The aim was to determine whether the autoantibody profile in Black female lupus patients is associated with clinical subsets, fluctuates over time and/or reflects disease activity. A clinical comparison with Caucasian and Asian patients matched for age of onset and disease duration was also undertaken. Up to seven serial bleeds from Black female lupus patients who had been followed up for periods of 3.15 yr were tested for antibodies to Ro/SSA, La SSB. Sm, RNP and ribosomal P using ELISA research assays. Significant differences in both clinical and serological profiles between the ethnic groups were found. Varying aspects of disease activity were linked to anti-DNA (renal, cardiovascular, global score), anti-ribosomal P (musculoskeletal, haematology) and anti-Sm (general) antibodies. There are differences in clinical and serological profiles amongst systemic lupus erythematosus patients of different ethnic origin. However, using the BILAG system, relatively few antibodies were found to reflect disease activity accurately in serial measurements.
