Abstract
BACKGROUND Patients with systemic lupus erythematosus (SLE) have accelerated atherosclerosis that can be assessed by the carotid intima media thickness (CIMT) measurement. A prompt hypolipidemic treatment should be a part of the integral management. The aim of this study is to determine the effect of therapy with pravastatin plus ezetimibe on the CIMT in SLE patients. METHODS Longitudinal, prospective, quasi-experimental trial. Out of 60 SLE patients in whom a carotid ultrasound was performed, we chose 22 with a CIMT>0.7 mm who were administered pravastatin plus ezetimibe during 6 months with determination of CIMT at the end of the study. We performed the following tests: total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, tryglicerides, C-reactive protein (CRP), liver function, muscle enzimes and glucose, basal and at the end of treatment. STATISTICAL ANALYSIS descriptive statistics and Wilcoxon test were used. RESULTS There were 22 women with an age of 42±6.3 years, average disease evolution 7.5±6.6 years, of whom, 18 concluded the study. Right basal CIMT was 0.829±0.1448 vs. final 0.688±0.1453, p<0.003; left CIMT was 0.820±0.1312 vs. 0.724±0.1348, p<0.004. TC 208 mg/dl vs 168 mg/dl, LDL-C 125 mg/dl vs. 72 mg/dl, p=0.0004. CRP 3.12 vs. 2.25 p=0.004. In 2 cases there were gastrointestinal, skin and muscle adverse effects. CONCLUSIONS Treatment with pravastatin plus ezetimibe decreases the CIMT with improvement in the concentration of total cholesterol, LDL-C and CRP levels with good toleration.
