Drug induced iatrogenic Cushing’s syndrome

Abstract

Drug-induced (iatrogenic) Cushing's syndrome results from excessive or prolonged exposure to glucocorticoids, commonly prescribed for autoimmune, inflammatory, and hematological disorders due to their anti-inflammatory, immunosuppressive, and proapoptotic effects. Despite their therapeutic benefits, these medications can lead to a range of multisystemic symptoms mirroring those of endogenous Cushing’s syndrome. This review aims to elucidate the causes, clinical presentation, diagnosis, and management of iatrogenic Cushing's syndrome, emphasizing awareness of medications that can trigger its onset. The following review covers cortisol physiology, Cushing's syndrome etiology and subtypes, hypercortisolism complications and prognosis, and strategies for glucocorticoid withdrawal. This article synthesizes key findings and recommendations, highlighting challenges and controversies in the diagnosis and treatment of iatrogenic Cushing's syndrome.
