New US advice on dysregulated lipids

This article is more than 24 years old.

A heart disease focus group set up by the US AIDS Clinical Trials Group (ACTG) has released preliminary guidance on the management of abnormal blood lipid levels in people taking antiretroviral therapy. A complete version of their recommendations is in press with Clinical Infectious Diseases and will appear in the summer.

The statement notes that whilst the association between HIV treatment and lipid abnormalities has been established for some time, whether this equates with a significant risk of heart disease remains unclear. Nevertheless, the focus group recommends that dysregulated lipids in people with HIV should be managed according to existing (US) advice for the care of the general population, namely the National Cholesterol Education Program guidelines. (Note that advice outside the US may differ).

However, the potential for negative drug interactions between standard lipid-lowering agents and antiretroviral drugs raises specific concerns for people with HIV. The use of non-drug therapies, e.g. dietary modifications, exercise, is therefore emphasised as a potentially more appropriate choice in many cases, particularly where the risk of heart disease is low, (such as in people who have no family history of heart disease, or no other risk factors).

Glossary

lipid

Fat or fat-like substances found in the blood and body tissues. Lipids serve as building blocks for cells and as a source of energy for the body. Cholesterol and triglycerides are types of lipids.

focus group

A group of individuals selected and assembled by researchers to discuss and comment on a topic, based on their personal experience. A researcher asks questions and facilitates interaction between the participants.

metabolism

The physical and chemical reactions that produce energy for the body. Metabolism also refers to the breakdown of drugs or other substances within the body, which may occur during digestion or elimination.

cholesterol

A waxy substance, mostly made by the body and used to produce steroid hormones. High levels can be associated with atherosclerosis. There are two main types of cholesterol: low-density lipoprotein (LDL) or ‘bad’ cholesterol (which may put people at risk for heart disease and other serious conditions), and high-density lipoprotein (HDL) or ‘good’ cholesterol (which helps get rid of LDL).
