Infantile atopic dermatitis - increasing severity predicts negative impacts on maternal and infant sleep: a mixed methods study.

BACKGROUND: While the impacts of atopic dermatitis (AD) on maternal and child sleep outcomes have been previously explored, less is known about the associations between infantile AD and sleep quality and quantity. OBJECTIVE: To describe the perceived causes of AD-associated maternal sleep disturbances and the association between AD severity and infant sleep outcomes. METHODS: Mothers with infants aged < 19 months old with a diagnosis of AD were recruited from social media and medical clinics in Winnipeg, Canada between October 2021 and May 2022. Infant AD severity was classified using maternal-reported data on the Patient-Oriented Scoring Atopic Dermatitis tool (PO-SCORAD). Quantitative data were collected via a series of questionnaires with a subset of mothers subsequently completing semi-structured interviews. Quantitative and qualitative data were integrated in the discussion. RESULTS: Mothers of infants with moderate/severe AD (6/12) were more likely to report their infant suffering from a higher degree of sleeplessness (i.e., ≥ 5 on a scale of 0-10) over the past 48 h compared to mothers of infants with mild AD (0/18). This was supported by qualitative findings where mothers described how their infant's sleep quality and quantity worsened with AD severity. Additionally, 7/32 mothers reported that their child's AD, regardless of severity, disturbed their sleep. Maternal sleep loss was most commonly attributed to infant itching (6/7), followed by worry (4/7). CONCLUSION: Infantile AD severity was associated with worse sleep outcomes for both mothers and infants. We propose that maternal and infantile sleep quality and quantity can be improved by reducing AD severity through adherence to topical treatments.

Core Outcome Set for IgE-mediated food allergy clinical trials and observational studies of interventions: International Delphi consensus study 'COMFA'.

BACKGROUND: IgE-mediated food allergy (FA) is a global health concern with substantial individual and societal implications. While diverse intervention strategies have been researched, inconsistencies in reported outcomes limit evaluations of FA treatments. To streamline evaluations and promote consistent reporting, the Core Outcome Measures for Food Allergy (COMFA) initiative aimed to establish a Core Outcome Set (COS) for FA clinical trials and observational studies of interventions. METHODS: The project involved a review of published clinical trials, trial protocols and qualitative literature. Outcomes found as a result of review were categorized and classified, informing a two-round online-modified Delphi process followed by hybrid consensus meeting to finalize the COS. RESULTS: The literature review, taxonomy mapping and iterative discussions with diverse COMFA group yielded an initial list of 39 outcomes. The iterative online and in-person meetings reduced the list to 13 outcomes for voting in the formal Delphi process. One more outcome was added based on participant suggestions after the first Delphi round. A total of 778 participants from 52 countries participated, with 442 participating in both Delphi rounds. No outcome met a priori criteria for inclusion, and one was excluded as a result of the Delphi. Thirteen outcomes were brought to the hybrid consensus meeting as a result of Delphi and two outcomes, 'allergic symptoms' and 'quality of life' achieved consensus for inclusion as 'core' outcomes. CONCLUSION: In addition to the mandatory reporting of adverse events for FA clinical trials or observational studies of interventions, allergic symptoms and quality of life should be measured as core outcomes. Future work by COMFA will define how best to measure these core outcomes.

Infantile atopic dermatitis and maternal-infant bonding: a mixed methods study.

BACKGROUND: Childhood atopic dermatitis can have a negative effect on caregivers' quality of life and stress levels due to the burdensome nature of its treatment. Given that the condition often emerges in infancy, atopic dermatitis-related stress also carries the potential to negatively affect the developing mother-infant bond. While it is plausible that atopic dermatitis has a negative impact on maternal-infant bonding, these relationships have not been studied directly. In light of this gap, the current study investigated the association between infantile atopic dermatitis and the maternal-infant bond using a mixed-method design. METHODS: Mothers of infants (< 19 months) with atopic dermatitis were recruited from social media and medical clinics between October 2021 and May 2022. Mothers with infants unaffected by inflammatory skin conditions were also recruited to serve as a control group. Participants were asked to complete questionnaires related to their demographics, child's health, and mother-infant bond. Multiple linear regression analyses were used to assess bonding quality among cases and controls. A subset of cases were also asked to participate in semi-structured interviews focused on infantile atopic dermatitis and the maternal-infant bond. RESULTS: The final sample consisted of 32 cases and 65 controls. Scores on the impaired bonding and risk of abuse subscales did not significantly differ between cases and controls. However, mothers of infants with atopic dermatitis did report lower levels of caregiving anxiety (b = - 1.47, p < 0.01) and pathological anger/rejection (b = - 1.74, p = 0.02) relative to controls. Qualitative findings suggest that the topical therapies required to manage atopic dermatitis may strengthen the bond between some mothers and infants. CONCLUSION: Findings suggest that atopic dermatitis does not have a negative impact on maternal-infant bonding and may actually improve bonds in some cases. In light of this finding, clinicians may leverage the potentially positive impact of atopic dermatitis-related caregiving on the maternal-infant bond to encourage caregivers to remain adherent to their child's topical treatments.

