We performed this study to measure the Tumor Necrosis Factor-alpha (TNF-α) plasma level and to survey its correlation with disease activity in the newly diagnosed Rheumatoid Arthritis (RA) patients and those who were under treatment with the combination of Disease-Modifying Anti-Rheumatic Drug (DMARD) plus Prednisolone (PSL).We enrolled 30 newly diagnosed RA patients who received no treatment regarding their disease, 30 patients under treatment with the combination of Methotrexate (MTX) + Hydroxychloroquine (HCQ) + PSL and 30 healthy subjects in this case-control study from September 2017 to December 2017. The level of plasma TNF-α was measured by enzyme-linked immunosorbent assay (ELISA) in each group. For assessment of disease severity, we used Disease Activity Score-28 (DAS-28) formula, and regarding DAS-28, we divided patients into four groups, including remission, low, moderate and high disease activity. There were no significant differences in the plasma level of TNF-α between the newly diagnosed RA patients and subjects who received MTX + HCQ + PSL, as well as healthy controls (p>0.05). There was a significant correlation between plasma levels of TNF-α and DAS-28 in the newly diagnosed patients with RA (r = 0.594, P = 0.001). Targeting TNF-α at the early stage of RA could have more beneficial effects on the amelioration of disease activity.
