INTRODUCTION: Our aim was to investigate the efficacy of vitamin C, melatonin, and zinc in patients with severe Covid-19.
METHODS: Twenty-one adult patients were randomized 1:1 to standard care alone or standard care plus IV vitamin C (2 g, q6hr), oral melatonin (6 mg, q6hr), and oral zinc sulfate (50 mg, q6hr) for 10 days. Patients were monitored for changes in hypoxemia and inflammatory markers.
RESULTS: Both treatment modalities were effective to improve PaO2/FiO2 and oxygen saturation. However, there were no significant differences between 2 groups (P > 0.05). There were reductions in CRP, ESR, and LDH levels in both study groups, although not significant. No significant difference was noted in length of ICU stay between 2 groups (P = 0.3).
CONCLUSION: Our study suggests that addition of vitamin C, melatonin, and zinc to standard care is not associated with considerable improvement in patients with severe Covid-19.
