“…Daneshkhah et al 24 observed that high C‐reactive protein (CRP) was inversely correlated with 25(OH)D, and they thought vitamin D to have a possible role in reduction of complications caused by abnormal inflammation and cytokine storm given the CRP as a marker for cytokine storm and considering its association with vitamin D deficiency. Some previous studies found negative correlation between 25(OH) D vitamin level and pneumonia severity, CRP level, increased risk of sepsis, ARDS risk and increased production of proinflammatory cytokines, such as IL‐6 25–29 …”

Objective Coronavirus disease 2019 (COVID‐19) is a global health problem that can result in serious complications. The aim of this study was to investigate the prevalence and clinical importance of vitamin D deficiency in children with COVID‐19. Material and Methods This study includes 40 patients who were diagnosed to have COVID‐19 and hospitalized with the real‐time reverse transcription polymerase chain reaction method, 45 healthy matched control subjects with vitamin D levels. The age of admission, clinical and laboratory data, and 25‐hydroxycholecalciferol (25‐OHD) levels were recorded. Those with vitamin D levels which are below 20 ng/ml were determined as Group 1 and those with ≥20 ng/ml as Group 2. Results Patients with COVID‐19 had significantly lower vitamin D levels 13.14 μg/L (4.19–69.28) than did the controls 34.81 (3.8–77.42) μg/L (p < .001). Patients with COVID‐19 also had significantly lower serum phosphorus (4.09 ± 0.73 vs. 5.06 ± 0.93 vs. (U/L) (p < .001)) values compared with the controls. The symptom of fever was significantly higher in COVID‐ 19 patients who had deficient and insufficient vitamin D levels than in patients who had sufficient vitamin D levels (p = .038). There was a negative correlation found between fever symptom and vitamin D level (r = −0.358, p = .023). Conclusion This is the first to evaluate vitamin D levels and its relationship with clinical findings in pediatric patients with COVID‐19. Our results suggest that vitamin D values may be associated with the occurrence and management of the COVID‐19 disease by modulating the immunological mechanism to the virus in the pediatric population.

Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths

The world is in the grip of the COVID-19 pandemic. Public health measures that can reduce the risk of infection and death in addition to quarantines are desperately needed. This article reviews the roles of vitamin D in reducing the risk of respiratory tract infections, knowledge about the epidemiology of influenza and COVID-19, and how vitamin D supplementation might be a useful measure to reduce risk. Through several mechanisms, vitamin D can reduce risk of infections. Those mechanisms include inducing cathelicidins and defensins that can lower viral replication rates and reducing concentrations of pro-inflammatory cytokines that produce the inflammation that injures the lining of the lungs, leading to pneumonia, as well as increasing concentrations of anti-inflammatory cytokines. Several observational studies and clinical trials reported that vitamin D supplementation reduced the risk of influenza, whereas others did not. Evidence supporting the role of vitamin D in reducing risk of COVID-19 includes that the outbreak occurred in winter, a time when 25-hydroxyvitamin D (25(OH)D) concentrations are lowest; that the number of cases in the Southern Hemisphere near the end of summer are low; that vitamin D deficiency has been found to contribute to acute respiratory distress syndrome; and that case-fatality rates increase with age and with chronic disease comorbidity, both of which are associated with lower 25(OH)D concentration. To reduce the risk of infection, it is recommended that people at risk of influenza and/or COVID-19 consider taking 10,000 IU/d of vitamin D 3 for a few weeks to rapidly raise 25(OH)D concentrations, followed by 5000 IU/d. The goal should be to raise 25(OH)D concentrations above 40-60 ng/mL (100-150 nmol/L). For treatment of people who become infected with COVID-19, higher vitamin D 3 doses might be useful. Randomized controlled trials and large population studies should be conducted to evaluate these recommendations.
