The aim of this study was to examine both enzymatic and non-enzymatic antio
xidant status in a select group of children with juvenile rheumatoid arthri
tis (JRA), living in Cairo, Egypt. The plasma concentrations of albumin, ce
ruloplasmin, vitamin C, vitamin E as well as erythrocyte superoxide dismuta
se and whole blood glutathione peroxidase activities were all significantly
decreased in the presence of JRA compared to those without JRA. Unlike the
se antioxidant factors, vitamin A and its carrier (e.g. retinol binding pro
tein), which have very little or no antioxidant property, remained unaffect
ed by JRA. These results suggest that the children with JRA are subject to
oxidative stress.
