Brief summary
The goal of this randomized non-pharmacological Intervention study is to evaluate the effects of probiotic supplements (Bifidobacterium breve M-16V, Bifidobacterium lactis HN019, Lactobacillus rhamnosus HN001) on children affected by upper respiratory tract infections. The main questions it aims to answer are: * probiotic formulation can reduce intensity and duration of fever in children affected by upper respiratory tract infections * probiotic formulation can influence the gut microbiota composition in children affected by upper respiratory tract infections Participants will be asked to take probiotic supplements or placebo for 14 days and to collect three fecal samples: before probiotic supplementation (T0), 14 days after probiotic supplementation (T1), and 12 months after the enrollment (T2).
Interventions
* Stick: Bifidobacterium breve M-16V, Bifidobacterium lactis HN019, Lactobacillus rhamnosus HN001 + Maltodestrins * Drops: Bifidobacterium breve M-16V, Bifidobacterium lactis HN019, Lactobacillus rhamnosus HN001 + Medium chain triglycerides, vegetable fats, emulsifier, and maltodextrin.
* Drops: Medium Chain Triglycerides, vegetal oil, E471, and maltodextrin * Stick: Maltodextrin.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mean change in gut microbial composition by measuring gut microbiota characterization in fecal samples | 1 year | To assess the effects of a probiotic supplement compared to a placebo on gut microbiota characteristics at baseline, 14 days and 12 months by generation Sequencing, real-time PCR, and typing PCR |
| Gastrointestinal symptoms | Approximatively 7 days | Evaluation of the gastrointestinal symptoms by interview |
| Adverse events | Approximatively 15 days | Evaluation of differences in clinical effects in subjects with or without antibiotics collected by interview |
