Iatrogenic Cushing’s Syndrome and the Hidden Ingredient of Artri King

Cushing's syndrome is a rare disorder caused by prolonged exposure to glucocorticoids, either from endogenous overproduction or exogenous sources, with exogenous steroid use being the most common etiology. Clinical manifestations may include moon facies, abdominal striae, easy bruising, muscle weakness, and complications such as osteoporosis and fragility fractures. Many remedies and supplements marketed for inflammatory conditions are sold online or over the counter, and some may contain hidden or undisclosed steroids that can lead to hypercortisolism. We present a case of a 52-year-old man with osteoporosis who sustained fragility fractures and became wheelchair-bound due to progressive lower extremity weakness. Evaluation demonstrated suppression of the hypothalamic-pituitary-adrenal axis, with undetectable salivary and urinary cortisol levels. Further investigation revealed long-term use of Artri King, a supplement for musculoskeletal pain that contains undisclosed glucocorticoids. This case highlights the risk of unregulated supplements causing iatrogenic Cushing's syndrome and its associated complications.
