Abstract
Background: Partially hydrolyzed cow's milk protein-based formula (pHF) possesses low allergenicity. Here, we investigate the safety and efficacy of oral immunotherapy using pHF for children with cow's milk protein allergy (CMPA). Objectives: A randomized, double-blind, controlled single-center trial was conducted to evaluate the efficacy and safety of pHF oral immunotherapy in children with CMPA. Methods: Participants were randomized into double-blind pHF-pHF and extensively hydrolyzed cow's milk protein-based formula (eHF)-pHF groups. During this phase, the pHF-pHF group received pHF and the eHF-pHF group received eHF. During the open phase, all participants received pHF. The primary end point was a change in thresholds between baseline and the end of the first phase. Secondary end points were changes in thresholds between baseline and the end of the second phase, and casein-specific immunoglobulin (Ig)E, IgG4, and basophil activation. Results: Twenty-five children, aged 1-9 years, were randomized into pHF-pHF and eHF-pHF groups. The threshold between baseline and the end of the first phase was significantly elevated in the pHF-pHF group (p = 0.048), but not in the eHF-pHF group. The threshold between other phases did not change significantly in either group. There were significant decreases in casein-specific IgE antibody levels between baseline and the second phase in the eHF-pHF group (p = 0.014). No participants suffered systemic allergic reactions requiring adrenaline or systemic corticosteroids after receiving the formulas. Conclusions: The results of this trial suggest that, in children with CMPA, tolerance to cow's milk might be safely enhanced by intake of pHF, relative to that of eHF.
