Glucocorticoid receptor up-regulation in early rheumatoid arthritis treated with low dose prednisone or placebo.

Abstract

The GR number in the PBMC of early RA patients did not predict which patients would be prednisone responders based on clinical or radiological parameters. However, the up-regulation of the GR number in PBMC in early RA patients towards the GR number of healthy subjects during the first two years of their disease course seems to reflect a recovery or compensatory mechanism as a response to an ongoing inflammatory process. This recovery may be not enough to efficiently control the inflammatory situation.
