Abstract
OBJECTIVE The renin-angiotensin-aldosterone system (RAAS) plays a relevant role in regulating blood pressure and thus maintaining cardiovascular homeostasis. Although it was recently shown that RAAS parameters are responsive to acute psychosocial stress, the psychobiological determinants of the acute stress-induced RAAS activation have not yet been investigated. In a randomized placebo-controlled design, we investigated potential psychological and physiological determinants of the RAAS response and underlying mechanisms. METHODS Fifty-seven young healthy male participants underwent either an acute standardized psychosocial stress test or a nonstress placebo task. We measured aldosterone in plasma and saliva, as well as renin, and the stress-reactive endocrine measures adrenocorticotropic hormone (ACTH), epinephrine, and norepinephrine in plasma at rest, immediately after the task and several times up to 3 hours thereafter. Moreover, we assessed stress-reactive psychological (anticipatory cognitive stress appraisal, mood, physical discomfort) and basal demographic-physiological measures (age, body mass index, blood pressure). RESULTS Acute psychosocial stress elicited changes in all assessed endocrine (p values ≤ .028, ηp2 values ≥ 0.07) and stress-reactive psychological measures (p values ≤ .003, ηp2 values ≥ 0.15). The basal parameter body mass index, the stress-reactive endocrine parameters ACTH and norepinephrine, and the psychological parameter anticipatory stress appraisal were identified as determinants of higher RAAS parameter reactivity to acute psychosocial stress. The association between anticipatory cognitive stress appraisal and plasma RAAS measures was fully mediated by ACTH increases (p values ≤ .044, ηp2 values ≥ 0.05). CONCLUSIONS Cognitive stress appraisal processes seem to modulate RAAS stress reactivity. This points to potential clinical implications for psychoeducative therapeutical interventions targeting stress appraisal processes to reduce endocrine stress reactivity.

Abstract
Stress is a ubiquitous experience that can be adaptive or maladaptive. Physiological stress regulation, or allostasis, can be disrupted at any point along the regulatory pathway resulting in adverse effects for the individual. Children with cancer exhibit significant changes to these pathways in line with stress dysregulation and long-term effects similar to those observed in other early-life stress populations, which are thought to be, in part, a result of cytotoxic cancer treatments. Children with cancer may have disruption to several steps in the stress-regulatory pathway including cognitive-affective function, neurological disruption to stress regulatory brain regions, altered adrenal and endocrine function, and disrupted tissue integrity, as well as lower engagement in positive coping behaviours such as physical activity and pro-social habits. To date, there has been minimal study of stress reactivity patterns in childhood illness populations. Nor has the role of stress regulation in long-term health and function been elucidated. We conclude that consideration of stress regulation in childhood cancer may be crucial in understanding and treating the disease.

Abstract
Essential hypertension is a pivotal risk factor for the development of cardiovascular disease (CVD). Hypertensives exhibit greater stress-induced responses in various physiological systems considered to contribute to CVD progression. Whether this stress hyperreactivity extends to the adrenal hormone aldosterone has not yet been investigated in essential hypertension. Here, we investigated reactivity of plasma aldosterone to acute psychosocial stress induction in hypertensive and normotensive men. 21 hypertensive men and 25 normotensive controls underwent the standardized Trier-Social-Stress-Test (TSST). We repeatedly assessed plasma aldosterone before and up to 1 h after TSST cessation. Acute psychosocial stress induced significantly greater increases in hypertensives as compared to normotensives (F(3.60, 158.50) = 3.75; p = .008, f = 0.29). Our findings suggest stress-induced hyperreactivity of aldosterone in essential hypertension. Potential implications for stress-related cardiovascular risk remain to be elucidated.

