乙型肝炎病毒载量与抗原抗体模式的关系

目的探讨乙型肝炎病毒载量与抗原抗体模式的关系,为乙型肝炎的诊治、预防提供科学依据. 方法用实时荧光定量聚合酶链反应和ELISA检测HBV DNA和抗原抗体,统计分析不同抗原抗体模式的HBV DNA量. 结果在HBsAg和HBeAg阳性模式中,HBV DNA拷贝数＞103/ml者占87.3%,其中＞107/ml者占66.7%;在HBsAg阳性,抗-HBe阳性模式中,HBV DNA拷贝数＜103/ml者占74.5%,＞107/ml者占8.3%;在HBsAg阳性,抗-HBc阳性模式中,HBV DNA拷贝数＞103/ml者占48.0%,＞107/ml者占29.1%.HBeAg阳性模式HBV 载量显著高于HBeAg阴性模式(P＜0.01).抗-HBe阴性模式HBV载量显著高于抗-HBe阳性模式(P＜0.01).在HBsAg阴性模式中,HBV DNA拷贝数＞103/ml占7.9%,1例拷贝数高达1.59×109/ml. 结论 HBeAg阳性模式HBV 载量显著高于HBeAg阴性模式,抗-HBe 阴性模式病毒载量显著高于抗-HBe阳性模式,HBeAg阳性模式中的少数人HBV载量很低,HBeAg阴性模式中少数人HBV载量很高,HBsAg阴性模式中少数人存在病毒复制,因此,对于一具体患者来说,根据抗原抗体模式,难以准确地判断病毒复制程度及其传染性的强弱.     

前S1抗原在乙肝病毒感染与复制中的作用

目的 传统乙肝血清标志物是目前我国用于乙肝检测与筛查较普及的指标,但传统乙肝HBV-M检测在病毒复制等一些方面尚有不足.本研究分析前S1（Pre-S1）抗原在判断乙肝病毒的感染与复制中的作用.方法 HBV-M和Pre-S1抗原检测采用ELISA法;HBV DNA检测采用实时荧光定量PCR技术.结果 （1）Pre-S1抗原在乙肝病毒早期感染中的作用：787例ALT正常血清中,Pre-S1抗原阳性34例,HBV-M检测HBsAg（＋）2例,HBsAg（＋）、HBeAg（＋）1例,HBsAg（＋）、HBeAg（＋）、HBcAb（＋）7例,HBsAg（＋）、HBeAb（＋）、HBcAb（＋）18例,HBsAg（＋）、HBcAb（＋）4例,HBV DNA阳性35例,三者检出结果高度符合,无显著差异（P＞0.05）.（2）Pre-S1抗原在乙肝病毒复制中的作用：816例慢性乙肝患者中,HBeAg（＋）/HBeAb（-）396例,Pre-S1抗原阳性357例,HBV DNA阳性371例,阳性检出率分别为90.1%和93.6%.HBeAg（-）/HBeAb（＋）285例,Pre-S1抗原阳性223例,HBV DNA阳性247例,阳性检出率分别为78.2%和86.7%.HBeAg（-）/HBeAb（-）135例,Pre-S1抗原阳性85例,HBV DNA阳性105例,阳性检出率分别为62.9%和77.7%,若以HBV DNA≥103copy/ml为判断乙肝病毒存在复制的标准,则Pre-S1抗原的检出率为79%（414/525）,HBeAg（＋）的检出率为32.7%（172/525）;Pre-S1抗原、HBeAg（＋）与HBV DNA的总符合率分别为78.8%（615/723）、45.5%（327/723）,HBV DNA与Pre-S1抗原检出率差异无显著性（P＞0.05）,HBeAg（＋）与HBV DNA检出率差异有显著性（P＜0.05）.结论 Pre-S1抗原是乙肝病毒早期诊断与病毒复制的重要标志.

E抗原和E抗体阳性的慢性乙型肝炎组织病理学研究

目的探讨HBeAg阳性和抗-HBe阳性的慢性乙型肝炎患者的肝组织病理改变的差异性.方法分别对151例HBeAg阳性和62例抗-HBe阳性的慢性乙型肝炎患者进行肝活检,观察肝组织病理分级和分期情况,同时检测血清HBV DNA.结果 (1)肝组织病理分级、分期与血清HBeAg/抗-HBe的出现情况密切相关,抗-HBe阳性者中肝组织病理为G3～G4、S3～S4者明显多于G1～G2、S1～S2者;而在HBeAg阳性者中则相反;两组比较差异有显著性(P＜0.005);(2)在HBeAg阳性患者中HBV DNA检出率为83.4%(126/151);而在抗-HBe阳性患者中HBV DNA检出率为29%(18/62).结论 (1)抗-HBe阳性的慢性乙型肝炎患者中肝组织炎症、坏死及肝纤维化的程度较HBeAg阳性者严重;(2)HBeAg与HBV DNA存在良好的相关性,但在部分抗-HBe阳性的患者中仍可检出HBV DNA.     

