HDL-C may increase as much as 10% with rosuvastatin among those without HIV [29]. lipoprotein cholesterol (non-HDL-C) levels were reached, and toxicity rates. We used linear regression to examine change in lipid levels, controlling for baseline lipid values and demographic and clinical characteristics. We conducted secondary analyses using propensity scores to address confounding by indication. The most commonly prescribed statins were atorvastatin (= 303), pravastatin (= 280), and rosuvastatin (= 95). One year after starting a statin therapy, patients who received atorvastatin or rosuvastatin had significantly greater decreases in total cholesterol, LDL-C, and non-HDL-C than patients on pravastatin. The likelihood of reaching NCEP goals for LDL-C levels was higher with the use of rosuvastatin (OR 2.1; = .03) and atorvastatin (odds ratio [OR], 2.1; = .001) compared with that of pravastatin. The likelihood of reaching NCEP goals for non-HDL-C levels was higher for rosuvastatin (OR 2.3; = .045) but not atorvastatin (OR, 1.5; = .1) compared with pravastatin. Toxicity rates were similar for all those 3 statins: 7.3% for atorvastatin, 6.1% for pravastatin, and 5.3% for rosuvastatin. Our findings suggest that atorvastatin and rosuvastatin are preferable to pravastatin for treatment of HIV-infected patients with dyslipidemia, due to greater declines in total cholesterol, LDL-C, and non-HDL-C, with similar lower toxicity rates. Metabolic abnormalities such as dyslipidemia among human immunodeficiency virus (HIV)Cinfected patients result in significant morbidity, including increased cardiovascular disease risk [1]. Guidelines for managing dyslipidemia among HIV-infected individuals recommend statins (3-hydroxy-3-methylglutaryl coenzyme A [HMG CoA] reductase inhibitors) to treat elevated low density lipoprotein cholesterol (LDL-C) and nonChigh density lipoprotein cholesterol (non-HDL-C) levels above the thresholds set by the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) [2, 3]. Whereas statin use among HIV-infected individuals is increasing [4, 5], little is known about the comparative effectiveness and toxicity of these medications in routine care. Previous studies of statins and HIV infection have been limited by small sample size [6C13], short follow-up time or cross-sectional study design [13C15]. Most did not examine the effectiveness of different statins [6, 11], or were conducted before the availability of statins now in widespread use [6, 7, 13, 16]. Thus, questions remain regarding the comparative effectiveness of statins among HIV-infected individuals. We conducted this large, longitudinal study among a cohort of HIV-infected patients to compare the effectiveness and toxicity of statins in clinical care. This study is unique because of its large sample size; comparison of individual statins, including those more recently incorporated into clinical care; and systematic evaluation of reasons for discontinuing statin medications, including symptomatic toxicity. METHODS Study Setting This observational study was conducted among patients from the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort [17]. Isocorynoxeine Patients from 2 CNICS sitesthe University of Alabama at Birmingham and University of Washingtonwere included in this study. Study Participants HIV-infected individuals aged 18 years who started statins between 1 January 2000 and 1 March 2008 were eligible for the study. We included no data collected prior to 2000 because of concerns about changing practice patterns. Patients were followed up until statin discontinuation, switch to another statin, addition of another lipid-lowering agent, loss to follow-up, or 1 May 2008, whichever occurred first. Patients who started a statin while receiving other lipid-lowering agents were excluded. Change in statin dose was considered a continuation of the same regimen, as done previously [6]. Study procedures were approved by both the University of Washington and the University of Alabama at Birmingham institutional review boards. Source of Data The CNICS data repository integrates comprehensive clinical data from all outpatient and inpatient encounters, including demographic, clinical, laboratory, and medication data [17]. Reasons for stopping medications, including medication toxicity, are documented by the treating clinician in the electronic medical record at discontinuation or are captured by systematic review of all clinician progress notes recorded at the time of discontinuation. Lipid Outcomes and Other Key Variables We examined lipid levels over time, including levels of total cholesterol, LDL-C, high density lipoprotein cholesterol (HDL-C), triglycerides, and non-HDL-C (calculated by subtracting HDL-C from.Rosuvastatin appeared to be better than pravastatin for reaching individualized NCEP LDL-C and non-HDL-C goals. Toxicity Adverse events associated with statins among individuals without HIV infection are uncommon [31]. (= 280), and rosuvastatin (= 95).
