Sanded nuclei, previously linked to Hepatitis B, were found to be associated with Hepatitis Delta Virus (HDV) infection in immunosuppressed patients. This study reveals a novel link between sanded nuclei and HDV, challenging prior understanding.

Area of Science:

  • Hepatology
  • Virology
  • Pathology

Background:

  • Sanded nuclei are eosinophilic inclusions observed in liver cells during chronic Hepatitis B virus (HBV) infection.
  • These inclusions are morphologically characterized by a homogeneous, finely granular texture, resembling sand.
  • They have been historically associated with excessive Hepatitis B core antigen production.

Observation:

  • The study examined liver biopsies from two immunosuppressed patients positive for Hepatitis B surface antigen (HBsAg).
  • These patients presented with numerous sanded nuclei, similar in appearance to those seen in HBV infection.
  • Immunohistochemical analysis revealed strong nuclear positivity for delta antigen within the sanded nuclei.

Findings:

  • Sanded nuclei in these patients were negative for Hepatitis B core antigen.

  • Hepatitis B core particles were not detected using electron microscopy.
  • The study establishes a novel association between sanded nuclei and Hepatitis Delta Virus (HDV) infection.

    • Implications:

    • This research suggests that sanded nuclei may serve as a potential diagnostic indicator for HDV infection.
    • It expands the understanding of the morphological manifestations of viral hepatitis.
    • Further research is warranted to confirm this association and explore its diagnostic utility in a broader patient cohort.
