Olfactory Bulb Volume and Function Recovery in Eosinophilic Chronic Rhinosinusitis. [PDF]

Laryngoscope
This study investigated perioperative changes in olfactory bulb volume (OBV) in patients with eosinophilic chronic rhinosinusitis using high‐resolution 3T MRI. Postoperative increases in OBV were associated with improvements in olfactory identification, suggesting a potential link between olfactory bulb structural plasticity and functional recovery ...

Impact of Chronic Rhinosinusitis with Nasal Polyposis on IL-12 and IL-8 [PDF]

Iranian Journal of Otorhinolaryngology, 2023
Introduction: The pathophysiology of Chronic Rhinosinusitis is coordinated by distinct inflammatory reactions in different individuals. Inflammatory environments with a predominance of Th2 lymphocytes tend also to be rich in eosinophils.

Increased CD69 expression on activated eosinophils in eosinophilic chronic rhinosinusitis correlates with clinical findings

Allergology International, 2020
Background: Eosinophilic chronic rhinosinusitis (ECRS) is a subtype of chronic rhinosinusitis associated with asthma. CD69 is an important marker of activation for eosinophils.

Eosinophilic granulomatosis with polyangiitis developed after dupilumab administration in patients with eosinophilic chronic rhinosinusitis and asthma: a case report

BMC Pulmonary Medicine, 2023
Background Eosinophilic granulomatosis with polyangiitis (EGPA) is a form of anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis characterized by eosinophil-rich granulomatous inflammation and small-to-medium vessel vasculitis associated ...

Role of P2X7R in eosinophilic and non‑eosinophilic chronic rhinosinusitis with nasal polyps

Molecular Medicine Reports, 2021
Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammation‑mediated disease of the nasal mucosa. P2X7R has been reported to be a potential biomarker for inflammation. The aim of the present study was to explore the role of P2X7R in CRSwNP, and the interaction between P2X7R and the NLRP3 inflammasome in the development of CRSwNP.

Eosinophilic chronic rhinosinusitis in East Asians

World Journal of Clinical Cases, 2014
Chronic rhinosinusitis (CRS) is a common disease worldwide, with a prevalence rate of 5%-15% in the general population. CRS is currently classified into two types: CRS with and without nasal polyps. CRS may also be divided into eosinophilic CRS (ECRS) and non-ECRS subtypes based on the presence of tissue eosinophilic infiltration or not.

Allergic Rhinitis Amplifies Asthma Risk in Patients With Chronic Rhinosinusitis: A Large‐Scale Retrospective Cohort Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and allergic rhinitis (AR) are two highly prevalent airway diseases in the United States. While the coexistence of CRS and asthma is well recognized, less is known about the development of new‐onset asthma in CRS, particularly in the context of comorbid AR. This study assessed the impact of CRS and AR on

Clinical Utility of Machine Learning Methods Using Regression Models for Diagnosing Eosinophilic Chronic Rhinosinusitis

OTO Open
Objective Machine learning methods using regression models can predict actual values of histological eosinophil count from blood eosinophil levels. Therefore, these methods might be useful for diagnosing eosinophilic chronic rhinosinusitis, but their ...

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Rat Model of Staphylococcal Enterotoxin B-Induced Rhinosinusitis [PDF]

Clinical and Experimental Otorhinolaryngology, 2008
ObjectivesIt has been proposed that microbial persistence, superantigen (SA) production, and host T-cell response may be involved in the development of chronic rhinosinusitis.
