RESUMO
OBJECTIVE: To ascertain the effect of rosuvastatin on carotid atherosclerosis and arterial stiffness in patients with rheumatoid arthritis (RA). METHODS: Fifty RA patients were randomized in a double-blind placebo-controlled trial to receive 10 mg rosuvastatin (n = 24) or placebo (n = 26). Patients were followed prospectively every 3 months for 12 months. Intima-media thickness (IMT), augmentation index (AIx), and subendocardial viability ratio (SEVR) were measured at baseline, 6 and 12 months. RESULTS: Rosuvastatin resulted in statistically significant reductions of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), apolipoprotein B (Apo B), and urate levels vs. placebo. However, rosuvastatin had no significant effect on changes in inflammatory markers, including C-reactive protein (CRP) levels [from 2.9 (1.4-11.0) to 3.1 (0.9-13.3) mg/L in the rosuvastatin group compared with from 5.8 (2.6-14.2) to 4.4 (1.2-12.3) mg/L in the placebo group]. Nonetheless, a significant improvement in the Disease Activity Score (DAS) and a reduction in fibrinogen level was observed at 6 and 12 months compared with baseline in the rosuvastatin group. The treatment group exhibited a significant increase in SEVR (from 157 ± 28% to 163 ± 33% in the rosuvastatin group compared with from 143 ± 18% to 143 ± 26% in the placebo group, p = 0.023), but no significant effect was observed in the changes in IMT and AIx. CONCLUSION: Our data suggest that rosuvastatin has a modest anti-inflammatory effect in RA patients with low disease activity in terms of reduction in DAS and fibrinogen level. Rosuvastastin may also improve subendocardial perfusion and lower the urate level.
