研究目的: |
1.主要目的 定量评估儿童原发性肾病综合征(PNS)在不同临床状态(初发未治、活动期/复发、完全缓解)下肾皮质剪切波弹性成像(SWE)硬度值与超微血管成像(SMI)血流参数,并与年龄、性别相匹配的健康儿童进行对照比较。 探讨肾皮质SWE硬度值及SMI血流参数与PNS患儿关键临床指标(24小时尿蛋白定量、血清白蛋白、血脂、估算肾小球滤过率等)之间的相关性。 动态观察PNS患儿在糖皮质激素治疗前后及病程复发-缓解过程中,肾皮质SWE硬度值与SMI血流参数的纵向变化规律。 2.次要目的 分析不同病理类型(如微小病变MCD vs. 局灶节段性肾小球硬化FSGS,基于肾活检结果)的PNS患儿肾皮质SWE硬度值与SMI血流参数是否存在差异。 探索肾皮质SWE硬度值与SMI血流参数对PNS患儿糖皮质激素治疗反应性(激素敏感 vs. 激素抵抗)的早期预测价值。 初步建立本中心健康儿童及PNS患儿肾皮质SWE硬度与SMI血流的参考值范围(如适用)。 评估联合应用SWE与SMI参数,构建无创预测模型,用于鉴别PNS病理类型或预测预后的可行性。 |

Objectives of Study: |
1. Main purpose Quantitatively evaluate the renal cortex shear wave elastography (SWE) stiffness values and super microvascular imaging (SMI) blood flow parameters in children with primary nephrotic syndrome (PNS) under different clinical states (initial untreated, active/relapsed, complete remission), and compare them with age- and gender-matched healthy children. Explore the correlation between renal cortical SWE stiffness values and SMI blood flow parameters and key clinical indicators in children with PNS (24-hour urine protein quantitation, serum albumin, blood lipids, estimated glomerular filtration rate, etc.). Dynamically observe the longitudinal changes in SWE stiffness values and SMI blood flow parameters in the renal cortex of children with PNS before and after glucocorticoid treatment, as well as during the disease's relapse-remission process. 2. Secondary objectives Analyze whether there are differences in SWE stiffness values and SMI blood flow parameters in the renal cortex of children with PNS based on renal biopsy results, considering different pathological types such as minimal change disease (MCD) versus focal segmental glomerulosclerosis (FSGS). Explore the early predictive value of renal cortical SWE stiffness values and SMI blood flow parameters for the response to glucocorticoid treatment (hormone-sensitive vs. hormone-resistant) in children with PNS. Preliminarily establish the reference range for SWE stiffness and SMI blood flow in the renal cortex of healthy children and children with PNS in our center (if applicable). Evaluate the feasibility of combining SWE and SMI parameters to construct a non-invasive prediction model for identifying the pathological type of PNS or predicting prognosis. |

Exclusion criteria: |
Exclusion Criteria for Pediatric PNS Patients 1. Secondary nephrotic syndrome (e.g., lupus nephritis, Henoch-Schönlein purpura nephritis, hepatitis B virus-associated nephritis, etc.). 2. Congenital nephrotic syndrome. 3. Presence of other known severe systemic diseases that may affect kidney stiffness or blood flow (e.g., congenital heart disease, severe liver disease, connective tissue disease, etc.). 4. Concurrent acute kidney injury (AKI, according to KDIGO criteria) or stage 3 or higher chronic kidney disease (CKD) (eGFR < 60 ml/min/1.73m²). 5. Absolute contraindications to ultrasound examination (e.g., severe skin damage or infection in the examination area). 6. Unable to cooperate with ultrasound examination (e.g., severe crying, unable to maintain necessary positions or breath-holding). 7. Any other condition deemed unsuitable for participation in this study by the investigator. Exclusion Criteria for Healthy Control Group: Same as items 3, 5, 6, and 7 in the exclusion criteria for PNS patients. |

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: |
病例报告表(CRF)设计: 设计标准化的电子病例报告表(e-CRF),涵盖所有需要收集的临床、实验室和影像学数据。e-CRF将部署在安全的中央化电子数据采集系统(如REDCap)中,设置逻辑核查和数值范围核查,从源头减少错误。 数据录入: 设立专职数据管理员,或由经过培训的研究协调员,在数据产生后尽快录入e-CRF。对关键数据(如主要结局指标)实行双人独立录入与核对。 数据库建立与维护: 建立专用的研究数据库。定期备份数据库,确保数据安全。 数据匿名化: 所有收集的数据将使用唯一的研究ID进行标识,去除所有能直接识别患者身份的信息(姓名、身份证号、住院号等)。研究ID与患者身份的对应关系(“密钥”)将由主要研究者单独加密保存,与分析数据分离。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Case Report Form (CRF) design: Design a standardized electronic case report form (e-CRF) that encompasses all necessary clinical, laboratory, and imaging data to be collected. The e-CRF will be hosted on a secure, centralized electronic data capture system (such as REDCap), equipped with logical and numerical range checks to minimize errors at the source. Data entry: Appoint a dedicated data administrator, or alternatively, a trained research coordinator, to enter data into the e-CRF as soon as it is generated. For critical data (such as primary outcome measures), implement a system of independent entry and verification by two individuals. Database establishment and maintenance: Establish a dedicated research database. Regularly back up the database to ensure data security. Data anonymization: All collected data will be identified using a unique study ID, with all information that can directly identify the patient (such as name, ID number, hospitalization number, etc.) removed. The correspondence between the study ID and patient identity ("key") will be encrypted and stored separately by the principal investigator, independent of the analysis data. |
