Background and aims

Hepatitis B virus (HBV) vaccine failure remains a hurdle to the global elimination of HBV infections in the vaccination era. We aimed to elucidate the relationships between HBV entry receptor sodium taurocholate co-transporting polypeptide (NTCP) and vaccine failure in children born to highly infectious mothers.

Methods

The genetic variants rs7154439, rs4646285, rs4646287, and rs2296651 were genotyped in 170 children with chronic HBV infections and 138 control children of mothers positive for hepatitis B e antigen (HBeAg). All children received hepatitis B immunoglobulin and complete HBV vaccination. Total RNAs from 82 adult non-tumor liver tissues were quantified for NTCP, type I interferons and interferon-induced transmembrane protein 3 (IFITM3) levels.

Results

A higher rate of the GA/AA genotype (28.3% vs. 15.3%, p = 0.006) of the genetic variant rs4646287 in intron 1 of the NTCP gene was detected in control children compared to the carrier children. The rs4646287 G > A genotype was associated with younger ages at which spontaneous HBeAg seroconversion occurred (10.8 ± 8.4 vs. 14.6 ± 8.7 years, p = 0.003) in chronic HBV-infected children. Unique correlation patterns of NTCP and innate immunity-related genes (type I interferons and IFITM3) were found in HBV-infected liver tissues with the rs4646287 G > A genotype.

Conclusion

The rs4646287 G > A genotype of the NTCP gene may be associated with lower risk for HBV vaccine failure in children born to highly infectious mothers. The protective effect of rs4646287 G > A was also present in carrier children, evidenced by earlier spontaneous HBeAg seroconversion."xsd:string
