Airway eosinophilia is a prominent feature of asthma and chronic rhinosinusitis (CRS), and the endothelium plays a key role in eosinophil trafficking. To date, microRNA-1 (miR-1) is the only microRNA known to be regulated in the lung endothelium in asthma models.

Abstract BACKGROUND: Common variable immunodeficiency (CVID) is a heterogeneous group of disorders, characterized by recurrent upper and lower respiratory tract infections and some non-infectious clinical complications. OBJECTIVE: The current study aimed to provide a detailed evaluation of respiratory presentations and complications in a cohort of Iranian patients with CVID. METHODS: The present retrospective cohort study was conducted on 245 CVID patients who were recorded at the Iranian primary immunodeficiency disorders registry network. Respiratory manifestations were evaluated by reviewing clinical ...

This article provides highlights of the clinically impactful original studies and reviews published in The Journal of Allergy and Clinical Immunology: In Practice in 2019 on the subjects of anaphylaxis, asthma, dermatitis, drug allergy, food allergy, immunodeficiency, immunotherapy, rhinitis/sinusitis, and urticaria/angioedema/mast cell disorders. Within each topic, practical aspects of diagnosis and management are emphasized. Treatments discussed include lifestyle modifications, allergen avoidance therapy, positive and negative effects of pharmacologic therapy, and various forms of immunologic and desensitization manageme...

In this report, we compared [1] pathways identified from network analysis using genes derived from published genome-wide family-based and association studies for otitis media, sinusitis, and lung phenotypes, to [2] pathways identified using differentially expressed genes from RNA-sequence data from lower airway, sinus, and middle ear tissues, in particular cholesteatoma tissue compared to middle ear mucosa. For otitis media, a large number of genes (n = 1,806) were identified as differentially expressed between cholesteatoma and middle ear mucosa, which in turn led to the identification of 68 pathways that are enriched in ...

In this study we aimed to investigate apoptotic (MAPK/JNK), anti-apoptotic (PI3K/mTOR) and autophagic (LC3) pathways which are related each other in the nasal polyposis tissues.MethodsTwenty patients with nasal polyps and fifteen patients going through an inferior turbinate reduction were included in this study. Patients with asthma, Samter triad and allergic fungal sinusitis were excluded from the study. The apoptotic and autophagic pathways were investigated in paraffin-embedded nasal tissue sections of 20 NP and 15 samples from inferior turbinate reduction by H&E and immunohistochemistry with h-score. TUNEL method with ...

Purpose of review Eosinophilic otitis media (EOM) is an intractable otitis media characterized by numerous eosinophils infiltrating the middle ear cavity, which is part of the upper airway. EOM shows a high rate of comorbidity with asthma. They are considered to have a ‘one airway, one disease’ relationship. Here, we summarize our current knowledge regarding the characteristics of EOM, EOM's relationship with asthma and the efficacy of optimal treatments for EOM. Recent findings The greater the severity of asthma, the more pronounced the development of EOM. Asthma control is usually inadequate in asthmatic...

Conclusion: Our large cohort study, which is the first to focus on the link between otitis media in childhood and immune-related inflammatory disorders later in life, does not confer a clear association. CSOM in childhood was strongly related to adult tinnitus and hearing loss, which was most frequently registered as sensorineural.

Conclusions: In IDEAL, one-fifth of patients with SA were controlled, based on symptoms. Uncontrolled, exacerbating SA was associated with specific comorbidities, frequent exacerbations, lower lung function, and compromised HRQoL, although inference from this analysis is limited by the selective cross-sectional nature of the cohort. Nonetheless, these data highlight the need for more effective precision treatments in this population. PMID: 31874051 [PubMed - as supplied by publisher]
