研究目的:

针对我国菌阴肺结核诊断难、分子诊断覆盖率低的问题,本研究拟构建“回顾性队列+前瞻性队列”双队列体系:回顾性队列收集3500例既往真实诊疗环境中菌阴肺结核患者数据与标本,明确基线病原学阳性率;前瞻性队列纳入1500例菌阴肺结核患者,在临床诊疗中规范增加气管镜和穿刺检测数量,提高肺结核样本检测量和检测率。采用分子诊断技术对获取的痰、肺泡灌洗液、组织标本等进行结核菌检测。首先采用荧光定量PCR初筛,结核菌阴性标本再用高灵敏度tNGS进一步检测,提高病原学阳性率;对病原学阳性患者,采用高分辨熔解曲线和tNGS检测耐药相关基因,提升耐药检测覆盖率。本课题最终将纳入不少于5000例菌阴肺结核患者,实现提升肺结核患者病原学阳性率10%,及提高耐药结核检测覆盖率。通过对比双队列病原学阳性率,验证技术效能,为肺结核精准诊断提供技术支撑,也为其他子课题完善疾病谱中菌阴/菌阳比例提供数据依据。  

Objectives of Study:

To address the challenges in diagnosing smear-negative pulmonary tuberculosis and the low coverage of molecular diagnostics in China, this study aims to construct a dual-cohort system comprising a retrospective cohort and a prospective cohort. The retrospective cohort will collect data and specimens from 3500 patients with smear-negative pulmonary tuberculosis in real-world diagnostic and treatment settings to establish the baseline etiological positivity rate. The prospective cohort will enroll 1500 patients with smear-negative pulmonary tuberculosis, in whom the utilization of bronchoscopy and puncture procedures will be standardized and increased during clinical diagnosis and treatment to enhance the sample throughput and detection rate for tuberculosis testing. Molecular diagnostic techniques will be employed to detect Mycobacterium tuberculosis in obtained specimens, including sputum, bronchoalveolar lavage fluid, and tissue samples. Fluorescence quantitative PCR will be used as the initial screening method, and specimens testing negative for Mycobacterium tuberculosis will undergo further testing with highly sensitive targeted next-generation sequencing to improve the etiological positivity rate. For etiologically positive patients, high-resolution melting curve analysis and targeted next-generation sequencing will be used to detect drug resistance-related genes, thereby enhancing the coverage of drug resistance testing. This project will ultimately enroll no fewer than 5000 patients with smear-negative pulmonary tuberculosis, aiming to achieve a 10% increase in the etiological positivity rate among tuberculosis patients and improve the coverage of drug resistance testing for tuberculosis. By comparing the etiological positivity rates between the two cohorts, the technical efficacy will be validated, providing technical support for the precise diagnosis of pulmonary tuberculosis and offering data to refine the proportion of smear-negative/smear-positive cases in the disease spectrum for other sub-projects.

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Sputum specimens were negative by smear, culture, and molecular testing, but the clinical symptoms were consistent with pulmonary tuberculosis.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

对痰、支气管肺泡灌洗液和病理组织标本等行多标本分子检测:包括荧光定量PCR检测结核特异基因片段诊断结核病;病原学阳性的患者进一步做探针溶解曲线明确患者耐药性;对无病原学依据和耐药信息的患者行tNGS检测,同时明确病原学依据和耐药性。

Index test:

For multiple specimen types including sputum, bronchoalveolar lavage fluid, and pathological tissue, molecular testing was performed as follows: Fluorescence quantitative PCR was used to detect tuberculosis-specific gene fragments for the diagnosis of tuberculosis. For patients with positive etiological evidence, probe-based melting curve analysis was further conducted to determine drug resistance. For patients lacking etiological evidence or resistance information, targeted next-generation sequencing (tNGS) was performed to simultaneously establish etiological diagnosis and resistance profile.
