    Hepatitis B virus (HBV) markers are more prevalent in leprosy patients, particularly lepromatous leprosy, suggesting a link between cell immunity and HBV infection. This study reviews HBV replication markers in leprosy patients.

    Area of Science:

    • Hepatology
    • Infectious Diseases
    • Immunology

    Background:

    • The Australia antigen, now known as Hepatitis B surface antigen (HBsAg), was found at higher rates in leprosy patients in 1966.
    • Initial hypotheses included genetic factors and increased transmission due to hospitalization in lepromatous leprosy.
    • The link between HBsAg and Hepatitis B virus (HBV) shifted focus to immune responses in leprosy.

    Purpose of the Study:

    • To review the connection between cell immunity in leprosy and Hepatitis B.
    • To analyze seric markers of HBV replication in leprosy patients.
    • To explore the incidence of hospitalization and age in relation to HBV markers in leprosy.

    Main Methods:

    • Bibliographical review of approximately fifty published works.

    Related Experiment Videos

  • Inclusion of a personal study analyzing Hepatitis B virus replication markers.
  • Examination of patient data including hospitalization and age.

    • Main Results:

    • Lepromatous leprosy patients show a higher prevalence of HBsAg carriers compared to tuberculoid leprosy and controls.
    • Geographic areas with high leprosy prevalence often overlap with high HBsAg carrier rates.
    • Studies primarily focus on HBsAg detection, with fewer investigating HBeAg and HBsAc.

    Conclusions:

    • Cellular immunity, a key feature of lepromatous leprosy, is a significant factor in the observed association with HBV.
    • The study provides a model for investigating cell immunity and Hepatitis B.
    • Further research is warranted to understand the complex relationship between leprosy and HBV.
