SUMMARY: The aim of this study was to determine the
neopterin levels and peripheral blood lymphocyte subgroups in
HBeAg-positive and -negative chronic hepatitis B patients. A total
of 89 patients were included in the study. The mean serum neopterin
level of patients with chronic hepatitis B was significantly higher
than that of the control group. In HBeAg-positive chronic hepatitis
B patients, the mean serum neopterin level was significantly higher
than that of anti-HBeAb-positive patients. There was no significant
correlation between the serum neopterin levels and alanine aminotransferase
and HBV-DNA levels in HBeAg-positive chronic hepatitis B patients.
There were no significant differences between the control subjects
and patients with HBeAg-positive or anti-HBeAb-positive hepatitis
in terms of the percentage of peripheral blood CD4+ or CD8+ or
the ratio of CD4+/CD8+ lymphocytes. Our results suggest an association
between elevated neopterin concentrations and HBeAg-positivity
in patients with chronic hepatitis B. However, there appears to
be no association between the neopterin levels and either hepatocyte
damage or viral replication status.
