RCT with 56 cholecalciferol and 54 control hospitalized patients with vitamin D insufficiency or deficiency in Russia, showing positive effects on immune status. The median age in the treatment group was 7 years lower and deficiency was less common, while baseline treatment group CT lung involvement and supplemental oxygen use was higher in the treatment group. Treatment increased vitamin D levels and neutrophil and lymphocyte counts, decreased CRP levels, and was associated with a decrease in CD38++CD27 transitional and CD27−CD38+ mature naive B cells and an increase in CD27−CD38− DN B cells.
risk of ICU admission, 85.9% lower, RR 0.14, p = 0.11, treatment 0 of 56 (0.0%), control 3 of 54 (5.6%), NNT 18, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm), day 9.
risk of oxygen therapy, 7.0% lower, RR 0.93, p = 0.85, treatment 27 of 56 (48.2%), control 28 of 54 (51.9%), NNT 27, baseline oxygen supplementation was higher in the treatment group, 38 vs. 32, day 9.

Box 641603, San Francisco, CA 94164-1603, USA; williamgrant08@comcast.net Correspondence: karonova@mail.ru Abstract: Recent studies showed that a low 25-hydroxyvitamin D (25(OH)D) level was associated with a higher risk of morbidity and severe course of COVID-19. Our study aimed to evaluate the effects of cholecalciferol supplementation on the clinical features and inflammatory markers in patients with COVID-19. A serum 25(OH)D level was determined in 311 COVID-19 patients. Among them, 129 patients were then randomized into two groups with similar concomitant medication. Group I (n = 56) received a bolus of cholecalciferol at a dose of 50,000 IU on the first and the eighth days of hospitalization. Patients from Group II (n = 54) did not receive the supplementation. We found significant differences between groups with the preferential increase in serum 25(OH)D level and ∆ 25(OH)D in Group I on the ninth day of hospitalization (p < 0.001). The serum 25(OH)D level on the ninth day was negatively associated with the number of bed days (r = −0.23, p = 0.006); we did not observe other clinical benefits in patients receiving an oral bolus of cholecalciferol. Moreover, in Group I, neutrophil and lymphocyte counts were significantly higher (p = 0.04; p = 0.02), while the C-reactive protein level was significantly lower on the ninth day of hospitalization (p = 0.02). Patients with supplementation of 100,000 IU of cholecalciferol, compared to those without supplementation, showed a decrease in the frequencies of CD38++CD27 transitional and CD27−CD38+ mature naive B cells (p = 0.006 and p = 0.02) and an increase in the level of CD27−CD38− DN B cells (p = 0.02). Thus, the rise in serum 25(OH)D level caused by vitamin D supplementation in vitamin D insufficient and deficient patients may positively affect immune status and hence the course of COVID-19.
