[Focus on dehydroepiandrosterone (DHEA)].
Secreted by the adrenal cortex, DHEA exerts its action either indirectly in peripheral tissues after its conversion to androgens and estrogens, or directly as a neurosteroid through the interaction with neuronal receptors. Analyses of randomized studies show that treatment with DHEA improves well-being and fatigue in patients with adrenal insufficiency and reduces disease activity in women with systemic lupus erythematosus. Interesting results have also been observed in the treatment of depressive disorders, but these studies require confirmation. In contrast, there is neither justification for DHEA supplementation in healthy elderly subjects nor clear evidence for beneficial effects of DHEA on muscle function, bone metabolism or cognition. Finally, there is no guarantee with regard to the quality of the product or its safety during long term use.
