Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The SLE pathogenesis involves multiple cellular components of the innate and immune systems, presence of autoantibodies and immune complexes, engagement of the complement system and cytokine dysregulation (3). About 180 autoantibodies have been identified in SLE patients, 102 of which are reported to have an organ-specific correlation with SLE disease identified in SLE patients, with SLE disease activity (4). However, with the exception of autoantibodies such as antinuclear antibody (ANA), anti double stranded DNA (dsDNA), anti-smith and antiphospholipid antibodies, currently proposed by the American college of rheumatology (ACR) (5)

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Anti-ribosomal P(Anti-Rib-P) antibody, routinely tested in SLE, targets a homologous 22-amino acid C-terminal (C-22) sequence shared by three ribosomal phosphoproteins known as P0, P1, and P2 (8).
The prevalence of anti-Rib-P antibody is about 15-40% in SLE patients and varies with the ethnicity, disease activity and detection method (9). Studies have disclosed that anti-P antibodies react with activated T cells but not with B cells, suggesting possible direct effects of anti-P antibodies on immune regulation (10).
