About this study

Official title: Efficacy of a Prebiotic and Probiotic Combination in Preterm Infants

The purpose of this study is to see how oral preparations containing both probiotics and prebiotics impact the growth, bacterial colonization of the intestines, and fecal short chain fatty acid content in premature infants. Our hypothesis is that short term growth will be improved, the stool will have more healthy bacteria, and the fecal short chain fatty acid content will increase in the babies who receive the probiotic/prebiotic combinations compared to control groups.

Read the detailed description

Premature infants are at risk for a devastating infection of the intestines due to the immaturity of their intestines and immune system. Probiotics are bacteria with healthful qualities that are taken by mouth to improve the number of healthy bacteria in the intestines. Probiotics have been shown in several studies outside the U.S. to decrease the risk of serious intestinal infection and in one small study to improve the rate of weight gain in premature infants. Prebiotics are food supplements that stimulate the growth of healthy bacteria and suppress the growth of unhealthy bacteria. Prebiotics have been shown to improve the numbers of healthy bacteria in the stool of premature babies. Our study is designed to compare two over the counter probiotic/prebiotic combinations to each other and to a control group. Infants less than 35 weeks with a birthweight of 750-2000 gm are eligible and must be enrolled in the study within the first week of life. The babies are randomly assigned to either a control group (no probiotic/prebiotic, just a placebo), a group which receives Culturelle (Lactobacillus rhamnosus GG plus fructo-oligosaccharide, ConAgra), or a group which receives ProBioPlus (three strains of Bifidobacteria plus Lactobacillus acidophilus plus fructo-oligosaccharide, UAS Laboratories). The babies receive the study product by mouth twice daily for 28 days or until discharge (whichever comes first). Weekly measurements (weight, length, head size) and stool cultures are performed. Clinical progress is closely monitored and any episodes of infection are recorded.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ProBioPlusDietary supplement

    ProBioPlus is advertised as containing Lactobacillus acidophilus, Bifidobacterium longum, Bifidobacterium infantis, and Bifidobacterium bifidum plus inulin. The dose given was 5 x 10e8 twice daily.

  • CulturelleDietary supplement

    Culturelle is advertised as containing Lactobacillus rhamnosus GG. The dose was 5 x 10e8 twice daily.

  • PlaceboOther

    A dilute preparation of pregestimil powder formulated to have a similar appearance to the probiotic products

What is being measured

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

  1. Weight Gain

    Weight at five weeks minus birth weight

    Measured: 5 weeks

Secondary outcomes (2)
  1. Stool Colonization With Bifidobacteria

    Using standard culture techniques, we measured how many of the first 11 infants in each arm of the study grew bifidobacteria in their feces after four weeks of treatment.

    Measured: 4 weeks

  2. Stool Short Chain Butyric Acid Content

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing ProBioPlus and Culturelle in people with Premature Infants and Stool Bacterial Composition, run by University of California, Davis at 1 site in United States.

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 3 inclusion and 1 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 28 Jan 2010. 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 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 28 Jan 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Weight Gain (time frame: 5 weeks). 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 NCT00282113, which also lists 1 linked publication.

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 28 Jan 2010; AzTrials last refreshed its copy on 7 Nov 2026.
