Correlation analysis between serum uric acid and clinical features of patients with novel coronavirus pneumonia

Objective: To analyze the correlation between serum uric acid and clinical features of patients with novel coronavirus pneumonia(COVID-19). Methods: A total of 200 patients with COVID-19 admitted to Wuhan Lei Shen Shan hospital from January 20, 2020 to April 10, 2020 were included in this retrospective cohort study. The patients were divided into the hyperuricemia group and the non-hyperuricemia group. The data of patients were collected through electronic medical record system. SPSS 19.0 and Graphpad Prism 8.0 statistical software were used to compare clinical features, laboratory results, survival time, and prognosis of patients between hyperuricemia and non-hyperuricemia groups. Results: Compared with the non-hyperuricemia group, the hyperuricemia group showed a higher BMI and mortality(P <0.05)as well as higher white blood cell count, lymphocytes, serum creatinine, creatine kinase, cystatin C, myoglobin, interleukin(IL)-6 levels(P <0.05). Serum uric acid level was positively correlated with lymphocytes, hemoglobin, albumin, creatinine, creatine kinase, cystatin C, D-dimer levels while negatively correlated with IL-2 receptor and IL-8. The patients with hyperuricemia had significantly shorter survival time and worse prognosis than those without hyperuricemia(P =0.04). Conclusion: COVID-19 patients with hyperuricemia show higher mortality and worse prognosis compared with the patients with non-hyperuricemia. Copyright © 2021 by the Chinese Medical Association.
