Patients with chronic hepatitis B virus infection and positive for the hepatitis B e antigen had a greater chance of hepatitis B surface antigen seroclearance after experiencing spontaneous seroclearance of the hepatitis B e antigen, according to data from a recent study.
Clinical data from 775 patients enrolled at the Hepatitis and Liver Clinic of Queen Mary Hospital, Hong Kong, were collected between September 2005 and September 2007 to determine any factors associated with HBsAg seroclearance. Every patient underwent HBeAg seroclearance and were followed until January 2013. Patients were divided into three groups: group 1 consisted of patients that underwent HBeAg seroclearance and did not undergo or require treatment (n=428); group 2 included patients who received treatment-induced HBeAg seroclearance (n=197); and group 3 included patients who experienced spontaneous HBeAg seroclearance but needed antiviral therapy after seroclearance (n=150).
Forty-five patients underwent HBsAg seroclearance with a median time of 139 months from HBeAg seroclearance to HBsAg seroclearance. All patients were still HBsAg-negative at the end of follow-up. The rate of reaching HBsAg seroclearance after HBeAg seroclearance increased with time (0.3% at 1 year vs. 23.6% at 25 years).
HBsAg seroclearance was highest among patients in group 1 compared with patients in group 2 or 3. The HBsAg seroclearance rate at 25 years was 38% in group 1, 14.9% in group 2 and 0% in group 3 patients (P<.001). Multivariate analysis showed stable HBeAg antibodies and HBsAg levels were predictors of HBsAg seroclearance (P=.008).
“Spontaneous HBeAg seroclearance without the need for antiviral therapy afterward was associated with the highest rate of subsequent HBsAg seroclearance,” the researchers wrote. “The levels of HBsAg and not HBV DNA after HBeAg seroclearance were predictive of HBsAg seroclearance. Lower HBsAg levels were associated with higher change of future HBsAg seroclearance.”

慢性乙肝病毒感染,并积极为B型肝炎e抗原有乙肝表面抗原转阴的机会较大遇到乙肝e抗原转阴自发性后,根据从最近的一项研究数据。
从775例患者在玛丽医院,香港的肝炎和肝诊所临床资料收集2005年9月和2007年9月间,以确定与乙肝表面抗原血清清除相关的任何因素。每个病人接受的HBeAg血清廓清和随访,直到2013年1月将患者分为三组:第一组包括该行的HBeAg血清廓清并没有接受或要求治疗组(n=428)的患者;第2组包括谁接受治疗引起的HBeAg血清廓清(N=197)的患者;和第3组包括谁经历自发性HBeAg血清廓清,但需要抗病毒治疗后的血清清除(N=150)的患者。
45例患者接受了乙肝表面抗原转阴了,从e抗原血清廓清对HBsAg血清清除139个月中位时间。所有患者均仍HBsAg阴性在随访结束。 HBeAg的血清清除后达到乙肝表面抗原转阴率(25年时的0.3%,1年与23.6%)随时间增加。
乙肝表面抗原转阴率最高的患者在第1组与组患者相比,2或3。乙肝表面抗原转阴率在25岁为1组的38%,14.9%,第2组和组0%,3组(P<.001) 。多因素分析显示稳定的抗体,e抗原和乙肝表面抗原水平的HBsAg血清清除(P =.008)的预测。
“不需要抗病毒治疗自发性HBeAg血清廓清之后是与后续的HBsAg血清清除率最高的关联,”研究人员写道。 “乙肝表面抗原的水平,而不是HBeAg的血清清除后的HBV DNA是乙肝表面抗原预测转阴的。较低的HBsAg水平与未来的HBsAg血清清除高的变化。“

哪些患者的HBsAg血清学清除率高?
发表时间:2014-10-08 访问量:47标签: 快讯 乙肝 香港玛丽医院Fung等近日完成的一项研究表明,HBeAg阳性慢性乙型肝炎(CHB)患者发生自发性HBeAg血清学清除后不需要抗病毒治疗者,随后的HBsAg血清学清除率最高,HBsAg水平较低也和发生HBsAg血清学清除的机会较大相关。
该研究总共纳入775例HBeAg阳性、发生HBeAg血清学清除的CHB患者,对后来发生HBsAg血清学清除的相关因素进行分析。
在HBeAg血清学清除后第1、5、10、15、20和25年时,HBsAg血清学清除率分别为0.3%、1.3%、3.0%、8.9%、15.7%和23.6%。自发性HBeAg血清学清除后不需要抗病毒治疗患者的HBsAg血清学清除率显著高于接受抗病毒治疗后获得HBeAg血清学清除者,以及自发性HBeAg血清学清除后需要抗病毒治疗的患者。在发生HBeAg血清学清除后第25年时,上述三组的HBsAg血清学清除率分别为38.0%、14.9%和0%(P<0.001)。
获得HBsAg血清学清除患者的中位数HBsAg水平显著低于未获得HBsAg清除者([2.81 vs. 3.52]?log?IU/mL,P=0.009),HBeAg血清学清除后第1年时的HBsAg水平用于预测后来发生HBsAg血清学清除的最佳界值为751?IU/mL,受试者工作特征曲线下面积为0.742。
