Evolution of HBeAg/Anti-HBe Status and Its Relationship to Clinical and Histological Outcome in Chronic HBV Carriers in Childhood

Fifty-five Japanese HBV carriers under 15 yr of age were followed for 12 months or longer, during which time we investigated the evolution of HBeAg/anti-HBe status and clinical and histological aspects of the liver disease. Of 45 cases positive for HBeAg at the initial examination, 34 remained positive for HBeAg during the follow-up periods, while the remaining 11 lost HBeAg and eight of these seroconverted to anti-HBe. At the final observation, HBeAg positivity in serum was found in as many as approximately 90% of the HBV carriers under 6 yr, but had fallen to 48% in carriers between 12 and 15 yr. The serum transaminase values in 11 cases who lost HBeAg were abnormally elevated for variable periods, but eventually returned to normal. In six of these 11 who had liver dysfunctions, liver biopsy was performed during the HBeAg positive phase or shortly after the disappearance of HBeAg. The histologies of liver were chronic persistent hepatitis in two cases and chronic active hepatitis in four. Repeat liver biopsies of two cases with chronic active hepatitis at the first examination showed nonspecific reactive hepatitis 2 and 4 yr after seroconversion or disappearance of HBeAg. These results indicate that HBeAg-positive HBV carriers with overt liver dysfunctions in childhood are prone to lose HBeAg or to seroconvert to anti-HBe, followed by a marked histological regression, and therefore that special antiviral therapy is probably unnecessary.     

Long-term follow-up of patients with hepatitis B e antigen negative chronic hepatitis B

Background and Aim: After hepatitis B virus (HBV) e antigen (HBeAg) seroconversion, HBV‐DNA continues to replicate, and HBeAg‐negative patients still face the risk of liver disease progression. We investigated the predictive factors for alanine aminotransferase (ALT) elevation, antiviral drug use, and hepatocellular carcinoma (HCC) occurrence in HBeAg‐negative patients. Methods: Age, sex, ALT, platelet counts, HBV‐DNA levels, genotype, antidiabetic drug use, body mass index, smoking, and alcohol consumption were analyzed for a total of 244 HBV carriers who were HBeAg‐negative. Results: Of 244 HBeAg‐negative patients, 158 (64.8%) showed normal ALT levels at baseline. Multivariate Cox hazard regression analysis identified high HBV‐DNA levels and high ALT at baseline as independent risk factors for ALT elevation in the patients with normal ALT at baseline. The threshold ALT and HBV‐DNA levels were determined to be 31 IU/L and 5.3 logcopies/mL, respectively. Seventeen (7.0%) patients used antiviral drugs. Multivariate Cox hazard regression analysis identified high HBV‐DNA levels (threshold, 5.7 log copies/mL), the use of antidiabetic drugs, and daily alcohol consumption at baseline as an independent risk factor for the use of antiviral drugs in HBeAg‐negative patients. In 10 patients (4.1%), HCC was detected, and a low platelet count (threshold, 10.0 × 10⁴/mm³) was associated with the occurrence of HCC. Conclusion: This study identified predictors of future active liver disease in HBeAg‐negative patients, i.e. ALT elevation, unavoidable use of antiviral drugs, and occurrence of HCC.     

慢性肝病患者肝纤维化血清学指标与肝组织纤维化分期的量化关系

Prediction of response to entecavir therapy in patients with HBeAg-positive chronic hepatitis B based on on-treatment HBsAg, HBeAg and HBV DNA levels

