ARIA digital anamorphosis: Digital transformation of health and care in airway diseases from research to practice.

Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed.

Allergic rhinitis.

Allergic rhinitis (AR) is caused by immunoglobulin E (IgE)-mediated reactions to inhaled allergens and is one of the most common chronic conditions globally. AR often co-occurs with asthma and conjunctivitis and is a global health problem causing major burden and disability worldwide. Risk factors include inhalant and occupational allergens, as well as genetic factors. AR impairs quality of life, affects social life, school and work, and is associated with substantial economic costs. The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative classified AR into intermittent or persistent and mild or moderate/severe. The diagnosis is based on the clinical history and, if needed in patients with uncontrolled rhinitis despite medications or with long-lasting symptoms, on skin tests or the presence of serum-specific IgE antibodies to allergens. The most frequently used pharmacological treatments include oral, intranasal or ocular H1-antihistamines, intranasal corticosteroids or a fixed combination of intranasal H1-antihistamines and corticosteroids. Allergen immunotherapy prescribed by a specialist using high-quality extracts in stratified patients is effective in patients with persistent symptoms. Real-world data obtained by mobile technology offer new insights into AR phenotypes and management. The outlook for AR includes a better understanding of novel multimorbid phenotypes, health technology assessment and patient-centred shared decision-making.

Rhinitis: adherence to treatment and new technologies.

PURPOSE OF REVIEW: Nonadherence to treatment is a major issue in approximately 50% of patients suffering from chronic diseases. The availability of new technologies could represent a possible way to improve patients' engagement and adherence in a real-life setting. Research and technology tools made available or in process of being made available to patients with allergic diseases and their physicians could potentially improve the management of these disease in daily life by improving adherence. In this review, we sought to outline many of the recent advances in these technological approaches. RECENT FINDINGS: Short Message Service (SMS) reminder, social networks, wearable devices, mobile applications (Apps), monitoring systems of inhaled device use, often presented as 'serious game' are changing the way of approaching to chronic disease, such as rhinitis, management. SUMMARY: Studies of the role played by various technologies in improving adherence to treatment in rhinitis are still limited as compared with other diseases such as asthma, but the results are encouraging. Further studies in this area may lead to the discovery of novel management approaches that is easy to be integrated in patients' daily life.

GA² LEN/EAACI pocket guide for allergen-specific immunotherapy for allergic rhinitis and asthma.

This pocket guide is the result of a consensus reached during several GA(2) LEN and EAACI meetings. The aim of the current pocket guide is to offer a comprehensive set of recommendations on the use of immunotherapy in allergic rhinoconjunctivitis and asthma in daily practice. This pocket guide is meant to give simple answers to the most frequent questions of practitioners in Europe, including 'practising allergists', general practitioners and any other physicians with special interest in allergen-specific immunotherapy (SIT). It is not a long or detailed scientific review of the topic. However, the recommendations in this pocket guide were compiled following an in-depth review of existing guidelines and publications, including the 1998 EAACI position paper, the 1998 WHO Position Paper on SIT and the 2001 Allergic Rhinitis and its Impact on Asthma (ARIA). It is also based on the ARIA update 2008 (prepared in collaboration with GA(2) LEN), the 'Sub-lingual Immunotherapy: WAO Position Paper 2009' (from the World Allergy Organisation) and the Methodology paper of ARIA. The recommendations cover patient selection, allergen extract to be used, route of administration of SIT (in particular, sublingual and subcutaneous immunotherapy), and necessary precautions to be followed in using SIT.

EAACI/GA(2)LEN/EDF/WAO guideline: definition, classification and diagnosis of urticaria.

This guideline, together with its sister guideline on the management of urticaria [Zuberbier T, Asero R, Bindslev-Jensen C, Canonica GW, Church MK, Giménez-Arnau AM et al. EAACI/GA(2)LEN/EDF/WAO Guideline: Management of urticaria. Allergy, 2009; 64:1427-1443] is the result of a consensus reached during a panel discussion at the 3rd International Consensus Meeting on Urticaria, Urticaria 2008, a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU-funded network of excellence, the Global Allergy and Asthma European Network (GA(2)LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO). Urticaria is a frequent disease. The life-time prevalence for any subtype of urticaria is approximately 20%. Chronic spontaneous urticaria and other chronic forms of urticaria do not only cause a decrease in quality of life, but also affect performance at work and school and, as such, are members of the group of severe allergic diseases. This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors, and pathomechanisms. In addition, it outlines evidence-based diagnostic approaches for different subtypes of urticaria. The correct management of urticaria, which is of paramount importance for patients, is very complex and is consequently covered in a separate guideline developed during the same consensus meeting. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS).

EAACI/GA(2)LEN/EDF/WAO guideline: management of urticaria.

