Abstract:
:The aim of this study was to evaluate the involvement of TNF-α and insulin resistance (IR) in the inflammatory process, oxidative stress, and disease activity in patients with rheumatoid arthritis (RA). This cross-sectional study included 270 subjects (control group, n = 97) and RA patients (n = 173). RA patients were divided into four groups: the first group without IR and not using antitumor necrosis factor-α (TNF-) (G1, IR- TNF-); the second group without IR and using anti-TNF-α (G2, IR- TNF+); the third group with IR and not using anti-TNF-α (G3, IR+ TNF-); and the fourth group with IR and using anti-TNF-α (G4, IR+ TNF+). G3 and G4 had higher (p < 0.05) advanced oxidation protein products (AOPPs) and oxidative stress index (OSI) compared to G1. G4 group presented higher (p < 0.05) AOPPs and OSI than G2. TRAP was significantly lower in G3 compared to G1. Plasma TNF-α levels were significantly higher in G4 and G2 compared to G1 (p < 0.0001) and G3 (p < 0.0001 and p < 0.01, resp.). The presence of insulin resistance was robustly associated with both oxidative stress and TNF-α levels. More studies are warranted to verify if IR can be involved in therapeutic failure with TNF-α inhibitors. This trial is registered with Brazilian Clinical Trials Registry Register number RBR-2jvj92.
