Apparent mineralocorticoid excess syndromes

Shimojo, M., Stewart, Paul M.·1995·Journal of Endocrinological Investigation

Abstract

Apparent mineralocorticoid excess (AME) is a syndrome attributable to congenital deficiency of the enzyme 11 beta-dehydrogenase (11 beta-OHSD) which converts active glucocorticoid cortisol to inactive cortisone. When 11 beta-OHSD activity is impaired, cortisol acts as a potent mineralocorticoid and causes hypertension and hypokalemia with a suppression of the renin-angiotensin-aldosterone system. The increased ratio of urinary cortisol/cortisone metabolites and a prolonged half-life of cortisol are useful for the diagnosis. Dexamethasone and/or potassium sparing diuretics have been used for medication of AME. Licorice ingestion induces a mineralocorticoid excess state, and it seems that this is the result of acquired inhibition of 11 beta-DH by glycyrrhetinic acid. The existence of a second 11 beta-OHSD isoform has been suggested strongly for a long time, and recently, a human 11 beta-OHSD 2 cDNA has been isolated. It appears that 11 beta-OHSD 2 conveys specificity upon the renal MR, and a defect in its activity seems likely to account for the phenotype of AME.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
