Association between Qingfei Paidu Granules (清肺排毒颗粒) Initiated at Different Timepoints and Clinical Outcomes in Asymptomatic COVID-19 Omicron Infection Cases
(清肺排毒颗粒, QFPDG) initiated at different time points and clinical outcomes in asymptomatic patients infected with Omicron variant of coronavirus disease 2019 (COVID-19).
Methods
2
This retrospective study recruited asymptomatic Omicron COVID-19 cases who have been treated by QFPDG from Qingdao Hongdao fangcang shelter hospital from 14th March to 19th March, 2022. Patients were divided into four groups: ≤3 days group, 4-6 days group, 7-9 days group and ≥10 days group. The baseline data and duration of viral shedding were compared between groups, multivariate linear regression was used to analyze the influence of age and treatment initiation time on duration of viral shedding. The adverse events and prognosis of the patients were recorded.
Results
2
A total of 111 asymptomatic patients were included. Of them, 50 were males and 61 were females, with the median age of 35 years. Twelve patients had comorbidities. There were four cases in the ≤3 days group, 57 cases in the 4-6 days group, 42 cases in the 7-9 days group, and 8 cases in the ≥10 days group, having no significant differences in age, gender and comorbidities at baseline (
P
>0.05). The median duration of viral shedding was 3.0 (2.3, 3.0) days, 7.0 (7.0, 8.0) days, 9.0 (8.0, 10.0) days, and 11.0 (11.0, 12.0) days in the groups of ≤3 days, 4-6 days, 7-9 days and ≥10 days, respectively, with significant difference between groups (
P
<0.001). The multivariate linear regression showed that there was no correlation between age and duration of viral shedding (
β
= 0.008,
P
= 0.886), while the medication initiation time was positively correlated with duration of viral shedding (
P
<0.001, adjusted
R
2
= 0.8), suggesting that duration of viral shedding increased by 0.885 days as medication was initiated one day later. No serious adverse events occurred during medication, and none of the patients were converted into confirmed cases and were cured and discharged from hospitals.
Conclusion
2
Early treatment with QFPDG is linked to a shorter duration of viral shedding in asymptomatic cases infected with Omicron variant of COVID-19.
