Epidemiology of Paediatric Italian Food Allergy: Results of the EPIFA study. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. GLOBAL 2024; 3:100246. [PMID: 38655562 PMCID: PMC11035069 DOI: 10.1016/j.jacig.2024.100246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 01/14/2024] [Accepted: 01/27/2024] [Indexed: 04/26/2024]
Abstract
Background Updated epidemiologic data are important for defining effective public health strategies for pediatric food allergy (FA). Objective The Epidemiology of Paediatric Italian Food Allergy (EPIFA) study was designed to investigate the epidemiology of pediatric FA in one of the most heavily populated Italian regions. Methods A retrospective cohort study was performed in collaboration with family pediatricians aimed at investigating the epidemiology of Italian pediatric FA during 2009 to 2021. Family pediatricians in the Campania region were invited to use the Google Forms platform for online compilation of data forms. Data forms were reviewed by experienced pediatric allergists at the coordinating center. Results A total population of 105,151 subjects (aged 0-14 years) was screened during the study period. Data from 752 FA patients were evaluated. A progressive increase in FA incidence and prevalence was observed from 2009 to 2021, with a relative increase up to 34% and 113.6%, respectively, at the end of study period. The relative increase in FA prevalence was higher in the 0-3-year-old age group in the same study period (+120.8%). The most frequent allergens were cow's milk, hen's egg, and nuts. Conclusion The results of the EPIFA study showed an increase in pediatric FA incidence and prevalence from 2009 to 2021 in Italy. These results underline the necessity of new effective strategies for preventing and managing these conditions.

Abstract
In 2014, the European Academy of Allergy and Clinical Immunology (EAACI) published the first systematic review that summarized the prevalence of food allergy (FA) and food sensitization in Europe for studies published 2000-2012. However, only summary estimates for tree nut allergy (TNA) were feasible in that work. In the current update of that systematic review, we summarized the prevalence of tree nut allergy/sensitization to individual tree nuts. Six databases were searched for relevant papers published 2012-2021 and 17 eligible studies were added to the 15 studies already identified between 2000 and 2012, giving a total of 32 studies. Of the investigated tree nuts, meta-analysis was possible for hazelnut, walnut, almond, and in few cases, for cashew, and Brazil nut. The lifetime self-reported prevalence was 0.8% (95% CI 0.5-1.1) for hazelnut and 0.4% (0.2-0.9) for walnut. The point self-reported prevalence was 4.0% (2.9-5.2) for hazelnut, 3.4% (2.0-4.9) for Brazil nut, 2.0% (1.1-2.9) for almond, and 1.8% (1.1-2.5) for walnut. Point prevalence of food challenge-confirmed TNA was 0.04% (0.0-0.1) for hazelnut and 0.02% (0.01-0.1) for walnut. Due to paucity of data, we could not identify any meaningful and consistent differences across age groups and European regions.

Abstract
In 2014, the European Academy of Allergy and Clinical Immunology published prevalence estimates for food allergy (FA) and food sensitization (FS) to the so-called eight big food allergens (i.e. cow's milk, egg, wheat, soy, peanut, tree nuts, fish and shellfish) in Europe for studies published between 2000 and 2012. The current work provides 10-year updated prevalence estimates for these food allergens. A protocol was registered on PROSPERO before starting the research (reference number CRD42021266657). Six databases were searched for studies published 2012-2021, added to studies published up to 2012, resulting in a total of 93 studies. Most studies were graded as at moderate risk of bias. The overall pooled estimates for all age groups of self-reported lifetime prevalence were as follows: cow's milk (5.7%, 95% confidence interval 4.4-6.9), egg (2.4%, 1.8-3.0), wheat (1.6%, 0.9-2.3), soy (0.5%, 0.3-0.7), peanut (1.5%, 1.0-2.1), tree nuts (0.9%, 0.6-1.2), fish (1.4%, 0.8-2.0) and shellfish (0.4%, 0.3-0.6). The point prevalence of food challenge-verified allergy were as follows: cow's milk (0.3%, 0.1-0.5), egg (0.8%, 0.5-1.2), wheat (0.1%, 0.01-0.2), soy (0.3%, 0.1-0.4), peanut (0.1%, 0.0-0.2), tree nuts (0.04%, 0.02-0.1), fish (0.02%, 0.0-0.1) and shellfish (0.1%, 0.0-0.2). With some exceptions, the prevalence of allergy to common foods did not substantially change during the last decade; variations by European regions were observed.

Abstract
BACKGROUND This retrospective study was designed in order to compare the usefulness of skin prick tests, serological specific IgE tests and solid phase immunoassays in the diagnosis of infantile allergic diseases. METHODS Two hundred infants with allergic diseases (120 infants with eczema and 80 infants with asthma), diagnosed in the Pediatric Clinic of our hospital between June of 2011 and June of 2016, were selected to participate in the study. 100 healthy infants were included in a control group. All infants received a skin prick test, a serological specific IgE test or a solid phase immunoassay. A total of 38 allergens were used for the infants receiving skin prick test. The IgE in the serum samples of infants was detected by immunoblotting. And, allergens were detected by solid phase immunoassay in the infants receiving solid phase immunoassay. The positive predictive value, negative predictive value, specificity and sensitivity for these 3 diagnostic methods were analyzed after generating a ROC curve. RESULTS In the eczema group, the AUCs (the area under the ROC curve) for skin prick test, serological specific IgE test and solid phase immunoassay were 0.8685±0.0187, 0.8137±0.024 and 0.9682±0.0358, respectively. The sensitivities for skin prick test, serological specific IgE test and solid phase immunoassay were 85.70%, 83.62% and 88.72%, respectively. And, the specificities were 74%, 68% and 83%, respectively. The positive predictive values were 87.27%, 92.37% and 90.00%; and the negative predictive values were 57.04%, 51.11% and 78.15%, respectively. In the asthma group, the AUCs for skin prick test, serological specific IgE test and solid phase immunoassay were 0.8186±0.0161, 0.8037±0.0241 and 0.952±0.0421, respectively. The sensitivities for skin prick test, serological specific IgE test and solid phase immunoassay were 84.70%, 88.62% and 96.72%, respectively. The specificities were 76%, 64% and 81%, respectively; the positive predictive values were 81.34%, 85.59% and 84.54%, respectively. The negative predictive values were 69.29%, 67.14% and 70.08%, respectively. CONCLUSIONS While all three methods were effective in the diagnosis of infantile allergic diseases, the solid phase immunoassay was superior to the other two methods, as evidenced by the obtained values and we recommend it for clinical application as a goal standard.

