Abstract

Glucocorticoids are steroid hormones that once bound to their receptor interact with the DNA binding domain. Almost 1000-2000 genes are sensitive to their effects, including immune/inflammatory response genes. However, their role in pathophysiology and therapy is still debated. We performed a literature survey using the key words glucocorticoids, inflammation, autoimmune disease, rheumatology and adrenal glands in order to define important targets for this review on glucocorticoids. Considering endogenous/exogenous glucocorticoids in chronic inflammatory diseases brought up five major points for discussion: inadequately low production of endogenous cortisol relative to systemic inflammation (the disproportion principle); changes of the systemic and local cortisol-to-cortisone shuttle (reactivation and degradation of cortisol); inflammation-induced glucocorticoid resistance; highlights of present glucocorticoid therapy; and the role of circadian rhythms in action of cortisol. Much of this information becomes understandable in the context of neurohormonal energy regulation as recently summarized. The optimization of long-term low-dose glucocorticoid therapy in chronic inflammatory diseases arises from the understanding of the above mentioned aspects. Since glucocorticoid resistance is a consequence of inflammation, adequate anti-inflammatory therapy is mandatory.
