Effect of a Dietary Supplement vs Low-dosage Product on Infant Gastrointestinal Discomfort and Colics

Randomized Double-blind Monocentric Clinical Trial on the Effect of a Dietary Supplement vs Low-dosage Product on Reduction of Infant Gastrointestinal Discomfort and Colics

The goal of this clinical trial is to verify whether a food supplement is effective in treating infantile colic of infants aged between 21 days and 9 months and the colonization ability of the gut microbiota by measuring faecal relative abundance of the gut microbiota probiotic treatment species.

The main outcomes are: - the mean number of crying episodes and the sleep duration - Relative abundance of the gut microbiota probiotic treatment species.

Infant colic, characterized by excessive crying/fussing for no apparent cause, is common and distressing to families.

The exact causes of infant colic are heterogeneous and not fully understood in detail, but some likely hypotheses point on factors such as gut dysmotility and food intolerance. Growing evidence suggests that the gut microbiota could be also involved in colics: a higher amount of Coliforms and a lower amount of Lactobacilli have been found in colicky infants compared to non-colicky subjects, and probiotic supplementation with Lactobacillus reuteri has been shown to be effective in treating the condition in some clinical trials of breastfed infants.

In the present study, the investigator performs a randomized controlled clinical trial aimed to verify whether a food supplement is effective in treating infantile colic of infants and colonization ability of the gut microbiota by measuring faecal relative abundance of the gut microbiota probiotic treatment species.

The product is a food supplement based on freeze-dried probiotics (Lactobacillus reuteri DSM 25175 and Lactobacillus acidophilus DSM 24936) and chamomile oleolite to promote the balance of the intestinal bacterial flora, on gastrointestinal discomfort in children aging 0-9 months.

Treatment consists of taking the product or the low-dosage product 7 drops x 2/die for a 30-days. A follow-up was made after 30 days wash out.

Infant colics are diagnosed with FLACC (Face, Legs, Activity, Cry, Consolability

• preverbal patient pain scale) and G4 Infant Colic Rome IV criteria, while relative abundance of the gut microbiota probiotic treatment species (L. reuteri and L. acidophilus) will be evaluated using quantitative PCR (Polymerase Chain Reaction), in order to identify the colonization ability of the study treatment (Fecal sample).