Parental perceptions of a novel subsidy program to address the financial burden of milk allergy: a qualitative study.

BACKGROUND: Approximately 6-7% of Canadian children have food allergy. These families face substantial burdens due to the additional costs incurred purchasing allergy-friendly products necessary for management compared to families without food allergies. In the year prior to the COVID-19 pandemic, these costs were equivalent to an average of $200 monthly compared to families without food allergy. As food prices continue to rise, rates of food insecurity also increase, disproportionately affecting households with food allergy who have limited choices at food banks. METHODS: Families living or working in Winnipeg, Canada with an annual net income of about $70,000 or less the year prior to recruitment and a child under the age of 6 years old with a physician diagnosed milk allergy were recruited between January and February 2022. Participating families received bi-weekly home deliveries for six months, from March to August 2022, of subsidy kits containing ~$50 worth of milk allergy-friendly products. Semi-structured interviews, completed ± 2 weeks from the final delivery, were audio-recorded, transcribed verbatim, and analyzed thematically. RESULTS: Eight interviews, averaging 32 min (range 22-54 min), were completed with mothers from all different families. On average, mothers were 29.88 ± 4.39 years old and children were 2.06 ± 1.32 years old. All children reported allergies in addition to milk. Based on the data from these interviews, we identified 3 themes: food allergy causes substantial burden for families, "I have to get his allergy-friendly food first before getting to my basic needs", and perceived emotional and financial benefits of a milk allergy-friendly food subsidy program. CONCLUSIONS: This study, along with previous research, suggests that there is a need for assistance for families managing milk allergies. It also provides important information to inform development of programs which can address these financial challenges. Our in-kind food subsidy was perceived as having a positive impact on food costs and stress associated with food allergy management, however, parents identified a need for more variety in the food packages. Future programs should strive to incorporate a greater variety of products to address this limitation.

Determining the benefits and drawbacks of parents using personal connections and social networks for recruitment in research projects: a qualitative study.

BACKGROUND: It is becoming more common for parents of children with chronic conditions to join research teams as partners. Parent partnerships can help align research with what is relevant and important to families. It is also common for parent partners to be asked to share information about a study through their personal networks, which supports study recruitment. In this parent-led study, we explored parents' experiences when working together with researchers in patient-oriented research studies, in relation to study recruitment. METHODS: Demographic data were collected through a brief online survey (SurveyMonkey®) and analysed descriptively (n, %, median (interquartile range; IQR)). Qualitative data were collected through focus groups and interviews (July to October 2021), transcribed verbatim, and analysed thematically. Parent co-leads were involved in every stage of the study, including study design, recruitment, data collection, analysis, interpretation, and knowledge mobilization. RESULTS: Fifteen parents (n = 14 women) who had research partnership experience participated in this study. Most (n = 13) participants self-identified as White or of European descent. The majority (n = 10) had partnered in 1-3 research projects, while five participants had partnered in 4 + projects. Parents had a median of 3 years (IQR: 5) of partnership experience. We identified the following three themes: motivations, authentic partnerships, and learned decision making. Each theme included reflections about recruitment, and about research partnership in general. Motivations included a personal connection to the research topic, a connection to the community impacted by the research topic, and a desire to create change. Authentic partnerships were important for a meaningful experience, and enhanced participant's willingness and ability to share study materials. Learned decision making reflected parents' evolving decisions and practices related to sharing study information or personal information to support research. We provide a summary of participants' recommendations for researchers who work with parent partners, and recommendations for parents as they approach research partnerships. CONCLUSIONS: Experiences shared by parents who have partnered in research provide valuable information to inform recruitment methods and improve team functioning. Parent partners expressed a willingness to support recruitment and valued a strong research team working together for a common outcome. This study yields a set of recommendations guiding future research that engages parents as team members.

