|Elevated Cholesterol and Triglycerides
Feb 6, 2002
Medical history: I have been HIV positive for over 20 years and am a healthy and active 39 year-old man. I see a nutritionist in addition to a medical doctor and have always tried to choose the least toxic route in my treatment plan--including extensive vitamin therapy. For years I only had 11 t-cells and had trained myself not to focus on numbers as a sole gauge of health. I am a competitive athlete and excercise rigorusly between 2 and 4 times a week, so I can eastily tell when my body is not feeling right. A brief bout of pmneumonia in 96 resulted in the commencement of Crixivan, D4t, and 3TC 6 years ago. After 18 months, I switched to Viracept and kept all other meds the same. In reviewing my blood tests, my CD4 increased and have been between 450 and 550 for thepast 4 years and although my viral load became undetectable, it is currently hovering between 1500 and 2000. The current issue at hand is my cholesteral and triglyceride levels. The triglycerides have continuously increased from 250 in June '99 to a current level of 1280. My cholestrol has been steady at 250.
First off, what do you advise as the least toxic way to reduce the triglycerides and cholesterol? And secondly, what level is too much?

To assess the cholestserol you might need to have the sample centrifuged and then measure the LDL component and the HDL component. Often with high triglycerides the VLDL component is high but the LDL (the worst form) isn't too bad. The HDL (the good cholesterol) is often somewhat low. After a careful fasted specimen then a plan can be developed. LDL levels > 100 are a concern (esp if > 130). Triglyceride levels > 250-300 are of more modest concern. Sometimes switching off the PI to something like Trizivir (AZT + 3TC + abacavir) + nevirapine might drop the lipids noticeably. An upcoming ACTG study uses the long acting form of niacin for elevated non-HDL cholesterol levels. For mostly triglyceride elevations fenofibrate or gemfibrozil can help some. Additional benefit can be seen with a statin such as pravastatin or atorvastatin but monitoring for muscle damage (rare but it happens) needs to be done. Small amounts of alcohol can increase the HDL but might make the risk for pancreatitis go up (a risk due to the high triglycerides). Exercise is good. A cardiac aspirin a day is recommended. KH
