Tolerability of a new amino acid-based formula for children with IgE-mediated cow's milk allergy.


ABSTRACT:

Background

Amino acid-based formula (AAF) is a relevant dietary strategy for paediatric patients affected by cow's milk allergy (CMA). The present study was designed to evaluate the hypoallergenicity of a new AAF in children with immunoglobulin (Ig)E-mediated CMA.

Methods

According to the criteria provided by the American Academy of Pediatrics Subcommittee on Nutrition and Allergic Diseases, we designed a prospective trial in CMA children (aged 1-36 months) aimed to demonstrate the hypoallergenicity of the new AAF in 90% of subjects with 95% confidence during the double-blind, placebo-controlled challenge (DBPCFC). A skin prick test (SPT) with the new AAF was also performed.

Results

Twenty-nine children [all Caucasian, 55.2% male, mean age (±SD) 16.9 ± 5.7 months] were enrolled. The SPT and the DBPCFC with the new AAF were negative in all study subjects.

Conclusions

The study results support the hypoallergenicity of the new AAF. This formula could be considered an additional dietary option for non-breastfed children affected by CMA.

Trial registration

The trial was registered in the ClinicalTrials.gov Protocol Registration System (ID number: NCT03909113 ).
