慢性乙型肝炎病毒感染者HBeAg血清学自然转换及其影响因素分析

目的了解慢性乙型肝炎病毒(hepatitis B virus,HBV)感染者乙型肝炎e抗原(hepatitis Be antigen,HBe Ag)血清学自然转换及其影响因素。方法以寿光市2012年3个强化干预镇街道农村居民乙型病毒性肝炎(简称乙肝)专项调查确诊的HBe Ag阳性感染者的血清学检测结果为基线,与2015年随访的血清学检测结果对比分析。用ELISA检测乙肝血清标志物,用实时荧光定量PCR检测HBV DNA载量,采用速率法检测丙氨酸氨基转移酶(alanine aminotransferase,ALT)。结果 HBe Ag阳性者340例,随访3年,HBe Ag转阴142例,年转阴率13.92%;抗-HBe转换92例,年转换率9.02%。HBe Ag转阴/转换率与HBV DNA载量负相关(r=-0.227,P0.001;r=-0.193,P0.001);HBe Ag转阴/转换率与年龄有关,6~20岁组转阴/转换率低,随年龄增长HBe Ag转阴/转换率增高,各年龄组差异均有统计学意义(χ2=22.74,P0.01;χ2=30.34,P0.01);性别不是HBe Ag转换率的主要影响因素(P0.05)。血清学转换后,HBV DNA载量、ALT水平均较转换前有明显的下降,但仍有一定比例的感染者检出高拷贝的HBV DNA载量。结论 HBV感染过程中存在着HBe Ag血清学自然转换,年龄是HBV DNA载量的主要影响因素,HBe Ag与HBV DNA载量的变化并不完全一致。

恩替卡韦治疗对HBeAg阳性乙肝患者血清和肝组织中HBV cccDNA的影响

目的探讨口服恩替卡韦治疗HBe Ag阳性乙肝患者1年对血清和肝组织中HBV cccDNA含量的影响。方法选取90例HBe Ag阳性乙肝患者,所有患者连续48周口服恩替卡韦0.5 mg/d,治疗前后分别静脉取血分离血清。采用化学发光法检测HBV血清标志物、采用荧光实时定量PCR法检测HBV-DNA及HBV cccDNA含量,并对各指标进行统计学分析。选取治疗48周后血清HBV cccDNA阴性且符合肝穿的患者进行肝穿检查,检测肝组织中HBV cccDNA含量。结果 (1)治疗后,血清HBV-DNA、HBV cccDNA及谷丙转氨酶(ALT)水平均显著下降(P0.01)。(2)发生e抗原转换组的HBV DNA和HBV cccDNA水平下降均比未发生转换组更显著(P0.01)。(3)90例患者在治疗1年后有68例患者血清中HBV cccDNA转阴,而在这其中选取8例患者进行肝穿,只有1例患者的肝组织中HBV cccDNA转阴。结论尽管恩替卡韦可明显降低乙肝患者血清和肝组织的HBV cccDNA水平,然而恩替卡韦治疗1年尚不能彻底清除肝细胞中的HBV。     

乙型肝炎病毒感染Babl/c乳鼠动物模型的研究

目的:目前HBV感染动物模型各有局限,无法全面研究HBV。拟建立人HBV血清感染Babl/c乳鼠的动物模型,以便于研究HBV感染与乳鼠免疫力低下的相关性。方法:将20只Babl/c乳鼠随机分为实验组、对照组、PBS组及空白组,通过高压水动力尾静脉注射法将人HBV血清、正常人血清、PBS注入各组乳鼠体内,记录接种后乳鼠体温及体质量。于接种后第7、15、30 d采集血清标本,应用ELISA检测HBs Ag、HBe Ag的表达情况,实时荧光定量PCR检测HBV DNA浓度。结果:接种后各组小鼠体温及体质量均无明显变化。实验组中共4只乳鼠可检测到HBs Ag为阳性且维持时间长达30 d,但HBe Ag均为阴性,HBV DNA浓度均未达500 IU/ml;余下各组检测HBs Ag、HBe Ag均为阴性。结论:通过高压水动力尾静脉注射法接种人HBV血清,可成功使Babl/c乳鼠感染HBV。本实验证实乳鼠免疫力低下,HBV血清进入体内未能有效清除,对HBV存在易感性,为建立HBV感染动物模型提供实验依据,可用于研究HBV对免疫状态的影响。     

