Patterns of adaptation to children's food allergies

Exploring Food Allergy Management and Food-Related Social Occupations in Elementary School-Aged Children

RATIONALE

Elementary school-aged children with food allergies face barriers to navigating safe food practices in concert with socializing while eating. Little research examines children's role in managing their health (i.e., a food allergy).

OBJECTIVES

This qualitative descriptive study explores the experiences of preadolescent children with food allergies relating to food allergy management and socialization in various foodscapes in the United States.

METHOD

Data gathering strategies included interviews, diaries, and photo elicitation. The analysis involved coding, discussion, and thematic development.

FINDINGS

Participants shared food allergy management with caregivers depending on the environment. They learned to educate others, respond to emergencies, and prepare daily relating to food allergies. They faced conflict with managing food allergies with peers but overall perceived food allergy management as a low burden.

CONCLUSION

When provided with positive social and environmental supports, school-aged children with food allergies can learn to safely manage social food environments without direct parental involvement.

The Lived Experiences of Students With Food Allergies During a Usual Weekday

BACKGROUND

Extant literature indicates students living with food allergies (FA) experience biopsychosocial challenges (eg, social isolation, anxiety). The purpose of this study was to explore the experiences of students living with FA during a usual weekday in a school setting.

METHODS

Phenomenological study with purposive convenience sample from the US states of Florida and Colorado. Students aged 10-14 years who have been managing an IgE-mediated FA for more than 1 year within a school setting. Data collection was guided by a story path process with semi-structured interview, with Interpretive Phenomenological Analysis used to ascribe meaning to their experiences.

RESULTS

Four themes: (1) Living with Restraints: A Way of Life, (2) Managing Exposure, (3) Experiencing Stigma, and (4) Experiencing Lack of Knowledge.

CONCLUSION

Findings underscore unique biopsychosocial challenges faced by students living with FA, highlighting the need for comprehensive approaches beyond traditional biological management in developing strategies, policies, future research, and recommendations in school settings.

Systematic Review of the Incidence and/or Prevalence of Eating Disorders in Individuals With Food Allergies

BACKGROUND

Chronic diseases involving strict dietary adherence have been associated with an increased risk of eating disorders (EDs). This is the first systematic review investigating the rate of EDs among individuals with food allergies (FAs).

OBJECTIVE

To report the incidence, prevalence, and types of EDs in individuals with FAs.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched 4 databases for studies published to January 2022 that reported the prevalence or incidence of EDs in samples with immunoglobulin E (IgE) or non-IgE-mediated allergy. Risk of bias was assessed and evidence qualitatively synthesized.

RESULTS

From 1,180 papers identified, 9 met inclusion criteria. There were 4,161 adult and pediatric participants with IgE-mediated FAs or eosinophilic esophagitis. Avoidant/Restrictive Food Intake Disorder (ARFID) or anorexia nervosa/bulimia nervosa were the main EDs identified. The prevalence of EDs in samples with FA ranged from 0.8% to 62.9%. Among studies investigating IgE-mediated FA (n = 6), the prevalence of anorexia nervosa and/or bulimia nervosa ranged from 17.6 to 61%, ARFID was 62.9%, and unspecified EDs was 0.8% to 6%. Among samples with eosinophilic esophagitis (n = 3), ARFID prevalence ranged from 4.5% to 51%. Most studies were limited by small sample size, possible selection bias, and lack of diagnostic EDs tools validated for food allergic populations.

CONCLUSIONS

Eating disorders appear prevalent in individuals with FA; however, prevalence estimates varied widely. Large studies with healthy control groups and validated measures to identify EDs in individuals with FA are needed to accurately determine the prevalence of EDs.

Cognitive-behavioral intervention for anxiety associated with food allergy in a clinical sample of children: Feasibility, acceptability, and proof-of-concept in children

BACKGROUND

Multiple reviews have identified a lack of evidence-based treatments for excessive anxiety in the context of food allergy (FAA) as an unmet need.

OBJECTIVE

To evaluate the feasibility, acceptability, and proof of concept of Food Allergy Bravery (FAB), a brief, novel, manualized cognitive-behavioral-based intervention for anxiety in a clinical sample of children with FAA.

