Inflammation is the hallmark of rheumatic diseases. Tissue injury response promotes several modifications, which result in elimination of the offending agent, limitation of tissue damage, and restoration of affected structures. Such modifications depend on the increase or decrease of the serum concentration of certain proteins known as inflammatory biomarkers. Laboratory analysis of these markers assists in monitoring disease activity and treatment response. Rheumatologists have available methods that evaluate inflammatory reaction such as C-reactive protein, erythrocyte sedimentation rate, and protein electrophoresis, among others. In this paper, we review some of those biomarkers and their use in rheumatic diseases.
