研究目的: |
一、主要目的 构建全国多中心大动脉炎累及肺动脉专病队列,开发并验证一个整合疾病活动度、肺血管形态学、右心功能及血清生物标志物的多模态预后模型,用于预测TAK-PAI患者的临床恶化风险(定义为:全因死亡、肺动脉高压危象、心功能恶化≥1级或需肺血管介入治疗)。 二、次要目的 1.识别关键预后因子 ① 量化评估CTPA特征(如狭窄部位数、肺段灌注缺损比例)与血流动力学参数(肺血管阻力PVR、心指数CI)的独立预测价值; ② 探索新型炎症标志物(IL-12/23、sCD25)及心肌损伤标记(NT-proBNP、GDF-15)对疾病进展的预警效能。 2.分析当前诊疗实践差异 ① 描述全国多中心TAK-PAI患者的基线管理策略(免疫抑制剂使用模式、PAH靶向药物选择、介入治疗时机); ② 评估治疗延迟(症状出现至干预时间)与血管不可逆重塑的相关性。 3.构建临床实用工具 ① 建立TAK-PAI专属风险分层评分(如0-10分制),指导个体化干预阈值划分。 |

Objectives of Study: |
Primary Objective To establish a nationwide multicenter dedicated cohort of Takayasu arteritis with pulmonary artery involvement (TAK-PAI), and to develop and validate a multimodal prognostic model integrating disease activity, pulmonary vascular morphology, right ventricular function, and serum biomarkers for predicting the risk of clinical deterioration in TAK-PAI patients—defined as all-cause mortality, pulmonary hypertension crisis, deterioration in cardiac function by ≥1 grade, or need for pulmonary vascular intervention. Secondary Objectives:1)Identify Key Prognostic Factors;2)Quantitatively evaluate the independent predictive value of CTPA characteristics (e.g., number of stenotic segments, proportion of perfused defective lung segments) and hemodynamic parameters (pulmonary vascular resistance [PVR], cardiac index [CI]).3)Explore the early warning efficacy of novel inflammatory markers (IL-12/23, sCD25) and myocardial injury markers (NT-proBNP, GDF-15) for disease progression.;4)Analyze Current Disparities in Clinical Practice;5)Describe baseline management strategies (patterns of immunosuppressant use, choices of PAH-targeted drugs, timing of interventional therapy) in TAK-PAI patients across multiple national centers.6)Evaluate the correlation between treatment delay (time from symptom onset to intervention) and irreversible vascular remodeling.7)Develop a Clinical Utility Tool;8)Establish a TAK-PAI-specific risk stratification score (e.g., 0–10 point scale) to guide individualized intervention thresholds. |

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: |
数据采集与记录(At Site)责任人员:研究者(PI/Sub-I) 是源数据准确性的第一责任人。研究协调员(CRC) 负责协助整理和转录。 ① 可归因(Attributable):所有源文件上的记录必须由执行者签名并签署日期(签名+日期),确保所有数据可追溯至产生者。 ② 及时(Contemporaneous):所有临床观察和活动需在发生后立即记录,严禁事后补记或追溯性修改。 ③ 清晰、持久(Legible, Enduring):使用不褪色的黑色签字笔书写,字迹清晰。电子记录需使用授权账户登录。 ④ 修改规范:任何错误的修改必须采用“划改”方式:单线划掉错误数据,在旁边书写正确数据,签名并注明日期,解释修改理由(如需要)。严禁使用涂改液覆盖或完全涂黑。 (2)数据录入(At Site → to eCRF) ① 责任人员:由经过授权的CRC负责将源数据转录至eCRF系统。 ② 要求: A.时限:数据需在访视结束后3个工作日内录入eCRF。 B.准确性:必须与源文件完全一致。 C.录入跟踪:eCRF系统将自动记录录入者身份、录入和修改时间戳,确保操作轨迹可追溯。 (3) 数据核对与质疑管理(Central) ① 责任人员:数据管理员(DM) 负责执行;CRC和研究者负责解答。 ② 核对制度: A.自动逻辑核查(Edit Checks):eCRF系统内预设程序化逻辑检查规则(如数值范围、跨表单逻辑矛盾、必填项缺失等),在数据录入时或定期运行,实时产生质疑(Query)。 B.人工审核:DM定期对数据进行人工审核,针对异常趋势、缺失数据、不一致信息等提出人工质疑。 ③ 质疑管理流程: ① 产生:DM在eCRF系统中发布质疑。 ② 通知:系统自动邮件通知CRC。 ③ 解答:CRC协同研究者查阅源文件,核实数据。 ④ 回复:在eCRF系统中对质疑进行回复: A.若数据无误,提供解释性说明。 B.若数据有误,直接修改数据并说明原因。 ⑤ 关闭:DM审核答复后关闭质疑。所有质疑及解答记录将被永久保存。 (4) 源数据核查(Source Data Verification, SDV) ① 责任人员:临床监查员(CRA)。 ② 制度:CRA定期到各中心,将eCRF中的数据与源文件进行比对核查,以确保数据转录的准确性。本研究计划对100%的主要终点数据和不低于10%的随机抽取的常规数据进行SDV。 (5) 数据锁定与归档 ① 责任人员:DM、统计师、PI。 ② 流程: A.数据库冻结:当所有数据录入完毕且质疑全部关闭后,DM冻结数据库,不再进行任何修改。 B.盲态审核:召开由PI、统计师、DM参加的盲态审核会,对冻结的数据进行最终审核,并决定是否锁定数据库。 C.数据库锁定:审核通过后,由DM、PI和统计师共同授权,正式锁定数据库。锁定后任何更改均需严格的《数据库解锁SOP》流程审批。 D.数据归档:锁定的数据库、所有eCRF数据、质疑记录、数据管理计划等,将以不可编辑的格式(如PDF, XPT)归档,长期保存至研究结束后至少5年。