METHODS

A total of 3 cohorts of children (aged 8 to 12 years) with clinically impairing FAA and their parents were offered a course of FAB delivered in a group format. Ratings of anxiety severity and quality of life were collected at pretreatment, posttreatment, and 2- to 4-month follow-up.

RESULTS

All families offered treatment completed the full course of FAB, attended at least 5 of 6 active treatment sessions, and rated the intervention as highly satisfactory. All children were rated as very much improved or much improved on the Clinician Global Impression scale at posttreatment. Anxiety severity scores on the Scale of Food Allergy Anxiety and the Scale of Child Anxiety-Related Emotional Disorders significantly declined per both child and parent reports. Scores on the Food Allergy Quality of Life Questionnaire-Parent Form were significantly improved. Gains were maintained at follow-up.

CONCLUSION

This is the first study of an outpatient manualized psychosocial treatment for FAA in a clinically ascertained sample of children. Findings provide initial evidence of feasibility, acceptability, and proof of concept for the FAB intervention protocol. Randomized controlled trials are needed.

Children at risk of anaphylaxis: A mixed-studies systematic review of parents' experiences and information needs

Objective

To explore parents' self-reported experiences and information needs regarding recognition and management of pediatric anaphylaxis.

Methods

We searched Ovid Medline, Ovid PsychInfo, CINAHL Plus, the Cochrane Library, and grey literature to identify primary studies in English or French published since 2000. We used a mixed-method appraisal tool and convergent integrated approach to assess quality and synthesize data, respectively.

Results

43 studies were included (22 quantitative, 19 qualitative, and 2 mixed-method); 77% of studies had high methodological quality. Parents' experiences were categorized as: recognizing an anaphylactic reaction; managing and responding to a reaction; emotional impact of caring for a child at risk of anaphylaxis; and interaction with the health system and healthcare providers. Parents' information needs were categorized into themes relating to: gaps in knowledge and information; type of information desired; information sources; and information delivery format.

Conclusion

Negative emotional experiences and a general lack of information were commonly reported by parents of included studies. Provision of relevant and comprehensible information may help parents to make informed decisions and manage reactions promptly.

Innovation

The findings of this review are guiding the development of an innovative knowledge translation tool (KT) as part of a larger initiative of developing a suite of parent-focused KT tools for acute childhood conditions.

The Development of Age-Based Food Allergy Educational Handouts for Caregivers and Patients: A Work Group Report of the AAAAI Adverse Reactions to Foods Committee

BACKGROUND

Food allergy education is an ongoing process that must address unique safety concerns and psychosocial challenges at each developmental stage. Families require reliable information that is targeted to specific developmental stages to support the integration of food allergy management into daily life.

OBJECTIVE

The purpose of this project was to develop age-specific, evidence-based patient education handouts with practical recommendations for managing and coping with food allergies at different developmental stages.

METHODS

Handout content was based on: (1) practice guidelines for food allergy management; (2) literature addressing psychosocial and educational needs of patients with food allergy and their caregivers; and (3) clinical experience of the project team. Fifty-seven caregivers of patients (aged 0-21 years) with food allergy and 2 young adults with food allergy reviewed a draft of the handouts and completed an online survey to assess handout acceptability and usability and identify areas for improvement. Handouts were revised based on participant feedback.

RESULTS

The majority of participants (79%) rated the amount of information in the age-specific handouts as "just right," versus "not enough" (9%) or "too much" information (12%). Sixty-three percent reported that they would be "very likely" to use the handouts as a resource and 35% "somewhat likely." Almost all participants (88%-100% by item) agreed that the handouts used elements of plain language writing and clear communication.

CONCLUSION

Caregivers rated the age-based food allergy education handouts as understandable and useful. We anticipate that these handouts could be used during health care visits and directly accessed online by families.

Egg Reintroduction Following Oral Food Challenge in Japanese Children

Background: Oral food challenge (OFC) is the most reliable method for diagnosing food allergies. However, the scarcity of long-term data on eating habits of people after a negative OFC poses a challenge for provisional medical care.

Objective: This study was performed to investigate the percentage of people who could reintroduce eggs into their diet several years after an OFC.

