Clinical Care and Management (CCM)
Thanks to advances in treatment, many women living with HIV can get pregnant with minimal risk of giving birth to a child who has the virus. While most children who are HIV-exposed but uninfected (CHEU) are in good health, it is unclear how exposure to HIV and antiretroviral therapy (ART) during pregnancy could impact their brain development and long-term health.
CTN 315 aims to examine brain development and long-term behavioural and cognitive function of CHEU by comparing brain structure and function between CHEU and children who are HIV-unexposed and uninfected (CHUU). The study hopes to address clinically important knowledge gaps that affect the long-term health of CHEU.
In Canada, 200-300 babies are born to women living with HIV each year, and almost all of these children are HIV-negative despite exposure to the virus, thanks to ART and transmission prevention programs. A number of observational studies suggest that HEU children may have a higher risk of health issues such as increased morbidity and mortality in the first year of life, higher likelihood of pre-term birth, increased risk of infection, and mental health impairments. The increasing number of CHEU could result in more instances of health issues, impacting on public health and the CHEU’s ability to reach their full potential.
This multi-site prospective clinical study will conduct cognitive, behavioural, and brain imaging (MRI and MR spectroscopy) investigations of 180 CHEU and 65 CHUU to better characterize overall brain function and explore links between brain function and behavioural deficits and changes in specific brain regions.