It is becoming common for parents of children with chronic conditions to join research teams as partners. These partnerships help ensure that research is relevant to families. In partnership roles, parents are often asked to share information through their personal networks to support recruitment. In this parent-led study, we explored parents' experiences related to sharing research information through their personal networks. Through interviews and focus groups, our team asked 15 parents with research partnership experience how they felt about using their personal connections to help recruit for research. Interviews and focus group recordings were transcribed. We looked at the data to find common patterns, or themes, and found three: motivations, authentic partnerships, and learned decision making. Each theme included reflections about recruitment, and about research partnership in general. Motivations included a personal connection to the research topic, a connection to the community impacted by the topic, and the desire to create change. Authentic partnerships were important for a meaningful experience, and enhanced participant's willingness to share study recruitment materials. Learned decision making reflected parents' evolving decisions and practices related to sharing study information or personal information to support research. We provide a summary of participants' recommendations for researchers who work with parent partners, and for parents as they consider partnerships. Experiences shared by parents who have partnered in research provide valuable information to inform recruitment methods and improve team functioning. Parent partners expressed a willingness to support recruitment and valued a strong research team working together for a common outcome.

Temporal examination of adult food insecurity amongst Canadian families managing food allergy.

BACKGROUND: Pediatric food allergy is associated with excess familial food costs compared to families without allergy. Since the start of the COVID-19 pandemic, food prices have increased substantially. OBJECTIVE: To understand the temporal pattern of food insecurity amongst Canadian families with food allergy from the year prior to the pandemic, through May 2022. METHODS: Using data collected electronically from families reporting food allergy using a validated food security questionnaire, we estimated food insecurity, including categories of food insecurity (marginal, moderate, secure) in the year prior to the pandemic (2019; Wave 1), and the first (2020; Wave 2) and second years of the pandemic (2022; Wave 3). RESULTS: Participants in all waves were commonly in 2 + adult, 2 child households. Less than half of participants (Waves 1-3: 45.7%, 31.0%, and 22.9%, respectively) reported household incomes below the median Canadian. Common allergies were milk, eggs, peanuts and tree nuts. In Wave 1, 22.9% of families reported food insecurity; corresponding numbers at Waves 2 and 3 were 30.6% and 74.4%, respectively, representing an overall increase of 225.6%, including notable increases in severe food insecurity. CONCLUSION: Canadian families with pediatric food allergy report higher rates of food insecurity compared to the general Canadian population, especially during the pandemic.

A review of food allergy-related costs with consideration to clinical and demographic factors.

PURPOSE OF REVIEW: To provide an overview of the magnitude and sources of food allergy-related costs, with a particular emphasis on the recent literature. We also aim to identify clinical and demographic factors associated with differences in food allergy-related costs. RECENT FINDINGS: Recent research has expanded upon previous studies by making greater use of administrative health data and other large sample designs to provide more robust estimates of the financial burden of food allergy on individuals and the healthcare system. These studies shed new light on the role of allergic comorbidities in driving costs, and also on the high costs of acute food allergy care. Although research is still largely limited to a small group of high-income countries, new research from Canada and Australia suggests that the high costs of food allergy extend beyond the United States and Europe. Unfortunately, as a result of these costs, newly emerging research also suggests that individuals managing food allergy, may be left at greater risk of food insecurity. SUMMARY: Findings underscore the importance of continued investment in efforts aimed at reducing the frequency and severity of reactions, as well as programs designed towards helping offset individual/household level costs.

Prehospital epinephrine administration for treating anaphylaxis among those with comorbid asthma: A scoping review.

BACKGROUND: Prompt and correct use of epinephrine for treating anaphylaxis is considered essential in reducing the risk of fatal outcomes from anaphylaxis. Nevertheless, prehospital use of epinephrine remains low. Although asthma is a common comorbidity in individuals experiencing severe allergic reactions, little attention has been given to whether asthma functions as a predictor of prehospital epinephrine administration. OBJECTIVE: To perform a scoping review of the extant literature on using epinephrine to manage anaphylaxis in patients with comorbid asthma before presenting to the emergency department. METHODS: Per Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review guidelines, peer-reviewed articles published in English or French were searched for within the Medline, Cumulative Index to Nursing and Allied Health Literature, and Embase databases between June 11 and June 18, 2021. We excluded studies that did not contain primary data. RESULTS: The literature search yielded 1022 articles that were screened at the title and abstract level by 2 independent reviewers. Of these, 90 (8.8%) advanced to full-text review, and ultimately, 8 studies (0.8% of all articles; 8.9% of full-text articles) were included in the analysis. Overall, the association between comorbid asthma and epinephrine use in the prehospital setting for managing anaphylaxis was inconsistently reported in the literature. Three studies reported a positive association, whereas 2 others suggested a link, but their results were no longer significant when controlling for other study variables. Three studies described no significant association. CONCLUSION: Although asthma is frequently comorbid in individuals experiencing anaphylaxis, the association between comorbid asthma and prehospital epinephrine treatment rates remains an understudied area of patient care.

