In recent years the group of inactive carriers and that of occult hepatitis B virus infection could become a main concern due to their epidemiological and clinical significance. At present, our top priority consists of identifying, prophylaxis and monitoring of these patients undergoing immunosuppressive treatment.

Anti-HBc positivity is a frequent cause of donation rejection at blood banks. Hepatitis B virus (HBV) infection may also occur in HBsAg-negative patients, a situation denoted occult infection. Similarly, very low levels of HBV-DNA have also been found in the sera of patients with chronic hepatitis C virus (HCV) infection, even in the absence of serum HBsAg. Initially we searched for HBV-DNA in ...
BACKGROUND Hepatitis B surface antigen (HBsAg)-negative but hepatitis B virus (HBV) DNA-positive infection-known as occult hepatitis B infection (OBI)-occurs in 1% to >15% of HIV-positive individuals in the United States and South Africa, respectively.
