The thiol status of patients with rheumatoid arthritis is significantly different from that of controls. Plasma thiol levels are lower, albumin thiol reactivity is altered and intracellular thiol levels measured after hemoglobin precipitation are increased. These variations correlate with other indices of disease severity and are one measure of a disturbance in the degree of oxidation of the blood. Penicillamine, in common with other effective therapeutic agents, produces an increase in serum thiol concentration. It causes a greater effect on serum thiol reactivity than other drugs and in particular it increases 'fast reacting' thiol levels without significantly altering the 'slow reacting' thiol level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
