Abstract
Food allergies (FA) pose risks beyond just the physical harm caused by anaphylaxis. The psychological consequences associated with an FA diagnosis can arguably be more detrimental for long-term health and quality of life than the consequences of an actual reaction. This can be seen in the hypervigilance of patients and caregivers surrounding mealtime, limited social interactions with peers, strained familial relationships, and increased reluctance to travel.1 More than 40% of children with FA have experienced at least one severe food-induced reaction. Given the need for daily nourishment, the potential for a very small amount leading to a life-threatening reaction is real, so it is not surprising that fear and anxiety can overwhelm patients with this condition.1 , 2 Allergists have a responsibility to recognize the difference between adaptive versus maladaptive anxiety. Whereas the demands of a busy office can often dissuade prolonged in-depth conversations about mental health, there are several validated tools that can be used to quickly and efficiently identify patients at risk. Allergists can play an important role in how an FA diagnosis is conceptualized and whether families leave the office with confidence or with excessive amounts of fear. Instilling a healthy respect for foods without crippling families with anxiety should be the goal of any clinic visit. To provide optimal support and treatment for patients with increased stress and anxiety, there needs to be a more substantial and easily accessible network of mental health professionals integrated within FA treatment centers so that patients and their families have the resources to address their mental health needs.

Rahman S, Elliott SA, Scott SD, Hartling L. Children at risk of anaphylaxis: A mixed-studies systematic review of parents' experiences and information needs. PEC INNOVATION 2022; 1:100018. [PMID: 37213745 PMCID: PMC10194313 DOI: 10.1016/j.pecinn.2022.100018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 01/13/2022] [Accepted: 01/17/2022] [Indexed: 05/23/2023]
Abstract
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.

Pediatr Allergy Immunol 2022; 33:e13695. [PMID: 34779046 DOI: 10.1111/pai.13695] [Citation(s) in RCA: 27] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 10/05/2021] [Accepted: 10/28/2021] [Indexed: 12/21/2022]
Abstract
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.

Abstract
Oral food challenges are an integral part of an allergist's practice and are used to evaluate the presence or absence of allergic reactivity to foods. A work group within the Adverse Reactions to Foods Committee of the American Academy of Allergy, Asthma & Immunology was formed to update a previously published oral food challenge report. The intention of this document was to supplement the previous publication with additional focus on safety, treatment of IgE-mediated allergic reactions, guidance for challenges in infants and adults, psychosocial considerations for children and families participating in an oral food challenge, specific guidance for baked milk or baked egg challenges, masking agents and validated blinding recipes for common food allergens, and recommendations for conducting and interpreting challenges in patients with suspected food protein-induced enterocolitis syndrome. Tables and figures within the report and an extensive online appendix detail age-specific portion sizes, appropriate timing for antihistamine discontinuation, serum and skin test result interpretation, written consents, and instructional handouts that may be used in clinical practice.

Abstract
PURPOSE Food allergy management places a daily psychosocial burden on patients and their caregivers. New food allergy treatments may positively impact their lives, but also introduce new stressors. The purpose of this paper is to provide an overview of the current state of the literature regarding patients' and caregivers' food allergy experiences and needs within the United States as well as a set of recommendations regarding how best to proceed with patient-centered development and evaluation of new food allergy treatments. RECENT FINDINGS The first pharmaceutical-grade product for peanut oral immunotherapy was approved in the United States for children aged 4-17 years following a successful international Phase 3 trial. This new treatment is only the first of several food allergy treatments currently under development. Patients will soon be presented with multiple options for food allergy treatment and will need to make decisions about what treatment is best for them. SUMMARY Allergy researchers and providers are encouraged to consider patients' perspectives and needs when developing and evaluating new food allergy treatments. Recommendations regarding next steps include the development of new patient-reported outcome tools, focus on psychosocial support, health disparities, and financial implications, and research harmonization and interdisciplinary collaboration.

