Fungal rhinosinusitis is on the rise worldwide and it is endemic especially in North India. The main purpose of this study was to determine the antifungal resistance profile of fungal isolates from the cases of fungal rhinosinusitis. Antifungal susceptibility testing of isolated fungi to fluconazole, amphotericin B, itraconazole, and voriconazole was determined by standard CLSI broth microdilution method. Sixty-eight fungal isolates of . ( = 49), ( = 9), . ( = 4), . ( = 2), . ( = 2), . ( = 1), and . ( = 1) were obtained from 60 different clinical samples as exudate from nasal mucosa ( = 28), allergic mucin ( = 8), nasal lavage ( = 2), tissue biopsy from nasal polyps ( = 14), and intraoperative nasal mucosa ( = 8). Of the 68 isolates, 75% were resistant to fluconazole, 13.23% were resistant to itraconazole, 2.94% to amphotericin B, and none were resistant to voriconazole. (5%) was the only fungi found resistant to amphotericin B, while against itraconazole, flavus (7.5%) and (100%) were found resistant. All the isolates of , , , and spp. were resistant to fluconazole. Although amphotericin B stills remains to be the most effective drug, more prospective studies are needed for the requirement of knowledge of the sensitivity pattern for optimal treatment and reduction in morbidity in the long run.
真菌性鼻-鼻窦炎在全球范围内呈上升趋势,在印度北部尤为流行。本研究的主要目的是确定从真菌性鼻-鼻窦炎病例中分离出的真菌的抗真菌耐药谱。
通过标准的美国临床和实验室标准协会(CLSI)肉汤微量稀释法测定分离出的真菌对氟康唑、两性霉素B、伊曲康唑和伏立康唑的药敏试验。
从60份不同的临床样本中获得了68株真菌分离株,包括鼻黏膜渗出物(n = 28)、变应性黏液(n = 8)、鼻腔灌洗物(n = 2)、鼻息肉组织活检(n = 14)和术中鼻黏膜(n = 8),分离株分别为:烟曲霉(n = 49)、黄曲霉(n = 9)、黑曲霉(n = 4)、构巢曲霉(n = 2)、土曲霉(n = 2)、杂色曲霉(n = 1)和白曲霉(n = 1)。在这68株分离株中,75%对氟康唑耐药,13.23%对伊曲康唑耐药,2.94%对两性霉素B耐药,对伏立康唑均无耐药。烟曲霉(5%)是唯一对两性霉素B耐药的真菌,而对于伊曲康唑,发现黄曲霉(7.5%)和构巢曲霉(100%)耐药。所有烟曲霉、黄曲霉、黑曲霉和构巢曲霉属的分离株均对氟康唑耐药。
尽管两性霉素B仍然是最有效的药物,但从长远来看,为了获得最佳治疗的敏感性模式知识并降低发病率,仍需要更多的前瞻性研究。
