ABSTRACT
BACKGROUND:
Severe COVID-19 caused by SARS-CoV-2 should closely be cared because of the relatively high mortality rate. If SARS-CoV-2 could be cleared as soon as possible, the mortality rate might lower. In the present study, we analyzed factors which might be related to the clearance of SARS-CoV-2.METHODS:
One hundred and twenty-eight severe COVID-19 cases were enrolled. All of them had been isolated and treated at Shenzhen Third People's Hospital because they were positive for nucleic acid of SARS-CoV-2 tested by qRT-PCR. Their baseline clinical characteristics and antiviral regimens were collected and analyzed, respectively.RESULTS:
Of the 128 enrolled severe COVID-19 cases, unfortunately 3 died. The mean viral duration of all patients was 23.5 (range 17-32) days. All patients achieved viral clearance during 9 weeks. 13.4% of patients achieved viral clearance within 2 weeks, and 63.0% of patients achieved viral clearance within 4 weeks. The combined regimens of three or more antiviral drugs, the use of invasive mechanical ventilation, and late admission might be related to the delay of viral clearance within 2 weeks. The use of arbidol, the use of invasive mechanical ventilation, and late admission might be related to the delay of viral clearance within 4 weeks. Patients often had a prolonged course of COVID-19 and hospitalization, and were more likely transferred to intensive care unit (ICU) for treatment, if they could not clear SARS-CoV-2 during 23 days.CONCLUSION:
Severe COVID-19 cases should be admitted to hospital as soon as possible. The combined regimens of three or more antiviral drugs might not be useful for viral clearance, and should be performed carefully and cautiously.Keywords
