Overview

Functional autoantibodies in systemic sclerosis (SSc) pathogenesis. Functional autoantibodies could represent a significant piece in the puzzle of SSc pathogenesis and may open new gateways and opportunities for therapeutic intervention. PubMed, Curr Rheumatol Rep, 2015 May;17(5):505.

ESR: Erythrocyte Sedimentation Rate

ESR: Erythrocyte Sedimentation Rate. There are different methods of obtaining the SED rate--such as Westergren, Cutler, Wintrobe, and Smith--and what is considered normal will depend on the method used. This test can be used to monitor inflammatory or cancerous diseases. It is a screening test, which means it cannot be used to diagnose a specific disorder. Medline Plus.

Antibodies in Localized Scleroderma (Linear and Morphea)

Antinuclear Antibodies

IgG or IgM anti-Cu/Zn SOD antibody was detected in the serum of 89% of localized scleroderma patients, especially 100% of patients with generalized morphea, the severest form of localized scleroderma, but was positive only in the serum of less than 15% of patients with other autoimmune disorders, including systemic sclerosis, systemic lupus erythematosus, dermatomyositis, and autoimmune bullous disorders. Journal of Investigative Dermatology. (Also see Generalized Morphea)

Antinucleosome

Antinucleosome antibody is a major autoantibody in localized scleroderma. Although antinucleosome antibody was not specific to localized scleroderma, its high prevalence in localized scleroderma indicates that antinucleosome antibody is a major autoantibody in this disease. PubMed, Br J Dermatol. (Also see Localized Scleroderma)

Lupus and Antibodies

Antibodies in Lupus. There are over 100 antibodies associated with lupus. ISN.

Elucidation of the potential disease-promoting influence of IgM apoptotic cell–reactive antibodies in lupus. Apoptotic cell-reactive IgM antibodies may be potentially capable of influencing the course of systemic autoimmune disease by affecting both innate and adaptive immunity. Lupus, 01/06/2016.
