Clinical Scorecard: Emerging Perspectives on Perinatal HIV: Advancing Research Towards an HIV Cure
At a Glance
Category
Detail
Condition
Perinatal HIV infection
Key Mechanisms
Persistence of intact HIV proviruses in long-lived cellular reservoirs despite ART; timing of ART initiation influences reservoir size and decay
Target Population
Children and adolescents with perinatal HIV infection
Care Setting
Pediatric HIV care and research settings focusing on ART and HIV cure strategies
Key Highlights
Early initiation of ART (by 1 year of age) in children with perinatal HIV leads to significantly lower levels of intact proviral DNA compared to later ART initiation.
Intact HIV proviral DNA declines biphasically during ART, with an initial rapid decline followed by a slower decay or stabilization, influenced by proviral integration sites and clonal proliferation.
Smaller HIV reservoirs in early treated children correlate with longer times to viral rebound and potential for ART-free remission, supporting early ART as a critical component of cure strategies.
Guideline-Based Recommendations
Diagnosis
Use multiplex PCR assays to differentiate intact from defective HIV proviruses for accurate reservoir assessment.
Management
Initiate ART as early as possible in infants with perinatal HIV to reduce intact proviral reservoir size.
Consider adjunctive interventions targeting reservoir reduction ('surge and purge') alongside ART to advance towards HIV remission or cure.
Monitoring & Follow-up
Monitor intact proviral DNA levels longitudinally to assess reservoir dynamics and treatment efficacy.
Evaluate immune responses, including Natural Killer cell activity, which may influence reservoir decay.
Risks
Challenges in obtaining sufficient cell numbers from infants for reservoir quantification may limit assessment accuracy.
Late ART initiation is associated with larger intact proviral reservoirs and higher risk of viral rebound upon ART cessation.
Patient & Prescribing Data
Children and adolescents with perinatal HIV infection
Early suppressive ART initiation correlates with lower intact proviral DNA levels and improved prospects for ART-free remission; late ART initiation results in higher reservoir levels and reduced likelihood of remission.
Clinical Best Practices
Prioritize early diagnosis and prompt initiation of ART in infants with perinatal HIV infection.
Utilize advanced assays capable of distinguishing intact from defective proviruses to guide clinical decisions.
Incorporate immune monitoring to understand host factors affecting reservoir dynamics.
Develop and apply reservoir-targeting interventions in conjunction with ART to facilitate HIV remission or cure.
Recognize limitations in sample size and cell availability in pediatric populations and adapt protocols accordingly.
A retrospective cohort study of more than 520,000 hospitalized patients found no clinically meaningful improvement in deterioration or mortality with early treatment targeting community-acquired pneumonia.
