研究目的:

通过包含 QSM、pCASL 和 BOLD 在内的多模态 MRI 肾脏功能成像后纹理特征的提取,从肾脏纤维化、血流、氧合等特征综合评估 S3b、S4 期肾功能衰竭失代偿 CKD 患者皮、髓质功能衰竭的程度,结合临床资料及实验室检查结果,通过受试者随访 2 年有无不良结局进行分组,建立不良结局的风险预测模型和列线图,弥补实验室检查不能具体、直观反映肾脏硬度、血流或氧合等功能的不足,从而达到风险评估、疾病预防和精准治疗的目的。  

Objectives of Study:

Through the extraction of texture features from multi-modal MRI renal functional imaging, including QSM (Quantitative Susceptibility Mapping), pCASL (Pseudo-Continuous Arterial Spin Labeling), and BOLD (Blood Oxygen Level-Dependent), this study comprehensively evaluates the degree of cortical and medullary functional impairment in S3b and S4 stage decompensated CKD patients with renal failure. The assessment is based on characteristics such as renal fibrosis, blood flow, and oxygenation. By integrating clinical data and laboratory test results, patients are grouped according to the presence or absence of adverse outcomes during a 2-year follow-up period. A risk prediction model and nomogram for adverse outcomes are established to address the limitations of laboratory tests, which cannot specifically and intuitively reflect renal functions such as stiffness, blood flow, or oxygenation. This approach aims to achieve risk assessment, disease prevention, and precise treatment.

纳入标准:

根据“肾脏疾病预后质量倡议”的临床实践指南制定诊断标准和分期。纳入15 mL/min/1.73m2 <= sCr-eGFR < 45 mL/min/1.73m2 CKD患者。sCr-eGFR由以下公式计算:eGFR = 194 × 血清肌酐?1.??? × 年龄??.2??(如果是女性,×0.739)。在入组时,通过阅读文献、临床经验以及我们先前的研究获得的数据来建立候选因变量的范围,包括年龄、性别、SBP/DBP、sCr(或cyc-s)-eGFR、血红蛋白、电解质钾、有无糖尿病、CKD分期、影像学指标(血流、氧耗、磁化率)等。通过检测血液和尿液样本来收集生化变量指标。

Inclusion criteria

Diagnostic criteria and staging were developed according to the clinical practice guidelines of the Kidney Disease Prognostic Quality Initiative. Patients with 15 mL/min/1.73 m2 <= sCr-eGFR < 45 mL/min/1.73 m2 CKD were included. sCr-eGFR was calculated by the following formula: eGFR = 194 × serum creatinine?1.??? × age??.2?? (× 0.739 if female). At the time of enrollment, a range of candidate dependent variables was established by reading the literature, clinical experience, and data obtained from our previous studies, including age, sex, SBP/DBP, sCr (or cyc-s)-eGFR, hemoglobin, electrolyte potassium, presence or absence of diabetes mellitus, CKD stage, imaging parameters (blood flow, oxygen consumption, magnetic susceptibility), etc. Indicators of biochemical variables are collected by testing blood and urine samples.

排除标准:

1、CKD患者的急性肾损伤、肾动脉狭窄、肾透析治疗、双肾较大的占位性病变(长轴径 >= 20 mm)、一侧肾脏切除、恶性肿瘤、心功能不全、肝硬化和腹水。 2、磁共振扫描前3天内用抗凝抗栓类药(拜阿司匹林、波立维等)和利尿剂的患者以及自发现肾功能异常后拒绝医学干预或治疗的患者。 3、MRI禁忌症(如扫描区域的金属伪影、幽闭恐惧症、怀孕、年龄 < 18岁或 > 70岁)的患者也被排除在外。

Exclusion criteria:

1. Acute kidney injury, renal artery stenosis, renal dialysis treatment, large space-occupying lesions of both kidneys (long axis diameter >= 20 mm), nephrectomy on one side, malignant tumors, cardiac insufficiency, liver cirrhosis and ascites. 2. Patients who have taken anticoagulant and antithrombotic drugs (aspirin, Plavix, etc.) and diuretics within 3 days before the MRI scan, and patients who refuse medical intervention or treatment since the discovery of abnormal renal function. 3. Patients with contraindications to MRI (such as metal artifacts in the scanning area, claustrophobia, pregnancy, age < 18 years or > 70 years) are also excluded.

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

根据 “肾脏疾病预后质量倡议”的临床实践指南制定诊断标准和分期。根据 sCr-eGFR 值≥90、60-90、45-60、30-45、15-30,和 <15 mL/min/1.73 m2将 CKD 分成 5 期(S1、S2、S3、S4、S5),其中将 S3 分成 a、b 两个亚期,即 S3a 为 45-60 mL/min/1.73 m2、S3b为 30-45 mL/min/1.73 m2,

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):

According to the clinical practice guidelines of the "Kidney Disease Outcomes Quality Initiative (KDOQI)", the diagnostic criteria and staging of Chronic Kidney Disease (CKD) are established. Based on sCr-eGFR values of ≥90, 60-90, 45-60, 30-45, 15-30, and <15 mL/min/1.73 m2, CKD is divided into 5 stages (S1, S2, S3, S4, S5). The S3 stage is further subdivided into two sub-stages: S3a (45-60 mL/min/1.73 m2) and S3b(30-45 mL/min/1.73 m2).
