MedicalResearch.com Interview with: Marcin Jankiewicz  University of Cape Town Cape Town, South Africa  MedicalResearch.com: What is the background for this study? Response: The Children with HIV Early Antiretroviral (CHER) trial, conducted in Cape Town and Soweto, was designed when there was uncertainty whether to start antiretroviral therapy (ART) as soon as HIV was diagnosed (below 12 weeks of age) or to wait until there was evidence of immuno-compromise and disease progression. Also, there were concerns about maintaining adherence, long-term toxicity and also resistance in the setting of few antiretroviral options. Early outcomes showed a decreased risk in childhood mortality in the early treatment arms compared to deferred treatment, becoming standard of care globally. The CHER cohort is one of the largest and best documented of children receiving ART within the first year of life. Also, age- and community-matched HIV exposed uninfected (HEU) and HIV unexposed (HU) uninfected infants were enrolled in parallel for a linked vaccine study. We therefore had an amazing opportunity to link with a neurodevelopmental sub-study in participants from Cape Town and apply sophisticated neuroimaging modalities that could link with clinical, virological and immunological characteristics.
