Methods We enrolled all patients tested for HBV serological markers, such as HBV surface antigen （HBsAg）, HBV surface antibody （HBsAb）, hepatitis B e antigen （HBeAg）, hepatitis B e antibody （HBeAb）, HBV core antibody （HBcAb）, and HBV-DNA from July 2008 to July 2009 in Peking Union Medical College Hospital. The positive rate of each HBV serological marker was calculated according to gender, age, and department, respectively. The positive rates of HBV-DNA among patients with positive HBsAg were also analyzed. Results Among 27 409 samples included, 2681 （9.8%） were HBsAg positive. When patients were divided into 9 age groups, the age-specific positive rate of HBsAg was 1.2%, 9.6%, 12.3%, 10.9%, 10.3%, 9.7%, 8.0%, 5.8%, and 4.3%, respectively. The positive rate of HBsAg in non-surgical department, surgical department, and health examination center was 16.2%, 5.8%, and 4.7%, respectively. The positive rate of HBsAg of males （13.3%） was higher than that of females （7.3%, P=0.000）. Among the 2681 HBsAg （＋） patients, 1230 （45.9%） had HBV-DNA test, of whom 564 （45.9%） were positive. Patients with HBsAg （＋）, HBeAg （＋）, and HBcAg （＋） result usually had high positive rate of HBV-DNA results （71.8%, P=0.000）. Conclusions Among this group of patients in our hospital, the positive rate of HBsAg was relatively high. Age group of 20-29, males, and patients in non-surgical departments were factors associated with high positive rate of HBsAg.展开更多

Methods We enrolled 290 newborns and their hepatitis B surface antigen(HBsAg) positive mothers. HBV cccDNA in PBMC and HBV DNA in serum were detected by a real‐time PCR‐TaqM an probe while HBV serological markers were detected with an electrochemiluminescence immunoassay. Results There was a positive correlation between the levels of PBMC HBV cccD NA and serum HBV DNA and HBeA g(r = 0.436 and 0.403, P < 0.001). The detection rate of pattern A [‘HBsA g(+), HBeA g(+), and anti‐HBc(+)’] was significantly higher in the PBMC HBV cccD NA positive group than in the control group(χ^2 = 48.48, P < 0.001). There was a significant association between HBV intrauterine transmission and PBMC HBV cccD NA(χ^2 = 9.28, P = 0.002). In the presence of serum HBV DNA, HBeA g, and PBMC HBV cccD NA, the risk of HBV intrauterine transmission was three times higher(OR = 3.69, 95% CI: 1.30‐10.42) than that observed in their absence. The risk of HBV intrauterine transmission was the greatest(OR = 5.89, 95% CI: 2.35‐14.72) when both PBMC HBV cccD NA and pattern A were present. A Bayesian network model showed that maternal PBMC HBV cccD NA was directly related to HBV intrauterine transmission. Conclusion PBMC HBV cccDNA may be a direct risk factor for HBV intrauterine transmission. Our study suggests that serological markers could be combined with PBMC‐related markers in prenatal testing.展开更多

METHODS： All individuals with the pattern ＂anti-HBc alone＂ were registered over a time span of 82 mo. HBVDNA was measured in serum and liver samples, and clinical charts were reviewed. RESULTS： Five hundred and fifty two individuals were ＂anti-HBc alone＂ （of 3004 anti-HBc positive individuals; 18.4%）, and this pattern affected males （20.5%） more often than females （15.3%; P〈0.001）. HBV-DNA was detected in serum of 44 of 545 ＂anti-HBc alone＂ individuals （8.1%）, and in paraffin embedded liver tissue in 16 of 39 patients tested （41.0%）. There was no association between the detection of HBV genomes and the presence of biochemical, ultrasonic or histological signs of liver damage. Thirty-eight ＂anti-HBc alone＂ patients with cirrhosis or primary liver carcinoma had at least one additional risk factor. HCV-coinfection was present in 20.4% of all individuals with ＂anti-HBc alone＂ and was the only factor associated with a worse clinical outcome. CONCLUSION： In an HBV low prevalence area, no evidence is found that HBV alone causes severe liver damage in individuals with ＂anti-HBc alone＂. Recommendations for the management of these individuals are given.展开更多