定量检测血清HBV标志物不同阳性组合模式与HBV DNA定量之间的关系

目的探讨定量检测乙型肝炎病毒血清标志物(HBVM)与HBV DNA定量之间的关系。方法采用实时荧光定量PCR仪检测HBV DNA，采用时间分辨荧光免疫分析仪检测HBVM。结果371例乙型肝炎患者表现12种阳性模式，除常见模式外，发现3种HBVM特殊模式，即抗-HBe与HBeAg共存，即抗-HBs与HBeAg或与HBsAg共存模式。含有HBeAg的各种模式病毒含量高，病毒复制活跃，HBV DNA阳性率多数较高。结论时间分辨荧光免疫分析法是一种敏感、特异方法，HBVM各项指标中，抗原意义远大于抗体意义，只要有HBeAg存在的模式，就代表病毒复制活跃及传染性强。抗-HBe与HBeAg共存或抗-HBs与-HBeAg或与HBsAg共存时，抗-HBs不能清除HBV，抗-HBs及抗-HBe也不代表病毒复制减少。     

定量PCR检测乙型肝炎患者血清HBV DNA及其临床意义

Disappearance of serum hepatitis B virus DNA by polymerase chain reaction after adenine arabinoside 5‘-monophosphate therapy in chronic hepatitis B

ABSTRACT— The aim of antiviral therapy in chronic hepatitis B is the cessation of viral replication, which may be demonstrated by the loss of hepatitis B “e” antigen (HBeAg) and serum hepatitis B virus DNA (HBV-DNA) detected by dot-blot hybridization. With the development of the sensitive polymerase chain reaction (PCR) technique for detecting HBV-DNA, it has become apparent that many HBeAg negative patients may still have small amounts of circulating viral DNA. We assessed 19 of 25 patients with chronic hepatitis B who seroconverted from HBeAg to anti-HBe after adenine arabinoside 5′-monophosphate therapy (5 mg ·kg^-1 · day^-1 for 7 weeks) to determine whether serum HBV-DNA became undetectable. Sixteen of the 19 HBeAg negative patients remained hepatitis B surface antigen (HBsAg) positive, and the other three lost HBsAg during follow-up. All of them were HBV-DNA negative by dot-blot hybridization. Using the PCR technique, HBV-DNA became negative in 13 (81.2%) of the 16 patients who seroconverted to anti-HBe without losing HBsAg, and in all the patients who lost HBsAg. These data suggest that the majority of patients who respond to adenine arabinoside 5′-monophosphate show a complete inhibition of hepatitis B virus replication, as demonstrated by the absence of viral DNA by PCR. This inhibition was present in all patients who, at the same time, lost HBsAg.     

Expression of pre-S gene-encoded proteins in liver and serum during chronic hepatitis B virus infection in comparison to other markers of active virus replication

Pre-S gene-encoded proteins of the hepatitis B virus (HBV) were studied in the liver by immunofluorescence and in serum by radioimmunoassay in 30 patients with chronic HBV infection. The results were compared with molecular hybridization analysis of HBV-DNA in liver and serum, with serum hepatitis B e antigen/antibody (HBeAg/anti-HBe) status and with underlying liver histology. Pre-S peptides were detected in the serum of 11 patients, 10 of whom were positive for serum HBV-DNA and/or liver hepatitis B core antigen. Only 4 of these patients were HBeAg positive. The prevalence of serum pre-S among HBV replicating carriers was 59% (10/17) compared to only 8% (1/13) among those with non-replicating virus (P less than 0.01). All patients with circulating pre-S peptides had active liver disease. Anti-pre-S was detected in the serum of only 4 patients, 3 with integrated HBV-DNA. In contrast to serum findings, pre-S peptides were detected in the liver of all patients with histochemically demonstrable hepatitis B surface antigen (HBsAg), regardless of HBV replicative status. HBsAg carriers with integrated HBV-DNA had abundant cytoplasmic pre-S1 and pre-S2 localized in numerous ground-glass hepatocytes. It is concluded that pre-S peptides are usually displayed in the liver simultaneously with histochemically detectable HBsAg; they are secreted in the serum in association with high HBV replication and release of HBV particles, but in the absence of episomal HBV replication, pre-S peptides seem to be largely retained within hepatocytic membranes.     

HBeAg negative serological status and low viral replication levels characterize chronic hepatitis B virus-infected women at reproductive age in Greece： A one-year prospective single center study

