Cognitive and motor development in children with vertically transmitted HIV infection

Area of Science:

• Pediatrics
• Neurodevelopmental Disorders
• Infectious Diseases

Background:

• Vertical transmission of human immunodeficiency virus (HIV) can impact infant development.
• Early neurodevelopmental outcomes in vertically HIV-infected infants require thorough examination.
• Understanding developmental trajectories is crucial for timely intervention.

Purpose of the Study:

• To investigate mental and motor development in infants with vertically transmitted HIV infection.
• To compare neurodevelopmental outcomes between HIV-infected and uninfected infants born to HIV-positive mothers.
• To identify factors associated with developmental impairments in this cohort.

Main Methods:

• Neurodevelopmental assessment using the Bayley Scales of Infant Development (BSID).
• Comparison of mental development index (MDI) and psychomotor development index (PDI) scores between HIV-infected and uninfected infants.
• Correlation analysis between neuroimaging findings (CT scans) and developmental outcomes in HIV-infected children.

Main Results:

• HIV-infected infants demonstrated significantly lower MDI and PDI scores compared to uninfected controls.
• Abnormalities on CT scans were observed in 20 HIV-infected children.
• CT scan abnormalities, particularly subcortical lesions and myelination issues, were associated with developmental delays, especially in motor function.

Conclusions:

• Vertically transmitted HIV infection is associated with significant impairments in early mental and motor development.
• Early neuroimaging findings, such as myelination abnormalities and subcortical lesions, are linked to developmental delays.
• These findings underscore the need for early and comprehensive neurodevelopmental monitoring and support for vertically HIV-infected infants.