Covariation of psychobiological stress regulation with valence and quantity of social interactions in everyday life: disentangling intra- and interindividual sources of variation. J Neural Transm (Vienna) 2021; 128:1381-1395. [PMID: 34181094 PMCID: PMC8423684 DOI: 10.1007/s00702-021-02359-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 05/27/2021] [Indexed: 12/20/2022]
Abstract
While the overall effects of social relationships on stress and health have extensively been described, it remains unclear how the experience of social interactions covaries with the activity of psychobiological stress in everyday life. We hypothesized that the valence as well as quantitative characteristics of social interactions in everyday life would attenuate psychobiological stress. Sixty healthy participants provided data for the analyses. Using an ecological momentary assessment design, participants received 6 prompts on their smartphone for 4 days. At each prompt, they reported on social interactions since the last prompt (any occurrence, frequency, duration, quality, and perceived social support), current subjective stress, and provided one saliva sample for the analyses of cortisol (sCort) and alpha-amylase (sAA). Experiencing any contact within days as well as higher daily levels of contact quality and perceived social support were associated with reduced levels of sCort. Furthermore, on a daily level, experiencing at least one contact in-between prompts more often as well as having more contacts on average attenuated the sAA output. Perceived social support and contact quality as well as higher daily contact durations were associated with lower subjective stress. For sCort, daily levels of stress moderated the effects of experiencing any contact within days while daily perceived social support moderated the effects of subjective stress. For sAA, experiencing at least one contact in-between prompts more often on a daily level moderated the effects of subjective stress. There were no between-person effects throughout all analyses. The results show ecologically valid evidence for direct attenuating effects of social interactions on psychobiological stress as well as for the stress-buffering hypothesis in everyday life. Increasing the quantity and improving the valence of social interactions on an intrapersonal level can possibly reduce psychobiological stress and prevent its consequences.

Abstract
Objective. Individual stress tests characterized by social evaluative threat and uncontrollability are known to elicit strong neuroendocrine responses. We tested whether a psychosocial stressor submitted to a larger group of participants (up to 60) may elicit comparable stress responses.Methods. A total of 59 adult subjects (33 women, 26 men) participated in the study, whereas 24 of them suffered from allergy and 35 were healthy. The stress test consisted of a distraction stress task followed by a speech task, in which the participants were randomly subjected to questions related to a topic that they had to prepare as well as arithmetic questions in front of their peers and a committee that responded in standardized and non-supporting manner. State and trait anxiety inventory (STAI) for anxiety state was administrated before and after the test and salivary samples taking. The test was repeated after five months.Results. The results showed that the shared psychosocial stress application in a larger group of subjects was prosperous. The larger group test (LGST) resulted in an enhanced subjectively experienced stress and an intensive sympathetic nervous system activation, reflected by elevated salivary alpha-amylase activity and the heart rate. The cortisol increment after exposure to the stress test was not significant. Repeated exposure to the test failed to reproduce the original stress responses with exception of the heart rate rise.Conclusions. In a larger group of subjects, the psychosocial stress test did elicit stress responses similar to the individual stress tests. Our data indicate that the above-mentioned stress test is apparently not an appropriate approach for the repeated use.

Abstract
Patients with atopy were found to exhibit blunted cortisol responses to acute stress stimuli. The aim of this study was to test the hypothesis that cumulative cortisol concentrations in the hair of patients with atopy are lower than in healthy subjects when related to their perceived stress experience. The sample consisted of 31 participants. The most proximal 3 cm of hair (as close to the scalp as possible), reflecting the cumulative cortisol secretion during the previous 3 months, was used for the analysis. Only in 20 subjects (9 patients with atopy and 11 healthy controls), there was a sufficient amount of hair for precise analysis using a new methodology. The results showed lower hair cortisol concentrations in patients with atopy compared to those in controls. The perceived stress scores in patients with atopy and healthy controls were not statistically different. The cortisol concentration/perceived stress score ratios were lower in patients with atopy compared to those in controls. No statistically significant correlation between hair cortisol and long-term experienced stress assessed via perceived stress scale was observed. In conclusion, the cumulative cortisol secretion in the hair of atopic patients is lower than would be expected according to their subjective scores of perceived stress. Most importantly, the previously lower stress hormone increase found in acute stress situations and in children now was confirmed in adult patients with chronic stress load.

