Abstract
Interactions between the nervous system and the immune system play crucial roles in initiating and directing the type 2 immune response. Sensory neurons can initiate innate and adaptive type 2 immunity through their ability to detect allergens and promote dendritic cell and mast cell responses. Neurons also indirectly promote type 2 inflammation through suppression of type 1 immune responses. Type 2 cytokines promote neuronal function by directly activating or sensitizing neurons. This positive neuroimmune feedback loop may not only enhance allergic inflammation but also promote the system-wide responses of aversion, anaphylaxis, and allergen polysensitization that are characteristic of allergic immunity.

Abstract
BACKGROUND Food allergy (FA) affects approximately 8% of children and may be immunoglobulin E (IgE)-mediated or non-IgE-mediated. It is recognized clinically that children with both subtypes of FA may present with features of pediatric feeding disorder (PFD); however, there is currently a limited detail of presenting characteristics. OBJECTIVE The objective of this study was to synthesize the current evidence regarding the feeding characteristics of children with FA, with a focus on the feeding skills and psychosocial domains of PFD. METHOD This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Papers published between 2001 and 2022 describing feeding characteristics in the feeding skills and psychosocial domains in children with FA/history of FA were included. Papers that focused solely on characteristics from the medical or nutritional domains were excluded. Descriptive information regarding demographics, methodology, allergy profile and history, and the characteristics of PFD observed was extracted using a preconceived data extraction form. RESULTS Overall, 40 papers contained descriptions of feeding characteristics of children with non-IgE-mediated FA (n = 22) and IgE-mediated FA (n = 11), while four were nonspecific. In the psychosocial domain, food refusal/aversion, anxiety with eating, and poor intake were the most frequently reported, regardless of FA subtype. Less information was reported regarding feeding skills, although slowness in eating, immature diet, and delays in oral sensory-motor skills were described. CONCLUSIONS Children with FA/history of FA may present with a range of characteristics that map across the feeding skill and psychosocial domains of PFD. Systematic research is needed to fully describe the feeding characteristics of children with FA. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.24562732.

Foods 2023; 12:4083. [PMID: 38002141 PMCID: PMC10670478 DOI: 10.3390/foods12224083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 11/04/2023] [Accepted: 11/08/2023] [Indexed: 11/26/2023] Open
Abstract
Fruit allergies manifest with a diverse array of clinical presentations, ranging from localized contact allergies and oral allergy syndrome to the potential for severe systemic reactions including anaphylaxis. The scope of population-level prevalence studies remains limited, largely derived from single-center or hospital-based investigations. In this comprehensive review, we conducted a systematic literature search spanning the years 2009 to 2023, with full acknowledgment of potential analytical biases, to provide a global overview of fruit allergy prevalence. The primary mechanistic underpinning of fruit allergies stems from cross-reactivity between aeroallergens and food allergens, a consequence of structurally similar epitopes-a phenomenon recognized as pollen food allergy syndrome (PFAS). In the era of molecular allergology, numerous studies have dissected allergen components with substantial clinical relevance. Within this review, we explore important allergenic molecules found in plant-based foods, scrutinize pertinent cross-reactivity patterns, and offer insights into management recommendations. Additionally, we compare guideline recommendations to enhance clinical understanding and inform decision making.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:2196-2207.e13. [PMID: 37088367 DOI: 10.1016/j.jaip.2023.04.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 03/14/2023] [Accepted: 04/10/2023] [Indexed: 04/25/2023]
Abstract
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.

Clin Transl Allergy 2022; 12:e12213. [PMID: 36573312 PMCID: PMC9762119 DOI: 10.1002/clt2.12213] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 10/26/2022] [Accepted: 11/14/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Health-related quality of life (HRQoL) is significantly and substantially reduced in individuals with peanut allergy due to many factors associated with unanticipated or potentially fatal reactions. Further insight on the impact of peanut oral immunotherapy in managing peanut allergy on HRQoL is needed. The aim of this analysis was to assess effects of peanut (Arachis hypogaea) allergen powder-dnfp (PTAH), a biologic drug for peanut oral immunotherapy, on HRQoL from three phase 3 and two follow-on trials of PTAH. METHODS HRQoL assessments from participants aged 4-17 in the PALISADE (ARC003), ARC004 (PALISADE follow-on), ARTEMIS (ARC010), RAMSES (ARC007), and ARC011 (RAMSES follow-on) trials were included in this analysis. Responses on the Food Allergy Quality of Life Questionnaire (FAQLQ) and Food Allergy Independent Measure (FAIM) were evaluated by age group and respondent (self or caregiver proxy). Data were analyzed with descriptive statistics and Student t tests. RESULTS Baseline FAQLQ and FAIM total scores appeared comparable between PTAH- and placebo-treated participants. Self and caregiver proxy-reported total scores on the FAQLQ for PTAH-treated participants generally improved at trial exit versus baseline; FAIM total scores improved throughout all trials. The tendency for improvement in FAQLQ total scores from baseline for PTAH appeared larger in self versus caregiver proxy-reports. Between treatment groups, PTAH was generally favored in the PALISADE and ARTEMIS trials; differences varied in the RAMSES trial based on age and respondent types. CONCLUSIONS PTAH for the management of peanut allergy in children appeared to have a beneficial effect on HRQoL in trials. Improvements were seen despite rigors of trial participation.
