Low maternal plasma viral load is the key factor for preventing MTCT. Benefits in terms of MTCT reduction may be expected from early antiretroviral prophylaxis. The potential toxicity of prolonged antiretroviral use in pregnancy should be evaluated.
Children exposed to nucleoside analogues during the perinatal period are at risk of a neurological syndrome associated with persistent mitochondrial dysfunction.
The prematurity rate among HIV-infected pregnant women was twice that in the general population in France; this was not entirely explained by sociodemographic characteristics. Prematurity was independently associated with cARV therapy and, particularly, with the initiation of ritonavir-boosted PI therapy during pregnancy.
Puberty seems to be the time when HIV-infected children taking potent antiretroviral therapy are more likely to develop lipodystrophy and metabolic complications, especially in children with a severe underlying HIV infection. Once developed, lipodystrophy and metabolic changes seem to be extremely stable with time.
BACKGROUND. Increasing numbers of children perinatally infected with human immunodeficiency virus (HIV) are reaching adolescence, largely because of advances in treatment over the past 10 years, but little is known about their current health status. We describe here the living conditions and clinical and immunovirologic outcomes at last evaluation among this pioneering generation of adolescents who were born before the introduction of prophylaxis for vertical transmission and whose infections were diagnosed at a time when treatment options were limited. METHODS. The eligible population consisted of HIV-1-infected children who were born before December 1993 and who were included at birth in the prospective national French Perinatal Cohort (EPF/ANRS CO10). RESULTS. Of the 348 eligible children, 210 (60%; median age, 15 years) were still alive and regularly followed up. Current treatment was highly active antiretroviral therapy (HAART) in 77% and 2 nucleoside analogues in 5.0%; 16% had stopped treatment, and 2% had never been treated. The median CD4 cell count was 557 cells/microL, and 200 cells/microL was exceeded in 94% of patients. The median viral load was 200 copies/mL. Viral load was undetectable in 43% of the adolescents and in 54.5% of those receiving HAART. Median height, weight, and body mass index were similar to French reference values for age, and school achievement was similar to nationwide statistics. Better immunologic status was associated with being younger and with having begun HAART earlier. Undetectable viral load was associated with maternal geographic origin and current HAART. CONCLUSIONS. Given the limited therapeutic options available during the early years of these patients' lives and the challenge presented by treatment adherence during adolescence, the long-term outcomes among this population are encouraging.
Early and sustained control of viral load is associated with a decreasing residual risk of MTCT of HIV-1. Guidelines should take into account not only CD4(+) T cell count and risk of preterm delivery, but also baseline HIV-1 load for deciding when to start antiretroviral therapy during pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
