The study of IgG subclass profiles of anti-hbc in populations with different status of HBV infection.
To study IgG subclasses for the hepatitis B virus (HBV) core antigen (anti-HBc) in different populations, a comparison was made between 104 chronic carriers (60 male and 44 female) and 434 recovered individuals (247 male and 192 female). Biochemistry analyses of AST (aspartate aminotransferase) and ALT (alanine aminotransferase) were also performed. Among the 104 chronic carriers, 21 patients were found to be ALT and AST abnormal (> 25 IU/ml). After comparing these ALT and AST abnormal patients with other ALT and AST normal chronic carriers, no statistical difference was observed in the OD values of the anti-HBe (p > 0.05). The ELISA results showed the anti-HBc IgG subclass pattern was IgG1 > IgG3 > IgG4 in chronic carriers and IgG3 > IgG1 > IgG4 in recovered individuals (p < 0.05). This result suggests the IgG1/IgG3 ratio may be related with HBV status. However, in spite of the different anti-HBc IgG1/IgG3 patterns demonstrated in different populations, both anti-HBc IgG1 and IgG3 concentrations were significantly higher in chronic carriers (p < 0.05). Therefore, both the anti-HBc IgG1/IgG3 ratio and their amounts differed. They may play a significant role in chronic carriers and recovered individuals. The anti-HBc IgG subclass profiles of chronic carriers were not changed regardless of liver inflammation, and were independent of sex and age.
