Epidemiology of occult hepatitis B and C in Africa: A systematic review and meta-analysis
2022, Journal of Infection and Public HealthCitation Excerpt :In the early 1980 s, a new form of clinical hepatitis B virus (HBV) infection was described, corresponding to the presence of HBV DNA in the liver and/or serum of patients in whom the HBs antigen (Ag) is undetectable by the usual serology tests. This was called occult hepatitis B (OBI) [1–3]. Based on the antibody profile of HBV, OBI can be distinguished into seropositive-OBI (anti-HBc and/or anti-HBs positive) and seronegative-OBI (anti-HBc and anti-HBs negative)[4].
Overt and occult hepatitis B infection after neonatal vaccination: mother-to-infant transmission and HBV vaccine effectiveness
2021, International Journal of Infectious DiseasesCitation Excerpt :Thus, our study provides some data on the prevalence of HBV infection among pregnant women born during the period of introduction of HBV vaccination in China. Until now, except for the well-studied type-I transmission based on HBIov and non- HBIov subjects, the other three were poorly studied (Levicnik-Stezinar et al., 2008; Thiers et al., 1988; Yuen et al., 2011). The identification of HBIoc out of non-HBI made the estimate of vaccine effectiveness based on transmission types possible.
When can it be useful to look for occult HBV in haemodialysis patients?
2020, NefrologiaCitation Excerpt :There is no clear information about the risk of transmission in patients with OBI. There are published cases of transmission from blood transfusion with OBI from the 1970s and later, in chimpanzees inoculated with sera from HBsAg-negative individuals.36,37 It has been reported that the risk of transmission of HBV infection in liver recipients from donors HBsAg-negative and anti-HBc-positive serological profiles is reported as 17–94%,38 but there is no data about transmission in HD centres or among other groups affected.