Abstract
Several endocrine glands produce steroid hormones. Thanks to the work of chemists and biochemists, the main synthetic as well as metabolic pathways of steroid hormones were included in the textbooks more than 50 years ago and the classical endocrine gland functions were identified. Later on, evidence of steroid hormone effects beyond the classical endocrine gland function has been accumulating. Testosterone was shown to participate in the stress response and may influence coping with stressors. We have shown a decrease in testosterone concentrations in saliva in children undergoing a school exam compared to values on a non-exam school day. Testosterone has been associated with different cognitive functions in both adults and children. Circulating testosterone has been linked to negative symptoms of schizophrenia. Aldosterone is acting via mineralocorticoid receptors, which are thought to be fully occupied by glucocorticoids in the brain. Until now, an action of aldosterone in the brain has not been considered at all, because the enzyme 11-beta-hydroxysteroid dehydrogenase type 2, which would enable aldosterone to bind to receptors is absent in most of the brain areas. We have brought evidence that aldosterone can act in the brain and produce anxiogenic and depressogenic effects. To facilitate the translation of animal findings into clinical research, we have developed methodology for measurement of salivary aldosterone and obtained first data on a relationship between salivary aldosterone and trait anxiety. We have shown that salivary aldosterone concentrations reflect treatment outcome in patients with major depressive disorder.

Abstract
CONTEXT The renin-angiotensin-aldosterone system (RAAS) plays an important role in cardiovascular homeostasis and its dysfunction relates to negative health consequences. Acute psychosocial stress seems to activate the RAAS in humans, but stress kinetics and interrelations of RAAS parameters compared with a nonstress control group remain inconclusive. OBJECTIVE We systematically investigated in a randomized placebo-controlled design stress kinetics and interrelations of the reactivity of RAAS parameters measured in plasma and saliva to standardized acute psychosocial stress induction. METHODS 58 healthy young men were assigned to either a stress or a placebo control group. The stress group underwent the Trier Social Stress Test (TSST), while the control group underwent the placebo TSST. We repeatedly assessed plasma renin, and plasma and salivary aldosterone before and up to 3 hours after stress/placebo. We simultaneously assessed salivary cortisol to validate successful stress induction and to test for interrelations. RESULTS Acute psychosocial stress induced significant increases in all endocrine measures compared with placebo-stress (all P ≤ .041). Highest renin levels were observed 1 minute after stress, and highest aldosterone and cortisol levels 10 and 20 minutes after stress, with salivary aldosterone starting earlier at 1 minute after stress. Renin completed recovery at 10 minutes, cortisol at 60 minutes, salivary aldosterone at 90 minutes, and plasma aldosterone at 180 minutes after stress. Stress increase scores of all endocrine measures related to each other, as did renin and cortisol areas under the curve with respect to increase (AUCi) and salivary and plasma aldosterone AUCi (all P ≤ .047). CONCLUSIONS Our findings suggest that in humans acute psychosocial stress induces a differential and interrelated RAAS parameter activation pattern. Potential implications for stress-related cardiovascular risk remain to be elucidated.

Abstract
BACKGROUND/OBJECTIVE Cortisol is thought to be involved in the pathophysiology of affective disorders. Less attention has been given to other neuroendocrine factors. The aim of the present study was to test the hypothesis that adrenocortical steroids aldosterone and cortisol show different dynamic changes in the course of clinical depression with the assumption that aldosterone is a state marker of depression. METHODS A total of 78 adult subjects (39 patients with depressive disorder and 39 healthy controls) participated in a prospective non-interventional clinical study. Patients were investigated at the time of an acute episode and 6 months after reaching remission. The clinical and personal characteristics, and morning and evening salivary concentrations of aldosterone and cortisol were evaluated. RESULTS Patients with an acute depressive episode exhibited higher evening aldosterone and lower morning cortisol concentrations compared to healthy subjects. In these patients, both hormone concentrations showed flatter morning to evening slopes. Salivary aldosterone, but not cortisol concentrations, were lower in patients 6 months after reaching remission compared to those in the acute state. Similarly, 6 months of remission resulted in a steeper morning to evening slope of salivary aldosterone compared to the acute state. The cortisol rhythm remained dysregulated. A significant negative correlation between trait anxiety scores and morning cortisol concentrations in patients at 6 months of clinical remission was observed. CONCLUSION Diurnal changes in salivary aldosterone concentrations appear to be a state marker, whilst those of cortisol a trait marker of depression.

