Abstract: Objective To investigate the efficacy and safety of tenofovir alafenamide fumarate (TAF)
on the prevention of mother-to-child transmission of hepatitis B virus (HBV). Methods CNKI,
VIP, WanFang Data, PubMed, ScienceDirect, The Cochrane Library and EMbase databases were
electronically searched to collect studies of TAF used in pregnant women from inception to February
2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias
of included studies. Meta-analysis was then performed by using RevMan 5.4 software. Results A
total of 6 studies involving 596 patients were included. The results of Meta-analysis showed that
TAF and tenofovir disoproxil fumarate (TDF) may have similar effects on preventing mother-to-
child transmission of HBV (RR = 0.67, 95%CI: 0.12～3.75, P = 0.65), the incidence of congenital
malformations (RR = 0.33, 95%CI: 0.01～7.91, P = 0.50) and maternal prenatal HBV DNA level
(SMD = 0.09, 95%CI: -0.09～0.26, P = 0.34). No serious adverse reactions occurred in TAF group.
The effect of TAF on creatinine (SMD = -0.90, 95%CI: -3.22～1.42, P = 0.45) was similar to that
of TDF, however, the effect on urine β2 glycoprotein was smaller than that of TDF. Conclusions
Current evidence showed that TAF and TDF might have similar effects on preventing mother-tochild transmission of HBV, and TAF had less effect on renal function than TDF. It is suggested
that TAF might be more suitable for pregnant woman with HBV infection complicated with renal
function impairment than TDF.
