Summary
Human immunodeficiency virus (HIV) infection in infants can cause microcephaly and myelination delay. Early-onset leukoencephalopathy is associated with these brain changes in young children.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neuroscience
Background:
- Microcephaly, characterized by a significant brain weight deficit, is a concern in infants.
- Vertical transmission of human immunodeficiency virus (HIV) poses risks to infant neurodevelopment.
Purpose of the Study:
- To investigate white matter changes in infants with microcephaly due to vertical HIV infection.
- To identify the correlation between HIV infection and specific neuropathological findings.
Main Methods:
- Examination of brain tissue from six infants (14-34 months) with microcephaly and vertical HIV infection.
- Histopathological analysis focused on white matter lesions, myelin pallor, gliosis, and myelination status.
Main Results:
- HIV-1 infection-related leukoencephalopathy, marked by myelin pallor and gliosis, was observed in the periventricular white matter of four infants.
- Myelination delay was noted in all affected infants.
- One case presented with diagnosed HIV encephalitis.
Conclusions:
- HIV-infected infants with microcephaly often exhibit myelination delay and early-onset leukoencephalopathy.
- These findings suggest a correlation between HIV infection and reduced brain growth in infants.
- Further research is needed due to the preliminary nature of these findings from a small cohort.
