Baseline Vitamin D Deficiency and COVID-19 Disease Severity
An observational study of Vitamin D Deficiency and Covid19, run by Parkview Medical Center at 1 site in United States.
Trial summary
It is known that vitamin D has been found to decrease incidence of viral respiratory infections, as well as have effects on multiple cytokines involved in immunomodulation and the bradykinin/renin-angiotensin system. Read more about this study

About this study
Official title: Baseline Vitamin D Deficiency and COVID-19 Disease Severity/Need for Escalation of Care
It is known that vitamin D has been found to decrease incidence of viral respiratory infections, as well as have effects on multiple cytokines involved in immunomodulation and the bradykinin/renin-angiotensin system.
Recently, data was released showing a correlation between baseline vitamin D deficiency status and increased risk of contracting COVID-19.
Read more
Separate analysis shows that many of the deleterious effects of COVID-19 may be due to the bradykinin/RAS system, and that vitamin D is one plausible treatment option to modulate these effects.
Studies are currently ongoing to determine if vitamin D supplementation of those hospitalized with COVID-19 has a beneficial effect on patient outcomes.
Healthcare resources have been strained during the pandemic in areas of heavy caseload. It is possible that those with concurrent vitamin D deficiency and COVID positivity have an increased need for escalation of care. A small study has been conducted in this area, but was limited by small number of subjects.

Abstract: It is known that vitamin D has been found to decrease incidence of viral respiratory infections, as well as have effects on multiple cytokines involved in immunomodulation and the bradykinin/renin-angiotensin system. Recently, data was released showing a correlation between baseline vitamin D deficiency status and increased risk of contracting COVID-19. Separate analysis shows that many of the deleterious effects of COVID-19 may be due to the bradykinin/RAS system, and that vitamin D is one plausible treatment option to modulate these effects. Studies are currently ongoing to determine if vitamin D supplementation of those hospitalized with COVID-19 has a beneficial effect on patient outcomes.
Objective: To determine if those hospitalized with COVID-19 with baseline vitamin D deficiency, have worse outcomes during their stay than those who are not vitamin D deficient at baseline.
Design, Setting, and Participants: This is a retrospective cohort study at an urban academic medical center which included patients with a 25-hydroxycholecalciferol level measured within one year before being tested for COVID-19 and hospitalized from March 9th to September 7th, 2020.
Exposures: Vitamin D deficiency was defined by the last measurement of 25-hydroxycholecalciferol less than 20 ng/mL before COVID testing (within one year).
Main Outcomes and Measures: The primary outcomes investigated include length of stay, need for supplemental oxygen, ICU admission, need for invasive life support (mechanical ventilation, vasopressors, dialysis), and discharge status (discharged alive vs. death).

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
LOS duration in days (time frame: 3/9-9/7 2020). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04628000, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2022; AzTrials last refreshed its copy on 6 Nov 2026.