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection and Recording (At Site) Responsible Personnel: The Investigator (PI/Sub-I) is the primary responsible person for the accuracy of source data. The Clinical Research Coordinator (CRC) is responsible for assisting in organizing and transcribing the data. Attributable: All entries on source documents must be signed and dated (signature + date) by the person performing the activity, ensuring that all data can be traced back to the originator. Contemporaneous: All clinical observations and activities must be recorded immediately after they occur. Retrospective entries or modifications are strictly prohibited. Legible, Enduring: Use permanent black ink for written entries, ensuring clarity and readability. Electronic records must be created using authorized accounts. Modification Standards: Any errors must be corrected using the "single-line strike-through" method: draw a single line through the incorrect data, enter the correct data nearby, and sign and date the correction. A reason for the modification must be provided (if required). The use of correction fluid or complete blackout is strictly prohibited. (2) Data Entry (At Site → to eCRF) Responsible Personnel: Authorized CRCs are responsible for transcribing source data into the eCRF system. Requirements: A. Timeline: Data must be entered into the eCRF within 3 business days after the visit. B. Accuracy: The entered data must exactly match the source documents. C. Entry Tracking: The eCRF system will automatically record the identity of the person entering the data, along with timestamps for entry and modifications, ensuring a traceable operational trail. (3) Data Validation and Query Management (Central) Responsible Personnel: The Data Manager (DM) is responsible for execution; CRCs and Investigators are responsible for resolving queries. Validation System: A. Automated Logical Checks (Edit Checks): The eCRF system contains pre-programmed logical validation rules (e.g., value ranges, cross-form logical inconsistencies, mandatory field omissions) that run during data entry or periodically, generating real-time queries. B. Manual Review: The DM regularly performs manual reviews of the data and raises queries based on abnormal trends, missing data, inconsistencies, etc. Query Management Process: Generation: The DM issues queries within the eCRF system. Notification: The system automatically notifies the CRC via email. Resolution: The CRC collaborates with the Investigator to review source documents and verify the data. Response: Responses to queries are provided in the eCRF system: A. If the data are accurate, an explanatory note is provided. B. If an error is confirmed, the data are corrected and the reason is documented. Closure: The DM reviews the response and closes the query. All queries and resolutions are permanently archived. (4) Source Data Verification (SDV) Responsible Personnel: Clinical Research Associate (CRA). Procedure: The CRA periodically visits each site to compare data in the eCRF with source documents, ensuring accuracy in data transcription. This study plans to perform SDV on 100% of primary endpoint data and no less than 10% of routinely collected data selected at random. (5) Database Locking and Archiving Responsible Personnel: DM, Statistician, PI. Procedure: A. Database Freeze: Once all data are entered and all queries are resolved, the DM freezes the database, preventing any further modifications. B. Blinded Review: A blinded review meeting involving the PI, Statistician, and DM is held to conduct a final assessment of the frozen data and decide whether to lock the database. C. Database Lock: After approval, the database is officially locked upon joint authorization by the DM, PI, and Statistician. Any changes after locking require strict adherence to the "Database Unlocking SOP" process. D. Data Archiving: The locked database, all eCRF data, query records, data management plans, and other relevant documents are archived in non-editable formats (e.g., PDF, XPT) and retained for at least 5 years after the study concludes. |
