Abstract
OBJECTIVE We aim to assess the risk factors of uncontrolled asthma in children and adolescents. METHODS A systemic search was conducted from electronic databases (PubMed/Medline, Cochrane Library, and Google Scholar) from inception to July 17, 2023. All statistical analyses were conducted in Review Manager 5.4.1. Studies meeting inclusion criteria were selected. A random-effects model was used when heterogeneity was seen to pool the studies, and the result was reported in the odds ratio and the corresponding 95% confidence interval. We also used a narrative approach where it was not feasible to quantitatively assess the outcome. RESULTS Ten observational studies were used to conduct this systematic review and meta-analysis. A quantitative analysis of five factors was done. Pooled analysis showed a statistically significant risk of uncontrolled asthma in association with past hypersensitivity reactions (standardized mean difference [SMD] = 1.51 (1.16, 1.98); p = .002; I2 = 84%) and incomplete controller adherence (SMD = 3.15 (1.83, 5.41); p < .0001; I2 = 94%). While non-significant relation was seen in parental asthma (SMD = 1.23 (0.98, 1.55); p = .07; I2 = 15%), oral corticosteroid use (SMD = 0.99 (0.72, 1.36); p = .96; I2 = 81%) and education of caregivers (SMD = 0.99 (0.72, 1.36); p = .96; I2 = 81%). Some other factors were also discussed qualitatively. CONCLUSION Our study shows that some significant risk factors might cause uncontrolled asthma in children and adolescents like past hypersensitivity reactions and incomplete controller adherence.

Abstract
Objective: The Child Asthma Risk Assessment Tool (CARAT) identifies risk factors for asthma morbidity. We hypothesized that CARAT-identified risk factors (using a CARAT adapted for inpatient use) would be associated with future healthcare utilization and would identify areas for intervention.Methods: We reviewed CARAT data collected during pediatric asthma admissions from 2010-2015, assessing for risk factors in environmental, medical, and social domains and providing prompts for inpatient (specialist consultation or social services engagement) and post-discharge interventions (home care visit or home environmental assessment). Confirmatory factor analysis identified groups of CARAT-identified risk factors with similar effects on healthcare utilization (latent factors). Structural equation models then evaluated relationships between latent factors and future utilization.Results: There were 2731 unique patients admitted for asthma exacerbations; 1015 (37%) had complete CARAT assessments and were included in analyses. Those with incomplete CARAT assessments were more often younger and privately-insured. CARAT-identified risk factors across domains were common in children hospitalized for exacerbations. Risks in the environmental domain were most common. Inpatient asthma consults by pulmonologists or allergists and home care referrals were the most frequent interventions indicated (62%, 628/1015, and 50%, 510/1015, respectively). Two latent factors were positively associated with healthcare utilization in the year after index stay - social stressors and known/suspected allergies (both p < 0.05). Stratified analyses analyzing data just from those children with prior healthcare utilization also indicated known/suspected allergies to be positively associated with future utilization.Conclusions: Inpatient interventions to address social stressors and allergic profiles may be warranted to reduce subsequent asthma morbidity.

Abstract
BACKGROUND Asthma is a significant cause of morbidity and mortality in the pediatric population. Atopic dermatitis (AD) is often the first step in the atopic march leading to the development of asthma, allergic rhinitis, and food allergies in the future. OBJECTIVE This study aimed to evaluate the severity differences between asthmatic children with and without atopic march in addition to characteristics of asthmatic patients with GER and ear-nose-and-throat (ENT) pathologies. METHODS A total of 616 pediatric asthmatic patients were enrolled. The study subjects were divided into two groups. Group A included asthmatic children with a history of AD. Group B had asthmatic children without a history of AD. Multiple factors were studied, including sex, race/ethnicity, family history of atopy, asthma severity, allergic rhinitis, food allergies, smoke exposure, ear-nose-and-throat (ENT) pathologies, gastroesophageal reflux (GER), frequency of systemic steroid use, and hospital admission rates. RESULTS Our results revealed that patients with atopic march are at risk of developing a higher severity of asthma, resulting in increased morbidity. In contrast, asthmatic patients without atopic march had a milder asthma severity, less need for steroids, and fewer hospital admissions. A higher prevalence of ENT pathologies and/or GER existed among asthmatic children without atopic march. CONCLUSION Our findings suggest that patients with atopic march should be expected to exhibit a more severe phenotype of asthma with increased asthma morbidity. Asthmatic patients without atopic march had a milder asthma phenotype, less need for steroids, and fewer hospital admissions. A higher prevalence of ENT pathologies and/or GER existed among asthmatic children without atopic march.

Front Immunol 2023; 14:1167562. [PMID: 37228621 PMCID: PMC10205017 DOI: 10.3389/fimmu.2023.1167562] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 04/14/2023] [Indexed: 05/27/2023] Open
Abstract
Background The prevalence of food allergy (FA) is increasing. Decreases in the diversity of gut microbiota may contribute to the pathogenesis of FA by regulating IgE production of B cells. Intermittent fasting (IF) is a popular diet with the potential to regulate glucose metabolism, boosting immune memory and optimizing gut microbiota. The potential effect of long-term IF on the prevention and treatment of FA is still unknown. Methods Two IF protocols (16 h fasting/8 h feeding and 24 h fasting/24 h feeding) were conducted on mice for 56 days, while the control mice were free to intake food (free diet group, FrD). To construct the FA model, all mice were sensitized and intragastrical challenged with ovalbumin (OVA) during the second half of IF (day 28 to day 56). Rectal temperature reduction and diarrhea were recorded to evaluate the symptoms of FA. Levels of serum IgE, IgG1, Th1/Th2 cytokines, mRNA expression of spleen T cell related transcriptional factors, and cytokines were examined. H&E, immunofluorescence, and toluidine blue staining were used to assess the structural changes of ileum villi. The composition and abundance of gut microbiota were analyzed by 16srRNA sequencing in cecum feces. Results The diarrhea score and rectal temperature reduction were lower in the two fasting groups compared to the FrD groups. Fasting was associated with lower levels of serum OVA-sIgE, OVA-sIgG1, interleukin (IL)-4 and IL-5, and mRNA expression of IL-4, IL-5, and IL-10 in the spleen. While no significant association was observed in interferon (IFN)-γ, tumor necrosis factor (TNF)-α, IL-6, IL-2 levels. Less mast cell infiltration in ileum was observed in the 16h/8h fasting group compared to the FrD group. ZO-1 expression in the ileum of the two fasting groups was higher in IF mice. The 24h/24h fasting reshaped the gut microbiota, with a higher abundance of Alistipes and Rikenellaceae strains compared to the other groups. Conclusion In an OVA-induced mice FA model, long-term IF may attenuate FA by reducing Th2 inflammation, maintaining the integrity of the intestinal epithelial barrier, and preventing gut dysbiosis.

