Study summary

Randomized study to determine the effect of a commercialized combination of 2 probiotic strains (Bifidobacterium Longum and Pediococcus pentosaceus) and the impact of feeding type in babies diagnosed with colic under Roma IV criteria when administered for 21 days.

Read the detailed description

Randomized, single-blind, interventional study with two parallel groups to determine the effect of two different commercialized probiotic products (Lactobacillus reuteri or a combination of two different strains (Bifidobacterium longum and Pediococcus pentosaceus)) and the impact of feeding type in babies diagnosed with colic under Roma IV criteria. Infants meeting selection criteria are randomized 1:1 and stratified according to the type of feeding (breastfed or formula).

Probiotics are administered once a day (5 drops) for 21 days. Parents must document clinical parameters during this 21 days. This parameters include colic-related symptoms, other functional gastrointestinal disorders symptoms, parental anxiety and adverse events.

Moreoever, stool samples are collected to determine intestinal microbiota and calprotectin levels.

What researchers measure

Primary outcomes

  1. Duration of crying and fussing

    Change on daily crying and fussing minutes measured through Barr ( Barr et al., 1988).validated crying and fussing scale. The Barr scale consists of a 24 hours dairy where parents paint number of hours crying and fussing every day. Results show the number of hours of crying and fussing per day.

    Time frame: 21 days

  2. Percent of responders

    Percent of subjects whose change in crying time is equal or larger than 50% from baseline

    Time frame: 7, 14, 21 days

Secondary outcomes

  1. Number of regurgitations

    Change in daily number of regurgitations

    Time frame: 21 days

  2. Bowel movements

    Change in daily number of bowel movements

    Time frame: 21 days

  3. Food intake

    Frequency of food intake

    Time frame: 21 days

  4. Parent's anxiety and depression

    Change in parent's anxiety and depression score measured through Hospital Anxiety and Depression Scale (HADS). The HADS questionnaire has 7 items each for depression and anxiety subscales. Scoring for each item ranges from zero to three, with three denoting highest anxiety or depression level. A total subscale score of \>8 points out of a possible 21 denotes considerable symptoms of anxiety or depression.

    Time frame: baseline, day 21

  5. Fecal microbiome

    Changes on fecal microbiome evaluated by RNA ribosomal 16S genes analysis

    Time frame: baseline, day 21

  6. Fecal calprotectin

    Change on calprotectin in feces

    Time frame: baseline, day 21

  7. Adverse events

    Frequency of adverse events reported on dairy report form after randomization and until day 21

    Time frame: 21 days
