BACKGROUND : Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) has become an essential global health issue and its elimination is a crucial target. A prenatal "opt-out" HIV screening program was initiated in 2005 in Taiwan. In recent 3 years, approximate screening and MTCT rates were 99% and 2.27% (1/44), respectively. Here, we describe the clinical management of mothers infected with HIV and MTCT rate at National Taiwan University Hospital (NTUH), Taipei, Taiwan, in the years after the program was initiated.
METHODS : We retrospectively reviewed charts of pregnant women infected with HIV, who were managed at NTUH between January 2005 and December 2016. HIV infection status of 39 infants born to mothers infected with HIV was available.
RESULTS : Between 2005 and December 2016, 50 pregnant women infected with HIV, with 57 parities were managed at NTUH, and 57 live infants were born. We excluded 18 parities because of missing data. Maternal antiviral treatment was administered in 37 of 39 infants. Only one infant tested positive for an HIV antibody test at 18 months, but showed definitive HIV exclusion at 20 months after a series of tests without administration of antiviral treatment. MTCT rate was 0%.
CONCLUSIONS : Successful implementation of available perinatal HIV intervention dramatically reduced vertical transmission rate of HIV. MTCT rate was 0% in NTUH after the program. However, as NTUH is an HIV referral center, additional efforts are needed to achieve the World Health Organization criteria of lowering the vertical transmission rate of HIV to <2% in Taiwan.
