The study was aimed to evaluate whether vitamin D 3 supplementation could prevent respiratory worsening among hospitalized patients ehat COVID We designed a multicentre, randomized, double-blind, sequential, placebo-controlled clinical trial. The study was conducted in 17 second and third level hospitals, located in four provinces of Argentina, from 14 August to 22 June Participants were randomized to a single oral dose of IU of vitamin D 3 or matching placebo.

The primary outcome was the change in the respiratory Sepsis related Organ Failure Assessment score between baseline and the highest value recorded up to day 7. Secondary outcomes included the length of hospital stay; intensive care unit admission; and in-hospital mortality. Overall, participants were assigned to vitamin D 3 and to placebo mean [SD] age, There were no significant differences in the primary outcome between groups median [IQR] 0. Median [IQR] length of hospital stay was not significantly different between vitamin D 3 group 6.

There were no significant differences for intensive care effrct admissions 7. Among hospitalized patients with mild-to-moderate COVID and risk factors, a single high oral dose of vitamin D 3 as compared with placebo, did not prevent the respiratory worsening.

Vitamin D 3 supplementation has been proposed as a potential therapeutic strategy among patients with coronavirus disease COVID [ 1 wht 3 ]. Effects of vitamin D that tje favourably affect the outcomes of patients with infectious diseases include immunomodulatory and anti-inflammatory actions [ 4 — 6 ]. Acute respiratory disease syndrome is the main cause of death among hospitalized patients with COVID, and pro-inflammatory cytokines play a central pathogenic role [ 78 ].

Vitamin D reduces pro-inflammatory cytokines, increases those with anti-inflammatory actions, and also upregulates angiotensin-converting enzyme 2 receptor, which is the surface receptor for the entry of severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 to the alveolar epithelial cells [ 14 — 6910 ].

Furthermore, epidemiological studies have suggested a relationship between low vitamin D levels and COVID risk and adverse COVID outcomes, and an open-label pilot clinical trial suggested that supplementation with calcidiol significantly reduced the need for intensive care unit admissions [ 11 — 15 ]. However, a randomized clinical trial involving hospitalized patients with dhat to severe COVID showed no differences in length of hospital stay between oral supplementation with vitamin D 3 and placebo [ 16 ].

The objective of this randomized, double-blind, placebo-controlled clinical trial was to evaluate whether vitamin D 3 supplementation, given as a single high dose, could prevent respiratory worsening among hospitalized patients with mild-to-moderate COVID and risk factors for disease progression. The study was conducted in 17 hospitals located in four provinces of Argentina, and the local ethics committees of the participating institutions approved the protocol.

Written informed consent was obtained from all participants. The study was conducted in compliance with local regulations on research on human subjects, the Declaration of Helsinki and Good Clinical Practice guidelines. The study is registered in ClinicalTrials. Study protocol what is the placebo effect in ap stats been published elsewhere and is available in S1 File [ 21 ].

Psychosocial approach in social work practice sequential design consisted in an adaptative design with what is the placebo effect in ap stats stages. In the first stage, the study aimed to assess the effects of vitamin D on respiratory Sepsis related Organ Plscebo Assessment rSOFAand the second stage aimed to evaluate the effects of vitamin D on clinical events.

The protocol specified that the decision to proceed to the second stage would be made conditioned by the results of the primary endpoint analysis of the first stage. Age 45 or older was selected as inclusion criterion to ensure a baseline risk of respiratory worsening that allow to detect a therapeutic effect of the treatment, and to preserve the power of the study. Obesity was added as risk condition on October 13,since it fefect recognised as risk factor after the study begun.

After giving informed consent, patients were randomly assigned food science and nutrition courses in india a ratio to receive vitamin D 3 cholecalciferol or matching placebo, using an interactive web response system with permuted blocks of size 16 and Study interventions consisted in a single oral dose of IU of vitamin D 3 soft gel capsules 5 capsules of IU or matching placebo, given as soon as possible after randomization.

The study medication was packaged, labelled and shipped to the research sites by pharmacists from the Faculty of Pharmacy of Maimonides Ln. The pharmacy staff had no other role in the study, nor did they have contact with the sites. Follow-up was limited to hospitalization. During the first seven days blood pressure, heart rate, pulse stahs SpO2temperature, inspired fraction of oxygen FiO2respiratory rate, and clinical and adverse events were recorded.

In the cases that remained hospitalized for more than seven days, clinical and adverse events were recorded from day 8 until day 30, the discharge or death, whichever occurred first. The rSOFA was calculated by using the SpO2 instead the partial pressure of oxygen in arterial blood PaO2since was expected that most patients would not have arterial blood draws during hospitalization [ 23 — 25 ].

The rSOFA score was calculated with participant breathing room air, however, for participants with oxygen supplementation requirement and for whom treating physician judged inapproppriate to temporary interrupt, a guide for FiO2 estimation was provided to investigators S2 File. A sample of 16 participants from two study sites had blood samples draws for measurement of serum hydroxyvitamin D OH VitDat baseline and after 3 to 7 days after treatment.

The sample size was increased to patients to account for non-adherence with the protocol. Continuous state are expressed as means and SD in cases where normal distribution held, and medians and interquartile ranges otherwise. Categorical data are presented as frequencies and percentages. Differences in medians and the confidence intervals for these differences were generated using smoothed pkacebo with replicates.

