Background: There are few studies which analyse the characteristics of allergic respiratory disease according to profiles of sensitisation to different allergens. This study describes the clinical features and therapeutic approaches, according to the sensitisation profile to relevant aeroallergens, in a sample of adult patients with a first-time diagnosis of respiratory allergy (rhinitis and/or asthma). Methods: 1287 patients, enrolled consecutively in the spring of 2010 by 200 allergy specialists, were classified into four groups according to sensitisation to significant allergens in each geographical area (grass pollen, olive pollen, grass and olive pollen, house dust mites). Information was obtained on demographics, diagnostic procedures used, treatments prescribed, clinical characteristics of the rhinitis, and severity and control of asthma. Results: Of the patients, 58.6% had rhinitis only and 38.7% had both rhinitis and asthma. Patients with more severe rhinitis had more severe and poorer controlled asthma. Sensitisation to different allergens was not associated with significant differences in severity and control of asthma, but patients with house dust mite allergy presented persistent rhinitis more frequently. Allergy to grass pollen was significantly associated with food allergies. Differences were observed in the frequency of prescription of immunotherapy and antileukotrienes in patients allergic to house dust mites and of topical corticosteroids in patients with pollen allergy. Conclusions: It was observed in this study that in respiratory allergy disease, there are clinical differences as well as differences in diagnostic procedure and therapeutic attitudes, depending on the clinically relevant allergen. © 2012 SEICAP.

Background Current phenotyping of chronic rhinosinusitis (CRS) into chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP) might not adequately reflect the pathophysiologic diversity within patients with CRS. Objective We sought to identify inflammatory endotypes of CRS. Therefore we aimed to cluster patients with CRS based solely on immune markers in a phenotype-free approach. Secondarily, we aimed to match clusters to phenotypes. Methods In this multicenter case-control study patients with CRS and control subjects underwent surgery, and tissue was analyzed for IL-5, IFN-γ, IL-17A, TNF-α, IL-22, IL-1β, IL-6, IL-8, eosinophilic cationic protein, myeloperoxidase, TGF-β1, IgE, Staphylococcus aureus enterotoxin-specific IgE, and albumin. We used partition-based clustering. Results Clustering of 173 cases resulted in 10 clusters, of which 4 clusters with low or undetectable IL-5, eosinophilic cationic protein, IgE, and albumin concentrations, and 6 clusters with high concentrations of those markers. The group of IL-5-negative clusters, 3 clusters clinically resembled a predominant chronic rhinosinusitis without nasal polyps (CRSsNP) phenotype without increased asthma prevalence, and 1 cluster had a TH17 profile and had mixed CRSsNP/CRSwNP. The IL-5-positive clusters were divided into a group with moderate IL-5 concentrations, a mixed CRSsNP/CRSwNP and increased asthma phenotype, and a group with high IL-5 levels, an almost exclusive nasal polyp phenotype with strongly increased asthma prevalence. In the latter group, 2 clusters demonstrated the highest concentrations of IgE and asthma prevalence, with all samples expressing Staphylococcus aureus enterotoxin-specific IgE. Conclusion Distinct CRS clusters with diverse inflammatory mechanisms largely correlated with phenotypes and further differentiated them and provided a more accurate description of the inflammatory mechanisms involved than phenotype information only. © 2016 American Academy of Allergy, Asthma & Immunology.

Objective: We aimed to analyze health-related quality of life (HRQOL) in adults with newly diagnosed respiratory allergy according to the sensitization profile for relevant aeroallergens in their usual area of residence. Methods: We performed a cross-sectional, epidemiological, observational, descriptive, multicenter study in allergy clinics in Spain. The sample comprised adults diagnosed with rhinitis, asthma, or both caused by significant allergens in their residential area (olive and/or grass pollen or house dust mite). Allergic rhinitis was classified according to the Allergic Rhinitis and its Impact on Asthma guidelines; asthma was classified according to the Guía Española para el Manejo del Asma (Spanish Guideline on the Management of Asthma). HRQOL was studied according to the ESPRINT-15 questionnaire and Mini Asthma Quality of Life Questionnaire. Control of asthma was measured using the Asthma Control Questionnaire 5. Results: We studied 1437 patients. Rhinitis was the most common respiratory disease. The HRQOL of rhinitis patients was lower in those sensitized to olive pollen only and in those with combined sensitization to olive and grass pollens. HRQOL associated with rhinitis was worse in patients diagnosed with both rhinitis and asthma than in patients diagnosed with rhinitis only. Asthma patients sensitized to olive pollen or olive and grass pollens had worse HRQOL. Conclusions: In our study population, the HRQOL of patients with respiratory allergies varied with the allergen responsible for symptoms. In patients with rhinitis, the presence of asthma significantly worsened rhinitis-associated HRQOL. © 2013 Esmon Publicidad. Source

