Summary
Hepatitis delta virus (HDV) infection is rare in HBsAg-positive patients in this region. This study found HDV in only 3 out of 118 biopsies, indicating a low prevalence of HDV among carriers.
Area of Science:
- Hepatology
- Virology
- Immunopathology
Context:
- Hepatitis delta virus (HDV) requires hepatitis B virus (HBV) for replication.
- HDV infection can worsen chronic hepatitis and lead to fulminant liver disease.
- Geographic variations in HDV prevalence exist, with higher rates reported in southern Italy.
Purpose:
- To determine the prevalence and pathogenic role of HDV infection in HBsAg-positive patients in a specific geographic area.
- To investigate the occurrence of HDV in liver biopsies from individuals positive for the hepatitis B surface antigen (HBsAg).
Summary:
- 118 liver biopsies from HBsAg-positive patients were analyzed using immunofluorescence microscopy.
- HDV was identified in 3 biopsies exhibiting histological features of chronic active hepatitis.
- The study concludes that HDV infection is infrequent among HBsAg carriers in the examined region.
Impact:
- Provides crucial epidemiological data on HDV prevalence in a local context.
- Contributes to understanding the geographic distribution and rarity of HDV co-infection.
- Highlights the importance of diagnostic testing for HDV in HBsAg carriers, even in low-prevalence areas.
