Aggressiveness of therapy depends on the clinical status of the patient and the nature of the insufficiency (glucocorticoid, mineralocorticoid, or both). Many dogs and cats with primary adrenal insufficiency are presented in Addisonian crisis and require immediate, aggressive therapy. In contrast, secondary insufficiency often has a chronic course.
The size of the adrenal glands can be useful in diagnosis, studies have found that the size of the adrenal gland in diabetic cats without hypersomatotropism does not differ significantly from non-diabetic cats; [11] [12] [1] however adrenomegaly is not pathognomonic to hypersomatotropism and can occur with other conditions in cats such as ...
Insulin tolerance testing is widely regarded as the gold standard for assessing the entire hypothalamic-pituitary-adrenal axis. [2] A high-dose ACTH stimulation test directly evaluates the adrenal secretory reserve, which can be compromised not only in primary adrenal insufficiency but also in long-term ACTH deficiency. [2]
Primary adrenal insufficiency predisposes to higher risk of death, mostly due to infection, cardiovascular disease, and adrenal crisis. [2] Delayed diagnosis can impair quality of life, and lack of treatment brings high mortality. [2] However, with proper diagnosis, monitoring, and treatment, people with adrenal insufficiency can live normally. [3]
An "adrenal crisis" or "Addisonian crisis" is a constellation of symptoms that indicates severe adrenal insufficiency. This may be the result of either previously undiagnosed Addison's disease, a disease process suddenly affecting adrenal function (such as adrenal hemorrhage ), or an intercurrent problem (e.g., infection, trauma) in someone ...
Addison's disease, or primary adrenal insufficiency, is an uncommon chronic illness characterized by insufficient production of cortisol and aldosterone by the adrenal glands. [17] Chronic primary adrenal insufficiency is typically characterized by an extended period of malaise, fatigue, anorexia, weight loss, joint and back pain, and skin ...
