Small RCT 60 ICU patients in Iran, 30 treated with vitamins A, B, C, D, and E, showing significant improvement in SOFA score and several inflammatory markers at day 7 with treatment.
5,000 IU vitamin A daily, 600,000 IU vitamin D once, 300 IU of vitamin E twice a day, 500 mg vitamin C four times a day, and one ampule daily of B vitamins [thiamine nitrate 3.1 mg, sodium riboflavin phosphate 4.9 mg (corresponding to vitamin B2 3.6 mg), nicotinamide 40 mg, pyridoxine hydrochloride 4.9 mg (corresponding to vitamin B6 4.0 mg), sodium pantothenate 16.5 mg (corresponding to pantothenic acid 15 mg), sodium ascorbate 113 mg (corresponding to vitamin C 100 mg), biotin 60 μg, folic acid 400 μg, and cyanocobalamin 5 μg].
Cholecalciferol was used in this study. Meta analysis shows that late stage treatment with calcitriol / calcifediol (or paricalcitol, alfacalcidol, etc.) is more effective than cholecalciferol: 69% [47‑82%] lower risk vs. 39% [27‑49%] 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.
Bolus treatment is less effective. Pharmacokinetics and the potential side effects of high bolus doses suggest that ongoing treatment spread over time is more appropriate. Research has confirmed that lower dose regular treatment with vitamin D is more effective than intermittent high-dose bolus treatment for various conditions, including rickets and acute respiratory infections1,2. The biological mechanisms supporting these findings involve the induction of enzymes such as 24-hydroxylase and fibroblast growth factor 23 (FGF23) by high-dose bolus treatments. These enzymes play roles in inactivating vitamin D, which can paradoxically reduce levels of activated vitamin D and suppress its activation for extended periods post-dosage. Evidence indicates that 24-hydroxylase activity may remain elevated for several weeks following a bolus dose, leading to reduced levels of the activated form of vitamin D. Additionally, FGF23 levels can increase for at least three months after a large bolus dose, which also contributes to the suppression of vitamin D activation1.
This is the 9th of 30 COVID-19 RCTs for vitamin D, which collectively show efficacy with p=0.0000032.
This is the 58th of 122 COVID-19 controlled studies for vitamin D, which collectively show efficacy with p<0.0000000001 (1 in 587 sextillion).
This study is excluded in the after exclusion results of meta analysis: very late stage study using cholecalciferol instead of calcifediol or calcitriol.

The effect of supplementation with vitamins A, B, C, D, and E on disease severity and inflammatory responses in patients with COVID-19: a randomized clinical trial

Background and objective: Because of the effect of vitamins on modulating the immune system function, we have evaluated the effect of supplementation with vitamins A, B, C, D, and E in ICU-admitted patients with COVID-19. Methods: This study was a randomized and single-blinded clinical trial in which 60 subjects were randomly assigned to two groups. The intervention group (n=30) received vitamins, and the control group did not receive any vitamin or placebo. The intervention was included 25,000 IU daily of vitamins A, 600,000 IU once during the study of D, 300 IU twice daily of E, 500 mg four times daily of C, and one amp daily of B complex for 7 days. At baseline and after the 7-day intervention, the serum levels of inflammatory markers, vitamins, and the SOFA score were assessed. In addition, the mortality rate and duration of hospitalization were evaluated after the intervention (IRCT registration number: IRCT20200319046819N1/registration date: 2020-04-04, https://www.irct.ir/trial/46838). Results: Significant changes were detected in serum levels of vitamins (p < 0.001 for all vitamins), ESR (p < 0.001), CRP (p = 0.001), IL6 (p = 0.003), TNF-a (p = 0.001), and SOFA score (p < 0.001) after intervention compared with the control group. The effect of vitamins on the mortality rate was not statistically significant (p=0.112). The prolonged hospitalization rate to more than 7 days was significantly lower in the intervention group than the control group (p=0.001). Regarding the effect size, there was a significant and inverse association between receiving the intervention and prolonged hospitalization (OR = 0.135, 95% CI 0.038-0.481; p=0.002); however, after adjusting for confounders, it was not significant (OR=0.402, 95% CI 0.086-1.883; p=0.247).
