A cautionary note to hepatitis B e antigen (HBeAg)-negative test results in pregnant women in an area prevalent of HBeAg-negative chronic hepatitis B.

ABSTRACT: Maternal hepatitis B e Antigen (HBeAg) positivity poses a risk for hepatitis B virus (HBV) mother-to-child transmission (MTCT). In resource-constrained settings, HBeAg testing is recommended as an alternative to HBV DNA testing to establish antiviral prophylaxis eligibility. Nevertheless, the high prevalence of HBeAg-negative chronic hepatitis B (e-CHB) in many countries should not be overlooked. We studied HBV characteristics and explored the potential MTCT risk among HBeAg-negative/HBsAg-positive expectant mothers in an area prevalent of e-CHB. Among 1348 pregnant mothers screened for HBV infection, 81 (6.0%) were HBsAg-positive. These women were examined for HBeAg, HBV DNA, and cord blood HBV DNA. Sixteen (19.8%) of the HBsAg-positive mothers were HBeAg-positive, whereas 65 (80.2%) were HBeAg-negative, including eight inactive carriers (HBsAg <100 IU/ml, HBV DNA ≤ 2000 IU/ml, and ALT < 40 IU/L). Of the remaining 57 HBeAg-negative mothers, ten revealed HBV Basal Core Promoter or Precore mutations, with three having high viremia (HBV DNA > 200 000 IU/mL), which is associated with a high MTCT risk and therefore qualifies them for antiviral prophylaxis. This pilot study provides a cautionary note to the interpretation of negative HBeAg test results when determining eligibility for MTCT antiviral prophylaxis in situations with limited resources and in regions where e-CHB is prevalent.

Project description:BackgroundHepatitis B surface antigen clearance or seroconversion is rarely achieved for patients using nucleoside analogs or pegylated interferon alpha monotherapy approaches. Several recent studies have confirmed the benefit of a combination of these two approaches for selected chronic hepatitis B patients. However, few reports have investigated long-term outcomes or health economic evaluation for hepatitis B surface antigen clearance. The aim of this study was to perform a cost-effectiveness analysis of the long-term use of this combination strategy among selected hepatitis B e antigen-negative patients.MethodsDrawing on experience in China, we used a Markov model to simulate disease progression among a population of hepatitis B e antigen-negative chronic hepatitis B patients with surface antigen levels of ≤1,000 IU/mL through a discrete series of health states. We compared nucleoside analog monotherapy to the combination strategy over a prolonged period. We measured lifetime costs, quality-adjusted life-years and incremental cost-effectiveness ratios.ResultsThe combination therapy produced 15.8 quality-adjusted life-years, and cost US dollars (USD) 45,032 per patient. The monotherapy gave 13.9 quality-adjusted life-years, and had a cost of USD 52,064. The incremental cost-effectiveness ratio of the monotherapy (USD -3,755 per quality-adjusted life-year) did not obtain extended dominance over combination therapy. The most cost-effective option was combination therapy among patients with hepatitis B surface antigen levels of ≤10 IU/mL, which had the lowest calculated cost of USD 35,318 and most quality-adjusted life-years (16.7).ConclusionsA long-term combination treatment strategy for selected hepatitis B e antigen-negative chronic hepatitis B patients may prolong quality-adjusted life-years compared with nucleoside analog monotherapy. Chronic hepatitis B patients with a hepatitis B surface antigen level of ≤10 IU/mL were the most cost-effective population under this strategy.
