    Summary

    Hepatitis B e-antigen presence correlates with disease severity in acute hepatitis B patients. Preliminary serum concentration enhanced detection rates, while e-antigen antibodies were absent during acute infection.

    Area of Science:

    • Hepatology
    • Virology
    • Immunology

    Background:

    • Hepatitis B virus (HBV) infection poses a significant global health challenge.
    • Hepatitis B e-antigen (HBeAg) is a key marker in HBV infection dynamics.
    • Understanding HBeAg and its antibody's role is crucial for disease management.

    Purpose of the Study:

    • To determine the prevalence of HBeAg and anti-HBe in various hepatitis B patient groups.
    • To investigate the correlation between HBeAg presence and hepatitis B severity.
    • To assess the impact of preliminary serum concentration on HBeAg detection.

    Main Methods:

    • Assayed HBeAg and anti-HBe in 233 subjects: acute hepatitis B patients, chronic hepatitis patients, and asymptomatic HBsAg carriers.
    • Utilized preliminary blood serum concentration to enhance antigen detection.
    • Analyzed correlations between HBeAg, clinical presentation, and demographic factors.

    Main Results:

    • Preliminary serum concentration increased HBeAg detection in acute hepatitis B (33.3%) and carriers (1.7%).
    • No anti-HBe antibodies were detected during the acute phase of hepatitis B.
    • A direct correlation was observed between HBeAg positivity and hepatitis B severity, excluding fatal cases.

    Conclusions:

    • HBeAg detection is enhanced by preliminary serum concentration, aiding diagnosis.
    • The absence of anti-HBe in acute hepatitis B suggests a specific immune response phase.
    • HBeAg positivity serves as a reliable indicator of hepatitis B severity, guiding clinical assessment.
