- Background: Allergic rhinitis (AR) management has changed in recent years following the switch from the concept of disease severity to the concept of disease control, publication of the AR clinical decision support system (CDSS) and development of mobile health (m-health) tools for patients (eg Allergy Diary). The Allergy Diary Companion app for healthcare providers is currently being developed and will be launched in 2018. It incorporates the AR CDSS to provide evidence-based treatment recommendations, linking all key stakeholders in AR management.Objective: To produce an electronic version of the AR CDSS (e-CDSS) for incorporation into the Allergy Diary Companion, to describe the app interfaces used to collect information necessary to inform the e-CDSS and to summarize some key features of the Allergy Diary Companion.Methods: The steps involved in producing the e-CDSS and incorporating it into the Allergy Diary Companion were (a) generation of treatment management scenarios; (b) expert consensus on treatment recommendations; (c) generation of electronic decisional algorithms to describe all AR CDSS scenarios; (d) digitization of these algorithms to form the e-CDSS; and (e) embedding the e-CDSS into the app to permit easy user e-CDSS interfacing.Results: Key experts in the AR field agreed on the AR CDSS approach to AR management and on specific treatment recommendations provided by Allergy Diary Companion. Based on this consensus, decision processes were developed and programmed into the Allergy Diary Companion using Titanium Appcelerator (JavaScript) for IOS tablets. To our knowledge, this is the first time the development of any m-health tool has been described in this transparent and detailed way, providing confidence, not only in the app, but also in the provided management recommendations.Conclusion: The Allergy Diary Companion for providers provides guideline and expert-endorsed AR management recommendations.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pulmonary hypertension (PH) is a progressive disorder of the pulmonary circulation,associated with diverse medical conditions. Exercise limitation is the most prominent symptom inPH. Exercise capacity, commonly assessed through a six-minute walk test (6MWT), correlates withboth functional status and survival in PH. Few studies have analysed the relation betweenrespiratory function and exercise limitation. Therefore, we investigated the relationship betweenresting pulmonary function, exercise capacity, and exertional desaturation, assessed through the6MWT, in unselected PH patients.Methods: Fifty consecutive patients with PH diagnosis, referred for pulmonary function testing(lung volume, spirometry, and diffusing capacity for carbon monoxide (DLCO)) and 6MWT, wererecruited at Molinette University Hospital, Turin.Results: The majority of the patients (54%) had PH due to left heart disease. Airway obstruction(FEV1/VC-ratio < 0.7) was found in 46% of the patients and they performed significantly worse inthe 6MWT than unobstructed patients (307 m vs. 377 m). Patients with PH due to left heartdisease also performed significantly poorer 6MWT when airway obstruction was present (305 mvs. 389 m). Twenty-two patients (44%) presented exertional desaturation upon 6MWT. LowerDLCO divided by the alveolar volume (DLCO/VA), FEV1/VC-ratios and resting PaO2-values weresignificantly correlated with exertional desaturation after adjustments for age, sex, BMI, andsmoking habits. DLCO/VA was the main determinant of exertional desaturation in a stepwiseregression model.Conclusions: Spirometric parameters of airway obstruction were related to walk distance andexercise-induced desaturation in PH patients. This suggests a place for spirometry in clinicalmonitoring of PH patients.

- Background: Chronic rhinosinusitis (CRS) has been reported to be associated with increased values of exhaled nitric oxide (ENO), which could not be entirely explained by the association between CRS and asthma. The aim of this study was to investigate the variables associated with increased ENO in patients with CRS. Methods: This was a prospective cross-sectional descriptive study of 93 consecutive patients with CRS. The effect on ENO of age, gender, atopy, asthma, respiratory symptoms without bronchial hyperresponsiveness (BHR), and nasal polyps was evaluated by multiple regression analysis. Results: Nasal polyps (P=.01), asthma (P<.001), and respiratory symptoms without BHR (P=.01) were the only independent variables associated with increased ENO. The prevalence of asthma was significantly higher in subjects with nasal polyps (61% vs 29.4%), P=.005, whereas the prevalence of respiratory symptoms without BHR was higher in those without nasal polyps (44.1% vs 15.3%, P=.003). Respiratory symptoms without BHR were associated with significantly higher ENO and prevalence of sputum eosinophilia (eosinophils>3%) in patients with nasal polyps compared with those without nasal polyps (68.2 vs 24.0 ppb, P=.001; 60% vs 8.3%, P=.03, respectively). Conclusions: The presence of nasal polyps in patients with CRS was associated with increased asthma prevalence as well as increased ENO levels. Respiratory symptoms without BHR were associated with eosinophilic airway inflammation and increased ENO only in patients with nasal polyps. These findings suggest important clinical and biologic differences between the two types of CRS, with and without nasal polyps.