Methods: Study participants included 0–6-year-old children with negative results from an OFC using one egg as the food allergen, boiled for 20 min, from January 2012–March 2017, 1–3 years after the OFC.

Results: A total of 72 subjects were analyzed, out of which 52 were males (72.2%). The median age (range) was 20 months (16–32.3), and the median age (range) at the first OFC was 15 months (12.8–23.3). Eggs were reintroduced in 62 cases (86.1%), while 10 cases (13.9%) did not undergo any diet change. The adjusted odds ratio (OR, 95% CI), with post-OFC to pre-OFC anxiety ≥ 0.2, was 9.4 (1.0–86), p = 0.04; OR for allergic symptoms that occurred post-OFC was 2.2 (0.45–11), p = 0.34; OR for initial OFC at an age of ≥15 months was 3.2 (0.54–19), p = 0.2; and OR for the history of anaphylaxis from eggs was 0.17 (0.02–1.5), p = 0.11.

Conclusion: Most cases reintroduced eggs after an OFC. However, reintroduction did not occur in some cases, which was associated with greater anxiety among caregivers post-OFC. If the caregiver's anxiety is intense, it is necessary to provide psychological intervention and dietary guidance when reintroducing eggs at home after an OFC and to follow-up outpatient long-term progress.

The relationship between dietary elimination and maternal psychopathology in breastfeeding mothers of infants with food allergy

BACKGROUND

There has been no study evaluating the psychopathology in breastfeeding mothers of infants with food allergy (FA).

OBJECTIVE

The aim of the study was to investigate the relationship between dietary elimination and maternal psychopathology, specifically anxiety, depression, and mother-to-infant bonding, in breastfeeding mothers of infants with food allergy.

METHODS

Breastfeeding mothers following an elimination diet due to FA in their children aged 1-to-12 months were compared with the healthy controls. The physician-diagnosed FA group was divided into IgE-, non-IgE-mediated, and infants with some minor symptoms which were not enough to make the diagnosis of FA were classified as Indecisive symptoms for FA group. Mothers completed standardized questionnaires including Symptom Checklist 90R, Beck Depression/Anxiety Inventories (BDI/BAI), Postpartum Bonding Questionnaire (Bonding).

RESULTS

Of 179 mother and infants, 64 were healthy, 89 were FA, 16 were indecisive symptoms for FA. The mean age of the mothers and infants were 31.1 ± 4.7 years and 6.3 ± 3.6 months, respectively. The physician-diagnosed FA groups had higher scores for anxiety (p = .008), anger (p = .042), depression (p < .001), obsession (p = .002), phobia (p = .008), somatization (p = .002), general symptom index (GSI) (p = .001), BDI (p < .001), BAI (p = .008), and Bonding (attachment [p = .001], anger [p = .019], and total [p = .036]) than the healthy ones. The indecisive symptoms for FA group had a similar score pattern to physician-diagnosed FA, except interpersonal sensitivity, BDI, and attachment.

CONCLUSION

Breastfeeding mothers of infants with FA were more anxious, with higher depression scores than controls, and had many psychopathologies which affected bonding. Interventions targeting negativity in caregivers' social relationships are urgently needed.

Food-allergy-specific anxiety and distress in parents of children with food allergy: A systematic review

BACKGROUND

Parenting a child with food allergy (FA) can lead to impaired quality of life and family functioning. Anxiety is a critical component of FA-associated distress and a potential target for therapeutic intervention. This systematic review aimed to clarify the concept of FA-specific anxiety (FAA) and its antecedents, consequences, and correlates and to determine the extent to which existing FA-specific outcome measures capture symptoms of parental distress and FAA.

METHODS

MEDLINE, EMBASE, PsycINFO, and CENTRAL were searched for qualitative and quantitative studies examining distress or anxiety in parents of children with FA through August 2020. This review was registered with PROSPERO (CRD42020208316) and conducted in accordance with PRISMA guidelines.

RESULTS

Ninety-eight studies were included in the final narrative synthesis. Most participants were mothers, and reporting of demographic data was limited. Parents identified anxiety as the most burdensome form of FA-specific emotional distress. Several allergy-related factors as well as medical and psychosocial interventions were associated with reduced parental anxiety and distress. However, affective, cognitive, and behavioral dimensions of FAA were only partially addressed by existing measures for general anxiety symptoms and FA-specific parental factors.