Vaccine confidence among those living with allergy during the COVID pandemic (ACCORD): A scoping review.

Background: Reports of allergic reactions to coronavirus disease 2019 (COVID-19) vaccines, coupled with an "infodemic" of misinformation, carry the potential to undermine confidence in the COVID-19 vaccines. However, no attempts have been made to comprehensively synthesize the literature on how allergic disease and fear of allergic reactions to the vaccines contribute to hesitancy. Objectives: Our aim was to review the academic and gray literature on COVID-19 vaccine hesitancy and allergic reactions. Methods: We searched 4 databases (CINAHL, PsycINFO, MEDLINE, and Embase) using a search strategy developed by content and methodologic experts. No restrictions were applied regarding COVID-19 vaccine type, country of study, or patient age. Eligible articles were restricted to 10 languages. Results: Of the 1385 unique records retrieved from our search, 60 articles (4.3%) were included. Allergic reactions to the COVID-19 vaccine were rare but slightly more common in individuals with a history of allergic disease. A fifth of the studies (13 of 60 [22%]) discussed vaccine hesitancy due to possibility of an allergic reaction. Additionally, the present review identified research on details of vaccine-related anaphylaxis (eg, a mean and median [excluding clinical trial data] of 12.4 and 5 cases per million doses, respectively) and allergic reactions (eg, a mean and median [excluding clinical trial data] of 489 and 528 cases per million doses, respectively). Conclusion: COVID-19 vaccine acceptance among individuals living with allergy and among those with no history of allergic disease may be affected by fear of an allergic reaction. Despite the low incidence of allergic reactions to the COVID-19 vaccine, fear of such reactions is one of the most commonly cited concerns reported in the literature.

Associations between food allergy, country of residence, and healthcare access.

BACKGROUND: To date, little consideration has been given to access to allergy-related care, despite the fact that food allergy affects a considerable proportion of children. As such, the current study aimed to describe access to food allergy-related services in Canada and the United States (US). METHODS: Participants were recruited via social media from March-July 2021 and were asked to complete an online survey focused on food allergy-related medical care. Participants were Canadian and US residents who live with a child < 18 years old, with ≥ 1 food allergy. A series of logistic regressions were used to assess the associations between country of residence and type of allergy testing utilized during diagnosis. RESULTS: Fifty-nine participants were included in the analysis (Canadian: 32/59; 54.2%; US residents: 27/59; 45.8%). Relative to Canadian participants, US respondents were less likely to be diagnosed using an oral food challenge (OFC; OR 0.16; 95% CI 0.04; 0.75: p < 0.05). Compared to children diagnosed by age 2 years, those diagnosed at age 3 years and older were less likely to have been diagnosed using an OFC (OR 0.12; 95% CI 0.01; 1.01; p = 0.05). CONCLUSIONS: Access to food allergy-related services, varies between Canada and the US. We speculate that this variation may reflect differences in clinical practice and types of insurance coverage. Findings also underscore the need for more research centered on food allergy-related health care, specifically diagnostic testing, among larger and more diverse samples.

Children's Perspectives on Food Allergy in Schools: A Qualitative Study.

Approximately 7% of children live with food allergy, a condition that requires dietary avoidance to prevent an allergic reaction. In this qualitative study, we aimed to understand food allergy-related experiences, beliefs and learning preferences among children with and without food allergies, to inform a school-based, food allergy education program. Data were analysed thematically. We virtually interviewed children in Kindergarten-Grade 8 in Manitoba, Canada, with (n = 7) and without (n = 9) parent-reported, physician-diagnosed food allergies. We identified three themes: Naive reliance on peers and school staff to assist with food allergy management; Limited food allergy knowledge; and, Recommended food allergy curricula: complementary perspective. Our findings will help inform the development of a school-based, food allergy education program, with a long-term goal of minimizing food allergy-related worries and optimizing safety for children with food allergy. Ongoing, school-based food allergy education is needed.

vACcine COnfidence amongst those living with alleRgy during the COVID pandemic (ACCORD): a scoping review protocol.

