NCT04836013

Brief Summary

This is a prospective multicenter pediatric double-blind, randomized placebo-controlled, parallel group clinical trial intended to evaluate the efficacy, safety and tolerability of a combined probiotic (LGG and L. reuteri LMG P-27481) in the prevention of antibiotic associated diarrhea and gastrointestinal symptoms in hospitalised children treated with antibiotics for proven or suspected bacterial infection.

Outcome Measures

Primary Outcomes (1)

  • Incidence of antibiotic-associated diarrhea, defined as episodes of otherwise unexplained diarrhea (≥3 loose or liquid stools per day with negative viral and bacterial stool tests), recorded by instructed parents in a structured daily diary.

    Both Intention to treat (ITT) and Multivariate linear regression models analysis taking into account age, sex, mode of antibiotic delivery, and the kind of antibiotics and comparison between the two groups will be performed.The relative risk (RR), 95% confidence interval (CI), and number needed to treat (NNT) will also be calculated. The difference between study groups will be considered significant when P-value \<0.05 or when the 95% CI for RR will not exceed 1.0.

    From the second day after starting antibiotic treatment to 2 weeks after stopping antibiotics

Secondary Outcomes (1)

  • Number of children with episodes of infective diarrhea; dehydration (by Vesikary scale), fever, abdominal pain, vomiting and constipation (by Bristol stool chart); general well being (by 1-10 scale) as assessed by patient's record form.

    6 months from enrolling

Other Outcomes (2)

  • Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    From enrolling to all the period of intervention (1 month)

  • Number of participants with abnormal fecal inflammatory markers (calprotectin, lactoferrine, IgA, IL10 and TNF-α) and urine metabolomic profile

    The additional stool and urine sample will be collected at recruitment, after 1 month and after 6 months from enrollment.

Study Arms (2)