Abstract
Glucocorticoid signaling is fundamental in healthy stress coping and in the pathophysiology of stress-related diseases, such as post-traumatic stress disorder (PTSD). Glucocorticoids are metabolized by cytochrome P450 (CYP) as well as 11-β-hydroxysteroid dehydrogenase type 1 (11βHSD1) and 2 (11βHSD2). Acute stress-induced increase in glucocorticoid concentrations stimulates the expression of several CYP sub-types. CYP is primarily responsible for glucocorticoid metabolism and its increased activity can result in decreased circulating glucocorticoids in response to repeated stress stimuli. In addition, repeated stress-induced glucocorticoid release can promote 11βHSD1 activation and 11βHSD2 inhibition, and the 11βHSD2 suppression can lead to apparent mineralocorticoid excess. The activation of CYP and 11βHSD1 and the suppression of 11βHSD2 may at least partly contribute to development of the blunted glucocorticoid response to stressors characteristic in high trait anxiety, PTSD, and other stress-related disorders. Glucocorticoids and glucocorticoid-metabolizing enzymes interact closely with other biomolecules such as inflammatory cytokines, monoamines, and some monoamine-metabolizing enzymes, namely the monoamine oxidase type A (MAO-A) and B (MAO-B). Glucocorticoids boost MAO activity and this decreases monoamine levels and induces oxidative tissue damage which then activates inflammatory cytokines. The inflammatory cytokines suppress CYP expression and activity. This dynamic cross-talk between glucocorticoids, monoamines, and their metabolizing enzymes could be a critical factor in the pathophysiology of stress-related disorders.Lay summaryGlucocorticoids, which are produced and released under the control by brain regulatory centers, are fundamental in the stress response. This review emphasizes the importance of glucocorticoid metabolism and particularly the interaction between the brain and the liver as the major metabolic organ in the body. The activity of enzymes involved in glucocorticoid metabolism is proposed to play not only an important role in positive, healthy glucocorticoid effects, but also to contribute to the development and course of stress-related diseases.

Abstract
It has been documented that cortisol release in response to acute stressors is reduced in patients with atopic dermatitis, allergic rhinitis, and other atopic diseases compared to that in healthy subjects. We aimed to test the hypothesis that atopic patients exert reduced salivary cortisol awakening response (CAR) in comparison with healthy subjects. The hypothesis was tested on a stressful and a relax day selected subjectively. Moreover, we evaluated the impact of trait anxiety. The sample consisted of 60 subjects, out of which 28 were patients with atopy and 32 healthy volunteers of both sexes. Saliva samples were collected in the morning to evaluate CAR as well as in the early afternoon and evening to look at cortisol concentrations during the rest of the day. The results showed reduced CAR in atopic patients compared to that in healthy subjects. This effect was modulated by sex with a significant difference observed in males. While CAR was reduced, atopic patients had unchanged cortisol concentrations throughout the day. The evening cortisol was even higher in atopic patients. If the subjects were stratified according to the trait anxiety, no significant differences in CAR between high and low anxiety were observed. No differences in cortisol variables including CAR were observed between the stressful and relax day. In conclusion, this study presents evidence on reduced CAR suggesting an insufficient HPA axis reactivity in atopy. Furthermore, the data in atopic patients demonstrate that reduced HPA axis reactivity does not necessarily mean lower cortisol concentrations throughout the day. This might be of relevance to immune system function and the course of the disease.

Abstract
The impact of sex and the menstrual cycle phase on the autonomic response to psychosocial stress remains controversial. This study explored autonomic nervous system activity through salivary alpha-amylase, heart rate, and heart rate variability responses to the Trier Social Stress Test (TSST) in healthy young people. The sample was composed of 25 men, 26 women in the luteal phase, and 25 women in the follicular phase, from 18 to 25 years of age. Participants were exposed to the TSST or a control condition. The results indicate that women in their follicular phase showed a blunted alpha-amylase response to stress compared to men and women in the luteal phase. In addition, men showed higher sympatho-vagal activity in the stress condition compared to the two groups of women. These results confirm that sex and the menstrual cycle phase are potential modulators of autonomic nervous system reactivity to psychosocial stress.