Front Immunol 2022; 13:982660. [PMID: 36578482 PMCID: PMC9791183 DOI: 10.3389/fimmu.2022.982660] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 11/22/2022] [Indexed: 12/14/2022] Open
Abstract
Objective The prevalence of food allergy (FA) has been increasing in recent years and has become an important public health, food safety, and clinical nutrition problem. However, population-based studies on the prevalence of FA are very limited in China. This study aims to determine the prevalence and pattern of parent-reported FA among school children in Jiangxi Province, China. Methods A multicenter cross-sectional study on FA was conducted on primary school children aged 6-11 years old using random cluster sampling with a questionnaire survey. Parent-reported FA was used and defined as individual-reported FA by parent or guardian through a questionnaire in this study. Result Among the total of 8,856 (96.36%) complete questionnaires received, 727 (8.2%) children had adverse reactions to food (ARF). The prevalence rates of parent-reported FA and doctor-diagnosed FA were 6.2% and 3.3%, respectively. Animal-derived foods were the main causative source of FA, and the three leading allergenic foods were shrimp, mango, and mollusks. Skin reactions were the most common clinical manifestations of FA, accounting for 63.7%, and 45.32% of the subjects with parent-reported FA experienced severe allergic reactions. There was a significant difference in parent-reported FA between different survey centers, and FA risk increased significantly in children with other allergic diseases (P<0.001) and small family size (P=0.026). The FA prevalence was significantly higher among children aged 8-11 years than those aged 6-7 years (P=0.020). Conclusions A high prevalence of parent-reported FA was observed among children in general primary schools in Jiangxi Province, China. Shrimp, mango, and mollusks were the most common causative foods. The main common symptoms of FA were adverse reactions relating to the skin system. The rate of severe allergic reactions was also high in Jiangxi Children with reported FA. Local standards and policies for the prevention and management of FA need to be adjusted on a timely basis according to actual local conditions.

Abstract
BACKGROUND Personal genetic predisposition and early life environmental factors are important for the development of childhood asthma. We aimed to search whether egg, milk and mite sensitizations at 0-2 years old are risk factors for asthma symptoms at 9-11 years old. METHODS A total of 210 wheezer children who had specific immunoglobulin (Ig) E in 2010-2012 were included in the study (followed by pediatric allergy). Patients were divided into non-atopic (group 1, n = 157) and atopic patients [groups 2-7, n = 53 (5 patients were in both group 4 and group 5)] based on sensitizations. Using the International Study of Asthma and Allergy in Childhood questionnaire, current wheeze (CW, 2nd question), exercise wheezing (EW, 7th question), and dry cough (DC, 8th question) were surveyed. Also, parental allergies, eczema at 0-2 years, current eosinophil percentage and total IgE were recorded. RESULTS Eczema was observed as an important risk factor [CW: odds ratio (OR) = 2.83, 95% confidence interval (CI) = 1.54-5.23, P ≤ 0.001; EW: OR = 2.71, 95% CI = 1.33-5.54, P = 0.006; DC: OR = 3.03, 95% CI = 1.47-6.25, P = 0.003], whereas having no atopic sensitization at 0-2-year-old (group 1) was found as a significant protective factor for asthma at 9-11 years old (CW: OR = 0.32, 95% CI = 0.15-0.70, P = 0.004; EW: OR = 0.21, 95% CI 0.10-0.44, P ≤ 0.001; DC: OR = 0.25, 95% CI = 0.10-0.59, P = 0.002). CONCLUSION Early personal eczema is a significant risk factor for the development of asthma symptoms at 9-11 years old, whereas not having an allergic sensitization at 0-2 years old (group 1) is an important protective factor.

Abstract
Purpose:
Identifying the distribution of allergens is valuable to the effective diagnosis and treatment of allergic disease. So, our aim is to explore the sensitization of food and aeroallergens in Egyptian patients with atopic asthma.
Methods:
Cross-sectional study recruited 268 Egyptian patients with atopic asthma. Asthmatic patients were assessed by the enzyme allegro sorbent test (EAST) method for specific IgE to a panel of 19 common regional inhaled allergens and 15 food allergens.
Results and Discussion:
One hundred percent of the patients were sensitive to at least one allergen. Allergy to food allergens only was 2.9%; inhaled allergens only were 26.2% and both were70.9%. Fungi (62%) were the most frequent sensitizing aeroallergen amongst our asthmatic patients, followed by the pollen allergens (42.5%) and house dust mites (HDMs) (26%). Cows’ milk (30.5%) was the most frequent sensitizing food amongst our asthmatic patients, followed by eggs (22.4%) and fish (21.6%). Mono-sensitized patients accounted for 6.7% of all cases, while polysensitized was 93.3%. Moderate and severe asthma showed a significantly higher frequency of polysensitization compared to mild asthma.
Conclusion:
Fungi and cow's milk are the chief sensitizing allergens in Egyptian patients with atopic asthma. This study represents the first report of sensitization in atopic adult asthma using a large extract panel in Upper Egypt.

Abstract
The prevalence of food allergy has increased in recent years, especially in children. Allergen avoidance, and drugs in case of an allergic reaction, remains the standard of care in food allergy. Nevertheless, increasing attention has been given to the possibility to treat food allergy, through immunotherapy, particularly oral immunotherapy (OIT). Several OIT protocols and clinical trials have been published. Most of them focus on children allergic to milk, egg, or peanut, although recent studies developed protocols for other foods, such as wheat and different nuts. OIT efficacy in randomized controlled trials is usually evaluated as the possibility for patients to achieve desensitization through the consumption of an increasing amount of a food allergen, while the issue of a possible long-term sustained unresponsiveness has not been completely addressed. Here, we evaluated current pediatric OIT knowledge, focusing on the results of clinical trials and current guidelines. Specifically, we wanted to highlight what is known in terms of OIT efficacy and effectiveness, safety, and impact on quality of life. For each aspect, we reported the pros and the cons, inferable from published literature. In conclusion, even though many protocols, reviews and meta-analysis have been published on this topic, pediatric OIT remains a controversial therapy and no definitive generalized conclusion may be drawn so far. It should be an option provided by specialized teams, when both patients and their families are prone to adhere to the proposed protocol. Efficacy, long-term effectiveness, possible role of adjuvant therapies, risk of severe reactions including anaphylaxis or eosinophilic esophagitis, and impact on the quality of life of both children and caregivers are all aspects that should be discussed before starting OIT. Future studies are needed to provide firm clinical and scientific evidence, which should also consider patient reported outcomes.

Abstract
The concept of atopy was initially developed in the first quarter of the 20th century on the basis of clinical observations without any knowledge of pathogenic mechanisms. Atopy involves a collection of comorbidities that share pathogenic features, and atopic comorbidities affect outcomes of concomitant conditions rather than existing synchronously. The clinical importance of understanding the relationship of these conditions is necessary because the treatment of one condition influences the others, and the development of one leads to or precedes the development of another. Environmental influences and multigenetic predispositions result in complex relationships among the atopic conditions sharing a type 2 pathogenesis. The specialty of Allergy and Immunology is devoted to managing the comorbidities of atopy, and better understanding of their connections can improve patient care.

Background Sensitization to peanuts and hazelnuts is common among young asthmatics and can be primary or a result of cross-reactivity. Sensitization as a result of cross-reactivity to birch pollen is typically associated to tolerance or mild and local symptoms upon intake of peanut or hazelnut. Aim The aim of this study was to investigate relationships between IgE antibody responses against peanut and hazelnut components, airway and systemic inflammation markers, lung function parameters and reported food hypersensitivity in a cohort of asthmatic children and young adults. Methods A population of 408 asthmatic individuals aged 10-35 years were investigated. Information on hypersensitivity symptoms upon intake of peanut or hazelnut were recorded in a standardized questionnaire. Fraction of exhaled nitric oxide (FeNO), blood eosinophil count (B-Eos), spirometry, methacholine challenge outcome and IgE antibodies to peanut and hazelnut allergens were measured by standard clinical and laboratory methods. Results Subjects sensitized to any of the peanut (Ara h 1, 2 or 3) or hazelnut (Cor a 9 or 14) storage proteins were significantly younger (17.6 vs 21.2 years), had higher levels of FeNO (23.2 vs 16.7 ppb) and B-Eos (340 vs 170 cells/mcl) than those displaying only pollen-related cross-reactive sensitization. Levels of FeNO correlated with levels of IgE to storage proteins in children, but not in adults. Levels of B-Eos correlated with levels of IgE to all allergen components investigated in children, but only to levels of IgE to storage proteins in adults. Anaphylaxis and skin reactions upon intake of peanuts or hazelnuts were more often reported among subjects sensitized to the respective storage proteins than among those with only pollen-related cross-reactive sensitization. As compared to peanut, hazelnut was more often reported to cause gastrointestinal symptoms and less often oral cavity symptoms. Conclusions Sensitization to peanut and hazelnut storage proteins was associated with higher levels of inflammation markers and food hypersensitivity symptoms in this population of subjects with asthma.

