Indication: Associated with Systemic Lupus Erythematosus (SLE)

Background: Antibodies to ribosomes, particularly to ribosomal ribonucleoprotein (rRNP) are associated with SLE (5-12%of patients). The majority of patients with neuropsychiatric lupus will be positive for ribosomal P antibodies with the level reported to correlate with disease activity. Ribosomal P antibodies can also be found in rheumatoid arthritis. Antibodies recognize three phosphoproteins (P0, P1 and P2), antigens are distinct from antibodies to nuclear RNP’s.