CONCLUSIONS

FAA contributes to distress and functional impairment among parents of children with FA. Current FA-specific parent measures fail to adequately capture dimensions of FAA, suggesting that further work is needed to improve the assessment and monitoring of FAA and its impacts. Characterization of this construct represents an initial step in developing standardized methods for assessing and monitoring FAA in clinical populations.

White paper on peanut allergy - part 1: Epidemiology, burden of disease, health economic aspects

Peanuts are Leguminosae, commonly known as the legume or pea family, and peanut allergy is among the most common food allergies and the most common cause of fatal food reactions and anaphylaxis.

The prevalence of peanut allergy increased 3.5-fold over the past two decades reaching 1.4–2% in Europe and the United States. The reasons for this increase in prevalence are likely multifaceted. Sensitization via the skin appears to be associated with the development of peanut allergy and atopic eczema in infancy is associated with a high risk of developing peanut allergy.

Until recently, the only possible management strategy for peanut allergy was strict allergen avoidance and emergency treatment including adrenaline auto-injector in cases of accidental exposure and reaction.

This paper discusses the various factors that impact the risks of peanut allergy and the burden of self-management on peanut-allergic children and their caregivers.

Development of the Child- and Parent-Rated Scales of Food Allergy Anxiety (SOFAA)

BACKGROUND

Anxiety can be excessive and impairing in children with food allergy (FA). There is no accepted condition-specific measure of anxiety for this population.

OBJECTIVE

To evaluate the validity and reliability of new child- and parent-rated measures of FA-related anxiety in youth.

METHODS

Items for the Scale of Food Allergy Anxiety (SOFAA) were developed by a cognitive-behavioral therapist specializing in pediatric anxiety, in consultation with FA medical professionals and parents of children with FA. Dyads (n = 77) of children with FA (aged 8-18 years; 42.9% females) and their parents (95.5% females) completed full versions of the SOFAA (21 items; scored 0-4) via online survey.

RESULTS

The child-rated SOFFA-C mean score was 29.1 ± 18.3; the parent-rated SOFAA-P mean score was 33.9 ± 16.1. Higher scores indicate higher reported anxiety. Coefficient alphas were 0.94 and 0.92. Factor analyses and item-response theory analyses supported the creation of the 14-item SOFAA-C-brief and the 7-item SOFAA-P-brief, accounting for 93% and 79% of total variance, respectively. Correlations revealed strong convergence between child- and parent-report for both the full (r = 0.85) and brief (r = 0.79) versions. Correlations with a generic measure of child anxiety (Screen for Child Anxiety Related Disorders) and the Food Allergy Quality of Life Questionnaire ranged from moderate to strong, whereas those with a generic measure of child eating problems (About Your Child's Eating) were weak to moderate, supporting convergent and divergent validity. Scores of 48 dyads who completed SOFAAs at time 2 (mean, 16.0 days) appeared stable over time, supporting test-retest reliability.

CONCLUSIONS

The 21-item SOFAA-C and SOFAA-P are reliable and valid scales for measuring condition-specific anxiety in youth with FA. As shorter screening measures, the SOFAA-C-brief and the SOFAA-P-brief are also reliable and valid.

The global burden of illness of peanut allergy: A comprehensive literature review

Peanut allergy (PA) currently affects approximately 2% of the general population of Western nations and may be increasing in prevalence. Patients with PA and their families/caregivers bear a considerable burden of self‐management to avoid accidental peanut exposure and to administer emergency medication (adrenaline) if needed. Compared with other food allergies, PA is associated with higher rates of accidental exposure, severe reactions and potentially fatal anaphylaxis. Approximately 7%–14% of patients with PA experience accidental peanut exposure annually, and one‐third to one‐half may experience anaphylaxis, although fatalities are rare. These risks impose considerably high healthcare utilization and economic costs for patients with PA and restrictions on daily activities. Measures to accommodate patients with PA are often inadequate, with inconsistent standards for food labelling and inadequate safety policies in public establishments such as restaurants and schools. Children with PA are often bullied, resulting in sadness, humiliation and anxiety. These factors cumulatively contribute to significantly reduced health‐related quality of life for patients with PA and families/caregivers. Such factors also provide essential context for risk/benefit assessments of new PA therapies. This narrative review comprehensively assessed the various factors comprising the burden of PA.

