Abstract
Description
Background and purpose: COVID-19 is a viral respiratory disease that results in high mortality. Evidence suggests that micronutrients affect viral and bacterial infections. This study was performed to evaluate the effectiveness of micronutrients (vitamin D, vitamin C and selenium) on the disease severity in patients hospitalized with COVID-19.
Materials and methods: This retrospective cross-sectional study was carried out in patients with diagnosis of COVID-19 in Almahmodia Hospital, 2020. Medical records were reviewed and 42 were selected. Data of patients that received micronutrients including vitamin D, vitamin C and selenium and those that did not receive these supplements were compared. Duration of hospitalization, respiratory support, oxygen therapy, requiring invasive/non-invasive mechanical ventilation, and incident of death were investigated. Statistical analysis was done in SPSS V25.
Results: Survival rates in the groups receiving vitamin C, D and selenium were not significantly different from the groups that did not receive these supplements (P= 0.42, 0.63, 0.084, respectively). The study showed no significant relationship between vitamin D, C, and selenium intake and the need for ventilation due to respiratory distress (P= 0.139, 0.2 and 0.8, respectively).
Conclusion: No remarkable difference was seen between the recipients of vitamin C, D and selenium and those who did not receive supplements in terms of survival and the need for mechanical ventilation. So, these supplements did not affect the clinical outcomes of patients with COVID-19.
