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

Project description:(1) Background: Food allergy (FA) is an immune-mediated hypersensitivity to foods, significantly contributing to childhood morbidity and mortality. This study aimed to assess the prevalence, characteristics, and influencing factors of parent-reported FAs among children in Saudi Arabia. (2) Methods: This cross-sectional study utilized a validated parental questionnaire distributed across all regions of Saudi Arabia. Data from 2130 participants were collected and analyzed using SPSS v. 26 and Prism software v. 10.3.0. (3) Results: Parent-reported FA prevalence was 15.2%. Egg was the most common allergen (6.2%), followed by tree nuts (4.1%), peanuts (4.0%), milk (3.8%), and sesame (3.2%). Significant geographical variations were observed, with the western region having the highest burden (p < 0.001). Older children had higher rates of shellfish and fish allergies. Parental allergies and co-existing asthma/drug allergies were positively associated with childhood FAs. (4) Conclusions: This study highlights a substantial burden of parent-reported FAs in Saudi Arabia, with regional variations in food allergen distribution. Parental allergies and co-existing allergic conditions may influence FA risk.

Project description:IgE-associated food allergy affects approximately 3% of the population and has severe effects on the daily life of patients-manifestations occur not only in the gastrointestinal tract but also affect other organ systems. Birth cohort studies have shown that allergic sensitization to food allergens develops early in childhood. Mechanisms of pathogenesis include cross-linking of mast cell- and basophil-bound IgE and immediate release of inflammatory mediators, as well as late-phase and chronic allergic inflammation, resulting from T-cell, basophil, and eosinophil activation. Researchers have begun to characterize the molecular features of food allergens and have developed chip-based assays for multiple allergens. These have provided information about cross-reactivity among different sources of food allergens, identified disease-causing food allergens, and helped us to estimate the severity and types of allergic reactions in patients. Importantly, learning about the structure of disease-causing food allergens has allowed researchers to engineer synthetic and recombinant vaccines.

Project description:BackgroundManagement of patients with food allergies is complex, especially in cases of patients with multiple and potentially severe food allergies. Although international guidelines exist for food allergy management, the role of the allergist in the decision-making process is key.ObjectiveOur aim was to investigate the management patterns and educational needs of practicing allergists treating patients with food allergies.MethodsAn online survey was e-mailed to United States-based practicing allergists (N = 2833) in November-December 2021. The allergists were screened for managing 1 or more patients (including ≥25% pediatric patients) with food allergies per month. The allergists responded to questions regarding food allergy management in response to 2 hypothetical pediatric case studies, their familiarity with available guidelines and emerging treatments, and their future educational preferences. A descriptive analysis of outcomes was conducted.ResultsA total of 125 responding allergists (4.4%) met the eligibility criteria and completed the survey. The allergists prioritized written exposure action plans, patient-caregiver communication, prevention of serious reactions, and consideration of both food allergy severity and allergic comorbidities in the management of patients with food allergies. With regard to recommending biologics in the future, the allergists identified patient history of anaphylaxis and hospitalizations, food allergy severity, and allergic comorbidities as all being important factors to consider when deciding on appropriate treatment options. The allergists noted their ongoing educational needs, especially for current and emerging treatments for food allergies.ConclusionWith the treatment landscape for food allergies evolving rapidly, the decision-making priorities and continuing educational needs of allergists will be important in optimizing the management of patients with food allergies.

Project description:BackgroundParents of children with food allergies (CwFA) experience reduced quality of life (QoL) and may have reduced access to in-person interventions in the COVID-19 pandemic. This trial developed and evaluated an online, self-help, information provision website, aimed at improving QoL in parents of CwFA.MethodsIn a single-blinded, randomised controlled trial (RCT), participants were randomised to either receive access to the website or a waiting-list control. At baseline, post-intervention (week 4) and follow-up (week 8), measures of parental food allergy-related QoL, depression, anxiety, stress, intolerance of uncertainty (IU) and self-efficacy were obtained.ResultsA total of 205 participants were randomised; 97% were females, 91% white and 78% educated ≥ degree level, with a mean age of 38.95 years (SD = 6.89). 44.9% (n = 92) were retained at follow-up. The arms did not significantly differ on any outcome at any time point. For a sub-group of participants above the clinical cut-off for depression at baseline, the intervention may have improved QoL. Participants reported the website content as useful and accessible, but accessed it infrequently. In baseline data, IU and self-efficacy were significantly associated with QoL.ConclusionWhile the COVID-19 pandemic has encouraged greater provision of online interventions, our RCT suggests this particular website is not suitable for this population in general, although future research could examine its efficacy for depressed parents of CwFA, to increase confidence that the sub-group finding was not a Type 1 error. The baseline data suggest IU and self-efficacy remain potential proximal targets for intervention.

