ContextIt is unknown whether the metabolic effects of the removal of an adrenal incidentaloma (AI) can be predicted by the assessment of cortisol hypersecretion before surgery.ObjectiveTo evaluate the accuracy of several criteria of hypothalamic–pituitary–adrenal axis activity in predicting the metabolic outcome after adrenalectomy.DesignRetrospective longitudinal study.PatientsIn 55 surgically treated AI patients (Group 1) before surgery and in 53 nontreated AI patients (Group 2) at the baseline, urinary free cortisol (UFC), cortisol after 1 mg overnight dexamethasone-suppression test (1 mg-DST), ACTH, and midnight serum cortisol (MSC) were measured. In Groups 1 and 2, metabolic parameters were evaluated before and 29.6±13.8 months after surgery and at the baseline and after 35.2±10.9 months respectively.Main outcome measuresThe improvement/worsening of weight, blood pressure, glucose, and cholesterol levels (endpoints) was defined by the presence of a >5% weight decrease/increase and following the European Society of Cardiology or the ATP III criteria respectively. The accuracy of UFC, 1 mg-DST, ACTH, and MSC, singularly taken or in combination, in predicting the improvement/worsening of ≥2 endpoints was calculated.ResultsThe presence of ≥2 among UFC>70 μg/24 h (193 nmol/l), ACTH<10 pg/ml (2.2 pmol/l), 1 mg-DST>3.0 μg/dl (83 nmol/l) (UFC–ACTH–DST criterion) had the best accuracy in predicting the endpoints' improvement (sensitivity (SN) 65.2%, specificity (SP) 68.8%) after surgery. In the nontreated AI patients, this criterion predicted the worsening of ≥2 endpoints (SN 55.6%, SP 82.9%).ConclusionsThe UFC–ACTH–DST criterion seems to be the best for predicting the metabolic outcome in surgically treated AI patients.

Pituitary Adrenal Axis

The hypothalamic-pituitary-adrenal axis was investigated in 15 asthmatic children treated with inhaled beclomethasone dipropionate (mean 490 µg/day) and 11 asthmatic control subjects receiving no corticosteroid therapy. Measurements of 24-h urinary free cortisol and 17 hydroxy corticosteroids, serum cortisol, response to ACTH, and the oral metyrapone test showed no significant difference between the two groups. All the patients' results were within normal limits, and carbohydrate metabolism, as shown by blood glucose and hemoglobin A1c, was not affected by beclomethasone therapy. Thus, in the above dose, inhaled beclomethasone does not cause suppression of the hypothalamic--pituitary-adrenal axis.

Inhaled corticosteroids have become an important therapeutic option in the treatment of childhood asthma. The preparations currently available for pediatric use (beclomethasone dipropionate and triamcinolone acetonide) do not, in general, cause significant hypothalamic-pituitary-adrenal axis suppression and physical signs of glucocorticoid excess have not been described with their use. We report an 8-year-old girl with asthma in whom obesity, hirsutism, and growth retardation developed during treatment with inhaled triamcinolone acetonide alone. Laboratory studies showed suppression of endogenous cortisol production but did not demonstrate suppression of the hypothalamic-pituitary-adrenal axis. Cessation of inhaled triamcinolone acetonide therapy resulted in resolution of obesity and hirsutism, resumption of normal growth, and a return to normal of serum cortisol levels and urinary 17-hydroxycorticosteroid excretion. Careful monitoring of growth velocity and (if clinically indicated) morning serum cortisol levels in asthmatic children using inhaled corticorsteroids will detect the rare instance of glucocorticoid excess resulting from systemic absorption of these drugs.

SynopsisWe measured urinary outputs of urinary-free cortisol in 28 medication-free depressed patients and 32 normal controls. Depressed patients had significantly greater urinary outputs of urinary-free cortisol than controls. Also, there were significant correlations among depressed patients, but not among controls, between urinary-free cortisol and urinary outputs of norepinephrine and its metabolite vanillylmandelic acid (VMA). These urinary data extend recent findings suggesting that dysregulation of both the hypothalamic-pituitary-adrenal axis and noradrenergic system occur together in depression.
