Costs and benefits of multidrug, multidose antiretroviral therapy for prevention of mother-to-child transmission of HIV in the Dominican Republic.

OBJECTIVE: To investigate whether costs of multidose antiretroviral regimens (MD-ARVs), including highly active antiretroviral therapy (HAART), for prevention of mother-to-child transmission (PMTCT) of HIV might be offset by savings gained from treating fewer perinatally acquired infections. METHODS: Rates of MTCT reported in the Dominican Republic among mother-infant pairs treated with single-dose nevirapine (SD-NVP; n=39) and MD-ARVs (n=91) for PMTCT were compared. Annual births to women infected with HIV were estimated from seroprevalence studies. Antiretroviral costs for both PMTCT and for HAART during the first 2 years of life (in cases of perinatal infection) were based on 2008 low-income country price estimates. RESULTS: Rates of MTCT were 3.3% and 15.4% for the MD-ARV and SD-NVP groups, respectively (P=0.02). Assuming that 5775 of 231 000 annual births (2.5%) were to HIV-positive women, it was estimated that 191 perinatally acquired infections would occur using MD-ARVs and 889 using SD-NVP. High costs of maternal MD-ARVs (HAART, US$914,760 versus SD-NVP, $1155) would be offset by lower 2-year HAART costs ($250,344 versus $1,168,272 for infants in the SD-NVP group) for the lower number of children with prenatally acquired infection (191 versus 889) associated with the use of MD-ARVs for PMTCT (net national saving $3168). CONCLUSION: Despite the high costs, use of MD-ARVs, such as HAART, for PMTCT offer societal savings because fewer perinatally acquired infections are anticipated to require treatment.

Immune reconstitution inflammatory syndrome due to Mycobacterium bovis Bacillus Calmette-Guerin in infants receiving highly active antiretroviral therapy: a call for universal perinatal rapid HIV testing prior to administration of BCG immunization of neonates.

The evidence behind the World Health Organization guidelines that BCG vaccination should not be used in HIV-infected children is compelling. We report three cases of severe BCG-associated immune reconstitution syndrome in HIV-infected infants and describe measures available in developing countries that prevent inadvertent BCG immunization in these infants.
