Objective: To investigate hepatitis B virus DNA in the cerumen of hepatitis B virus infected patients.
Methods: This study comprised 30 confirmed cases of chronic hepatitis B. Patients' serum samples were examined for hepatitis B surface antigen and antibodies using enzyme immunoassay systems. The presence of hepatitis B virus DNA in cerumen was investigated using a polymerase chain reaction test.
Results: All of the samples were positive for hepatitis B surface antigen and negative for hepatitis B surface antibodies. Hepatitis virus DNA was detected in two cerumen samples (6.6 per cent of patients).
Conclusion: Cerumen can be a potential source of transmission of hepatitis B virus.
