OBJECTIVE: To evaluate the presence of autoantibodies to the high mobility group (HMG) structure specific recognition protein I (SSRP1) in sera from patients with systemic lupus erythematosus (SLE) or other rheumatic diseases. METHODS: Antibodies to SSRP1(anti-SSRP1) were measured in sera from patients with SLE, Sjogren's syndrome (SS), ulcerative colitis (UC), systemic sclerosis (SSc), rheumatoid arthritis (RA), and sera from healthy individuals by both an enzyme-linked immunoassay (ELISA) and Western blotting (WB) using the recombinant SSRP1 N-terminus as antigen. RESULTS: We found 28.8% of the sera from patients with SLE contained anti-SSRPI by both ELISA and WB assay, compared to 8.3% of the sera from healthy individuals. When the 40 sera from patients with other autoimmune diseases were tested, only 2 sera (5%) from individuals with SS showed a moderate reactivity to SSRPI in both ELISA and WB assays. CONCLUSION: The results show that anti-SSRPI can be identified in sera from patients with SLE, but not with other rheumatic diseases and may thus help the diagnosis of SLE in the presence of appropriate clinical findings.

Abstract

OBJECTIVE: To evaluate the presence of autoantibodies to the high mobility group (HMG) structure specific recognition protein I (SSRP1) in sera from patients with systemic lupus erythematosus (SLE) or other rheumatic diseases. METHODS: Antibodies to SSRP1(anti-SSRP1) were measured in sera from patients with SLE, Sjogren's syndrome (SS), ulcerative colitis (UC), systemic sclerosis (SSc), rheumatoid arthritis (RA), and sera from healthy individuals by both an enzyme-linked immunoassay (ELISA) and Western blotting (WB) using the recombinant SSRP1 N-terminus as antigen. RESULTS: We found 28.8% of the sera from patients with SLE contained anti-SSRPI by both ELISA and WB assay, compared to 8.3% of the sera from healthy individuals. When the 40 sera from patients with other autoimmune diseases were tested, only 2 sera (5%) from individuals with SS showed a moderate reactivity to SSRPI in both ELISA and WB assays. CONCLUSION: The results show that anti-SSRPI can be identified in sera from patients with SLE, but not with other rheumatic diseases and may thus help the diagnosis of SLE in the presence of appropriate clinical findings.