HBV感染者外周血PBMC中TLR4 mRNA与病毒载量的相关性研究

目的探讨乙型肝炎病毒感染者外周血PBMC中TLR mRNA与乙肝病毒复制的相关性。方法采用逆转录PCR检测外周血单个核细胞（PBMC）中TLR4 mRNA的含量,实时荧光定量Real Time PCR的方法检测HBV DNA,进行相关性分析。结果不同病毒载量组（〈1×103copies/μg DNA,1×103copies/μg DNA〈且〈1×105copies/μg DNA,〉1×105copies/μg DNA）TLR4 mRNA水平差异具有显著性（P〈0.01）,HBV病毒载量的对数值与TLR4 mRNA的含量存在负相关（r=-0.537,P〈0.01）。TLR4 mRNA的相对表达量与患者的ALT、AST呈正相关（r=0.608、r=0.659,P〈0.01）。结论HBV在患者体内复制活跃、病毒载量增高与外周血单个核细胞TLR4mRNA的表达下调有关。     

乙型肝炎病毒e抗原定量检测的性能验证和临床应用探索

乙型肝炎病毒e抗原(hepatitis B e antigen, HBeAg)的定量检测对乙型肝炎临床诊疗具有一定的重要性,但其定量检测还未成为常规检验项目。本研究对HBeAg定量检测系统进行性能验证,比较HBeAg定量和定性检测的相关性和一致性,分析HBeAg定量结果和乙型肝炎病毒DNA(hepatitis B virus DNA, HBV DNA)的关系,为HBeAg定量检测在临床诊疗的应用提供依据。通过收集710例2019年3月至5月于复旦大学附属华山医院就诊的慢性乙型肝炎患者血清样本,参照美国临床实验室标准化协会(The Clinical & Laboratory Standards Institute, CLSI)相关文件的要求,对雅培ARCHITECTi4000SR全自动免疫分析仪检测的HBeAg定量试剂的精密度、分析灵敏度、线性范围/可报告范围、携带污染率进行验证和评价;采用化学发光微粒子免疫检测技术(chemiluminescence microparticle immuno assay, CMIA)对618例患者进行HBeAg定性和定量检测;采用荧光定量PCR对慢性乙型肝炎患者进行HBV DNA检测,比较HBV DNA和HBeAg定量结果的相关性。本研究证实HBeAg定量试剂检测性能验证结果良好;HBeAg定量和定性检测相关性良好;126例同时有HBeAg定量检测和HBV DNA定量检测的结果显示,两种方法呈正相关且一致性良好。HBeAg定量检测可用于常规实验室检测来辅助HBV感染的临床诊疗。

Levels of hepatitis B virus replicative intermediate in serum samples of chronic hepatitis B patients

Hepatitis B virus (HBV) cccDNA levels is an absolute marker of HBV replication in the liver of HBV infected patients. This study aimed to quantify the HBV cccDNA levels in sera and liver tissue samples of treatment naïve patients with chronic hepatitis B. Eighty one chronic hepatitis B (CHB) treatment naïve patients were enrolled from January 2009 to June 2011. Total HBV DNA and HBV cccDNA levels were quantified using sensitive real time PCR assay. The mean age of recruited patients was 34 ± 11.5 years. Fifty four (66.7 %) patients were HBeAg negative. Liver tissue samples were available from 2 HBeAg positive and 21 HBeAg negative CHB patients. The amount of total intrahepatic HBV DNA ranged from 0.09 to 1508.92 copies/cell. The median intrahepatic HBV cccDNA was 0.31 and 0.20 copies/cell in HBeAg positive and HBeAg negative cases, respectively. Serum HBV cccDNA was detectable in 85.2 % HBeAg positive and 48.1 % HBeAg negative CHB patients. Median serum HBV cccDNA was 46,000 and 26,350 copies/mL in HBeAg positive and HBeAg negative subjects, respectively. There was a significant positive correlation between the levels of intrahepatic total HBV DNA and intrahepatic HBV cccDNA (r = 0.533, p = 0.009). A positive correlation was also seen between serum HBV cccDNA levels and serum HBV DNA levels (r = 0.871, p < 0.001). It was concluded that serum HBV cccDNA could be detectable in higher proportion of HBeAg positive patients compared to HBeAg negative patients. Moreover, the median level of serum HBV cccDNA was significantly higher in HBeAg positive patients in contrast to HBeAg negative subjects.     

