The HBsAg, anti-HBs, anti-HIV, and anti-HCV results were evaluated separately for each year (Table 2, Figure 1).
These household contacts were offered HBV testing, and those whose test results were HBsAG-positive were linked to care; persons whose test results were HBsAG-negative with positive anti-HBs results (indicative of immunity through immunization or resolved infection) were reassured; and persons whose test results were negative for all three HBV seromarkers (susceptible to infection) were offered hepatitis B vaccination (3-dose series over 6 months).
All of the anti-HBc positive samples were tested for anti-hepatitis B surface antibodies with the anti-HBs kit (Bio-Rad, Marnes-la-Coquette, France).
Follow-up annual anti-HBs levels were performed, booster vaccinations of hepatitis B vaccine 40 mcg given intramuscularly were administered every year up to three years, if anti-HBs levels were <10 mlU/mL.
The demographic characteristics; the pretreatment Eastern Cooperative Oncology Group (ECOG) score; Ann Arbor staging; histology; number of rituximab cycles; serum anti-HBc, anti-HBs, and HBV DNA levels; and serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TB), lactate dehydrogenase (LDH), and albumin levels and changes were recorded for each of the 98 HBsAg-negative patients.
Sobre a situacao imunologica, apesar de os niveis de anti-HBs nao terem sido medidos entre os participantes, foi possivel investigar a resposta acerca da realizacao do exame sorologico (anti-HBs) apos vacinacao.
Due to their occupational increased risk of contracting HBV, screening and vaccination to all HCWs to maintain an anti-HBs > 10 mIU/mL are recommended and for those who are HBsAg positive a potent antiviral agent should be provided to maintain the HBVDNA < 2000 IU/mL.
Twenty-five patients (19%) were positive for anti-HBc, while 99 (71%) were immune with anti-HBs level above 10IU/ml.
Blood tests were drawn for checking Anti-HBs titer of 101 vaccinated subjects including dental students, practicing dentists/ faculty and paramedics.
Only 50.17% of the participants had been tested for hepatitis B surface antibody (anti-HBs) previously.
OBI infektivitesi tranfuzyon yapilan plazma hacmi ile anti-HBs ve alicinin immun yanit duzeyine bagli olup, bilindigi uzere serolojik markerler (belirtecler) acisindan salt anti-HBc'li HBV DNA pozitif donorler (%10-20) salt anti-HBs tasiyicilarina (<%5) oranla daha infektif kabul edilir (59).
