RESUMO
BACKGROUND: Hen's egg exposure through impaired skin barrier is considered a major mechanism of sensitization to eggs. However, the impact of filaggrin (FLG) gene loss-of-function mutations on the natural history of egg sensitization lacks consensus among studies. OBJECTIVE: To evaluate the association between the natural course of egg sensitization and FLG mutations. METHODS: We used Japanese and the UK birth cohorts (CHIBA and MAAS) to identify the longitudinal patterns of egg sensitization until mid-school age and examined the relationship between the identified patterns and FLG mutations. Sensitization was assessed using egg white-specific IgE levels or skin prick tests (SPTs). Egg allergy was confirmed by parental reports and sensitization. Latent class growth analysis identified longitudinal patterns. RESULTS: Three similar patterns of egg sensitization (persistent, early-onset remitting, and no/low grade classes) were identified in both cohorts, with differing prevalence estimates. The proportion of children with egg allergy in the persistent class at 7 or 8 years of age was 23% (CHIBA) and 20% (MAAS). Consistently in both cohorts, FLG mutations were significantly associated only with the persistent class. Children with FLG mutations had an approximately four-fold increased risk of being in the persistent sensitization class (RRRs: 4.3, 95%C.I. (1.2-16.0), p = .03 in CHIBA; 4.3 (1.3-14.7), p = .02 in MAAS). CONCLUSION: FLG loss-of-function mutations are associated with persistent egg sensitization in both Japanese and European ethnicities, and the mutations might be a potential biomarker for identifying the risk of persistent egg sensitization/allergy in early infancy. Future studies should incorporate oral food challenges to confirm this relationship.
RESUMO
Background: The effectiveness of dietary therapy to induce remission of eosinophilic esophagitis (EoE) has been evaluated over the last decades and summarized in meta-analyses. Choosing the dietary modality, identifying the most suitable patients, and implementing specific prerequisites are essential to ensure long-term success. Summary: Impractical exclusive elemental diets provided the highest remission rates in EoE; however, they are not recommended due to their numerous disadvantages and detrimental effects on patient quality of life. Allergy testing-guided diets for EoE are limited; their insufficient effectiveness and low reproducibility are due to poor accuracy of skin or serum test results in identifying EoE food triggers. Initial experiences with a six-food elimination diet have provided evidence of high and predictive effectiveness rates and paved the way for less restrictive and more efficient step-up approaches, including four-food, two-food, and most recently, milk elimination diets. Dietary treatment for EoE is challenging for patients and families and requires certain skills to ensure success in the short and long term. Key Messages: The selection of appropriate patients is essential to ensure the success of and long-term adherence to dietary treatment of EoE. As normal triggers for EoE are commonly found in the staple diet, it is important to ensure adequate nutritional substitutes to avoid nutrient deficiency risks when long-lasting feeding difficulties or extensive restrictions are present. Specialized facilities in dietary therapy should adopt patient-centered and personalized approaches in order to provide timely monitoring and support for complex cases.
RESUMO
AIMS: Food allergies impose a large clinical and financial burden on patients and the health care system. However, little is known about the factors associated with health care resource use and costs. The aim of this study was to investigate health care resource use and costs in individuals with food allergies utilizing health care in the United States. METHODS: We conducted a retrospective analysis of insurance claims data from the Merative MarketScan Research Databases (indexed from 1 January 2015 to 30 June 2022). All-cause and food allergy-related health care resource use, direct medical, and out-of-pocket costs for medical services were estimated for 12 months post-index using International Classification of Diseases [ICD] codes. RESULTS: Of 355,520 individuals with food allergies continuously enrolled in a health insurance plan for ≥12 months pre- and post-index, 17% had a food allergy-related emergency department visit and 0.9% were hospitalized. The top patient characteristic associated with all-cause and food allergy-related hospitalizations, all-cause costs, and food allergy-related outpatient visit costs was a Charlson Comorbidity Index score of ≥2. Food allergy-related direct medical and out-of-pocket costs were high among patients with a food allergy-related visit. Out-of-pocket cost per patient per year for outpatient visits, emergency department visits, and hospitalizations had an estimated mean of $1631 for patients with food allergy-related visits, which is â¼11% of the total costs for these services ($14,395 per patient per year). LIMITATIONS: Study limitations are primarily related to the nature of claims databases, including generalizability and reliance on ICD codes. Nevertheless, MarketScan databases provide robust patient-level insights into health care resource use and costs from a large, commercially insured patient population. CONCLUSION: The health care resource use of patients with food allergies imposes a burden on both the health care system and on patients and their families, especially if patients had comorbidities.
