Abstract

Abstract: Background and purpose: Studies have shown that some cytokines in COVID‐19 patients were elevated. This study aims to assess whether IL‐10, IL‐1β, IL‐6, MCP‐1, TNF‐α, IP‐10 and IL‐4 serve as potential diagnostic biomarkers of COVID‐19. Methods: The above serum cytokines in COVID‐19 patients and non‐COVID‐19 patients were detected by ELISA and SARS‐CoV‐2 IgM and IgG were detected by the chemiluminescence method. The independent‐sample Mann‐Whitney U test was utilised to compare cytokine levels in different groups and courses, the Levene T‐test and T'‐test were utilised to compare they in different genders and the Spearman correlation test was utilised to analyse the correlation between the cytokine levels with ages and SARS‐CoV‐2 IgG and IgM. Results: Serum levels of IL‐10, IL‐1β, MCP‐1, TNF‐α and IL‐4 in COVID‐19 patients were significantly higher than those in non‐COVID‐19 patients, while IL‐6 were only significantly higher than in healthy people, IP‐10 were significantly lower than in other diseases patients. AUCs of COVID‐19 diagnosed by IL‐10, IL‐1β, IL‐6, MCP‐1, TNF‐α, IP‐10 and IL‐4 were 0.735, 0.775, 0.595, 0.821, 0.848, 0.38 and 0.682, respectively. In the COVID‐19 patients' serum, the levels of IL‐10 and MCP‐1 of male were noticeably higher than those of female, and all cytokines were significantly positively correlated with age, IL‐1β and IL‐4 were significantly negatively correlated with SARS‐CoV‐2 IgM, while IL‐10, IL‐1β, IL‐6, TNF‐ and IP‐10 were significantly negatively correlated with SARS‐CoV‐2 IgG. IL‐10 on 43‐56 days was significantly lower than at 29‐42 days, TNF‐α at 15‐42 days was significantly higher than at 0‐14 days, IP‐10 at 0‐14 days was the highest and IL‐4 at 29‐42 days was significantly higher than at 0‐14 days. Conclusions: The detection of IL‐10, IL‐1 β, IL‐6, MCP‐1, TNF‐α and IL‐4 would assist the clinical study of COVID‐19, and IP‐10 may be the cytokine of early elevation in COVID‐19 patients.
