RESUMEN
Telehealth is an emerging approach that uses technology to provide healthcare remotely. Recent publications have outlined the importance of supporting the transition to self-management of adolescents with allergic conditions. However, no synthesis of the evidence base on the use and impact of telehealth interventions for this purpose has been conducted to date. This review achieves these aims, in addition to exploring the language use surrounding these interventions, and their implementation. Four databases were searched systematically. References were independently screened by two reviewers. Methodological quality was assessed using the Mixed Methods Appraisal Tool. A narrative synthesis was undertaken. Eighteen articles were included, reporting on 15 telehealth interventions. A total of 86% targeted adolescents with asthma. Mobile applications were the most common telehealth modality used, followed by video-conferencing, web-based, virtual reality and artificial intelligence. Five intervention content categories were identified; educational, monitoring, behavioural, psychosocial and healthcare navigational. Peer and/or healthcare professional interaction, gamification and tailoring may increase engagement. The studies showed positive effects of the interventions or no difference from active controls, in self-management outcomes such as knowledge, health outcomes such as quality-of-life, and economic outcomes such as healthcare utilization. The most common implementation outcomes reported were acceptability, appropriateness, feasibility and fidelity.

BACKGROUND: Complete avoidance of milk is the usual management for IgE-mediated cow's milk protein allergy (CMPA). A baked milk ladder is a method of dietary advancement therapy in IgE-mediated CMPA in Ireland, while in Spain, avoidance of milk awaiting natural tolerance acquisition through an oral food challenge (OFC) is employed. The aim of this study was to evaluate the use of dietary advancement therapy using a milk ladder compared with complete avoidance of milk for managing IgE-mediated CMPA. METHODS: This is a retrospective chart review of 371 pediatric patients from the population who have been treated for IgE-mediated CMPA between 2011 and 2020, with the milk ladder (Ireland) or complete avoidance followed by an OFC (Spain). The main outcome was the introduction of cow's milk. RESULTS: Milk ladder patients were 3.67 times more likely to succeed in comparison with milk avoidance (p < .001). Anaphylaxis during the treatment period occurred in 34 patients in the milk avoidance groups, while three patients in the milk ladder group experienced anaphylaxis due to accidental exposure to milk (p < .001). Failure to complete treatment was associated with a higher skin prick test in the milk avoidance group and a raised specific IgE in the milk ladder group. CONCLUSION: This is the first study that compares outcomes of dietary advancement therapy to complete avoidance for CMPA management, demonstrating that cow's milk can be successfully and safely reintroduced using dietary advancement therapy using a milk ladder.

The incidence of food allergies has risen around the globe, and experts have been exploring methods of preventing such allergies in young children to ease the burden of disease and reduce the morbidity and mortality caused by anaphylaxis to food allergens. Such preventative measures can be categorised as primary, secondary and tertiary prevention, which are discussed in detail in this review. Primary prevention is defined as the prevention of becoming sensitised towards specific allergens. The evidence suggests that avoiding common allergenic foods during pregnancy and breastfeeding is not protective against food allergies, and guidelines recommend weaning from 4 to 6 months of age, with recent studies supporting the early introduction of peanuts at 4 months to prevent peanut allergy. Secondary prevention targets patients who are already sensitised and aims to halt the progression of sensitisation, with evidence for high rates of success and safety in trials of early introduction to milk and peanuts using oral immunotherapy in sensitised infants. Tertiary allergy prevention focuses on reducing the risk of a patient having anaphylaxis, with oral immunotherapy being the most common method of promoting tolerance in allergic children. Several studies have demonstrated successful reintroduction for milk, egg and peanut; however, no such guidelines are recommended for other foods. Finally, dietary advancement therapy in the form of milk and egg ladders has been employed as a method of primary, secondary and tertiary prevention of allergies, particularly in Ireland, the UK and Canada.

BACKGROUND: Anaphylaxis is rising in prevalence among children. The current recommendations on the effective transition of anaphylaxis management to adolescents and young adults suggest preparation for the transition may be considered at 11-13 years of age in accordance with the patient's developmental stage. However, there has been limited research conducted on the perspective of caregivers regarding the transition of anaphylaxis management to their children. This study aims to determine the age caregivers feel it is appropriate to begin to teach their child to recognize anaphylaxis and use their adrenaline auto-injectors (AAI). METHODS: Caregivers of pediatric allergy patients who have been diagnosed with IgE-mediated food allergy and have an AAI prescription were contacted by phone and invited to complete a questionnaire about when they feel it is appropriate to begin to teach their child to recognize anaphylaxis and use their AAI. RESULTS: Of the 123 responses to the questionnaire received, 44.7% indicated that 9-11 years was the appropriate time for teaching their children to self-inject an AAI. History of severe anaphylaxis (94.3%), child's ability to describe reasons to inject adrenaline (87.8%), and demonstrate AAI use (82.1%) were "very important" readiness factors identified. Almost half of caregivers were "not confident" (8.94%) or "somewhat confident" (40.65%) in training their child to use AAI. Caregivers with higher household incomes more frequently identified themselves as the party responsible for training their children to use AAI (p = .04). CONCLUSION: Caregivers in this sample expressed different perspectives than the current guidelines regarding the timing to initiate the transition of anaphylaxis management to their child. Caregivers expressed suboptimal confidence in teaching their children to use AAI. Clinicians should be aware of the factors that may indicate caregivers' desire to initiate an earlier transition of anaphylaxis management to their child and ensure access to appropriate training, education and support is available.

