Summary

2019 new coronavirus (2019-nCoV) infected pneumonia, namely severe acute respiratory infection (SARI) has caused global concern and emergency. There is a lack of effective targeted antiviral drugs, and symptomatic supportive treatment is still the current main treatment for SARI.

Vitamin C is significant to human body and plays a role in reducing inflammatory response and preventing common cold. In addtion, a few studies have shown that vitamin C deficiency is related to the increased risk and severity of influenza infections.

We hypothize that Vitamin C infusion can help improve the prognosis of patients with SARI. Therefore, it is necessary to study the clinical efficacy and safety of vitamin C for the clinical management of SARI through randomized controlled trials during the current epidemic of SARI.

Description

At the end of 2019, patients with unexplained pneumonia appeared in Wuhan, China. At 21:00 on January 7, 2020, a new coronavirus was detected in the laboratory, and the detection of pathogenic nucleic acids was completed at 20:00 on January 10. Subsequently, the World Health Organization officially named the new coronavirus that caused the pneumonia epidemic in Wuhan as 2019 new coronavirus (2019-nCoV), and the pneumonia was named severe acute respiratory infection (SARI). Up to February 4, 2020, over 20000 cases have been diagnosed in China, 406 of which have died, and 154 cases have been discovered in other countries around the world. Most of the deaths were elderly patients or patients with severe underlying diseases. SARI has caused global concern and emergency.

Statistics of the 41 patients with SARI published in JAMA initially showed that 13 patients were transferred into the ICU, of which 11 (85%) had ARDS and 3 (23%) had shock. Of these, 10 (77%) required mechanical ventilation support, and 2 (15%) required ECMO support. Of the above 13 patients, 5 (38%) eventually died and 7 (38%) were transferred out of the ICU. Viral pneumonia is a dangerous condition with a poor clinical prognosis. For most viral infections, there is a lack of effective targeted antiviral drugs, and symptomatic supportive treatment is still the current main treatment.

Vitamin C, also known as ascorbic acid, has antioxidant properties. When sepsis happens, the cytokine surge caused by sepsis is activated, and neutrophils in the lungs accumulate in the lungs, destroying alveolar capillaries. Early clinical studies have shown that vitamin C can effectively prevent this process. In addition, vitamin C can help to eliminate alveolar fluid by preventing the activation and accumulation of neutrophils, and reducing alveolar epithelial water channel damage. At the same time, vitamin C can prevent the formation of neutrophil extracellular traps, which is a biological event of vascular injury caused by neutrophil activation. Vitamins can effectively shorten the duration of the common cold. In extreme conditions (athletes, skiers, art workers, military exercises), it can effectively prevent the common cold. And whether vitamin C also has a certain protective effect on influenza patients, only few studies have shown that vitamin C deficiency is related to the increased risk and severity of influenza infections. In a controlled but non-randomized trial, 85% of the 252 students treated experienced a reduction in symptoms in the high-dose vitamin C group (1g / h at the beginning of symptoms for 6h, followed by 3 * 1g / day). Among patients with sepsis and ARDS, patients in the high-dose vitamin group did not show a better prognosis and other clinical outcomes. There are still some confounding factors in the existing research, and the conclusions are different.

Therefore, during the current epidemic of SARI, it is necessary to study the clinical efficacy and safety of vitamin C for viral pneumonia through randomized controlled trials.
