Abstract
A biomarker is a biological parameter that can be measured in blood or other body fluids or tissues and used as a sign of a normal or abnormal process, or of a condition or disease. In medicine, a biomarker can be used to diagnose a disease, to establish its prognosis or as a surrogate marker of outcome in research. In recent years, there has been strong interest in discovering new biomarkers, as well as in the development of new uses for well-known biomarkers in distinct diseases. In this article, the utility of several biomarkers not routinely used in rheumatology (procalcitonin, natriuretic peptides and cardiac troponins) in the diagnosis and follow-up of patients with systemic autoimmune diseases is reviewed.
