Association between sites and severity of eczema and the onset of cow's milk and egg allergy in children.

ABSTRACT: BACKGROUND:Cow's milk allergy (CMA) and egg allergy (EA) are common and can reduce quality of life in children. Infantile eczema is a well-established risk factor for the onset of food allergy via transdermal sensitization; however, various types of infantile eczema have not yet been evaluated. Therefore, we assessed the association between CMA and EA and the sites and the severity of infantile eczema. METHODS:This retrospective study was based on data from patients aged 2-19 years with atopic disease who were treated between July 2015 and March 2019 in a pediatric allergy clinic in Japan. Data regarding the history of IgE-mediated symptoms, eczema in the first year of life, parental history of atopic diseases, and infantile nutrition were collected. RESULTS:A total of 289 patients were included in the study, of which 81 and 111 children had IgE-mediated CMA and EA, respectively. The rates of CMA and EA were higher in the children with infantile eczema than in those without (30% vs. 9% and 42% vs. 21%). The rate of CMA was also higher in children with eczema on the face. Significant differences were noted in the rate of CMA among children with facial eczema of exudation (adjusted odds ratio 2.398; P = 0.017) and papules (adjusted odds ratio 2.787; P = 0.008), using multivariate analysis. CONCLUSION:The rate of IgE-mediated CMA was high among children with atopic disease having severe facial eczema during infancy.

Project description:BackgroundIn case of cow's milk allergy (CMA), pediatric guidelines recommend for children the use of extensively hydrolyzed formulas (eHFs) as elimination diet. According to the American Academy of Pediatrics, the hypoallergenicity of each specific eHF should be tested in subjects with CMA.MethodsA prospective, multicenter trial was performed to assess the tolerance/hypoallergenicity of a thickened casein-based eHF (eHCF, Allernova AR®, United Pharmaceuticals, France) in infants aged <12 months with CMA proven by a double-blind placebo-controlled food challenge. Its efficacy, measured through allergy symptoms monitoring and Cow's Milk-related Symptom Score (CoMiSS) calculation, and safety were evaluated during a 4-month feeding period. Growth z-scores were computed based on WHO anthropometric data.ResultsThirty infants (mean age: 4.8 ± 3.0 months) with CMA proven by a DBPCFC tolerated the eHCF during the 4-month study. The CoMiSS, crying and regurgitation scores significantly decreased by 4.2 ± 4.0, 0.9 ±1.2 and 0.7 ± 1.1 respectively, after 14 days of feeding (p < 0.001). The Scoring Atopic Dermatitis index, of 33.2 ± 14.8 at inclusion in 9 patients, significantly decreased by 15.5 ± 6.7 and 21.1 ± 11.2, after 14 and 45 days of feeding, respectively (p < 0.001). The percentage of infants having normal stool consistency (soft or formed stools) significantly improved from 66.7 % (20/30) at inclusion to 90.0 % (27/30) after 14 days of feeding (p = 0.020). The growth z-scores, negative at study inclusion, significantly improved over the 4-month study. No adverse event was related to the eHCF.ConclusionThe thickened eHCF was tolerated by more than 90 % of included allergic infants with 95 % confidence interval and can therefore be considered as hypoallergenic in accordance with current guidelines. The improvement of growth indices and absence of related adverse events confirmed its safety. Results of this trial back the use of the tested thickened eHCF as an efficient and safe alternative in children with CMA.Trial registrationClinicalTrials.gov, number NCT02351531 , registered on 27 January 2015.
