Results showed that of the 1000 HBsAg-negative donors, 12 (1.2%) were anti-HBc positive/anti-HBs negative and 63 (6.3%) were anti-HBc positive/anti-HBs positive. Additionally, among these 63 anti-HBc positive/anti-HBs positive ... Ahmad Mohammad A - 《Research Journal of Medical Sciences...
This study evaluated the long-term clinical outcomes of the coexistence of HBsAg and anti-HBs. The proportion of HBsAg/anti-HBs double-positive chronic hepatitis B patients was 7.0% among in this study. The coexistence of HBsAg and anti-HBs was associated with a higher HCC risk and more HBsA...
DP patients tend to have a poor clinical outcome The characteristics of all the subjects enrolled in our study were summarized in Table 1. Among the 305 cases of HBsAg and anti-HBs double-positive chronic hepatitis B patients, there was a male-to-female ratio of 1.38:1, with 177 males an...

positive anti-HBs and anti-HBc showed a mild increaseof anti-HBs levels after the 2~(nd) boosting dose (mean anti-HBs level was 320:198 mIU),but the increase of serumanti-HBs titer was much smaller than that in the controlgroup.The averages of their initial serum anti-HBs levelsand ...
Anti-HBc positive donors were stratified by anti-HBs signal strength (sample/cutoff ratio, S/ CO) and the HCV infection rate in each cohort was determined. Results: (see table) Conclusions: Anti-HCV serepositivity in anti-HBc positive donors correlates with undetectable or low levels of anti-...
