The use of hydrolysates in allergy prevention programmes

Area of Science:

• Allergy and immunology
• Pediatric medicine
• Nutritional science

Background:

• Atopic disease development is multifactorial, influenced by both genetic and environmental factors.
• Existing atopy prevention trials suggest antigen-specific prevention, particularly cow's milk protein elimination for high-risk infants.
• The long-term efficacy and mechanisms of early dietary interventions remain under investigation.

Purpose of the Study:

• To evaluate the five-year follow-up data of an atopy prevention program utilizing a partial hydrolysate formula.
• To investigate the role of early introduction of cow's milk proteins in tolerance development.
• To compare the potential effectiveness of partial versus high-degree hydrolysates in allergy prevention.

Main Methods:

• Follow-up data collection over five years for infants enrolled in a prevention program.
• Use of a partial hydrolysate formula in the feeding of high-risk infants.
• Analysis of the incidence and severity of atopic manifestations.

Main Results:

• Five-year follow-up data from a partial hydrolysate prevention program are presented.
• The study acknowledges the transient nature of cow's milk protein allergy in many infants.
• Uncertainty remains regarding the optimal degree of protein hydrolysis for tolerance induction and prevention efficacy.

Conclusions:

• Antigen-specific prevention, like cow's milk protein elimination, appears effective in reducing allergy incidence.
• The relevance of early tolerance induction to cow's milk proteins requires further clarification.
• Further research is needed to determine the optimal type of hydrolysate for effective atopy prevention.
