AIM: Vitamin D, which has immunomodulatory effect, can reduce risk of infections and concentrations of proinfl ammatory cytokines. The aim of this study was to investigate the relationship between the levels of vitamin D and severity of COVID-19. METHODS: A total of 204 patients with COVID-19 disease were enrolled in the study. All patients had viral pneumonia, which was confi rmed with chest computer tomography. All cases were divided in two groupsmild (outpatients); and serious (inpatients)-according to their clinical and laboratory data. Serum vitamin D levels were measured by chemiluminescence method. RESULTS: Vitamin D defi ciency was found in 41.7 % (n = 85) of cases and insuffi ciency was found in 46.0 % (n = 94), while in 12.3 % (n = 25) of cases normal vitamin D levels were found. The odds of having a serious clinical outcome were increased for vitamin D insuffi ciency patients 5.604 times (%95 CI:0.633-49.584) and for vitamin D defi ciency patients 38.095 times (%95 CI:2.965-489.50) for each standard deviation decrease in serum 25(OH)D. CONCLUSION: Adequate levels of vitamin D could suppress infl ammation and reduce the severity of COVID-19. Vitamin D supplementation may have an important role in decreasing the impact of the pandemic (Tab. 5, Fig. 2, Ref. 27
