Abstract
AIM Examining health-related quality of life (HRQoL) is important to improve patient care. In this study, we translate and evaluate the Finnish versions of the Food Allergy Specific Quality of Life Questionnaires (FAQLQs) from a Finnish perspective and undertake a detailed evaluation of the 10-question Parent Form Questionnaire (FAQLQ-PF10). METHODS This validation study was performed to evaluate the Finnish versions of the FAQLQs. Validation was performed by analysing clinical characteristics, factor loadings and Cronbach's α reliability estimates. The inclusion criteria for participants in this study were having a doctor-diagnosed food allergy or being a parent of a child with a doctor-diagnosed food allergy and being able to answer the questionnaire in Finnish. RESULTS Altogether, 247 questionnaires were completed in this study. Most of the respondents had multiple food allergies (77%, 189/247). Spearman's correlations related to the 10-question parent form (FAQLQ-PF10), the 30-question parent form (FAQLQ-PF) and the Food Allergy Severity Measurement-Parent Form (FAIM-PF) were statistically significant (p value = 0.000-0.007). The reliability of the Finnish versions of the FAQLQs measured by Cronbach's α was overall good (0.75-0.981). CONCLUSION The Finnish versions of the FAQLQs are reliable and suitable to use, and the FAQLQ-PF10 has good usability.

Abstract
The existence of long-lived IgE antibody-secreting cells (ASC) is contentious, with the maintenance of sensitization by the continuous differentiation of short-lived IgE+ ASC a possibility. Here, we review the epidemiological profile of IgE production, and give an overview of recent discoveries made on the mechanisms regulating IgE production from mouse models. Together, these data suggest that for most individuals, in most IgE-associated diseases, IgE+ ASC are largely short-lived cells. A subpopulation of IgE+ ASC in humans is likely to survive for tens of months, although due to autonomous IgE B cell receptor (BCR) signaling and antigen-driven IgE+ ASC apoptosis, in general IgE+ ASC probably do not persist for the decades that other ASC are inferred to do. We also report on recently identified memory B cell transcriptional subtypes that are the likely source of IgE in ongoing responses, highlighting the probable importance of IL-4Rα in their regulation. We suggest the field should look at dupilumab and other drugs that prohibit IgE+ ASC production as being effective treatments for IgE-mediated aspects of disease in most individuals.

Int Arch Allergy Immunol 2023; 184:1203-1215.

Abstract
INTRODUCTION Oral immunotherapy (OIT) imposes a burden on parents and their children with food allergies (FAs). We already developed a questionnaire for OIT-related Parental Burden (OIT-PB) scale. However, the previous questionnaire had some problems. This study modified OIT-PB and verified its reliability and validity. METHODS A 20-item draft covering the physical and mental burdens caused by OIT was prepared jointly with multiple allergists. The Food Allergy Quality of Life Questionnaire-Parental Burden (FAQLQ-PB) and Stress Response Scale-18 (SRS-18) were used to verify concurrent validity. A questionnaire survey was administered during treatment to parents of FA children who had started OIT for the first time. An additional OIT-PB survey was performed at one specific institution 1 week after the posttreatment survey. RESULTS The responses of 64 of the 76 recruited parents were analyzed. Of the 20 questions, 1 item was excluded owing to the floor effect, 1 was excluded because its commonality was less than 0.2, and 2 were excluded because their factor loading values were less than 0.4. Factor analysis was used to classify the OIT-PB into the following 4 subscales: "burden caused by adherence to treatment plan," "anxiety about symptom-induced risk," "burden due to patient's eating behavior," and "anxiety about treatment effect." The Cronbach's α for all 16 items of the OIT-PB was 0.893; Cronbach's α for each subscale was 0.876, 0.898, 0.874, and 0.717. The re-test reliability coefficient was 0.864 (95% confidence interval [CI]: 0.720-0.937, p < 0.001). A significant positive correlation was found between the OIT-PB and FAQLQ-PB (R = 0.610 [95% CI: 0.422-0.747], p < 0.001) and the SRS-18 (R = 0.522 [95% CI: 0.306-0.687], p < 0.001). A significant negative correlation was found between the rate of increase in OIT food intake and the "anxiety about treatment effect" score (R = -0.355 [95% CI: -0.558-0.112], p < 0.001). Parents of children on the hen's egg OIT treatment scored higher on the "burden due to patient's eating behavior" subscale than did parents of children on the milk and wheat OIT treatment. CONCLUSION The burden of OIT experienced by parents can be broadly classified into four categories. The modified OIT-PB was able to evaluate them individually and was shown to have reliability and validity. This scale is expected to be useful in the development of OIT that considers not only therapeutic effect but also the burden experienced by FA children and their parents.

Mechanisms and biomarkers of successful allergen-specific immunotherapy. Asia Pac Allergy 2022; 12:e45. [PMID: 36452016 PMCID: PMC9669467 DOI: 10.5415/apallergy.2022.12.e45] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 10/30/2022] [Indexed: 11/22/2023] Open
Abstract
Allergen-specific immunotherapy (AIT) is considered the only curative treatment for allergic diseases mediated by immunoglobulin E (IgE). Currently, the route of administration depends both on the different types of causal allergens and on its effectiveness and safety profile. Several studies have reported the mechanisms and changes in humoral and cellular response underlying AIT; however, the full picture remains unknown. Knowledge of who can benefit from this type of treatment is urgently needed due to the patient safety risks and costs of AIT. In vivo or in vitro biomarkers have become a strategy to predict clinical outcomes in precision medicine. There are currently no standardized biomarkers that allow determining successful responses to AIT, however, some studies have found differences between responders and nonresponders. In addition, different candidates have been postulated that may have the potential to become biomarkers. In this review, we aim to summarize the findings to date related to biomarkers in different IgE-mediated allergic diseases (respiratory, food, and venom allergy) with the potential to define who will benefit from AIT.