Management of individuals with chronic hepatitis B virus infection and persistent normal or mildly elevated aminotransferase levels

No consensus exists with respect to positive hepatitis B virus (HBV) DNA results and persistent normal or mildly elevated alanine aminotransferase (ALT). The aim of this study is to investigate the appropriate management and prognosis of these populations with chronic hepatitis B (CHB). A total of 235 subjects with positive HBV DNA results and persistent normal or mildly elevated ALT were enrolled in this study. Liver biopsy and liver stiffness measurements (LSM) were performed in all participants at baseline. Antiviral therapy was initiated in patients with significant hepatic inflammation (G ≥ 2) and/or fibrosis (S ≥ 2). The patients were divided into entecavir and adefovir groups based on HBV DNA load (>2000 IU/mL vs <2000 IU/mL). The liver biopsies were repeated at 72 weeks for the patients received antiviral therapy. We found that 112 subjects were hepatitis B e antigen (HBeAg) positive, and 123 subjects were negative. The corresponding median ALTs were 46 (39.5-52.5) and 48 (41.5-57.0) U/mL, respectively. G ≥ 2 and/or S ≥ 2 diseases were present in 48.8% (82/168) of the HBeAg-positive and 51.2% (86/168) of HBeAg-negative patients, respectively. In addition, 96 HBeAg-positive and 72 HBeAg-negative patients were divided into entecavir and adefovir groups. Meanwhile, liver biopsies had greater diagnostic accuracy for determining cirrhosis than LSM (0.711 vs 1.0, P < 0.0001). At the end of the study period, undetectable HBV DNA levels and normal ALT levels were observed in CHB-infected patients. Furthermore, the patients showed histologic improvement at 72 weeks compared with baseline measurements (G, 1.72 ± 1.00 vs 0.73 ± 0.88, P = 0.0002; S, 1.484 ± 0.90 vs 0.99 ± 1.13, P < 0.0001). Collectively, liver biopsy enhanced diagnostic accuracy for CHB-infected individuals with persistent normal or mildly elevated aminotransferase levels. Moreover, antiviral therapy can improve or regress the hepatic fibrosis and cirrhosis.     

CXCL9 Associated with Sustained Virological Response in Chronic Hepatitis B Patients Receiving Peginterferon Alfa-2a Therapy: A Pilot Study

Background and Aims

There is lack of a practical biomarker to predict sustained virological response (SVR) in chronic hepatitis B (CHB) patients undergoing peginterferon alfa-2a (PEG-IFN). The aim of this pilot study was to identify immunological features associated with SVR.

Methods

Consecutive 74 CHB patients receiving 24 weeks (for hepatitis B e antigen (HBeAg)-positive) or 48 weeks (for HBeAg-negative) PEG-IFN, were prospectively enrolled. Serum HBV viral loads, hepatitis B surface antigen (HBsAg), CXCL9, IFN-γ-inducible protein 10 (IP-10), interferon-gamma (IFN-γ) and transforming growth factor beta (TGF-β) were measured at baseline and week 12. SVR was defined as HBeAg seroconversion combined with viral load <2000 IU/mL in HBeAg-positive (n=36), and viral load <2000 IU/mL in HBeAg-negative patients (n=38) at 48 weeks after the end of treatment.

Results

Nineteen patients (25.7%), 7 in HBeAg-positive and 12 in HBeAg-negative, achieved SVR. There were significant declines of HBV DNA, HBsAg, IP-10 and IFN-γ levels at week 12. In multivariate analysis, pre-treatment CXCL9 >80 pg/mL, HBV DNA <2.5 x 10⁷ IU/mL and on-treatment HBV viral load, HBsAg decline >10% at week 12 were predictors of SVR. The performance of CXCL9 in predicting SVR was good in patients with HBV DNA <2.5 x 10⁷ IU/mL, particularly in HBeAg-negative CHB cases (positive predictive value, PPV= 64.3%).

Conclusions

Pre-treatment CXCL9 level has the potential to select CHB patients who can respond to PEG-IFN, especially in HBeAg-negative patients with low viral loads.     