The Unmet Needs of Patients with Food Allergies

This article reviews the unmet needs of patients with food allergies. Anxiety is common among patients with food allergies and their caregivers, which naturally stems from the avoidance, exposure, and uncertainty involved in care. Anxiety associated with allergen avoidance can have both adaptive and detrimental effects on overall health. Anxiety has implications for transitioning the responsibility of health and well-being from caregivers to the patients. As more children with food allergies become adults with food allergies, this will be an urgent topic. Moreover, as more exposure-based therapies become available, understanding patients' psychological expectations and experiences of exposure is vital.

Food Allergy Symptom Self-Management With Technology (FASST) mHealth Intervention to Address Psychosocial Outcomes in Caregivers of Children With Newly Diagnosed Food Allergy: Protocol for a Pilot Randomized Controlled Trial

Background

Approximately 2.4 million children in the United States suffer from food-induced anaphylaxis, a condition that is annually responsible for over 200 deaths and 200,000 emergency room visits. As a result, caregivers of children newly diagnosed with severe and life-threatening food allergic reactions experience clinically significant symptoms of psychological distress, including fatigue, anxiety, depressed mood, social isolation, and substantially reduced quality of life. Despite this recognition, there is a lack of caregiver-centered self-management interventions to address these concerns.

Objective

In this protocol, we propose to develop and conduct feasibility testing of a technology-enhanced, self-management, mobile health, smartphone app intervention called Food Allergy Symptom Self-Management with Technology for Caregivers (FASST) designed to meet the psychosocial health needs of caregivers of children with a new diagnosis of food allergy.

Methods

This pilot study uses qualitative work (Phase I) to inform a 4-week longitudinal randomized controlled trial (Phase II). In Phase I, 10 caregivers of children (≤18 years old) with established food allergy (≥1 year from diagnosis) will participate in semistructured interviews to inform the development of the FASST app. In Phase II, 30 caregivers of children (≤18 years old) with a newly diagnosed food allergy (≤90 days from diagnosis) will be randomized 2:1 to receive the FASST intervention (n=20) or control condition (basic app with educational resources; n=10). Process measures include feasibility, caregiver acceptability, adherence, and satisfaction. Outcome measures include caregiver fatigue, anxiety, depression, sleep, self-efficacy, and quality of life measured at baseline, week 4, and 3 months post study completion.

Results

Phase I study activities have been completed, and Phase II participant enrollment into the randomized controlled trial is expected to commence in 2021.

Conclusions

With limited readily available resources at their disposal, the results from this study have the potential to provide caregivers of children with a newly diagnosed food allergy a tool to help them self-manage and mitigate negative psychosocial factors during a critical time period in the caregiving/condition trajectory.

Allergy to Peanuts imPacting Emotions And Life (APPEAL): the impact of peanut allergy on children, adolescents, adults and caregivers in France

Background

Peanut allergy (PA) has increased in developed countries and can have a dramatic effect on quality of life but data surrounding this is limited in France. Allergy to Peanuts imPacting Emotions And Life study (APPEAL) investigated the experience and impact of living with PA in France.

Methods

Respondents affected by PA directly (children aged 8–12 years, teenagers aged 13–17 years, or adults aged ≥ 18 years) or indirectly (caregiver) completed either an online questionnaire (APPEAL-1, N = 198), or provided in-depth interviews (APPEAL-2, N = 32). Quantitative data was evaluated using descriptive statistics. Qualitative data was analysed thematically, using MAXQDA software.

Results

Of 198 responders in APPEAL-1, 88% stated that PA affects their daily activities, and 74% felt isolated as a result of living with PA. Feelings of worry about exposure to peanuts on social occasions where food is involved was reported by 91%. A total of 44% reported some restrictions in their job options, 85% in socializing. Psychological impact of PA included responders feeling emotions of frustration (89%), uncertainty (87%), and stress (93%) and 93% reporting encountering instances of feeling different due to their PA. Main factors that drove PA impact included social activities and relationships; whereas main coping strategies to avoid peanuts included monitoring, communication and planning.

