Insights
HIV infection and antiretroviral therapy (ART) can alter lipid profiles. This study found reduced cardiovascular risk in HIV patients over nine months, mainly due to increased HDL cholesterol.
Area of Science:
- Biochemistry
- Metabolic Medicine
- Cardiovascular Health
Background:
- HIV infection and antiretroviral therapy (ART) are known to influence biochemical and metabolic parameters, including lipid profiles.
- Dyslipidemia is common in individuals with HIV, impacting their cardiovascular health.
- Understanding lipid profile changes is crucial for managing long-term health outcomes in HIV patients.
Purpose of the Study:
- To compare changes in lipid profiles among HIV-positive outpatients over a nine-month period.
- To assess the impact of HIV infection and ART on lipid parameters and cardiovascular risk.
- To investigate trends in total cholesterol (TC), HDL cholesterol, and TC/HDL ratio.
Main Methods:
- A nine-month observational study involving 171 HIV-positive outpatients.
- Patients were categorized as ART-naïve or ART-experienced, with classification based on intent-to-treat.
- Lipid profiles (TC, HDL) were measured at baseline and follow-up.
Main Results:
- Over 60% of patients exhibited dyslipidemia at baseline or follow-up, though mean lipid values remained within normal limits.
- ART-experienced patients had slightly higher mean TC and HDL levels at baseline and follow-up.
- A notable increase in HDL was observed in ART-naïve patients compared to ART-positive patients, leading to a decreased TC/HDL ratio in both groups.
Conclusions:
- HIV-positive patients frequently experience dyslipidemia, but average atherogenic lipid levels did not significantly change over nine months.
- The observed increase in HDL cholesterol suggests a potential reduction in cardiovascular disease (CHD) risk.
- Long-term monitoring of lipid profiles is essential for managing cardiovascular health in the context of HIV infection and ART.
Abstract:
HIV infection, together with ART, is associated with changes in biochemical, metabolic parameters and lipid profiles. The aim of this study was to compare changes in lipid profiles among HIV positive outpatients over nine months. 171 patients were investigated, 79% were ART experienced, and 82% of ART experienced patients were on NVP/EFV first line at baseline, but some patients changed ART groups over follow-up and classification was based on intent to treat. More than 60% ART naïve and ART experienced patients had some form of dyslipidemia either at baseline or at follow-up, but mean lipid values for the two groups were within normal limits. At baseline and follow-up, mean levels of TC and HDL were slightly higher in the ART experienced group. Interestingly, there was higher increase in HDL over time in the ART negative group compared to the ART positive group. There was a decrease in TC/HDL ratio in both groups over time, suggesting a reduction in calculated risk of CHD over time. HIV positive patients frequently show various forms of dyslipidemia, but there are no changes in average atherogenic lipid levels and results suggest reduced risk of CHD, mainly due to increases in HDL, after nine months of observation time.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
