Statin trial targets hidden heart risk in vasculitis patients

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Patient \> 18 years. ANCA-associated vasculitis: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss syndrome). Patients will fulfill the Chapel Hill Consensus Criteria and the American College of Rheumatology criteria, in remission of vasculitis. Patients in remission of vasculitis after induction therapy (for first flare or relapse), including corticosteroids associated or not with immunosuppressive agents according to Good Clinical Practice for the treatment of vasculitis, between 6 months and 10 years after the beginning of induction therapy. Patients with informed and signed consent Exclusion Criteria: Other systemic vasculitis. Secondary vasculitis (paraneoplastic or infectious).

Hypersensitivity to rosuvastatin or to any of the excipients. Pregnancy. Chronic HCV, HBV and/or HIV infection. Patient receiving other statin or other hypolipemic agent. Patient requiring treatment with statin according to Afssaps recommandations published in 2005 as primary or secondary prevention. Subclinical atherosclerosis that confers a high cardiovascular risk before patient randomization : * Carotid stenosis greater than 50% in diameter * Ectasia of the abdominal aorta * Intima-media thickening greater than 1.2 mm * Diffuse atherosclerosis lesions * Heterogeneous or hypoechoic prominent plaques greater than 2 mm Participation in another interventional study within 3 months before inclusion. Sick patients will not be excluded if they participate simultaneously in a strictlu observational study or a study with only blood samplings. Any medical or psycatric disease that could prevent from administrating drugs or from following-up the patient according to the protocol, and/or that would expose the patient to an important number of side effects, according to the principal investigator.
