Detail Autoantibodies to Topoisomerase I in A Patient with Systemic Lupus Erythematosus without Features of Scleroderma   Oleh:  Stojanov, L ; Satov, M ; Dooley, MA ; Kuwana, M ; Jennette, JC ; Reeves, WH Jenis: Article from Journal Dalam koleksi: Lupus vol. 4 no. 4 (1995), page 314-317. Topik: Anti-Topoisomerase I Antibodies; Anti-RNA Polymerase II Antibodies; Anti-Nuclear Antibodies Fulltext: Lupus-1995-Stojanov-314-7.pdf (472.04KB) Isi artikel We report a woman with systemic lupus erythematosus (SLE) with diffuse proliferative glomerulonephritis and anti-dsDNA antibodies whose serum contained autoantibodies specific for the phosphorylated form of RNA polymerase II (RNAP IIO), Su and ribosomal P antigen, as well as anti-topoisomerase I antibodies, a marker for scleroderma (SSc). Over 6 years, the patient exhibited clinical manifestations consistent with SLE without clinical evidence of scleroderma. The reactivity of her serum autoantibodies with the phosphoproteins ribosomal P, topoisomerase I, and RNAP IIO is consistent with recognition of autoepitopes comprised in part of phosphate groups. This may explain the unexpected coexistence of marker autoantibodies for SLE and scleroderma, possibly with implications for the mechanisms of autoantibody generation.
