Description:
Background: Several studies have suggested the positive impact of vitamin D on patients
infected with SARS-CoV-2. This systematic review aims to evaluate the effects of vitamin D
supplementation on clinical outcomes and mortality rate of COVID-19 patients.
Methods: A comprehensive search was conducted through the databases of PubMed, Scopus,
Web of Knowledge, Embase, Ovid, and The Cochrane Library without time and language
limitation, until December 16, 2020. The results were screened, and the outcomes of interest
were extracted. Using the Joanna Briggs Institute (JBI) Critical Appraisal Tools, the remaining
results were appraised critically. Statistical analysis was performed using the Comprehensive
Meta-Analysis (CMA) software version 2.0.
Results: Of the 2311 results, four studies and 259 patients were enrolled, including 139 patients
in vitamin D intervention groups. The pooled analysis of three studies, reporting the patients’
survival and mortality rate, showed a significantly lower mortality rate among the intervention
groups compared with the control groups (OR=0.264, 95% CI=0.099–0.708, p-value=0.008).
Two of the studies reported the clinical outcomes based on the World Health Organization’s
Ordinal Scale for Clinical Improvement (OSCI) score for COVID-19, where both of them
showed a significant decrease in OSCI score in the vitamin D intervention groups. One study
reported a lower rate of intensive care unit (ICU) admission, and one study reported a significant
decrease in serum levels of Fibrinogen.
Conclusion: Prescribing vitamin D supplementation to patients with COVID-19 infection seems
to decrease the mortality rate, the severity of the disease, and serum levels of the inflammatory
markers. Further studies are needed to determine the ideal type, dosage, and duration of
supplementation