Conclusion

The analysis of French respondents from the APPEAL study demonstrates the impact and burden of PA on allergic children, teenagers, adults and their caregivers, and highlights the unmet need to be addressed.

Parent perceptions in managing children with food allergy: An Australian perspective

INTRODUCTION

Food allergy affects up to 10% of Australian children, and living with food allergic children can be challenging for parents. This study explored parental perceptions and knowledge as they navigate a new reality of keeping their child safe.

METHODS

Parents of children with food allergies completed an online food allergy survey in 2015. Questions explored health knowledge, skills, and attitudes (KSAs) as well as quality of life (QoL) through the inclusion of the Food Allergy Quality of Life - Parental Burden instrument (FAQL-PB). Notification of the survey included advertisements to more than 700 randomly selected Australia-wide preschools, 44 allergy specialists, and Allergy & Anaphylaxis Australia. Responses were tabulated and analysed.

RESULTS

Of the 400 participants who logged on, 357 commenced the survey and 318 finished. Questionnaire analysis showed that 44.1% of parents (n = 135) hesitated to use an adrenaline auto-injector and may be influenced by a classification system where symptom severity is not universally understood. While 79% would sign up to a national Anaphylaxis Registry, intention to participate in clinical trials using vaccines was disclosed by only 56%. Allergen labelling and community acceptance continue to be the most challenging aspects of managing a food allergy, and 50% of parents reported that food allergy played a role in choosing a preschool or primary school. Overall, quality of life for participants was influenced more by gender (male) and age of the child than where they lived - capital city or regional location; however, regional participants were more frustrated over lack of appreciation relating to the seriousness of food allergy (p = 0.010).

CONCLUSION

Results highlight the need for educational strategies for both the food allergy community and public, particularly in regional areas, since there is a perceived lack of appreciation as to the seriousness of food allergy. Educational resources and relevant networks are required to support parents and caregivers in the management of children with food allergy.

Examining Differences in Parent Knowledge About Pediatric Food Allergies

Objective

Pediatric food allergy (FA) is a serious health condition that has become increasingly prevalent. Parents often play a primary role in assessing and managing risk for their child’s FAs, making it critical that they remain informed of the most recent guidelines for FA management. This study aimed to examine if diagnostic source (i.e., pediatrician vs. allergist) and child- and parent-level variables predicted parental FA knowledge using a comprehensive measure.

Methods

The Food Allergy Knowledge Test (FAKT) was administered to parents (N = 518) of children aged 3–17 years with (n = 349) and without (n = 169; i.e., control group) FAs using internet-sampling procedures. The sample was further partitioned into parents of children diagnosed by an allergist or a pediatrician, and control group parents who did or did not endorse knowing someone with an FA.

Results

Significant group differences were found with respect to the overall FAKT score and diagnostic source. Among the FA group, parental relationship to child, income, identification with a minority status, parental anxiety, and child possession of an emergency action plan were significant predictors of FAKT scores.

Conclusions

Knowledge of FA was poor across all groups. Education for caregivers both with and without food-allergic children is important to ensure FA safety in multiple settings. Future directions and limitations are discussed.

Therapy competence in delivering a brief cognitive behavioural therapy intervention to reduce maternal anxiety associated with child food allergy

Child food allergy is increasingly prevalent, and caring for such children is associated with elevated parental anxiety. We previously carried out a randomized-controlled trial (RCT) of brief cognitive behavioural therapy (CBT) for parental anxiety associated with child food allergy which found that treatment to be effective. This study describes the manualized brief CBT intervention and assesses the acquisition of competence in delivering this therapy. Three healthcare professionals were trained and supervised in the delivery of brief CBT to 98 mothers of food-allergic children. Competency was assessed using the Revised Cognitive Therapy Scale (CTS-R), with 'competency' defined as a CTS-R score ≥3. All therapists' CTS-R scores increased over time. In the first four months, the mean (SD) CTS-R score was 2.31 (0.56), increasing to 3.14 (0.41) in the second four months (p < .001). Overall, 13/19 (68%) of CBT sessions were rated with a CTS-R score ≥3 in the second four months. After eight months, all therapists were performing CBT at a competent level (17 of the 18 sessions or 94%). The therapists participated in a RCT that reduced maternal anxiety (reported elsewhere). We have shown that therapists not previously trained in CBT can be trained in specific interventions and reach competent levels quickly.

