Knowra Glucocorticoid withdrawal Glucocorticoid withdrawal Glucocorticoid withdrawal is the return of symptoms or development of adrenal insufficiency after glucocorticoids are reduced or stopped following sustained treatment. It can reflect disease relapse, withdrawal syndrome, or suppression of the body's cortisol production.
Hypothalamic–pituitary–adrenal axis : The hormonal system linking the hypothalamus, pituitary gland, and adrenal glands to regulate cortisol production. Sustained glucocorticoid exposure suppresses this system, limiting the body's cortisol response after treatment stops.
Glucocorticoid taper : A planned, usually gradual reduction in glucocorticoid dose rather than abrupt cessation. Tapering manages both the risk of disease recurrence and the body's need to resume cortisol production.
Adrenal crisis : A life-threatening acute state of severe cortisol deficiency, often involving low blood pressure and metabolic disturbances. It is the dangerous extreme of adrenal insufficiency that may follow withdrawal in a vulnerable patient.
Glucocorticoid : A class of steroid hormones and medicines that regulate metabolism, stress responses, and inflammation. Withdrawal follows reduction of medicines that mimic the body's glucocorticoid hormones.
Adrenal insufficiency : A state in which the adrenal glands do not produce enough cortisol, sometimes also aldosterone. Suppression of cortisol production can make dose reduction or cessation expose inadequate adrenal function.
Adrenal function testing : Tests, including morning cortisol measurement and stimulation testing, used to assess adrenal cortisol production. Testing can help determine whether persistent symptoms during tapering reflect inadequate adrenal function.
Glucocorticoid withdrawal syndrome : A cluster of symptoms following glucocorticoid reduction despite doses that may still provide adequate cortisol replacement. It differs from proven adrenal insufficiency because symptoms can occur without inadequate cortisol levels.
Adrenocorticotropic hormone : A pituitary hormone that stimulates the adrenal cortex to produce cortisol. Glucocorticoid feedback can lower this signal, reducing adrenal stimulation during treatment.
Glucocorticoid-induced adrenal insufficiency : Adrenal insufficiency caused by suppression of the hypothalamic–pituitary–adrenal axis during glucocorticoid treatment. This is the specific endocrine complication that can emerge when treatment no longer supplies enough glucocorticoid.
Cosyntropin stimulation test : A test of adrenal cortisol reserve using synthetic adrenocorticotropic hormone, or cosyntropin. It can assess adrenal responsiveness when recovery after prolonged glucocorticoid exposure is uncertain.
