Abstract

BACKGROUND: Incidentally discovered adrenal tumours are frequently associated with subclinical autonomous cortisol hypersecretion of unknown origin. Aberrant hormone receptors have been observed in case reports of overt Cushing's syndrome. The question arises as to whether such receptors may be present in the functioning adrenal incidentaloma, which is common and might be a subclinical stage of Cushing's syndrome. PATIENTS AND METHODS: Twenty-one consecutive patients with a unilateral incidentaloma, the biochemical features of subclinical cortisol hypersecretion and/or the scintigraphic features of an autonomously functioning adrenal adenoma were investigated for plasma cortisol responses to various stimuli: upright posture, meal, combined hypothalamic-hormones, the vasopressin analogue terlipressin, glucagon, angiotensin II, the serotonin 5-HT4 agonist cisapride, and ACTH. Six normal controls were similarly investigated. All subjects were studied during 8 mg per day dexamethasone in order to avoid any ACTH-dependent variation of plasma cortisol. RESULTS: The most constant responses in adrenal incidentalomas were observed after stimulation by terlipressin (18/20 patients, 28-415% cortisol increase) and cisapride (17/21 patients, 25-364% cortisol increase). Eighteen out of 21 patients responded to several stimuli (cortisol increase >or= 25%), and all responded to at least one stimulus other than ACTH, while such responses were absent in the controls. Plasma ACTH remained suppressed in all subjects throughout the study. CONCLUSIONS: Aberrant membrane receptors detected by in vivo stimulation tests appear to be common in autonomously functioning unilateral adrenocortical adenomas. These receptors may be involved in the modulation of cortisol secretion in adrenal incidentaloma, with potential therapeutic consequences for the control of subclinical cortisol hypersecretion.

  • Aberrant receptors may be specific pharmacological targets for controlling cortisol secretion.

    “Because these aberrant receptors may be specific pharmacological targets for controlling cortisol secretion, their detection deserves particular interest and some protocols have been developed (99).”

    From Diagnosis and Treatment of Subclinical Hypercortisolism (2011) · cites this paper as [99]

  • Receptors for several ligands are abnormally expressed at the membrane of tumoral adrenocortical cells.

    “it has been shown that receptors for several ligands are abnormally expressed at the membrane of tumoral adrenocortical cells, such as those for glucose-dependent insulinotropic peptide, catecholamine, vasopressin, serotonin, angiotensin II, leptin, and LH/human chorionic gonadotropin (98 -100).”

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.
