TABLE 2.
Summary of the Clinical Management Concerns When Treating HIV-Infected Children
Area | Management Issues Requiring Research |
---|---|
Neurocognitive development | Children with HIV accelerate their neurologic development after starting HAART, but they do not catch up with other children |
Neurocognitive development in HIV-exposed but uninfected children is also below normal and needs further study | |
The socioeconomic and medical reasons for residual developmental delay in HAART-treated children remains to be delineated | |
Bone growth | HAART in general, as well as specific antiretroviral agents, has been associated with subnormal bone mineral content |
Children may be especially vulnerable to these effects | |
A major confounding factor is the worldwide deficiencies in calcium and vitamin D | |
Metabolic abnormalities | HAART initiation is associated with decreases in inflammatory cytokines |
Children on HAART nevertheless experience high rates of fat wasting, insulin resistance, dyslipidaemia and hyperlactataemia | |
High cholesterol levels may lead to cardiovascular disease, but aggressive lipid management is lacking in children | |
HIV/TB coinfection | Concurrent HAART improves the response to TB therapy, but TB therapy can have negative effects on HAART effectiveness and toxicity |
Drug-drug interactions and overlapping toxicities pose challenges to concurrent treatment of HIV and TB | |
Pharmacokinetic data on the drug-drug interactions are sparse in children | |
Data on management of TB and malnutrition, extrapulmonary disease, drug resistance and IRIS in children are very limited | |
HIV/Malaria coinfection | HIV’s effect on childhood malaria is unclear |
There is only limited paediatric data on PK and toxicity interactions between antiretroviral and antimalarial agents | |
Some HAART components may be active against malaria, but this requires further study | |
Malnutrition | Malnutrition may interfere with absorption of HAART drugs |
Malnourished children have relatively poor outcomes after initiating HAART, but there are no long-term data in this area | |
Researchers have not developed optimal antiretroviral/nutritional strategies for malnourished children |
