Abstract:
PURPOSE: The aim of this study was to compare the effects of breast milk (BM) feeding with those of maternal cow milk (CM) restriction and extensively hydrolyzed CM formula feeding on the duration of CM allergy as well as changes in specific immunoglobulin E (IgE) levels in infants with CM allergy. METHODS: Children diagnosed with CM allergy before 12 months age and BM fed were included retrospectively. CM allergy was diagnosed by CM specific IgE over 0.35 kU/L and 1) obvious clinical symptoms, 2) a suspicious history with positive provocation test, or 3) CM specific IgE over the 95% positive predictive value and subsequent documented report of clinical symptoms. The patients were classified into three groups by feeding regimen: BM group, extensively hydrolyzed formula (eHF) group, or mixed feeding (MF) group. Analysis of the groups regarding the duration of food allergy and changes in CM specific IgE was then performed. RESULTS: Forty-six children were included. Twenty-four children were in the BM group, 13 children were in the eHF group, and 9 children comprised the MF group. Thirteen patients reached tolerance. The means of the tolerance age were 69.7+/-5.4 months in the BM group, 36.6+/-4.6 months in the eHF group, and 38.2+/-7.9 months in the MF group. The survival curves of tolerance showed significant difference among the three groups (P=0.04). CM specific IgE levels measured at a second time period were 9.6 kU/L (interquartile range, 3.6-44.2) in the BM group, 2.0 kU/L (1.0-18.0) in the eHF group, and 4.8 kU/L (0.2-10.4) in the MF group (P=0.04). CONCLUSION: Feeding regimen influences the duration of CM allergy. Exclusively BM-fed children achieved tolerance later than eHF-fed children. Prospective and randomized controlled studies are required.
