METHODS： Sera from 100 patients with chronic HBV infection and 30 healthy controls were included in this study. The patients were divided into group A [HBsAg （＋）, HBeAg （＋） and anti-HBc （＋）, n = 50] and group B [HBsAg （＋）, HBeAg （＋） and anti-HBc （-）, n = 50]. sIL-2R levels were determined using ELISA. HBV DNA and alanine aminotransferase （ALT） were also detected. RESULTS： Serum sIL-2R levels were significantly higher in patients with chronic HBV infection than in healthy controls. Moreover, serum sIL-2R levels were significantly higher in patients with HBsAg （＋）, HBeAg （＋） and antiHBc （＋） （976.56±213.51×10^3 U/L） than in patients with HBsAg （＋）, HBeAg （＋） and anti-HBc （-） （393.41±189.54 ×10^3 U/L, P〈 0.01）. A significant relationship was found between serum sIL-2R and ALT levels （P〈 0.01） in patients with chronic HBV infection, but there was no correlation between sIL-2R and HBV DNA levels. The anti-HBc status was significantly related to the age of patients （P〈 0.01）. CONCLUSION： The high sIL-2R level is related to positive anti-HBc in chronic hepatitis B patients. Positive anti-HBc may be related to T-lymphocyte activation and negative anti-HBc may imply immune tolerance in these patients.展开更多
