ALMEIDA, D. et al. Anti-ribosomal antibodies as markers of activity in patients with erythematosus systemic lupus (ESL). []. , 19, 2, pp.31-33. ISSN 0212-7199.

Objectives: a) to determine the prevalence of anti-ribosomal P antibodies in patients with ESL in our setting; b) to determine if there are associations between clinical signs of ESL and these autoantibodies; c) to analyze if there is any correlation between the presence of anti-P in patients with ESL and the results of other routine lab tests; and d) to assess the usefulness of implementing as routine test the determination of anti-P antibodies.  Material and methods: The study included 60 patients diagnosed of ESL and 61 healthy subjects as the control group. ELISA was used to determine anti-ribosomal antibodies. Chi-square, Fisher and Student t tests were used for the statistical analyses.  Results: Of the 60 patients with SLE, 29 (48%) had anti-P antibodies as determined by ELISA. No association was observed between the presence of anti-P antibodies and psychosis, depression, hepatic failure, renal failure or any other clinical signs of ESL.  A correlation was found between the levels of anti-P antibodies as determined by ELISA and anti-histone, ANA and AMA antibodies.  Conclusions: The prevalence of anti-P antibodies was high among our ESL patients (48%). Their presence was not significantly associated with any clinical sign; however, an association was found with other lab markers related to the presence of active disease.
