研究目的:

光子晶体芯片检测法和化学发光法作为新兴的分析技术,可能成为替代传统他克莫司浓度监测方法的候选方案。因此,研究的目的是比较光子晶体芯片检测法和化学发光法在检测他克莫司浓度方面的性能差异,并评估它们在临床实践中的应用潜力。利用光子晶体纳米材料放大荧光信号的特点,希望开发一种检测他克莫司浓度的方法,便于移植受者床旁、居家检测。  

Objectives of Study:

Photonics crystal chip detection method and chemiluminescence assay, as emerging analytical technologies, may serve as alternative options to traditional methods for monitoring tacrolimus concentration. Therefore, the aim of the study is to compare the performance differences between the photonics crystal chip detection method and chemiluminescence assay in detecting tacrolimus concentration and evaluate their potential applications in clinical practice. By leveraging the fluorescence signal amplification characteristics of photonics crystal nanomaterials, the goal is to develop a method for detecting tacrolimus concentration that is suitable for bedside and home testing in transplant recipients.

诊断试验:

Diagnostic Tests:

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):

金标准或参考标准是临床常用的化学发光法检测普乐可复血药浓度。普乐可复(他克莫司)测定试剂盒(化学发光微粒子免疫检测法,CMIA)由雅培(ARCHITECT)制造商生产,采用化学发光微粒子免疫检测法,通过特异性抗体与他克莫司结合形成免疫复合物,利用化学发光信号定量检测血药浓度。其检测范围为1.0-30.0 ng/mL,灵敏度低于1.0 ng/mL,精密度高(批内CV <5%,批间CV <10%),特异性强,与LC-MS/MS结果相关性良好(R² >0.95)。适用于EDTA抗凝全血样本,主要用于器官移植患者的他克莫司血药浓度监测,以指导用药剂量调整,预防药物毒性或排斥反应。该试剂盒已获国家药品监督管理局(NMPA)批准。

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):

The gold standard or reference standard is the clinically commonly used chemiluminescence method for detecting the blood concentration of Prograf. The Prograf assay kit (chemiluminescent microparticle immunoassay, CMIA) is manufactured by Abbott (ARCHITECT) and utilizes the chemiluminescent microparticle immunoassay method. It forms immune complexes by binding tacrolimus with specific antibodies and quantifies the blood concentration through chemiluminescent signals. The detection range is 1.0-30.0 ng/mL, with a sensitivity of less than 1.0 ng/mL, high precision (intra-assay CV <5%, inter-assay CV <10%), strong specificity, and excellent correlation with LC-MS/MS results (R² >0.95). It is suitable for EDTA-anticoagulated whole blood samples and is primarily used for monitoring tacrolimus blood concentrations in organ transplant patients to guide dosage adjustments and prevent drug toxicity or rejection reactions. This kit has been approved by the National Medical Products Administration (NMPA).

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):

指标试验采用光子晶体芯片检测法,其主要原理是基于光的散射和干涉效应,通过调控晶格结构和材料的折射率,实现对特定光波的选择性散射,从而实现对物质浓度的检测。

Index test:

The index test employs the photonic crystal chip detection method, the primary principle of which is based on the scattering and interference effects of light. By modulating the lattice structure and the refractive index of the material, selective scattering of specific light wavelengths is achieved, thereby enabling the detection of substance concentrations.

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)

1.目标人群是器官移植(肝或肾移植)术后接受他克莫司治疗的特定疾病患者群体。 2.具体的疾病特征包括:(1)疾病类型:器官移植(肝或肾移植)后的免疫抑制治疗。(2)疾病特点:器官移植后由于免疫系统被抑制,需要长期使用他克莫司以防止器官排斥反应。(3)全序列病例:研究应纳入符合目标人群分布特点的全序列病例,即包括不同年龄、性别、移植器官类型和治疗时间等方面的患者。

例数:

Sample size:

80

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):

The target population is a specific group of patients who have undergone organ transplantation (liver or kidney) and are receiving tacrolimus treatment post-transplantation. Specific disease characteristics include: (1) Disease type: Immunosuppressive therapy following organ transplantation (liver or kidney). (2) Disease features: Due to immune system suppression after organ transplantation, long-term use of tacrolimus is required to prevent organ rejection. (3) Full sequence cases: The study should include a full sequence of cases that meet the distribution characteristics of the target population, including patients of different ages, genders, types of transplanted organs, and treatment durations.

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):

1.其他免疫抑制治疗患者:如接受环孢素、雷帕霉素等其他免疫抑制剂治疗的患者,其血药浓度监测和临床表现可能与接受他克莫司治疗的患者相似。2.自身免疫性疾病患者:如系统性红斑狼疮、类风湿性关节炎等,这些疾病可能需要类似的免疫抑制治疗,但其病因和治疗目标与器官移植患者不同。3.慢性肝病或肾病患者:未进行器官移植但患有慢性肝病或肾病的患者,其临床表现和实验室检测结果可能与移植患者相似。4.感染性疾病患者:某些感染性疾病(如巨细胞病毒感染、EB病毒感染)可能导致类似免疫抑制状态或器官功能异常,容易被误认为是移植相关并发症。

例数:

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:

1. Patients receiving other immunosuppressive therapies: For example, patients treated with immunosuppressants such as cyclosporine or rapamycin may have similar blood concentration monitoring and clinical manifestations to those receiving tacrolimus therapy. 2. Patients with autoimmune diseases: Conditions such as systemic lupus erythematosus and rheumatoid arthritis may require similar immunosuppressive treatments, but their etiology and treatment goals differ from those of organ transplant patients. 3. Patients with chronic liver or kidney disease: Those who have chronic liver or kidney disease but have not undergone organ transplantation may exhibit clinical manifestations and laboratory test results similar to transplant patients. 4. Patients with infectious diseases: Certain infectious diseases (cytomegalovirus infection, EB virus infection) may lead to a similar immunosuppressed state or organ dysfunction, which can easily be mistaken for transplant-related complications.

In comparative studies, an EDC system (such as ResMan) can be used to collect and manage data. The following are some functionalities and benefits of an EDC system: (1) Data input interface: Provides a user-friendly interface for data collection personnel to conveniently input data. (2) Data validation and logic checks: The EDC system can perform data validation and logic checks to ensure data accuracy and completeness. (3) Data storage and backup: The EDC system provides secure data storage and backup functions to prevent data loss or damage. (4) Data access control: The EDC system can set data access permissions for different users to ensure data security. (5) Data export and analysis: The EDC system allows data to be exported in standard formats for subsequent statistical analysis and report generation.