Long-Term Hepatitis B Virus (HBV) Response to Lamivudine-Containing Highly Active Antiretroviral Therapy in HIV-HBV Co-Infected Patients in Thailand

BACKGROUND: Approximately 4 million of people are co-infected with HIV and Hepatitis B virus (HBV). In resource-limited settings, the majority of HIV-infected patients initiate first-line highly active antiretroviral therapy containing lamivudine (3TC-containing-HAART) and long-term virological response of HBV to lamivudine-containing HAART in co-infected patients is not well known. METHODOLOGY/PRINCIPAL FINDING: HIV-HBV co-infected patients enrolled in the PHPT cohort (ClinicalTrials.gov NCT00433030) and initiating a 3TC-containing-HAART regimen were included. HBV-DNA, HIV-RNA, CD4+ T-cell counts and alanine transaminase were measured at baseline, 3 months, 12 months and then every 6 months up to 5 years. Kaplan-Meier analysis was used to estimate the cumulative rates of patients who achieved and maintained HBV-DNA suppression. Of 30 co-infected patients, 19 were positive for HBe antigen (HBeAg). At initiation of 3TC-containing-HAART, median HBV DNA and HIV RNA levels were 7.35 log(10) IU/mL and 4.47 log(10) copies/mL, respectively. At 12 months, 67% of patients achieved HBV DNA suppression: 100% of HBeAg-negative patients and 47% of HBeAg-positive. Seventy-three percent of patients had HIV RNA below 50 copies/mL. The cumulative rates of maintained HBV-DNA suppression among the 23 patients who achieved HBV-DNA suppression were 91%, 87%, and 80% at 1, 2, and 4 years respectively. Of 17 patients who maintained HBV-DNA suppression while still on 3TC, 4 (24%) lost HBsAg and 7 of 8 (88%) HBeAg-positive patients lost HBeAg at their last visit (median duration, 59 months). HBV breakthrough was observed only in HBeAg-positive patients and 6 of 7 patients presenting HBV breakthrough had the rtM204I/V mutations associated with 3TC resistance along with rtL180M and/or rtV173L. CONCLUSIONS: All HBeAg-negative patients and 63% of HBeAg-positive HIV-HBV co-infected patients achieved long-term HBV DNA suppression while on 3TC-containing-HAART. This study provides information useful for the management of co-infected patients in resource-limited countries where the vast majority of co-infected patients are currently receiving 3TC.     

Long-term effects of peginterferon alfa-2a therapy in Japanese patients with chronic hepatitis B virus infection

Background

There is no information on the long-term effects of peginterferon (PEG-IFN) alfa-2a therapy for chronic hepatitis B (CHB) in Japan. This double-blind, randomized trial investigated the efficacy of PEG-IFN therapy.

Methods

We analyzed 22 Japanese patients with CHB (hepatitis B e antigen [HBeAg]-positive: 17, HBeAg-negative: 5) treated with PEG-IFN alfa-2a and followed-up posttreatment for 5 years. Responders represented patients who showed persistent normalization of alanine transferase (ALT) levels, HBeAg clearance, and low hepatitis B virus (HBV) DNA levels (HBeAg-positive patient; <5 log copies/mL, HBeAg-negative patient; <4.3 log copies/mL) at end of treatment, and at 1, 2, 3, 4 and 5 years posttreatment. In addition, baseline HBeAg-positive patients who showed sustained normalization of ALT level, HBeAg clearance, and low HBV DNA level for more than 6 months until at 1, 2, 3, 4, and 5 years after completion of PEG-IFN were also classified as “triple responders” and the proportion of triple responders relative to all patients was termed the “triple response rate”.

Results

The response rates among HBeAg-positive patients were 13 %, 25 %, 14 %, 21 % and 21 % at end of treatment, and at 1, 2, 3, 4, and 5 years, respectively. The response rate tended to be higher in patients treated for 48 than 24 weeks. The respective response rates among HBeAg-negative patients were 0 %, 20 %, 20 %, 20 % and 25 %. During the treatment period, hepatitis B surface antigen (HBsAg) clearance at 3.5 years was noted in one patient, who was 37-year-old, male, had genotype C and received PEG-IFN alfa-2a at 90 μg for 48 weeks.

Conclusion

At 5 years after completion of PEG-IFN, the triple response rate in HBeAg-positive patients and combined response rate in HBeAg-negative patients were 21 % (3/14) and 25 % (1/4), respectively. The triple response was seen in three patients who had all been treated with PEG-IFN for 48 weeks.

     

Pegylated-Interferon Alpha Therapy for Treatment-Experienced Chronic Hepatitis B Patients

Background

Studies are limited on pegylated interferon (Peg-IFN) therapy for chronic hepatitis B (CHB) patients who failed or relapsed on previous antiviral therapy.

