Low Serum Hepatitis B Surface Antigen Level Predicts Compensated Cirrhosis Caused by Chronic Hepatitis B in HBeAg Positive Patients in East China

Backgrounds:

Serum hepatitis B surface antigen (HBsAg) levels are associated with fibrosis in patients with chronic hepatitis B (CHB) infection.

Objectives:

The aim of our study was to evaluate serum HBsAg level as a biomarker for compensated cirrhosis in hepatitis B e antigen (HBeAg) positive CHB patients.

Patients and Methods:

Two-hundred and one HBeAg-positive Chinese CHB patients with or without cirrhosis were enrolled in this retrospective study. Cirrhosis was diagnosed based on liver biopsy. Furthermore, patients with decompensated cirrhosis were excluded. A statistical analysis was performed regarding the association between serum HBsAg level and compensated cirrhosis.

Results:

Patients with compensated cirrhosis had a significantly lower mean serum HBsAg level compared to those without cirrhosis (3.27 Log₁₀ IU/mL VS 4.17 Log₁₀ IU/mL, P < 0.001). Furthermore, examining the correlation with compensated cirrhosis revealed that lower level of serum HBsAg was a significant factor in multivariate analysis. The area under the receiver operating characteristics curve of serum HBsAg was 0.856 for compensated cirrhosis. A positive predictive value of 66.2% and negative predictive value of 90.7% were obtained with a cut-off value of < 3.60 Log₁₀ IU/mL (4000 IU/mL) of serum HBsAg. Moreover, the rate of compensated cirrhosis increased to 75.0% after combining with APRI > 2.

Conclusions:

In HBeAg positive CHB patients, low serum HBsAg level is a useful predictor of compensated cirrhosis.     

Baseline Prognostic Factors and Statistic Model to Predict Early Virological Response in Telbivudine-Treated Patients With Chronic Hepatitis B

Background:

Hepatitis B virus (HBV) infection is still a worldwide disease, which may cause liver cirrhosis or even hepatocellular carcinoma. Telbivudine is a potent nucleoside analogue used in the treatment of chronic hepatitis B (CHB); however, drug resistance has remained a challenge. As early virological response can predict long-term efficacy of nucleotide analogue treatment, numerous studies have been conducted in this area.

Objectives:

The aim of this study was to establish baseline prognostic factors and a statistical model to predict early virological response in telbivudine-treated CHB patients.

Patients and Methods:

One hundred and eight CHB patients without any experience of nucleotide analogue therapy were assigned to receive telbivudine (600 mg, once daily) for at least 24 weeks, and then were followed up every two weeks. Cox proportional hazard regression model analyses were employed to evaluate baseline variables, and further developing a statistical model to predict early virological response.

Results:

Negative family history of HBV infection (P = 0.000235), baseline higher serum TBIL (P = 0.038714) and AST (P = 0.020684) concentrations, and lower level of HBV-DNA (P = 0.0034784) were identified to be associated with higher possibility of early virological response. A model was established based on these variables to calculate the risk scores (R) for CHB patients. R > -0.38 suggested early virological response to telbivudine. The model was validated among an independent set of 20 patients.

Conclusions:

Family history as well as baseline bilirubin, AST and HBV DNA levels can predict early virological response. The model provides a better tool for response prediction based on the four prognostic factors.     

慢性乙型肝炎患者血清HBV DNA水平与HBsAg和HBeAg水平的相关性分析

目的探讨慢性乙型肝炎患者血清HBV DNA水平与HBsAg和HBeAg滴度的关系。方法在951例慢性乙型肝炎患者,采用FQ-PCR法和Abbott化学发光微粒子免疫分析技术分别测定血清HBV DNA水平及HBsAg和HBeAg滴度,分析HBV DNA水平与HBsAg和HBeAg滴度的相关性。结果在951例患者中,HBVDNA阳性率为53.83%(512/951);患者血清HBV DNA水平与HBsAg和HBeAg滴度呈正相关(rs=0.45和re=0.49,P<0.05);在HBV DNA水平≥7lg拷贝/毫升患者,血清HBsAg和HBeAg滴度高于HBV DNA为3～7lg拷贝/毫升患者,HBV DNA为3～7lg拷贝/毫升患者血清HBsAg和HBeAg滴度大于HBV DNA<3lg拷贝/毫升患者,差异均有统计学意义(P<0.05);将HBsAg分为<1000 IU/ml、1000～10000 IU/ml和≥10000 IU/ml3组,结果不同HBsAg滴度患者血清HBV DNA水平差异有统计学意义(P<0.05)。结论在血清HBV DNA≥7lg拷贝/毫升和HBsAg滴度≥10000 IU/mL患者,HBV DNA水平与HBsAg滴度呈正相关,在HBV DNA>3 lg拷贝/毫升患者,血清HBV DNA水平与HBeAg滴度呈正相关。     

慢性乙型肝炎拉米夫定治疗后的HBeAg早期血清转换

目的:分析拉米夫定与中成药五灵丸治疗慢性乙型肝炎的临床疗效。方法:对25例成人慢性乙型肝炎患者进行为期1年的拉米夫定的开放性临床治疗,头3个月加用五灵丸。治疗期间定期进行血清ALT、HBeAg、抗-HBe及HBV DNA检测,停药后随访半年。结果:治疗期间共有12例患者(48％)发生HBeAg转阴,并出现抗-HBe;在HBeAg血清转换后的2～4w,8例患者抗-HBe随后消失;在治疗的头3个月随着HBV DNA水平下降及消失(<420copies/ml),所有患者ALT水平逐渐降至正常。结论:治疗头3个月是应用拉米夫定治疗患者HBeAg发生血清转移的关键。这种早期转换的可能解释之一是慢性乙肝患者存在对拉米夫定特别敏感的亚型或种群。     

