Study Summary
This study will examine how the anti-HIV protease inhibitor lopinavir/ritonavir (Kaletra® (Registered Trademark)) affects the function of the endothelium (lining of the arteries). Medications such as protease inhibitors can dramatically change the course of HIV infection in many patients; however, among their side effects is development of abnormal lipid levels resulting in high cholesterol and insulin resistance. These side effects may damage the lining of the arteries that supply blood to the heart, leading to premature coronary artery disease. The study will determine whether lopinavir/ritonavir directly affects endothelial function and whether it alters cholesterol levels, glucose tolerance, and markers of inflammation in people who take the drug for 4 weeks. Healthy normal volunteers between 18 and 40 years of age may be eligible for this study. Candidates must be HIV-negative and have no history of heart disease, hypertension, or diabetes mellitus. They must not have smoked for at least 6 weeks before entering the study. Volunteers will be screened with a medical history, physical examination, blood tests (including a pregnancy test for women of childbearing potential), and electrocardiogram. In addition, candidates will have an oral glucose tolerance test (see description below). Participants will undergo the following procedures: * Lopinavir/ritonavir: 4 weeks (3 capsules twice a day) beginning study day 1 * Flow-mediated vasodilatation test (study days 0 and 29) - An ultrasound device for measuring the size of the brachial artery (artery in the upper arm) is placed just above the elbow. The size of the artery is measured before and 5 minutes after blood flow to the arm is stopped for 5 minutes, using a blood pressure cuff. The artery is also measured before and after taking nitroglycerin, a medicine that dilates blood vessels. These measurements tell how well the drug treatment works on the cells lining the brachial artery, which is an indicator of coron
