(1) Background: Marine n-3 polyunsaturated fatty acids (PUFA) and ɤ-linolenic acid (GLA) are well-known anti-inflammatory agents that may help in the treatment of inflammatory disorders. Their effects were examined in patients with rheumatoid arthritis; (2) Methods: Sixty patients with active rheumatoid arthritis were involved in a prospective, randomized trial of a 12 week supplementation with fish oil (group I), fish oil with primrose evening oil (group II), or with no supplementation (group III). Clinical and laboratory evaluations were done at the beginning and at the end of the study; (3) Results: The Disease Activity Score 28 (DAS 28 score), number of tender joints and visual analogue scale (VAS) score decreased notably after supplementation in groups I and II (p < 0.001). In plasma phospholipids the n-6/n-3 fatty acids ratio declined from 15.47 ± 5.51 to 10.62 ± 5.07 (p = 0.005), and from 18.15 ± 5.04 to 13.50 ± 4.81 (p = 0.005) in groups I and II respectively. The combination of n-3 PUFA and GLA (group II) increased ɤ-linolenic acid (0.00 ± 0.00 to 0.13 ± 0.11, p < 0.001), which was undetectable in all groups before the treatments; (4) Conclusion: Daily supplementation with n-3 fatty acids alone or in combination with GLA exerted significant clinical benefits and certain changes in disease activity.
Rheumatoid arthritis is a chronic inflammatory disease. Reactive oxygen species have been considered as aggravating factors for autoimmune diseases. Fatty acids had been linked in reduction of various diseases by augment of their antioxidant potential and antiinflammatory mechanisms. The aim of this study was to assess the oxidative status in patients with rheumatoid arthritis who used concentrated fish oil only or concentrated fish oil in combination with evening primrose oil in a period of 3 months. Subjects were divided into three groups. The group I consists of patients who had been taking only their regular rheumatologic therapy; group II, patients who had been taking concentrated fish oil; and group III, patients who had been taking concentrated fish oil and evening primrose oil. Peripheral blood samples were used for all the assays. We assessed the following oxidative stress markers: index of lipid peroxidation (thiobarbituric acid-reactive substances (TBARS)), hydrogen peroxide (H2O2), superoxide anion radical (O2 (-)), nitric oxide (NO), superoxide dismutase activity (SOD), catalase activity (CAT), and glutathione levels (GSH) in erythrocytes. There were no statistically significant changes for any of the oxidative stress parameters in group I. In group II, levels of TBARS, NO2 (-), and GSH were increased, while levels of H2O2 decreased. Increased values of TBARS, NO2 (-), and SOD were found in group III. Our findings indicate that intakes of fish oil and evening primrose oil may be of importance in mitigation of inflammation, disease activity, and oxidative stress biomarkers, through increased activities of antioxidant enzymes.
In this study, we investigated the concentration of serum homocysteine (Hcy) in patients with rheumatoid arthritis (RA) compared with the control group and the connection between homocysteine and parameters of inflammation and disease activity. Sixty RA patients and 20 healthy controls were included in the study, and clinical examination and investigation were performed during which disease activity was assessed. Peripheral blood samples were used for all of the assays. Levels of Hcy were 33% higher in the RA patients than in the control subjects (mean +/− SD 11.79±3.72 μmol/L versus 8.90±1.38 μmol/L; p< 0.01). A significant correlation was found between parameters of inflammation (C-reactive protein) and homocysteine in patients (r=0.322, p=0.012). Patients with high disease activity had a significantly greater increase in homocysteine (p<0.05). An increase in plasma homocysteine in RA patients is related to the parameters of inflammation and disease activity. Elevated Hcy levels occur commonly in patients with RA and may explain some of the increased cardiovascular mortality seen in RA patients.