BACKGROUND AND OBJECTIVE: The incidence of food allergy among children is on the rise. Children who are diagnosed with a food allergy receive long-term treatment for allergy management from allergy specialists, nurses and dieticians. This management may include the prescription of an adrenaline autoinjector (AAI) if the child is at risk of a severe allergic reaction (anaphylaxis). Therefore, it is important that parents of children with allergies are trained in the recognition of anaphylaxis and in the correct administration of an AAI. However, many parents are unable to correctly administer an AAI when assessed. The aim of this study is to review the current literature on caregiver's and paediatric patients' ability to use an AAI. METHODOLOGY: An electronic search to evaluate AAI technique in caregivers and children with food allergy was conducted. A total of 323 articles were screened in which 10 studies were reviewed. RESULTS: Seventy-eight percent of parents who had never been trained in the use of an AAI were unable to trigger it. In studies where paediatric patients' ability to use an AAI was assessed, a mean score of 7.78/9 was derived for AAI knowledge among adolescents. CONCLUSION: Caregivers and patient's ability to use an AAI was inconclusive, and further research should address the validation of an assessment tool for AAI use. A significant improvement in AAI use was found after an educational intervention. This highlights the need for improved education for allergic individuals and their caregivers, and further study should explore what are the best educational methods to meet these needs.

BACKGROUND: Anaphylaxis is a systemic, life-threatening reaction and its prevalence is rising amongst adolescents and young adults (AYA) with food allergies. The likelihood of fatal anaphylaxis is disproportionately high in this population. The effective management of anaphylaxis can be done by adhering to various food allergy-related self-care behaviours, namely avoidance of allergens, carriage and use of adrenaline auto-injectors (AAI). Unfortunately, compliance of AYA to these behaviours is believed to be suboptimal and the likely reason behind their increased rates of fatal anaphylaxis. METHODOLOGY: To evaluate the adherence to food allergy-related self-care behaviours amongst adolescents and young adults with anaphylaxis an electronic search was conducted utilizing PubMed, MEDLINE, and CINAHL plus to identify relevant studies. 175 article abstracts were screened, and 26 remained which were read in full to determine which best satisfied the inclusion and exclusion criteria. Ultimately, 10 articles were selected for this review. RESULTS: The compliance to food allergy-related self-care behaviours amongst AYA founded to be suboptimal. AAI design, peer influence, and emotional attitudes of AYA were found to be the most significant factors influencing AYA compliance to self-care behaviours. CONCLUSIONS: The adherence of AYA to food allergy-related self-care behaviours is suboptimal and evidence on the factors affecting AYA compliance has been largely contradictory. AAI design, peer influence, and emotional attitudes are significant factors influencing AYA adherence. Therefore, further research directed at these factors is imperative in facilitating the design of guidelines to maximize the adherence of AYA to food allergy-related self-care behaviours.

BACKGROUND: Anaphylaxis has been increasing in recent years, with common triggers in infants being milk and eggs. Currently, the mainstay of treatment for milk and/or egg allergy is strict avoidance. Recently, new therapies have emerged including stepwise introduction of allergens via a ladder approach. The suitability of infants for the ladders is debated. OBJECTIVE: This study aims to focus on the use of food ladders in children with anaphylaxis to egg or milk. METHODS: Retrospective review of pediatric patients diagnosed with immunoglobulin E-mediated milk and/or egg allergy between 2011 and 2021. Inclusion and exclusion criteria were applied. Anaphylaxis was defined as per the World Allergy Organization-amended criteria 2020. Data analysis utilized SPSS Version 28. RESULTS: We reviewed 1,552 patient charts, and excluded 1,094, leaving a total sample size of 458. Seventy infants had anaphylaxis at diagnosis (milk n = 36; egg n = 34). A range of 77.8% to 85.2% of infants with anaphylaxis successfully completed the ladder, 88.9% to 92.9% without anaphylaxis were successful. Children who successfully completed the ladder did so at similar rates. A range of 20.6% to 50% children presenting with anaphylaxis at diagnosis experienced allergic symptoms during treatment, compared with 17.3% to 40.7% without anaphylaxis. Reactions were mild, mostly cutaneous and not requiring medical attention. Patients experiencing allergic symptoms while on the ladder were less likely to successfully complete treatment. CONCLUSIONS: Milk and egg ladders are a safe and effective way of inducing tolerance in infants, including those with a history of anaphylaxis at diagnosis. There are no obvious predictors for who will experience allergic reactions while on the ladder; however, these children are less likely to complete the ladder, so parents should be educated in management of mild allergic reactions at home.

