Systemic Predictors of Eosinophilic Chronic Rhinosinusitis

American Journal of Rhinology and Allergy, 2018
Background Eosinophilic chronic rhinosinusitis (eCRS) is linked with skewed T-helper 2 or immunoglobulin E (IgE)-mediated allergic responses, with differing diagnosis, prognosis, and management to non-eCRS. Objective The association ...

Peripheral blood eosinophil levels in chronic rhinosinusitis and its predictive value in eosinophilic chronic rhinosinusitis

Acta Oto-Laryngologica, 2021
The prevalence of eosinophilic CRSwNP in China has increased significantly over the last 20 years, noninvasive methods that could assist in diagnosis are urgently needed.The aim of this study is to explore the clinical significance of peripheral blood eosinophil in diagnosing ECRS.We conducted a prospective study of 221 patients diagnosed with CRS ...

Eosinophilic Bacterial Chronic Rhinosinusitis

The Laryngoscope, 2007
AbstractBackground: A subset of Chronic Rhinosinusitis (CRS) patients are those with eosinophilic CRS (ECRS). These patients remain the most refractory to medical and surgical intervention, and are thought to reflect an inflammatory process arising from a variety of causes.

Systemic biomarkers of eosinophilic chronic rhinosinusitis

Current Opinion in Allergy & Clinical Immunology, 2020
Purpose of review The current understanding of eosinophilic chronic rhinosinusitis (CRS) has developed rapidly over the past decades. Classification of CRS based on the inflammatory endotype more accurately reflects the underlying pathophysiology and better directs treatment.

Calprotectin in chronic rhinosinusitis eosinophil extracellular traps

International Forum of Allergy & Rhinology, 2023
AbstractBackgroundCalprotectin is an antimicrobial peptide primarily secreted by neutrophils. Furthermore, calprotectin secretion increases in patients with chronic rhinosinusitis (CRS) with polyps (CRSwNP) and positively correlates with neutrophil markers.

Categorization of eosinophilic chronic rhinosinusitis

Current Opinion in Otolaryngology & Head and Neck Surgery, 2004
The presence of eosinophilia histopathologically in sinusitis is frequently associated with greater disease objectively and a decreased likelihood of surgical success. Eosinophilic chronic rhinosinusitis encompasses a wide variety of etiologies and associations that can be grouped under this umbrella term.

Topography of polyp recurrence in eosinophilic chronic rhinosinusitis

International Forum of Allergy & Rhinology, 2020
Background Eosinophilic chronic rhinosinusitis (eCRS) is an inflammatory endotype of CRS. Contemporary treatment includes creation of a “neo‐sinus” cavity and postoperative corticosteroid irrigations. Not all patients gain control with local therapy.

Differential diagnosis of eosinophilic chronic rhinosinusitis

Current Allergy and Asthma Reports, 2006
Eosinophilic chronic rhinosinusitis (ECRS) encompasses a wide variety of etiologies. To date, a unifying pathophysiologic mechanism remains elusive. Eosinophilia is frequently, but not exclusively, caused by immunoglobulin (Ig)E-mediated hypersensitivity and is dominated by the associated cytokine milieu of Th2 inflammation.

The role of interleukin-16 in eosinophilic chronic rhinosinusitis

European Archives of Oto-Rhino-Laryngology, 2007
Eosinophilic granulocytes (Eos) are found in great numbers both in the tissue and in the mucus of patients suffering from chronic rhinosinusitis with polyposis (ECRS). Interleukin-16 (IL-16) is known as a highly potent chemotactic and chemoattractant molecule (ED 10-11) for Eos.

Eosinophilic esophagitis strongly linked to chronic rhinosinusitis

The Laryngoscope, 2015
Objectives/HypothesisTo determine the relative risk of having eosinophilic esophagitis (EoE) coexist with chronic rhinosinusitis (CRS) in probands and their families using the Utah Population Database (UPDB).MethodsThis retrospective observational cohort study with population‐based matched controls utilized the UPDB, a genealogical database linked to ...
