ABSTRACT
OBJECTIVES:
Vitamin C has anti-inflammatory effects. This review aimed to investigate the therapeutic effect of high-dose intravenous vitamin C (HDIVC) in patients with coronavirus disease 2019 (COVID-19).METHODS:
The following key phrases were searched for article inclusion "Vitamin C OR ascorbic acid" AND "COVID-19 OR coronavirus disease 2019 OR severe acute respiratory syndrome coronavirus 2 OR SARS-CoV-2â³. Articles that utilized HDIVC for the management of patients with COVID-19 were included, whereas review articles and case reports were excluded from this review. Moreover, we performed a meta-analysis to evaluate whether HDIVC can reduce the length of hospital stay and in-hospital mortality rate of patients with severe COVID-19.RESULTS:
In total, eight articles were included in this review, and five studies were included in the meta-analysis. The length of hospital stay was not significantly different between the HDIVC and control groups. Also, although our meta-analysis showed a tendency for HDIVC to reduce the in-hospital mortality rate in patients with severe COVID-19, the in-hospital mortality rate was not significantly different between patients treated with HDIVC and those who did not receive HDIVC.CONCLUSIONS:
Evidence supporting the therapeutic use of HDICV in COVID-19 patients is lacking. Further studies are required for drawing a clear conclusion on this topic.Keywords
