Insights

Elevated S-motilin levels in infants with colic suggest gastrointestinal changes occur before symptoms appear. This finding offers early insights into infantile colic development.

Area of Science:

  • Gastroenterology
  • Neonatology
  • Pediatric Research

Background:

  • Infantile colic affects approximately 17.4% of infants.
  • The exact causes of infantile colic remain incompletely understood.
  • Early identification of contributing factors is crucial for infant well-being.

Purpose of the Study:

  • To investigate the role of S-motilin in the development of infantile colic.
  • To determine if elevated S-motilin levels precede the onset of colic symptoms.
  • To compare S-motilin levels in formula-fed and breast-fed infants with and without colic.

Main Methods:

  • Prospective study of 219 infants from birth to 12 weeks.
  • S-motilin levels measured in 78 infants (19 with colic, 59 without) at birth, 1 day, 6 weeks, and 12 weeks.
  • Comparison of S-motilin levels between infants with and without colic, stratified by feeding type.

Main Results:

  • Infants who developed colic showed significantly higher S-motilin levels in cord blood and at 1 day, 6 weeks, and 12 weeks of age.
  • Both formula-fed and breast-fed infants with colic exhibited higher basal motilin levels compared to controls at specific time points.
  • Elevated S-motilin was observed from the first day of life in infants who later developed colic.

Conclusions:

  • Raised S-motilin levels from birth may indicate early gastrointestinal alterations in infants who develop colic.
  • Motilin's role warrants further investigation as a potential early biomarker for infantile colic.
  • These findings suggest a potential biological basis for colic appearing very early in infancy.
