NCT05840588

Brief Summary

Amoxicillin or Amoxicillin/Clavulanic acid antibiotic therapy has been shown to be associated with disrupting the microbiota population particularly Bifidobacterium, which may have further GI clinical implications. The present randomized clinical trial is aimed to assess if probiotic Bifidobacterium breve PRL2020 (Brevicillin®) can help modulate the Bifidobacterium population and its clinical implications after antibiotic Amoxicillin or Amoxicillin/Clavulanic acid antibiotic therapy.

Outcome Measures

Primary Outcomes (2)

  • Incidence of antibiotic-associated diarrhea (AAD)

    Assessment of diarrhea occurring during antibiotic treatment with amoxicillin or amoxicillin/clavulanic acid. AAD will be counted starting from a single episode of diarrhea and not only after three or more episodes in one day, differing from the standard AAD definition.

    7-10 days (according to antibiotic prescription)

  • Incidence of gastrointestinal symptoms other than diarrhea

    Evaluation of gastrointestinal symptoms related to antibiotic therapy, including constipation, nausea, vomiting, abdominal cramps, bloating, and loss of appetite. These will be recorded daily by parents or legal guardians during the antibiotic course.

    7-10 days (according to antibiotic prescription)

Secondary Outcomes (3)

  • Change in gut microbiota diversity following probiotic and antibiotic treatment

    7-10 days (according to antibiotic prescription)

  • Tolerability of probiotic treatment

    7-10 days (according to antibiotic prescription)

  • Adherence to probiotic treatment

    7-10 days (according to antibiotic prescription)

Study Arms (2)

Probiotic Bifidobacterium breve PRL2020 (Brevicillin®)

EXPERIMENTAL

Patients in this arm will receive Probiotic Bifidobacterium breve PRL2020 (Brevicillin®) (20 billion CFU) 2 sticks/day for 7-10 days (according to antibiotic prescription)in addition to the antibiotic Amoxicillin or Amoxicillin/Clavulanic acid (antibiotic doses: 2-3/day according to physician prescription).

Drug: Antibiotic TreatmentDietary Supplement: Probiotic Bifidobacterium breve PRL2020 (Brevicillin®) treatment

Control

ACTIVE COMPARATOR

Patients in this arm will receive only antibiotic Amoxicillin or Amoxicillin/Clavulanic acid.
