Abstract

Interferons (IFNs) have immunomodulatory properties such as direct increase in the production of pathogen autoantibodies, enhanced cytotoxic T cell and B cell activities, inhibition of T suppressor cell function and induction of HLA class I antigen expression. These actions of IFN induce autoimmune disorders including autoimmune thyroiditis, hemolytic anemia and thrombocytopenia, SLE, rheumatoid arthritis and psoriasis, however, these autoimmune diseases except for autoimmune thyroiditis, are rare among side effects of IFN therapy. Most of the patients showing these autoimmune disorders during IFN treatment have predisposal immunological abnormalities such as positive ANA and antithyroidal autoantibodies. We described here autoimmune disorders during and after IFN treatment among 1023 cases with chronic active type C hepatitis. The cases with SLE, thrombocytopenic purpura, rheumatoid arthritis and psoriasis showed good prognosis after cessation of IFN administration.

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.
