ABSTRACT
<p><b>OBJECTIVE</b>To explore the association of serum HBV DNA level with HBV-specific and nonspecific cytotoxic T lymphocytes (CTL) in patients with HBV-induced hepatic cirrhosis.</p><p><b>METHODS</b>120 patients with HBV-induced hepatic cirrhosis who were positive for HBV DNA, HBeAg and human leucocyte antigen (HLA)-A2 were enrolled in this study. The level of HBV DNA was determined by real time fluorescence quantitative polymerase chain reaction (PCR). HBV-specific and nonspecific CTL were detected by flow cytometry. Liver function tests were done in the 120 patients. The 120 patients were divided into group A and B based on their HBV DNA levels. In group A, there were 68 patients with HBV DNA level of 3-4 log10 copy/ml, and in group B, 52 with 5-6 log10 copy/ml. HBV-specific and nonspecific CTL and liver function were compared between the two groups.</p><p><b>RESULTS</b>HBV DNA levels were (3.68 +/- 0.19) and (5.97 +/- 0.32) log10 copy/ml in Group A and B respectively with P < 0.001. HBV-specific CTL was higher in group A (0.33% +/- 0.04%) than in group B (0.11% +/- 0.01%) with P < 0.001. HBV-nonspecific CTL were (11.99% +/- 1.51% ) and (11.91% +/- 1.61%) in group A and B respectively with P > 0. 05.</p><p><b>CONCLUSION</b>The level of serum HBV DNA is related to the levels of HBV-specific CTL in patients with HBV-induced hepatic cirrhosis. Patients with higher HBV DNA had lower levels of HBV-specific CTL, and the damage to liver function was severe because of higher levels of HBV DNA. Patients with lower HBV DNA had higher levels of HBV-specific CTL which predict good anti-viral effect.</p>
