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.

The Allergy to Peanuts imPacting Emotions And Life study (APPEAL) explored the psychosocial burden of living with self-reported peanut allergy experienced by children, teenagers, adults and caregivers in the UK and Ireland. A two-stage (quantitative survey and qualitative interview [APPEAL-1]), cross-sectional study of the psychosocial burden of peanut allergy (APPEAL-2) was conducted. Quantitative data were evaluated using descriptive statistics and qualitative data were analysed using MAXQDA software. A conceptual model specific to UK and Ireland was developed using the concepts identified during the analysis. A total of 284 adults in the UK and Ireland completed the APPEAL-1 survey and 42 individuals participated in APPEAL-2. Respondents reported that peanut allergy restricts their choices in various situations, especially with regard to choosing food when eating out (87% moderately or severely restricted), choosing where to eat (82%), special occasions (76%) and when buying food from a shop (71%). Fifty-two percent of survey participants and 40% of interview participants reported being bullied because of PA. Psychological impact of peanut allergy included feeling at least moderate levels of frustration (70%), uncertainty (79%), and stress (71%). The qualitative analysis identified three different types of coping strategies (daily monitoring or vigilance, communication and planning) and four main areas of individuals' lives that are impacted by peanut allergy (social activities, relationships, emotions and work [adults and caregivers only]). The extent of the impact reported varied substantially between participants, with some reporting many negative consequences of living with peanut allergy and others feeling it has minimal impact on their health-related quality of life. This large survey and interview study highlight the psychosocial burden of peanut allergy for adults, teenagers, children and caregivers in the UK and Ireland. The analysis demonstrates the wide variation in level of impact of peanut allergy and the unmet need for those individuals who experience a substantial burden from living with peanut allergy.
