摘要:
目的 分析血清血管生成素(Ang)1、2及其比值变化与慢性乙型肝炎(CHB)、肝硬化患者HBV DNA和ALT的相关性。 方法 选取2018年3月—2019年10月首都医科大学附属北京佑安医院收治的CHB患者99例,肝硬化患者59例,收集临床资料和血清标本;另选同期46例健康体检者作为对照组。所有患者均采用PCR法检测血清HBV DNA;采用酶联免疫吸附法检测血清Ang-1和Ang-2水平,比较各组血清Ang-1和Ang-2及Ang-1/Ang-2的差异。非正态分布的计量资料多组间比较采用Kruskal-Wallis H检验,进一步两两比较采用Bonferroni法;采用Spearman方法分析Ang-1、Ang-2、Ang-1/Ang-2与HBV DNA、ALT的相关性。 结果 与对照组(671.0 pg/mL)相比,CHB组(479.0 pg/mL)和肝硬化组(208.4 pg/mL)Ang-1水平显著降低(P值均<0.05);与CHB组相比,肝硬化组Ang-1水平显著降低(P<0.001)。与对照组(198.0 pg/mL)相比,CHB组(286.1 pg/mL)和肝硬化组(438.4 pg/mL)Ang-2水平显著升高(P值均<0.001);与CHB组相比,肝硬化组Ang-2水平显著升高(P<0.001)。与对照组(3.4)相比,CHB组(1.6)和肝硬化组(0.5)Ang-1/Ang-2比值显著降低(P值均<0.001);与CHB组相比,肝硬化组Ang-1/Ang-2比值显著降低(P<0.001)。Spearman分析显示,CHB组Ang-1与HBV DNA及ALT均呈负相关(r值分别为-0.400、-0.394,P值均˂0.001);Ang-2与HBV DNA及ALT均呈正相关(r值分别为0.365、0.351,P值均˂0.001);Ang-1/Ang-2与HBV DNA及ALT均呈负相关(r值分别为-0.463、-0.473,P值均˂0.001);而肝硬化组Ang-1、Ang-2及Ang-1/Ang-2均与HBV DNA和ALT无相关性(P值均˃0.05)。 结论 CHB、肝硬化患者血清Ang-1、Ang-2及Ang-1/Ang-2有显著改变,其中肝炎组Ang-1、Ang-2及Ang-1/Ang-2在一定程度上反映CHB患者肝损伤的程度。 Abstract:Objective To investigate the correlation of serum angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), and Ang-1/Ang-2 ratio with HBA DNA and alanine aminotransferase (ALT) in patients with chronic hepatitis B (CHB) or liver cirrhosis. Methods Clinical data and serum specimens were collected from 99 patients with CHB and 59 patients with liver cirrhosis who were admitted to Beijing YouAn Hospital, Capital Medical University, from March 2018 to October 2019, and 46 individuals who underwent physical examination were enrolled as control group. PCR was used to measure serum HBV DNA level, and ELISA was used to measure the serum levels of Ang-1 and Ang-2. The serum levels of Ang-1 and Ang-2 and Ang-1/Ang-2 ratio were compared between groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Bonferroni method was used for further comparison between two groups; the Spearman correlation analysis was used to investigate the correlation of Ang-1, Ang-2, and Ang-1/Ang-2 ratio with HBV DNA and ALT. Results Compared with the control group, the CHB group and the liver cirrhosis group had a significant reduction in the level of Ang-1 (479.0 pg/mL and 208.4 pg/mL vs 671.0 pg/mL, both P<0.05), and compared with the CHB group, the liver cirrhosis group had a significant reduction in the level of Ang-1 (P<0.001). Compared with the control group, the CHB group and the liver cirrhosis group had a significant