简要总结
The objective of this study is to evaluate the impact of this HDIVC therapy in the first treatment of symptomatic Covid-19 patients in a time period of one week.
详细描述
We consider that treatment with high doses of injectable vitamin C HDIVC could have a positive impact as an adjunct on the immunity of patients with Covid while reducing the possibility of worsening their clinical picture. Similarly, we wish to evaluate the efficacy of this treatment, for one week, in patients hospitalized in the ICU, in order to reduce the inflammatory burden and reduce hospital stay.
