ABSTRACT
Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) have a common route like sexually transmitted infections (STIs), vertical transmission and blood transfusion, etc. Therefore, it was necessary to be an attempt to confirm the relationship of HBV and HIV in Korea. We investigated the prevalence of Hepatitis B surface antigen (HBsAg) and Hepatitis B core antibody (anti-HBc) in HIV positive groups (n=430) and HIV negative groups (n=434) from January 2014 to October 2015. When comparing the prevalence of anti-HBc between the two groups, HIV positive group (36.0%) showed a higher prevalence than HIV negative group (24.7%), the result was statistically significant (p < 0.05). However, there was a little difference on HBsAg and not significant. Therefore, by showing a clear difference in anti-HBc between the two groups of HIV in Korea, it was confirmed to be associated with co-infections between Hepatitis B and HIV.