Abstract
Food allergy (FA) is increasingly reported in Europe, however, the latest prevalence estimates were based on studies published a decade ago. The present work provides the most updated estimates of the prevalence and trends of FA in Europe. Databases were searched for studies published between 2012 and 2021, added to studies published up to 2012. In total, 110 studies were included in this update. Most studies were graded as moderate risk of bias. Pooled lifetime and point prevalence of self-reported FA were 19.9% (95% CI 16.6-23.3) and 13.1% (95% CI 11.3-14.8), respectively. The point prevalence of sensitization based on specific IgE (slgE) was 16.6% (95% CI 12.3-20.8), skin prick test (SPT) 5.7% (95% CI 3.9-7.4), and positive food challenge 0.8% (95% CI 0.5-0.9). While lifetime prevalence of self-reported FA and food challenge positivity only slightly changed, the point prevalence of self-reported FA, sIgE and SPT positivity increased from previous estimates. This may reflect a real increase, increased awareness, increased number of foods assessed, or increased number of studies from countries with less data in the first review. Future studies require rigorous designs and implementation of standardized methodology in diagnosing FA, including use of double-blinded placebo-controlled food challenge to minimize potential biases.

Abstract
Background: Peanuts (PN) and tree nuts (TN) are major causes of anaphylaxis worldwide. We aimed to determine the clinical and demographic characteristics associated with anaphylaxis in patients sensitized to PN and/or TN in a Mediterranean population. Methods: We conducted a retrospective study, which included 198 patients allergic to PN and/or TN (allergy symptoms plus specific immunoglobulin E [sIgE] sensitization), evaluated in consultations from January 2015 to December 2020. Univariate analysis and multivariate logistic regression models were developed, including demographic, clinical, and laboratory data as independent variables, and anaphylaxis to each PN and/or TN as a dependent variables. Results: Anaphylaxis was associated with an earlier age of onset of allergy to PN, cashew and/or pistachio, and pine nut allergy but not to other TN allergies. Gender, atopic comorbidities, and cofactors were not associated with PN and/or TN anaphylaxis. Anaphylaxis to PN, cashew and/or pistachio, and pine nut were associated with reactivity to a fewer number of PN and/or TN foods. Although sIgE sensitization to lipid transfer proteins (LTP) was highly prevalent in our population, only seed storage protein (SSP) positivity was associated with anaphylaxis in PN allergy. The absence of pathogenesis-related protein family 10 sensitization correlated with PN and hazelnut anaphylaxis. A higher level of sIgE to almond extract predicted anaphylaxis but the level of sIgE to other PN and/or TN extracts did not predict it. Conclusion: The high prevalence of sensitization to the pan-allergen LTP did not seem to have a significant impact in PN and/or TN allergy severity in our study. Instead, other factors, such as early age of onset and positivity for SSPs, seem to strongly associate with anaphylaxis to specific PN and/or TN. These findings may contribute to individual risk assessment in these populations.

Abstract
Food allergies are a leading cause of anaphylaxis, and cellular mechanisms involving antigen presentation likely play key roles in their pathogenesis. However, little is known about the response of specific antigen-presenting cell (APC) subsets to food allergens in the setting of food allergies. Here, we show that in peanut-allergic humans, peanut allergen drives the differentiation of CD209+ monocyte-derived dendritic cells (DCs) and CD23+ (FcєRII) myeloid dendritic cells through the action of allergen-specific CD4+ T cells. CD209+ DCs act reciprocally on the same peanut-specific CD4+ T cell population to reinforce Th2 cytokine expression in a positive feedback loop, which may explain the persistence of established food allergy. In support of this novel model, we show clinically that the initiation of oral immunotherapy (OIT) in peanut-allergic patients is associated with a decrease in CD209+ DCs, suggesting that breaking the cycle of positive feedback is associated with therapeutic effect.

Abstract
Hazelnuts commonly elicit allergic reactions starting from childhood and adolescence, with a rare resolution over time. The definite diagnosis of a hazelnut allergy relies on an oral food challenge. The role of component resolved diagnostics in reducing the need for oral food challenges in the diagnosis of hazelnut allergies is still debated. Therefore, three electronic databases were systematically searched for studies on the diagnostic accuracy of specific-IgE (sIgE) on hazelnut proteins for identifying children with a hazelnut allergy. Studies regarding IgE testing on at least one hazelnut allergen component in children whose final diagnosis was determined by oral food challenges or a suggestive history of serious symptoms due to a hazelnut allergy were included. Study quality was assessed by the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Eight studies enrolling 757 children, were identified. Overall, sensitivity, specificity, area under the curve and diagnostic odd ratio of Cor a 1 sIgE were lower than those of Cor a 9 and Cor a 14 sIge. When the test results were positive, the post-test probability of a hazelnut allergy was 34% for Cor a 1 sIgE, 60% for Cor a9 sIgE and 73% for Cor a 14 sIgE. When the test results were negative, the post-test probability of a hazelnut allergy was 55% for Cor a 1 sIgE, 16% for Cor a9 sIgE and 14% for Cor a 14 sIgE. Measurement of IgE levels to Cor a 9 and Cor a 14 might have the potential to improve specificity in detecting clinically tolerant children among hazelnut-sensitized ones, reducing the need to perform oral food challenges.

