Practical guide to skin prick tests in allergy to aeroallergens. Allergy 2012; 67: 18-24. Abstract This pocket guide is the result of a consensus reached between members of the Global Allergy and Asthma European Network (GA2LEN) and Allergic Rhinitis and its Impact on Asthma (ARIA). The aim of the current pocket guide is to offer a comprehensive set of recommendations on the use of skin prick tests in allergic rhinitis-conjunctivitis and asthma in daily practice. This pocket guide is meant to give simple answers to the most frequent questions raised by practitioners in Europe, including 'practicing allergists', general practitioners and any other physicians with special interest in the management of allergic diseases. 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 1993 European Academy of Allergy and Clinical Immunology position paper, the 2001 ARIA document and the ARIA update 2008 (prepared in collaboration with GA2LEN). The recommendations cover skin test methodology and interpretation, allergen extracts to be used, as well as indications in a variety of settings including paediatrics and developing countries.

Specific immunotherapy (SIT) is one of the treatments for allergic rhinitis. However, for allergists, nonspecialists, regulators, payers, and patients, there remain gaps in understanding the evaluation of randomized controlled trials (RCTs). Although treating the same diseases, RCTs in SIT and pharmacotherapy should be considered separately for several reasons, as developed in this study. These include the severity and persistence of allergic rhinitis in the patients enrolled in the study, the problem of the placebo, allergen exposure (in particular pollen and mite), the analysis and reporting of the study, the level of symptoms of placebo-treated patients, the clinical relevance of the efficacy of SIT, the need for a validated combined symptom- medication score, the differences between children and adults and pharmacoeconomic analyses. This statement reviews issues raised by the interpretation of RCTs in sublingual immunotherapy. It is not possible to directly extrapolate the rules or parameters used in medication RCTs to SIT. It also provides some suggestions for the research that will be needed. Interestingly, some of the research questions can be approached with the available data obtained from large RCTs.

Development and implementation of guidelines in allergic rhinitis – an ARIA-GA2LEN paper. Allergy 2010; 65: 1212–1221. The links between asthma and rhinitis are well characterized. The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines stress the importance of these links and provide guidance for their prevention and treatment. Despite effective treatments being available, too few patients receive appropriate medical care for both diseases. Most patients with rhinitis and asthma consult primary care physicians and therefore these physicians are encouraged to understand and use ARIA guidelines. Patients should also be informed about these guidelines to raise their awareness of optimal care and increase control of the two related diseases. To apply these guidelines, clinicians and patients need to understand how and why the recommendations were made. The goal of the ARIA guidelines is to provide recommendations about the best management options for most patients in most situations. These recommendations should be based on the best available evidence. Making recommendations requires the assessment of the quality of available evidence, deciding on the balance between benefits and downsides, consideration of patients' values and preferences, and, if applicable, resource implications. Guidelines must be updated as new management options become available or important new evidence emerges. Transparent reporting of guidelines facilitates understanding and acceptance, but implementation strategies need to be improved. [ABSTRACT FROM AUTHOR]

Rationale: Several randomized, double-blind, placebo-controlled clinical trials have demonstrated the efficacy of mometasone furoate nasal spray (MFNS) in the treatment of allergic rhinitis (AR) thus allowing for a meta-analysis to determine the overall treatment effect. Methods: A comprehensive search of the MEDLINE, LILACS, SCOPUS, and the Cochrane Library databases up to 31 October, 2007 was carried out. Randomized, double-blind, placebo-controlled, clinical trials evaluating the efficacy of MFNS in patients with AR compared to placebo were included. Total nasal symptom scores (TNSS), individual nasal symptoms, total non-nasal symptom scores (TNNSS) and nasal airflow were analysed as the standardized mean difference (SMD). Meta-analysis was performed with the random or the fixed effect models depending on heterogeneity, by usingrevman 5 software. Data synthesis: Sixteen of the 113 identified articles met the inclusion criteria. For MFNS efficacy on TNSS, 2998 participants were analysed: 1534 received MFNS and 1464 placebo. Mometasone furoate nasal spray was associated with a significant reduction in TNSS (SMD −0.49, 95% CI: −0.60 to −0.38; P < 0.00001; I2 = 50.1%). A significant effect on SMD for nasal stuffiness/congestion (−0.41; 95% CI: −0.56 to −0.27), rhinorrhoea (−0.44; 95% CI: −0.66 to −0.21), sneezing (−0.40; 95% CI: −0.57 to −0.23) and nasal itching (−0.39; 95% CI: −0.53 to −0.25) was also demonstrated. Mometasone furoate nasal spray treated subjects also showed a significant reduction in TNNSS (−0.30; 95% CI: −0.43 to −0.18). The proportion of patients with adverse events was similar for MFNS and placebo (0.99; 95% CI: 0.81–1.20; P = 0.91). Conclusions: This meta-analysis provides a level Ia evidence for the efficacy of MFSN in the treatment of AR vs placebo. Adverse events frequency was similar in both groups. [ABSTRACT FROM AUTHOR]

The article presents information on allergic rhinitis and its impact on asthma (ARIA). It informs that allergic rhinitis is a symptomatic disorder of the nose which is induced when exposed to allergen by an immunoglobulin E-mediated inflammation of the membranes lining the nose. It is noted that allergic rhinitis is a global health problem and the World Health Organization in the ARIA workshop updated guidelines concerning the disorder.

