Abstract

Rheumatoid arthritis (RA) is frequently associated with organ or non-organ-specific autoantibodies or overt autoimmune disorders. Aim of our study was to assess the prevalence and concentration of a panel of organ-specific autoantibodies in patients with RA and to evaluate their relationship with clinical manifestations and treatment efficacy. Clinical and serological data from 20 patients with active RA (3M/17F), aged from 28 to 80 years and 50 healthy controls were analyzed. All patients fulfilled the 1987 American College of Rheumatology (ACR) classification criteria for RA and were treated with adalimumab and methotrexate. At baseline and after 6 months of therapy we tested anti-thyroid antibodies for thyroperoxidase (TPOAb) and thyroglobulin (TgAb) using an automated immunochemiluminescence assay (Immulite 2000, DPC, Los Angeles, CA), and anti-tissue transglutaminase (anti-tTG) using the ELISA assay (Phadia, Freiburg, Germany). Anti-smooth muscle (SMA), anti-liver kidney microsome (LKM), anti-parietal cells (APCA), anti-mitochondrial (AMA) and anti-liver cytosolic protein type 1 (LC1), anti-adrenal gland (ACA), anti-pancreatic islet (ICA) and anti-steroid-producing cell (stCA) antibodies were analyzed using a commercially ...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
