Prevention of atopic disease in "at-risk newborns" by prolonged breast-feeding

Area of Science:

• Pediatrics
• Immunology
• Allergology

Background:

• The link between breastfeeding and reduced risk of atopic disease (AD) is supported by prospective studies.
• However, retrospective studies have shown conflicting results regarding breastfeeding's protective effects.
• Infants with a hereditary predisposition to allergies are a key population for studying AD prevention.

Purpose of the Study:

• To evaluate the prophylactic effect of prolonged breastfeeding on the development of atopic disease (AD) in newborns at hereditary risk.
• To investigate the impact of a strict maternal dietary avoidance regimen alongside breastfeeding.
• To explore potential mechanisms underlying breastfeeding's protection against atopy.

Main Methods:

• A study involving 101 newborns identified as having a hereditary risk for allergic disease.
• Inclusion of a strict dietary avoidance regimen for nursing mothers throughout the study period.
• Monitoring the development of atopic disease (AD) in the infants over the study duration.

Main Results:

• Breastfeeding demonstrated a prophylactic effect in preventing the development of atopic disease (AD) in at-risk infants.
• Supplementing breastfeeding with soy milk also showed a protective effect against AD.
• The findings suggest a significant protective role for breastfeeding in this cohort.

Conclusions:

• Prolonged breastfeeding, including supplementation with soy milk, offers a protective effect against atopic disease (AD) in high-risk infants.
• The study reinforces the importance of breastfeeding for allergy prevention in predisposed infants.
• Further discussion is warranted regarding the specific mechanisms through which breastfeeding confers protection from atopy.