Abstract
Background & aims The objective of the present study was to determine, for the first time, the prevalence and clinical features of food allergy in Portuguese adolescents. Methods Cross-sectional study performed in various secondary schools in central Portugal. Randomly selected adolescents replied to a validated food allergy questionnaire. Those who reported an adverse food reaction were seen at participating hospitals, where clinical history was taken, skin prick (SPT) and prick-prick skin (SPPT) tests were performed, and food allergen-specific IgE levels (sIgE) were determined. An open oral challenge was performed in selected cases. Cases of positive clinical history of immediate (up to 2 h after ingestion) reaction in association with positive food sIgE levels and/or SPT were classified as IgE-associated probable food allergy and as confirmed IgE-mediated food allergy if food challenges were positive. Cases of positive clinical history of delayed (more than 2 h after ingestion) and negative food sIgE levels independently of positive SPT or SPPT results, were classified as non-IgE associated probable food allergy. Results The prevalence of probable food allergy in Portuguese adolescents was 1.41% (95% CI: 0.90–2.03%), with fresh fruits, shellfish, nuts, and peanut as the most frequently implicated foods. IgE-mediated probable food allergy occurred in 1.23% (95% CI: 0.67–1.72%) of cases, with fresh fruits, shellfish, and nuts mainly involved. Cutaneous symptoms were most frequently reported. Conclusions The prevalence of probable food allergies in Portuguese adolescents is low, is mostly related to fresh fruits, shellfish, nuts, and peanut, and most frequently involves cutaneous symptoms.

Pediatr Allergy Immunol 2020; 31:380-387. [PMID: 31943386 DOI: 10.1111/pai.13212] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Revised: 11/10/2019] [Accepted: 12/20/2019] [Indexed: 01/12/2023]
Abstract
BACKGROUND Despite a relatively high risk for allergic reactions, including anaphylaxis, schools are not sufficiently trained and confident in handling children suffering from food allergy. This study aimed to measure the improvement of school personnel's self-efficacy in managing food allergy and anaphylaxis at school after a specific multidisciplinary training course. METHODS A total of 592 teachers and school caretakers completed the School Personnel Self-Efficacy-Food Allergy and Anaphylaxis Questionnaire (S.PER.SE-FAAQ) before and after the course. The median difference, along with I quartile and III quartile, in scores between baseline and post-intervention assessment was calculated. A conditional regression tree was fitted for each outcome measured after the educational intervention. RESULTS At baseline, school personnel reported low self-efficacy in anaphylaxis management (AM), especially in recognizing anaphylaxis symptoms and administering proper drugs. After the specific multidisciplinary training course, all scores improved. AM scores particularly showed a significant increase. School personnel's post-training self-efficacy was found to be related to initial levels. Some indicative threshold values emerged. Remarkably, participants with a low self-efficacy at baseline seemed to particularly benefit from the training. CONCLUSIONS Results highlighted the effectiveness of specific multidisciplinary training courses in improving teachers' and school caretakers' self-efficacy in managing food allergy and anaphylaxis. The S.PER.SE-FAAQ is confirmed to be an easy and helpful tool to assess the level of food allergy and anaphylaxis management in the school staff and training effectiveness.

Abstract
PURPOSE OF REVIEW In recent decades, food allergy has become an increasing concern for families, clinicians, and policymakers. This review aims to summarize what is currently known about the epidemiology and population-level burden of IgE-mediated food allergy, including its effects on quality of life. RECENT FINDINGS Prevalence surveys, healthcare utilization data, and findings from longitudinal cohort studies across the globe indicate that food allergy imposes a growing societal burden. Worryingly, recent data indicate that food allergies may be more prevalent among adult populations than previously acknowledged, with many reported cases of adult-onset allergies. While it remains unclear how much of the current population-level burden of disease results from true, IgE-mediated allergy, as much epidemiological data does not incorporate clinical confirmation of disease prevalence-it is clear that affected individuals suffer impairments in their quality of life and incur substantial economic costs-beyond the physical health burden imposed by anaphylaxis.

Abstract
BACKGROUND There is little understanding of the mechanisms by which food allergy (FA) develops into persistent disease, or by which symptoms it regresses. Food allergy is a major health problem in developed countries, where the prevalence reaches up to 6% in children and 3% in the adult population. OBJECTIVE Children with food allergy remission (FAR) and those without FAR below five years of age, were compared 7-10 years with respect to clinical data and expression of glycoprotein A repetitions predominant (GARP) on peripheral blood mononuclear cells. METHODS Forty children with FAR and 40 children without FAR at age 7-10, in whom FA was previously diagnosed at age below five years were evaluated. In this prospective study, demographic and clinical data were taken, patients were classified as atopic based on history and serum specific IgE (sIgE) for a specific allergen. Blood samples were obtained from all patients to assess expression of GARP. RESULTS We observed higher expression of GARP in children with FAR compared to children without FA (p=0.005); optimal cut-off for GARP prediction of the remission was 20.1%. Children with FAR and food-specific IgE in serum had higher expression of GARP compared to children with low food specific IgE (<0.35kU/L). Keeping pets at home decreased, and presence of allergic rhinitis increased ORs for high expression of GARP (hGARP) in our patients. CONCLUSION hGARP (>20.1%) is related with FAR in school children. Allergic rhinitis, and pets at home modify this effect of GARP. Children with allergic rhinitis have less chance of developing remission despite maintaining immune tolerance (hGARP); quite the opposite case with pets at home.

