CRP and systemic lupus erythematosus: The development of glomerulonephritis in SLE was associated with the presence of some specific nephritogenic autoantibodies, such as anti-double-stranded DNA (anti-dsDNA) antibodies (2–4), anti-Sm antibodies, anti-C1q antibodies (5–8), and anti-C-reactive protein (CRP) antibodies (9, 10), whereas more than 150 autoantibodies were reported in SLE.