Allergic rhinitis (AR) is a major health problem with high and ever-increasing prevalence worldwide. At least one-fifth of adults in industrialized countries are estimated to have AR, defined as nasal and eye symptoms that are sufficiently severe to have a substantial negative impact on the quality of life (QoL). The former classification of AR comprised seasonal AR (SAR) and perennial AR (PAR), which did not adequately reflect the presentation and clinical course of the disease. The Allergic Rhinitis and its Impact on Asthma (ARIA) classification is based on the duration of symptoms and the disease severity. Both intermittent AR (IAR: symptoms ≤ 4 days/week or ≤ 4 consecutive weeks) and persistent AR (PER: symptoms > 4 days/week and > 4 consecutive weeks) may be mild, moderate, or severe based on the QOL impairment (sleep, daily activities/leisure, work productivity/school performance) and bothersome symptoms. Despite its disabling effects, AR remains a condition where affected individuals do not seek appropriate treatment, are undertreated and do not adhere well to treatment, which all lead to low disease control and high societal costs. The four pillars of AR treatment are allergen and pollutant avoidance, patient education, pharmacotherapy and allergen-specific immunotherapy. Oral antihistamines, together with intranasal corticosteroids and leucotriene antagonists, constitute important pharmacological options for the treatment of AR at all levels of severity. New second-generation antihistamines are H1-receptor antagonists with high efficacy (rapid onset of action for AR symptoms, sometimes even on nasal congestion, improvement of QoL and additional anti-allergic effects) and safety (low sedation rates). Although new antihistamines have been studied and approved for SAR and PAR, only some of them have been reported to show efficacy and safety for treatment of AR under the ARIA classification: levocetirizine (high efficacy) and rupatadine (dual antihistamine and anti-PAF effects) for PER, and desloratadine (high safety) for both IAR and PER. © 2012 Blackwell Publishing Ltd.

Leukotriene receptor antagonists, such as montelukast (MK), are currently used to treat rhinitis and asthma, but their anti-inflammatory role in eosinophil inflammation is not well understood. The aim of this study is to investigate the effect of MK on an in vitro model of upper-airway eosinophil inflammation by reducing pro-inflammatory cytokines from both nasal mucosa (NM) and polyp (NP) epithelial cells and reducing eosinophil survival primed by epithelial cell secretions. Epithelial cells were stimulated with fetal bovine serum (FBS) with/without MK for 24 hours, and cytokine concentrations in epithelial secretions were measured by ELISA. After incubating peripheral blood eosinophils with epithelial cell-conditioned media (ECM) with/without MK up to 3 days, eosinophil survival was assessed by Trypan blue dye exclusion. Results are expressed as mean ± SEM of cytokine concentration (% of control) or eosinophil survival (%). Epithelial cell stimulation increased GM-CSF, IL-6, IL-8, and sICAM-1 secretion in both NM and NP. MK had a significant inhibitory effect on FBS-induced GM-CSF, IL-6, and IL-8 secretion, but not sICAM-1, in both NM and NP. MK also showed an inhibitory effect (p<0.05) on ECM-induced eosinophil survival from both NM (from 10-5M to 10-7M, n=7) and NP (at 10-5M, n=7), after 3 days of incubation. These anti-inflammatory effects on epithelial cell cytokine secretion and on eosinophil survival suggest that montelukast may contribute to the reduction of eosinophilic inflammation in upper-airway inflammatory diseases such as rhinitis and nasal polyposis.
