[Detection of serum catalase antibodies in patients with inflammatory rheumatic diseases by immobilized magnetic sorbents].
Sixty patients with systemic lupus erythematosus, 48 patients with rheumatoid arthritis, and 30 healthy individuals (a control group) were examined. Modified procedures for enzyme immunoassay (EIA) and immunofluorescence (IF) assays with an immobilized magnetic sorbent (MS) based on catalase as an antigenic matrix were used to detect catalase antibodies (Ab). The application of immobilized MSs and a photoelectric digital display attachment to a fluorescence microscope permits measurements of Ab to soluble antigens (catalase) in the IF assay. Nevertheless, for detection of catalase Ab in laboratory practice, preference should be given to EIA using a MS as a more sensitive procedure.
