- It is well recognized that atopic sensitization is an important risk factor for asthma, both in adults and in children. However, the role of allergy in severe asthma is still under debate. The term 'Severe Asthma' encompasses a highly heterogeneous group of patients who require treatment on steps 4-5 of GINA guidelines to prevent their asthma from becoming 'uncontrolled', or whose disease remains 'uncontrolled' despite this therapy. Epidemiological studies on emergency room visits and hospital admissions for asthma suggest the important role of allergy in asthma exacerbations. In addition, allergic asthma in childhood is often associated with severe asthma in adulthood. A strong association exists between asthma exacerbations and respiratory viral infections, and interaction between viruses and allergy further increases the risk of asthma exacerbations. Furthermore, fungal allergy has been shown to play an important role in severe asthma. Other contributing factors include smoking, pollution and work-related exposures. The 'Allergy and Asthma Severity' EAACI Task Force examined the current evidence and produced this position document on the role of allergy in severe asthma.

- Innate lymphoid cells (ILC) represent a group of lymphocytes that lack specific antigen receptors and are relatively rare as compared to adaptive lymphocytes. ILCs play important roles in allergic and nonallergic inflammatory diseases due to their location at barrier surfaces within the airways, gut, and skin, and they respond to cytokines produced by activated cells in their local environment. Innate lymphoid cells contribute to the immune response by the release of cytokines and other mediators, forming a link between innate and adaptive immunity. In recent years, these cells have been extensively characterized and their role in animal models of disease has been investigated. Data to translate the relevance of ILCs in human pathology, and the potential role of ILCs in diagnosis, as biomarkers and/or as future treatment targets are also emerging. This review, produced by a task force of the Immunology Section of the European Academy of Allergy and Clinical Immunology (EAACI), encompassing clinicians and researchers, highlights the role of ILCs in human allergic and nonallergic diseases in the airways, gastrointestinal tract, and skin, with a focus on new insights into clinical implications, therapeutic options, and future research opportunities.

- Chronic rhinosinusitis with nasal polyps (CRSwNP) often requires surgery, but recurrence even after surgery is common. Recurrence rates largely vary in literature and asthma seems to be a comorbid factor. Objective In this study, we aim to estimate disease recurrence during a long-term follow-up, together with the investigation of possible predicting and/or influencing parameters. Methods Out of 196 patients operated for CRSwNP between 01/2000 and 01/2006, 133 patients had a follow-up of at least 10 years and could be included. The inflammatory profile at surgery was determined on nasal tissue and sinonasal secretions, and included analysis of eosinophils, eosinophilic-rich mucus (ERM) typically containing Charcot-Leyden crystals (CLC), and fungal hyphae (FH). During follow-up, recurrence, received treatments and comorbidities were collected. Results Out of the 133 included patients, local eosinophilia was present in 81% and ERM in 60%. Recurrence during follow-up was observed in 62%, and was associated with local eosinophilia and ERM (both p < 0.001). Asthma was present in 28% at inclusion, and 17% developed asthma after surgery during follow-up. The presence of asthma, at inclusion as well as developed during follow-up, was significantly associated with recurrence of CRSwNP (p = 0.001 for group comparison). Conclusion Recurrence after CRSwNP surgery is common when a long-term follow-up is taken into account. ERM detected in sinonasal secretions at surgery seems to be a predictive factor for recurrence and need for revision surgery. Asthma is a frequently found comorbid factor in CRSwNP, develops even at higher age despite surgical treatment for CRSwNP, and is also associated with a higher recurrence rate. Sustained medical care after surgery is mandatory.

- Purpose of review There is a clear need for simple and reliable patient-reported outcome measures for chronic obstructive pulmonary disease (COPD) and asthma in daily practice. The purpose of this review is to facilitate the choice for clinicians of patient-reported outcomes which they can use in their daily practice. Recent findings More than 50 patient-reported outcome measures for asthma and COPD exist and clinicians are often left confused on which to use. Four tools (two for asthma and two for COPD) can be suggested based on validity/reliability, responsiveness, practicality and are particularly convenient in terms of time to measure. Summary On the basis of ample evidence, the COPD assessment test and the clinical COPD questionnaire for COPD and asthma control questionnaire and the asthma control test for asthma can be recommended for use in both primary care and other clinical settings. A simple guide figured as smiley faces has been designed to assist physicians to easily select the appropriate measure. With the current direction of thinking into treatable traits, targeted measures that evaluate the upper airways like the control of allergic rhinitis and asthma test may also be more used in the future.
