Insights
Lipid abnormalities in children with HIV and lipodystrophy remained stable over 30 months. Adiponectin levels did not effectively indicate lipodystrophy in this HIV-infected pediatric cohort.
Area of Science:
- Pediatric Endocrinology
- Infectious Diseases
- Metabolic Disorders
Background:
- HIV-associated lipodystrophy (LD) presents with fat maldistribution, dyslipidemia, and insulin resistance in children on antiretroviral therapy.
- Understanding the long-term stability of these metabolic abnormalities is crucial for patient management.
Purpose of the Study:
- To evaluate the stability of lipid abnormalities in children with HIV over a 30-month period.
- To investigate potential biomarkers for lipodystrophy in this population.
Main Methods:
- Prospective, observational study of a perinatally HIV-infected cohort.
- Five study visits over 30 months, collecting blood for HIV-1 RNA, CD4 counts, lipid profiles, glucose, insulin, adiponectin, and IGF-I/IGFBP-3.
- Analysis compared lipid levels between patients on protease inhibitors (PIs) versus non-PIs, and between those with and without lipodystrophy (LD).
Main Results:
- Patients on PIs had significantly higher LDL-cholesterol, total cholesterol (TC), triglycerides (TG), and free fatty acids (FFA).
- Patients with LD exhibited higher TC, TG, and FFA levels.
- HDL-cholesterol showed a decreasing trend, while FFA increased over time; adiponectin levels did not differ significantly between groups.
Conclusions:
- Dyslipidemia in children with HIV remained relatively stable throughout the 30-month study period.
- Adiponectin was not identified as a reliable marker for lipodystrophy in this pediatric cohort.
Background:
HIV-associated lipodystrophy (LD) manifests with fat maldistribution, dyslipidemia, and insulin resistance in some HIV-infected children on antiretroviral therapy.
Aim:
To assess whether lipid abnormalities in patients with HIV are stable over time.
Patients:
The perinatally HIV-infected cohort at a medium-sized urban US teaching hospital.
Methods:
This prospective, observational study consisted of five visits (at entry and 3, 6, 24, and 30 months after entry) during which fasting venous blood samples were drawn for HIV-1 RNA, CD4 lymphocytes, lipid profile, free fatty acids (FFA), glucose, insulin, and adiponectin. IGF-I/IGFBP-3 levels were measured at the first and fifth visits.
Results:
Of 36 study participants, seven were lipodystrophic, and 30 patients completed all five study visits. LDL-cholesterol, total cholesterol (TC), triglycerides (TG), and FFA levels were significantly higher in patients taking protease inhibitors (PIs). Patients with LD had higher TC and TG levels (both p < 0.05), and higher FFA (p = 0.0532). Adiponectin levels did not differ between PI/non-PI and LD/non-LD groups. HDL-cholesterol seemed to decrease, and FFA to increase over time. All IGF-I and all but one IGFBP-3 level were within normal range for age and Tanner stage.
Conclusion:
Dyslipidemia remained relatively constant over our study period. Adiponectin was not useful as a marker of LD in our population.