Abstract
BACKGROUND In the context of food allergy, excessive parental anxiety can be maladaptive and lead to unnecessary restriction of social activities. No validated tool exists to measure food allergy-associated anxiety (FAAA). This study sought to explore factors associated with parental FAAA, determine sensitivity and specificity of using generic state anxiety measure-State-Trait Anxiety Inventory (STAI) versus FAAA, and determine whether validated tools for generalized anxiety or food allergy-specific quality of life (QoL) could be used as surrogates for FAAA. METHODS Canadian parents of food-allergic children completed an online survey. Without a validated tool for FAAA, a visual analogue scale was used to assess parent-reported FAAA. Multivariable linear regression was performed with FAAA as the outcome. Sensitivity and specificity analysis of state anxiety vs. FAAA, and factor analysis of state anxiety and QOL, was performed to determine whether these could be used as surrogates for FAAA. RESULTS A total of 548 of 1244 parents (44.1%) completed the survey. Factors positively associated with FAAA included parental burden, risk perception, state anxiety, intolerance of uncertainty and perceived severity of child's food allergy; personal/family history of mental health was negatively associated. Sensitivity and specificity of state anxiety were 68.6% and 70.0%. Factor analysis revealed that state anxiety and QOL were correlated (r = 0.54, P < .001) but distinct constructs. CONCLUSION Our study identified factors associated with FAAA, and determined that generic anxiety and QOL tools do not accurately categorize parents with self-reported high FAAA. Future research will develop a validated screening tool to help allergists identify anxious parents and provide psychosocial resources.

Abstract
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.

Abstract
BACKGROUND Many children with cow's milk allergy (CMA) develop tolerance, but, challenges in daily life may remain. Using the Food hypersensitivity famiLy ImPact questionnaire (FLIP), we sought to monitor changes in the impact of CMA over time. METHODS Families of children with CMA, who participated in the validation of the FLIP, were re-approached 6 months later for follow-up. Change in reported difficulties was assessed by paired sample t-test and mixed models, stratifying by outgrown vs. persistent CMA. RESULTS Impact on families with children who had outgrown CMA (n = 20) decreased in the FLIP's total score (p = 0.0001) and in two subscales; Health and Emotions (p = 0.0001) and Everyday Life (p = 0.0001). In contrast, no significant improvements were registered in nutritional concerns. Impact on the group with persistent CMA (n = 57) was unchanged at follow-up except for more impact on Everyday Life (p = 0.001). In the final analysis comparing longitudinal changes in the groups, the strongest differences were observed for the subscales Health & Emotions and Everyday Life; for the Nutrition subscale, the between-group changes also differed, but to lesser extent. CONCLUSIONS We have documented the varying impact of CMA on parents and children over time. Families who were still affected continued to experience impact in daily life. Despite development of tolerance, families who were no longer affected revealed continuing nutritional concerns. Follow-ups should be offered even after outgrown CMA to encourage progression to unrestricted diet, to prevent eating disorders and to promote healthy growth.

Abstract
OBJECTIVE To present a brief review of the literature regarding potential racial/ethnic disparities in pediatric food allergy (FA). METHODS Topical review considering data regarding FA prevalence, asthma comorbidity, epinephrine access/use, and psychosocial impact (e.g., burden, quality of life). RESULTS Methodological variation precludes firm conclusions regarding disparities in prevalence; however, some data suggest Black children may be at particular risk. The comorbidity of FA and asthma among urban populations may increase risk of negative outcomes. There are clear racial/ethnic and socioeconomic disparities in epinephrine access and use. Psychosocial measures are frequently validated on samples that are not racially or ethnically diverse. Studies investigating FA's psychosocial impact are often composed of mostly White, non-Hispanic participants (>85% of study sample). CONCLUSIONS Further research is needed to clarify prevalence patterns by race/ethnicity, to investigate the sources of disparity in epinephrine use, and to evaluate the differential impact of FA on diverse children.

Abstract
Cashew nut and other nut allergies can result in serious and sometimes life-threatening reactions. Linear and conformational epitopes within food allergens are important for immunoglobulin E (IgE) binding. Methods that disrupt allergen structure can lower IgE binding and lessen the likelihood of food allergy reactions. Previous structural and biochemical data have indicated that 2S albumins from tree nuts and peanuts are potent allergens, and that their structures are sensitive to strong reducing agents such as dithiothreitol. This study demonstrates that the generally regarded as safe (GRAS) compound sodium sulfite effectively disrupted the structure of the cashew 2S albumin, Ana o 3, in a temperature-dependent manner. This study also showed that sulfite is effective at disrupting the disulfide bond within the cashew legumin, Ana o 2. Immunoblotting and ELISA demonstrated that the binding of cashew proteins by rabbit IgG or IgE from cashew-allergic patients was markedly lowered following treatment with sodium sulfite and heating. The results indicate that incorporation of sodium sulfite, or other food grade reagents with similar redox potential, may be useful processing methods to lower or eliminate IgE binding to food allergens.