Background: We describe the methodology for the 2008 update of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines. The methodology differs from the 2001 edition in several respects. The most prominent change is the application of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to compiling evidence, assessing the quality of evidence and grading of recommendations. Methods and results: Representatives of the GRADE working group joined the ARIA guideline panel to achieve these tasks. While most recommendations result from existing systematic reviews, systematic reviews were not always available and the panel compiled the best available evidence in evidence profiles without conducting actual reviews. The panel conducted two meetings and used the GRADE criteria to assess the quality of evidence (four categories of high, moderate, low and very low) and the strength of recommendation (strong and weak) based on weighing up the desirable and undesirable effects of management strategies, considering values and preferences influencing recommendations, and resource implications. The guideline panel has chosen the words ‘we recommend’– for strong recommendations and ‘we suggest’– for weak recommendations. Both categories indicate the best course of action for a given patient population, but their implementation, requires different considerations as we describe subsequently in this article. Conclusions: The 2008 update of the ARIA guidelines has become more evidence-based. Future iterations of the guidelines will further be improved by following the described processes even closer, such as ensuring availability of updated high quality systematic reviews for each question.

Background: The Global Asthma Physician and Patient (GAPP) Survey is the first global quantitative survey designed to uncover asthma attitudes and treatment practices among separate groups of physicians and patients, with the goal of identifying barriers to optimal management. Method: A total of 5582 physician and patient interviews were conducted globally online, by telephone and face-to-face. This paper highlights key global findings from the adult arm (3559 interviews) conducted in 16 countries. Results: Physician and patient responses were found to differ when respondents were asked the same set of questions. Perceptions of time spent on asthma education, the quality of physician–patient communications, awareness and experience of side effects and understanding and knowledge of treatment noncompliance were found to differ between these two sets of respondents. Conclusions: The GAPP Survey not only defines an unmet need in asthma treatment, but also reveals that there is a direct relationship between the quality of physician–patient communication, the level of treatment side effects and the extent of patient compliance. These survey findings highlight a clear need for improved patient-focused care in asthma. [ABSTRACT FROM AUTHOR]

Specific Immunotherapy for respiratory allergy is used since about one century and there is now solid documentation of its efficacy. Nevertheless, the methods and experimental designs used in clinical trials are quite heterogeneous and there is no unanimously accepted methodological standard. Many studies are planned with study designs that may not confirm the clinical value of SIT as an effective treatment to reduce disease severity. To ensure that patients are treated based on sound scientific evidence and to minimize the risk of misusing limited financial resources for scientific studies, the World Allergy Organization (WAO) convened a group of experts to provide guidelines for the methodology of future immunotherapy studies. This document summarizes the recommendations for study design, patients’ selection, appropriate outcomes and statistical treatment to be used in planning and performing clinical trials with specific immunotherapy.

The pharmacologic treatment of allergic rhinitis proposed by ARIA is an evidence-based and step-wise approach based on the classification of the symptoms. The ARIA workshop, held in December 1999, published a report in 2001 and new information has subsequently been published. The initial ARIA document lacked some important information on several issues. This document updates the ARIA sections on the pharmacologic and anti-IgE treatments of allergic rhinitis. Literature published between January 2000 and December 2004 has been included. Only a few studies assessing nasal and non-nasal symptoms are presented as these will be discussed in a separate document. [ABSTRACT FROM AUTHOR]

Chemokines are a superfamily of small cytokines with activities ranging from leukocyte traffick to hematopoiesis, angiogenesis, and tissue organogenesis. Secondary lymphoid-organ chemokine (SLC/CCL21) was originally reported as a chemokine constitutively expressed by stromal cells and high endothelial venules in secondary lymphoid tissues and endothelium of afferent lymphatics, directing CCR7+ cells. More recently, others and we have demonstrated that SLC/CCL21 is up-regulated in different skin inflammatory conditions. Thereafter, this molecule is much more than a constitutive chemokine, which could play a role in effector and regulatory immune functions. [ABSTRACT FROM AUTHOR]

Summary In the last few decades much insight has been gained on the pathogenesis and risk factors associated with atopic diseases (asthma, rhinitis and atopic dermatitis). In addition, there are very effective drugs to manage exaceabations and to control the appearance of symptoms. The prevalence of allergic diseases, particularly in western countries (mainly English-speaking ones), and also in Latin America and Western Europe, is very high. Even in those countries with lower prevalence (such as in Africa or Asia), this has been higher than expected. In countries where surveys have been made using the same protocol in different time periods, an upward trend in the prevalence of atopic diseases has been shown. The socio-economic impact of atopic diseases has become a public health problem and a rise in costs can be expected in correlation with the increased prevalence. The inception of atopic diseases is the consequence of genetic and environmental interactions and some changes in environment in the last few decades could partly explain this trend. The roles of infections, allergen exposure, dietary factors, among others, are being intensively studied. Nevertheless, the reason for the increasing prevalence of atopic diseases is still unknown. The primary prevention of atopic disorders emerges as an ideal way to stop the upward trend in the prevalence of allergy and asthma and different environmental factors can be targeted to ameliorate the ‘atopic epidemic’.

Seasonal allergic rhinitis (SAR) and asthma, which are frequently comorbid, share some common allergic pathogenic bases. Clinical manifestations of these disorders might therefore be viewed as local manifestations of a systemic inflammatory state. Not only do the onsets of allergic-rhinitis (AR) and asthma symptoms often coincide (within 1 year), but also nasal challenges with SAR allergens can induce airways hyperreactivity (AHR). Eosinophils, which are key effector cells in both SAR and asthma, cause AHR, tissue damage, and neuronal effects through secretion of toxic granule proteins, enzymes, and other mediators. The novel, nonsedating, histamine H[sub 1]-receptor antagonist, desloratadine, which exerts various favorable effects on the allergic cascade, significantly decreased SAR symptoms (e.g., nasal congestion) and diminished daily β2-agonist use and improved asthma symptoms, while maintaining pulmonary function, in patients with SAR-asthma who were treated with once-daily desloratadine regimens.
