Modern possibilities and prospects in the treatment of adrenal insufficiency

Adrenal insufficiency (AI) is a life-threatening disease characterized by a decrease in the production of hormones by the adrenal cortex and requires lifelong replacement therapy with glucocorticoids (GCs) and, in some cases, mineralocorticoids (MCs). The number of individuals with primary and secondary AI in Europe is estimated at 20-50 per 100 thousand people, the increase in the number of cases of this disease in the world may be partly due to the rapid increase in the frequency of use of GC in various clinical strategies, including in oncological diseases.In AI, hormone replacement therapy is vital, but long-term use of GC may be associated with various adverse effects, especially at non-physiological concentrations of GC. This review provides a brief overview of the current therapeutic possibilities of AI hormone therapy, which contributes to the prevention of the development of adrenal crises, as well as promising opportunities for more effective imitation of the physiological profile of cortisol, aimed at preventing the development of undesirable effects of therapy. Several different forms of AI are currently available, differing in profile, duration of action, and route of administration. The most preferred currently in the treatment of AI are GCs with a short half-life, which provides a more manageable action profile and a lower risk of side effects. Promising substitution therapy options include modified-release hydrocortisone preparations, as well as new methods of drug administration using an insulin pump, which will better mimic the physiological effects of endogenous cortisol.