Summary. Quantitative hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) assays are emerging as effective tools of on‐treatment predictors of response to antiviral agents, in addition to monitoring serum HBV DNA levels. However, the dynamic relationship between quantitative HBsAg, as well as HBeAg and HBV DNA, and the predictability of subsequent clinical outcomes during entecavir (ETV) therapy remain unclear. Eighty‐two patients with HBeAg‐positive chronic hepatitis B (CHB) received ETV therapy for ≥3 years. Virologic response (VR) after 3 years of ETV therapy was achieved in 73 (89.0%) patients. Among baseline and on‐treatment factors, on‐treatment HBV DNA levels performed better with respect to the prediction of response than HBsAg and HBeAg levels. Especially, the performance of absolute values of HBV DNA with respect to response was superior to HBV DNA decline from the baseline. The best predictive value was an absolute HBV DNA level of 2.3 log₁₀ IU/mL at month 6 (areas under the curve [AUROC], 0.977; 95% CI, 0.940–1.000; P < 0.001). HBeAg seroconversion after 3 years of therapy was achieved in 26 (31.7%) patients. On‐treatment HBeAg levels performed better with respect to the prediction of seroconversion than HBsAg and HBV DNA levels. The best cut‐off value for the HBeAg level at month 12 for the prediction of seroconversion was 0.62 log₁₀ PEIU/mL. Although the HBsAg level at baseline is often used to predict the antiviral potency of entecavir, on‐treatment HBV DNA and HBeAg levels are more helpful for prediction of subsequent clinical outcomes in HBeAg‐positive CHB patients with entecavir treatment.     

The value of quantiative detection of HBV-DNA amplified by PCR in the study of hepatitis B infection

Background/Aims: This study aimed to evaluate the usefulness of quantifying HBV-DNA amplified by polymerase chain reaction in chronic hepatitis B infection.Methods: Serum samples were obtained from 32 asymptomatic HBV carriers and 99 chronic hepatitis B patients (62 positive for anti-HBe and 37 positive for HBeAg). In addition, serial serum samples were analyzed from 15 HBeAg positive patients undergoing antiviral therapy and 17 anti-HBe positive patients with precore mutation. HBV-DNA quantification was carried out using an enzyme immunoassay with an HBV-DNA plasma standard.Results: The digoxigenin-incorporated polymerase chain reaction method detected HBV-DNA in 34.3% of the asymptomatic HBV carriers with a median HBV-DNA concentration of about 0.18×10⁵ mol/ml (range 0.08–0.4), in 87%, of the anti-HBe positive chronic hepatitis cases with a range of 0.2 to >2×10⁵ mol/ml and in 100% of the HBeAg positive patients, with a value in all cases over 2×10⁵ mol/ml. We observed that after treatment, HBV-DNA tested negative in only two of the eight HBeAg positive chronic hepatitis patients who seroconverted to anti-HBe, and was positive in the seven remaining, with a median HBV-DNA value of about 0.2×10⁵ mol/ml (0.09–0.4). In the precore mutants HBV-DNA values ranged from 0.2 to >×10⁵ mol/ml.Conclusions: Polymerase chain reaction HBV-DNA quantification is a sensitive method for managing chronic hepatitis B patients, especially those with low viremia, and may be a valuable tool for evaluating the efficacy of antiviral therapy.     

Hep B Moms: A cross‐sectional study of mother‐to‐child transmission risk among pregnant Asian American women with chronic hepatitis B in New York City, 2007‐2017

Mother‐to‐child transmission (MTCT) is responsible for the majority of chronic hepatitis B virus (HBV) infections worldwide. Despite timely HBV immunoprophylaxis of neonates, MTCT can occur in infants born to mothers with high levels of HBV viremia. We performed a retrospective cross‐sectional analysis of Asian American women with chronic HBV evaluated with HBV DNA during prenatal care at two community health sites in New York City from 2007 to 2017. We described patient's demographic and clinical characteristics, categorized their HBV disease phase and analysed for variables associated with high MTCT risk (defined by HBV DNA level >200 000 IU/mL) using multivariable logistic regression. A total of 1298 pregnancies among 1012 mostly China‐born (97.6%) women with chronic HBV were included in the study. Of the 1241 pregnancies among women not on antiviral treatment, 22.4% were considered high risk for MTCT and, of these, 255 (91.7%) were HBV e antigen (HBeAg)‐positive and 19 (6.8%) were HBeAg‐negative. HBeAg‐positive status and ALT levels between 26 and 50 U/L were associated with higher likelihood for being high risk for MTCT. Only 0.8% of pregnancies low risk for MTCT were in the immune active phase while the majority (58.4%) were in the inactive chronic HBV phase of infection. Approximately one in five (22.4%) pregnancies among Asian American women with chronic HBV was considered high risk for MTCT and met criteria for antiviral therapy. Full assessment of HBV pregnant women and early coordinated care is needed to deliver interventions to prevent MTCT during critical windows of time.
