Relationship between ABO blood type and multi-infection of hepatitis B virus

  Objective   To study the correlation of ABO blood type and multi infection of hepatitis B virus.

  Methods   1: 1 case control study was conducted to study the correlation of ABO blood type and multi-infection of hepatit is B virus, and a case control study was also conducted to study the correlation of ABO blood type and HBV infection alone.

  Results   There was no significant correlation between ABO blood type and multi infection of hepatitis B virus, and super infection of hepatitis B virus and C virus, and infection of hepatitis B virus(P > 0.05);There was sig nificant correlation between type Oblood and super infection of HBV and HEV(P < 0.05), no other correlation of type blood and super infection of HBV and HEV(P > 0.05).

  Conclusion   There was significant correlation between type O blood and super infection of HBV and HEV, type O bloo was probably the risk factor of the dual infection of HBV and HEV.No other correlation of type blood and multiple virus infection or HBV infection was found.
