Vitamin D levels affect survival rates of COVID-19 patients

Abstract

Objective: Vitamin D gained significant popularity, after the COVID-19 pandemic and recent upper respiratory viral infections affecting all over the world as a potential preventative measure against the viral infections. This study aims to evaluate vitamin D levels with the survival rates of the COVID-19 patients. Method: The study included 540 adult patients admitted to pandemic outpatient clinics and hospitalized with a COVID-19 diagnosis. The survival data of the patients hospitalized with COVID-19 diagnosis were compared with vitamin D levels regarding age and gender. Results of the tests were accepted as significant in case when the p-value was smaller than 0.05. Results: The mean value of the vitamin D levels in patients who died due to COVID-19 related complications were significantly lower than the values of survived patients (6.11±1.04 μg/L vs 10.9±1.06 μg/L, p<0.05). Vitamin D levels of the patients did not differ according to the ages of the patients. However, the lowest vitamin D levels were determined among older women. Conclusion: The data revealed that low vitamin D levels were highly related with the survival of COVID-19 patients. Further researches are necessary to assess the potential of vitamin D in fighting viral infections.
