ABSTRACT
Objective:To investigate the correlation between concomitant diabetes mellitus and clinical features in patients with COVID-19.Methods:Fifty patients with COVID-19 admitted to the Sixth People′s Hospital of Shenyang were divided into 2 groups with and without diabetes mellitus. Indexes such as hospitalization days, duration of positive virus-PCR result, secondary infection, duration of fever, rate of liver dysfunction, and rate of cardiac injury were compared between 2 groups.Results:The average hospitalization durations of diabetes group and control group were(24.0±6.8) and(18.4±5.9) days, respectively, and the duration of positive virus-PCR testing results were(16.0±4.5) and(12.3±4.4) days respectively, suggesting longer hospital stay and longer time for virus clearance in the diabetes group than those in the control group(both P<0.05). The rates of secondary infection, severe subtype, liver dysfunction and cardiac injury in the diabetes group increased, though without significant difference( P>0.05). Conclusion:Prolonged duration of positive virus-PCR result and average days of hospitalization in patients with COVID-19 may be associated with diabetes mellitus.