Prevalence and Predictors of Uncontrolled Asthma in Children Referred for Asthma and Other Atopic Diseases. J Asthma Allergy 2020; 13:67-75. [PMID: 32099412 PMCID: PMC6999583 DOI: 10.2147/jaa.s231907] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Accepted: 12/13/2019] [Indexed: 11/23/2022] Open
Abstract
Background Uncontrolled asthma in children is still highly prevalent despite the availability of effective asthma treatment. We investigated 1) the prevalence of uncontrolled asthma among children referred for asthma and referred for atopic diseases other than asthma (ie food allergy, allergic rhinitis or atopic dermatitis) to secondary care; and 2) the predictors associated with uncontrolled asthma. Methods All children (4 to 18 years) referred for asthma or atopic diseases other than asthma to 8 secondary care centers in The Netherlands were invited to an electronic portal (EP). The EP is a web-based application with several validated questionnaires including the ISAAC questionnaires and the Asthma Control Test (ACT). Children were eligible for inclusion in this study when their parents reported in the EP that their child had asthma diagnosed by a physician. The ACT was used to assess asthma control. Multiple predictors of asthma control (patient, asthma and atopic characteristics) were evaluated by univariable and multivariable logistic regression analyses. Results We included 408 children: 259 children (63%) with asthma referred for asthma and 149 children (37%) with asthma referred for atopic diseases other than asthma. Thirty-nine percent of all children had uncontrolled asthma: 47% of the children referred for asthma and 26% of the children referred for atopic diseases other than asthma. Predictors associated with uncontrolled asthma were a family history of asthma (odds ratio [OR] 2.08; 95% confidence interval [95% CI] 1.34 to 3.24), and recurrent upper and lower respiratory tract infections in the past year (OR 2.40; 95% CI 1.52 to 3.81 and OR 2.00; 95% CI 1.25 to 3.23, respectively). Conclusion Uncontrolled asthma is highly prevalent in children with asthma referred to secondary care, even if children are primarily referred for atopic diseases other than asthma. Thus, attention should be paid to asthma control in this population.

FCER2 T2206C variant associated with FENO levels in asthmatic children using inhaled corticosteroids: The PACMAN study. Clin Exp Allergy 2019; 49:1429-1436. [PMID: 31309641 PMCID: PMC6899548 DOI: 10.1111/cea.13460] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Revised: 07/05/2019] [Accepted: 07/05/2019] [Indexed: 11/27/2022]
Abstract
BACKGROUND The FCER2 gene, via encoding of the CD23 receptor, plays an important role in the regulation of IgE responses. A genetic variant of the FCER2 gene (T2206C) was previously shown to be associated with IgE levels in asthmatic children. IgE sensitization has also been linked to increased levels of fractional exhaled nitric oxide (FENO). OBJECTIVE To investigate whether the FCER2 T2206C variant influences FENO levels in asthmatic children with a reported use of inhaled corticosteroids (ICS). METHODS This cross-sectional study involved 593 asthmatic children with a reported use of ICS, availability of FENO measurements and genotyping data on the FCER2 T2206C variant (rs28364072). An additive genetic model was assumed, and the association between the FCER2 T2206C variant and the log-transformed (ln) FENO levels was evaluated using linear regression analysis, adjusted for age, sex, adapted British Thoracic Society (BTS) treatment steps and atopy. RESULTS The mean age of the population was 9.1 ± 2.2 years, and the median of FENO levels was 13.0 ppb with an interquartile range (IQR) of (8.0-27.5 ppb). The minor allele (G) frequency of rs28364072 was 29.6%, and each extra copy of the G allele was significantly associated with a lower level of the geometric mean of FENO (log scale, β = -0.12, 95% CI: -0.23, -0.02). CONCLUSION AND CLINICAL RELEVANCE Our results showed that the FCER2 T2206C variant was significantly associated with lower FENO levels in carriers of the G allele. Nevertheless, this SNP contributed little to the variability in FENO levels in this patient population. Our findings contribute to the present knowledge on FENO in asthmatic children; however, future replication studies are required to establish the role of this gene in relation to FENO.

Abstract
Over the past few decades, an increase in the prevalence of asthma and food allergy has been observed in the pediatric population. In infants, food sensitization, particularly to egg, has increased the risk of developing allergic asthma. This is even more likely if sensitization to food allergens occurs early within the first few years of life. It is indeed known that both diseases may be present simultaneously in the pediatric population, but coexistence may negatively influence the severity of both conditions by increasing the risk of life-threatening asthmatic episodes as well as food-related anaphylaxis. Therefore, an accurate clinical and phenotype characterization of this high-risk group of children with both asthma and food allergy and a more aggressive management might lead to reducing related morbidity and mortality. The aim of this review is to provide an updated overview on the close link between food allergy and asthma and their negative mutual influence.

Abstract
Asthma is a common disease in childhood with a minority of affected children having severe therapy-resistant asthma (STRA). Children with STRA can be differentiated from those with mild-moderate disease by greater allergic sensitization, increased eosinophilic airway inflammation, increased airway remodelling and reduced corticosteroid responsiveness. The aetiology of STRA in children is multifactorial but allergy seems to play a key role. Many children with asthma have coexisting allergic disease, and severe rhinitis seems to be an important driver of STRA in children. Allergies to foods, moulds, pollen and pets have also been associated with severe asthma exacerbations. Identifying allergens that are driving asthma symptoms in children with STRA may provide additional strategies for improving their disease control. Avoidance strategies may be possible. Additional monoclonal antibody therapy with Omalizumab or Mepolizumab may be helpful in children with clinically important polysensitization.

Abstract
OBJECTIVES Food allergy is an increasing burden worldwide and is a common problem within paediatric populations, affecting 5%-8% of children. Anaphylaxis caused by food proteins is a potentially life-threatening condition and all healthcare practitioners should be aware of its recognition and management. Russia is the largest country in Europe but it is still unknown whether physicians are prepared to diagnose and manage food-induced anaphylaxis effectively. We aimed to examine physicians' knowledge of diagnosis and management of food-induced anaphylaxis. SETTING, POPULATION AND OUTCOMES A survey was designed and published online at VrachiRF.ru website (for registered Russian-speaking practicing physicians). We obtained information on respondents' clinical settings, experience and specialty. Survey questions were based on a characteristic clinical scenario of anaphylaxis due to food ingestion. Outcome measures consisted of correct answers to the anaphylaxis diagnosis and management questions. RESULTS From a total of 707 of physicians accessed in the survey, 315 (45%) responded to the clinical scenario. 16 respondents reported training in allergy-immunology and have been excluded from the analysis, leaving the final sample size of 299. Respondents were paediatricians (68%) and other specialties adult physicians (32%). Overall, 100 (33%) of respondents diagnosed anaphylaxis, but only 29% of those making the correct diagnosis administered adrenalin (1:1000) intramuscular. Respondents working in secondary/tertiary clinics diagnosed anaphylaxis significantly more often (p=0.04) when compared with primary care/private practice physicians. This difference was also apparent as the most important influence on responses in the multivariate analysis. CONCLUSIONS In this national sample of Russian physicians, we found poor knowledge in both anaphylaxis diagnosis and management. Our data show that the chance of being properly diagnosed with anaphylaxis is 33% and being appropriately treated with adrenalin is 10%. These findings highlight lack of anaphylaxis knowledge among Russian physicians, both paediatricians and other specialists and illustrates the urgent need for allergy/anaphylaxis training.

