 4 died cases (8%).The ratios of IL 6/IL-10 and IL-8/IL-10 among mild cases were below 27 (the highest, 26.9) along the 4 testing points of two week hospitalization, while we found that the IL-6/IL-10 and IL-8/IL-10 ratios were as high as 187.51 and 225.3 respectively in the death group on 3rd day with the highest IL-6/IL-10 ratio of 297.28 on the 6th day of hospitalization.Conclusions:
Our preliminary results suggest that the ratios of IL-6/IL-10 and IL-8/IL-10 at the early stage (the first two weeks) of COVID-19 could be a predictive marker for the disease prognosis, of which the cut-off lines were suggested below 50 for a mild and recoverable severe cases.