AIM: To evaluate the seroprevalence of hepatitis B surface antigen (HBsAg) in 13 581 women at reproductive age and the hepatitis B e antigen (HBeAg)/anti-HBe status as well as serum hepatitis B virus (HBV)-DNA levels in a subgroup of HBsAg(+) pregnant women at labor in Greece. METHODS: Serological markers were detected using enzyme immunoassays. Serum HBV-DNA was determined by a sensitive quantitative PCR assay. Statistical analysis of data was based on parametric methodology. RESULTS: Overall, 1.156% of women were HBsAg(+) and the majority of them (71.3%) were Albanian. The prevalence of HBsAg was 5.1% in Albanian women, 4.2% in Asian women and 1.14% in women from Eastern European countries. The prevalence of HBsAg in African (0.36%) and Greek women (0.29%) was very low. Only 4.45% of HBsAg (+) women were also HBeAg(+) whereas the vast majority of them were HBeAg(-)/anti-HBe(+). Undetectable levels of viremia (<200 copies/mL) were observed in 32.26% of pregnant women at labor and 29.03% exhibited extremely low levels of viral replication (<400 copies/mL). Only two pregnant women exhibited extremely high serum HBV-DNA levels (>10 000 000 copies/mL), whereas 32.26% exhibited HBV-DNA levels between 1 500 and 40 000 copies/mL. CONCLUSION: The overall prevalence of HBsAg is relatively low among women at reproductive age in Greece but is higher enough among specific populations. The HBeAg(-)/anti-HBe(+) serological status and the extremely low or even undetectable viral replicative status in the majority of HBsAg(+) women of our study population, suggest that only a small proportion of HBsAg(+) women in Greece exhibit a high risk for vertical transmission of the infection.     

Detection of proteins encoded by the pre-S region of hepatitis B virus in the sera of HBsAg carriers: relation to viral replication

In order to determine the relationship between the presence of pre-S1 and pre-S2 proteins and the level of hepatitis B virus (HBV) replication, a study of 94 HBsAg chronic carriers, 15 anti-HBe positive patients who suffered a viral reactivation and 12 HBeAg, HBV-DNA positive cases under antiviral therapy, has been carried out. Pre-S1 and pre-S2 antigens were detected by RIA using polystyrene beads coated with anti-preS1 or anti-preS2 (Dr W. Gerlich, G?ttingen) and 125I-anti-HBs as tracer. The presence of pre-S1 and pre-S2 antigens was detected in 74 (79%) and 85 (90%), respectively, out of the 94 HBsAg chronic carriers included. The level of these antigens was significantly higher in HBeAg, HBV-DNA positive patients than in the other patients (p less than 0.05). Among anti-HBe positive patients suffering a reactivation, a significant increase of pre-S1 and pre-S2 levels was observed, concurring with ALT exacerbation and HBV-DNA positivity. After reactivation, the level of pre-S antigens returned to the basal values. A significant decrease in pre-S antigen levels (p less than 0.05) among patients who respond to recombinant interferon therapy was observed, while no changes were detected among non-responder cases. The detection of pre-S1 and pre-S2 antigens in serum is more frequent in those patients with high viral replication. Furthermore, among anti-HBe carriers with a viral reactivation, synthesis of pre-S antigens takes place again.

Effects of prednisolone/azathioprine in chronic hepatitis B viral infection.

Changes in markers of hepatitis B viral replication and standard liver function tests were studied in 30 patients with HBsAg positive chronic liver disease starting or stopping prednisolone/azathioprine therapy, and compared with those occurring in 15 patients who did not receive therapy. On stopping prednisolone/azathioprine, 10 out of 11 HBeAg positive patients and one out of three patients negative for HBeAg and anti-HBe, lost HBV-DNA polymerase activity (p less than 0.01), five lost HBeAg, three developed anti-HBe and HBsAg concentration decreased (p less than 0.01). Only one out of seven untreated HBeAg positive patients lost HBeAg and there were no significant changes in DNA polymerase activity. In the anti-HBe positive patients, 14 starting therapy and eight untreated, there were no significant changes in the markers of viral replication - although two patients developed DNA polymerase activity on high maintenance doses of prednisolone - but a significant decrease (p less than 0.05) in aspartate transaminase in the treated group. It is concluded that the cessation of prednisolone/azathioprine therapy in HBeAg positive patients will result in a reduction in viral replication. In anti-HBe positive patients such therapy may be beneficial.     

原发性肝癌患者血清HBV标志物和HBV DNA测定的临床意义

目的观察原发性肝癌患者血清HBV标志物模式及HBV DNA水平。方法采用化学发光法检测151例PHC、132例慢性乙型肝炎和140例乙型肝炎肝硬化患者血清乙型肝炎病毒标记物;采用聚合酶链反应检测血清HBV DNA水平。结果在151例原发性肝癌患者中,HBV感染率达97.4%（147/151）,HBV DNA阳性率为74.8%（113/151）,平均水平为5.6±1.1 lgcopies/ml;HBsAg（＋）、HBeAb（＋）、HBcAb（＋）90例（59.6%）,其血清HBVDNA检出率为76.7%,平均水平为5.1±0.9lgcopies/ml;HBsAg（＋）、HBeAg（＋）、HBcAb（＋）38例（25.2%）,血清HBVDNA检出率100.0%,平均水平为6.4±0.9 lgcopies/ml。结论 PHC患者HBV感染率高,HBV与PHC发生有十分密切的关系。随着慢性乙型肝炎和乙型肝炎肝硬化病情的进展,血清HBeAg自发性发生血清学转换和HBV DNA载量下降,要警防原发性肝癌的发生。