Abstract
The association between atopic diseases is well known, and previous research has shown that having one atopic disease can predispose to having another. The link between asthma and food allergy has been well researched, but the exact relationship between the two atopic conditions is not fully understood. Food allergic infants are at increased risk for the development of asthma and are at risk of food-induced asthmatic episodes and also anaphylaxis. Having a diagnosis of both food allergy and asthma has also been shown to have an effect on the severity of a patient's disease including being at greater risk of severe asthmatic episodes. Therefore, understanding the relationship between these two conditions in order to treat and manage these children safely is crucial to clinicians.

Abstract
OBJECTIVES We investigated patterns of multimorbidities among asthma, allergies, and respiratory illnesses in preschool children. We investigated multimorbidities of lifetime asthma, allergic rhinitis, eczema, food allergy, pneumonia, and ear infections; and multimorbidities of current (in the last year before the survey) wheeze, dry cough, rhinitis, eczema, and common cold during childhood. We further analyzed whether prevalences of these multimorbidities were due to chance. METHODS A cross-sectional study was conducted in 72 kindergartens of Shanghai, China. Parents of preschool children were surveyed with a modified ISAAC questionnaire. Observed prevalences (OPs), expected prevalences (EPs), absolute excess comorbidities (AECs), and relative excess comorbidities (RECs) of various combinations of illnesses were calculated to indicate whether the combined illnesses were related. RESULTS We analyzed questionnaires for children aged 4-6 years, whose 13,335 questionnaires were the majority of the total 15,266 returned questionnaires (response rate: 85.3%). The studied illnesses were common. For children who had more than three lifetime or current illnesses, OPs tended to be higher than EPs. Most OPs and EPs were higher in boys than in girls, and were higher in children with a family history of atopy (FHA) than in children without FHA. AECs and RECs between boys and girls as well as between children with and without FHA were substantially different. CONCLUSIONS Our findings suggest that multimorbidities among childhood asthma, allergies, and respiratory illnesses are likely not random, but rather share etiology. Specific patterns of childhood asthma multimorbidities perhaps differ between boys and girls and between children with and without FHA.

Abstract
BACKGROUND AND OBJECTIVE Despite the growing evidence of a possible link between asthma and food allergy (FA), so far, the involvement of food in inducing respiratory symptoms has not been fully evaluated. The objective of this study was to evaluate the impact of food allergens on respiratory symptoms and bronchial reactivity (BHR) in schoolchildren with asthma. METHODS The initial study group consisted of 362 children with asthma. In the end, 22 children with concomitant FA, and 18 without FA, were selected to participate in the study. Spirometry and Methacholine Inhalation Challenge (MIC) were conducted prior to and after the completion of a double blind placebo control food challenge (DBPCFC). RESULTS The food-induced asthmatic reactions were observed in nine (2.5%) out of all 362 children with asthma. Mean FEV1 prior to and after allergen or placebo challenge did not differ between the groups studied. Increase of BHR after DBPCFC was seen in 17 (4.7%) children with asthma. The mean PC20 value in children with FA was 1.41 ± 1.12 mg/ml prior to the allergen challenge and 0.86 ± 0.71 mg/ml (P = 0.002) after the test, whereas these values were 1.93 ± 1.68 mg/ml and 2.02 ± 1.75 mg/ml, respectively, in children without FA (P > 0.05). Significant differences were noted after the allergen provocation in children with FA as compared to children without FA (P = 0.007). CONCLUSIONS Although food allergens are a rare trigger of food-induced asthmatic reactions in schoolchildren with asthma, they could enhance BHR, despite a lack of evident clinical respiratory signs and decreased in FEV1 values after food challenge.

Abstract
BACKGROUND Risk factors of pediatric inflammatory bowel disease (PIBD) are incompletely understood. Recently, we reported that among patients with PIBD, a previous diagnosis of cow's milk allergy (CMA) and asthma occurred more frequently than among age- and sex-matched peers. We tested at a national level the hypothesis that CMA is associated with the risk of contracting PIBD. METHODS A nationwide birth cohort (n = 225,041), including all Finnish children born between 1999 and 2002, was followed up until July 1, 2014. We identified all children with a diagnosis of CMA, asthma, and PIBD from a national register; the data were based on certificates, including diagnostic criteria. The 95% confidence intervals (CI) for the incidence rates per 100,000 person-years were calculated assuming a Poisson distribution. RESULTS We identified 7,910 infants with CMA yielding a cumulative incidence of 3.5% by 2 years of age. The cumulative incidence of PIBD was 0.14% (n = 316) and that of asthma 6.6% (14,807). Children with CMA were more likely to develop PIBD than non-CMA children, incidence ratio 2.6 (95% CI 1.7-3.8). Children with a diagnosis of CMA contracted PIBD at a younger age than the respective non-CMA group (9 vs. 11 years, p < 0.05). The risk was more evident for ulcerative colitis than for Crohn's disease. The association between CMA and asthma was stronger than that between CMA and PIBD. CONCLUSIONS CMA in infancy is associated with subsequent development of asthma and PIBD. This suggests that in a subgroup of patients, CMA may share underlying background with PIBD, warranting thorough follow-up.

Abstract
Food allergy and respiratory allergy are two frequently associated diseases and with an increasing prevalence. Several reports show the presence of respiratory symptoms in patients with food allergy, while certain foods may be related to the development or exacerbation of allergic rhinitis and asthma. The present update focuses on this relationship, revealing a pathogenic and clinical association between food and respiratory allergy. This association is even more intense when the food hypersensitivity is persistent or starts in the early years of life. Food allergy usually precedes respiratory allergy and may be a risk factor for allergic rhinitis and asthma, becoming a relevant clinical marker for severe atopic asthma. Furthermore, the presence of co-existing asthma may enhance life-threatening symptoms occurring during a food allergic reaction. Recommendations for dietary restrictions during pregnancy and breastfeeding to prevent the development of respiratory allergy are controversial and not supported by consistent scientific data. Current recommendations from medical societies propose exclusive breastfeeding during the first four months of life, with the introduction of solid food in the fourth to the seventh month period of life. A delayed introduction of solid food after this period may increase the risk of developing subsequent allergic conditions. Further studies are encouraged to avoid unjustified recommendations involving useless dietary restrictions.

Abstract
OBJECTIVES Children with asthma and allergies--particularly food and/or multiple allergies-are at risk for adverse asthma outcomes. This analysis describes allergy prevalence trends among US children by asthma status. METHODS We analyzed 2001-2013 National Health Interview Survey data for children aged 0-17 years. We estimated trends for reported respiratory, food, and skin allergy and the percentage of children with one, two, or all three allergy types by asthma status. We estimated unadjusted trends, and among children with asthma, adjusted associations between demographic characteristics and allergy. RESULTS Prevalence of any allergy increased by 0.3 percentage points annually among children without asthma but not among children with asthma. However, underlying patterns changed among children with asthma: food and skin allergy prevalence increased as did the percentage with all three allergy types. Among children with asthma, risk was higher among younger and non-Hispanic black children for reported skin allergy, among non-Hispanic white children for reported respiratory allergy, and among non-poor children for food and respiratory allergies. Prevalence of having one allergy type decreased by 0.50 percentage points annually, while the percent with all three types increased 0.2 percentage points annually. Non-poor and non-Hispanic white children with asthma were more likely to have multiple allergy types. CONCLUSIONS While overall allergy prevalence among children with asthma remained stable, patterns in reported allergy type and number suggested a greater proportion may be at risk of adverse asthma outcomes associated with allergy: food allergy increased as did the percentage with all three allergy types.

