To assess the hepatitis B virus (HBV) serologic status of hospital health care personnel in Lome. From June 1 to August 31, 2007, 100 workers vaccinated against HBV and 50 unvaccinated workers participated in this comparative cross-sectional study. The data studied were: age, sex, vaccination status, history of accidental exposure to blood, and enzyme-linked immunoassay results for HBs antigen (Ag), total anti-HBc antibodies (Ab), and anti-HBs Ab. Vaccinated subjects had a mean age of 33.2 ± 8.2 years and unvaccinated subjects of 35.2 ± 9.6 years; their respective sex ratios (M:W) were 2:1 and 3:1. Protective levels (>10 IU/L) of anti-HBs Ab were found in 78% (n = 78) of vaccinated subjects compared with 44% (n = 22) of those unvaccinated. HBs Ag was found in 36% (n = 36) of vaccinated and 56% (n = 28) of unvaccinated subjects. Of subjects previously accidentally exposed to blood, 67% (n = 35) had HBs Ag compared with 30% (n = 29) of those subjects without such exposure. This study has proved the high prevalence of HBs Ag carrier status among health care workers in Lome and confirms the importance of vaccination against HBV. |
