Is this trial a fit for you?

Likely a good fit

Ideal participants are formula-fed infants ≤5 months old with diagnosed infant colic (Rome IV), with or without atopic dermatitis.

Probably not a fit

Some infants may not experience meaningful improvement or could have no difference compared with placebo.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Infants who are formula-fed and meet Rome IV criteria for colic, with or without atopic dermatitis, will receive either Bifidobacterium bifidum drops or a placebo for eight weeks. The trial compares the effect on average daily crying time and several secondary outcomes such as crying frequency, sleep quality, bowel movements, stool consistency, gut microbiota, SCFA levels, and SCORAD scores. It uses a randomized, placebo-controlled design to assess safety and efficacy in a young population. The probiotic preparation contains BFP19 and BFP29 strains delivered as Bifipral drops. Eligible participants are non-breastfed infants aged ≤5 months whose guardians provide informed consent.

Why it matters

Potential benefit: If successful, infants may experience shorter crying times and improved comfort, with potential benefits for sleep and digestion.

How similar studies have gone: Previous research in early-life probiotics suggests potential benefits for gut health and colic, but results vary and this study tests a specific B. bifidum formulation.
