METHODS: Studies were identified by searching available databases up to January 2011. Inclusive criteria were HBV-carrier mothers who had been involved in randomized controlled clinical trials (RCTs) with lamivudine treatment in late pregnancy, and newborns or infants whose serum hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) or HBV DNA had been documented. The relative risks (RRs) for inerruption of MTCT as indicated by HBsAg, HBV DNA or HBeAg of newborns or infants were calculated with 95% confidence interval (CI) to estimate the efficacy of lamivudine treatment. RESULTS: Fifteen RCTs including 1693 HBV-carrier mothers were included in this meta-analysis. The overall RR was 0.43 (95% CI, 0.25-0.76; 8 RCTs; Phet- erogeneity= 0.04) and 0.33 (95% CI, 0.23-0.47; 6 RCTs; Pheterogeneity = 0.93) indicated by newborn HBsAg or HBV DNA. The RR was 0.33 (95% CI, 0.21-0.50; 6 RCTs; Pheterogeneity = 0.46) and 0.32 (95% CI, 0.20-0.50; 4 RCTs; Pheterogeneity = 0.33) indicated by serum HBsAg or HBV DNA of infants 6-12 mo after birth. The RR (lamivudine vs hepatitis B immunoglobulin) was 0.27 (95% CI, 0.16-0.46; 5 RCTs; Pheterogeneity = 0.94) and 0.24 (95% CI, 0.07-0.79; 3 RCTs; Pheterogeneity = 0.60) indicated by newborn HBsAg or HBV DNA, respectively. In the mothers with viral load 〈 106 copies/mL after lamivudine treatment, the efficacy (RR, 95% CI) was 0.33, 0.21-0.53 (5 RCTs; Pheterogeneity = 0.82) for the interruption of MTCT, however, this value was not significant if maternal viral load was 〉 106 copies/mL after lamivudine treatment (P = 0.45, 2 RCTs), as indicated by newborn serum HBsAg. The RR (lamivudine initiated from 28 wk of gestation vs control) was 0.34 (95% CI, 0.22-0.52; 7 RCTs; Pheterogeneity = 0.92) and 0.33 (95% CI, 0.22-0.50; 5 RCTs; Phetero展开更多

To help standardize the prevention, diagnosis, and treatment of chronic hepatitis B, the Guideline on prevention and treatment of chronic hepatitis B (abbr. Guideline) was created by a group of appropriate experts belonging to the Society of Hepatology and the Society of Infectious Disease, the Chinese Medical Association according to the principles of evidence-based medicine using the latest clinical research data. The evidence used to formulate the recommendation has been classified into 3 classes and 5 grades, which are indicated by Roman numerals in brackets.展开更多

METHODS: Monocytes were isolated from fresh peripheral blood of 19 chronic HBV-infected patients by Ficoil-Hypaque density gradient centrifugation and cultured by plastic-adherence methods. DCs were induced and proliferated in the culture medium with recombinant human granulocyte-macrophage-colony- stimulating factor (rhGM-CSF) and human interleukin-4 (rhIL-4). DCs pulsed with HBsAg for twelve hours were injected into patients subcutaneously twice at intervals of two weeks. Two patients received 100 mg oral lamivudine daily for 12 mo at the same time. HBV-DNA and viral markers in sera of patients were tested every two months. RESULTS: By the end of 2003, 11 of 19 (57.9%) patients had a clinical response to DC-treatment. HBeAg of 10 (52.6%) patients became negative, and the copies of HBV-DNA decreased 101.77±2.39 averagely (t = 3.13, P<0.01). Two cases co-treated with DCs and lamivudine had a complete clinical response. There were no significant differences in the efficient rate between the cases with ALT level lower than 2xULN and those with ALT level higher than 2xULN before treatment (X2 = 0.0026). CONCLUSION: Autologous DC-vaccine induced in vitro can effectively suppress HBV replication, reduce the virus load in sera, eliminate HBeAg and promote HBeAg/anti-HBe transformation. Not only the patients with high serum ALT levels but also those with normal ALT levels can respond to DC vaccine treatment, and the treatment combining DCs with lamivudine can eliminate viruses more effectively.展开更多
