PurposeThe clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies.MethodsThe study included children <10 years of age with signs and symptoms indicative of immediate-type food allergies. Serum total IgE level was measured, and ImmunoCAP analysis for food allergens was performed.ResultsThe mean age of the study subjects was 1.6±1.6 years (75 boys and 51 girls). Thirty-eight children (30.2%) were monosensitized and 88 children (69.8%) were polysensitized. Multivariate logistic regression analysis showed that the development of polysensitization to common food allergens was positively associated with a parental history of allergic rhinitis (adjusted odds ratio [aOR], 6.28; 95% confidence interval [CI], 1.78-22.13; P=0.004), season of birth (summer/fall) (aOR, 3.10; 95% CI, 1.10-8.79; P=0.033), and exclusive breastfeeding in the first 6 months of age (aOR, 3.51; 95% CI, 1.20-10.25; P=0.022).ConclusionWe found significant clinical differences between children with monosensitization and those with polysensitization to common food allergens and identified risk factors for the development of polysensitization in young children with immediate-type food allergies. Clinicians should consider these clinical risk factors when evaluating, counseling, treating, and monitoring young children with food allergies.
Purpose: Few studies have demonstrated the effects of aeroallergen sensitization on the development of atopic dermatitis (AD) in young children. This study aimed to investigate the sensitization rate of food and aeroallergens in AD patients under 2 years of age and to compare clinical characteristics between IgE-and non-IgE-mediated AD patients. Methods: Children aged less than 2 years who had visited CHA Bundang Medical Center from 2013 through 2016 were enrolled. Allergen sensitization was measured by specific IgE levels for common allergens. Detailed information was obtained using an atopy questionnaire. Results: A total of 173 patients were examined, 118 (68.2%) were male patients. The prevalence of aeroallergen sensitization under 1 year of age was 4.8% and increased to 19.5% for children aged 2 years (P= 0.005). The mean age (13.6± 6.3 months vs. 9.0± 5.1 months, P= 0.003) and the proportion of children born prematurel (15.4% vs. 2.3%, P= 0.013) were higher in the aeroallergen-sensitized group than in nonsensitized group. Sensitization to food allergens between children aged less than 1 year and 2 years appeared to be similar (61.1% vs. 57.1%, P= 0.651). There were no significant differences in clinical characteristics between food allergen IgE-mediated and non-IgE-mediated AD children. Conclusion: Aeroallergen sensitization increased markedly in AD patients aged 2 years which is about 4 times that of the general population. However, there were no significant differences in clinical manifestations between allergen IgE-mediated and non-IgEmediated AD children in both food and aeroallergens.

PurposeChest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis.MethodsWe obtained the following data at admission: sex, age, neonatal history, past history of hospitalization for respiratory illnesses, heart rate, respiratory rate, the presence of fever, total duration of fever, oxygen saturation, laboratory parameters (i.e., complete blood cell count, high-sensitivity C-reactive protein [hs-CRP], etc.), and chest radiography.ResultsThe study comprised 279 young children. Of these, 26 had a chest radiograph revealing opacity (n=24) or atelectasis (n=2). Multivariate logistic regression analysis showed that after adjustment for confounding factors, the clinical predictors associated with pathologic chest radiographic findings in young children admitted with bronchiolitis were elevated hs-CRP level (>0.3 mg/dL) and past history of hospitalization for respiratory illnesses (all P<0.05).ConclusionThe current study suggests that chest radiographs in young children with typical clinical manifestations of bronchiolitis have limited value. Nonetheless, young children with clinical factors such as high hs-CRP levels at admission or past history of hospitalization for respiratory illnesses may be more likely to have pathologic chest radiographic findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
