The mean HBsAg and anti-HBs seropositivity rates among pregnant women in Turkey were reported as 4.4% (range: 1.2-12.3%) and 23% (range: 3.7-41.1%), respectively (7,17).
All the serum samples were tested for HBsAg using 3rdgeneration ELISA (Qualisa HBsAg, Qualpro Diagnostics, Goa, India) following standard protocol and manufacturer's instructions with adequate quality control.
HBsAg reductions were similar for NUC naive patients (cohort 8) and NUC experienced patients (cohort 9).
HBV reactivation was defined according to the consensus definition of the Chinese Society of Hematology (Chinese Medical Association), Chinese Anti-Cancer Association, and Chinese Society of Hepatology (Chinese Medical Association).[4] For patients with active HBV infection or inactive carriers (HBsAg positive), reactivation was defined as detectable HBV DNA or ≥1 log[sub]10 of baseline or change in status from HBeAg negative to HBeAg positive.
Among persons whose test results were positive for HBsAg, demographic characteristics, including sex, year of birth, race/ ethnicity, health insurance status, and country of birth were collected, as were HBV-specific linkage-to-care indicators, including documentation of two medical visits (retention in care), and HBV-directed care, including monitoring HBV DNA, alanine aminotransferase, and hepatitis B e antigen (engaged in care).
To further investigate the association among HBsAg, HBV DNA, and flow cytometry results, correlation analyses were used.
These approaches target every stage of the virus life cycle and include direct antivirals such as silencing RNA (siRNA), entry inhibitors, capsid inhibitors, HBsAg inhibitors and cccDNA inhibitors or indirect antivirals such as therapeutic vaccines, "toll like receptor" (TLR) agonists, and cyclofinin inhibitors.
* Infants weighing at least 2,000 g and born to mothers with an unknown HBsAg status: Administer the hepatitis B vaccine within 12 hours of birth and HBIG by hospital discharge or age 7 days (whichever is first) if HBsAg status remains unknown or is confirmed positive.

HBV has been highly endemic in China, where serosurveys in 1979 and 1992 indicated a 10% prevalence of HBV surface antigen (HBsAg) (2,3).
Por su parte, en el estado Anzoategui, la prevalencia se ubica por debajo de la obtenida en otras ciudades de Venezuela (0.4% para HBsAg).
