毛霉菌病

毛霉菌病(英语:Mucormycosis),部分媒体称之为黑真菌症(black fungus)[3],是毛霉门真菌感染造成的疾病[4],其中以毛霉属根霉属犁头霉属小克银汉霉属真菌的感染为大宗[5][6]。此感染过去称为接合菌病(Zygomycosis),但接合菌门的分类因为复系群而已不再使用,且接合菌门除毛霉外还有些虫霉目蛙粪霉耳霉)的真菌也可感染人类,现多以毛霉菌病、耳霉病英语conidiobolomycosis[7]蛙粪霉病[8]等具体病名称呼。

症状

 
一名感染毛霉菌病的男子脸部出现红肿的病征,右方为其皮肤样本在电子显微镜下发现毛霉菌的孢子囊[9]

毛霉菌多感染鼻窦脑部肺部等部位,还可感染消化道皮肤以及其他器官[10]。病原进入血管后可能导致血栓,造成周围组织因缺血坏死,若侵染脑部与脸面则会造成单侧头痛、发烧、脸面疼痛、鼻腔阻塞并出现黑色黏液、鼻窦炎以及结膜水肿英语Chemosis等症状[11]。感染初期被侵染的部位表面外观正常,随后迅速转为红肿甚至因坏死而呈黑色[12];感染肺部者则会造成呼吸困难、持续咳嗽、咳血腹痛恶心呕吐等症状[10]

治疗

爱滋病糖尿病淋巴瘤等癌症、肝硬化肾功能衰竭病患、接受器官移植者以及长期使用皮质类固醇者被毛霉菌感染的风险较高。两性霉素B为治疗此感染的第一线药物,另外艾沙康唑英语Isavuconazonium也可用于治疗此症[13]。药物治疗一段时间后还需开刀移除被感染的组织[10][14],另外高压氧治疗因可能促进嗜中性球的活性而作为此病的辅助疗法。此病的愈后情况一般不佳[12]

预后

本病往往进展迅速,并且对于大约一半的鼻窦型病例、三分之二的肺部型病例和几乎所有广泛型病例致命[15]。皮肤受累的死亡率最低,但也约为15%[16]

流行病学

毛霉菌的感染相当罕见[10]。2008年美国的一家医院曾爆发毛霉菌病的院内感染,于2014年才被媒体披露[17][18] 。2011年密苏里州受乔普林龙卷风英语2011 Joplin tornado侵袭后当地爆发毛霉菌病的疫情,有十数人被感染,其中5人死亡[19]

2020年COVID-19疫情期间,印度多个城市爆发毛霉菌病感染[20],2021年印度各地又爆发数起感染,可能与COVID-19重症病患接受类固醇治疗后免疫力降低有关[3]

The hospital was extremely aggressive in trying to isolate and then eliminate the source of the fungus.
