Abstract:
The infectivity of asymptomatic HBsAg carriers' blood was studied in 36 recipients.Their positive rate of anti-HBs was 56.2% before transfusion. After transfusion hepatitis B developed in 2 recipients and SGPT became abnormal in 4(11.1%) of the 36 recipients. The anti-HBs became positive in 83.3% (10/12). The incidence of hepatitis B among blood recipients was lower than that of Western Europe and North America, but similar to that in Southeast Asia. The overall infection rate of HBV was higher than that of the other localities. The infectivity of asymptomatic HBsAg carriers' blood correlated well with the titer of HBsAg. There was no apparent changes in the titer of HBsAg in all the 3 recipients with positive HBsAg before transfusion.No new HBsAg carriers developed in 36 recipients.
