About this study

Official title: A Randomized Controlled Trial on the Effect of 400 vs. 800 IU of Vitamin D on T Regulatory Cells in Preterm Infants

This study evaluate the effect of two different doses of vitamin D on T-regulatory cells in preterm infants. Half of the subjects receives 400 IU vitamin D and the other half receives 800 IU vitamin D.

Read the detailed description

Vitamin D, in addition to its bone mineralization effect, is an immune- modulatory agent. Fetal and premature cellular immunity are generally delayed. Whether vitamin D can enhance cellular immunity by increasing T regulatory cells is unknown. The effect of two different doses of vitamin D; 400 IU and 800 IU will be studied.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change in The Number of T Regulatory Cells

    Flow cytometry assessment of CD4+ , CD25+ with expression of FOXP3 will be used to identify T Regulatory cells

    Measured: At 1 week (compared to baseline)

  2. Percent Change in The Number of T Regulatory Cells

    Flow cytometry assessment of CD4+ , CD25+ with expression of FOXP3 will be used to identify T Regulatory cells

    Measured: At 4 weeks (compared to baseline)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vitamin D in people with Prematurity and Immune Defect, run by Cairo University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Percent Change in The Number of T Regulatory Cells (time frame: At 1 week (compared to baseline)). 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 NCT03793309, 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 7 Jan 2019.
