About this study
Official title: Supplementation of Vitamin D in Preterm Infants- Monitored Therapy vs Standard Therapy. A Randomized Controlled Trial
The purpose of this study is to determine wheather the monitored vitamin D (vit D) therapy is safer and more effective than standard therapy in pretrem infants.
Read the detailed description
Vitamin D (vit D) deficiency is a risk factor of osteopenia of prematurity, which leads to rickets or decreased bone mass mineral density. Recently multiple studies have been published on vit D adjust biological functions. Dosage, safety and effectiveness of vitD supplementation in preterm infants still remains a controversial topic. We hypothesize that monitored supplementation of vit D is more effective and safer than standard therapy 500IU in preterm infants. The study will be carried out in 138 preterm infants, born at 24-32 week of gestational age (GA) at the Princess Anne's Hospital in Warsaw, Poland. We will determine if monitored supplementation of vit D decreases the incidence of vit D deficiency and/or overdosing at 40 week (GA). For secondary objective we shall assess if monitored therapy reduces the incidence of vit D deficiency and/or overdosing at 35, 52 week (GA), prevalence of osteopenia, low bone mass, nephrocalcinosis and nephrolithiasis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
monitored vit D supplementationDietary supplement
The vit D supplementation dose start from dose 500IU from 7th day of age and is modified based on vit D measurement at 4 week of age for infants born <30 GA, at 8 week of age for infants born <26 GA at 35+/-2 weeks PMA(postmenstrual age), +/-at 40+/-2 weeks PMA according to the protocol.
standard vit D supplementationDietary supplement
The vitamin D supplementation dose is 500IU from 7th day of age.

Questions about this trial
What is this clinical trial studying?
A study testing monitored vit D supplementation and standard vit D supplementation in people with Vitamin D Deficiency and Osteopenia, run by Princess Anna Mazowiecka Hospital, Warsaw, Poland at 1 site in Poland.
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 5 inclusion and 7 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 15 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. 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?
Number of Participants with D- deficiency or access (time frame: at 40 (+/-2 weeks) PMA (postmenstrual age)). The study lists 4 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 NCT03087149, which also lists 25 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 15 Feb 2021.