increase in the level of Ang-2 (286.1 pg/mL and 438.4 pg/mL vs 198.0 pg/mL, both P<0.001), and compared with the CHB group, the liver cirrhosis group had a significant increase in the level of Ang-2 (P<0.001). Compared with the control group, the CHB group and the liver cirrhosis group had a significant reduction in Ang-1/Ang-2 ratio (1.6 and 0.5 vs 3.4, both P<0.001), and compared with the CHB group, the liver cirrhosis group had a significant reduction in Ang-1/Ang-2 ratio (P<0.001). The Spearman correlation analysis showed that in the CHB group, Ang-1 was negatively correlated with HBV DNA and ALT (r=-0.400 and -0.394, both P˂0.001), Ang-2 was positively correlated with HBV DNA and ALT (r=0.365 and 0.351, both P<0.001), and Ang-1/Ang-2 ratio was negatively correlated with HBV DNA and ALT (r=-0.463 and -0.473, both P<0.001); in the liver cirrhosis group, Ang-1, Ang-2, and Ang-1/Ang-2 ratio had no correlation with HBV DNA or ALT (all P>0.05). Conclusion There are significant changes in the serum levels of Ang-1 and Ang-2 and Ang-1/Ang-2 ratio in patients with CHB or liver cirrhosis, and Ang-1, Ang-2, and Ang-1/Ang-2 ratio reflects the degree of liver injury in patients with CHB to a certain extent. -

抗病毒治疗是慢性乙型肝炎(CHB)的关键措施,其中恩替卡韦(ETV) 是治疗HBV的一线核苷(酸)类似物(NAs) 之一。尽管其他研究曾报道了长期ETV治疗CHB的疗效和安全性,但其在中国慢性CHB(主要为基因型B和C)患者中的临床数据仍然有限。
马来酸ETV是正大天晴药业股份有限公司开发的ETV衍生物,多中心、随机、双盲双模拟、阳性药物对照临床研究显示其治疗48周时与原研ETV在治疗CHB时等效,基于上述结果,国家食品药品管理局已经批准其上市。作为此项研究的主要研究者,北京大学第一医院于岩岩教授对其长期疗效和安全性进行了进一步研究:此前已经报告144周的马来酸ETV治疗中国慢性CHB(主要为基因型B和C)患者有效而且安全。更长疗程的药物治疗效果和安全性如何,尚无知晓。
2022年7月6日于岩岩教授团队在线发表研究论文,旨在更新马来酸ETV治疗中国患者240周疗程的病毒学、血清学和生化结果。CHB受试者被随机分配接受0.5 mg/d ETV(A组)或0.5 mg/d马来酸ETV(B组)治疗48周,此后所有受试者从第49周开始接受0.5 mg/d马来酸ETV治疗。定期对患者进行随访,监测血清HBV标志物、肝生化等指标,记录不良事件(AE)。主要终点是治疗结束时每组HBV DNA的下降。次要终点包括治疗结束时HBV DNA不可测(<20 IU/mL) 的比率、HBeAg消失率、HBeAg血清转化率和血清ALT复常率。137例(A组71例) HBeAg阳性CHB患者和46例(A组21例)HBeAg阴性CHB患者完成了240周的治疗和随访。两组的基线特征可比。在HBeAg阳性CHB组,240周时两组的HBV DNA较基线下降平均值可比(A:6.67 log10 IU/mL vs B:6.74 log10 IU/mL;P>0.05),血清HBV DNA不可测率(A:91.55% vs B:87.88%;P>0.05)、HBeAg血清学转换率(A:26.98% vs B:20.97%;P>0.05)和ALT复常率(A:87.32% vs B:83.61%;P>0.05)均在组间可比。在HBeAg阴性CHB组,240周时两组的HBV DNA较基线下降平均值可比(A:6.05 log10 IU/mL vs B:6.10 log10 IU/mL;P>0.05),血清HBV DNA不可测比例(A:100% vs B:100%)和ALT复常率(A:90.91% vs B:95.45%)(P>0.05)也可比。在耐药方面,HBeAg阴性CHB组耐药率为0;HBeAg阳性CHB组144周时耐药率1.16%,此后直至240周新增1例ETV耐药。安全性方面,没有因为AE导致停药,无肝癌或死亡病例。
总之,作为国产抗HBV药物代表之一的马来酸ETV,长期治疗中国CHB(主要是基因型B或C)是安全有效的。