Abstract
Gluten-related disorders are very common in pediatric patients. Wheat allergy is triggered by an immunoglobulin E (IgE)-dependent mechanism; its prevalence varies according to the age and region, and in Europe has been estimated to be lower than 1%. Many studies investigated the potential role of several external factors that can influence the risk to developing wheat allergy, but results are still inconclusive. It can be responsible for several clinical manifestations depending on the route of allergen exposure: food-dependent exercise-induced anaphylaxis (FDEIA), occupational rhinitis or asthma (also known as baker’s asthma), and contact urticaria. The prognosis of IgE-mediated wheat allergy in children is generally favorable, with the majority of children becoming tolerant by school age. Patients who experienced an anaphylactic reaction prior to 3 years of age and patients with higher level of wheat- or ω-5 gliadin-specific IgE antibodies seem to be at higher risk of persistent wheat allergy. The current management of patients is dietary avoidance. Nowadays, oral immunotherapy has been proposed for wheat allergy with promising results, even if further studies are necessary to establish the best protocol in order to promote tolerance in wheat-allergic children.

Abstract
Background: Pru p 3 is the major allergen of the peach and belongs to the LTP family. Pru p 3 sensitization has been associated with severe allergic symptoms after eating LTP-containing foods. However, a previous experience partially downsized the potential danger of Pru p 3 sensitization in a group of adult rhinitics. This study aimed to evaluate the real impact of Pru p 3 sensitization in children in a real-world setting. Methods: 82 consecutive paediatric patients (55 males and 27 females, mean age 8.19±4.23 years) with allergic rhinitis due to Parietaria pollen allergy and sensitization to Pru p 3, documented by ISAC test, were evaluated. Serum IgE was measured by ImmunoCap method. Allergic symptoms occurring after ingesting LTP-containing foods were considered and scored as oral allergy syndrome, food allergy, and anaphylaxis. Results: About one-quarter of Pru p 3-sensitized children reported anaphylaxis after ingesting LTP-containing foods, about half reported food allergy or oral allergy syndrome. Only ¼ was merely sensitized. Conclusions: Pru p 3 sensitization deserves careful attention in children contrary to what might occur in adult patients. It could depend on the age and the serum IgE level. Thus, Pru p 3 sensitization should be adequately interepreted and managed in clinical practice. (www.actabiomedica.it)

Abstract
INTRODUCTION Cow's milk is a frequent trigger of allergic reactions in childhood. Cow's milk proteins can be present in pharmaceutical excipients. METHODS We have analyzed paediatric literature on allergic reactions to cow's milk proteins in medication, focusing on the different routes of administration (inhaled, parental and oral). RESULTS Dry-powder inhalers may contain lactose as excipient. Lactose can be rarely contaminated with milk proteins and it may induce allergic reactions in patients with cow's milk allergy. Case reports have described immediate hypersensitivity reactions to methylprednisolone sodium succinate 40 mg injection, a formulation that contains lactose as excipient. Some cases of anaphylaxis after receiving diphteria-tetanus-pertussis vaccine injection in children allergic to milk have been reported. Cow's milk proteins can be detected also in oral polio vaccine, certain probiotics and lactulose syrup. CONCLUSIONS We suggest caution in administration of pharmaceuticals containing milk allergens in children allergic to milk.

Abstract
AIM The ten-year Finnish national allergy programme was launched in 2008 to lessen the disease and psychological burden of allergy. This study assessed the prevalence of parent-reported food allergies requiring avoidance diets at primary school in children aged six and seven years. METHODS The cohort comprised 1937 children (51% boys) who started primary school in Tampere, Finland, in August 2016. School health nurses charted parent-reported, doctor-diagnosed food allergies requiring avoidance diets as part of the routine health examination. RESULTS We found that 127 (6.6%) children had parent-reported, doctor-diagnosed allergies to at least one food and 37 (1.9%) were allergic to basic foods, namely cows' milk, wheat and one other grain. All required an avoidance diet. The figure did not differ significantly from the 2.7% and 2.5% found by studies of this age group in 2009 and 2013, respectively. Allergies to fresh fruit and vegetables decreased from 5.8% in 2009 to 3.6% in 2016. CONCLUSION We studied the national allergy programme that started in 2008 and found that there was a nonsignificant overall decrease in the number of children aged six to seven years on avoidance diets for allergies between 2009 and 2016. The only allergies that showed significant decreases were fresh fruit and vegetables.