IgE-mediated cow's milk protein allergy (CMPA) is one of the most prevalent food allergies in early childhood. Though the cornerstone of management involves the strict avoidance of milk products while awaiting natural tolerance, research increasingly shows that the rates of resolution are slowing down. Therefore, there is a need to explore alternative pathways to promote tolerance to cow's milk in pediatric populations. This review aims to combine and appraise the scientific literature regarding the three CMPA management methods: avoidance, the milk ladder, and oral immunotherapy (OIT) and their outcomes in terms of efficacy, safety, and immunological effects. Cow's milk (CM) avoidance virtually protects against allergic reaction until natural tolerance occurs, with hypoallergenic substitutes available in the market, but accidental ingestion represents the main issue for this strategy. Introduction to baked milk using the milk ladder was designed, with most CMPA patients successfully completing the ladder. Similar to baked milk treatment, many OIT protocols also demonstrated decreased IgE and increased IgG4 levels post protocol, as well as a reduction in wheal size diameter. Though these strategies are shown to be safe and effective in CMPA, future clinical trials should compare the safety and effectiveness of these three management strategies.

BACKGROUND: In Spain, IgE-mediated cow's milk protein allergy (CMPA) affects approximately 0.69% of infants. Molecular diagnosis may be useful for monitoring natural spontaneous tolerance development in CMPA. The aim of this study was to retrospectively analyse a cohort of paediatric patients with IgE-mediated CMPA who were avoiding milk products awaiting natural tolerance and determine the relationship between disease persistence and major cow's milk allergens. METHODS: A retrospective chart review of 200 patients diagnosed with IgE-mediated CMPA between 2011 and 2020 was conducted. Patients strictly avoided milk products until an oral food challenge was performed. The main outcome was the introduction of liquid milk following a negative oral food challenge and its correlation with IgE and SPT measurements of milk components at diagnosis. Secondary outcomes included the rate of allergic reactions and anaphylaxis during the treatment period and its correlation with IgE and SPT measurements. RESULTS: Of the 200 charts analysed, 122 patients had a negative oral food challenge to milk (61.0%) (95% confidence interval (CI): 54.1-67.5) following a period of strict avoidance of milk. Higher levels of component-specific IgE, especially casein, were associated with failure in the oral food challenge (p = 0.02). Allergic reactions were experienced by 106 children (53%), of which 34 (17%; 95% CI: 12.4-22.8) had anaphylactic reactions. The risk of anaphylaxis was not predicted by raised IgE levels. CONCLUSIONS: While a large proportion of children acquired natural tolerance to cow's milk following a period of strict avoidance, IgE-mediated CMPA persisted in many children. Casein IgE levels at diagnosis were raised in those who failed to achieve natural tolerance. Allergic reactions to milk, including anaphylaxis, occurred commonly, but this was not predicted by raised IgE levels or SPT measurements.
RESUMEN
BACKGROUND: Atopic dermatitis (AD) at a young age often precedes the development of food allergies. Although AD affects millions of infants worldwide, prenatal and postnatal risk factors, and their association with the development of food allergies later on, are not fully elucidated. This study seeks to investigate AD epidemiology in infancy and its risk factors, examining early-life factors (both prenatal and postnatal) that could contribute to the later development of food allergies. METHODS: Between January 2019 and December 2019, 501 infants were included in this prospective cohort study. Longitudinal data collection was performed through maternal interviews, the first one conducted within three days after the delivery and the second within 24 to 36 months after the delivery, encompassing variables such as demographics, family history of atopy, maternal smoking, antibiotic use during pregnancy, the mode of delivery, breastfeeding history, food practices, and greenness exposure within 3 days from delivery, while they were still in the hospital. RESULTS: Maternal smoking during pregnancy (p = 0.001) and an older sibling atopy history (p = 0.03) was significantly linked to AD incidence. Cesarean section delivery (p = 0.04) was associated with a higher risk of food allergies in infants with AD. Having a garden at home correlated with a higher likelihood of AD (p = 0.01), and food elimination without medical guidance (p = 0.02) due to AD correlated with an elevated risk of food allergies. CONCLUSIONS: Encouraging timely allergenic food introduction while promoting dietary diversity, rich in plant-based foods, maternal smoking cessation, and professional dietary guidance may help minimize AD and food allergy risk. Future studies should address the role of greenness in the development of AD and food allergies.
