The introduction of nucleot(s)ide analogues (NAs) for oral antiviral therapy has dramatically improved the clinical outcome of patients with chronic hepatitis B. NAs appear to be safe and induce potent suppression of viral replication. However, they are associated with a low rate of HBsAg seroclearance, the gold standard of successful treatment, and also with a relatively high rate of virological relapse after discontinuation. As a result, long-term treatment is needed. The optimal duration of NA treatment currently remains unclear, nevertheless in some patients NA treatment can be stopped with a relatively low probability of relapse. Whether NAs are able to induce a sustained off-treatment response is an important area for research. This article reviews the relapse rate after cessation of treatment with NAs in chronic hepatitis B patients with the goal of identifying possible predictive factors of relapse.
核苷酸类似物(NAs)用于口服抗病毒治疗显著改善了慢性乙型肝炎患者的临床结局。NAs似乎安全且能有效抑制病毒复制。然而,它们与成功治疗的金标准——HBsAg血清学清除率较低相关,且停药后病毒学复发率相对较高。因此,需要进行长期治疗。目前NA治疗的最佳疗程仍不清楚,不过在一些患者中,NA治疗停药后复发概率相对较低。NAs是否能够诱导持续的停药后反应是一个重要的研究领域。本文回顾了慢性乙型肝炎患者停用NA治疗后的复发率,目的是确定可能的复发预测因素。
