Specificity of anti-SSB as a diagnostic marker for the classification of systemic lupus erythematosus
The aim of the present study was to investigate the sensitivity and specificity of anti-Sjögren’s syndrome type B (SSB) antibodies for diagnosing systemic lupus erythematosus (SLE) and to understand the correlation between anti-SSB antibodies and the clinical manifestations of SLE.

Sumario: | The aim of the present study was to investigate the sensitivity and specificity of anti-Sjögren’s syndrome type B (SSB) antibodies for diagnosing systemic lupus erythematosus (SLE) and to understand the correlation between anti-SSB antibodies and the clinical manifestations of SLE. A line immunoassay (LIA) was used to detect the presence of serum anti-SSB antibodies in SLE patients. The clinical manifestations of the patients were recorded to enable their correlation with the serum anti-SSB antibodies to be analyzed. In 25.7% of the 74 SLE patients, the serum was positive for anti-SSB antibodies, whereas only 3.3% of the 30 control cases were positive. The specificity of anti-SSB antibodies for detecting SLE was 96.7%. In anti-SSB antibody-positive SLE patients, the incidence of cheek erythema, alopecia, serositis, secondary Sjögren’s syndrome (sSS), leukocytopenia, elevated immunoglobulin (Ig)G and positive presence of anti-Sjögren’s syndrome type A (SSA)60 or anti-SSA52 antibodies was higher than in the anti-SSB antibody-negative group (P<0.05). Anti-SSB antibodies are important for the diagnosis of SLE and are associated with cheek erythema, alopecia, serositis, sSS, leukocytopenia, the elevation of IgG and positive presence of anti-SSA60 or anti-SSA52 antibodies. |
