title: [Anti-ribosomal antibodies as activity markers in systemic lupus erythematosus].
abstract: OBJECTIVE
  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.
  
  
  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.
