研究目的:

本次临床研究的目的是利用一种新的床旁核酸检测技术,检测脑脊液中的结核分枝杆菌复合群,评价这种床旁核酸检测技术在结核性脑膜炎诊断中的应用价值。本研究在医院床旁对结核分枝杆菌复合群的快速诊断具有重要的临床意义,可为临床结核性脑膜炎的早期诊断提供更加可靠的依据。  

Objectives of Study:

This clinical study aims to assess a novel point-of-care nucleic acid amplification test (POC-NAAT) for detecting Mycobacterium tuberculosis complex (MTBC) in cerebrospinal fluid (CSF) and to evaluate its diagnostic utility for tuberculous meningitis (TBM). Rapid bedside identification of MTBC holds substantial clinical value and may furnish more reliable evidence to support the early diagnosis of TBM.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄≥18岁,住院期间接受过腰椎穿刺检查,留存有完整的脑脊液样本 2.具有结核性脑膜炎相关临床表现,如发热、头痛、意识障碍、颈项强直、脑神经损害等; 3.经影像学检查(如头颅CT/MRI)提示颅内炎性病变、脑膜强化或脑积水等支持性改变; 4.具有明确的临床诊断结局(包括诊断为结核性脑膜炎、疑似结核性脑膜炎或非结核性脑膜炎等),可作为评价依据; 5.脑脊液样本保存条件良好,信息完整,可用于核酸检测分析。

Inclusion criteria

1. Age >=18 years; underwent lumbar puncture during hospitalization with an archived, intact cerebrospinal fluid (CSF) specimen available. 2. Presence of clinical features suggestive of tuberculous meningitis (TBM), such as fever, headache, altered consciousness, neck stiffness, or cranial nerve deficits. 3. Neuroimaging (cranial CT/MRI) showing supportive changes, e.g., intracranial inflammatory lesions, meningeal enhancement, or hydrocephalus. 4. A definitive clinical diagnostic outcome is available (diagnosed TBM, suspected TBM, or non-TBM) to serve as the reference for evaluation. 5. CSF specimen adequately preserved with complete accompanying information, suitable for nucleic acid testing/analysis.

排除标准:

1.在入院前12个月内已接受过完整的潜伏性或活动性结核病抗结核治疗者; 2.在脑脊液样本采集前2周内接受过具有抗分枝杆菌活性的抗生素或抗结核药物(如利福平、异烟肼等),可能3.妊娠或哺乳期女性患者(出于生理状态特殊性考虑,排除该类人群); 4.确诊为播散性结核病或伴有HIV感染的多器官肺外结核患者,因其临床状态复杂、预后及免疫状态显著不同,可能干扰结果评价; 5.脑脊液样本或相关临床资料缺失、信息不完整,无法满足回顾性数据分析要求者; 6.研究者认为因样本质量不合格、污染或其他不符合检测条件的标本需排除者:

Exclusion criteria:

1. Received a full course of anti-tuberculosis therapy for latent or active TB within the 12 months prior to admission. 2. Received antibiotics with anti-mycobacterial activity or anti-TB drugs (e.g., rifampin/rifampicin, isoniazid) within 2 weeks before CSF collection, potentially affecting test results. 3. Pregnant or breastfeeding women, excluded due to special physiological considerations. 4. Patients with confirmed disseminated tuberculosis or extrapulmonary TB involving multiple organs with HIV co-infection, given the complexity of their clinical status and markedly different prognosis/immune state that could confound evaluation. 5. Missing or incomplete CSF specimens or related clinical data, insufficient for retrospective analysis. 6. Specimens deemed unacceptable by the investigators due to poor quality, contamination, or other conditions that do not meet testing requirements.

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):

Using the final clinical diagnosis and/or microbiological confirmation as the gold standard: a case is classified as tuberculous meningitis (TBM) if any of the following are met—(i) a final clinical diagnosis of TBM; (ii) a positive cerebrospinal fluid (CSF) Xpert MTB/RIF Ultra result; or (iii) a positive CSF culture for Mycobacterium tuberculosis complex (or a positive CSF acid-fast bacilli [AFB] smear).

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):

结核分枝杆菌复合群核酸检测试剂盒(荧光PCR法;全封闭微流控卡盒的一体化POCT方案)。 生物标志物/检测靶标:脑脊液中的结核分枝杆菌复合群(MTBC)DNA(多拷贝插入序列/保守基因位点)。 配套检测设备:Flash10全自动核酸检测分析仪(与集成化封闭卡盒配套,完成预处理—提取—扩增—检测,全流程约30分钟)。 前处理关键技术:非接触式侧壁超声裂解(用于提高CSF中低菌量样本的裂解与核酸富集效率)。

Assay/Kit: Mycobacterium tuberculosis complex (MTBC) nucleic acid test kit (fluorescent real-time PCR) using a fully enclosed, integrated microfluidic cartridge—point-of-care testing (POCT) format. Biomarker/Target: MTBC DNA in cerebrospinal fluid (CSF), targeting multi-copy insertion elements and conserved genomic loci. Companion Instrument: Flash10 fully automated nucleic acid testing analyzer (paired with the integrated closed cartridge; performs pre-processing → extraction → amplification → detection; total turnaround ≈30 minutes). Key Pre-analytical Technology: Non-contact side-wall ultrasonic lysis to enhance lysis and nucleic-acid enrichment in low-bacillary-load CSF specimens.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