Abstract
Background The prevalence of adverse food reactions (AFR) has been increasing in the western world. Clinical manifestations are diversified and it may not be possible to clinically discriminate between IgE and non-IgE mediated AFR. In Portugal, the prevalence of AFR and food allergies in children is not known. Thus, the objectives of this study were to determine the prevalence of AFR in central Portugal. Methods Point prevalence study in 3–11 year-old schoolchildren from Central Portugal. Food-related questionnaires, skin prick tests (SPT) with foods and determination of food-specific IgE levels were performed. Results Of 4045 schoolchildren, 2474 (61.2%) accepted to be included in the study. Global prevalence of AFR was 7.1% (95% CI 6.2–8.1), based upon the initial questionnaire, 4.6% (95% CI 3.9–5.5), based upon a confirmatory questionnaire and the prevalence of probable food allergy (IgE-associated AFR: positive history + positive SPT and/or positive specific IgE) was 1.4% (95% CI 0.9–1.9). Most frequently implicated foods were fresh fruits, fish and egg. A first episode at an earlier age, mucocutaneous and anaphylactic reactions were more frequent in IgE-associated AFR. Conclusions The prevalence of probable food allergy in 3–11 year old Portuguese children from central Portugal is low and parents over-report its frequency. Most frequently implicated foods were fresh fruit and fish. Immediate type, polysymptomatic, and more severe reactions may commence at an earlier age and be more frequent in IgE-associated than in non-IgE associated reactions.

Abstract
Objective To compare fathers' and mothers' perceptions of the impact and severity of their child's food allergy and their levels of involvement in allergy-related care. Methods One hundred parents of children with food allergy (50 mother-father pairs) rated the severity of their child's food allergies and completed the Food Allergy Impact Scale. A subset of 52 parents reported how often they engaged in food allergy-related care. Results Mothers reported more impact than fathers for meal preparation, family social activities, and stress and free time, and significantly greater involvement in allergy-related care. Fathers who reported more frequent medical appointment attendance perceived meal preparation as being significantly more impacted by food allergy than fathers who were less involved. Conclusions Fathers who are less involved may be buffered from experiencing the impact of their child's health condition. Differences in involvement rather than other gender differences may explain discrepancies in mothers' and fathers' illness perceptions.

Abstract
Background In view of the increasing prevalence of food allergies, there has been an associated increase in frequency of situations requiring an emergency response for anaphylaxis at the home, childcare facilities and educational institutions. Objective To clarify the situation of adrenaline auto-injector administration in nursery/kindergarten/school, we carried out a questionnaire survey on pediatric physicians in Western Japan. Methods In 2015, self-reported questionnaires were mailed to 421 physicians who are members of the West Japan Research Society Pediatric Clinical Allergy and Shikoku Research Society Pediatric Clinical Allergy. Results The response rate was 44% (185 physicians) where 160 physicians had a prescription registration for the adrenaline auto-injector. In the past year, 1,330 patients were prescribed the adrenaline auto-injector where 83 patients (6% of the prescribed patients) actually administered the adrenaline auto-injector, of which 14 patients (17% of the administered patients) self-administered the adrenaline auto-injector. “Guardians” at the nursery/kindergarten and elementary school were found to have administered the adrenaline auto-injector the most. Among 117 adrenaline auto-injector prescription-registered physicians, 79% had experienced nonadministration of adrenaline auto-injector at nursery/kindergarten/school when anaphylaxis has occurred. The most frequent reason cited for not administering the adrenaline auto-injector was “hesitation about the timing of administration.” Conclusion If the adrenaline auto-injector was administered after the guardian arrived at the nursery/kindergarten/school, it may lead to delayed treatment of anaphylaxis in which symptoms develop in minutes. Education and cooperation among physicians and nursery/kindergarten/school staff will reduce the number of children suffering unfortunate outcomes due to anaphylaxis.

Abstract
This review focuses key advances in different pediatric fields that were published in Italian Journal of Pediatrics and in international journals in 2015. Weaning studies continue to show promise for preventing food allergy. New diagnostic tools are available for identifying the allergic origin of allergic-like symptoms. Advances have been reported in obesity, short stature and autoimmune endocrine disorders. New molecules are offered to reduce weight gain and insulin-resistance in obese children. Regional investigations may provide suggestions for preventing short stature. Epidemiological studies have evidenced the high incidence of Graves' disease and Hashimoto's thyroiditis in patients with Down syndrome. Documentation of novel risk factors for celiac disease are of use to develop strategies for prevention in the population at-risk. Diagnostic criteria for non-celiac gluten sensitivity have been reported. Negative effect on nervous system development of the supernumerary X chromosome in Klinefelter syndrome has emerged. Improvements have been made in understanding rare diseases such as Rubinstein-Taybi syndrome. Eltrombopag is an effective therapy for immune trombocytopenia. Children with sickle-cell anemia are at risk for nocturnal enuresis. Invasive diseases caused by Streptococcus pyogenes are still common despite of vaccination. No difference in frequency of antibiotic prescriptions for acute otitis media between before the publication of the national guideline and after has been found. The importance of timing of iron administration in low birth weight infants, the effect of probiotics for preventing necrotising enterocolitis and perspectives for managing jaundice and cholestasis in neonates have been highlighted. New strategies have been developed to reduce the risk for relapse in nephrotic syndrome including prednisolone during upper respiratory infection. Insights into the pathophysiology of cerebral palsy, arterial ischemic stroke and acute encephalitis may drive advances in treatment. Recommendations on breastfeeding and complementary feeding have been updated. Novel treatments for rhabdomyosarcoma should be considered for paediatric patients. Control of risk factors for bronchiolitis and administration of pavilizumab for preventing respiratory syncytial virus infection may reduce hospitalization. Identification of risk factors for hospitalization in children with wheezing can improve the management of this disease. Deletions or mutations in genes encoding proteins for surfactant function may cause diffuse lung disease.