Subgroup analyses were carried out using ordinal regression models with an interaction term of the subgroup indicator variable by treatment. For primary outcome, a sensitivity analysis using ordinal regression models was carried out, adjusting the estimated treatment effects for stratification variables site, diabetes and age. Also, a post-hoc adjusted analysis using a ordinal regression model to what is the placebo effect in ap stats for imbalances in COPD and asthma distribution was carried out.

Analyses were conducted using R version 4. As prespecified in the protocol, a blinded analysis was carried out after the recruitment of the first participants, the estimated sample size for the initial stage of the study. After a revision of the results, the Steering Committee decided to stop the recruitment and terminate the trial on 7 th July This decision was based on that the differences between groups, either on the primary outcome i.

The decision was communicated thereafter to the DSMB and to the local investigators. The local ethics committees of the participating institutions approved the study protocol before the start of the trial in each sites. Two hundred eighteen participants were included in the study between August and Juneat 17 research sites located in four provinces of Argentina S2 File.

One hundred fifteen and one hundred three patients were randomly assigned to vitamin D 3 and to placebo, respectively. Mean age was Risk factors included diabetes in 58 Median time from onset of the symptoms to admission was 7. Median time from hospital admission to randomization was 1. There were no significant differences between treatment groups in baseline characteristics Table 1.

Study medications were adequately tolerated and there were no ao of immediate adverse reactions after study capsules intake. Baseline measurements, were Post-treatment OH VitD levels were A change in the rSOFA up to day 7 was recorded in 65 participants Among participants in vitamin D3 group, 0. The median IQR of the change in What does dirty water mean between baseline and the lowest value recorded during the first 7 days was Median length of hospital stay was 6.

Overall, 20 9. There were no significant differences between groups in other secondary outcomes Table 2. Results for the primary outcome were consistent across all prespecified subgroups. Whaf were no significant interactions between subgroup indicators and treatment effects Fig 3. These analyses should be carefully interpreted since the number of ie in each subgroup is small. The analysis adjusting the estimated effects of treatment for stratification variables gave similar results to main analysis OR 0.

The results of a post-hoc analysis adjusting for the imbalance in the distribution of COPD or asthma between groups, were similar to main results OR 0. Overall, 45 serious adverse events among 29 participants were reported. There were no significant differences between groups in either the occurrence of at least one serious adverse event or in the incidence of specific events by effedt Table 3. The results of the present study show that a single, high, oral dose of vitamin D 3 among a non-selected population of patients with mild-to-moderate COVID did not prevent the respiratory worsening.

Also, there were no significant effects on the length of hospital stay or other outcomes. Furthermore, overall results were consistent across all pre-specified subgroups. Previous studies have suggested a role of vitamin D supplementation for the prevention of acute respiratory disease, particularly among individuals with low serum OH VitD levels [ 29 — 31 ]. Several mechanisms have been proposed for the potential beneficial effects of vitamin D among COVID patients, including the modulation of what is the placebo effect in ap stats response [ 179what is a strong correlation in math ].

Furthermore, previous studies have shown that low vitamin D levels are associated with higher SARS-Cov-2 infection risk, severity and mortality [ 11 — 1315 ]. Also, an open-label randomized controlled trial has found that the supplementation with oral calcifediol agent causation theory. However, a double-blind trial among moderate to severe COVID patients, showed that a single oral dose supplementation with IU of vitamin D 3 did not reduce what is the placebo effect in ap stats length of hospital stay [ 16 ].

The present study is xp line with these results and what is the placebo effect in ap stats them to mild-to-moderate COVID patients, and to other relevant outcomes i. The study used a single dose of IU of oral vitamin D 3 since it was previously demonstrated that this scheme rapidly increases plasma levels what is the placebo effect in ap stats OH VitD, and that achieved levels are maintained for at least 4 weeks, covering the period of highest what is the placebo effect in ap stats for respiratory worsening, with an adequate security profile [ 33 ].

Although, an increase in OH VitD plasma levels was achieved, there were no effects of treatment on the study outcomes. These results are consistent with th trial showing that there were no significant effects of id D 3 supplementation placebp an increase in plasma OH VitD, neither in all cohort nor in OH VitD deficient participants [ 16 ]. It has been hypothesized that a supplementation with a single high dose of vitamin D, although it serves to raise plasma what is the placebo effect in ap stats of OH VitD, does not improve the immune response, and that chronic supplementation, with daily or weekly doses of vitamin D would produce better clinical results instead [ 3034 ].

Perhaps, the stage of the disease at hospial admission in the present study was too late for treatment to express benefial effects, since vitamin D needs several days to stas the mechanisms immune, metabolics, antioxidant, endocrine leading to antiviral effects [ 20 ]. However, well-designed clinical trials are necessary to evaluate the effects of different regimens of vitamin D supplementation. Additionally, it is worthwhile that the baseline OH VitD plasma levels were higher than in other studies [ 111617 ]; these differences could be due to differences in populations studied and to the fact that in our study the OH VitD measurements were conducted mainly during the summer and early autumn, but the causes remain speculative [ 35 ].

Although results of vitamin D3 supplementation for treatment of patients with COVID could be theoretically modified whta the serum vitamin D status, with deficient populations obtaining the most benefits, this remains speculative. The strengths of this study include the double-blind, placebo-controlled design, the multicentre inclusion of participants with representation of a broad sociocultural background from the country, and the high adherence to study protocol and follow-up.

Rational use that respects this recommendation would generate savings in medication costs, and probably also for hospitalization, by avoiding prolonged hospital stay for the administration of the antibiotic itself, the generation of resistances and the prevention of complications.
