Abstract

Objective. To determine the frequency, the clinical and laboratory associations, and the impact on survival of anti-dsDNA, anti-Sm, anti-nRNP, anti-Ro, and anti-La in patients with systemic lupus erythematosus (SLE). Methods. The clinical and laboratory features of 94 patients with SLE tested for anti-dsDNA, anti-nRNP, anti-Sm, anti-Ro and anti-La were studied. Survival analyses were performed by the Kaplan Meier method. Results. Anti- Ro, anti-nRNP and anti-Sm were found with lower frequency in our patients compared to other reports. There was a higher frequency of anti-Sm (19.5 vs 10%, p = 0.0093) and anti-nRNP positivity (29.2 vs 7.5%, p = 0.006) among African American patients compared to Caucasian patients. No clinical or laboratory associations were found with any of the autoantibodies. Patients had a mean followup up 11.8 years. There were no protective or negative effects of the different autoantibodies on the probability of survival of the patients studied. Conclusion. Our study failed to demonstrate the impact of the autoantibodies studied in the survival of our patients.
