Abstract

Purpose of review: We aimed to review the latest evidence regarding the value of tissue histopathological analysis in chronic rhinosinusitis with nasal polyps (CRSwNP) and to facilitate tissue analysis by proposing a pragmatic checklist for clinical settings.

Recent findings: CRSwNP is a chronic inflammatory disease that severely impairs the patient's quality of life. The severity of the disease can be correlated with nasal polyps enriched in eosinophils/IL-5 and, although ≥ 10 eosinophils per high power field are considered enough to determine an eosinophilic CRS, this cut-off value, the biopsy method, and the sampling location are still a matter of debate. Besides, tissue eosinophil values might also have some added value when combined with other cellular counts (e.g., eosinophil-to-lymphocyte ratio, Charcot-Leyden crystals). Structured histopathology analysis of sinonasal tissue-including, for instance, tissue remodelling biomarkers, fibrosis, and eosinophilic aggregates-has proven to be a valuable tool for healthcare professionals to identify different pheno-endotypes of CRSwNP and to improve the prioritisation of candidates to targeted therapies. Patients with CRSwNP are treated according to their severity with corticosteroids (intranasal and systemic), endoscopic sinus surgery, and/or biological therapy. A panel of expert ear, nose, and throat specialists and pathologists proposed a pragmatic checklist to improve the clinical practice around tissue analysis in CRSwNP, to facilitate communication between hospital-based healthcare professionals, and to standardize the evaluation of inflammatory biomarkers.

当鼻子遇到实验室:用于常规临床实践的慢性鼻窦炎伴鼻息肉的组织病理学分析。
综述目的:我们旨在回顾有关组织病理学分析在慢性鼻炎伴鼻息肉(CRSwNP)中的价值的最新证据,并通过提出一份适用于临床环境的实用检查表来促进组织分析:最新研究结果:CRSwNP 是一种慢性炎症性疾病,严重影响患者的生活质量。该疾病的严重程度与鼻息肉中富含的嗜酸性粒细胞/IL-5相关,虽然每个高倍视野中嗜酸性粒细胞≥10个足以判定为嗜酸性粒细胞性CRS,但这一临界值、活检方法和取样位置仍存在争议。此外,如果将组织嗜酸性粒细胞值与其他细胞计数(如嗜酸性粒细胞与淋巴细胞比值、Charcot-Leyden 晶体)结合起来,可能会有一些附加价值。事实证明,鼻窦组织的结构组织病理学分析--包括组织重塑生物标志物、纤维化和嗜酸性粒细胞聚集等--是医护人员识别 CRSwNP 不同表型的重要工具,也是改善靶向疗法候选者优先排序的重要工具。CRSwNP 患者可根据其严重程度接受皮质类固醇(鼻内和全身)、内窥镜鼻窦手术和/或生物治疗。一个由耳鼻喉科专家和病理学家组成的专家小组提出了一份实用检查表,以改进围绕 CRSwNP 组织分析的临床实践,促进医院医护人员之间的沟通,并使炎症生物标志物的评估标准化。

期刊介绍: The aim of Current Allergy and Asthma Reports is to systematically provide the views of highly selected experts on current advances in the fields of allergy and asthma and highlight the most important papers recently published. All reviews are intended to facilitate the understanding of new advances in science for better diagnosis, treatment, and prevention of allergy and asthma. We accomplish this aim by appointing international experts in major subject areas across the discipline to review select topics emphasizing recent developments and highlighting important new papers and emerging concepts. We also provide commentaries from well-known figures in the field, and an Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. Over a one- to two-year period, readers are updated on all the major advances in allergy and asthma.
