About
Treatment with HIV-infection with protease inhibitors is associated with high blood lipids and higher chance for cardiovascular complications. The RASSTER study aims to investigate the effect of switching the protease inhibitor lopinavir/ritonavir to raltegravir on vessel wall function and inflammation,and activation of the immune system. we hypothesize that with this intervention these parameters will improve. Since decreased vessel wall function and inflammation are initial steps in the process of atherosclerosis, it is important to know this data when treating HIV-infected patients.
Full description
Fixed dose combination lopinavir/ritonavir (LPV/r) is a widespread used antiretroviral drug belonging to the class of protease inhibitors (PIs). PIs are associated with an increased risk of myocardial infarction. However, data is available suggesting increased levels of plasma lipids are not the sole explanation for this observation. Treatment with LPV/r might lead to a decrease of endothelial function as well, thus explaining the increased risk of myocardial infarction besides increased plasma lipids. Raltegravir is a registered antiretroviral drug with no known cardiovascular side effects. We hypothesize that switching LPV/r to raltegravir in HIV-infected patients with suppressed plasma viral load (<50 copies/ml) will lead to an improvement of endothelial function.