本研究面向在参与中心因疑似中枢神经系统感染入院、住院期间行腰椎穿刺并留存脑脊液样本、且具有完整临床资料与最终诊断信息的成人患者(≥18 岁)。时间范围为 2020 年 1 月 1 日至 2024 年 6 月 30 日,样本均来源于常规诊疗过程中留存的既往标本。 为确保病例具有良好代表性并覆盖疾病全谱(case spectrum),纳入以下三类既往脑脊液标本: 1)经临床、影像学和/或病原学证实的结核性脑膜炎(TBM)患者; 2)具备 TBM 典型症状体征的疑似患者(部分可能缺乏明确病原学证据); 3)非结核性脑膜炎(如细菌性、病毒性、真菌性)或其他颅内疾病患者,作为鉴别对照人群。 疾病特征与纳入要点包括:出现发热、头痛、意识障碍、颈项强直、脑神经受累等临床表现,并有头颅 CT/MRI 提示颅内炎性病变、脑膜强化或脑积水等支持性影像学改变;所有对象均在住院期间完成腰穿并留存完整脑脊液样本。 代表性与分布:研究采用多中心竞争性入组,覆盖华北、东北、中部等区域的结核专科与传染病医院(北京胸科医院、沈阳市第十人民医院、河南省胸科医院、长春市传染病院),预计各中心病例比例约 40%/20%/20%/20%。计划总计分析 847 例疑似 TBM 的脑脊液标本,其中预计 TBM 确诊 402 例、非 TBM 445 例,以保证不同结局与病因在总体中的合理分布。

Sample size:

847

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Study population and time frame. Adults (>=18 years) admitted to participating centers for suspected central nervous system infection who underwent lumbar puncture during hospitalization, with archived cerebrospinal fluid (CSF) specimens and complete clinical records including a final diagnosis. The study window is 1 January 2020 to 30 June 2024; all specimens were archived remnants from routine clinical care. Case spectrum and specimen categories. To ensure representativeness and coverage of the full disease spectrum (case spectrum), three categories of archived CSF specimens will be included: 1. Patients with tuberculous meningitis (TBM) confirmed by clinical, imaging, and/or microbiological evidence; 2. Patients with typical TBM signs and symptoms (some lacking definitive microbiological proof) classified as suspected TBM; 3. Patients with non-TB meningitis (e.g., bacterial, viral, fungal) or other intracranial diseases, serving as a differential-diagnosis control cohort. Clinical features and imaging. Eligible cases typically present with fever, headache, altered consciousness, neck stiffness, or cranial nerve involvement, and have supportive neuroimaging on cranial CT/MRI indicating intracranial inflammatory lesions, meningeal enhancement, or hydrocephalus. All subjects underwent lumbar puncture during hospitalization with intact CSF archived. Representativeness and site distribution. A multicenter, competitively enrolled cohort spanning North, Northeast, and Central China TB/ID hospitals: Beijing Chest Hospital (), Shenyang Tenth People’s Hospital (), Henan Chest Hospital (), and Changchun Infectious Disease Hospital (). The anticipated case distribution across centers is ~40%/20%/20%/20%. Planned sample size.A total of 847 CSF specimens from patients with suspected TBM will be analyzed, with an expected composition of 402 confirmed TBM and 445 non-TBM cases, to ensure a balanced distribution of outcomes and etiologies.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

本研究的易混淆人群应来自“疑似中枢神经系统感染并已行腰穿留存CSF”的就诊人群,而非健康对照,主要包括:①其他感染性脑膜炎/脑炎——细菌性、病毒性、真菌性(如隐球菌)及亚急性感染(如布鲁菌、李斯特菌等);②非感染性但呈“类脑膜炎/类脑炎”表型——肿瘤性(癌性)脑膜炎、白血病/淋巴瘤中枢浸润;③免疫-炎症性疾病——结节病、系统性红斑狼疮相关脑膜炎、贝赫切特病、IgG4相关硬脑膜炎、中枢血管炎等;④其他可致脑膜刺激征或CSF异常的状态——术后/穿刺后反应性脑膜炎、蛛网膜下腔出血、脑静脉窦血栓等。上述人群用于构建非TBM对照,以体现真实的鉴别诊断情境并保证特异度评估的有效性。

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

The confounding population should be drawn from patients evaluated for suspected central nervous system (CNS) infection who have undergone lumbar puncture with archived CSF, rather than healthy controls. It primarily includes: 1.Other infectious meningitis/encephalitis—bacterial, viral, and fungal (e.g., cryptococcal), as well as subacute infections (e.g., Brucella, Listeria); 2. Non-infectious mimics with "meningitis/encephalitis-like" phenotypes—neoplastic (carcinomatous) meningitis and CNS infiltration by leukemia/lymphoma; 3. Immune-inflammatory disorders—sarcoidosis, systemic lupus erythematosus–associated meningitis, Beh?et disease, IgG4-related hypertrophic pachymeningitis, and primary CNS vasculitis; 4. Other conditions causing meningeal signs or CSF abnormalities—postoperative or post-lumbar-puncture reactive meningitis, subarachnoid hemorrhage, and cerebral venous sinus thrombosis.