Abstract
Background Very few studies have explored the distinguishing features of severe asthma in childhood in Europe, and only one study was conducted in Southern Europe. The aim of this study was to provide a detailed characterization of children with severe asthma treated in specialized pediatric asthma centers across Italy. Methods We conducted a web-based data collection of family, environmental, clinical and laboratory characteristics of 41 patients aged 6–17 years with severe asthma, defined according to the recent guidelines of the European Respiratory Society and the American Thoracic Society, and 78 age-matched peers with non-severe persistent asthma. The patients have been enrolled from 16 hospital-based pediatric pulmonology and allergy centers in Northern, Central, and Southern Italy. Logistic regression analysis assessed the relationship between patients’ characteristics and severe asthma or non-severe persistent asthma. Results Features independently and significantly associated with severe asthma included lifetime sensitization to food allergens [Odds ratio (OR), 4.73; 95 % Confidence Interval (CI), 1.21–18.53; p = 0.03], lifetime hospitalization for asthma (OR, 3.71; 95 % CI, 1.11–12.33; p = 0.03), emergency-department visits for asthma during the past year (OR = 11.98; 95 % CI, 2.70–53.11; p = 0.001), and symptoms triggered by physical activity (OR = 12.78; 95 % CI, 2.66–61.40; p = 0.001). Quality-of-life score was worse in patients with severe asthma than in subjects with non-severe persistent asthma (5.9 versus 6.6, p = 0.005). Self-perception of wellbeing was compromised in more than 40 % of patients in both groups. Children with severe asthma had lower spirometric z scores than non-severe asthmatic peers (all p < 0.001), although 56 % of them had a normal forced expiratory volume in 1 s. No differences were found between the two groups for parental education, home environment, patients’ comorbidities, adherence to therapy, exhaled nitric oxide values, and serum eosinophils and IgE . Conclusions As expected, children with severe asthma had more severe clinical course and worse lung function than peers with non-severe persistent asthma. Unlike previous reports, we found greater sensitization to food allergens and similar environmental and personal characteristics in patients with severe asthma compared to those with non-severe persistent asthma. Psychological aspects are compromised in a large number of cases and deserve further investigation.

Abstract
Epidemiological data suggest a link between food allergies and the subsequent development of asthma. Although this progression may result from the additional effects of exposure to multiple allergens, whether both allergies amplify each other's effects remains unknown. This study investigated whether oral exposure to food allergens influences the outcomes of subsequent respiratory exposure to an asthma-inducing allergen. Mice were sensitized and orally challenged with wheat (FA) and then exposed to house dust mite (HDM) extract (RA). Immunoglobulin (Ig), histamine, and cytokine levels were assayed by ELISA. Intestinal and lung physiology was assessed. Ig levels, histamine release, and cytokine secretion were higher after exposure to both allergens than after separate exposure to each. Intestinal permeability was higher, although airway hyper-responsiveness and lung inflammation remained unchanged. Exposure to food and respiratory allergens amplifies systemic and gut allergy-related immune responses without any additional effect on lung function and inflammation.

Abstract
Purpose Recent studies indirectly suggest a possible link between food allergy (FA) and asthma. Most of them have evaluated the occurrence of FA in asthmatic children, especially in the first year of life, using questionnaire-based studies or specific IgE (sIgE) assay. The aim of this study was to evaluate the prevalence and clinical impact of IgE-mediated FA in school children with asthma using a double-blind placebo-controlled food challenge (DBPCFC). Methods The study group consisted of school children with atopic asthma who were admitted to the Department of Pediatric Allergology, Gastroenterology and Nutrition, Medical University of Lodz, for the evaluation of food hypersensitivity. The diagnosis of FA was established using questionnaires, sIgE analysis, and the DBPCFC. Asthma severity and asthma control state were also assessed. Results A relationship between consumed food and complaints was reported in 180 children (49.7%). Seventy children (19.3%) were sensitized to food allergens. IgE-mediated FA was confirmed in 24 children (6.6%), while 11 children (3%) demonstrated respiratory symptoms. Food-induced asthma exacerbations were observed in 9 patients (2.5%). Statistically significant differences in the prevalence of atopic dermatitis (P<0.002), urticaria (P<0.03), digestive symptoms (P<0.03), rhinitis (P<0.02), sIgE level (P<0.001), positive family history of atopy (P<0.001) and FA in history (P<0.001) were found between asthmatic children with FA and those without. Children with food-induced asthma exacerbations demonstrated significantly greater severity, poorer controls, and worse morbidity compared to those without. Conclusions Although food-induced respiratory reactions in children with asthma were rare, they were classified as severe and associated with worse morbidity, greater severity, and poorer control. As the most commonly observed symptoms were coughing and rhinitis, which can be easily misdiagnosed, a proper diagnosis is essential for improving the management of both clinical conditions.

Abstract
Background The relationship between perceived food hypersensitivity in asthmatics, food allergen sensitization, asthma control and asthma-related quality of life has not been studied. Objective Our aim was to study the prevalence of perceived food hypersensitivity in a cohort of young asthmatics, its relation to food allergen sensitization, and any correlation to asthma control and asthma-related quality of life. Methods Perceived food hypersensitivity, as well as IgE sensitization to common food allergens, levels of exhaled nitric oxide (FeNO), and blood eosinophil counts (B-Eos) were assessed in 408 subjects (211 women) with asthma, aged (mean ± SEM) 20.4 ± 0.3 years. Subjects filled out the Asthma Control Test (ACT) and the Mini Asthma Quality of Life Questionnaire (Mini-AQLQ). Inflammation was assessed by means of FeNO and B-Eos. Results Fifty-three per cent of subjects reported food hypersensitivity. A corresponding food allergen sensitization was found in 68% of these subjects. Non-atopic subjects with perceived food hypersensitivity (n = 31) had lower ACT (19 (15 - 22) vs. 21 (20 - 23), p < 0.001) and Mini-AQLQ -scores (5.3 (4.3 - 6.1) vs. 6.1 (5.5 - 6.5), p < 0.001) than subjects with no food hypersensitivity (n = 190), despite lower levels of FeNO and B-Eos (p < 0.05). Conclusions and Clinical Relevance Food hypersensitivity was commonly reported among young asthmatics. In a majority of cases, a corresponding food allergen sensitization was found. A novel and clinically important finding was that non-atopic subjects with perceived food hypersensitivity were characterized by poorer asthma control and asthma-related quality of life.

