Abstract
AIM: To compare the difference in the frequency of peripheral blood HBcAg-specific cytotoxic T lymphocytes (CTLs) between patients with acute hepatitis B and those with acute episodes of chronic hepatitis B.
METHODS: Seventeen HLA-A2-positive patients with acute hepatitis B and 13 patients with acute episodes of chronic hepatitis B were included in the study. The frequency of peripheral blood HBcAg-specific CTLs was determined by HLA-A2/peptide tetramer staining.
RESULTS: The frequency of peripheral blood HBcAg-specific CTLs ranged from 0.071% to 31.610%. There was a significant difference in the frequency of peripheral blood HBcAg-specific CTLs between patients with acute hepatitis B and those with acute episodes of chronic hepatitis B (9.601% ± 10.425% vs 0.259% ± 0.193%, P = 0.002).
CONCLUSION: There is a significant difference in the frequency of peripheral blood HBcAg-specific CTLs between patients with acute hepatitis B and those with acute episodes of chronic hepatitis B. The frequency of peripheral blood HBcAg-specific CTLs might be a useful parameter to distinguish the above two types of illness.
