我们报告了一例27岁的男性,该男性出现呼吸窘迫,需要机械通气。经支气管镜活检显示肉芽肿内的真菌Emmonsiacrescens的孢子,一种被称为非肉芽肿病的病症。患者接受了两性霉素产品和皮质类固醇,其次是伊曲康唑,完全康复了.月牙是一种分布广泛的昆虫,主要是啮齿动物病原体。本文叙述了自1993年上一次综合病例回顾以来报道的20例人肺脂肪肉芽肿病的临床特点,以及最近报道的Emmonsia属的其他感染。据报道,肺非肉芽肿病主要发生在没有潜在宿主因素的人群中,并且病程为轻度至重度。尚不确定严重的肺性脂肪肉芽肿病的最佳治疗是支持性治疗还是应包括抗真菌治疗。皮质类固醇,或者后两者的组合。Emmonsia属真菌的分类自最初描述以来已经进行了相当大的修改,包括一次被归入金孢子属。分子遗传学已将Emmonsia属与金孢子菌属明显区分开。然而,关于这两个属真菌感染的临床表现,文献中一直存在混淆;为了澄清这个问题,我们对报告的侵袭性金孢子菌感染病例进行了回顾.侵袭性金生孢子菌感染通常发生在受损的宿主中,并且可能具有致命的病程。基于有限的金孢子菌体外敏感性数据,两性霉素B是活性最强的药物,伊曲康唑敏感性是菌株依赖性的,和氟康唑和5-氟胞嘧啶没有活性。
We report a case of a 27-year-old male who presented with respiratory distress that required mechanical ventilation. Transbronchial biopsy revealed adiaspores of the fungus Emmonsia crescens within granulomata, a condition known as adiaspiromycosis. The patient received amphotericin products and corticosteroids, followed by itraconazole, and made a full recovery. Emmonsia crescens is a saprobe with a wide distribution that is primarily a rodent pathogen. The clinical characteristics of the 20 cases of human pulmonary adiaspiromycosis reported since the last comprehensive case
review in 1993 are described here, as well as other infections recently reported for the genus Emmonsia. Pulmonary adiaspiromycosis has been reported primarily in persons without underlying host factors and has a mild to severe course. It remains uncertain if the optimal management of severe pulmonary adiaspiromycosis is supportive or if should consist of antifungal treatment, corticosteroids, or a combination of the latter two. The classification of fungi currently in the genus Emmonsia has undergone considerable revision since their original description, including being grouped with the genus Chrysosporium at one time. Molecular genetics has clearly differentiated the genus Emmonsia from the
Chrysosporium species. Nevertheless, there has been a persistent confusion in the literature regarding the clinical presentation of infection with fungi of these two genera; to clarify this matter, the reported cases of invasive
Chrysosporium infections were reviewed. Invasive
Chrysosporium infections typically occur in impaired hosts and can have a fatal course. Based on limited in vitro susceptibility data for
Chrysosporium zonatum, amphotericin B is the most active drug, itraconazole susceptibility is strain-dependent, and fluconazole and 5-fluorocytosine are not active.