Abstract
BACKGROUND Food allergy has been gaining increasing attention, mostly as causing gastrointestinal and cutaneous reactions. Its role in asthma seems to be under-recognised. OBJECTIVES This study's aim is to explore the frequency of involvement of a common food, namely cow's milk, in childhood asthma. METHODS 32 children (5 months to 11 years; median 24 months; mean 34 months) with asthma and a suspected history of cow's milk allergy were studied. They underwent skin prick testing (SPT) and specific IgE (sIgE) testing to whole cow's milk (WCM), casein, α-lactalbumin, and β-lactoglobulin, followed by single-blind oral milk challenge. RESULTS Reactions to milk challenge occurred in 12 (37.5%) including wheezing in 5 (41.7%, or 15.6% of the whole group). Children who developed wheezing at the time of challenge were younger than those who had negative challenge (23.0 months vs. 34.8 months). Challenge was positive in 33.3% of subjects who had a positive SPT, and SPT was positive in 50% of challenge-positive subjects. Regarding sIgE, challenge was positive in 26.7% of sIgE-positive subjects, and sIgE was positive in 33.3% of challenge positive subjects. Skin or serum testing with individual protein fractions did not seem to add significant advantage over testing with WCM alone. CONCLUSION This study shows that cow's milk can cause wheezing in children with asthma. Although SPT seemed to be more reliable than sIgE testing, both had suboptimal reliability. It is worth considering possible milk allergy in children with asthma, particularly when poorly controlled in spite of proper routine management.

Abstract
Food allergy is a growing public health concern in the United States that affects an estimated 8% of children. Food allergy is defined as an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a specific food. Nearly 40% of children with food allergy have a history of severe reactions that if not treated immediately with proper medication can lead to hospitalization or even death. The National Institute of Allergy and Infectious Diseases (NIAID) convened an expert panel in 2010 to develop guidelines outlining evidence-based practices in diagnosing and managing food allergy. The purpose of this review is to aid clinicians in translating the NIAID guidelines into primary care practice and includes the following content domains: (1) the definition and mechanism of childhood food allergy, (2) differences between food allergy and food intolerance, (3) the epidemiology of childhood food allergy in the United States, (4) best practices derived from the NIAID guidelines focused on primary care clinicians' management of childhood food allergy, (5) emerging food allergy treatments, and (6) future directions in food allergy research and practice. Articles focused on childhood food allergy were considered for inclusion in this review. Studies were restricted to the English language and to those published within the past 40 years. A cross-listed combination of the following words, phrases, and MeSH terms was searched in PubMed and Google Scholar to identify relevant articles: food allergy, food hypersensitivity, child, pediatric, prevalence, and epidemiology. Additional sources were identified through the bibliographies of the retrieved articles.

Abstract
BACKGROUND Asthma is the most common chronic respiratory disease in childhood. The clinical presentation of asthma may worsen after food allergen ingestion in sensitized patients. To avoid nonspecific dietary restrictions in children with asthma, laboratory-based advice about foods is potentially helpful. The purpose of this study was to determine food sensitization in children with asthma. METHODS Seventy-nine children with mild to moderate persistent asthma were included in this study. Commercial food allergens including cow's milk, egg white, almond, potato, and soybean were used in skin prick tests. Specific IgE to 20 common food allergens was also measured in serum. RESULTS Twelve (15.2%) of the patients had a positive skin prick test to at least one of the five food extracts. Sensitization was detected by skin prick tests to cow's milk and egg white (each 6.3%), almond (3.8%), potato (2.5%) and soybean (1.3%). Specific IgE levels ≥0.35 kAU/L were detected in the serum of 47% of the children with asthma. The most common food allergens were cow's milk (26.6%), hazelnuts (25.3%), wheat flour (15.2%) and egg white (12.6%). Patients with a history of at least one hospital admission due to asthma attack had a higher rate of sensitization to egg. CONCLUSIONS In our study, food sensitization was frequent in Iranian children with asthma. Although clinical food allergy could not be evaluated because food challenge tests were not used in our study, skin prick tests and serum-specific IgE to common food allergens might be helpful in identifying children with food sensitization.

Abstract
The increased consumption of fish and shellfish has resulted in more frequent reports of adverse reactions to seafood, emphasizing the need for more specific diagnosis and treatment of this condition and exploring reasons for the persistence of this allergy. This review discusses interesting and new findings in the area of fish and shellfish allergy. New allergens and important potential cross-reacting allergens have been identified within the fish family and between shellfish, arachnids, and insects. The diagnostic approach may require prick to-prick tests using crude extracts of both raw and cooked forms of seafood for screening seafood sensitization before a food challenge or where food challenge is not feasible. Allergen-specific immunotherapy can be important; mutated less allergenic seafood proteins have been developed for this purpose. The persistence of allergy because of seafood proteins' resistance after rigorous treatment like cooking and extreme pH is well documented. Additionally, IgE antibodies from individuals with persistent allergy may be directed against different epitopes than those in patients with transient allergy. For a topic as important as this one, new areas of technological developments will likely have a significant impact, to provide more accurate methods of diagnosing useful information to patients about the likely course of their seafood allergy over the course of their childhood and beyond.

Abstract
BACKGROUND Asthma is associated with food allergies in a significant number of children, with evidence linking allergies to asthma severity and morbidity. In this study, we tested our hypothesis that the eosinophilic lower airway inflammation is higher in asthmatic children with food allergies. AIMS The aims of the study were to compare the eosinophilic inflammatory markers in asthmatic children with and without food allergies. MATERIALS AND METHODS Children with asthma, with (n = 22) and (n = 53) without food allergies were included. All subjects were classified according to the GINA guidelines (2009) and had received at least 3 months of anti-inflammatory therapy prior to testing. Fractional exhaled nitric oxide and sputum differential counts were performed using standard techniques. RESULTS Children with asthma and food allergies had significantly higher fractional exhaled nitric oxide median (range) [(22.4 (6.1-86.9) vs. 10.3 (2.7-38.7) (p = 0.01)] and sputum eosinophil percentage [15.5 (5.0-53.0) vs. 2.0 (0-20) (p < 0.001)] compared with asthmatic children without allergies. CONCLUSION These results suggest that the children with asthma and food allergies have increased eosinophilic inflammation of the airways.

Abstract
PURPOSE OF REVIEW To consider the possible links between food allergy and asthma. RECENT FINDINGS Food allergy and asthma coexist in many children, and recent studies demonstrate that having these comorbid conditions increases the risk for morbidity. Children with food allergies and asthma are more likely to have near-fatal or fatal allergic reactions to food and more likely to have severe asthma. SUMMARY Although a causal link has not been determined, increased awareness of the heightened risks of having both of these common childhood conditions and good patient/parent education and management of both conditions can lead to improved outcomes.

Abstract
BACKGROUND Studies have demonstrated that IgE-binding cross-reactive epitopes between shrimp, cockroach, and house dust mite tropomyosins can account for the presence of detectable IgE to shrimp in patients with cockroach and dust mite allergies. OBJECTIVE We investigated the correlation between IgE-mediated sensitization to shrimp, cockroach, and dust mite in relation to allergen exposure in inner-city children. METHODS Five hundred four serum samples from the National Cooperative Inner-City Asthma Study were evaluated for specific IgE to shrimp, and the results were compared with specific IgE to cockroach (Blattella germanica) and dust mite (Dermatophagoides farinae). Associations between IgE sensitization to these allergens and environmental exposures were determined. RESULTS There was a strong positive correlation between shrimp, cockroach, and dust mite IgE levels. High exposure to cockroach (B germanica) in the home, particularly in the bedroom and television room, was significantly correlated with higher shrimp and cockroach IgE levels. In contrast, high exposure to dust mite in the home was highly correlated with IgE levels to D farinae but not with shrimp IgE levels. There is a synergistic relationship between cockroach IgE levels and exposure in predicting shrimp IgE levels. CONCLUSIONS For children with evidence of IgE-mediated sensitization to cockroach and shrimp, having high exposure to cockroach in the home can contribute to higher shrimp IgE levels, which might not correlate with clinical reactivity. Further patient evaluations with clinical histories of shrimp exposure and reactions, as well as oral food challenges, would have to be performed to confirm these findings.

