简要总结
This is a single-center, double-blind, randomized controlled trial, with parallel groups and reference group. The aim of the study was to investigate whether feed a fermented formula milk leads to an increase of anti-microbial peptides such as catelecidine, alpha and beta defensins and secretory-IgA, compared to feed a standard formula (Plasmon Primigiorni), according to mode of delivery. Breastfed infants were the reference group.
详细描述
The microbiota plays an important role in modulating the development of the immune system, making decisive the interrelation that between nutrition, microbiota and immune cells to modulate long-term health outcomes.
The type of feeding, especially breastfeeding, and the type of delivery are factors that can contribute to the development of the microbiota. Specifically, the exclusive breastfeeding promotes the development of bifidobacteria that promotes protection against potential infections and the development of the immune system.
In recent years it was improved the biological effects of formula milk, that represent the substitutes of breast milk when this is not available or if there are contraindications to breastfeeding. Functional foods derived from fermentation of cow's milk with probiotic strains have been proposed for the prevention of infectious diseases of the child. Recently, in a monocentric double-blind prospective study, the efficacy of fermented cow's milk with Lactobacillus paracasei CBA L74 was evaluated in the prevention of common winter infections in children aged between 12 and 48 months. In this study, children treated with fermented milk had a lower incidence of respiratory and gastrointestinal tract infections compared to the control group. This effect was associated with a significant stimulation of innate immunity (α- and β-defensin, LL-37) and acquired (secretory IgA) and to a modulation of composition and function of the intestinal microbiota characterized by a significant increase in strains producing butyric acid (Firmicutes phyla). The nutritional intervention was very well accepted by the children and no adverse events were observed.
Primary objectives of this study were:
To evaluate whether the feeding with a fermented formulated milk determines an increase in anti-microbial peptides such as catelecidine, alpha and beta defensin and secretory IgA compared to the feed with the standard formula (Plasmon Primigiorni), with reference to the mother's milk.