Hepatitis B virus DNA polymerase activity and hepatitis B e antigen (HBeAg)/anti-HBe status among type B chronic liver diseases

To investigate the relationship between hepatitis B virus (HBV) replication and chronic liver disease, age-specific prevalences of HBeAg, anti-HBe, and HBV DNA polymerase (DNAP) activity were studied in 295 asymptomatic HBV carriers and 183 patients with B-type chronic liver diseases. DNAP activity decreased with age, and there was no difference in the overall prevalence of DNAP activity between the asymptomatic carriers (27.8%) and the chronic liver disease patients (27.3%). The prevalence of DNAP activity in the 40-and-over age group was significantly higher for the chronic liver disease patients (17.5%) than for the asymptomatic carriers (1.7%). The prevalence of HBeAg in the 40- and-over age group was also significantly higher for the chronic liver disease patients (33.8%) than for the asymptomatic carriers (2.6%). These data suggest that viral replication decreased with age and that viral replication occurring in older persons closely related to chronic liver disease.

Abstract：

Objective To investigate the efficacy of Telbivudine and Entecavir for therapy of HBeAg positive chronic hepatitis B for 52 weeks. Methods In this random and control study, the efficacy of Telbivudine and Entecavir treatments were compared in 180 patients with HBeAg positive chronic hepatitis B.The patients were randomly assigned to a daily 600 mg Telbivudine treatment group or daily 0.5 mg Entecavir group for 52 weeks. Results At week 52, HBV DNA undetectable rate was better in the Entecavir-treated group than in the Telbivudine-treated group, but didnt reach statistical signficance. The viral breakthrough rates were significantly lower in the Entecavir-treated group than in the Telbivudine-treated group ( x2 = 4.09, P ＜ 0.05). The clearance and seroconversion of HBeAg and the mean reductions of HBeAg from baseline at week 52 were significantly greater in the telbivudine-treated group than in the entecavirtreated group ( x 2 clearance = 4.63, x2 seroconversion = 4.80, tmean reductions= 2.02; P ＜ 0.05). The HBeAg seroconversion rates were not associated with both baseline ALT and baseline HBV DNA in both groups (P ＞ 0.05). In Telbivudine-treated group, the HBeAg decline＞2 log at week 24, HBeAg decline＞1 log at week 12 and the HBeAg baseline were independent factors correlated to HBeAg seroconversion rates at week 52 by Binary Logistic analysis, and also in entecavir-treated group the HBeAg decline＞2 log at week 24, HBeAg decline ＞2 log at week 36 and the HBeAg decline＞2 log at week 12 were independent factors correlated to HBeAg seroconversion rates at week 52. Conclusion Significant difference of HBeAg seroconversion rates at week 52 existed between Telbivudine-treated group and Entecavir-treated group. Entecavir is significantly superior to Telbivudine with less resistance to nucleosides. HBeAg decline＞2 log at week 24 is the best predicting factor for HBeAg seroconversion at week 52.

Prognostic Values of Fluctuations in Serum Levels of Alanine Transaminase in Inactive Carrier State of HBV Infection

Background:

Current guidelines introduce periodic monitoring of serum alanine transaminase (ALT) as the first-line modality in follow-up patients, with a hepatitis B virus (HBV) inactive carrier state.

Objectives:

This study aimed to determine the incidence rate and patterns of ALT fluctuations and prognostic values for the development of chronic HBV e antigen (HBeAg)-negative hepatitis B (CHB), HBV surface antigen (HBsAg) seroclearance, and liver-related complications.

Patients and Methods:

Treatment-naïve patients with a chronic HBV infection, HBeAg(-)/HBeAb(+), normal ALT levels, and HBV DNA < 2000 IU/mL, were followed-up every 6-12 months by assessing serum ALT levels. Serum HBV DNA was measured in cases of elevated ALT levels.

Results:

A total of 399 patients were followed-up for 8.9 years; ALT > upper limit of normal (ULN, i.e. 40 IU/L) was detected in 103 (25.8%) patients, with an annual incidence rate of 2.9%. ALT elevation was associated with; male gender, age, and higher serum ALT levels at study entry. Among the cases of ALT elevations, 16 (15.5%) patients had ALT levels > 2 × ULN. There were 38 (36.9%) patients who had ALT levels that remained > ULN over six months, and 21 (20.4%) patients experienced at least two episodes of ALT elevations. In 15 (14.6%) patients, elevated ALT levels were associated with increased HBV replication (i.e. HBV DNA > 2 000 IU/mL) and these were considered as CHB. However, elevation of ALT levels, even in the absence of HBV replication, increased the risk for the development of CHB up to 8-fold in prospective follow-ups. HBsAg seroclearance, cirrhosis, and hepatocellular carcinoma were detected in 43 (10.8%), 4 (1%), and 1 (0.25%) patients, respectively.

Conclusions:

Fluctuations in serum ALT levels may change the prognosis of a HBV inactive carrier state.
