Introduction: Simultaneous HBsAg and anti-HBs positivity can be seen in patients with chronic hepatitis B (CHB) infection. The paradoxical phenomenon of ongoing viral replication despite the presence of neutralizing antibodies makes simultaneous HBsAg and anti-HBs positivity one of the most interesting atypical serological profiles. The aim of this study was to investigate the relationship between the coexistence of HBsAg and anti-HBs and S gene mutations in study and control groups with CHB infection.
