  Purpose

Randomized, doble blind, clinical, controlled trial aimed to investigate the role of Lactobacillus reuteri DSM 17938 in the prevention of gastrointestinal and respiratory tract infections in mexican children who attend day care centers.

Primary Outcome: The primary outcome will be "days with diarrhoea". Secondary Outcomes: a) Days with respiratory tract infections (RTI); b) Days of absences from day care centre; c) Days of antibiotic use; d) Days of medical office visits or emergency visits; and e) Direct and Indirect costs.

Methods: Prospective, randomized, double blind, placebo controlled trial to realize in 260 healthy term infants, born at term (≥36 weeks of gestation), 6 to 36 months old, who will be recruit from Child Care Centers in Mexico and randomly allocated to receive either 1 x 108 colony-forming units of Lactobacillus reuteri DSM 17938 or placebo, each day for 12 weeks, follow up for other additionally 12 weeks of observation. Days with respiratory tract infections (RTI); days of absences from day care centre; days of antibiotic use; days of medical office visits or emergency visits; and direct and Indirect costs will be compare between groups using bi-variate, multiple lineal regression analysis and cost-effectiveness analysis

Primary Outcome Measures:
  • days with diarrhoea [ Time Frame: January 2011 to June 2011 ]
    Diarrhoea is defined as 3 or more loose or watery stools within 24 hours with or without vomiting. Days with diarrhoea is defined as the total amount of days with diarrhoea since the beginning of the study products administration until the last visit occurs. If liquid or loose stools is present a notification shall be made to the principal investigator.


Secondary Outcome Measures:
  • Days with respiratory tract infections (RTI) [ Time Frame: January 2011 to June 2011 ]
    Total amount of days with any RTI (common cold, rhinitis, acute rhinosinusitis, otitis, pharyngitis, tonsillitis, laryngitis, traqueítis, bronchiolitis, pneumonia), reported since the beginning of the study products administration until the last visit occurs

  • Days of absences from day care centre [ Time Frame: January 2011 to June 2011 ]
    Total amount of days of absences from the day care centre during the study, secondary to the presence of a gastrointestinal episode or RTI, reported since the beginning of the study products administration until the last visit occurs

  • Days of antibiotic use [ Time Frame: January 2011 to June 2011 ]
    Total amount of days of antibiotic use during the study, secondary to the presence of a gastrointestinal episode or RTI, reported since the beginning of the study products administration until the last visit occur

  • Days of medical office visits or emergency visits [ Time Frame: January 2011 to June 2011 ]
    Total amount of medical office visits or emergency visits during the study, secondary to the presence of a gastrointestinal episode or RTI, reported since the beginning of the study products administration until the last visit occurs.

  • Direct and Indirect costs [ Time Frame: January 2011 to June 2011 ]
    Total amount of money spent by hospital or parents (or guardians) during the study and secondary to the presence of a gastrointestinal episode or RTI, reported since the beginning of the study products administration until the last visit occur


Estimated Enrollment: 269
Study Start Date: January 2011
Estimated Study Completion Date: June 2011
Estimated Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Lreuteri
Group of 130 infants allocated to receive L. reuteri DSM 17938 will be given at a dose of 5 drops containing 1x108 colony-forming units (CFU) once time per day in an oil formulation delivered from a drop bottle. In the active study product, freeze-dried L. reuteri is suspended in a mixture of pharmaceutical grade medium chain triglycerides and sunflower oil together with pharmaceutical grade silicon dioxide to give the product the correct rheological properties.
Dietary Supplement: Lreuteri
