Probiotics & Early Microbial Contact in Preterm Neonates

Status Recruiting

Clinical Trial Summary

Probiotics are live microbes which, when administered in sufficient amounts, confer a health benefit to the host. According to recent clinical trials, administration of probiotics to very low birth weight infants significantly reduces overall mortality and risk of necrotizing enterocolitis, a devastating inflammatory intestinal disease. The investigators have previously demonstrated that administering probiotics to the lactating mother enhances the immunoprotective properties of breast milk. Despite the promising data, the optimal probiotic intervention is yet to be established. The mechanisms by which probiotics exert their effects remain largely unknown.

This research project is based on the notion that modulation of early microbial contact by probiotics may provide a safe and effective means to improve the health of preterm infants. In particular, the investigators hypothesize that the protective potential of probiotics may be enhanced via breast milk by administering probiotics to the lactating mother. All of the potentially beneficial effects of probiotic bacteria are strain-specific and therefore preliminary laboratory and clinical research with regard to different physiological targets of probiotic intervention should be carried out to guide the design of large-scale clinical trials aiming show clinical efficacy and establish clinical practice. The purpose of this research project is to identify targets for probiotic therapy in premature neonates and to provide insight into the optimal probiotic strains and administration protocol the clinical efficacy of which will subsequently be tested in a randomized controlled trial.

The specific aims of the project are:

1. To determine the effect of maternal consumption of probiotics during lactation on immunomodulatory properties of breast milk in mothers of premature infants. Concentrations of immunomodulatory factors and microbiological properties of breast milk will be measured.

2. To investigate the impact of different probiotic administration protocols on gut microbiota composition in preterm infants. In particular, the issue whether maternal probiotic consumption instead or in addition to probiotics administered to the infant is effective will be elucidated. Different potential probiotic strains will be assessed.

3. To elucidate the impact probiotic bacteria administered to the lactating mother and/or directly to the infant on gut immunophysiology in preterm infants.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