Abstract
BACKGROUND In Canada, the pH1N1 influenza vaccine is recommended for children, particularly those less than 5 years of age or with chronic underlying disease. The pH1N1 vaccine, which contains residual allergenic egg white proteins, may pose a risk for vaccination of egg-allergic children. OBJECTIVE To describe the outcome of pH1N1 influenza vaccine administration to egg-allergic children at risk for severe H1N1 disease. DESIGN/METHOD Prospective observational cohort study. Children identified as at high risk for egg allergy and H1N1 influenza were vaccinated using a two-dose split protocol in a controlled medical setting. Children were given an initial test dose; if no reaction was noted, the remainder of the dose was administered and the children were followed for allergic reactions. Those who tolerated the split dose and required a second dose of vaccine were offered vaccination four weeks later as one injection. RESULTS Sixty-two egg-allergic children considered at high risk for H1N1 disease received the adjuvanted pH1N1 vaccine. Egg allergy was diagnosed both clinically by an allergist and using skin and/or serum IgE testing. Within one hour of immunization, 2 children developed hives, 1 had a vasovagal response and 1 had a hypo-responsive episode. Fourteen children received the second H1N1 dose and 1 developed erythema and itching. There were no anaphylactic reactions. CONCLUSION Administration of the adjuvanted pH1N1 vaccine in egg-allergic children at risk for severe H1N1 influenza was safe when performed in a two-dose split protocol in a controlled medical setting.

Abstract
Asthma in children with sickle cell anemia (SCA) is associated with increased morbidity and mortality. However, the definition of asthma in SCA is based on a physician's impression. In a retrospective cohort of children with SCA, relationships between a physician diagnosis of asthma and total and allergen-specific immunoglobulin E levels were evaluated. In children with SCA, elevated total and specific immunoglobulin E levels were significantly associated with a diagnosis of asthma (P<0.05), further supporting the concept that asthma is a separate comorbid condition of SCA.

Abstract
Food allergy is an important public health problem that affects children and adults and may be increasing in prevalence. Despite the risk of severe allergic reactions and even death, there is no current treatment for food allergy: the disease can only be managed by allergen avoidance or treatment of symptoms. The diagnosis and management of food allergy also may vary from one clinical practice setting to another. Finally, because patients frequently confuse nonallergic food reactions, such as food intolerance, with food allergies, there is an unfounded belief among the public that food allergy prevalence is higher than it truly is. In response to these concerns, the National Institute of Allergy and Infectious Diseases, working with 34 professional organizations, federal agencies, and patient advocacy groups, led the development of clinical guidelines for the diagnosis and management of food allergy. These Guidelines are intended for use by a wide variety of health care professionals, including family practice physicians, clinical specialists, and nurse practitioners. The Guidelines include a consensus definition for food allergy, discuss comorbid conditions often associated with food allergy, and focus on both IgE-mediated and non-IgE-mediated reactions to food. Topics addressed include the epidemiology, natural history, diagnosis, and management of food allergy, as well as the management of severe symptoms and anaphylaxis. These Guidelines provide 43 concise clinical recommendations and additional guidance on points of current controversy in patient management. They also identify gaps in the current scientific knowledge to be addressed through future research.

Abstract
BACKGROUND Children with food allergies often have concurrent asthma. OBJECTIVE The authors aimed to determine the prevalence of asthma in children with food allergies and the association of specific food allergies with asthma. METHODS Parental questionnaire data regarding food allergy, corroborated by allergic sensitization were completed for a cohort of 799 children with food allergies. Multivariate regression analysis tested the association between food allergy and reported asthma. RESULTS In this cohort, the prevalence of asthma was 45.6%. After adjusting for each food allergy, environmental allergies, and family history of asthma, children with egg allergy (odds ratio [OR] = 2.0; 95% confidence interval [CI] = 1.3-3.2; P < .01) or tree nut allergy (OR = 2.0; 95% CI = 1.1-3.6; P = .02) had significantly greater odds of report of asthma. CONCLUSION There is a high prevalence of asthma in the food-allergic pediatric population. Egg and tree nut allergy are significantly associated with asthma, independent of other risk factors.

Abstract
BACKGROUND Cow's milk allergy (CMA) has been found to be associated with an increased incidence of asthma at school age. However, prospective population-based studies of CMA and the development of airway inflammation and bronchial hyperresponsivess (BHR) are lacking. OBJECTIVE The aims of this study was to evaluate CMA as a risk factor for BHR and airway inflammation presented later in childhood. METHODS We followed prospectively 118 children with CMA and invited them to a clinical visit at a mean age of 8.6 years including the measurement of exhaled nitric oxide (FE(NO) ) and bronchial challenge with histamine. Ninety-four patients and 80 control subjects from the same cohort participated. RESULTS At school age, children with a history of CMA had higher FE(NO) levels (P=0.0009) and more pronounced responsiveness to histamine (P=0.027) than their controls. Stratified analysis showed a significant difference only in IgE-positive CMA. Multinomial logistic regression analysis showed that IgE-positive CMA [odds ratio (OR) 3.51; 95% confidence intervals (CI) 1.56-7.90; P=0.002] and a history of wheeze during the first year of life (OR 2.81; 95% CI 1.16-6.84; P=0.023) were independent explanatory factors for increased FE(NO) , and IgE-positive CMA (OR 3.37; 95% CI 1.03-10.97; P=0.044) and parental smoking (OR 3.41; 95% CI 1.14-10.22; P=0.028) for increased BHR, whereas for IgE-negative CMA, no associations with FE(NO) or BHR were found. In the CMA group, those exposed to CM very early at the maternity hospital, had less BHR (P=0.002). CONCLUSIONS Compared with their controls, children with a history of IgE-positive CMA show signs of airway inflammation, expressed as higher FE(NO) , and more pronounced bronchial responsiveness to histamine at school age. In contrast to IgE-negative CMA, IgE-positive CMA is a significant predictor of increased FE(NO) and BHR at school age. Very early exposure to CM was associated with less BHR.

Abstract
Children who are referred to specialist care with asthma that does not respond to treatment (problematic severe asthma) are a heterogeneous group, with substantial morbidity. The evidence base for management is sparse, and is mostly based on data from studies in children with mild and moderate asthma and on extrapolation of data from studies in adults with severe asthma. In many children with severe asthma, the diagnosis is wrong or adherence to treatment is poor. The first step is a detailed diagnostic assessment to exclude an alternative diagnosis ("not asthma at all"), followed by a multidisciplinary approach to exclude comorbidities ("asthma plus") and to assess whether the child has difficult asthma (improves when the basic management needs, such as adherence and inhaler technique, are corrected) or true, therapy-resistant asthma (still symptomatic even when the basic management needs are resolved). In particular, environmental causes of secondary steroid resistance should be identified. An individualised treatment plan should be devised depending on the clinical and pathophysiological characterisation. Licensed therapeutic approaches include high-dose inhaled steroids, the Symbicort maintenance and reliever (SMART) regimen (with budesonide and formoterol fumarate), and anti-IgE therapy. Unlicensed treatments include methotrexate, azathioprine, ciclosporin, and subcutaneous terbutaline infusions. Paediatric data are needed on cytokine-specific monoclonal antibody therapies and bronchial thermoplasty. However, despite the interest in innovative approaches, getting the basics right in children with apparently severe asthma will remain the foundation of management for the foreseeable future.

