Complete Atrioventricular Block in Adult Sjögren's Syndrome with Anti-Ro Autoantibody
نویسندگان
چکیده
Anti-Ro autoantibody is associated with Sjögren's syndrome (SS), systemic lupus erythematosus (SLE), and neonatal lupus syndrome (i.e., congenital complete heart block in newborns). Generally, the adult atrioventricular (AV) node is believed to be relatively resistant to the scarring effects of anti-Ro/anti-La autoantibodies. However, there have been some reports of adult complete AV block in SS and SLE patients. Here, we report a case of complete heart block in primary SS with anti-Ro autoantibodies, with no other risk factor for the development of heart block, and review their etiological association.

Second-degree atrioventricular block as an early manifestation of adult systemic lupus erythematosus.
Second-degree atrioventricular (AV) block had not been reported as an early manifestation of adult systemic lupus erythematosus (SLE). An 18-year-old woman of SLE presented with asymptomatic second-degree AV block with 2:1 conduction block on electrocardiogram (ECG) during admission. Serologic tests were negative for anti-Sjögren's syndrome A (anti-SS-A/Ro) and anti-SS-B/La antibodies, but posi...

BACKGROUND Until recently, anti-SSA/Ro antibodies were not considered pathogenic for severe heart disease in adults. Prolongation of the mean QTc interval in electrocardiograms of adult patients with anti-SSA/Ro-positive connective tissue disease has been reported and could contribute to complex arrhythmias in such patients. Furthermore, complete heart block may also be related to these autoant...

Idiotypes and antiidiotypes are thought to be important immune regulators and have provided clues for the origin and pathogenicity of autoantibodies. Many lupus and Sjögren's syndrome patients, as well as most neonatal lupus infants with congenital heart block or dermatitis, have antibodies to the ribonucleoprotein Ro/SSA, which is one of a group of RNA-protein autoantigens commonly found in hu...

Background: Sjögren’s syndrome is the second most common systemic autoimmune disease after rheumatoid arthritis, RA, with a prevalence of about 0.5% in the general population. It occurs primarily in perimenopausal women (at a ratio of women to men of 9: 1) Sjögren’s syndrome is characterized by lymphocytic infiltration to exocrine glands. The specific autoantibodies of this syndrome are against...
متن کاملPossible association between anti-Ro antibodies and myocarditis or cardiac conduction defects in adults with systemic lupus erythematosus.
In view of the association of congenital heart block with maternal antibody to cellular antigen Ro (SSA), and one report linking anti-Ro with myocarditis in a patient with myositis an association between anti-Ro antibodies and cardiac disease was sought in adults with systemic lupus erythematosus (SLE). Among 67 patients with SLE, of whom 36 were anti-Ro positive, a significantly higher prevale...