- Inducible laryngeal obstruction (ILO) describes an inappropriate, transient, reversible narrowing of the larynx in response to external triggers. ILO is an important cause of a variety of respiratory symptoms and can mimic asthma. Current understanding of ILO has been hampered by imprecise nomenclature and variable approaches to assessment and management. A task force of the European Respiratory Society (ERS) and European Laryngological Society (ELS) was thus set up to address this, and to identify research priorities. A literature search identified relevant articles published until June 2016, using all identifiable terms for ILO, although including only articles using laryngoscopy. In total, 172 out of 252 articles met the inclusion criteria, summarised in sections on diagnostic approach, aetiology, comorbidities, epidemiology and treatment. The consensus taxonomy published by ERS, ELS and the American College of Chest Physicians (ACCP) in 2015 is used throughout this statement. We highlight the high prevalence of ILO and the clinical impact for those affected. Despite recent advances, most aspects of this condition unfortunately remain incompletely understood, precluding firm guidance. Specifically, validated diagnostic and treatment algorithms are yet to be established, and no randomised control studies were identified in this search; hence we also make recommendations for future research.

- Background: Acute exacerbations of COPD (AECOPD) are common and strongly influence disease severity and relative healthcare costs. Vitamin D deficiency is frequent among COPD patients and its contributory role in disease exacerbations is widely debated. Our aim was to assess the relationship of serum vitamin D levels with COPD severity and AECOPD. Methods: Serum vitamin D (25-hydroxyvitamin D) levels were measured in 97 COPD patients and related to lung function, comorbidities, FEV1 decline, AECOPD and hospital admission during the previous year. Results: Most patients (96%) had vitamin D deficiency, which was severe in 35 (36%). No significant relationship was found between vitamin D and FEV1 or annual FEV1 decline. No difference between patients with and without severe vitamin D deficiency was found in age, gender, BMI, smoking history, lung function, and comorbidities, apart from osteoporosis (60.9% in severe deficiency vs 22.7%, p = 0.001). In multiple logistic regression models, severe deficiency was independently associated with AECOPD [adjusted odds ratios (aOR) of 30.5 (95% CI 5.55, 168), p < 0.001] and hospitalization [aOR 3.83 (95% CI 1.29, 11.4), p = 0.02]. The odds ratio of being a frequent exacerbator if having severe vitamin D deficiency was 18.1 (95% CI 4.98, 65.8) (p < 0.001), while that of hospitalization was 4.57 (95% CI 1.83, 11.4) (p = 0.001). Conclusions: In COPD patients severe vitamin D deficiency was related to more frequent disease exacerbations and hospitalization during the year previous to the measurement of vitamin D. This association was independent of patients' characteristics and comorbidities.

- Background: Exhaled nitric oxide (NO), commonly accepted marker of airways inflammation, may be generated both by specific enzymes, NO synthases, as well as by nonenzymatic reduction in its metabolites. During asthma exacerbations, owing to lower airways pH, it has been reported that nitrite reduction may contribute to the increase in exhaled NO. Allergen exposure, an important cause of asthma exacerbations, is also known to increase exhaled NO. Design To investigate whether cat allergen exposure of cat-sensitized asthmatics leads to airway acidification, which could explain the expected increase in exhaled NO. Twelve nonsmoking, cat-sensitized patients (nine women) aged 33·5 (22-54) years with mild intermittent asthma performed a cat allergen challenge. Exhaled NO at 50-200mLs-1, nasal NO, exhaled breath condensate (EBC) pH, nitrite and nitrate were measured before, 8 and 24h after allergen challenge. Results A significant increase in FENO 50 was observed 24h after allergen challenge compared to baseline: 110ppb (34, 143) vs. 60ppb (19, 122), P=0·006. This was mainly explained by an increase in bronchial NO flux (P=0·02), while no changes in EBC pH were observed (P=0·35). Conclusions: Allergen exposure is not associated with airways acidification, implying that the observed increase in exhaled NO is probably because of enzymatic NO production.
