ABSTRACT
BACKGROUND:
We studied patients with coronavirus disease 2019 (COVID-19) infected by severe acute respiratory syndrome coronavirus 2, a virus that originated in Wuhan, China, and is spreading over the country including Jiangsu Province. We studied the clinical characteristics and therapies of severe cases in Jiangsu Province.METHODS:
A multicenter retrospective cohort study was conducted to analyze clinical, laboratory data and treatment of 60 severe cases with COVID-19 infection in Jiangsu Province between January 24, 2020 and April 20, 2020. The improvement and deterioration subgroups were compared to identify predictors of disease progression.RESULTS:
A total of 653 infected cases with COVID-19 were reported in Jiangsu Province, of which 60 severe cases were included in this study. Up until April 20, 2020, the mortality of severe patients was 0%. The median age was 57 years. The average body mass index of these patients was 25 kg/m². White blood cell counts decreased in 45.0% of patients, lymphopenia in 63.3%, thrombocytopenia in 13.3% and procalcitonin levels in 88.3% of the patients were less than 0.5 ng/mL. There were no statistically significant differences in immunoglobulin therapy and GCs therapy between the improvement and deterioration subgroups. Logistic regression analysis identified higher levels of troponin T (odds ratio [OR] 1.04; 95% confidence interval [CI] 1.00-1.08; Pâ¯=â¯0.04), antiviral therapy with aerosol inhalation of interferon (OR 6.33; 95% CI 1.18-33.98; Pâ¯=â¯0.03), and the application of non-invasive mechanical ventilation (OR 1.99; 95%CI 1.17-3.41; Pâ¯=â¯0.01) as predictors of disease progression, whereas higher lymphocyte count (OR 0.11; 95% CI 0.02-0.57; Pâ¯=â¯0.01) and early prone ventilation were associated with improvement (OR 0.11; 95% CI 0.01-0.98; Pâ¯=â¯0.04).CONCLUSIONS:
COVID-19 infection had a low mortality rate in Jiangsu Province, China. The higher levels of troponin T and lower lymphocyte count were predictors of disease progression. Early prone ventilation may be an effective treatment for severe cases.Keywords
