Retrospective 13 COVID-19 patients and 7 controls in Brazil, showing higher prevalence of vitamin D deficiency for COVID-19 cases, without statistical significance.
This is the 102nd of 175 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 18 vigintillion).
This study includes vitamin D and zinc.
risk of case, 45.7% lower, RR 0.54, p = 0.16, high D levels (≥20ng/mL) 4 of 9 (44.4%), low D levels (<20ng/mL) 9 of 11 (81.8%), NNT 2.7.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

COVID-19 in 2020 brought challenges to the Brazilian public health system with an emerging virus with respiratory contagion called SARS-CoV-2. There are few studies in Brazil and in some countries, on the increased incidence of certain viral respiratory infections, including H1N1 and coronavirus and their association with low levels of vitamin D, zinc and iron. The aim of this study was to demonstrate that the deficit of vitamin D, zinc and iron has an impact on the infectious process of patients with COVID-19 and to establish new forms of prevention for the worsening of COVID-19 in the human body. Data were collected from medical records and test results from patients being followed up during the treatment period for COVID-19. Patients with low blood levels of vitamin D, zinc and iron during the treatment period of COVID-19 had a higher percentage of worsening and complications requiring hospitalization in intensive care beds. The ingestion of vitamin D, zinc and iron in the treatment period of patients with COVID-19 in addition to being an immunological protector against SARS-CoV-2 and alleviating the process of worsening the disease can also act as a biomarker in cases of this disease.