BACKGROUND: Reports of allergic reactions to the COVID-19 vaccines have been documented, which may also contribute to hesitancy. Despite the low likelihood that the COVID-19 vaccine will trigger an allergic reaction, we and others have reported that families with allergy remain vaccine hesitant due to concerns of COVID-19-vaccine-triggered anaphylaxis. OBJECTIVE: To present our scoping review protocol, that will inform a forthcoming living scoping review in which we will investigate the peer-reviewed and grey literature on COVID-19 vaccine hesitancy and allergic disease and/or allergic reactions following a COVID-19 vaccine. METHODS: Informed by Arksey and O'Malley framework for methodological review, we have developed a search strategy with content and methodological experts, and which has undergone Peer Review of Electronic Search Strategies review. A search of four scientific databases, as well as gray literature, will be performed without restriction to articles by type of COVID-19 vaccine, or country of study, and will include publications in the ten languages our team can handle. Bi-monthly search alerts based on the search strategy will be generated. RESULTS: The first search will result in a stand alone peer reviewed scoping review. Bi-monthly updates will be posted on a pre-print server. Depending on the volume of literature, these updates will be synthesized and submitted for peer-review at 6 and/or 12 months. CONCLUSION: COVID-19 vaccine hesitancy amongst individuals with allergy persists, despite very low risk of serious adverse reactions. Our living scoping review, which includes multiple forms of knowledge translation, will be a rigorous way to address hesitancy.

Changes in food-related costs during the COVID-19 pandemic among families managing food allergy.

Background: The COVID-19 pandemic has affected the supply, cost, and demand for certain foods, but it is not clear how these changes have affected food-allergic households. Objective: To describe the changes in food-related costs that have followed COVID-19, as reported by higher- and lower-income households with a food-allergic member. Methods: Between May 1-June 30, 2020, Canadian households, with at least one food-allergic member, completed an online survey on food shopping and preparation habits before and during the COVID-19 pandemic. The sample was divided into binary groups, either higher or lower than the sample median income. Data were analyzed using descriptive statistics and multiple regression. Results: The sample was comprised of 102 participants (i.e., 51/ income group). The three most common food allergies amongst both groups were peanuts, tree nuts and milk. Since the start of the pandemic, both groups reported greater monthly direct grocery costs, although costs amongst the higher-income group were twice as high as the lower-income group ($212.86 vs. $98.89, respectively). Indirect food preparation costs were similarly elevated. Higher-income households with food procurement difficulties reported increased indirect shopping costs following the outbreak of COVID-19, whereas those without such difficulties reported decreased costs. Lower-income households with allergies to milk, wheat, or eggs (i.e., staple allergy) experienced a larger change in indirect food preparation costs following the outbreak of COVID-19 relative to those with other food allergies ($244.58 vs. -$20.28, respectively; p = 0.03). Conclusion: Both higher and lower income households with food allergy reported greater direct food costs and indirect food preparation costs following the COVID-19. Households with staple allergy and those with difficulties finding their typical food items were particularly affected.

The Economic Burden of Food Allergy: What We Know and What We Need to Learn.

Purpose of Review: Food allergy management and treatment require dietary modification, are associated with significant burdens, and affect food choices and behaviours. Emerging therapies, such as oral immunotherapy (OIT), provide a glimmer of hope for those living with the condition. Some burdens have received substantial focus, whereas many knowledge gaps on the significance of other impacts, including economic burden, remain. Recent Findings: Evidence from many countries, but disproportionately from the United States, supports that food allergy carries significant healthcare and societal costs. Early introduction for the prevention of food allergies is theoretically cost-effective, but remains largely undescribed. Unique considerations, such as those to cow's milk protein allergy, which affects a substantial proportion of infants, and adrenaline autoinjectors, which have a high cost-per-use, require a balance between cost-effectiveness to the healthcare system and adverse outcomes. Household costs have largely been explored in two countries, but owing to different healthcare structures and costs of living, comparisons are difficult, as are generalisations to other countries. Stock epinephrine in schools may present a cost-effective strategy, particularly in economically disadvantaged areas. Costs relating to OIT must be examined within both immediate benefits, such as protection from anaphylaxis, and long-term benefits, such as sustained unresponsiveness. Summary: Although the absolute costs differ by region/country and type of food allergy, a consistent pattern persists: food allergy is a costly condition, to those who live with it, and the multiple stakeholders with which they interact.
