Clinical Trial Summary

Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects the joints, causing pain, edema, physical disability and poor quality of life. In addition, RA patients are at increased risk of developing cardiovascular disease (CVD) and premature death. The most effective pharmacological treatment is the use of biological agents that inhibit the action of specific substances, such as interleukin 6 (IL-6) and tumor necrosis factors (TNF). Physical exercise is considered a first-line non-pharmacological treatment in RA, improving inflammatory and metabolic profile, functional capacity, fatigue and preventing the onset of CVD. There is evidence that IL-6, when secreted as a result of exercise, brings several benefits. However, there is no study investigating the interaction between biological IL-6 blocking agents and exercise on metabolic responses, such as insulin sensitivity and glucose uptake, in patients with RA. To answer this question, adult women diagnosed with RA and healthy controls will be recruited for an acute session of exercise. RA patients will be divided into 2 groups, according to the pharmacological treatment (tocilizumab or anti-TNF). The acute responses of insulin sensitivity after an acute session of exercise will be assessed by the hyperinsulinemic euglycemic clamp, and the molecular pathways will be assessed by muscle biopsy and gene and protein expression analysis. Positron emission tomography-magnetic resonance imaging (PET/MRI) will be performed to quantify skeletal muscle glucose uptake.
