Insights
High-dose intravenous vitamin C (HIVC) may reduce inflammation in severe COVID-19 patients. This study found HIVC therapy significantly lowered inflammatory markers, suggesting a potential benefit for hyperinflammation management.
Area of Science:
- Critical care medicine
- Infectious diseases
- Nutritional science
Background:
- Severe COVID-19 is frequently associated with dangerous hyperinflammation.
- Managing inflammatory markers is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the clinical effectiveness of high-dose intravenous vitamin C (HIVC) in mitigating hyperinflammation among severe COVID-19 patients.
Main Methods:
- Retrospective cohort study of hospitalized severe COVID-19 patients.
- Analysis of demographic data, laboratory findings, and inflammatory markers (hs-CRP, IL-6, TNF-α).
- Comparison of inflammatory marker levels before and after HIVC treatment.
Main Results:
- A high prevalence of hyperinflammation was observed in the study cohort.
- Patients receiving HIVC showed significant reductions in inflammatory markers compared to controls.
- HIVC administration was independently associated with greater reductions in inflammatory marker levels.
Conclusions:
- High-dose intravenous vitamin C demonstrates potential in attenuating hyperinflammation in severe COVID-19.
- HIVC may be a beneficial adjunctive therapy for reducing inflammatory markers in critical COVID-19 cases.
Objective:
High-dose intravenous vitamin C (HIVC) is a major concern when treating patients with coronavirus disease 2019 (COVID-19). The aim of this study was to assess the clinical efficacy of HIVC on hyperinflammation in patients with severe COVID-19.
Methods:
This retrospective cohort study included hospitalized patients with severe COVID-19, a subset of whom was treated with HIVC. The medical records were screened for demographic data, laboratory findings, and medications, as well as initial and repeated values of multiple inflammatory markers for analysis.
Results:
A high percentage of patients presented with hyperinflammation based on inflammatory marker levels above the upper limit of normal (high-sensitivity C-reactive protein, 80.1%; interleukin-6, 91.5%; and tumor necrosis factor-α, 67.4%). Eighty-five (36%) patients received HIVC therapy. After treatment with HIVC, the levels of inflammatory markers displayed a significant decrease compared with those of patients without HIVC. Furthermore, the percentages of reduction in inflammatory marker levels were higher in patients receiving HIVC compared with those in patients treated without HIVC. Stepwise multiple linear regression analysis revealed that HIVC was independently associated with percentages of reduction in levels of inflammatory markers.
Conclusions:
HIVC has the potential benefit of attenuating hyperinflammation by reducing inflammatory marker levels in patients with severe COVID-19.
