Probiotic Bifidobacterium Breve PRL2020 in Oral Drops in Preventing Side Effects From Amoxicillin or Amoxicillin/Clavulanic Acid Antibiotic Use
Assessment of the Impact of an Amoxicillin/Clavulanic Acid-resistant Probiotic on the Reduction of AAD (Antibiotic-Associated Diarrhoea) in Children Treated With Amoxicillin/Clavulanic Acid or Amoxicillin: a Multicentre, Randomised, Placebo-controlled Clinical Trial.
This multicenter, randomized, double-blind, placebo-controlled clinical trial will evaluate the efficacy and safety of the probiotic Bifidobacterium breve PRL2020 (Brevicillin® gocce) in preventing gastrointestinal side effects associated with antibiotic therapy using amoxicillin or amoxicillin/clavulanic acid in pediatric patients aged 0-12 years. Participants will be randomized 1:1 to receive either the probiotic supplement or placebo during standard antibiotic treatment for 6-10 days, followed by a post-treatment observation period up to day 15 without probiotic or placebo administration. The primary objective is to assess the reduction in the incidence of antibiotic-associated diarrhea (AAD).

詳細な説明
Antibiotic therapy with amoxicillin or amoxicillin/clavulanic acid is widely prescribed in pediatric populations but is frequently associated with gastrointestinal adverse effects, particularly diarrhea. These effects are linked to disruption of the gut microbiota and a reduction in bifidobacterial populations. Bifidobacterium breve PRL2020 is a probiotic strain with demonstrated intrinsic, non-transferable resistance to these antibiotics and has been developed to mitigate antibiotic-induced dysbiosis.
This study is a multicenter, prospective, randomized, double-blind, placebo-controlled, non-profit trial conducted in pediatric centers across Italy. The study aims to evaluate the clinical efficacy and safety of Bifidobacterium breve PRL2020 in reducing the incidence and severity of antibiotic-associated diarrhea (AAD) in children receiving amoxicillin or amoxicillin/clavulanic acid.
A total of 1024 participants will be enrolled. Participants will be randomized 1:1 to receive either Brevicillin® gocce (5 drops 2-3 times daily, containing 5 billion CFU of B. breve PRL2020 per dose) or matching placebo only during antibiotic therapy (6-10 days). After completion of antibiotic treatment, participants will enter a follow-up period until day 15 without probiotic or placebo administration.
The primary outcome is the incidence of AAD, defined as ≥3 diarrheal episodes in one day during antibiotic treatment (Bristol Stool Scale 5-7).
Secondary outcomes include the incidence and duration of diarrhea, daily bowel movements, stool consistency, gastrointestinal and extra-intestinal symptoms (such as nausea, vomiting, abdominal pain), treatment compliance, and adverse events.

実験的:Brevicillin® gocce (Bifidobacterium breve PRL2020)
Participants will receive Brevicillin® gocce, a probiotic food supplement containing Bifidobacterium breve PRL2020 (LMG S-32458), alongside standard antibiotic therapy with amoxicillin or amoxicillin/clavulanic acid. Dosage and administration: 5 drops, 2-3 times per day (depending on antibiotic dosing schedule), administered during the antibiotic treatment period (6-10 days). After completion of antibiotic therapy, participants will enter a follow-up period until day 15 without probiotic administration. |
Brevicillin® gocce is a probiotic dietary supplement in oily drops containing the bacterial strain Bifidobacterium breve PRL2020 (LMG S-32458). Each 5-drop dose contains approximately 5 billion live cells. The supplement is administered orally 2-3 times per day, in parallel with antibiotic therapy (amoxicillin or amoxicillin/clavulanic acid), for 6-10 days only (during the antibiotic course). After completion of antibiotic therapy, participants enter a follow-up period until day 15 without probiotic administration. The product is manufactured by PharmExtracta S.p.A., Pontenure, Italy. |
|
プラセボコンパレーター:Placebo
Participants will receive a placebo formulation matched in appearance, packaging, and dosing schedule to Brevicillin® gocce, administered alongside standard antibiotic therapy with amoxicillin or amoxicillin/clavulanic acid. The placebo will be given at the same frequency (5 drops, 2-3 times per day) and duration as the experimental product during the antibiotic treatment period (6-10 days). After antibiotic completion, participants will enter a follow-up period until day 15 without placebo administration. |
The placebo is a formulation identical in appearance, packaging, and administration schedule to Brevicillin® gocce but without the Bifidobacterium breve PRL2020 strain. It is administered orally 2-3 times per day only during the antibiotic treatment period (6-10 days). After antibiotic completion, participants enter a follow-up period until day 15 without placebo administration. |
