Pituitary Adrenal Axis

In several studies lactation has been shown to be associated with a hypothalamic-pituitary-adrenal axis hyporesponsiveness to physical and psychological stressors. As it is not known whether the marked blunting of endocrine stress reactivity in women can be ascribed to suckling as a short-term effect or to lactation in general, the acute effects of suckling on the hypothalamic-pituitary-adrenal axis and the sympathetic-adrenal-medullary system responses to mental stress were investigated in lactating women. Forty-three lactating women were randomly assigned either to breast-feed or to hold their infants for a 15-min period with the onset 30 min before they were exposed to a brief psychosocial stressor (Trier Social Stress Test). Both breast-feeding and holding the infant yielded significant decreases in ACTH, total plasma cortisol, and salivary free cortisol (all P < 0.01). There were no significant differences in baseline hormone levels between the groups 1 min before the stress test. In response to stress exposure, ACTH, total plasma cortisol, salivary free cortisol, norepinephrine, and epinephrine were significantly increased in all lactating women (all P < 0.001). However, total cortisol and free cortisol responses to stress were attenuated in breast-feeding women (P = 0.001 and P = 0.067, respectively), who also showed significantly decreasing PRL levels during the stress test (P = 0.005). In addition, there was no change in plasma oxytocin or vasopressin in response to the stressor. Breast-feeding as well as holding led to decreased anxiety (P < 0.05), whereas, in contrast, stress exposure worsened mood, calmness, and anxiety in the total group (all P < 0.001). From these data we conclude that lactation in women, in contrast to that in rats, does not result in a general restraint of the hypothalamic-pituitary-adrenal axis response to a psychosocial stressor. Rather, suckling is suggested to exert a short-term suppression of the cortisol response to mental stress.

This study examined whether perceived attachment security (i.e., perceptions of caregivers as responsive, available, and open to communication during times of need) and effortful coping work in concert to buffer against uncontrollable life event effects on hypothalamic–pituitary–adrenal axis (HPA) response patterns in preadolescent boys and girls ( N = 121, mean age = 10.60 years). Children completed the Trier Social Stress Test (TSST) and were immediately thereafter exposed to one of two randomly assigned coping conditions: distraction and avoidance. Piecewise growth multilevel modeling of children’s salivary cortisol levels over the course of the experimental protocol suggested that uncontrollable life events in the year prior were associated with exaggerated cortisol reactivity, though this pattern was buffered against by children’s secure attachment beliefs. Furthermore, perceived attachment security, uncontrollable life event, and coping condition interactive effects on cortisol recovery emerged. As expected, distraction supported efficient cortisol recovery for those uncontrollable stress-exposed children with secure beliefs, and avoidance worked in this fashion for those with insecure beliefs. Findings point to perceived attachment security as a putative buffer of stress-exposed preadolescents’ HPA reactivity and possible contributor to regulatory fit, informing how specific coping skills work or backfire in supporting these children’s HPA recovery efficiency.

BackgroundHypothalamic-pituitary-adrenal axis functioning, with cortisol as its major output hormone, has been presumed to play a key role in the development of psychopathology. Predicting affective disorders from diurnal cortisol levels has been inconclusive, whereas the predictive value of stress-induced cortisol concentrations has not been studied before. The aim of this study was to predict mental disorders over a 3-year follow-up from awakening and stress-induced cortisol concentrations.MethodData were used from 561 TRAILS (TRacking Adolescents’ Individual Lives Survey) participants, a prospective cohort study of Dutch adolescents. Saliva samples were collected at awakening and half an hour later and during a social stress test at age 16. Mental disorders were assessed 3 years later with the Composite International Diagnostic Interview (CIDI).ResultsA lower cortisol awakening response (CAR) marginally significantly predicted new disorders [odds ratio (OR) 0.77, p = 0.06]. A flat recovery slope predicted disorders with a first onset after the experimental session (OR 1.27, p = 0.04). Recovery revealed smaller, non-significant ORs when predicting new onset affective or anxiety disorders, major depressive disorder, or dependence disorders in three separate models, corrected for all other new onsets.ConclusionsOur results suggest that delayed recovery and possibly reduced CAR are indicators of a more general risk status and may be part of a common pathway to psychopathology. Delayed recovery suggests that individuals at risk for mental disorders perceived the social stress test as less controllable and less predictable.

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.