Allergen immunotherapy for IgE-mediated food allergy: There is a measure in everything to a proper proportion of therapy

IgE-mediated food allergy (FA) is a potentially life-threatening condition with a negative impact on quality of life and an increasing prevalence in westernized countries in the recent two decades. A strict avoidance of the triggering food(s) represents the current standard approach. However, an elimination diet may be difficult and frustrating, in particular for common foods, (eg, milk, egg, and peanut). Food allergy immunotherapy (FA-AIT) may provide an active treatment that enables to increase the amount of food that the patient can intake without reaction during treatment (ie, desensitization), and reduces the risk of potential life-threatening allergic reaction in the event of accidental ingestion. However, several gaps need still to be filled. A memorable Latin orator stated: "Est modus in rebus" (Horace, Sermones I, 1, 106-07). This sentence remembers that there is a measure in everything to a proper proportion of therapy. The common sense of measure should find application in each stage of treatment. A personalized approaching should consider the specific willing and features of each patient. Efforts are devoted to improve the efficacy, the safety but also the quality of life of patients suffering from FA. In the near future, it will be important to clarify immunologic pathways of FA-AIT, and to identify reliable biomarkers in order to recognize the most suitable candidates to FA-AIT and algorithms for treatments tailored on well-characterized subpopulations of patients.

Food allergy in EAACI journals (2016)

Over the last years we have observed considerable progress in the area of food allergy, particularly in children. This review article focusses on important contributions which have lately been published in the three journals of the European Academy of Allergy and Clinical Immunology. A better understanding of allergens as well as the mechanisms of sensitization and tolerance induction may hopefully lead to a more targeted management of food allergy in the near future.

An update on the impact of food allergy on anxiety and quality of life

PURPOSE OF REVIEW

Food allergies have become more common, and management involves dietary avoidance that can impair quality of life. Patients and families must manage the daily risk of anaphylaxis at each meal. The purpose of this review is to describe the impact of food allergies on quality of life and to provide an update on new developments in food allergy management, particularly peanut allergy.

RECENT FINDINGS

Food allergy requires careful avoidance of common and ubiquitous dietary allergens. Living with food allergy is associated with annual economic costs in excess of $4000 per child, in addition to risks of anxiety and depressive symptoms. An expert panel sponsored by the 2017 National Institute of Allergy and Infectious Diseases published addendum guidelines for the prevention of peanut allergy, which suggest three separate approaches to peanut protein introduction for infants at various levels of risk.

SUMMARY

Clinicians must be aware of underappreciated burdens faced by children and families with food allergies. Management involves a partnership between primary and specialty care. Mitigation strategies to improve quality of life for patients include efforts to avoid overdiagnosis in synergy with balanced counseling about the risks of food allergies. Experimental food allergen desensitization can improve quality of life but remains investigational at this time. For patients with significant anxiety, interdisciplinary management involving professional counseling may be helpful. Risk stratification and early introduction of peanut protein can help prevent the development of peanut allergy.

Food Allergy and Anxiety and Depression among Ethnic Minority Children and Their Caregivers

OBJECTIVE

To investigate the relationship between food allergy and symptoms of anxiety and depression among ethnic minority, low socioeconomic status (SES) children and their caregivers.

STUDY DESIGN

Pediatric patients ages 4-12 years with and without food allergy and their caregivers were recruited from urban pediatric outpatient clinics. Statistical analyses were used to examine the prevalence of symptoms of anxiety and depression among patients and their caregivers with and without food allergy, adjusting for asthma.

RESULTS

Eighty patients ranging from ages 4 to 12 years, with a mean age of 8.1 years, and their caregivers participated in the study. Food allergy was associated with significantly higher t scores on the Multidimensional Anxiety Scale for Children (MASC) Total (P = .007), MASC Humiliation Rejection, (P = .02) and MASC Social Anxiety (P = .02) among pediatric patients, adjusting for asthma. Food allergy was not associated with child depression symptoms, nor was there a significant difference in anxiety or depression symptoms among caregivers of patients with and without food allergy.

