PG - 217-25 LID - 10.1159/000439538 [doi] AB - BACKGROUND/AIMS: Rheumatoid arthritis (RA) is a disabling autoimmune disease for which most current treatments cause massive complications, thereby limiting treatment dose and duration. The anti-arthritic effects of the 3-hydroxy-3-metylglutary-CoA reductase inhibitor, simvastatin, and the natural flavonoid, hesperidin, were investigated against complete Freund's adjuvant-induced RA in rats. METHODS: A normal control group, an arthritis control group, 2 reference treatment groups receiving dexamethasone (1.5 mg/kg/day) and methotrexate (1 mg/kg/day), and 2 treatment groups receiving simvastatin (0.5 mg/kg/day) and hesperidin (200 mg/kg/day) were included in the study. Serum rheumatoid factor, matrix metalloprotinease-3 (MMP-3) and cartilage oligomeric matrix protein (COMP) as specific rheumatoid biomarkers, serum immunoglobulin G (IgG) and antinuclear antibody (ANA) as immunological biomarkers, serum tumor necrosis factor-alpha and interleukin-10 as immunomodulatory cytokines, serum myeloperoxidase (MPO) and C-reactive protein as inflammatory biomarkers, and malondialdehyde (MDA) and glutathione (GSH) as oxidative stress biomarkers were assessed, supported by joint and spleen histopathological study. RESULTS: Simvastatin significantly improved all the measured biomarkers, with MMP-3, COMP, and GSH restored to normal levels. Hesperidin significantly improved all the measured biomarkers, with COMP, IgG, ANA, MPO, MDA and GSH restored to normal levels. CONCLUSION: Simvastatin and hesperidin may be promising protective agents against RA through immunomodulatory, anti-inflammatory and antioxidant potentials. CI - (c) 2015 S. Karger AG, Basel.
