In recent years fungi are favoured as origin of chronic rhinosinusitis (CRS), especially with nasal polyps (wNP). Sensitive methods for fungal detection are still absent, therefore we used NP tissue single-cell suspension for mycology investigations in patients with recalcitrant NP (rNP) that underwent functional endoscopic sinus surgery (FESS). A prospective case-series study and culture-based mycological examination were conducted in patients who underwent FESS for the first time (ft-FESS) and those with repeated FESS (re-FESS). The study was conducted in a tertiary Otorhinolaryngology Unit of Clinical Centre of Serbia. A total of 43 consecutive patients with CRSwNP underwent FESS. Culture-based mycological examination of single-cell suspension was done on 55 NPs samples. Patient's co-morbidity data were collected. Repeated FESS was observed in 19/43 (44 %) patients (re-FESS group). Asthma and aspirin intolerance were more frequent in re-FESS than in ft-FESS group (p = 0.000, p = 0.002; respectively). Fungi were detected (wF) in 10/43 (23.3 %) patients (FESSwF group), representing 13/55 culture positive NP tissue (23.6 %). Fungal presence was higher in re-FESS than in ft-FESS group (42 and 8 %, respectively; p = 0.01). Significantly longer duration of CRS was observed in FESSwF than in fungal negative patients (p = 0.033). Predominate strain was Aspergillus flavus detected in 6/10 patients. This is the first study which analysed association of fungi in single-cell suspension of NP tissue and rNP. We demonstrate significantly higher percentage of positive fungal finding in re-FESSwF than in ft-FESSwF group. The most commonly isolated species in our patients was A. flavus.
近年来,真菌被认为是慢性鼻-鼻窦炎(CRS)尤其是伴鼻息肉(wNP)的病因。目前仍缺乏灵敏的真菌检测方法,因此我们将鼻息肉组织单细胞悬液用于接受功能性鼻内镜鼻窦手术(FESS)的难治性鼻息肉(rNP)患者的真菌学研究。对首次接受FESS(ft-FESS)和多次接受FESS(re-FESS)的患者进行了一项前瞻性病例系列研究及基于培养的真菌学检查。该研究在塞尔维亚临床中心的三级耳鼻咽喉科进行。共有43例连续性CRSwNP患者接受了FESS。对55份鼻息肉样本进行了基于培养的单细胞悬液真菌学检查。收集了患者的合并症数据。19/43(44%)例患者接受了多次FESS(re-FESS组)。与ft-FESS组相比,re-FESS组中哮喘和阿司匹林不耐受更为常见(分别为p = 0.000,p = 0.002)。10/43(23.3%)例患者检测到真菌(wF)(FESSwF组),占13/55份培养阳性的鼻息肉组织(23.6%)。re-FESS组中真菌检出率高于ft-FESS组(分别为42%和8%;p = 0.01)。FESSwF组CRS病程显著长于真菌阴性患者(p = 0.033)。主要菌株为黄曲霉,在6/10例患者中检测到。这是第一项分析鼻息肉组织单细胞悬液中的真菌与rNP之间关联的研究。我们发现re-FESSwF组真菌阳性检出率显著高于ft-FESSwF组。我们的患者中最常分离出的菌种是黄曲霉。
