目的
2
总结我国南方城市肺毛霉菌病(PM)的临床特征及预后,同时探讨宏基因组二代测序(mNGS)在PM诊断中的价值。
方法
2
回顾性分析中山大学附属第一医院2019年1月1日至2022年1月31日期间诊断为PM且曾行mNGS检测的病例,共纳入14例,确诊 4例,临床诊断10 例,收集其临床表现、诊治及预后资料。
结果
2
所有患者均有基础疾病,血液系统恶性肿瘤和糖尿病最常见。最常见的症状是发热(10例)、咳嗽(9例)和气促(9例)。胸部CT形态以实变影最多见,其次为肿块影,多伴空洞。实验室检查方面,CD4+T淋巴细胞下降、CD8+T淋巴细胞升高以及CD4+/CD8+比下降提示预后不良。CT影像学合并胸腔积液的患者预后更差。mNGS诊断的阳性率为 78.5 %,明显高于组织病理(50%)及肺泡灌洗液深部真菌快速荧光染色直接镜检(61.5%)、真菌培养(23.1%)。
结论
2
肺毛霉菌病好发于有基础疾病或免疫功能低下患者,临床表现缺乏特异性,较低的CD4/CD8 比率及CT影像学合并胸腔积液的患者预后更差,mNGS诊断PM快速便捷、敏感性高,在诊断PM中具有优势。
Objective
2
To summarize the clinical features and prognosis of pulmonary mucormycosis (PM) in southern China, and to explore the diagnostic value of metagenomic next generation sequencing (mNGS) in PM.
Methods
2
The clinical manifestations, diagnosis, treatment and prognosis of patients diagnosed with PM in The First Affiliated Hospital of Sun Yat-sen University from January 1, 2019 to January 31, 2022 who had undergone mNGS detection in lung tissue or alveolar lavage fluid were collected retrospectively. A total of 14 patients with PM were included, including 4 patients with confirmed diagnosis and 10 patients with clinical diagnosis.
Results
2
All patients had underlying medical conditions, with hematological malignancies and diabetes being the most common. The most common symptoms were fever
(n
= 10), cough (
n
= 9) and shortness of breath (
n
= 9). Consolidation was the most common sign of chest CT, followed by mass, mostly with cavity. On laboratory tests, decreased CD4+T lymphocytes, elevated CD8+T lymphocytes, and decreased CD4+/CD8+ ratio, and presentation with pleural effusion indicate poor prognosis. The positive rate of mNGS diagnosis was 78.5%, which was significantly higher than that of histopathology (50%), fungus rapid fluorescence staining (61.5%) and fungal culture (23.1%) of bronchoalveolar lavage fluid.
Conclusions
2
Pulmonary mucormycosis is more likely to occur in patients with underlying diseases or who are immunocompromised. The clinical manifestations lack specificity. The low CD4/CD8 ratio and presentation of pleural effusion on CT imaging indicate poor prognosis of patients. mNGS is a rapid, convenient and sensitive method for the diagnosis of PM, which has advantages in the diagnosis of pulmonary mucormycosis.
