Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
 
*, now known with p < 0.00000000001 from 120 studies, recognized in 7 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

RCT on calcifediol (25-hydroxyvitamin D) treatment for hospitalized COVID-19 patients showing significantly reduced intensive care unit admissions.
All patients received standard care including HCQ+AZ. Significantly lower ICU admission with the addition of calcifediol - adjusted odds ratio 0.03 [0.003-0.25]. No deaths for calcifediol (0/50), 2 deaths for SOC (2/26).
For additional analysis see medrxiv.org.
Meta analysis shows that late stage treatment with calcitriol / calcifediol (or paricalcitol, alfacalcidol, etc.) is more effective than cholecalciferol: 65% [41‑79%] lower risk vs. 39% [26‑49%] lower risk. Cholecalciferol requires two hydroxylation steps to become activated - first in the liver to calcifediol, then in the kidney to calcitriol. Calcitriol, paricalcitol, and alfacalcidol are active vitamin D analogs that do not require conversion. This allows them to have more rapid onset of action compared to cholecalciferol. The time delay for cholecalciferol to increase serum calcifediol levels can be 2-3 days, and the delay for converting calcifediol to active calcitriol can be up to 7 days.
This is the 1st of 29 COVID-19 RCTs for vitamin D, which collectively show efficacy with p=0.0000035.
This is the 3rd of 120 COVID-19 controlled studies for vitamin D, which collectively show efficacy with p<0.0000000001 (1 in 226 sextillion).
Study covers vitamin D and HCQ.
risk of death, 85.4% lower, RR 0.15, p = 0.11, treatment 0 of 50 (0.0%), control 2 of 26 (7.7%), NNT 13, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
risk of ICU admission, 94.2% lower, RR 0.06, p = 0.008, treatment 1 of 50 (2.0%), control 13 of 26 (50.0%), NNT 2.1, odds ratio converted to relative risk.

Calcifediol can rapidly in­ crease serum 25OHD concentration. We therefore evaluated the effect of calcifediol treatment, on Intensive Care Unit Admission and Mortality rate among Spanish patients hospitalized for COVID-19. Design: Parallel pilot randomized open label, double-masked clinical trial. Setting: University hospital setting (Reina Sofia University Hospital, Córdoba Spain.) Participants: 76 consecutive patients hospitalized with COVID-19 infection, clinical picture of acute respiratory infection, confirmed by a radiographic pattern of viral pneumonia and by a positive SARS-CoV-2 PCR with CURB65 severity scale (recommending hospital admission in case of total score > 1). Procedures: All hospitalized patients received as best available therapy the same standard care, (per hospital protocol), of a combination of hydroxychloroquine (400 mg every 12 h on the first day, and 200 mg every 12 h for the following 5 days), azithromycin (500 mg orally for 5 days. Eligible patients were allocated at a 2 calcifediol:1 no calcifediol ratio through electronic randomization on the day of admission to take oral calcifediol (0.532 mg), or not. Patients in the calcifediol treatment group continued with oral calcifediol (0.266 mg) on day 3 and 7, and then weekly until discharge or ICU admission. Outcomes of effectiveness included..