Some people with food allergies might need extra visits to the doctor or hospital to manage allergic reactions to food, and these visits add to the cost of medical services for both families and for health care providers. Using records of health insurance claims, we looked into the factors affecting medical visits and costs in people with food allergies in the United States. For people with food allergies, having additional medical conditions (measured using the Charleson Comorbidity Index) were linked with extra medical visits and costs. Out-of-pocket costs were high for people who visited a doctor or hospital for their food allergies (costing each person more than $1,600 per year). The total medical cost of food allergy-related care was $14,395 per person per year, paid for by families and health care providers. Our findings might help to better manage and treat people with food allergies and reduce medical costs.

Cow's milk protein can cause food allergy. The different mechanisms of action involved, the clinical variability depending on the stage of pediatric life in which it manifests, leads to difficulties in its approach, with the risk of under- or over-diagnosis. Professionals from various areas intervene in this process and their interaction is recommended. That is why the objective of this consensus has been to reflect the updated knowledge in an interdisciplinary mode, generating recommendations for its correct diagnosis. We have worked with the Delphi method to add to the scientific evidence, the experience from neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology. We think that this interdisciplinary approach will be of practical use and will promote more comprehensive care for these patients.

A rare case of food-dependent exercise-induced anaphylaxis caused by potato snacks is reported. Specific food triggers for anaphylaxis were identified by using the skin prick test, antigen analysis, and serum IgE assays. Four potato proteins were considered candidate antigens for food-dependent exercise-induced anaphylaxis.
RESUMO
BACKGROUND: Adverse reactions to foodstuffs (ARFS), specifically food allergy (FA) and food intolerance (FI), are increasing worldwide and represent a major public health concern. Thus, ARFS management, its identification, evaluation, and intervention, must provide a comprehensive solution. OBJECTIVES: (a) To develop a multifactorial strategy for ARFS management in adults with FA and/or FI; (b) to describe the multiple influential variables in ARFS within the realm of ARFS management; and (c) to design a personalized food allergen-specific substitutive diet (FASSD), as a 6-month dietary treatment option for adults with ARFS and as a component of ARFS management. METHODS: The ALASKA study will consider the following main variables as part of the ARFS management: (1) demographics and clinical information; (2) symptomatology, food and beverages intake and physical activity; (3) hematobiochemical study; (4) immunology; (5) enzymatic activity; (6) anthropometry, body composition, and physical fitness; (7) QoL; (8) 6-month intervention; (9) end of the study; and (10) other assessments. The FASSD will be designed with special emphasis on the commonly lacking micronutrients in the ARFS population: niacin, Mg, K, P, Ca, Zn, B12, folate, Fe, and fiber. DISCUSSION: The ALASKA study protocol has been developed as a global strategy to manage and evaluate ARFS in Spanish adults older than 18 years of age. Approaching ARFS with multiple assessments, as influencing factors, will lead to a novel strategy for ARFS management. The FASSD has been designed as a personalized tool to avoid crucial micronutrient deficiencies that a current strict food allergen avoidance or elimination diet may provoke. TRIAL REGISTRATION: The protocol has been approved by the Ethics Committee of the UPM (REF.20200602) and registered on ClinicalTrials.gov (NCT05802017).

