Retrospective 78 ICU patients in Turkey, showing lower mortality with high-dose vitamin C treatment, without statistical significance. The SOFA score was significantly better with treatment at day 4.
Authors incorrectly state that "HDVC treatment did not reduce the short-term mortality...". Mortality was lower with treatment, although not statistically significant given the sample size.
6g of vitamin C daily in 4 equal doses every 6h, for a total of 96h.
This is the 59th of 71 COVID-19 controlled studies for vitamin C, which collectively show efficacy with p=0.000000038 (1 in 26 million).
21 studies are RCTs, which show efficacy with p=0.0012.
This study is excluded in the after exclusion results of meta analysis: very late stage, ICU patients.

S evere acute respiratory syndrome coronavirus 2 (SARS- CoV-2) causes tissue damage in the endothelium and epithelium, increasing vascular permeability and the risk of lung edema. The expressions of interleukin (IL) 6, IL-2, IL-7, IL-10, interferon gamma, and tumor necrosis factor α are thought to induce an interstitial fibrosis in the lung by causing an abnormal increase (cytokine storm) in plasma levels. [1] [2] [3] When these pathogenic factors are taken into account, a table with high mortality from acute respiratory failure and severe acute respiratory distress syndrome (ARDS) emerges in patients with coronavirus disease (CO-VID-19) followed up in the intensive care unit (ICU). The low Objectives: In our study, we aimed to determine the effect of vitamin C on short-term mortality and length of intensive care unit (ICU) stay in patients with coronavirus disease (COVID-19) followed up in the ICU. Methods: The patients who received and those who did not receive the high-dose intravenous vitamin C protocol were assigned to the treatment and control groups, respectively. The primary study findings in both groups were length of ICU stay and shortterm mortality, while the secondary findings were vasopressor and invasive mechanical ventilation requirements and change in sequential organ failure assessment score from the 0 to the 96th hour. Results: Thirty-eight patients were included in the treatment group and 40 were included in the control group. The mortality rates were 44% and 60% in the treatment and control groups, respectively; however, the difference between the groups was not statistically significant (p>0.05). The median length of ICU stay in both groups was 10 days (p>0.05). No significant differences in the invasive mechanical ventilation and vasopressor requirements were found between the groups (p>0.05). Conclusion: Consequently, the high-dose vitamin C therapy in the patients with acute respiratory failure due to COVID-19 pneumonia did not reduce the length of ICU stay, mortality, and invasive mechanical ventilation and vasopressor reqirements.
