Histological staining of hepatitis B antigen in paraffin embedded liver tissue

Area of Science:

• Hepatology
• Virology
• Histopathology

Background:

• Hepatitis B virus (HBV) infection is a significant global health concern.
• Accurate detection of HBV antigens in liver tissue is crucial for diagnosis and management.
• Traditional diagnostic methods may have limitations in detecting chronic carriers.

Purpose of the Study:

• To evaluate the efficacy of Gomori's aldehyde fuchsin, aldehyde thionine, and modified orcein stains in detecting hepatitis B antigen.
• To assess the utility of these histochemical stains as an additional tool for identifying hepatitis B carriers in liver biopsies.

Main Methods:

• A total of 206 unselected liver biopsies were analyzed.
• Biopsies were stained using Gomori's aldehyde fuchsin, aldehyde thionine, and a modified orcein stain (Shikata et al., 1974).
• Cytoplasmic staining patterns were examined for evidence of hepatitis B antigen.

Main Results:

• Six out of 206 liver biopsies (approximately 2.9%) exhibited positive cytoplasmic staining.
• The positive staining was indicative of the presence of hepatitis B antigen within the liver cells.
• The stains demonstrated potential in visualizing viral antigens within the hepatic tissue.

Conclusions:

• Gomori's aldehyde fuchsin, aldehyde thionine, and modified orcein stains are effective in detecting hepatitis B antigen in liver biopsies.
• These histochemical staining methods can serve as valuable adjuncts in the identification of hepatitis B carriers.
• Routine use of these stains in liver biopsy analysis is recommended for improved diagnostic accuracy.
