Common questions

What does Ro52 positive mean?

What does Ro52 positive mean?

Background. Ro52 is an interferon-inducible protein of the tripartite motif family. Antibodies against Ro52 have been described in patients with different autoimmune diseases, such as systemic lupus erythematosus and Sjögren’s syndrome, that are often associated with anti-Ro60 antibodies.

What is SS a 60?

SS-A 60 is a component of the human cytoplasmic ribonucleoprotein complex. The proteins SS-A 60 and SS-A-52 bind to smaller RNAs and ribonucleoprotein particles in the cell nucleus and the cytoplasm. Autoantibodies against SS-A 60 are primarily found in cases of Sjögren’s syndrome and lupus erythematosus.

What is anti SSA and SSB?

Anti‐SSA and ‐SSB antibodies are clinically important antinuclear antibody (ANA) in patients with systemic rheumatic diseases. These antibodies are found in Sjögren’s syndrome (SS), as well as other systemic autoimmune diseases (ADs), such as systemic lupus erythematosus (SLE), myositis, scleroderma, etc.

Can Sjogren’s go away?

There is no cure for Sjögren’s syndrome. As with other autoimmune diseases, the severity of Sjögren’s varies from person to person. Many patients have a mild disease that only affects the eyes and mouth. Others have symptoms that wax and wane in severity or may even go into remission.

What is SS B antibody positive?

A positive result for SS-B/La antibodies is consistent with connective tissue disease, including Sjogren syndrome and lupus erythematosus.

What does Sjögren’s anti ss-A mean?

Elevated anti-SS-A antibodies and/or anti-SS-B antibodies indicate inflammatory connective tissue disease, especially Sjögren’s syndrome. Your healthcare provider might order these tests for you if there is a concern that you could have: Sjögren’s syndrome. Systemic lupus erythematosus (SLE) Rheumatoid arthritis.

Why is it called anti Ro?

In 1969, two separate labs simultaneously identified antigens in the sera of SLE and SS patients. Clark et. al referred to the antigen as Ro, while Alspaugh & Tanand used the term SSA. It was later found that the labs described the same antigen, hence the compound term for the antibody, Anti-SSA/Ro, Anti-Ro/SSA.

Are there any anti-SS-a / ro 60 kDa antigens?

Anti-SS-A/Ro 60 kDa antigens are prevalently found in individuals suffering from Sjiogren Syndrome (SS) and in those with systemic lupus erythematosus (SLE) (7).

Where can I find Ro52 and Ro60 antibodies?

Electronic address: [email protected] Anti-Ro52 (Ro52) and anti-Ro60 (Ro60) antibodies are associated with different clinical entities.

Are there anti-ENA profiles related with anti-SS-a / ro?

Anti-ENA profiles related with anti-SS-A/Ro. The detection of Ro52 and Ro60 according to the presence of SS-B/La, and ANA pattern and titer Anti-ENA profiles related with anti-SS-A/Ro. The detection of Ro52 and Ro60 according to the presence of SS-B/La, and ANA pattern and titer Immunol Lett. 2014 Sep;161 (1):6-12. doi: 10.1016/j.imlet

Is there a link between anti-Ro and anti La?

Levels do not correlate with disease activity. In SLE anti-Ro is not always associated with anti-La.Of particular importance is neonatal lupus erythematosus (including complete congenital heart block) where affected neonates have anti-Ro and anti-La antibodies.