This guideline, together with its sister guideline on the classification of urticaria (Zuberbier T, Asero R, Bindslev-Jensen C, Canonica GW, Church MK, Giménez-Arnau AM et al. EAACI/GA(2)LEN/EDF/WAO Guideline: definition, classification and diagnosis of urticaria. Allergy 2009;64: 1417-1426), is the result of a consensus reached during a panel discussion at the Third International Consensus Meeting on Urticaria, Urticaria 2008, a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU-funded network of excellence, the Global Allergy and Asthma European Network (GA(2)LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO). As members of the panel, the authors had prepared their suggestions regarding management of urticaria before the meeting. The draft of the guideline took into account all available evidence in the literature (including Medline and Embase searches and hand searches of abstracts at international allergy congresses in 2004-2008) and was based on the existing consensus reports of the first and the second symposia in 2000 and 2004. These suggestions were then discussed in detail among the panel members and with the over 200 international specialists of the meeting to achieve a consensus using a simple voting system where appropriate. Urticaria has a profound impact on the quality of life and effective treatment is, therefore, required. The recommended first line treatment is new generation, nonsedating H(1)-antihistamines. If standard dosing is not effective, increasing the dosage up to four-fold is recommended. For patients who do not respond to a four-fold increase in dosage of nonsedating H(1)-antihistamines, it is recommended that second-line therapies should be added to the antihistamine treatment. In the choice of second-line treatment, both their costs and risk/benefit profiles are most important to consider. Corticosteroids are not recommended for long-term treatment due to their unavoidable severe adverse effects. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS).

Levocetirizine improves health-related quality of life and health status in persistent allergic rhinitis.

BACKGROUND: Allergic rhinitis is a chronic respiratory disorder with a detrimental impact on health-related quality of life (HRQOL) and health status. Enhancement and maintenance of patient function and well-being are therefore considered as essential. OBJECTIVE: To determine whether long-term treatment with levocetirizine 5mg improves HRQOL and health status in persistent allergic rhinitis (PER) patients assessed with RQLQ and SF-36 scales over a 6-month period. METHODS: The Xyzal in PER Trial (XPERT) was a multi-center, double-blind, parallel-group study. A total of 551 patients were randomized to receive levocetirizine 5mg or placebo once daily for 6 months and assessed for symptoms, HRQOL (Rhinoconjunctivitis Quality of Life Questionnaire: RQLQ) and health status (SF-36). Sensitivity of the RQLQ and SF-36 to disease severity was tested to ensure their suitability for use in PER patients. Treatment effect was assessed by means of repeated measures analyses. RESULTS: Over the 6-month treatment period, levocetirizine showed statistically significant improvements over placebo in HRQOL (P < 0.001 for all RQLQ domains and overall scores) and health status (P < or = 0.004 for SF-36 physical and mental summary scores; P < 0.05 for all SF-36 scales). The relative improvement of levocetirizine over placebo exceeded the predefined clinically meaningful threshold of 30% for all RQLQ scores and the improvement from baseline was 3 times the established MID for RQLQ. CONCLUSION: The RQLQ and SF-36 could be used to measure HRQOL and health status in PER patients. Long-term treatment with levocetirizine provides sustained improvement of HRQOL and reduces disease burden in PER patients.

Direct and prolonged exposure to dogs does not influence the degree of skin prick test positivity to dog allergen.

BACKGROUND: The relationship between pet ownership and the risk of developing allergic sensitization to pet allergens is still controversial. We assessed the possible effect of direct exposure to dog allergen on skin reactivity in dog-sensitized patients. METHODS: We studied, in a case-control trial, 116 adults sensitized to dog allergens (55 with a dog at home for at least 10 years and 61 without it). The degree of response was assessed by skin prick test, performed in quadruplicate with three concentrations of allergenic extract: A (1:20 w/v), B (1:200 w/v) and C (1:2000 w/v). The mean diameter of each wheal was assessed using a visilog image analysis software. RESULTS: No significant difference between the two groups in the wheal diameters induced by the three concentrations of dog allergen could be demonstrated. CONCLUSION: The results of this study suggest that direct dog exposure in adults with respiratory allergy is not associated with greater cutaneous response to dog allergens, as compared to non exposed subjects.

Pollen mixtures used as health food may be a harmful source of allergens.

We describe herein one case of systemic anaphylaxis due to the ingestion of an undefined mixture of pollens, sold as a dietary supplement. The patient, who suffered from rhinoconjunctivitis due to grass pollen (with sensitization to several trees), had a severe episode of anaphylaxis immediately after eating this health food. The episode required emergency care. We attempted to study the pollen mixture responsible, but no pollen granules could be identified. We prepared a solid phase with the pollen mixture, and we observed a RAST positivity with the patient's serum and pools of sera containing specific IgE to trees. Furthermore, a RAST-inhibition assay of the patient's serum showed highly positive results with grasses, birch, alder and Compositae. Therefore, we concluded that the pollen mixture contained determinants capable of cross-reacting with the patient's IgE. This case report is evidence of the possible risks due to the use of undefined herbal products by allergic patients.
