Abstract

Rheumatoid arthritis (RA) is a chronic inflammatory and systemic disease characterized by endothelial activation. The main objective of this study was to verify the profile of cell adhesion molecules (CAM) in RA patients, and the influence of metabolic syndrome (MetS) and drugs used in the treatment of RA in this profile. A second objective was to propose models of prediction of activity in RA using these biomarkers. A total of 115 healthy individuals and 144 RA patients were enrolled. Disease activity was determined by DAS28 (disease activity score 28) based on erythrocyte sedimentation rate (DAS28-ESR) or C-reactive protein (DAS28-CRP). Serum CAM and plasminogen activator inhibitor type-1 (PAI-1), anthropometric and immunological parameters were measured. Vascular cell adhesion molecule-1 (VCAM-1) was significantly decreased, and PAI-1 was significantly higher in RA patients as compared to controls. Binary logistic regression analysis showed that VCAM-1, CRP, and tumor necrosis factor-α (TNF-α) predicted RA with a sensitivity of 95.9% and a specificity of 89.5%. 42.9% of the variance in DAS28-ESR and 49.2% of the variance in DAS28-CRP are explained by increased PAI-1, TNF-α, body mass index (BMI) and decreased platelet endoth...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
