Background & objectives: Rheumatoid artherits (RA) is a refractory disease and the imbalance between pro- and anti-inflammatory cytokines in favor of pro-inflammatory cytokines has been implicated in pathogenesis of RA. In this context, the aim of the present study was to compare the anti-inflammatory and antioxidant effects of candesartan, an angiotensin-receptor blocker, and atorvastatin in RA patients. Methods: In this single-blinded parallel randomized placebo controlled study, the patients recruited between December 2017 and May 2018 were categorized into three groups: group 1 included 15 RA patients who served as control group and received traditional therapy (+ placebo); group 2 included 15 RA patients who received traditional therapy + candesartan (8 mg/day); and group 3 included 15 patients who received traditional therapy + atorvastatin (20 mg/day) for three months. Clinical status in RA patients was evaluated by Disease Activity Score 28 (DAS28), Health Assessment Questionnaire-Disability Index (HAQ-DI) and morning stiffness before and three months after treatment. All groups were subjected to biochemical analysis of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), tumour necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and malondialdehyde (MDA) before and three months after treatment. Results: Both candesartan and atorvastatin treated groups showed significant decrease in serum levels IL-1β and TNF-α, acute-phase reactants (CRP and ESR), number of swollen joint and patient global assessment. This was also associated with improvement in disease activity and quality of life regarding DAS28 and HAQ-DI as compared to baseline data and the control group. Atorvastatin group showed significant decrease in the serum level of oxidative stress marker (MDA). Interpretation & conclusions: Both candesartan and atorvastatin showed anti-inflammatory effect and immunomodulatory effects leading to improvement in clinical status and disease activity in RA patients. However, atorvastatin was superior to candesartan through its anti-oxidant effect.
