经核苷(酸)类药物治疗的慢性乙型肝炎HBsAg定量分析

目的总结分析慢性乙型肝炎(CHB)患者使用核苷(酸)类药物(NAs)进行抗病毒治疗后,HBsAg水平的动态变化规律。方法回顾性收集2012年7月30日至2016年12月30日在北京协和医院进行血清乙型肝炎表面抗原定量(qHBsAg)检测的CHB患者资料,分析随访192周过程中每24周的qHBsAg、HBV DNA和HBeAg的数据。采用化学发光微粒子免疫分析法检测qHBsAg和HBeAg,采用PCR和COBAS Amplicor检测HBV DNA。结果共纳入60例患者,HBeAg阳性组基线HBV DNA高于阴性组(P0.05),在48周后均降至检测下限以下。HBeAg阳性组与HBeAg阴性组基线qHBsAg分别为(3.43±0.73)log_(10)IU/m L,(3.08±0.47)log_(10)IU/m L。除48周外,所有随访时间点HBeAg阳性组qHBsAg均高于HBeAg阴性组(P0.05)。HBeAg阳性组在抗病毒治疗后,HBeAg定量有显著下降(P0.05)。结论 CHB患者在接受长期NAs治疗过程中,实现HBsAg转阴这一临床治愈目标较为困难,长期应用NAs治疗十分必要。

Kinetics of serum HBsAg in chronichepatitis B patients with nucleos(t)ide analogues treatment

Objective To summarize and analyze the dynamic change of HBsAg levels in patients with chronic Hepatitis B (CHB) after receiving nucleos(t)ide analogues (NAs) as antiviral treatment.Methods Patients who were performed quantitative Hepatitis B surface antigen(qHBsAg) from July 30, 2012 to December 30,2016 in Peking Union Medical College Hospital were retrospectively enrolled.qHBsAg, HBV DNA, HBeAg were collected and analyzed at baseline and at 192-week follow-up every 24 weeks.qHBsAg and HBeAg were assessed with chemiluminesent microparticle immuno assay(CMIA).HBV DNA was assessed with PCR and COBAS Amplicor.Results 60 patients were included.Patients in HBeAg-positive group had higher HBV DNA than that in HBeAg-negative group (P<0.05)at baseline and the two groups both were under detection limit after 48 weeks.BaselineqHBsAg in HBeAg positive-group and negative-group were (3.43±0.73) log10 IU/mL, (3.08±0.47) log10 IU/mL respectively.qHBsAg in HBeAg-positive group was higher than that in HBeAg negative-group on all follow-ups(P<0.05) except 48weeks.However on 168 weeks and 192 weeks, difference between the two groups was statistically significant(P<0.05).In HBeAg-positive group,quantitative HBeAg dropped significantly during antiviral treatment.Conclusions HBV replication can be suppressed in the process of long-term NAs treatment in CHB patients.However qHBsAg decline is not so obvious, which indicates that HBsAg cleavence is difficult,and long-term NAs therapy is still necessary.
