A single-oral bolus of 100,000 IU of cholecalciferol at hospital admission did not improve outcomes in the COVID-19 disease: the COVID-VIT-D — a randomised multicentre international clinical trial
et al., BMC Medicine, doi:10.1186/s12916-022-02290-8
RCT 274 very late stage (>80% pulmonary involvement at baseline) hospitalized COVID-19 patients treated with a single dose of cholecalciferol, and 269 control patients, showing no significant differences. High serum calcidiol levels at admission were associated with lower pulmonary involvement, shorter hospitalization, and lower ICU admission.Serum levels increased in the treatment group, however average levels were still insufficient at discharge. Calcifediol or calcitriol, which avoids several days delay in conversion, may be more successful, especially with this very late stage usage.COVID-VIT-D. 100,000IU cholecalciferol. NCT04552951.
