High PI3K/mTOR and low MAPK/JNK activity results in decreased apoptosis and autophagy in nasal polyposis

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 apoptotic index was used to demonstrate apoptotic cells.ResultsDecreased immunoreactivity of P38 MAPK (p

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]

Conclusions: Allergic rhinitis is common comorbidity of asthma that interrelated to asthma control. Identifiable allergens could be detected AR in asthma by SPT. Therefore, reduction of allergens exposure could become preventive approach for asthma patients with AR.

Conclusions: The severe asthmatic patients examined had a high prevalence of Aspergillus sensitization and of Aspergillus-associated diseases as ABPA (26%) and CPA (26%). It has to be demonstrated the benefit of an early recognition and treatment of these diseases on the course of asthma.

The incidence of chronic rhinosinusitis with nasal polyps has recently increased in Japan and other East Asian countries, and this disease is called eosinophilic chronic sinusitis (ECRS) in Japan. ECRS usually...

Aspirin-exacerbated respiratory disease (AERD) is a syndrome characterized by asthma that is often severe with progressive airway remodeling, the presence of eosinophilic chronic sinusitis with nasal polyp (CRSwNP) formation, and intolerance to aspirin and other non-selective cyclooxygenase 1 (COX-1) inhibitors.1 The prevalence of AERD in the general population is 1% which increases to 7% amongst those with asthma. In the most severe cases, ingestion of aspirin can trigger systemic reactions and even death.

AbstractPurpose of ReviewStaphylococcus aureus (S. aureus) is correlated with the development of persistent severe inflammatory disease of the upper airway including chronic rhinosinusitis with nasal polyps (CRSwNP). The presence ofS. aureus is associated with atopic disease including allergic rhinitis and atopic dermatitis and is associated with poor outcomes.Recent FindingsSeveral different strains ofS. aureus generate different toxins and gene products that can account for organism pathogenicity.S. aureus bacteria and its antigens shape the bacterial and fungal microbiome and the mucosal niche which generates host respo...

We report a case of eosinophilic chronic rhinosinusitis (ECRS) associated with choroidal folds and ocular motility disorder. A 50-year-old male with rhinosinusitis and bronchial asthma presented with anorthopia of the lower visual field and ocular motility disorder of the left eye. Dilated fundus examination and optical coherence tomography (OCT) revealed wavy choroidal folds in the upper retina. An emergent computed tomography (CT) showed sinusitis, a partial defect of the superior wall of the orbit on the left side, and deformation of the left eye. Based on the clinical findings, the patient was diagnosed with sinusitis ...

CONCLUSION: Endotyping can allow for the identification of groups of patients with CRS with a high likelihood of successful treatment, such as patients with a moderate type 2 immune reaction or those with acquired immune deficiency. PMID: 30353741 [PubMed - as supplied by publisher]
