About this study

Official title: Should Infants Receive High-dose Vitamin A Supplementation With BCG Vaccine at Birth in Developing Countries?

Two studies from Asia have suggested a beneficial effect of vitamin A supplementation given at birth. Hypotheses: Vitamin A supplementation administered at birth together with BCG vaccination is associated with a 30% reduction in infant mortality and morbidity during the first year of life in normal birth weight children in an African setting.

Read the detailed description

Vitamin A deficiency is common in low-income countries. Vitamin A supplementation to children above 6 months of age reduces all-cause mortality with 23 % to 30 %. Studies on vitamin A supplementation in infants younger than 6 months of age have reported inconsistent effects on mortality. Studies providing supplementation between 1 and 5 months of age have found no effect or even a negative effect. However, the only two studies of supplementation at birth, both conducted in Asia, showed substantial significant reductions in infant all-cause mortality.

The beneficial effect of neonatal vitamin A supplementation may be a result of correcting the congenital vitamin A deficiency resulting from maternal vitamin A deficiency. On the other hand, it has been speculated that the beneficial effect of vitamin A supplementation given at birth may in part be explained by a synergistic effect of vitamin A supplementation and BCG vaccination given at the time of birth.

The protective effect on mortality of vitamin A supplementation given at birth needs to be confirmed in an African population. Furthermore, none of the two previous studies have reported data on vaccination status of the included infants.

In this study, the effect on mortality and morbidity of given vitamin A supplementation simultaneously with BCG vaccination at birth to normal birth weight infants will be investigated in an African population. Furthermore, the effects of vitamin A supplementation will be evaluated with respect to effect on growth, the response to BCG vaccination, infant vitamin A status and infant cytokine profile. Furthermore the effect on specific diseases such as malaria, measles and rotavirus infections. The mechanisms behind the effects of vitamin A will be evaluated.

We will include 4,800 normal birth weight infants (> 2500 g) infants randomized to 50,000 IU of vitamin A or placebo given simultaneously with BCG vaccine. The study take place in Guinea-Bissau, West Africa. The study area consists of five districts in the capital of Guinea-Bissau. The Bandim Health Project has been working in the study area for almost 25 years, and a demographic surveillance system has been established and functioned for many years.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 0 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 Nov 2013. 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 Guinea-Bissau. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Mortality. 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 NCT00168597, which also lists 7 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 Nov 2013.
