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

Studies have consistently showed positive relations between maternal sensitivity and infant attachment security. Warm and harmonious family was also found to be an important factor. On the contrary, parents’ poor marital status and high level of stress in family would result in insecure attachment style in children.展开更多