Mineralocorticoid receptor-related markers and outcome of major depression: focus on blood pressure and electrolytes. Int Clin Psychopharmacol 2018; 33:224-228.

Abstract
A close association between vegetative regulation and affect is common knowledge. Recently, the role of aldosterone and the activity of its receptor [mineralocorticoid receptor (MR)] in the clinical outcome for treatment with standard antidepressants has been shown including low systolic blood pressure and a low concentration of plasma sodium (Na), both of which appear to be related to therapy resistance to standard antidepressants. We carried out a retrospective analysis of a double-blind placebo-controlled trial of St John's wort extract LI160 in 247 outpatients with major depression. The study did not show a difference between the treatment groups; therefore, a pooled dataset of the 6-week completer population of the trial was analyzed. The focus was on the moderating effect of blood pressure and electrolytes on clinical outcome (relative change in Montgomery-Asberg Depression Rating Scale). Low Na/K ratio and high K at screening predicted worse outcome after 6 weeks as measures with the Montgomery-Asberg Depression Rating Scale (P<0.01). Systolic blood pressure at the same time point did not influence the treatment outcome. In conclusion, signs of reduced peripheral MR sensitivity, as reflected by a lower plasma Na/K ratio and/or higher K concentration, predict worse outcome. This is in line with our recent data as well as neuroendocrine findings. The data indicate that widely collected biomarkers, which are related to MR activity, may be useful to identify patients, who are at risk of nonresponse to antidepressant treatment.

Abstract
OBJECTIVE Occupational/mental stressors, which may be evaluated with measurements of salivary cortisol concentrations, affect the endothelial function and has implications on cardiovascular health. Nitric oxide (NO) is known to have an important role in cardiac function and may also be assessed in the saliva, but its participation in physiological responses to hypothalamic-pituitary-adrenal (HPA) axis stimulation is still not completely understood. The aim of the present study was to test the hypothesis that salivary NO (as nitrite) and cortisol concentrations in school teachers vary throughout the academic year. METHODS Saliva samples were collected from 13 teachers distributed across five secondary schools. The samples were collected at 6:30 a.m., 11:30 a.m., and 5:30 p.m. in the months of March, July, and December. Salivary cortisol levels were measured by enzyme immunoassay (EIA), and salivary NO concentration was determined by the quantification of nitrite. The area under the curve in relation to ground (AUC) was calculated to assess the cortisol and nitrite concentrations throughout the day. RESULTS No significant changes were observed in cortisol or nitrite concentrations across the three periods of the school year, while cortisol and nitrite levels showed a low positive and significant correlation (r=0.3455, p=0.0336). CONCLUSION The results suggest that changes in salivary cortisol levels are accompanied by changes in salivary nitrite levels. This is the first time that such association has been demonstrated. These results encourage further studies aimed to confirm the importance of salivary NO measurement in relation to occupational stress and cardiovascular health.

Abstract
Exposure to stress activates both the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). A growing body of research points to the contribution of sex hormones (testosterone, estrogen, and progesterone), the end products of the hypothalamus-pituitary-gonadal (HPG) axis, in modulating stress reactivity. The present study aimed at investigating the potential modulating role of sex hormones on HPA and SNS reactivity to psychosocial stress. The reactivity, induced by the Trier Social Stress Test, was analyzed by measuring the levels of cortisol and alpha-amylase (markers for SNS activity) in four saliva samples each of 21 men and 37 women (17 not using oral contraceptives and in their luteal phase, and 20 women using oral contraceptives). In addition, basal sex hormones were sampled prior to the psychosocial stress exposure. Results revealed that controlling for testosterone, estrogen, and progesterone diminished the impact of stress on cortisol reactivity and on alpha-amylase reactivity. Moreover, controlling for sex hormones also diminished the differential pattern of cortisol reactivity in each experimental group among responders. Furthermore, correlation analyses revealed differences between groups in the association between sex hormones and alpha-amylase. The present findings indicate a modulatory role for sex hormones in HPA and SNS reactivity and emphasize the need for control of sex hormone fluctuations when examining cortisol and alpha-amylase reactivity to stress.