Introduction: Compared to households not managing food allergy, households managing food allergy are faced with greater direct and indirect costs. To address these cost burdens, we developed and piloted a milk allergy-friendly food supplement program for lower- and middle-income households managing a dairy allergy in a child age <6 years. Herein, we aimed to evaluate to the impact of this program on food costs, food security, and caregiver mental health using a longitudinal design. Methods: Participants living in or near the city of Winnipeg, in Manitoba, Canada were recruited from January to February 2022 via social media, word-of-mouth, and a database maintained by the principal investigator. Consenting participants took part in a 6-month allergen-friendly food supplement program that provided them with biweekly deliveries of allergen-friendly foods free of charge. To evaluate the impact of the program on food costs, food security, and well-being, participants completed a series of questionnaires at baseline, mid-point, and at the end of the program. Changes in these variables were assessed via a series of Friedman tests. Results: The final sample was comprised of 8 households. Relative to baseline, participants reported higher total direct food costs at midpoint (+5.6%) and endpoint (+13.5%), but these changes did not reach statistical significance. In contrast, total indirect food costs decreased over the course of the study relative to baseline (midpoint = -28.2%; endpoint = -18.5%), but the changes were not found to be statistically significant. Participants did, however, report a statistically significant decrease in costs related to lost time from work or school as a result of their child's food allergy at endpoint relative to baseline (-100%). Few changes in food security, caregiver well-being, or child food allergy quality of life were noted. Discussion: The provision of allergen-friendly foods helped keep grocery costs below the pace of inflation. Participants also reported reduced costs associated with missed time from work or school as a result of their child's food allergy. Despite these encouraging findings, a relatively high proportion of the current sample reported experiencing food insecurity throughout the study period, suggesting that additional financial support for families is needed.
RESUMO
OBJECTIVE: To explore how the parents of children with atopic dermatitis and allergic diseases such as food allergy, allergic rhinoconjunctivitis, and asthma experience interactions with the Danish healthcare system over time. DESIGN AND METHODS: A qualitative design with individual in-depth interviews. The analysis was inspired by Systematic Text Condensation. SUBJECTS: Eleven parents of children with atopic dermatitis and allergic diseases who received treatment at hospitals in the Capital Region of Denmark. The families had experiences of cross-sectoral patient care. RESULTS: Despite having the same diseases, the children's care pathways were very different. Mapping demonstrated the intricacy of care pathways for this group of children. We identified three aspects that impacted interaction with healthcare: responsibility, tasks, and roles. The families experienced care when the distribution of tasks and responsibilities associated with treatment and system navigation were consistent with both their expectations and their actual experiences. At the same time, families frequently experienced limited collaboration between healthcare professionals resulting in perceived fragmented care and an extended role for parents as care coordinators. Families felt cared for when healthcare professionals knew both their biomedical and biographical circumstances, and adjusted the level of support and care in accordance with the families' particular needs, expectations, and evolving competences. CONCLUSION: We suggest that a possible pathway to improve care may be through a partnership approach as part of family-centered care, with general practitioners having a key role in helping to articulate the individual needs and expectations of each family.

Food allergies severely impact the health-related quality of life (HRQoL) of patients and their caregivers (family or informal caregivers). Currently there is no comprehensive review to provide an overview and critical assessment of the instruments in the field. Six databases were searched from inception until 10 August 2023, and a combination of subject terms and free words was used to search the literature. We used the COnsensus-based Standards for the selection of health Measurement INstruments methodology (COSMIN) to evaluate the measurement properties of the instruments. Forty-one studies reported on ten eligible instruments. Based on COSMIN guidelines, one instrument was recommended for Grade A, and the remaining nine instruments were recommended for Grade B. The Grade A instrument identified, the Food Allergy Quality of Life Questionnaire-Parent Form (FAQLQ-PF), can help researchers assess the effectiveness of treatment for patients with food allergy and to understand the psychosocial impact of the disease on patients.

Objective: Identify countries that have legislation on mandatory declarations of food allergens, irradiated foods, and transgenic foods on the nutritional labels of packaged foods. Methods: Exploratory study reviewing the health regulations and technical standards for foods in Latin American countries in order to gather information on declarations of allergens, trace allergens, irradiated foods, and transgenic foods. The information search was carried out through the countries' government web pages. Presentation of the results is descriptive and narrative. Results: Of the 19 countries reviewed, 89% require a declaration of allergens on their nutrition labeling, 76% have legislation that explicitly require a statement on trace allergens, and 82% follow Codex Alimentarius recommendations with some modifications of food categories. Conclusions: Three pending challenges in the Region are: requiring statements on allergens as a food safety measure; making progress toward improved labeling of trace allergens; and ensuring universal availability of epinephrine.