Objectives

We aimed to investigate the effect of Peg-IFN therapy in treatment-experienced CHB patients.

Study Design

A total of 57 treatment-experienced CHB patients at two medical centers were enrolled. All of the patients were treated with Peg-IFN α-2a at 180 μg weekly for 24 or 48 weeks. The hepatitis B serological markers and viral loads were tested every 3 months until 1 year after stopping Peg-IFN therapy. The endpoints were HBV DNA <2000IU/mL, hepatitis B e antigen (HBeAg) seroconversion, and a hepatitis B surface antigen (HBsAg) loss at 12 months post-treatment.

Results

In HBeAg-positive patients, 25.0%, 29.2%, and 12.5% of the patients achieved HBeAg seroconversion, HBV DNA <2000 IU/mL and a combined response, respectively, at 12 months post-treatment. Prior IFN therapy, a high baseline ALT level, a low creatinine level, undetectable HBV DNA at 12 weeks and a decline in HBV DNA >2 log₁₀ IU/mL at 12 weeks of therapy were factors associated with treatment response. In HBeAg-negative patients, 9.1%, 15.2%, and 6.1% of the patients achieved undetectable HBV DNA, HBV DNA <2000 IU/mL, and an HBsAg loss, respectively, at 12 months post-treatment. No factor was significantly associated with the treatment response in the HBeAg-negative patients. The median HBsAg level declined from 3.4 to 2.6 log₁₀ IU/mL in all the patients, and the 5-year cumulative rate of the HBsAg loss was 9.8% in the HBeAg-negative patients. Overall, none of the patients prematurely discontinued the Peg-IFN therapy.

Conclusions

Peg-IFN re-treatment is effective for a proportion of HBeAg-positive treatment-experienced patients; it has limited efficacy for HBeAg-negative treatment-experienced patients. Peg-IFN might facilitate HBsAg loss in HBeAg-negative treatment-experienced patients.     

Effects of Entecavir on Hepatitis B Virus Covalently Closed Circular DNA in Hepatitis B e Antigen-Positive Patients with Hepatitis B

The aim of this study was to assess the effect of 48-week entecavir therapy on serum and intrahepatic hepatitis B virus, covalently closed circular DNA (HBV cccDNA) levels in hepatitis B e antigen (HBeAg)-positive patients. A total of 120 patients with HBeAg-positive chronic hepatitis were treated with entecavir for 48 weeks. Serum HBV markers, total HBV DNA, and HBV cccDNA levels were measured at baseline and week 48. Biopsies from 20 patients were available for both intrahepatic total HBV DNA and cccDNA testing at these timepoints. HBV cccDNA levels were decreased from a median level of 5.1×10⁶ copies/mL at baseline to a median level of 2.4×10³ copies/mL at week 48. Reduction magnitudes of HBV cccDNA in patients with normalized alanine aminotransferase levels and those undergoing HBeAg seroconversion were significantly greater than those in alanine aminotransferase-abnormal and HBeAg positive patients. Intrahepatic HBV cccDNA was decreased significantly after 48 weeks of treatment, but could not be eradicated. In conclusion, treatment of HBeAg-positive hepatitis B patients with entecavir for 48 weeks decreased serum and intrahepatic HBV cccDNA significantly, and the magnitude of HBV cccDNA reduction was related to total HBV DNA decrease, alanine aminotransferase normalization, and HBeAg seroconversion.     

干扰素-α治疗HBeAg阴性慢性乙型肝炎患者的早期疗效及影响因素分析

目的探讨HBeAg阴性慢性乙型肝炎(CHB)患者干扰素-α(IFN-α)早期疗效的影响因素。方法收集40例HBeAg阴性CHB患者,检测IFN-α治疗前及治疗12周时的ALT、HBV DNA、HBsAg、HBsAb、HBeAg、HBeAb、HBcAb;分析年龄、性别、ALT基线水平、HBV DNA基线水平对IFN-α疗效的影响。结果性别组间、不同年龄段组间、不同ALT基线水平组间、不同HBV DNA基线水平组间比较IFN疗效差异无统计学意义(P>0.05)。结论性别、年龄、ALT基线水平、HBV DNA基线水平、年龄不可以作为预测IFN-α治疗HBeAg阴性慢性乙型肝炎患者的早期疗效指标。
