The undesirable endocrine effects associated with pharmacological therapy with corticosteroids administered orally or parenterally are well-known in medical practice. However, the degree of vigilance is lower when compartmental corticosteroids are used, and it is a widely held assumption that local glucocorticoids rarely produce adrenal insuffi ciency or exogenous Cushing syndrome. The two cases that we present here demonstrate the appearance of major adrenal suppression and Cushing exogenous syndrome after inadequate use of topical corticosteroids and, the combination of inhaled corticosteroids with nasal glucocorticoids, respectively. The following mini-review shows, from the endocrinologist point of view, the main aspects to be considered by practitioners who recommend local glucocorticoid treatments-i.e. inhaled, topical (cutaneous, oral, nasal, ophthalmic) or intraarticular-to prevent the occurrence of major endocrine syndromes that are met after corticosteroid therapy, tertiary adrenal insuffi ciency and exogenous Cushing syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
