Androgens in rheumatoid arthritis: when are they effectors?
Neither hormone receptor genes nor plasma androgens seem significantly altered in female subjects before they became affected by rheumatoid arthritis (RA) and, therefore, do not seem to play a role as risk factors for its development. However, serum testosterone levels are inversely correlated with RA activity and dehydro-epiandrosterone sulfate (DHEAS) plasma levels are inversely correlated with both disease duration and clinical severity in patients already affected by active RA. In particular, gonadal and adrenal androgens (that is, testosterone and DHEAS) are significantly decreased in inflamed synovial tissue/fluids during active disease as a consequence of the inflammatory reaction, which supports a pro-inflammatory milieu in RA joints. Recently, male gender has been found to be a major predictor of remission in early RA.
