Abstract
BACKGROUND & AIMS:

Hepatitis B virus (HBV) contains three viral surface proteins, large, middle and small hepatitis B surface protein (LHBs, MHBs, SHBs). Proportions of LHBs and MHBs are lower in patients with inactive versus active chronic infection. Interferon alfa may convert HBeAg-positive chronic hepatitis B (CHB) to an inactive carrier state, but prediction of sustained response is unsatisfactory. The aim of this study was to test the hypothesis that quantification of MHBs and LHBs may allow for a better prognosis of therapeutic response than total hepatitis B surface antigen (HBsAg) concentration.
METHODS:

HBs proteins were measured before and during peginterferon alfa-2a therapy in serum from 127 Asian patients with HBeAg-positive CHB. Sustained response was defined as hepatitis B e antigen (HBeAg) seroconversion 24 weeks post-treatment.
RESULTS:

Mean total HBs levels were significantly lower in responders versus nonresponders at all time points (P<.05) and decreased steadily during the initial 24 weeks' treatment (by 1.16 versus 0.86 ng/mL in responders/nonresponders, respectively) with unchanged relative proportions. Genotype B had a twofold higher proportion of LHBs than genotype C (13% versus 6%). HBV DNA, HBeAg, HBsAg, and HBs protein levels predicted response equally well but not optimally (area under the ROC curve values >0.70).
CONCLUSIONS:

HBs proteins levels differ by HBV genotype. However, quantification of HBs proteins has no advantage over the already established HBsAg assays to predict response to peginterferon alfa-2a therapy in HBeAg-positive patients.

抽象
背景与目的:

乙型肝炎病毒(HBV)包含三种病毒表面蛋白,即大,中,小型乙型肝炎表面蛋白(LHBs,MHBs,SHBs)。非活动性慢性感染与活动性慢性感染患者中,LHBs和MHBs的比例较低。干扰素α可能会将HBeAg阳性的慢性乙型肝炎(CHB)转变为无活性的携带者状态,但对持续反应的预测并不令人满意。这项研究的目的是检验以下假设,即定量MHBs和LHBs可能比总乙型肝炎表面抗原(HBsAg)浓度更好的预后。
方法:

在peeginterferon alfa-2a治疗之前和期间,对来自127名亚洲HBeAg阳性CHB患者的血清中的HBs蛋白进行了测量。持续反应定义为治疗后24周的乙肝e抗原(HBeAg)血清转化。
结果:

在所有时间点,反应者的平均总HBs水平均显着低于未反应者(P <.05),并且在最初的24周治疗期间稳步下降(相对者未反应者分别降低了1.16和0.86 ng / mL)。 。基因型B的LHBs比例是基因型C的两倍(13%比6%)。 HBV DNA,HBeAg,HBsAg和HBs蛋白水平预测的反应同样好,但不是最佳的(ROC曲线值> 0.70的区域)。
结论:

HBs蛋白水平因HBV基因型而异。但是,与已经建立的HBsAg分析相比,对HBs蛋白进行定量分析无法预测HBeAg阳性患者对聚乙二醇干扰素alfa-2a治疗的反应。