Abstract
BACKGROUND Food allergy affects up to 4-7% European schoolchildren. Studies identified important shortcomings on food allergy and anaphylaxis management in schools. In social cognitive theory, personal beliefs in own capabilities influence choices, effort levels, perseverance and performance accomplishments. This study aimed to investigate school personnel's self-efficacy in managing food allergy and anaphylaxis, providing a valid instrument to deeply understand how to support schools to effectively manage students at risk of food reactions. METHODS A total of 440 schoolteachers and caretakers from north-east Italy completed a questionnaire assessing self-efficacy in managing food allergy and anaphylaxis at school. Exploratory factor analysis was performed. Factors' internal consistency was evaluated using Cronbach's alpha. Factors' scores were estimated using Bartlett approach, and kernel density estimate of distributions was provided. Descriptive statistics explored school personnel's self-efficacy. A regression model assessed the influence of gender, school, job and previous experience. RESULTS Two factors emerged from exploratory factor analysis related to anaphylaxis management (AM) and food allergy management (FAM). The two subscales both showed good internal consistency. School personnel showed lower self-efficacy in recognizing symptoms, administering drugs and guaranteeing full participation to extra-curricular activities to food-allergic students. Participants who previously had food-allergic students showed a significantly increased self-efficacy in AM and a significantly decreased self-efficacy in FAM. CONCLUSIONS The study supports the use of self-efficacy scale to identify specific areas where teachers' confidence in their ability to care for food-allergic students is especially weak. This would empower the development of training programs specifically tailored to the needs of teachers and caregivers.

Abstract
This review explores the relationship between food allergy and asthma. They can share the same risk factors, such as parental allergy, atopic eczema, and allergen sensitization, and they often coincide in the same child. Coexistence may negatively influence the severity of both conditions. However, it remains to be determined whether food allergy may directly affect asthma control. An early food sensitization in the first year of life can predict the onset of asthma. Furthermore, asthmatic symptoms could rarely be caused by ingestion or inhalation of the offending food. Asthma caused by food allergy is severe and may be associated with anaphylactic symptoms. Therefore, an accurate identification of the offending foods is necessary in order to avoid exposure. Patients should be instructed to treat asthmatic symptoms quickly and to use self-injectable epinephrine.

Abstract
Major advances in the conduct of pediatric practice have been reported in the Italian Journal of Pediatrics in 2014. This review highlights developments in allergy, gastroenterology, infectious diseases, neonatology, nutrition, oncology and respiratory tract illnesses. Investigations endorse a need to better educate guardians and improve nutritional management in food allergy. Management of hyperbilirubinemia in neonates and of bronchiolitis have been improved by position statements of scientific societies. Novel treatments for infant colic and inflammatory bowel diseases have emerged. Studies suggest the diagnostic utility of ultrasonography in diagnosing community-acquired pneumonia. Progress in infectious diseases should include the universal varicella vaccination of children. Recommendations on asphyxia and respiratory distress syndrome have been highlighted in neonatology. Studies have evidenced that malnutrition remains a common underestimated problem in developing countries, while exposure to cancer risk factors in children is not negligible in Western countries. Advances in our understanding of less common diseases such as cystic fibrosis, plastic bronchitis, idiopathic pulmonary hemosiderosis facilitate diagnosis and management. Researches have led to new therapeutic approaches in patent ductus arteriosus and pediatric malignancies.

Abstract
Tree nuts are one of the most common foods causing acute allergic reactions and nearly all tree nuts have been associated with fatal allergic reactions. Despite their clinical importance, tree nut allergy epidemiology remains understudied and the prevalence of tree nut allergy in different regions of the world has not yet been well characterised. We aimed to systematically review the population prevalence of tree nut allergy in children and adults. We searched three electronic databases (OVID MEDLINE, EMBASE and PubMed) from January 1996 to December 2014. Eligible studies were categorised by age, region and method of assessment of tree nut allergy. Of the 36 studies identified most were in children (n = 24) and from Europe (n = 18), UK (n = 8) or USA (n = 5). Challenge-confirmed IgE-mediated tree nut allergy prevalence was less than 2 % (although only seven studies used this gold standard) while probable tree nut allergy prevalence ranged from 0.05 to 4.9 %. Prevalence estimates that included oral allergy syndrome (OAS) reactions to tree nut were significantly higher (8-11.4 %) and were predominantly from Europe. Prevalence of individual tree nut allergies varied significantly by region with hazelnut the most common tree nut allergy in Europe, walnut and cashew in the USA and Brazil nut, almond and walnut most commonly reported in the UK. Monitoring time trends of tree nut allergy prevalence (both overall and by individual nuts) as well as the prevalence of OAS should be considered given the context of the overall recent rise in IgE-mediated food allergy prevalence in the developed world.

Abstract
The present study investigated the current state of unnecessary children food allergy accommodation and the medical efforts to confirm the existence of food allergies in school lunch service kitchens in Okinawa, Japan, including kitchens accommodating food allergy students by requiring medical documentation at the start and during provisions being made (Double Diagnosis), requiring medical documentation at the start only (Single Diagnosis), and with no medical documentation (Non-Diagnosis). Unnecessary accommodations are being made to unconfirmed food allergy students, wherein the more medical consultation was required, the lower the food allergy incident rate was and the more food allergens were diagnosed (Non-Diagnosis > Single Diagnosis > Double Diagnosis). This study suggests the possibility that unconfirmed food allergy students may be receiving unnecessary food allergy accommodations per school lunches, and the number of unnecessary food allergy provisions being made could be reduced by requiring medical documentation at the start and during these provisions.

