Chronic Rhinosinusitis’s with Nasal Polyps
Journal of Pharmaceutical Research International, 2021
Chronic Rhinosinusitis is a chronic disease that negatively affects the quality of life. When associated with nasal polyps, there is worsening of the condition, and it becomes harder to treat due to the high rates of recurrence and the increased morbidity rates. Though having a set treatment method, the condition still has unknown etiology and pathophysiology, which makes it extremely hard to diagnose and evaluate. Due to these unknown factors, treatment is still not as precise and effective; we still rely on systemic drugs like corticosteroids which most often do not resolve the disease, and we then present surgical options, though effective still do not pose as an effective cure, which may be a factor in the high rate of recurrences. However, there have been giant leaps in the specialized research of this particular topic, leading to classification through biomarkers allowing us to study and consolidate data on the disease pathology and all of the different options causing recurre...

Background and Objectives: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial disease resulting from inflammation of the nasal cavity and paranasal sinuses. Systemic allergic inflammation is an important cause of CRSwNP; however, the effect of local allergic inflammation is unclear. This study was designed to investigate the effect of local allergic inflammation in CRSwNP.Materials and Methods: The study included 11 patients with CRSwNP and 18 control subjects. Olfactory function was measured with the Korean Version of Sniffin’s stick test. Nasal lavage fluids (NLFs) were collected from all subjects and analyzed for total IgE, eosinophilic cationic protein (ECP), and cytokines (tumor necrosis factor [TNF]-α, interleukin [IL]-4, IL-10, IL-17A, interferon-γ). Flow cytometry was used to measure various inflammatory cells in the NAL fluids.Results: On analysis of flow cytometry and enzyme-linked immunosorbent assay, we found that CRSwNP patients had significantly incr...
The Relationship of Chronic Rhinosinusitis with Nasal Polyps and PDL-1
BJSTR, 2021
hronic rhinosinusitis with nasal polyps (CRSwNP) are benign inflammatory and hyperplastic outgrowths of the sinonasal mucosa [1]. It is a disease that seriously affects the quality of life of patients by causing nasal congestion, snoring, postnasal discharge, nasal discharge, loss of sense of smell/taste. The prevalence of CRSwNP is 1% to 4% in the general population [2]. CRSwNP is observed more frequently in male patients between the 4th and 6th decades.

Chronic rhinosinusitis (CRS) with and without nasal polyps represent different stages of one chronic inflammatory disease of the mucosa of the nasal cavity and paranasal sinuses. Coexistence of chronic rhinosinusitis with nasal polyps and asthma and rather similar characteristics of inflammation support assumption that chronic rhinosinusitis and nasal polyps and asthma may be, at least in part, the same disease process. We therefore aimed to evaluate the differences of sinus radiologic findings, systemic inflammation and allergy markers, pulmonary function of chronic rhinosinusitis associated with nasal polyps and asthma. A total of 121 patients with chronic rhinosinusitis referred to tertiary center were evaluated; 23 healthy persons served as controls. Sinus CT scans and nasal endoscopy were performed. Allergic rhinitis was diagnosed according to history and positive skin prick tests to common inhalant allergens. Asthma was diagnosed according to GINA by history and pulmonary func...
Cellular phenotyping of chronic rhinosinusitis with nasal polyps
Rhinology, 2016
Defining the phenotypes of chronic rhinosinusitis with nasal polyps (CRSwNP) with prognosis may lead to delivery of personalized treatment. This study aimed to identify cellular phenotypes of CRSwNP using cluster analysis and define an algorithm for different clusters associated with polyp recurrence. Overall, 366 patients with CRSwNP were enrolled in this retrospective analysis. Eighteen variables, including clinical characteristics and tissue/peripheral inflammatory cells assessments, were selected for factor analysis. Unsupervised cluster analysis was performed after variables reduction and standardization and differences in polyp recurrence during follow-up for a minimum of 24 months were analysed among clusters. Discriminant analysis was further used to develop a clinically useful algorithm for predicting clustering. Five phenotypic clusters were identified. Clusters 1 and 2 were plasma cell-dominant and lymphocyte-dominant phenotypes, respectively. Cluster 3 revealed a mixed i...

The complex pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP) generates a spectrum of phenotypes with a wide variety of inflammatory states. We enrolled 44 very-likely-to-be type 2 CRSwNP patients in order to evaluate the load of inflammation and to analyze human interleukins in nasal secretion. Clinical data were collected to evaluate the severity of the disease. High levels of IL-5, IL-4, IL-6, and IL-33 were detected in all type 2 CRSwNP patients. By analyzing type 2 cytokine profiles and local eosinophil count, we identified two coherent clusters: the first was characterized by high levels of IL-4, IL-5, IL-6, and a high-grade eosinophil count (type 2-high); the second had lower levels of cytokines and poor or absent eosinophilic inflammation (type-2 low). IL-5 levels were significantly higher within the type 2 cytokine and it was the most reliable biomarker for differentiating the two clusters. In type 2-high inflammatory profile clinical scores, the mean num...