Project description:BackgroundFood allergy (FA) can have serious psychosocial and economic repercussions on food-allergic children and their caregivers and be associated with negative effects on their quality of life. Food allergen immunotherapy (IT) is a promising experimental therapy but can be linked to anxiety. This study investigated the effects of IT on FA-specific health-related quality of life (HRQL) over a 24 month-follow-up in caregivers of children with single and multiple food allergies. We hypothesized that characteristics such as age, asthma at baseline and respiratory allergic reactions during therapy were key characteristics that influenced HRQL scores.MethodsA validated Food Allergy Quality of Life - Parental Burden Questionnaire (FAQL-PB) was used to assess HRQL. It was randomly distributed to and filled out by caregivers of 57 food-allergic children enrolled in clinical trials of IT. The same parent answered the FABQL-PB questionnaire at baseline and for 6-month, 12- month, 18- month, and 24-month time points on IT.ResultsCaregiver HRQL improved significantly (change < - 0.5, p <0.0001) at each follow-up time point compared to baseline. The percentages of caregivers with improvement in HRQL progressively increased (92% at 24 month-follow-up time point compared to baseline). HRQL improved more in caregivers of participants older than 10 years or desensitized to more than 4 food allergens than those who were not (p <0.0001). Caregivers of participants with pre-existing asthma or dose-related respiratory allergic reactions had less improvement in HRQL than those who did not (p <0.01).ConclusionIT lead to improvement in caregiver HRQL. Certain characteristics were associated with greater improvements in caregiver HRQL.

Project description:We examined whether cesarean delivery (CD) increased the risk of wheeze or food allergy in early childhood compared with vaginal delivery and whether these associations were mediated by breastfeeding. The study population was the Upstate KIDS cohort (2008-2010) of mothers and infants from the State of New York (excluding New York City). Infant's wheeze was reported by questionnaire every 4-6 months until 3 years of age, as were food allergies beginning at 8 months. Modified Poisson regression was used to compare risks of the outcomes according to mode of delivery (MOD). Potential confounders were identified a priori using directed acyclic graphs. Emergency CD (n = 1,356) was associated with elevated risk of wheeze, adjusting for pregnancy complications, maternal atopy, gestational age, birth weight, and smoking during pregnancy (risk ratio = 2.47, 95% confidence interval: 1.31, 4.66), and an increased risk of food allergy, adjusting for maternal atopy, prepregnancy body mass index, smoking during pregnancy, and parity (risk ratio = 3.02, 95% confidence interval: 1.26, 7.25). Neither outcome was significantly associated with planned CD (n = 1,565 infants). Breastfeeding mediated the association between MOD and wheeze but not food allergy. Other factors not associated with early-life microbial transfer, but relating to the development of the outcomes, might contribute to the association between MOD and wheeze/food allergy.

Project description:Background-Objective: With recent evidence suggesting that growth is no longer considered a major issue in children with food allergies (FA) on elimination diet, priority has shifted to diet quality to establish healthy eating patterns and prevent non-communicable diseases. The Diet Quality Index - International (DQI-I) could be useful for assessing the overall diet quality of FA-children. This study aimed to evaluate the impact of elimination diet on DQI-I in children with FA and the accuracy of DQI-I in reflecting nutrient intake. Materials-methods: In a prospective, cross-sectional, cohort study of FA-children (2-14 years), nutritional intake was evaluated using a 7-day food frequency questionnaire, 24-h dietary recall, and the DQI-I. Results: Of the 76 children recruited, 44.7% had multiple allergies. Mean overall DQI-I score was 52 points, with only 28% of participants having good overall DQI-I (≥60 points). DQI-I moderation and balance were the most affected domains. Participants with multiple allergies had higher DQI-I moderation and balance and lower vitamin D and Ca intake. Compared to toddlers, schoolchildren had higher DQI-I variety and lower moderation and received higher vitamin B2, vitamin B12, Ca, P, and Zn. The number of allergies, age, and milk avoidance were independently associated with adjusted DQI-I moderation and balance, energy, and certain micronutrient intake. Higher percentages of participants with good DQI-I received adequate amounts of Mn and vitamins A, B6, C, and folate than those with poor DQI-I. Conclusions: In children with FA on elimination diet, the DQI-I accurately captured the deflection of diet quality related to the development of chronic, non-communicable diseases through its moderation and balance components. This is DQI-I's main purpose as a healthy diet indicator and as such it would be a useful tool responding to the needs of the contemporary shifting of priorities in FA-children's diet from quantity to quality. Nevertheless, it does not accurately reflect the intake of certain micronutrients potentially compromised by elimination diets. Therefore, regular nutritional assessment utilizing both the DQI-I and tools assessing individual nutrient intakes along with professional nutrition counseling should be integral parts of the individualized management of children with FA to ensure adequate nutrient intake and establish healthy dietary patterns.

Project description:Food allergies are an increasingly public health problem, affecting up to 10% of children and causing a significant burden on affected patients, resulting in dietary restrictions, fear of accidental ingestion and related risk of severe reactions, as well as a reduced quality of life. Currently, there is no specific cure for a food allergy, so the only available management is limited to strict dietary avoidance, education on prompt recognition of symptoms, and emergency treatment of adverse reactions. Several allergen specific- and nonspecific-therapies, aiming to acquire a persistent food tolerance, are under investigation as potential treatments; however, to date, only immunotherapy has been identified as the most promising therapeutic approach for food allergy treatment. The aim of this review is to provide an updated overview on changes in the treatment landscape for food allergies.
