Determinants of spontaneous surface antigen loss in hepatitis B e antigen-negative patients with a low viral load

Loss of hepatitis B surface antigen (HBsAg) usually indicates the cure of hepatitis B virus (HBV) infection. In spontaneous hepatitis B e antigen (HBeAg) seroconverters, lower serum HBsAg and HBV DNA levels have been shown to be associated with HBsAg loss over time. However, little is known about their impacts on HBsAg loss in HBeAg-negative patients with limited viral replication. A total of 688 HBeAg-negative patients with baseline serum HBV DNA levels <2000 IU/mL were enrolled in Taiwan. The relationships of HBsAg and HBV DNA levels with subsequent HBsAg loss were investigated. In a mean follow-up of 11.6 years, the average annual rate of HBsAg loss was 1.6%. Baseline HBsAg and HBV DNA levels were inversely associated with subsequent HBsAg loss. When compared to patients who had HBsAg levels >1000 IU/mL, the rates of HBsAg loss were significantly higher in patients with HBsAg levels of 100-999, 10-99, and <10 IU/mL, with hazard ratios of 2.5 (95% confidence interval [CI], 1.6-4.0), 2.8 (95% CI, 1.6-5.0), and 13.2 (95% CI, 8.1-21.5), respectively. Multivariate analysis showed that HBsAg level, but not HBV DNA, remained as an independent factor. The adjusted hazard ratio of HBsAg loss was 13.2 (95% CI, 7.8-22.1) for HBsAg level <10 versus ≥ 1000 IU/mL. When compared to HBV DNA level by receiver operating characteristic curve analysis, HBsAg level served as a better predictor of both 5-year and 10-year HBsAg loss. CONCLUSION: In HBeAg-negative patients with HBV genotype B or C infection who have HBV DNA level <2000 IU/mL, HBsAg level <10 IU/mL is the strongest predictor of HBsAg loss.     

Quantitative serum HBsAg and HBeAg are strong predictors of sustained HBeAg seroconversion to pegylated interferon alfa‐2b in HBeAg‐positive patients

Background and Aim: To evaluate the usefulness of quantitative hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) for predicting HBeAg seroconversion in chronic hepatitis B patients treated with conventional interferon (IFN) alfa‐2b or PegIFN alfa‐2b. Methods: Fifty‐eight patients were enrolled; 29 for the training group and 29 for the validating group. Quantification of HBsAg and HBeAg was carried out at baseline, week 12, week 24, and then again at 12 and 24 weeks follow up, respectively, for two groups. Sixteen patients in the training group were followed up for 5 years. Results: The cutoff of 1500 IU/mL in serum HBsAg at week 12 had a positive predictive value (PPV) of 33% and a negative predictive value (NPV) of 91%, and 2890 IU/mL at week 24 had a PPV of 43% and an NPV of 95% for HBeAg seroconversion at week 48. The cutoff of 17.55 Paul Ehrlich Institute units/mL (PEI‐U/mL) in serum HBeAg at week 12 had a PPV of 38% and an NPV of 95%, and 8.52 PEI‐U/mL at week 24 had a PPV of 44% and a NPV of 100% for HBeAg seroconversion at week 48. Moreover the HBsAg and HBeAg levels of PegIFN alfa‐2b group were lower than those of the conventional IFN alfa‐2b group. During follow up, patients with HBeAg seroconversion remained HBeAg negative and none of them progressed to cirrhosis, but among the patients with non‐HBeAg seroconversion, two progressed to cirrhosis. Two additional patients with negative HBeAg were observed. Conclusions: On‐treatment serum HBsAg and HBeAg had high predictive values to predict sustained HBeAg seroconversion by PegIFN alfa‐2b. Patients who cleared HBeAg had better survival free of hepatic complications during long‐term follow‐up study.     

慢性乙型肝炎治疗中影响HBeAg转阴和定量的有关因素分析

背景：慢性乙型肝炎抗病毒治疗的完全应答包括血清HBVDNA低于检测水平和HBeAg血清学转换,HBeAg是评估乙型肝炎治疗效果和停药的监测指标。目的：探讨替比夫定治疗HBeAg阳性慢性乙型肝炎患者时影响HBeAg转阴的因素。方法：采用替比夫定治疗156例HBeAg阳性慢性乙型肝炎患者48周,观察ALT、HBVDNA、HBeAg治疗前后变化,分析治疗前基线HBVDNA载量、ALT水平、HBVDNA降至检测下限的时间对HBeAg转阴和定量的影响。结果：替比夫定治疗48周后,HBVDNA转阴128例（82．1％）,ALT恢复正常153例（98．1％）,HBeAg转阴52例（33．3％）;HBVDNA载量、HBeAg定量、ALT水平均显著降低（P〈0．01）。治疗前HBVDNA〈10^7 copies／mL、ALT≥200U／L组的HBeAg转阴率分别显著高于HBVDNA≥10^7 copies／mL、ALT〈200U／L组（46．4％对23．0％,P〈0．01;55．2％对16．9％,P〈0．叭）,且HBeAg定量显著降低（P〈0．01）。HBVDNA降至检测下限的不同时间组HBeAg转阴率和定量相比差异均有统计学意义（P〈0．05）。结论：基线HBVDNA〈10^7 copies／mL、ALT水平较高、治疗后HBVDNA降至检测下限的时间对替比夫定治疗48周时HBeAg转阴和定量具有明显的影响。

