Malondialdehyde-acetaldehyde antibody concentrations in rheumatoid arthritis and other rheumatic conditions

With the possible exception of the IgA isotype, serum anti-MAA antibodies measured with currently available assays do not appear to adequately discriminate RA from other rheumatic conditions. With the identification of specific proteins that are MAA-modified in diseased tissues and requisite assay refinement, anti-MAA antibody holds potential promise as a biomarker in RA.
