Recent views on autoimmune diseases invoke generalized but specific perturbations in antibody repertoires, rather than the clonally restricted or non-specific polyclonal alterations proposed thus far. The present experiments analyse serum antibody reactivities in 24 systemic lupus erythematosus (SLE) patients and 17 healthy controls, using a method that quantitatively scores a large number of antibody reactivities and allows for multiparametric statistical analyses. The results show global but relatively specific perturbations in SLE antibody repertoires, and identify novel disease-associated reactivity patterns. Furthermore, a time series analysis of serum antibodies over 3 months demonstrates instability of natural antibody repertoires in individual SLE patients, contrasting with their remarkable conservation in healthy donors. Moreover, the method used clusters controls and patients independently, and might prove of diagnostic value, once large data bases are established. [ABSTRACT FROM AUTHOR] |
