Insights
Early oseltamivir treatment for suspected COVID-19 patients without hypoxia reduced fever duration. This antiviral, combined with antibiotics, showed effectiveness in outpatient settings.
Area of Science:
- Infectious Diseases
- Virology
- Public Health
Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, has led to global health challenges since late 2019.
- Investigating effective treatments for COVID-19, particularly in non-hypoxic outpatients, is crucial.
Purpose of the Study:
- To evaluate the effectiveness of oseltamivir in treating COVID-19 suspected outpatients without hypoxia.
- To compare early versus late initiation of oseltamivir treatment.
Main Methods:
- A study involving 16 medical personnel and their families suspected of COVID-19 without hypoxia.
- Patients received a combination of antiviral (oseltamivir) and antibacterial therapy.
- Comparison between early treatment (ET) initiated within 24 hours and late treatment (LT) initiated after 24 hours.
Main Results:
- The study included 10 females (63%), with one patient having diabetes and three with hypertension.
- Early oseltamivir administration (ET) resulted in a significantly shorter fever duration (31 ± 21 hours) compared to late administration (LT) (94 ± 38 hours).
- Fever duration correlated with the time from fever onset to treatment initiation and the time from peak to decline.
Conclusions:
- Early oseltamivir administration, in conjunction with antibacterial therapy, appears to reduce fever duration in COVID-19 suspected outpatients without hypoxia.
- Prompt treatment initiation is associated with better outcomes regarding fever resolution.
Background:
Since December 2019 coronavirus disease 2019 (COVID-19) outbreaks have occurred in China and many countries around the world. The effectiveness of oseltamivir on COVID-19 suspected outpatients without hypoxia was evaluated.
Methods:
A total of 16 COVID-19 suspected medical personnel and their cohabitation families without hypoxia, who came to the adult fever clinic from March to June 2020 were studied. All patients received antiviral therapy (oseltamivir) and antibacterial therapy together.
Results:
Most of the infected patients were female (10, 63%), 1 had diabetes (6%) and 3 hypertension (19%). The median age was 45 years (interquartile range [IQR] 31-60 years). Oseltamivir administration made the temperature fall within 24 h in part (10, 63%). Clinical data were compared between patients receiving early treatment (ET) with oseltamivir, initiated within 24 h, and patients administered late treatment (LT), initiated after this time point. Duration of fever was shorter in the ET group than in the LT group (31 ± 21 h versus 94 ± 38 h; p < 0.001). The time from fever onset to treatment initiation correlated with duration of fever (r = 0.77; p < 0.001) and the time from peak to decline (r = 0.58; p < 0.05).
Conclusion:
These findings suggest that early oseltamivir administration may lower the duration of fever in COVID-19 suspected outpatients without hypoxia when it is used in combination with antibacterial therapy.