RESUMO
INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus that can adversely affect the quality of life (QOL) in children. We aim to investigate the burden of EoE on the QOL in children aged 2-18 years and identify factors that influence their QOL. METHOD: A multicenter cross-sectional study was conducted in six Saudi pediatric hospitals. Pediatric Quality of Life 3.0 EoE Module was used to measure the QOL of children with EoE. RESULTS: Thirty-six families (36 parents and 33 children) were enrolled. The most reported symptoms were vomiting (50%), dysphagia (44.4%), and food impaction (36.1%). The mean total score of the parent-proxy report of the Pediatric Quality of Life EoE was 82.9 ± 10.3 versus the children's self-reported score of 77.28 ± 13.6 (p = .043). DISCUSSION: Recurrent emergency department visits were associated with a lower QOL, and a positive family history of EoE was associated with a better QOL.
RESUMO
A 12-year-old girl with severe cow's milk allergy (CMA) was able to safely consume 300 mL of unhydrolyzed cow's milk after three and a half years of oral immunotherapy (OIT) with extensively hydrolyzed milk. The treatment consisted of gradually increasing the intake of hydrolyzed and partially hydrolyzed milk and reintroducing cow's milk. Despite some allergic reactions during treatment, the patient was able to consume more than 200 ml of milk consistently for more than six months without recurrence of symptoms. This case suggests the possibility of an alternative treatment for persistent CMA: not only OIT with cow's milk alone but also a safer introduction to treatment with extensively hydrolyzed formulas.
RESUMO
BACKGROUND: Legumes belonging to the family Fabaceae of the order Fabales are a widely consumed source of protein. IgE-mediated hypersensitivity reactions to legumes have been described, the most studied allergens being peanuts and soybeans. In the Mediterranean region and India, lentils, chickpeas and peas have been considered important allergens and legumes have been reported to represent the fifth most common cause of food allergy in children under 5 years of age in Spain. In Latin America, there are few reports of allergy to legumes other than peanuts, and these are especially in the paediatric population. OBJECTIVE: To describe a case of IgE-mediated legume allergy in an adult female patient. CASE REPORT: We describe the case of a 65-year-old female patient who reports a 20-year history of generalized urticaria, accompanied by angioedema and dyspnea occurring immediately after consumption of lentils, beans, chickpeas, soya beans and cold meats, requiring admission to the emergency department for this cause. Tolerates peanuts. She does not report anaphylaxis in any context other than those described. He has presented generalized pruritus with exposure to fumes from cooking beans. Pathological history: Hypertension, type II diabetes mellitus, hypothyroidism. Allergic: Anaphylaxis due to penicillin at the age of 30. Other history: extensive local reaction to hymenoptera sting. Prick test trophoallergens: soya 3 mm. Prick to prick protein based on commercial soybean 7mm, chickpea 5mm, lentil 6mm and bean 7mm. He was negative for wheat and peanut (Image 1) (Attached in separate file). It has a normal tryptase report. Indication was given for adequate adrenaline and strict avoidance of legumes, except peanuts. CONCLUSIONS: Legume allergy is little known in our environment and mainly affects children. Clinical manifestations include mild reactions and anaphylaxis. A high degree of cross-reactivity among legumes has been reported. Lentils have cross-reactivity with chickpeas and beans. Peanut allergy may also be associated with allergy to lentils, chickpeas, and peas, but is less frequently reported.
