Background:
Remdesivir is a monophosphoramidate prodrug of an adenosine analog, and it has a broad-spectrum antiviral activity against paramyxoviruses, flaviviruses, and coronaviruses. Remdesivir is associated with decreased hospital stay and improved outcomes in coronavirus- disease 2019 (COVID-19).
Methodology:
Of 846 suspected COVID-19 patients admitted to the hospital, 612 SARS-CoV-2 nasopharyngeal RT-PCR positive patients were evaluated for enrollment in this prospective cohort study. 159 RT-PCR positive patients were given remdesivir. Their clinical, biochemical parameters, hospital stay, and outcomes related to morbidity and mortality were followed.
Results:
Out of the 159 patients, 141 recovered after remdesivir use. The Chi-square test for independence examined the relation between the day of the first dose, dose of remdesivir, and clinical outcome. The standardized case fatality ratio (CFR) in the 453 hospitalized patients who did not receive remdesivir was 32.89% (N = 149) as compared to 11.32% (N = 18) in the patients who received remdesivir. These findings are in keeping with the therapeutic value of remdesivir in symptomatic SARS-CoV-2 infection of varying severity.
Conclusion:
The use of remdesivir is associated with a decrease in the severity of the SARS-CoV-2 infection. Its use is also associated with a decreased length of hospital stay and lower mortality than the patients who did not receive remdesivir.
