Adrenocorticotropin, glucocorticoid, and androgen secretion in patients with new onset synovitis/rheumatoid arthritis : Relations with indices of inflammation
To determine whether alterations in adrenocortical function occur early in the development of inflammatory joint disease, we examined patients with new onset synovitis ( or =45 yr), but similar levels of ACTH, cortisol, DHEA, DHEA sulfate, and total testosterone. In addition, the positive correlatio...

Zusammenfassung: | To determine whether alterations in adrenocortical function occur early in the development of inflammatory joint disease, we examined patients with new onset synovitis ( or =45 yr), but similar levels of ACTH, cortisol, DHEA, DHEA sulfate, and total testosterone. In addition, the positive correlations between ACTH-cortisol, ACTH-DHEA, and cortisol-DHEA, observed in the normal controls, were weakened or abolished in the patients (both total and RA subset). No positive relations between inflammatory indices and ACTH or cortisol were noted, yet an inverse correlation between these indices and DHEA and testosterone was observed. Moreover, a steeper age-associated decline in DHEA was observed in our cross-sectional sample of patients with new onset synovitis. We conclude that patients with synovitis (including those fitting criteria for RA) have adrenocortical hormone alterations within a year of disease onset. Paradoxically, these patients have no positive relation between indices of inflammation and ACTH or cortisol, but rather serum androgen levels are inversely correlated with these indices. In addition, the relations between ACTH, the classic stimulus of cortisol and adrenal androgens, and these hormones are weakened or abolished, whereas the negative relation between age and zona reticularis function is steeper than that of controls. |