Abstract
PURPOSE We examined the effects of a humor intervention on the physiological, physical, and psychological responses of school-aged children with atopic dermatitis. DESIGN AND METHODS This quasi-experimental study used a nonequivalent control group and a pre- and post-test design. Forty-five schoolchildren participated. RESULTS Children in the experimental group (n=26) received a humor intervention and reported significant differences in physiological response, which was evidenced by heightened salivary immunoglobulin A levels as compared to the control group (n=19). Additionally, the psychological response of the experimental group was significantly different from that of the control group as evidenced by decreased stress levels. CONCLUSION Humor intervention may be an effective nursing intervention for children with atopic dermatitis.

Abstract
This study adopted a person-centered approach to identify preadolescent salivary cortisol (sC) and alpha-amylase (sAA) co-activation response patterns and examine links to behavioral functioning and coping. Children (N = 151, 51.7% male) were exposed to the Trier Social Stress Test (TSST) and one of two randomly-assigned, post-TSST coping conditions: distraction or avoidance. Multi-trajectory modeling yielded four child subgroups. Child internalizing and externalizing positively predicted High sC-High sAA relative to Low sC-Low sAA and Low sC-High sAA relative to High sC-Low sAA subgroup membership, respectively. Low sC-Low sAA children demonstrated more efficient sC recovery when primed with distraction and more protracted sC recovery when primed with avoidance. For High sC-High sAA, internalizing children, the opposite was true. Findings illustrate adjustment-linked variability in preadolescent sC-sAA co-activation response patterns that further articulates for whom effortful coping works to effectively manage stressor-induced neuroendocrine activation.

Abstract
At the time of school-age, the most frequent stress stimuli are related to school environment and educational process. Anxiety may play a big role in coping with stressful situations associated with school load. To approach this issue, we performed a real-life study at school during the classwork. The sample consisted of 36 healthy children aged 10 years, which were divided to low and high trait anxiety group based on the median value of the anxiety score. The investigations were carried out in the classroom during a stress condition (final exams) and non-stress condition (without any exam). In the whole sample, the condition with exam was associated with higher cortisol and lower testosterone concentrations in saliva compared to the condition without exam. The activity of salivary alpha-amylase increased at the end of the exam. Anxious children showed higher concentrations of aldosterone and lower activity of alpha-amylase compared to children with low trait anxiety. Cortisol levels were higher in anxious children in the first morning samples before starting the lessons. Children with high and low trait anxiety did not differ in extraversion, neuroticism, as well as non-verbal intelligence and school success. Thus, the anxious children at school showed a more rapid decrease of anticipatory stress-induced cortisol concentrations, higher aldosterone levels, and lower alpha-amylase activities compared to non-anxious children. These changes, particularly high concentrations of aldosterone in children with high trait anxiety, may have an impact on their psychophysiological development.

Abstract
To evaluate the interactions between polyfluoroalkyl substances (PFASs) and reproductive hormones and associated asthma, a total of 231 asthmatic and 225 non-asthmatic adolescents were selected from northern Taiwan in the Genetic and Biomarkers study for Childhood Asthma from 2009–2010. The interaction between PFASs and reproductive hormones on asthma was analyzed with a two-level binary logistic regression model. The results showed that, among asthmatics, PFASs were positively associated with estradiol levels and negatively associated with testosterone levels. However, only significant association was identified for PFNA and estradiol in control group. After controlling for hormone levels, associations between PFAS exposure and asthma were consistently stronger among children with higher than lower estradiol, with odds ratios (OR) for asthma ranging from 1.25 for PFOS (95% Confidence Interval [CI]: 0.90, 1.72) to 4.01 for PFDA (95% CI: 1.46, 11.06) among boys and 1.25 for PFOS (95% CI: 0.84, 1.86) to 4.16 for PFNA (95% CI: 1.36, 12.73) among girls. Notably, the interactions between estradiol and PFASs were significant for PFOS (p = 0.026) and PFNA (p = 0.043) among girls. However, testosterone significantly attenuated the association between PFOS and asthma across sex. In conclusions, our findings suggested that reproductive hormones amplify the association between PFASs and asthma among adolescents.
