Absence of relationship between Schistosoma japonicum and hepatitis B virus infection in the Dongting lake region, China.
In order to determine whether infection with Schistosoma japonicum is related to a higher rate of infection with hepatitis B virus and/or to a higher probability of HBsAg chronic carriage, a population based survey was carried out in China in which HBV markers were studied in 112 subjects with long-lasting S. japonicum infection, and 93 subjects with no S. japonicum infection 37.5% of the cases and 40.9% of controls showed no markers of HBV infection. The prevalence rate of HBsAg was 12.5% in the cases and 12.9% in the controls. For anti-HBc and anti-HBs the figures were 59.8% and 59.8%, and 27.9% and 35.0%, respectively. These data do not support the hypothesis of an interaction between infection with hepatitis B virus and S. japonicum.
