The objective of this study is to determine for previously healthy children who present to a Canadian Emergency Department (ED) with acute gastroenteritis (infection or irritation of the digestive tract); if compared with placebo, the administration of a probiotic agent (Lacidofil) will result in a significantly lower proportion of children developing moderate to severe disease over the subsequent 2 weeks and will not be associated with a significantly greater occurrence of side effects.

Primary Outcome Measures:
  • Development of moderate to severe disease in the 2 weeks after the index visit [ Time Frame: Measured daily for 14 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Duration of Diarrhea [ Time Frame: Daily for 14 days ] [ Designated as safety issue: No ]
  • Duration of Vomiting [ Time Frame: Daily for 14 days ] [ Designated as safety issue: No ]
  • Return visits for unscheduled care to a health care provider related to vomiting, diarrhea, dehydration, fever, or fluid refusal, within two weeks [ Time Frame: Daily for 14 days ] [ Designated as safety issue: No ]
  • Work and Daycare Absenteeism [ Time Frame: Daily for 14 days ] [ Designated as safety issue: No ]

Estimated Enrollment: 886
Study Start Date: October 2013
Estimated Study Completion Date: July 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Lacidofil
Lacidofil sachet containing active ingredients
Drug: Lacidofil
All patients in this arm of the study will take 1 sachet twice daily for 5 days. Each sachet will contain a minimum of 4 billion colony-forming units (CFU) of Lactobacillus rhamnosus Rosell-11 (95%) and L. helveticus Rosell-52 (5%). The total weight of all ingredients is 1 gm. Doses should be ideally separated by 12 hours (minimum of 8 hours) and taken within 30 minutes of food/drink. If the child vomits within 15 minutes of medication administration (initial or subsequent dose), the dose will be repeated. Total daily dose = 8 billion CFU x 5 days.
Placebo Comparator: Placebo
Placebo sachet containing inactive ingredients
Drug: Placebo
All patients in this arm of the study will take 1 sachet containing inactive ingredients (maltodextrin, magnesium stearate, and ascorbic acid) twice daily for 5 days. Doses should be ideally separated by 12 hours (minimum of 8 hours) and taken within 30 minutes of food/drink. If the child vomits within 15 minutes of medication administration (initial or subsequent dose), the dose will be repeated. Total of 2 sachets per day for 5 days.

Detailed Description:

The burden of acute gastroenteritis (AGE) on children and their families continues to be enormous. It accounts for 1.7 million pediatric emergency department (ED) visits annually in the United States and nearly 240,000 in Canada. Children often suffer from prolonged and severe illness; amongst hospitalized Canadian children, 19% have clinical sepsis, 7% seizures and 4% require intensive care unit admission.3 In a study that we conducted at 11 Canadian EDs, 51% of children experienced moderate to severe disease. Parents rate such episodes as being equivalent to a 10 day admission (moderate) and persistent moderate hearing loss (severe). The burden is augmented by the 50% household transmission rate2, 6 and 42% prolonged work absenteeism rate. Apart from supportive care, health-care providers have little to offer to relieve suffering.

Probiotics, which are defined as viable microbial preparations that have a beneficial effect on the health of the host, represent a rapidly expanding field. While they are available as over-the-counter products, according to the National Institutes of Health, the Food and Drug Administration has not yet approved a single agent for any health claims. Further, a 2012 meta-analysis concluded that there is limited data to support their indications and no published pediatric gastroenteritis trials reported on side effects. Thus, understanding the benefits and side effects of probiotics is crucial before widespread use can be endorsed. Although probiotic clinical trials have been performed, only one (still unpublished) has been ED based. Most studies to date have been significantly flawed and guidelines do NOT endorse their use stating that well-controlled human trials are needed. Consequently, we and others have found that they are rarely used in clinical practice. Reasons cited include (1) questionable clinical meaning to the outcomes evaluated thus far; (2) absence of studies in the appropriate patient population, and (3) a lack of confidence in the quality of probiotic agents studied.

This study will address (1) the needs of the medical community, which is aware of the widening gap between the number of important pediatric and adult trials and (2) the interest of caregivers in "probiotics" - 71% are aware of the term; 31% believe they may be beneficial in children with diarrhea, and > 90% would administer a probiotic if it could make their child better. Furthermore, our pilot study has provided promising preliminary data and has proven the feasibility of our methods. Thus we are poised to conduct a randomized controlled trial (RCT)that will definitively determine if meaningful benefits are derived from probiotic use and will provide critical information regarding their mechanism of action. This information will impact on practice, the burden of disease, and ensure that children receive the best care possible. The results of our proposed RCT will enable guidelines to either clearly endorse or recommend against the routine use of a probiotic agent in children with Acute Gastroenteritis.
