This application a phase II clinical trial to address the possible active mechanisms of probiotics and to obtain preliminary efficacy and safety data after the administration of a probiotic, Lactobacillus reuteri a population of premature infants.

The hypothesis is that the exogenous supplementation Lactobacillus reuteri to premature infants will lead to clinical beneficial effects by modifying their intestinal microbiota and enhancing their intestinal immunological response.

Primary Outcome Measures:
  • Time to reach full feeds [ Time Frame: First 40 days after birth ] [ Designated as safety issue: No ]
    Days to reach full feeds from the day feeds are started

Secondary Outcome Measures:
  • Intestinal colonization [ Time Frame: 0-6 months after birth ] [ Designated as safety issue: No ]
    PCR quantification of lactobacillus reuteri in the stools

  • Intestinal immunological response [ Time Frame: 0-6 months ] [ Designated as safety issue: No ]
    Quantification immunological markers in the stools

Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: probiotic group
Lactobacillus reuteri will be given at a dose of 1x108 colony forming units (CFU)/day
Dietary Supplement: Lactobacillus reuteri
Lactobacillus reuteri DSM will be given at a dose of 1x108 colony forming units (CFU)/day
Placebo Comparator: Placebo
The placebo consists of an identical formulation except that the L. reuteri is not present.
Other: Placebo
The placebo consists of an identical formulation except that the L. reuteri is not present.

Detailed Description:

The primary outcome "days to achieve full feeds" will be measure during the the first month of life Secondary outcomes will be measured at baseline (before intervention), 3 weeks after intervention, once intervention discontinued and at 6 months of live