ANTECEDENTES: Las leguminosas pertenecientes a la familia Fabaceae del orden Fabales, son una fuente de proteína de amplio consumo. Se han descrito reacciones de hipersensibilidad mediadas por IgE a las leguminosas, siendo los alérgenos más estudiados el maní y la soya. En la región mediterránea y en India, las lentejas, garbanzos y arvejas se han considerado alérgenos importantes, y se ha informado que las leguminosas representan la quinta causa más común de alergia alimentaria en niños menores de cinco años en España. En América Latina, hay pocos reportes de alergia a las leguminosas diferentes al maní, y éstos son, especialmente, en población pediátrica. OBJETIVO: Describir el caso de alergia mediada por IgE a leguminosas, en una paciente adulta. REPORTE DE CASO: Se describe el caso de una paciente de 65 años, quien reporta un cuadro de 20 años con evolución consistente de urticaria generalizada, acompañada de angioedema y disnea, que ocurre, en forma inmediata, tras el consumo lentejas, fríjoles, garbanzos, soya y carnes frías; y requiere de ingresos al servicio de urgencias por esta causa. Tolera maní. No se reporta anafilaxia en otro contexto diferente a los descritos. Ha presentado prurito generalizado con la exposición a vapores de la cocción de fríjoles. Antecedentes patológicos: hipertensión arterial, diabetes mellitus tipo II, hipotiroidismo. Alérgicos: Anafilaxia por Penicilina a los 30 años. Otros antecedentes: Reacción local extensa con picadura de himenópteros. Prick test trofoalérgenos: soya 3 mm. Prick to prick proteína a base de soya comercial 7mm, garbanzo 5mm, lenteja 6mm y fríjol 7mm. Fue negativa para trigo y maní (Imagen 1). (Adjunta en archivo separado). Tiene reporte de triptasa normal. Se dio indicación de porte adecuado de adrenalina y evitación estricta de leguminosas, excepto maní. CONCLUSIONES: La alergia a las leguminosas es poco conocida en nuestro medio, y afecta principalmente a los niños. Sus manifestaciones clínicas incluyen reacciones leves y anafilaxia. Se ha informado, un alto grado de reactividad cruzada entre las leguminosas. Las lentejas tienen reactividad cruzada con garbanzos y fríjoles. La alergia al maní también puede estar asociada con la alergia a lentejas, garbanzos y guisantes, pero se informa con menos frecuencia.

A large and growing corpus of epidemiologic studies suggests that the population-level burden of pediatric FA is not equitably distributed across major sociodemographic groups, including race, ethnicity, household income, parental educational attainment, and sex. As is the case for more extensively studied allergic disease states such as asthma and atopic dermatitis epidemiologic data suggest that FA may be more prevalent among certain populations experiencing lower socioeconomic status (SES), particularly those with specific racial and ethnic minority backgrounds living in highly urbanized regions. Emerging data also indicate that these patients may also experience more severe FA-related physical health, psychosocial, and economic outcomes relating to chronic disease management. However, many studies that have identified sociodemographic inequities in FA burden are limited by cross-sectional designs that are subject to numerous biases. Compared with cross-sectional study designs or cohorts established later in life, birth cohorts offer advantages relative to other study designs when investigators seek to understand causal relationships between exposures occurring during the prenatal or postnatal period and the atopic disease status of individuals later in life. Numerous birth cohorts have been established across recent decades, which include evaluation of food allergy-related outcomes, and a subset of these also have measured sociodemographic variables that, together, have the potential to shed light on the existence and possible etiology of sociodemographic inequities in food allergy. This manuscript reports the findings of a comprehensive survey of the current state of this birth cohort literature and draws insights into what is currently known, and what further information can potentially be gleaned from thoughtful examination and further follow-up of ongoing birth cohorts across the globe.

OBJECTIVE: To identify the out-of-pocket expenses and parent-reported quality of life (QoL) of children with a diagnosis of cow's milk protein allergy between the ages of 0 and 5 using the Food Allergy Quality of Life Questionnaire - Parent Form. METHODS: A cross-sectional study was conducted in two tertiary care centers in Bogotá. Demographic, medical information, and QoL scores were collected by parental interview. We carried out a cost-of-illness analysis based on self-reported out-of-pocket expenses attributed to the treatment as a whole and the family's monthly income. Exploratory analyses used the QoL scores and the percentage of out-of-pocket expenses attributable to treatment as outcomes. RESULTS: 122 families were analyzed. Median subject age was 17 months (Q1-Q3: 11-26.75 months) and female subjects made up 71% of the sample. The median QoL score was 3.21 points (Q1-Q3: 2.43-4.34) and only differed by age groups and personal history of other food allergies. The median out-of-pocket treatment related costs was 300,000 Colombian pesos (COP) (Q1-Q3: 280,000-340,000 COP). About 17% of the families had to pay over 15% of their monthly income to purchase food and dietary products. Out-of-pocket treatment related costs differed depending on whether the treatment included formulas (Mann-Whitney test p < 0.001). Out-of-pocket treatment expenses were uncorrelated with the QoL scores. CONCLUSION: Food allergy related QoL scores were not associated with out-of-pocket expenses as a whole or as a fraction of monthly income but were higher in children with additional food allergies and in older age groups, suggesting a lower QoL.

