Table 1. HBV markers and alanine aminotransferase (ALT) levels in HBV-infected children and their mothers.
| Sample | Mother | Child | ||||||||
| Age (years) | HBsAg (IU/ml) | HBeAg (S/CO) | ALT (U/L) | HBV DNA (IU/ml) | Age (months) | HBsAg (IU/ml) | HBeAg (S/CO) | ALT (U/L) | HBV DNA (IU/ml) | |
| D24L | 26 | 76520 | 1286 | 22 | 4.32×107 | 12 | 85090 | 1282 | 66.9 | 1.85×107 |
| D24S | 12 | 159350 | 1408 | 59.9 | 2.41×107 | |||||
| F51 | 31 | 49760 | 1168 | 25 | 9.2×107 | 24 | 9690 | 922 | 253 | 7.98×105 |
All three children were female, and children D24L and D24S were twins. Each subject was positive for anti-HBc. Phylogenetic analysis showed that all subjects were infected with HBV genotype B.
