Over the past few years nasal cytology has been rarely used in pediatrics, nevertheless its clinical and scientific applications seem to be very promising. The advantages of this technique are different: the ease of performance, the noninvasiveness allowing repetition and the low cost. We evaluated 100 children, from 2 to 15 years old, referred to our outpatient service for allergic children for suspected allergic rhinitis (AR). After skin prick test (SPT) or Radio Allergo Sorbent Test (RAST), 59/100 subjects were classified as affected by AR, while 8 children refused to be tested. According to ARIA guidelines, the 59 children with AR (4 - 15 years old) were divided in 56 with persistent AR and 3 with an intermittent form. Nine out of 59 children with AR had a significant number of neutrophils and eosinophils at the nasal cytology, documenting the presence of “minimal persistent inflammation”. Eleven out of 59 AR patients showed a positive swab for bacteria. Children with nonallergic rhinitis (NAR) were 33/100 (2 - 15 years old). After nasal cytology, 17/33 children were classified as NARES (nonallergic rhinitis with eosinophils), including one X-linked agammaglobulinemia (XLA) child, 1/33 as NARESMA (nonallergic rhinitis with eosinophils and mast cell) and another 1/33 as NARMA (nonallergic rhinitis with mast cell). In conclusion, nasal cytology allowed us to correctly classify children with NAR and to better assess the condition of children with AR.展开更多
目的：评估非变应性鼻炎（nonallergic rhinitis，NAR）患者全身、鼻腔及下气道嗜酸性粒细胞（Eosinophils，EOS）浸润水平及相关性。探讨EOS在NAR患者鼻腔及下气道的特征及意义。方法：2011年6月～2012年6月在我院就诊的NAR患者241例...目的：评估非变应性鼻炎（nonallergic rhinitis，NAR）患者全身、鼻腔及下气道嗜酸性粒细胞（Eosinophils，EOS）浸润水平及相关性。探讨EOS在NAR患者鼻腔及下气道的特征及意义。方法：2011年6月～2012年6月在我院就诊的NAR患者241例，同期征集健康对照组222例，所有受试者均进行病史采集、皮肤点刺实验（SPT）、血清嗜酸性粒细胞、鼻灌洗、诱导痰检查。结果：①NAR组和对照组相比鼻灌洗EOS计数、诱导痰EOS比例、血EOS比例均显著高于健康对照组（P均〈0．01）。②有鼻腔EOS炎症和无鼻腔EOS炎症层的诱导痰EOS百分比阳性率分别为34．7％ vs 9．6％（P〈0．01）。③NAR组鼻灌洗EOS计数和诱导痰EOS比例存在明显相关性（F0．262，P=0．000），鼻灌洗EOS计数和血EOS比例存在明显相关性（r=228，P=0．000），诱导痰EOS比例和血EOS比例存在明显相关性（r==0．291，P=0．000）。结论：NAR患者血液、鼻腔及下气道EOS浸润程度较正常对照组均明显升高，EOS在NAR患者血液、鼻腔及下气道炎症中存在明显一致性，提示NAR是一种全身系统性炎症性疾病；无下气道症状的NAR患者部分存在下气道EOS炎症，鼻腔及血液EOS炎症是导致下气道EOS炎症的主要高危因素。鼻灌洗EOS可能是观测NAR患者下气道炎症及对下气道炎症进行评估和追踪的有效指标。EOS可能是鼻炎、哮喘及血液炎症相关的效应细胞，是上下气道炎症有效生物标记物。展开更多