A large case-control study on the predictability of hepatitis B surface antigen levels three years before hepatitis B surface antigen seroclearance

The kinetics of hepatitis B surface antigen (HBsAg) levels preceding spontaneous HBsAg seroclearance has not been fully investigated. The kinetics of HBsAg and hepatitis B virus (HBV) DNA of 203 treatment-na?ve, hepatitis B e antigen (HBeAg)-negative patients with spontaneous HBsAg seroclearance were compared with 203 age- and sex-matched HBeAg-negative controls. Serum samples at 3 years, 2 years, 1 year, and 6 months before HBsAg seroclearance and at the time of HBsAg loss were tested. Median HBsAg levels at these respective time points before HBsAg seroclearance were 23.5, 3.51, 0.524, and 0.146 IU/mL. For all time points, patients with HBsAg seroclearance had significantly lower median HBsAg and HBV DNA levels, compared to those of the controls (all P < 0.001). Median HBsAg and HBV DNA levels declined significantly until HBsAg seroclearance (P < 0.001). Although median HBsAg levels also decreased significantly with time (P = 0.006) in controls, median HBV DNA levels remained similar (P = 0.414). Serum HBsAg levels, followed by HBsAg log reduction, were the best predictors of HBsAg seroclearance, with an area under the receiving operator characteristic (AUROC) of 0.833 (95% confidence interval [CI]: 0.792-0.873) and 0.803 (95% CI: 0.755-0.849), respectively. The optimal cut-off HBsAg level and HBsAg reduction to predict HBsAg seroclearance were <200 IU/mL (sensitivity, 84.2%; specificity, 73.4%) and 0.5 log IU/mL/year (sensitivity, 62.8%; specificity, 88.7%), respectively. For patients with HBsAg levels ≥200 IU/mL, an annual 0.5-log reduction was highly predictive of subsequent HBsAg seroclearance (AUROC, 0.867; 95% CI: 0.778-0.956). Conclusion: To conclude, serum HBsAg <200 IU/mL and 0.5-log reduction in HBsAg were predictive of HBsAg seroclearance within 3 years of follow-up. These parameters may serve as good indicators for the consideration of treatment duration and cessation for chronic hepatitis B. (HEPATOLOGY 2012;56:812-819).

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.     

The incidence and predictors of HBV relapse after cessation of tenofovir therapy in chronic hepatitis B patients

This study investigates the incidences and predictors of hepatitis B virus (HBV) relapse after tenofovir disoproxil fumarate (TDF) therapy in hepatitis B e antigen (HBeAg)‐positive and ‐negative patients. We retrospectively recruited 143 chronic hepatitis B (CHB) patients without cirrhosis (39 HBeAg‐positive and 104 HBeAg‐negative patients) who were previously treated with TDF and had post‐treatment follow‐up for at least 6 months (median: 55, IQR 36‐85 weeks). All the patients fulfilled the stopping criteria of APASL 2012. The virological and clinical relapse rates at 104 weeks in HBeAg‐positive patients were 66.6% and 59.1%, while they were 72.3% and 55.9%, respectively, in HBeAg‐negative patients. Cox regression analysis revealed that the higher end‐of‐treatment HBsAg levels were an independent factor of virological relapse in HBeAg‐positive and HBeAg‐negative patients. The end‐of‐treatment HBsAg levels of 200 (area under the receiver operating characteristic (AUROC): 0.624) and 80 IU/mL (AUROC: 0.959) were the optimal values for predicting HBV relapse in HBeAg‐positive and HBeAg‐negative patients, respectively. The virological relapse rate at 78 weeks was 14.3% and 19.6% in HBeAg‐positive and HBeAg‐negative patients who achieved HBsAg ≤200 IU/mL and HBsAg ≤80 IU/mL, respectively. Two patients experienced hepatic decompensation upon hepatitis flares, and no patient died after timely retreatment. Seven patients experienced off‐therapy HBsAg loss. The cumulative rates of HBsAg loss at 104 weeks were 45.5% and 59.3% in patients with end‐of‐treatment HBsAg ≤80 IU/mL and ≤50 IU/mL, respectively. In conclusions, the end‐of‐treatment HBsAg levels were a useful marker for predicting HBV relapse in HBeAg‐positive and HBeAg‐negative CHB patients.
