Abstract


Rheumatoid arthritis (RA) is a chronic autoimmune disease, which can lead to joint destruction and disability. Pannus formation due to chronic synovitis is the hallmark of RA. Oxidative stress as a consequence of immune cell activation and disease-modifying anti-rheumatic drugs can prevent inflammation and tissue destruction. Silymarin, an antioxidant extract from Silybum marianum, has been traditionally used for the treatment of liver diseases for decades. In the present non-randomized single-arm clinical trial (NRSACT) study we evaluated the effects of silymarin tablet (Livergol®) on inflammatory markers in stable RA patients. Disease activity score (DAS-28) was measured before and after adding silymarin to standard drug regimen used for controlling inflammation in RA patients. Silymarin significantly reduced the DAS28 related symptoms in 44 RA patients after 90 days (3.02±0.98 versus 2.3±0.74, p<0.001). The exact mechanism of therapeutic effects of silymarin in RA patients is not clear but it could be as the results of its anti-inflammatory and anti-oxidative properties. Conducting the study on larger number of patients and also measuring cytokines levels including TNF-α and IL-1β may clarify the underlying mechanisms of the anti-inflammatory effects of silymarin in RA patients.
