应用宏基因二代测序技术(mNGS)检测非中性粒细胞减少性肺真菌感染患者肺泡灌洗液真菌表达,通过与对比传统检测方法(真菌培养、G试验、GM试验),探讨mNGS病原检测的诊断价值。  

Objectives of Study:

This study employed metagenomic next-generation sequencing (mNGS) to detect fungal pathogens in bronchoalveolar lavage fluid (BALF) from patients with non-neutropenic pulmonary fungal infections. By comparing mNGS results with those from conventional methods (including fungal culture, G-test, and GM-test), we aimed to evaluate the diagnostic value of mNGS for pathogen detection.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据来源与采集 本研究为一项单中心、回顾性、观察性研究。数据来源于 宜昌市中心人民医院的电子病历系统(嘉禾电子病例系统)、实验室信息系统(LIS)及影像归档系统(PACS)。我们通过系统检索 2018年12月1日至2025年8月31日 期间,出院诊断包含肺真菌感染、肺曲霉菌感染、肺曲霉菌病 的所有患者。随后,由两名研究人员独立查阅纸质及电子病历,根据预设的 [纳排标准] 进行筛选,最终确定研究队列。基于研究目的,我们设计了标准化的电子病例报告表(e-CRF),用于提取以下信息:① 人口统计学资料(年龄、性别等);② 临床基线特征(合并症、疾病严重程度评分等);③ 诊疗信息(治疗方案);④ 实验室及影像学检查结果。所有数据由 两名经过统一培训的临床研究员独立采集,如有分歧,则通过讨论或由 第三位资深临床专家仲裁决定。 数据管理 数据录入与存储:采集的数据采用“双人背对背”模式录入至WPS EXcel 软件中,并进行一致性校验。最终数据库存储于医院内网加密计算机中,所有患者信息均进行去标识化处理,仅以唯一研究编号标识。 隐私与伦理:本研究方案已获得宜昌市中心人民医院伦理委员会的审核批准(批件号:2025-277-01),鉴于其回顾性性质且所有数据均进行匿名化处理,伦理委员会批准豁免患者知情同意。本研究全过程严格遵守患者隐私保护原则。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study is a single-center, retrospective, observational study. Data were sourced from the electronic medical record system (Jiahe EMR System), laboratory information system (LIS), and picture archiving and communication system (PACS) of Yichang Central People's Hospital. We systematically retrieved all patients diagnosed with pulmonary fungal infection, pulmonary aspergillus infection, or pulmonary aspergillosis between December 1, 2018, and August 31, 2025. Two researchers independently reviewed both paper and electronic medical records according to predefined inclusion and exclusion criteria to finalize the study cohort. Based on the study objectives, a standardized electronic case report form (e-CRF) was designed to extract the following information: ① Demographic data (e.g., age, sex); ② Clinical baseline characteristics (e.g., comorbidities, disease severity scores); ③ Treatment information (e.g., treatment regimens, drug dosage); ④ Laboratory and imaging results; All data were independently collected by two uniformly trained clinical researchers. Any discrepancies were resolved through discussion or adjudication by a third senior clinical expert. Data Management Data Entry and Storage: Collected data were entered into WPS Excel software using a "double-entry independent" method, followed by consistency checks. The final database was stored on an encrypted computer within the hospital’s internal network. All patient information was de-identified and labeled only with a unique study code. Privacy and Ethics: The study protocol was reviewed and approved by the Ethics Committee of Yichang Central People's Hospital (Approval No.: 2025-277-01). Due to the retrospective nature of the study and the anonymization of all data, the ethics committee granted an exemption from informed consent. The entire study process strictly adhered to patient privacy protection principles.
