Abstract

CONTEXT: Mild autonomous cortisol secretion (MACS) is diagnosed based on postdexamethasone cortisol >1.8 µg/dL. Scarce evidence exists on steroid circadian secretion and steroid metabolome in MACS. OBJECTIVE: To characterize 24-hour (h) urine steroid metabolome in patients with MACS and determine circadian differences in urine steroid profiling and cortisol concentrations in patients with MACS vs referent subjects. METHODS: Cross-sectional study, 2018-2023, at a referral center. Patients with MACS and age-, sex-, body mass index-, and menopausal status-matched referent subjects were included. Urine was collected over a 24 hour period as separate daytime and nighttime collections. High-resolution mass spectrometry assay was used to measure 25 steroids. A subgroup of patients and referent subjects was admitted for serum measurements of free and total cortisol every 2 hours. Outcomes were steroids, steroid sums, and ratios. RESULTS: Patients with MACS (n = 72) had lower µg/24 hour median androgens (2084 vs 3283, P < .001), higher glucocorticoids (15 754 vs 12936, P < .001), and higher glucocorticoid/androgen ratio (8.7 vs 3.9, P < .001) than referent subjects. Patients also had lower steroid day/night ratios than referent subjects, reflecting a higher relative nocturnal steroid production in MACS. In a subgroup of 12 patients with MACS and 10 referent subjects, the 24-hour areas under the curve for total and free serum cortisol were similar. However, evening mean total (5.3 vs 4.0 µg/dL, P = .056) and free (0.2 vs 0.1 µg/dL, P = .035) cortisol was higher in patients vs referent subjects. CONCLUSION: Patients with MACS demonstrate an abnormal urine steroid metabolome, with a high glucocorticoid to androgen ratio, and a higher nocturnal steroid production.

  • The use of multiple samples from blood, saliva, or subcutaneous tissue can construct a dynamic cortisol profile that offers more detailed insight into the circadian rhythm of cortisol secretion.

    “The use of multiple samples—from blood, saliva, or subcutaneous tissue—can construct a dynamic cortisol profile that offers more detailed insight into the circadian rhythm of cortisol secretion (30, 88, 94).”
  • Patients with mild CS or MACS may present with normal total 24-hour urinary cortisol production but have a disrupted cortisol circadian rhythm, often characterized by excess cortisol secretion during bedtime hours, as detected by an uncontrolled LNSC measurement.

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.
