Atorvastatin decreases high-sensitivity C-reactive protein in multiple sclerosis.

The anti-inflammatory potential of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, as reflected by modulation of C-reactive protein (CRP), might be beneficial in the treatment of patients with multiple sclerosis (MS). We evaluated serum levels of high-sensitivity (hs)-CRP in relapsing-remitting MS patients receiving interferon-beta 1b and atorvastatin as add-on therapy. This study shows that interferon-beta treatment is associated with increased serum levels of hs-CRP in MS patients (P<0.01). In contrast, when atorvastatin is added to interferon-beta, hs-CRP serum levels decrease to the normal range (P<0.05), indicating an anti-inflammatory action of atorvastatin in MS. However, whether add-on treatment with atorvastatin modifies the course of MS remains to be investigated.
