Abstract
Treatment for HIV infection in the past 3 years has significantly improved the prognosis of people infected with HIV. Protease inhibitors have played a critical role in this improved prognosis. Recent findings indicate, however, that protease inhibitors may cause significant alterations in lipid metabolism. This study reviewed the incidence of lipid abnormalities associated with the use of three different protease inhibitor therapies and identified that 56% of those who were assessed had abnormal elevated lipids. Following initiation of the protease inhibitor, a significant increase in cholesterol was found in 80% of the patients on norvir/saquinavir, 51% of patients on indinavir, and 47% of patients on nelfinavir. These lipid alterations have added a new and unexpected health risk for HIVinfected persons. The risks of therapy with protease inhibitors may have a greater life-threatening potential than the disease itself. This article will review the published findings suggestive of protease inhibitor hyperlipidemia and will highlight the findings of these events in a clinical setting. The purpose of this article is to alert the nursing community of this potential serious side effect and to make recommendations that may be put into practice so that complications may be reduced.
