What this trial studies

This clinical trial aims to evaluate the effects of the probiotic B. lactis B94 on infants diagnosed with infantile colic. Participants will be randomly assigned to receive either the probiotic or a placebo for a duration of four weeks, following a one-week baseline period. The study will include three in-person visits and four phone calls to monitor progress and collect data on crying duration. The primary outcome is the reduction in crying time among those receiving the probiotic compared to the placebo group.

Who should consider this trial

Good fit: Ideal candidates are healthy infants aged 8 weeks or younger who are exclusively breastfeeding and meet the criteria for infantile colic.

Not a fit: Patients who are partially or fully formula-fed, or those with certain medical conditions such as gastroesophageal reflux disease, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive treatment option for reducing crying time in infants suffering from colic.

How similar studies have performed: Previous studies have shown promising results with probiotics in managing infantile colic, suggesting potential for success in this approach.
