Insights
Children with vertically transmitted HIV infection show impaired executive functioning, including attention and memory deficits. These cognitive impairments are linked to the severity and duration of HIV neuroinfection before treatment.
Area of Science:
- Neuroscience
- Pediatrics
- Infectious Diseases
Background:
- Vertically transmitted HIV infection can impact neurodevelopment.
- Cognitive function in children with HIV requires thorough assessment.
Purpose of the Study:
- To evaluate cognitive impairments in children and adolescents with vertically transmitted HIV.
- To explore associations between cognitive deficits and clinical/socio-demographic factors.
Main Methods:
- Compared cognitive performance of 50 HIV-infected children (PHIV+) with 24 HIV-exposed uninfected (PHEU) and 43 healthy controls (HIV-nA).
- Utilized the CANTAB Research Suite for cognitive assessments.
- Analyzed data considering age groups and viral load at treatment initiation.
Main Results:
- PHIV+ group demonstrated poorer performance in movement execution, attention shifting/flexibility, reversal learning, and working memory compared to HIV-nA.
- PHIV+ group showed increased planning time in memory tasks versus PHEU group.
- Adolescents (12-18 years) with HIV exhibited widespread cognitive deterioration.
- Higher baseline viral load correlated with worse outcomes in feedback use, attention, flexibility, and information processing.
Conclusions:
- Children with vertically transmitted HIV exhibit significant executive functioning deficits.
- Cognitive impairments are associated with prolonged HIV neuroinfection and infection severity prior to treatment.
Objectives:
The aim of the study was to assess the presence of cognitive impairments in children and adolescents with vertically transmitted HIV infection and to determine possible relationships with clinical and socio-demographic variables.
Methods:
Fifty children with perinatal HIV infection aged 6-18 years were included in the experimental group (PHIV+). Two sex- and age-matched groups were recruited as reference groups: (1) a PHEU group that included 24 healthy children perinatally HIV-exposed but uninfected, and (2) an HIV-nA group that included 43 healthy children of uninfected parents. CANTAB Research Suite was used to assess cognitive functioning.
Results:
In comparison with the HIV-nA group, the PHIV+ group scored worse in movement execution, shifting and flexibility of attention, reversal learning and working memory. In comparison with the PHEU group, the PHIV+ group had significantly longer planning time in the memory task. The analysis of results for the 12-18 year-old age group revealed deterioration of cognitive functions in all tests of the PHIV+ children in comparison with the HIV-nA group. A higher logarithm of viral load at the start of the ARV treatment was associated with worse results in the use of feedback, shifting of attention, cognitive flexibility and worse information processing.
Conclusions:
Results of the research indicate deterioration of executive functioning in the PHIV+ group associated with longer duration of HIV neuroinfection and severity of infection before treatment.
