Description for medicine or protocol of treatment in detail:

 

纳入标准:

恩替卡韦疗效组:回顾性纳入于我院确诊为慢性乙型病毒性肝炎的患儿,根据其接受恩替卡韦抗病毒治疗48周时,是否出现 HBeAg 转阴、HBV DNA低于 2000IU/mL且ALT复常,分为应答组及非应答组。 横向人群:包括IT期,IA期以及CR期。IT 期定义为HBeAg 阳性、高病毒载量(HBV DNA>2×10^7IU/ml),且谷丙转氨酶(alanine transaminase, ALT)持续正常或轻微升高(<1.5 倍正常值上限(upper limits of normal, ULN);IA 期定义为 HBeAg 阳性,HBV DNA>2×104IU/ml,且 ALT≥1.5 倍 ULN;联合应答(combined response, CR) 定义为接受抗病毒治疗后,出现HBeAg转阴、HBV DNA低于2000IU/mL且ALT复常。 纵向人群:HBsAg或HBV DNA阳性持续6个月以上,于我院初诊为慢乙肝并接受恩替卡韦治疗且完成至少48周规律治疗随访。

Inclusion criteria

Entecavir group:Children with chronic type B hepatitis were included retrospectively. According to the therapeutic effect in 48 weeks, the responders defined as the lack of serum HBeAg, low or undetectable HBV DNA levels ( <2000IU/ml ) and ALT normalization after receiving antiviral therapy. Horizontal group:We enrolled children with hepatitis B infection, including immune tolerant ( IT ) phase, imunne active ( IA ) phase and combined response ( CR ) phase. In this study,IT phase, recurrently HBeAg-positive chronic HBV infection; defined as HBV DNA>10^7 IU/ml, alanine aminotransferase ( ALT ) consistently within the normal range . Imunne active ( IA ) phase, recurrently HBeAg-positive chronic hepatitis B, is characterised by the presence of serum HBeAg, HBV DNA >10^4IU/ml and elevated ALT. Combined response ( CR ) were defined as the lack of serum HBeAg, low or undetectable HBV DNA levels ( <2000IU/ml ), and ALT normalization after receiving antiviral therapy. Vertical group: Children with HBsAg or HBV DNA positive at least 6 months were treated with entecavir and followed up for at least 48 weeks in our hospital

排除标准:

合并肝硬化失代偿、肝细胞癌、肝功能衰竭、肝移植、慢性免疫抑制状态、其他肝病(如自身免疫性肝炎、药物性肝损伤或威尔逊病)或感染其他嗜肝病毒(如丙型肝炎病毒)的患者

Exclusion criteria:

Patients with decompensated cirrhosis, hepatocellular carcinoma, liver failure, liver transplantation, chronic immunosuppressive status, other liver diseases (such as autoimmune hepatitis, drug-induced liver injury or Wilson's disease) , or infection with other hepatophilic viruses (such as Hepatitis C virus)