Abstract
Food allergy is a potentially severe immune response to a food or food additive. Although a majority of children will outgrow their food allergies, some may have lifelong issues. Food allergies and other atopic conditions, such as asthma, are increasing in prevalence in Western countries. As such, it is not uncommon to note the co-existence of food allergy and asthma in the same patient. As part of the atopic march, many food allergic patients may develop asthma later in life. Each can adversely affect the other. Food allergic patients with asthma have a higher risk of developing life-threatening food-induced reactions. Although food allergy is not typically an etiology of asthma, an asthmatic patient with food allergy may have higher rates of morbidity and mortality associated with the asthma. Asthma is rarely a manifestation of food allergy alone, but the symptoms can be seen with allergic reactions to foods. There may be evidence to suggest that early childhood environmental factors, such as the mother's and child's diets, factor in the development of asthma; however, the evidence continues to be conflicting. All food allergic patients and their families should be counseled on the management of food allergy and the risk of developing co-morbid asthma.

Abstract
OBJECTIVE Current guidelines recommend that egg-allergic patients receive an influenza vaccine skin test before the influenza vaccine. This study evaluated the safety of bypassing the skin test and administering graded doses of influenza vaccine to egg-allergic children. METHODS We conducted a retrospective chart-review study of egg-allergic patients aged 6 months to 18 years who received the vaccine skin test and/or a 2-dose graded influenza vaccine. Between influenza seasons 2002-2003 and 2006-2007, egg-allergic patients underwent a vaccine skin test before influenza vaccine administration. Starting in 2006-2007, the skin test was removed from our protocol and egg-allergic patients received the influenza vaccine in 2 graded doses. All vaccinated patients were observed for adverse reactions. RESULTS Two hundred sixty-one egg-allergic patients were evaluated for influenza vaccine administration, and 171 went on to receive the vaccine. Of the 56 patients who received the skin test before the influenza vaccine, 95% (exact 95% confidence interval [CI]: 85.1-98.9) tolerated the vaccine without a serious adverse reaction. This rate was unchanged after the vaccine skin test was removed from the protocol. Of the 115 patients who received the vaccine without a preceding skin test, 97% (exact 95% CI: 91.3-99.0) tolerated the vaccine without serious adverse reaction. The tolerance rate ratio was 1.01 (95% CI: 0.97-1.06). CONCLUSION The results of our study suggest that egg-allergic patients without anaphylaxis to egg may safely receive the influenza vaccine in a 2-dose, graded fashion without a vaccine skin test.

Abstract
OBJECTIVE To evaluate the relationship between peanut allergy and asthma morbidity in school-age children. STUDY DESIGN The study involved a medical chart review to assess the association of peanut allergy with asthma morbidity in children beyond age 3 years. Peanut allergy was assessed by specific and validated criteria. A Poisson regression model was used to compare the frequency of systemic steroid use and of hospitalization for asthma beyond age 3 years in children with asthma with and without peanut allergy. RESULTS Children with peanut allergy had a 2.32-times greater rate of hospitalization (P = .03) and a 1.59-times greater rate of systemic steroid use (P <.001) after controlling for covariates. CONCLUSIONS Peanut allergy serves as an early marker for asthma morbidity. Early prevention and intervention can improve quality of care.

Abstract
Children suffering from difficult-to-control asthma (DCA) require frequent appointments with their physician, complex treatment regimes and often admissions to hospital. Less than 5% of the asthmatic population suffer this condition. DCA must be correctly characterised to rule out false causes of DCA and requires making a differential diagnosis from pathologies that mimic asthma, comorbidity, environmental and psychological factors, and analysing the factors to determine poor treatment compliance. In true DCA cases, inflammation studies (exhaled nitric oxide, induced sputum, broncho-alveolar lavage and bronchial biopsy), pulmonary function and other clinical aspects can classify DCA into different phenotypes which could make therapeutic decision-making easier.

Abstract
BACKGROUND Allergic disorders are characterized by an increase in the Th2 cytokines IL-4, IL-5 and IL-13, produced primarily by Th2 cells. These cells are marked by the expression of CRTh2 (chemoattractant receptor-homologous molecule expressed on Th2 cells), a receptor for prostaglandin D(2). As genetic variation plays a significant role in the predisposition for allergic disorders, we investigated the influence of single nucleotide polymorphisms (SNPs) in CRTh2. METHODS In a large study population of German children (n = 4264) from the International Study of Asthma and Allergy in Children (ISAAC II), six polymorphisms in CRTh2 were genotyped. Statistical analyses were performed using single SNP and haplotype analyses. RESULTS Uncorrected associations among -6373G>A, +1431G>C and +1538A>G were observed with a number of allergic phenotypes (P < 0.05). After correction, association between +1431C and specific IgE to food allergens remained significant (P = 0.04). Associations of haplotype (H)3 (containing +1538G) with reduced risk for asthma and H2 (containing +1431C) with increased risk for specific IgE to food allergens also remained significant after correction for multiple testing (P = 0.004). CONCLUSIONS Genetic variation within CRTh2 modifies the development of allergic sensitization and asthma in a population of German children.

Abstract
PURPOSE OF REVIEW Allergic disorders represent a serious public health problem in children. The chronic nature of these diseases and the fear of known side effects of synthetic drugs influence many families to seek complementary and alternative medicine. This review focuses on traditional Chinese medicine (TCM) herbal products and acupuncture for treating pediatric allergies. RECENT FINDINGS Given the general safety profile and reputed efficacy, TCM are well received by the general population. However, compared with the long human history and popularity of the use of TCM, research into its efficacy and safety is still in its infancy. In the last 2-3 years, there have been more controlled studies of TCM for allergic asthma and allergic rhinitis. Several publications including ours indicate that some TCM herbal formulas are well tolerated and produce some level of efficacy. Some herbal formulas also showed beneficial immunomodualtory effects. Several preclinical studies demonstrated that the food allergy herbal formula-2 was effective in protecting against peanut anaphylaxis in animal models. Two TCM products have entered clinical trials in the United States for treating asthma and food allergy, respectively. Both of these trials include children. SUMMARY Recent studies indicate that TCM therapy including herbal medicines and acupuncture for allergic disorders in children is well tolerated. There are also promising clinical and objective improvements. More controlled clinical studies are encouraged.

Abstract
BACKGROUND The atopic march is well documented, but the interrelationship of food allergy (FA) and asthma is not well understood. OBJECTIVE The aim of this study was to examine the strength of the association and temporal relationships between FA and asthma. METHODS This analysis included 271 children >or=6 years (older group) and 296 children <6 years (younger group) from a family-based FA cohort in Chicago, IL. Asthma was determined by parental report of physician diagnosis. FA status was determined based on the type and timing of clinical symptoms after ingestion of a specific food, and results of prick skin test (Multi-Test II) and allergen-specific IgE (Phadia ImmunoCAP). Analyses were carried out using logistic regression accounting for important covariates and auto-correlations among siblings. Kaplan-Meier curves were used to compare the time to onset of asthma with the FA status. RESULTS Symptomatic FA was associated with asthma in both older [odds ratio (OR)=4.9, 95% confidence interval (CI): 2.5-9.5] and younger children (OR=5.3, 95% CI: 1.7-16.2). The association was stronger among children with multiple or severe food allergies, especially in older children. Children with FA developed asthma earlier and at higher prevalence than children without FA (Cox proportional hazard ratio=3.7, 95% CI: 2.2-6.3 for children >or=6 years, and hazard ratio=3.3, 95% CI: 1.1-10 for children <6 years of age). No associations were seen between asymptomatic food sensitization and asthma. CONCLUSIONS Independent of markers of atopy such as aeroallergen sensitization and family history of asthma, there was a significant association between FA and asthma. This association was even stronger in subjects with multiple food allergies or severe FA.
