How to Measure Disease Activity, Impact, and Control in Patients with Recurrent Wheals, Angioedema, or Both.

Chronic spontaneous urticaria and chronic inducible urticaria are characterized by wheals, angioedema, or both, whereas other conditions such as hereditary angioedema present only with angioedema. The unpredictability of outbreaks, disfigurement, pruritus, and associated sleep and work disturbance can cause a significant impact on quality of life (QoL). Significant breakthroughs in the understanding of these conditions in recent years have led to the development of novel therapies. Assessment of patients with these conditions not only focuses on the clinical activity of the condition, but also on the impact on QoL and disease control with treatment. Patient-reported outcome measures, especially if sufficiently validated, give due prominence to the patient's perspective regarding disease impact and treatment outcomes. This article will review the tools readily available to assess activity, impact, and control in patients with recurrent wheals, angioedema, or both.

Parent perceptions in managing children with food allergy: An Australian perspective.

INTRODUCTION: Food allergy affects up to 10% of Australian children, and living with food allergic children can be challenging for parents. This study explored parental perceptions and knowledge as they navigate a new reality of keeping their child safe. METHODS: Parents of children with food allergies completed an online food allergy survey in 2015. Questions explored health knowledge, skills, and attitudes (KSAs) as well as quality of life (QoL) through the inclusion of the Food Allergy Quality of Life - Parental Burden instrument (FAQL-PB). Notification of the survey included advertisements to more than 700 randomly selected Australia-wide preschools, 44 allergy specialists, and Allergy & Anaphylaxis Australia. Responses were tabulated and analysed. RESULTS: Of the 400 participants who logged on, 357 commenced the survey and 318 finished. Questionnaire analysis showed that 44.1% of parents (n = 135) hesitated to use an adrenaline auto-injector and may be influenced by a classification system where symptom severity is not universally understood. While 79% would sign up to a national Anaphylaxis Registry, intention to participate in clinical trials using vaccines was disclosed by only 56%. Allergen labelling and community acceptance continue to be the most challenging aspects of managing a food allergy, and 50% of parents reported that food allergy played a role in choosing a preschool or primary school. Overall, quality of life for participants was influenced more by gender (male) and age of the child than where they lived - capital city or regional location; however, regional participants were more frustrated over lack of appreciation relating to the seriousness of food allergy (p = 0.010). CONCLUSION: Results highlight the need for educational strategies for both the food allergy community and public, particularly in regional areas, since there is a perceived lack of appreciation as to the seriousness of food allergy. Educational resources and relevant networks are required to support parents and caregivers in the management of children with food allergy.

Bullying in Australian children and adolescents with food allergies.

BACKGROUND: Food allergy is an increasing concern worldwide. The significant impact of food allergies on quality of life and bullying has been well described in international studies. No studies have yet investigated the occurrence of bullying in children and adolescents with food allergies in the Australian population. This study aimed to characterize and examine the frequency of bullying and describe those most responsible and the effects of the bullying on the victims. METHODS: Questionnaires were developed based on those used in previous studies and were distributed throughout paediatric allergy clinics. Children and adolescents aged 10-19 with food allergies were recruited to complete the questionnaire independently, whilst parents completed the questionnaire on behalf of their children aged 5-9 with food allergies. The data were tabulated and analysed using descriptive statistics. RESULTS: Ninety-three questionnaires were completed. Overall, 39 (42%) children experienced some form of bullying. This was higher in the older children and adolescent group, where 53% (18/34) were bullied. In addition, 23% (21/93) of the cohort were bullied or teased specifically because of their allergy. Food allergens had been used in the bullying in 24 cases, but no child reported being forced to eat foods to which they were allergic. Two adolescents experienced allergic reactions. CONCLUSIONS: This study highlights that those with food allergy are subject to a high degree of bullying. This risk of bullying for children with food allergy indicates a significant social problem that requires addressing to positively assist these children.

Anaphylaxis audit in a busy metropolitan Emergency Department: a review of real life management compared to best practice.

BACKGROUND: Deficiencies in anaphylaxis management in Emergency Departments is well recognised despite established guidelines for its treatment. OBJECTIVE: To identify deficiencies in the management of anaphylaxis in a busy metropolitan Emergency Department and determine if an education intervention could correct these. METHODS: Paediatric and adult admissions to the Emergency Department of a busy hospital were tracked over a 10-month period with a targeted educational program being instituted at 5 months. The electronic records were retrospectively reviewed looking for cases of anaphylaxis and milder forms of immediate type allergic reactions presenting with a combination of urticaria and nonairway threatening angioedema. Anaphylaxis presentation was graded using the Brown grading system. Use of all medication during resuscitation was documented. Observation period before discharge and referral to specialist unit for follow-up was noted. RESULTS: In the first 5 months, 38 patients fulfilled our criteria. Three had severe anaphylaxis, 13 had moderately severe anaphylaxis and 12 had urticaria and angioedema without anaphylaxis. Anaphylaxis was not always recognised or graded leading to inappropriate management with adrenaline often being withheld. Promethazine, usually given in parenteral form, was frequently administered. Observation time was often inadequate. Referral to an immunologist was not universally followed through. Following the educational intervention 58 patients fulfilled our criteria over the next 5 months. The appropriate use of adrenaline increased by 21% and the use of sedating antihistamines decreased by 16%, while the number of referrals to an immunologist increased by 24%. There was an 11% reduction in the number of patients who were observed for at least 4 hours. CONCLUSION: A number of deficiencies in the management of anaphylaxis presentations have been identified. Targeted educational activities aimed at the Emergency Department hospital staff may improve outcomes.

Food allergy and oral allergy or pollen-food syndrome.

PURPOSE OF REVIEW: This paper reviews current concepts in our understanding of oral allergy or pollen-food syndrome. As technology has improved, much more accurate profiling of food allergic individuals is now possible, resulting in more precise diagnosis, elucidation of cross reactivity patterns and more helpful prediction of risk of anaphylaxis. RECENT FINDINGS: The identification and characterization of various ubiquitous plant proteins have led to greater understanding of food cross reactive reactions. Newer diagnostic techniques utilizing purified and recombinant allergens are available for more precise diagnosis and clinical profiling of patients presenting with food allergy. SUMMARY: In-vitro screening of food allergic patients with large panels of allergens will change the accuracy of diagnosis resulting in better management. Allergens are now available for use in the allergist's office to improve diagnostic accuracy of skin tests in patients presenting with plant-food allergy. Knowledge of the specific sensitization of individual patients has consequences for both risk assessment and dietary management.