Background: Food allergies impose a large psychosocial burden, including mental, emotional, and social aspects, on both patients and their caregivers. Patients, caregivers, and their families often experience anxiety, isolation, and fear around food allergies. Objective: To assess the real-world mental health burden of food allergies, using the Food Allergy Research & Education (FARE) Patient Registry (NCT04653324). Methods: Self-reported data from patients with food allergies, and their caregivers, were analyzed from the FARE Food Allergy History and Mental Health Concerns surveys. Odds ratios were also calculated as a measure of association between patient food allergy characteristics and the likelihood of having mental health concerns or a formal mental health diagnosis. Results: The FARE Patient Registry included 1680 patients/caregivers. Anxiety (54%) and panic (32%) were the most common emotions that patients reported as a result of eating the food that produced an allergic reaction. About two-thirds of patients reported mental health concerns related to food allergies (62%), including anxiety after an allergic reaction, anxiety about living with food allergies, and concerns about food avoidance. Caregivers also experienced fear for the safety of their children, and often sought mental health care to cope with worry related to caring for patients with food allergies. The likelihood of having food allergy-related mental health concerns was increased for patients experiencing more than 1 reaction per year (OR 1.68-1.90) and was lowered for patients having a formal mental health diagnosis (OR 0.43). Caregivers filling out the FARE survey for pediatric patients (OR 4.03) and experiencing food allergy-related mental health concerns (OR 2.36) were both significant predictors for having a formal mental health diagnosis. Conclusion: Our study highlights a continuing unmet need for mental health screening and support as part of the management of patients with food allergies.
RESUMO
BACKGROUND: Hypersensitivity reactions (HR) are common in mastocytosis. However, little is known about triggers and risk factors. The registry of the European Competence Network on Mastocytosis (ECNM) enables reliable studies in a larger cohort of mastocytosis patients. We assessed prevalence, triggers and risk factors of HR in adults with mastocytosis in the ECNM registry. METHODS: Data were collected in 27 ECNM centers. We analyzed potential triggers (Hymenoptera venoms, food, drug, inhalant and others) and risk factors at diagnosis and during follow-up. The study group consisted of 2485 adults with mastocytosis, 1379 women (55.5%) and 1106 men (44.5%). Median age was 48.2 years (range 18-91 years). RESULTS: Nine hundred and forty eight patients (38.1%) reported one or more HR`. Most common triggers were Hymenoptera venoms in cutaneous mastocytosis (CM) and indolent systemic mastocytosis (ISM), whereas in advanced SM (advSM), most common elicitors were drugs, including nonsteroidal anti-inflammatory agents and penicillin. In multivariate analyses, tryptase level < 90 ng/mL, <15% infiltration by mast cells in bone marrow biopsy-sections, and diagnosis of ISM were identified as independent risk factors for HR. For drug-induced HR, prominent risk factors were advSM and high tryptase levels. New reactions were observed in 4.8% of all patients during 4 years follow-up. CONCLUSIONS: HR are mainly triggered by Hymenoptera venoms in patients with CM and ISM and by drugs in patients with advSM. Tryptase levels <90 ng/mL, mast cell bone marrow infiltration <15%, and WHO category ISM are predictors of HR. New HR occur in 4.8% of all patients within 4 years.
RESUMO
Abstract Objectives To review and discuss the role of an elimination diet in food-allergic children, emphasizing nutritional aspects for a better practical approach. Sources Non-systematic review of the literature. Findings Under an elimination diet, food-allergic patients may suffer from growth impairment or obesity and compromised quality of life. Disease phenotype, age, type, number of foods excluded, comorbidities, eating difficulties, economic status, and food availability must be considered for an appropriate diet prescription. Diet quality encompasses diversity and degree of food processing, which may alter immune regulation. Conclusions A friendly food elimination diet prescription depends on a multidisciplinary approach beyond macro and micronutrients.
