Relationship of HBsAg subtypes with HBeAg/anti-HBe status and chronic liver disease. Part I: Analysis of 1744 HBsAg carriers.
A total of 1744 HBsAg carriers were investigated to determine whether there are clinical differences among HBsAg subtypes or not. Although adr was more predominant than adw in 1078 asymptomatic carriers as well as in 666 carriers with liver dysfunction, the adr carriers had liver dysfunction more frequently than the adw carriers (p = 0.005). In addition, the adr carriers were more often positive for HBeAg and less often positive for anti-HBe than the adw carriers (p less than 0.001). Multivariate analyses indicated that the HBsAg subtypes were associated with liver dysfunction not directly but through the relationship between the HBsAg subtypes and HBeAg/anti-HBe status. HBeAg/anti-HBe status of each age bracket in the adr carriers and in the adw carriers suggested that adr carriers are seroconverted later than adw carriers. In conclusion, HBsAg subtypes may affect the development of chronic liver disease, through their association with HBeAg/anti-HBe status.
