【摘要】 目的 探讨嗜酸性粒细胞(Eos)与慢性鼻-鼻窦炎伴鼻息肉(CRSwNP)的临床特征的关系。方法 62例慢性鼻-鼻窦炎伴鼻息肉并行鼻内镜下鼻窦开放手术患者, 根据外周血嗜酸性粒细胞比例, 分为Eos组与正常密度嗜酸性粒细胞(NEos)组。比较两组患者鼻息肉组织嗜酸性粒细胞计数、鼻腔鼻窦结局测量20条(SNOT-20)评分以及鼻窦CT 的Lund-Mackay 评分等。结果 Eos组鼻息肉组织中的嗜酸性粒细胞计数显著高于NEos组(P<0.05);Eos组的SNOT-20评分略低于NEos组, 差异无统计学意义(P>0.05), 鼻息肉组织中嗜酸性粒细胞计数与SNOT-20评分无相关性(r=0.246, P=0.126>0.05);两组CT的Lund-Mackay评分比较差异有统计学意义(P<0.05);外周血嗜酸性粒细胞比例与组织病理学结果呈正相关(r=0.512, P<0.05), ROC曲线下面积 (AUC)为0.808, 截断值为3.65%, 其对嗜酸性粒细胞性慢性鼻-鼻窦炎合并鼻息肉(ECRSwNP)诊断的灵敏度和特异度分别为78.9%和71.4%。结论 嗜酸性粒细胞影响慢性鼻-鼻窦炎合并鼻息肉的临床特征, ECRSwNP诊断时注意外周血嗜酸性粒细胞的比例, 从而为患者制定合适的治疗策略。

【Abstract】 Objective To investigate relationship of clinical characteristics between eosinophils (Eos) and chronic rhinosinusitis with nasal polyp (CRSwNP). Methods A total of 62 chronic rhinosinusitis with nasal polyp patients receiving endoscopic sinus open surgery were divided by peripheral blood eosinophils proportion into Eos group and normal density Eos (NEos) group. Comparison was made on eosinophils count in polyp tissue, sino-nasal outcome test-20 (SNOT-20) score and Lund-Mackay score of nasal sinus CT between the two groups. Results Eos group had obviously higher eosinophils count in polyp tissue than NEos group (P<0.05). Eos group had lower SNOT-20 score than NEos group, and the difference had no statistical significance (P>0.05). Eosinophils count in polyp tissue and SNOT-20 was not correlated (r=0.246, P=0.126>0.05). The difference of CT Lund-Mackay scores had statistical significance between the two groups (P<0.05). Peripheral blood eosinophils proportion was positively correlated with histopathological outcome (r=0.512, P<0.05). Area under curve (AUC) of ROC was 0.808, with cutoff value as 3.65%. It contained sensitivity and specificity as 78.9% and 71.4% in diagnosis of eosinophils chronic rhinosinusitis with nasal polyp (ECRSwNP). Conclusion Eosinophils has effects on clinical characteristics of chronic rhinosinusitis with nasal polyp. It is necessary to pay attention to peripheral blood eosinophils proportion in diagnosing ECRSwNP, in order to make appropriate treatment strategy for patients.

慢性鼻-鼻窦炎(chronic rhinosinusitis, CRS)是一种常见病, 欧美的发病率为5%~15%[1], 我国的发病率为8%~15%[2]。慢性鼻-鼻窦炎的发病机制比较复杂, 至今未能完全阐明, 但近年来的研究发现嗜酸性粒细胞(eosinophils, Eos)的浸润在慢性鼻-鼻窦炎发病中发挥着重要作用, 尤其是在伴鼻息肉的病例中。本研究旨在通过临床资料回顾性分析慢性鼻-鼻窦炎伴鼻息肉患者外周血及组织中Eos的差异与患者临床表现、诊断间的关系, 为慢性鼻-鼻窦炎伴鼻息肉的诊断和治疗提供新理论参考依据, 报告如下。
1 资料与方法
1. 1 一般资料 选取2014 年6 月~2015 年6 月住院诊断为慢性鼻-鼻窦炎伴鼻息肉并行鼻内镜下鼻窦开放手术的62 例患者。其中男33例(53.2%), 女29例(46.8%), 年龄18~74 岁, 平均年龄46.32岁。排除合并慢性病如高血压、糖尿病及心脏病等、既往有手术史者、上颌窦后鼻孔息肉及出血坏死性息肉等患者。所有患者在接受研究前均未进行规范系统药物治疗。查……
