Klimawandel und Gesundheit: Was Sie in der Hausarztpraxis wissen müssen und tun können

Die Folgen des Klimwandels haben einen direkten Einfluss auf die Primärversorgung in Deutschland: Hitzeschutz insbesondere bei älteren Patienten, die Zunahme von Infektionen und die Verlängerung der Allergiesesaison spielen medizinisch eine bedeutsame Rolle. Aber auch in der Prävention und der Aufklärung der Patienten kommt den Hausärztinnen und -ärzten eine besondere Rolle zu. Direkt aus der Praxis berichtet im Live-Webinar am 13. Mai von 18 bis 19 Uhr unser Experte Dr. med. Robin Maitra.

Abstract

Background and Aims

Vitamin C appears to be a viable treatment option for patients with COVID-19.

Methods

We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) of vitamin C versus comparative interventions in patients with COVID-19. The outcome of interest was all-cause mortality.

Results

The meta-analysis of eleven trials using a random-effects model revealed significant reduction in the risk of all-cause mortality with the administration of vitamin C among patients with COVID-19 relative to no vitamin C (pooled odds ratio = 0.53; 95% confidence interval 0.30–0.92). Subgroup analysis of studies that included patients with severe COVID-19 also produced findings of significant mortality reduction with the administration of vitamin C relative to no vitamin C (pooled odds ratio = 0.47; 95% confidence interval 0.26–0.84).

Conclusion

Overall, evidence from RCTs suggests a survival benefit for vitamin C in patients with severe COVID-19. However, we should await data from large-scale randomized trials to affirm its mortality benefits.
