Aldosteronism15
Although initially considered a rarity, primary aldosteronism now is considered one of the more common causes of secondary hypertension (HTN). (medscape.com)
Conn syndrome, as originally described, refers specifically to primary aldosteronism due to the presence of an adrenal aldosteronoma (aldosterone-secreting benign adrenal neoplasm). (medscape.com)
Based on older data, it was originally estimated that primary aldosteronism accounted for less than 1% of all patients with HTN. (medscape.com)
Although primary aldosteronism is still a considerable diagnostic challenge, recognizing the condition is critical because primary aldosteronism-associated HTN can often be cured (or at least optimally controlled) with the proper surgical or medical intervention. (medscape.com)
The diagnosis is generally 3-tiered, involving an initial screening, a confirmation of the diagnosis, and a determination of the specific subtype of primary aldosteronism. (medscape.com)
These reports suggested that IAH may be responsible for as many as 75% of primary aldosteronism cases. (medscape.com)
Moreover, reports have described a rare syndrome of primary aldosteronism characterized by histologic features intermediate between adrenal adenoma and adrenal hyperplasia, which often is unilaterally localized (also referred to in earlier literature as "intermediate aldosteronism") (see Etiology). (medscape.com)
Clinically, the distinction between the 2 major causes of primary aldosteronism is vital because the treatment of choice for each is markedly different. (medscape.com)

Sutherland and colleagues first described the type 1 variety of familial primary aldosteronism, glucocorticoid-remediable aldosteronism (GRA), in 1966. (medscape.com)
As diagnostic techniques have advanced, primary aldosteronism (PA) has emerged as the most common cause of secondary hypertension. (e-enm.org)
BACKGROUND: Primary aldosteronism is frequently caused by an adrenocortical aldosterone-producing adenoma (APA) carrying a somatic mutation that drives aldosterone overproduction. (bvsalud.org)
OBJECTIVE: To assess the prevalence of autonomous/possible autonomous cortisol secretion (ACS), primary aldosteronism (PA), pheochromocytoma (PHEO), and Cushing syndrome (CS) in patients with AI. (bvsalud.org)
BACKGROUND: Aldosterone-producing adenomas (APAs) are a major cause of primary aldosteronism, a condition of low-renin hypertension, in which aldosterone overproduction is usually driven by a somatic activating mutation in an ion pump or channel. (bvsalud.org)
However, they need to undergo a careful clinical and biochemical evaluation for adrenal hormone excess (pheochromocytoma, primary aldosteronism, Cushing syndrome, feminization/virilism) and the risk of malignancy. (empendium.com)
Cortisol5
Through these studies, the cyclic AMP-dependent protein kinase A signaling has been identified as a key mediator of cortisol secretion, and the mutations associated with the dysregulation of cyclic AMP - protein kinase A pathways have been implicated in the adrenocortical pathophysiology. (wikipedia.org)
We describe a case of aldosterone-producing adrenocortical adenoma (APA) associated with a probable post-operative adrenal crisis possibly due to subtle autonomous cortisol secretion. (elsevierpure.com)
Post-operative adrenocortical insufficiency should be considered in clinical management of patients with relatively large APA, even when physical signs of autonomous cortisol overproduction are not apparent. (elsevierpure.com)
Cushing syndrome is a constellation of clinical features related to either exposure to excessive levels of cortisol 4 secreted endogenously from the adrenal glands 5 (e.g., due to Cushing disease 6 , adrenal adenoma 7 , or bilateral adrenal hyperplasia) or to chronic excessive levels of exogenous glucocorticoid ("cortisol-like") medication 8 (e.g., prednisone).
