Abstract

Introduction: There is lack of universal agreement on the management of COVID-19. Intravenous high dose vitamin C (HDVC), remdesivir (RDV), and favipiravir (FPV) have been suggested as part of the treatment regimens and only RDV is approved by the Food and Drug Administration (FDA) so far. There is no study in Lebanon that addresses the descriptive cohort of HDVC and antiviral therapy amongst COVID-19 inpatients. Our goal was to highlight such a cohort.

Methodology: A retrospective electronic chart review of COVID-19 inpatients was done over a period of 10 months (August 2020 to April 2021). Comparative data analysis was performed between HDVC and non-HDVC (NHDVC) groups, and RDV and FPV groups.

Results: Among HDVC patients, 70.1% (p = 0.035) and 67.2% (p = 0.008) had dyspnea and desaturation respectively. Patients on HDVC were less likely to remain in hospital for more than 20 days (p = 0.003). HDVC patients were more likely to be on oxygen therapy with 74.7% (p = 0.002). RDV patients were more likely to be on other COVID-19-related medications during hospitalization including the use of tofacitinib, baricitinib, tocilizumab, and anticoagulation as recommended in the guidelines. Statistical significance was noted for the status on discharge as 90.1% of the patients that received RDV were discharged after clinical improvement, compared to the 74.2% of the FPV patients.

Conclusions: Further research is needed to establish local guidelines for the treatment of COVID-19. A significant role of HDVC and FPV might resurface if randomized control trials are conducted.
