研究目的:

隐匿性乙型感染病毒感染(OBI)是HBV感染后的一种特殊状态,而目前OBI却存在难发现、无治疗方案、易隐匿进展和恶化等难题。理清OBI的疾病动态变化为OBI的早发现、早诊断和早治疗奠定了重要的基础。OBI感染者肝细胞内HBV往往处于低复制水平,血浆中HBsAg阴性且HBV DNA呈波动性检出,为OBI的及时发现和诊断带来了巨大挑战,急需一些新的标志物来帮助实现感染者的有效甄别和及时治疗。本研究中,拟利用本课题组在既往研究中已建立的我国献血者人群中隐匿性乙型肝炎病毒感染队列和慢性乙型肝炎病毒感染队列,计划分别纳入隐匿性乙型肝炎病毒感染者与慢性乙型肝炎病毒感染者各90-100名,利用经过2年多次随访的血液样本对HBV经典标志物及HBV新型标志物进行检测及分析,一方面通过建立适用于实验室日常检测的大体积血浆HBV核酸超灵敏检测方法,另一方面探讨HBV新型标志物(超敏HBsAg、HBcrAg和HBV pgRNA等)对于OBI感染状态和临床应用的价值,为OBI的早发现、早诊断和早治疗提供数据基础。  

Objectives of Study:

Occult hepatitis B virus infection is a special state after HBV infection, but currently OBI faces challenges such as difficulty in detection, lack of treatment options, and susceptibility to hidden progression and deterioration. Clarifying the dynamic changes of OBI diseases lays an important foundation for early detection, diagnosis, and treatment of OBI. The HBV in the liver cells of OBI-infected individuals is often at a low replication level, with HBsAg negative in plasma and fluctuating detection of HBV DNA, which poses a huge challenge for the timely detection and diagnosis of OBI. New biomarkers are urgently needed to help achieve effective identification and timely treatment of infected individuals. In this study, we plan to use the OBI and chronic hepatitis B virus infection queue established in previous studies among blood donors in China. 90-100 OBI and chronic hepatitis B virus infections will be included respectively. We will use blood samples that have been followed up for more than 2 years to detect and analyze classic and novel HBV markers. On the one hand, we will establish a high-sensitivity detection method for large-volume plasma HBV nucleic acid suitable for laboratory daily testing. On the other hand, we will explore the value of novel HBV markers (such as ultra-sensitive HBsAg, HBcrAg, and HBV pgRNA) for the status and clinical application of OBI infection, to provide early detection, early diagnosis, and early detection of OBI.

Barcodes are uniformly written by the clinical testing center for sample testing. Only the blood donation code can be directly traced back to the blood donor in the data information, but the corresponding donor identity information cannot be directly obtained by the clinical testing center. The identity information is only stored in each participating unit and strictly confidential.