Abstract
Weaning (or introduction of complementary feeding) is a special and important moment in the growth of a child, both for the family and the infant itself, and it can play a major role in the child’s future health. Throughout the years, various weaning modes have come in succession, the latest being baby-led weaning; the timing for introducing foods and the requirements of which sort of nutrient for weaning have also changed over time. Furthermore, the role played by nutrition, especially in the early stages of life, for the onset of later non-communicable disorders, such as diabetes, obesity or coeliac disease has also been increasingly highlighted. Members of Italian Society of Gastroenterology, Hepathology and Pediatric Nutrition (SIGENP) and the Italian Society of Allergology and Pediatric Immunology (SIAIP) Emilia Romagna here propose a practical approach for pediatricians to deal with daily practice. The four main areas for discussion were weaning in relation with the onset of allergic diseases, coeliac disease, diabetes and metabolic syndrome, the nutrition requirements to take into account for assessing the diet of infants under one year of age and about the practice of baby-led weaning focusing on limits and benefits, respectively.

Järvenpää J, Paassilta M, Salmivesi S, Sannisto T, Niitty S, Korppi M. Stability of parent-reported food allergy in six and 7-year-old children: the first 5 years of the Finnish allergy programme. Acta Paediatr 2014; 103:1297-300. [PMID: 25274459 DOI: 10.1111/apa.12809] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2014] [Revised: 09/04/2014] [Accepted: 09/17/2014] [Indexed: 11/30/2022]
Abstract
AIM The Finnish national allergy programme was introduced in 2008 to decrease the burden of allergy in the population. This study, carried out in 2013, evaluated the prevalence of parent-reported food allergies, treated with an avoidance diet until early school age, and discussed the rates in relation to those found in an identical study in 2009. METHODS School health nurses used a structured questionnaire to interview the parents of 1653 children aged of six or seven in the first year of elementary school. The criterion for a parent-reported food allergy was that the parents considered it necessary for their child to follow an avoidance diet at school. RESULTS In 2013, 6.1% of the children were allergic to at least one food and 2.5% of the children were allergic to basic foods, such as cows' milk, eggs and wheat, compared with 2.7% in 2009. A significant decrease was seen in allergies to nuts, fruits and vegetables. CONCLUSION Parent-reported allergies to basic foods, such as cow's milk, eggs and wheat, remained rather stable in first graders of elementary schools during the first 5 years of the Finnish national allergy programme, but allergies to nuts, fruits and vegetables decreased.

Abstract
Allergy to cow's milk, egg, wheat, soy, peanut, tree nuts, fish, and shellfish constitutes the majority of food allergy reactions, but reliable estimates of their prevalence are lacking. This systematic review aimed to provide up-to-date estimates of their prevalence in Europe.Studies published in Europe from January 1, 2000, to September 30, 2012, were identified from searches of four electronic databases. Two independent reviewers appraised the studies and extracted the estimates of interest. Data were pooled using random-effects meta-analyses. Fifty studies were included in a narrative synthesis and 42 studies in the meta-analyses. Although there were significant heterogeneity between the studies, the overall pooled estimates for all age groups of self-reported lifetime prevalence of allergy to cow's milk, egg, wheat, soy, peanut, tree nuts, fish, and shellfish were 6.0% (95% confidence interval: 5.7-6.4), 2.5% (2.3-2.7), 3.6% (3.0-4.2), 0.4% (0.3-0.6), 1.3% (1.2-1.5), 2.2% (1.8-2.5), and 1.3% (0.9-1.7), respectively. The prevalence of food-challenge-defined allergy to cow's milk, egg, wheat, soy, peanut, tree nuts, fish, and shellfish was 0.6% (0.5-0.8), 0.2% (0.2-0.3), 0.1% (0.01-0.2), 0.3% (0.1-0.4), 0.2% (0.2-0.3), 0.5% (0.08-0.8), 0.1% (0.02-0.2), and 0.1% (0.06-0.3), respectively. Allergy to cow's milk and egg was more common among younger children, while allergy to peanut, tree nuts, fish, and shellfish was more common among the older ones. There were insufficient data to compare the estimates of soy and wheat allergy between the age groups. Allergy to most foods, except soy and peanut, appeared to be more common in Northern Europe. In summary, the lifetime self-reported prevalence of allergy to common foods in Europe ranged from 0.1 to 6.0%. The heterogeneity between studies was high, and participation rates varied across studies reaching as low as <20% in some studies. Standardizing the methods of assessment of food allergies and initiating strategies to increase participation will advance this evidence base.

Abstract
Food allergy (FA) prevalence data in infants and preschool-age children are sparse, and proposed risk factors lack confirmation. In this study, 19 children's day care centers (DCC) from 2 main Portuguese cities were selected after stratification and cluster analysis. An ISAAC's (International Study of Asthma and Allergies in Childhood) derived health questionnaire was applied to a sample of children attending DCCs. Outcomes were FA parental report and anaphylaxis. Logistic regression was used to explore potential risk factors for reported FA. From the 2228 distributed questionnaires, 1217 were included in the analysis (54.6%). Children's median age was 3.5 years, and 10.8% were described as ever having had FA. Current FA was reported in 5.7%. Three (0.2%) reports compatible with anaphylaxis were identified. Reported parental history of FA, personal history of atopic dermatitis, and preterm birth increased the odds for reported current FA. A high prevalence of parental-perceived FA in preschool-age children was identified. Risk factor identification may enhance better prevention.

