Glycosoaminoglycans in nasal polyps.

Acta Otolaryngol

Department of General and Analytical Chemistry, Silesian Academy of Medicine, Sosnowiec, Poland.

Published: February 2005

Conclusion: The qualitative and quantitative compositions of GAGs were comparable in all the polyps examined.

Objective: Glycosoaminoglycans (GAGs) are an integral component of proteoglycans, which are constituents of connective tissue. The qualitative and quantitative compositions of GAGs occurring in proteoglycans determine their biological role. In this work, individual fractions of GAGs occurring in nasal polyps were isolated and estimated.

Material And Methods: Polyps were obtained over a 2-year period from 31 patients (18 males, 13 females; age range 28-70 years) who underwent polypectomy and evaluated using routine histopathology.

Results: The amount of hyaluronic acid in nasal polyps was high, the amounts of dermatane sulphate and chondroitine-6-sulphate were slightly lower and the amounts of chondroitine-4-sulphate, heparin, heparan sulphate and keratan sulphate were the lowest.

Background: Chronic Transforming Growth Factor Beta 1 (TGF-β1) plays a critical role in tissue remodelling and immunological modulation, which may contribute to the severity and recurrence of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). Despite extensive research on CRSwNP, the exact role and pathological significance of TGF-β1 in CRSwNP remain poorly understood due to inconsistencies in study methodologies and findings.

Aims/objectives: To resolve discrepancies in the literature, this systematic review compares the levels of TGF-β1 in CRSwNP tissue to controls and Chronic Rhinosinusitis without Nasal Polyps (CRSsNP).

Background Chronic rhinosinusitis with nasal polyps (CRSwNP) significantly affects patients' quality of life, impacting both physical and psychological well-being. This study investigated the potential role of resilience in coping with CRSwNP and its relationship to disease severity and cellular proliferation. Methodology Between July 1, 2021, and June 30, 2022, 30 patients diagnosed with CRSwNP were enrolled in a study at Cardiomed Hospital in Cluj-Napoca, Romania.

Objective: This study was undertaken to assess the association between the likelihood of surgical recurrence and serum ECP and TIgE levels in chronic rhinosinusitis with nasal polyps (CRSwNP).

Methodology: Clinical information was gathered retrospectively from 166 cases of surgically treated CRSwNP as well as 60 cases of chronic rhinosinusitis without nasal polyps (CRSsNP). A comparative analysis on serum levels of total immunoglobulin E (TIgE) and eosinophil cationic protein (ECP) was carried out between the two groups.

HMOX1 as a potential drug target for upper and lower airway diseases: insights from multi-omics analysis.

Background: Oxidative stress is key in inflammatory airway diseases. Heme oxygenase 1 (HMOX1) regulates oxidative stress, but its role in airway diseases needs exploration.

Methods: Differentially expressed genes (DEGs) between healthy nasal mucosa and chronic rhinosinusitis with nasal polyps (CRSwNP) were identified from Gene Expression Omnibus (GEO).

SLAMF8 Disrupts Epithelial Barrier in Chronic Rhinosinusitis with Nasal Polyps via M1 Macrophage Polarization.

Ann Allergy Asthma Immunol

January 2025

Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University, Qingdao, China. Electronic address:

Background: Recent studies show that M1 macrophages accumulate predominantly in non-eosinophilic chronic rhinosinusitis with nasal polyps (neCRSwNP). However, the precise mechanisms regulating M1 macrophages and their impact on the epithelial barrier remain unclear.

Objective: We aim to investigate the expression and regulatory role of SLAMF8, a molecule exclusively expressed in myeloid cells, in M1 macrophage polarization and its potential contribution to neCRSwNP development.
