The effect of hepatitis B immune globulin (HBIG) combined with hepatitis B vaccine on blocking hepatitis B virus (HBV) transmission between mother and infant and its effect on immune cells were studied. Ninety newborn infants confirmed to be HBV surface antigen (HBsAg)-positive were divided equally into three groups. Group A newborns received the hepatitis B vaccine at 0, 1 and 6 months after birth (10 µg/time). Group B newborns received an intramuscular injection of 100 IU HBIG 2 h after birth before the same treatment as group A. Mothers of group C newborns received three gluteus maxinus injections of 200 IU HBIG. The newborns in group C got the same treatment as group B. The blocking effect of HBV transmission between mother and infant was evaluated, and cell immune function was assessed. There were significant differences in comparison of blocking success rates between group A and B, and between group A and C as well (p<0.05). At the end of 12 months follow-up, the CD4+ level and CD4+/CD8+ ratio in group C were higher thanthose in group A and B (p<0.05). In addition, the level of CD8+ T lymphocyte in group C was lower than those in group A and B (p<0.05). In comparison of levels of CD4+T lymphocyte at the end of 12 months follow-up and 24 h after birth, the differences were significant (p<0.05) in bothgroup B and C. The differences of IFN-γ levels betweengroups B/C and group A were significant (p<0.05). Forthose newborn infants born to mothers who were positivefor both HBsAg and HBeAg, HBIG intervention formothers during late pregnancy, together with combinedtreatment of HBIG and hepatitis B vaccine for infants, gavebetter blocking result of HBV transmission.