Abstract
Food allergy (FA) is an important atopic disease although its precise burden is unclear. This systematic review aimed to provide recent, up-to-date data on the incidence, prevalence, time trends, and risk and prognostic factors for FA in Europe. We searched four electronic databases, covering studies published from 1 January 2000 to 30 September 2012. Two independent reviewers appraised the studies and qualified the risk of bias using the Critical Appraisal Skills Programme tool. Seventy-five eligible articles (comprising 56 primary studies) were included in a narrative synthesis, and 30 studies in a random-effects meta-analysis. Most of the studies were graded as at moderate risk of bias. The pooled lifetime and point prevalence of self-reported FA were 17.3% (95% CI: 17.0-17.6) and 5.9% (95% CI: 5.7-6.1), respectively. The point prevalence of sensitization to ≥1 food as assessed by specific IgE was 10.1% (95% CI: 9.4-10.8) and skin prick test 2.7% (95% CI: 2.4-3.0), food challenge positivity 0.9% (95% CI: 0.8-1.1). While the incidence of FA appeared stable over time, there was some evidence that the prevalence may be increasing. There were no consistent risk or prognostic factors for the development or resolution of FA identified, but sex, age, country of residence, familial atopic history, and the presence of other allergic diseases seem to be important. Food allergy is a significant clinical problem in Europe. The evidence base in this area would benefit from additional studies using standardized, rigorous methodology; data are particularly required from Eastern and Southern Europe.

Abstract
Background The incidence of food allergy is such that most schools will be attended by at least one food allergic child, obliging school personnel to cope with cases at risk of severe allergic reactions. Schools need to know about food allergy and anaphylaxis management to ensure the personal safety of an increasing number of students. The aim of this study was to investigate Italian school teachers and principals’ knowledge, perceptions and feelings concerning food allergy and anaphylaxis, to deeply understand how to effectively support schools to manage a severely allergic child. In addition a further assessment of the impact of multidisciplinary courses on participants was undertaken. Methods 1184 school teachers and principals attended courses on food allergy and anaphylaxis management at school were questioned before and after their course. Descriptive and inferential statistics were used to analyze the resulting data. Results Participants tended to overestimate the prevalence of food allergy; 79.3% were able to identify the foods most likely involved and 90.8% knew the most frequent symptoms. 81.9% were familiar with the typical symptoms of anaphylaxis but, while the majority (65.4%) knew that “adrenaline” is the best medication for anaphylaxis, only 34.5% knew indications of using adrenaline in children. 48.5% thoroughly understood dietary exclusion. School personnel considered that food allergic students could have social difficulties (10.2%) and/or emotional consequences (37.2%) because of their condition. “Concern” was the emotion that most respondents (66.9%) associated with food allergy. At the end of the course, the number of correct answers to the test increased significantly. Conclusions Having adequately trained and cooperative school personnel is crucial to significantly reduce emergencies and fatal reactions. The results emphasize the need for specific educational interventions and improvements in school health policies to support schools to deal with allergic students ensuring their safety and psychological well-being.

Abstract
Skin prick tests are the first investigation in allergy diagnostics and their use is described in all the guidelines on atopic eczema. However, the clinical usefulness of skin prick tests is the subject of great debate. On the one hand, skin prick tests allow the identification both of individuals at risk for food allergy and of the allergen inducing the eczematous flare. On the other hand, when performed by a non-specific specialist, positive skin prick tests to foods may wrongly lead to prolonged elimination diets, which may induce nutritional deficiencies and perhaps loss of tolerance to the avoided foods. Furthermore, skin prick tests increase health costs. A consensus on this topic has not yet been reached. Considering the diversity of clinical stages in which it occurs, atopic eczema presentation should be the starting point to determine whether or not skin prick tests should be carried out.

Abstract
The exact prevalence of food allergy in the general population is unknown, but almost 12% of pediatric population refers a suspicion of food allergy. IgE mediated reactions to food are actually the best-characterized types of allergy, and they might be particularly harmful especially in children. According to the "hygiene hypothesis" low or no exposure to exogenous antigens in early life may increase the risk of allergic diseases by both delaying the development of the immune tolerance and limiting the Th2/Th1 switch. The critical role of intestinal microbiota in the development of immune tolerance improved recently the interest on probiotics, prebiotics, antioxidants, polyunsaturated fatty acid, folate and vitamins, which seem to have positive effects on the immune functions.Probiotics consist in bacteria or yeast, able to re-colonize and restore microflora symbiosis in intestinal tract. One of the most important characteristics of probiotics is their safety for human health. Thanks to their ability to adhere to intestinal epithelial cells and to modulate and stabilize the composition of gut microflora, probiotics bacteria may play an important role in the regulation of intestinal and systemic immunity. They actually seem capable of restoring the intestinal microbic equilibrium and modulating the activation of immune cells.Several studies have been recently conducted on the role of probiotics in preventing and/or treating allergic disorders, but the results are often quite contradictory, probably because of the heterogeneity of strains, the duration of therapy and the doses administered to patients. Therefore, new studies are needed in order to clarify the functions and the utility of probiotics in food allergies and ion other types of allergic disorders.

Abstract
Exercise-induced anaphylaxis (EIA) is a distinct form of physical allergy. The development of anaphylaxis during exertion often requires the concomitant exposure to triggering factors such as intake of foods (food dependent exercise-induced anaphylaxis) or drugs prior to exercise, extreme environmental conditions. EIA is a rare, but serious disorder, which is often undetected or inadequately treated. This article summarizes current evidences on pathophysiology, diagnosis and management. We reviewed recent advances in factors triggering the release of mediators from mast cells which seems to play a pathogenetic role. A correct diagnosis is essential to avoid unnecessary restricted diet, to allow physical activity in subjects with EIA dependent from triggering factors such as food, and to manage attacks. An algorithm for diagnosing EIA based on medical history, IgE tests and exercise challenge test has been provided. In the long-term management of EIA, there is a need for educating patients and care-givers to avoid exposure to precipitating factors and to recognize and treat episodes. Future researches on existing questions are discussed.
