| 中文摘要: |
| 慢性乙型肝炎（chronic hepatitis B, CHB）是一种广泛的全球性感染性疾病，可以发展为肝硬化甚至肝细胞癌。聚乙二醇化干扰素α和核苷（酸）类似物等治疗药物可以抑制HBV，延缓CHB患者的疾病进展，但部分患者经强效低耐药药物治疗后仍不能获得有效的病毒学应答，而持续存在的低水平病毒血症可以诱发耐药、促进肝纤维化进展、增加肝细胞癌发生风险，严重影响患者预后。明确低水平病毒血症的危害，探索阐明其发生机制，从而辅助调整个体化治疗方案，是目前的研究热点及难点。本文就低水平病毒血症相关的病因、危害及治疗等方面的研究进展进行阐述，以期为该类患者的诊疗提供参考。 |
| 英文摘要: |
| Chronic hepatitis B (CHB) is a widespread global infectious disease that can develop into liver cirrhosis and even hepatocellular carcinoma. Therapeutic drugs such as pegylated interferon alpha and nucleo(s)tide analogs can inhibit HBV and delay the disease progression of CHB patients. However, some patients still cannot obtain an effective virological response after being treated with strong and low-drug-resistant drugs. Persistent low-level viremia can induce drug resistance, promote the progression of liver fibrosis, increase the risk of hepatocellular carcinoma and seriously affect the prognosis of patients. Clarifying the harm of low-level viremia and exploring the pathogenesis to assist in the adjustment of individualized treatment plans are current research hotspots and difficulties. This article aims to describe the research progress of low-level viremia-related etiology, harm and treatment, in order to provide reference for the diagnosis and treatment of these patients. |
