Lactobacillus Reuteri DSM 17938 Versus Placebo in the Treatment of Infantile Colic

Infantile colic is one of the most commonly reported medical problems within the first three months of life causing appreciable distress for both parents and pediatricians. The reported incidence of infantile colic ranges from 3% to 28% in prospective studies and up to 40% in retrospective surveys.

The pathogenesis of infantile colic remains elusive despite decades of research. It appears that multiple independent origins might be involved: amongst them infant's difficult temperament, inadequate mother-infant communication or maternal anxiety, transient lactase deficiency, exposure to cow's milk, abnormal gastrointestinal function, maternal smoking during pregnancy or after delivery. Consequently, various treatment approaches have been tried to alleviate this condition.

Recent studies have suggested that changes of intestinal microflora of a newborn may play an important role in pathogenesis of infantile colic. Therefore, dietary supplementation with probiotics has been proposed for the improvement of this condition.
