Abstract

CONTEXT: ACTH-independent macronodular adrenal hyperplasia (AIMAH) is a rare and heterogeneous condition characterized by abnormal steroid production. Cortisol secretion can be regulated by aberrant hormone receptors. OBJECTIVE: A large series of patients with AIMAH were evaluated to provide information on the prevalence and profile of aberrant regulations, in relation with the functional status. DESIGN AND PATIENTS: Thirty-two consecutive patients with AIMAH were prospectively studied: 10 had a Cushing's syndrome (CS), and 22 had a subclinical CS (SCS). METHODS: A baseline endocrine evaluation was followed by an in vivo protocol in search of aberrant cortisol responses (seven provocative tests). An acute inhibition test with the somatostatin analog octreotide was also performed. RESULTS: At least one aberrant cortisol response was identified in 28 of 32 (87%) patients. The overall prevalence of aberrant responses was independent of the functional status. Responses to the upright posture and to metoclopramide were frequently observed (67 and 56% respectively). A glucagon response was frequently observed in the SCS group (58%). A cortisol inhibition by octreotide was specifically found in the three CS patients who positively responded to the mixed meal, and was observed also in 12 of 13 (92%) patients with SCS. CONCLUSIONS: Cortisol responses indicative of aberrant receptor expression were highly prevalent in AIMAH. Thorough phenotyping of AIMAH may help uncover the underlying pathophysiology.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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).”

  • Somatostatin analogs have been used to control food-dependent cortisol hypersecretion due to aberrant glucose-dependent insulinotropic peptide receptors; propranolol has been proposed in adrenal hypercortisolism and leuprolide acetate in LH-dependent Cushing's syndrome.

    “Indeed, somatostatin analogs have been used to control food-dependent cortisol hypersecretion due to the presence of aberrant glucose-dependent insulinotropic peptide receptors (100, 101); propranolol has been proposed in patients with adrenal hypercortisolism (102) and leuprolide acetate in LH-dependent Cushing's syndrome (103).”

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.
