Abstract

Systemic Lupus Erythematosus is an autoimmune multisystem disorder with protean manifestations and variable behavior. The main objectives of this study are to verify the association of ribosomal anti-P
antibodies with neuropsychiatric lupus manifestations and to find out the relationship of ribosomal anti-P antibodies with other autoimmune parameters of lupus. Ribosomal anti-P antibodies were evaluated in the serum of 41 systemic lupus erythematosus (SLE) patients as well as ANA, dsDNA, anti- Sm, anti-SSA, anti-SSB, anti-histone by an indirect ELISA technique. Apart from Immunological tests, we also studied hematological parameters and biochemical parameters. Of the 41 SLE patients, ribosomal anti-P antibodies were significantly elevated in the sera of 6 lupus patients suffering from severe depression, anxiety, headache and lupus psychosis. Immunological parameters like ANA,
dsDNA were positive in 100% of the Anti-Rib-P positive patients; but 66.6% were positive for SSA, only 33.3% for Sm, and none of them were positive for anti-histone and SSB. Biochemical parameters like
urea, creatinine were higher than the normal range in 66.6% of the anti-P positive lupus patients, suggestive of lupus nephritis.
