| Although mother-to-child HIV transmission prevention has slowed down pediatric HIV infection in developed countries, large numbers of infants still become infected in developing nations. Data on pediatric HIV infection is however largely scarce. In this study, we have overviewed clinical, laboratory and genotypic data from a large cohort of HIV-infected infants regularly followed at two pediatric HIV outpatient clinics in Rio de Janeiro, Brazil. Children on antiretroviral therapy, as well as drug-naïve, newly diagnosed infants were analyzed. Prevalence of drug resistance mutations, as well as immunological and virological responses to therapy were evaluated. Additionally, HIV-1 subtype frequencies and their distribution over the course of the epidemic were... |

| OBJECTIVES: To determine the HIV vertical transmission rate (VTR) and associated risk factors by use of zidovudine and infant care education in Brazil. METHODS: Since 1995, a prospective cohort of HIV infected pregnant women has been followed at the Federal University of Rio de Janeiro. A multidisciplinary team was established to implement the best available strategy to prevent maternal-infant HIV transmission. Patients with AIDS or low CD4 and high viral load received anti-retroviral drugs in addition to zidovudine. Children were considered infected if they had 2 positive PCR-RNA tests between 1 and 4 months of age, or were HIV antibody positive after 18 months. Education regarding infant treatment and use of formula instead of breast feeding was... |

| This report describes a case of Toxoplasma encephalitis during pregnancy of an HIV infected woman who was severely immunosuppressed (CD4: 17 cells/mm3), had a high viral load (RNA PCR:230,000 copies/ml), was treated with sulfadiazine, pyrimethamine and folinic acid for toxoplasmosis and was being treated with highly potent antiretroviral drugs (AZT, 3TC and nelfinavir) for HIV infection. The newborn was born through an elective C-section, received six weeks of AZT according to the 076 protocol and was clinically normal at birth. Subsequently he had two RNA PCR negatives for HIV, seroreverted and had no clinical or laboratory evidence of congenital toxoplasmosis. Despite the concerns of the use of these combined therapies on the foetus during pregnancy,... |