CONCLUSIONS

Food allergy appears to be associated with increased symptoms of social anxiety and higher levels of anxiety overall, but not depression, in ethnic minority children of lower socioeconomic status. This finding was not due to confounding by asthma. Food allergy was not associated with higher levels of depression or anxiety symptoms among caregivers of pediatric patients with food allergy. Future studies should investigate potential pathways between food allergy and anxiety that may be unique to children in underserved populations, and develop interventions to reduce anxiety in children with food allergy.

Examining Profiles of Family Functioning in Pediatric Asthma: Longitudinal Associations With Child Adjustment and Asthma Severity

Objective

Identify profiles of functioning in families of children with asthma and examine whether profile membership predicts subsequent child mental and physical well-being.

Methods

Primary caregivers and children ( N  = 1,030) from the Childhood Asthma Management Program completed questionnaires assessing family functioning and child adaptation at five time points. Asthma severity was also assessed via spirometry.

Results

Latent profile analyses identified a four-profile solution as best fitting the data: cohesive, permissive, controlling/disengaged, and controlling/enmeshed families. Distal outcome analyses using Bolck-Croon-Hagenaars techniques suggested that children from families that were more cohesive had fewer internalizing and externalizing symptoms. These associations remained stable across time. Family profiles did not differ with regards to child asthma severity.

Conclusion

Results highlight the importance of looking beyond the effects of distinct components of family functioning and instead using pattern-based approaches. Recommendations for incorporating screenings and services for families in pediatric care settings are provided.

The Emperor Has No Symptoms: The Risks of a Blanket Approach to Using Epinephrine Autoinjectors for All Allergic Reactions

Fatal anaphylaxis in humans is rare and unpredictable. We note a trend to provide allergic individuals with care plans that recommend immediate use of epinephrine autoinjectors if allergen ingestion is suspected, even in the absence of any allergic symptoms, without any supporting evidence base. Instructions to use an autoinjector device, irrespective of reaction severity and especially when symptoms are actually absent, are likely to add to parental and patient anxiety. Of greater concern is the possibility of epinephrine being administered “too early” to treat initial, mild symptoms that then progress to severe anaphylaxis. It is not hard to visualize a scenario where one or both epinephrine autoinjectors have been deployed for mild symptoms, yet the reaction progresses to a severe reaction and no further epinephrine is available for administration. Epinephrine needs to be available as a rescue treatment for anaphylaxis, potentially buying valuable minutes while emergency medical services are activated to attend. Food-allergic individuals and their carers need to be provided with more constructive strategies and support than merely being told to “use your pen.”

Degree of anxiety in food allergic children in a tertiary care center

BACKGROUND

The link between internalizing psychiatric disorders, such as anxiety and depression, and allergic diseases has attracted a high level of interest from psychiatrists and immunologists. Recent studies have found increased anxiety in children with asthma, but findings in children with food allergy (FA) have been inconsistent.

OBJECTIVE

It was hypothesized that children with FA would score significantly higher on a standardized anxiety screen than general pediatric (GP) patients but not as high as patients with diagnosed anxiety disorders.

METHODS

A total of 114 patients aged 8 to 16 years (37 with confirmed anxiety disorder from a pediatric psychiatry clinic, 40 with confirmed FA from a pediatric allergy clinic, and 43 well-care patients from a GP clinic) and their mothers completed the Screen for Child Anxiety Related Emotional Disorders (SCARED).

RESULTS

Children and mothers in the allergy group did not report increased levels of anxiety in children on total SCARED scores or subscales compared with children and mothers from the GP group. There was a trend toward increased panic disorder symptoms reported in children by mothers of children in the allergy group, but this finding did not reach statistical significance.

CONCLUSION

Children with FA did not have increased anxiety; however, there was a trend for mothers of children with allergies to report more symptoms of panic disorder in their children. It remains important to screen families for anxiety-related symptoms and refer them to mental health services when indicated.
