Tenofovir Disoproxil Fumarate for Prevention of Vertical Transmission of Hepatitis B Virus Infection by Highly Viremic Pregnant Women: A Case Series
Digestive Diseases and Sciences, 05/10/2012Pan CQ et al.
The preliminary data suggest that Tenofovir Disoproxil Fumarate (TDF) use in the third trimester is safe, and effectively prevents vertical transmission (VT) of hepatitis B virus (HBV) from high viremic HBeAg–positive mothers.
Data were collected retrospectively from HBV mono-infected, hepatitis B e antigen (HBeAg) positive, pregnant women between 6/2008 and 11/2010.
Cases enrolled were HBV mono-infected mothers who received TDF (300 mg orally once a day) in the third trimester.
Those with pregnancy complications or an abnormal fetus on sonography were excluded from use of TDF.
All infants received hepatitis B immunoglobulin and vaccination at birth and subsequently.
Eleven Asian mothers received TDF at the median gestational age of 29 (28-32) weeks and the median duration of TDF use before delivery was 10 (7-12) weeks.
A significant reduction in serum HBV-DNA was achieved at delivery compared with baseline (mean 5.25 ± 1.79 vs. 8.87 ± 0.45 log10 copies/mL, respectively; p < 0.01).
Three had serum ALT levels more than 1.5 times the upper limit of normal and two of these normalized before delivery.
The 11 infants were born with no obstetric complication or birth defects.
Five infants were breastfed.
All infants were hepatitis B surface antigen negative 28-36 weeks after birth.
