Main Serological Markers of Systemic Rheumatic Autoimmune Diseases

View through CrossRef
Abstract: Systemic rheumatic autoimmune diseases are complex chronic inflammatory disorders, generally with impairment of joins and systemic manifestations. This study is a literature review about the main serologic markers used in the screening of these illnesses. The assessment of the presence of autoantibodies is an essential component in the initial diagnosis of autoimmune diseases. The production of these antibodies occurs via humoral immune response against self-antigens, and these antibodies are often present in the serum of patients diagnosed with autoimmune illness. Each antibody has a different function and specificity and this is directly associated with clinic manifestations and disease course. The main markers detected in rheumatology have antinuclear, prothrombotic and inflammatory action; therefore depending on the complexity of the illness, several markers can be identified, assisting both in diagnosis and prognosis disease.
