[Regulatory R proteins and lipid peroxidation in rheumatoid arthritis]

Levels of R proteins (RP) and activity of lipid peroxidation (LPO) were measured in 209 patients with RA. It was noted that RP levels and LPO activity correlated with the activity of inflammation. A rapid RA progression was characterized by higher RP levels and LPO activity, while polyarthritis by more intensive RP metabolism and LPO. A comprehensive study of RP and LPO in RA patients may facilitate prognosis of the destruction rate.
