Cortisol, 11β-Hydroxysteroid Dehydrogenases, and Hypertension
Bibliographic record
Abstract
Hypersecretion of cortisol is associated with hypertension. In addition, an abnormal cortisol metabolism may play a role in the pathogenesis of hypertension. The 11beta-hydroxysteroid dehydrogenase (11beta-HSD) isozymes catalyze interconversion of cortisol and cortisone and play an important role in the regulation of the effects of cortisol. Activity of 11beta-HSD type 2, converting active cortisol in inactive cortisone, is crucial in preventing access of cortisol to the renal mineralocorticoid receptors (MRs). Decreased activity of this isozyme in the kidney, either congenitally in Apparent Mineralocorticoid Excess syndrome or acquired following licorice consumption, allows cortisol access to the MRs, resulting in hypokalemic hypertension. In normotensive subjects, an association has been demonstrated between blood pressure increase on a high-salt diet and a mild decrease of renal 11beta-HSD2 activity. In ectopic adrenocorticotropic hormone (ACTH), plasma cortisol levels are very high, resulting in mineralocorticoid hypertension caused by saturation of the available renal 11beta-HSD2 capacity. Activity of the 11beta-HSDs has also been demonstrated in many extrarenal sites. Several studies have demonstrated extrarenal effects of cortisol on blood pressure, as well as a possible role for altered extrarenal 11beta-HSD activities in the pathogenesis of hypertension. More studies are needed to clarify the role of 11beta-HSDs in the pathogenesis of hypertension.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
