Abstract
OBJECTIVE Panic disorder (PD) may cause serious cardiac arrhythmias by causing electrical abnormalities. Abnormal P-wave axis (aPwa), presence of fragmented QRS (fQRS), wide frontal QRS-T angle (fQRSTa), QRS duration corrected (QRSdc) and log/ logQRS duration/RR interval (log/logQRS/RR) have been correlated with increased risk of serious supraventricular and ventricular cardiac arrhythmias in a general population. The purpose of this study was to compare these newly explored atrial and ventricular arrhythmia indicators in patients with PD and in healthy subjects. METHOD A total of 169 newly diagnosed PD patients and 128 healthy subjects were included in the study. The Panic and Agoraphobia Scale (PAS) was administered, and 12-lead electrocardiography (ECG) measurements were obtained. Electrocardiographic parameters including aPwa, fQRSTa, presence of fQRS, QRS duration corrected (QRSdc), and log/logQRS duration/RR distance (log/logQRS/RR) were compared between the two groups. RESULTS aPwa and fQRS, in addition to fQRSTa, QRSdc, and log/ logQRS/RR ratio values, were significantly increased in the PD group compared to healthy controls. Correlation analyses revealed that wider fQRSTa, number of fQRS derivation, number of total fQRS, wider QRSdc, and log/logQRS/RR ratio significantly correlated with PAS score. Logistic regression analysis demonstrated that fQRSTa and the number of total fQRS were independently associated with PD. CONCLUSION PD is associated with wider fQRSTa, QRSdc, and log/logQRS/RR in addition to the increased abnormal aPwa and presence of fQRS. These findings suggest that untreated PD patients may be susceptible to supraventricular and ventricular arrhythmia, indicating that ECG should be routinely obtained in the management of PD patients.

Abstract
Introduction: Psychological symptoms (PSs) are also seen in healthy individuals. The aim of this study is to examine some familial characteristics in the relationship between PSs and serum serotonin (5-HT) and salivary cortisol (sCTS) levels in healthy individuals.
Materials and Method: A sociodemographic data form and a psychiatric symptom screening questionnaire (SCL-90-R) were given to 320 healthy individuals (156 males, 164 females) aged between 18-65 years and without any mental illness. Blood and saliva samples were duly taken and evaluated by ELISA method. The research protocol was approved by the Ankara Keçiören Training and Research Hospital Clinic Research Ethics Committee (study number KÖTRH-CREC_11.07.2012/103). Informed consent was obtained from the participants before participating in the study. Statistical analyzes were performed with the SPSS 15.0 program. Descriptive statistical data (number, percentage, mean, standard deviation, minimum and maximum), independent sample t test, One-way ANOVA test, Kruskal Wallis H test, Mann-Whitney U test, Pearson Correlation analysis were used in the analyzes. For statistical significance, p˂.05 was accepted as significant.
Results: The highest PS levels of the participants were obsessive-compulsive symptoms (.92±.80), interpersonal sensitivity (.75±.55) and depressive symptoms (.72±.53), respectively. The general symptom index (GSI) was .61±.46. Psychotic (χ2(2)=7.021, p=.03) and phobic symptoms (χ2(2)=7.130, p=.03) in those living in a nuclear family, depression levels in those whose parents lived together (t=-2.114, p=.04) was lower. Somatization, anxiety, obsession, depression, interpersonal sensitivity, psychoticism, paranoid, thought, hostility and additional symptom levels were highest in illiterate parents. Phobic symptom levels were highest in those whose fathers were illiterate. In patients with a family history of psychiatric illness, somatization (t=2.108, p=.04), anxiety (t=2.103, p=.02), obsession (t=2.146, p=.03), depression (t=2.548, p=.01), anger-hostility (t=3.096, p=

Abstract
The hippocampus is thought to play an important role in conveying contextual information to the amygdala as the neural basis of panic disorder (PD). Previous studies have revealed functional abnormalities in the hippocampus in patients with PD compared with healthy control subjects (HC), but no study has reported volume abnormalities in the hippocampus or evaluated minute structural changes in the hippocampus in such patients. We thus investigated volume abnormalities in the subfields of the hippocampus to better understand the neurobiological basis of PD. The hippocampus was extracted from structural brain magnetic resonance images obtained from 38 patients with PD and 38 HC and then segmented into six subfields. The relative volume of each subfield was compared between the two groups. The severity of symptoms was assessed using the Panic Disorder Severity Scale (PDSS) and social functioning was assessed using the Global Assessment of Functioning (GAF) scale. Our results revealed that patients with PD had a significantly smaller volume of the right cornu ammonis (CA) 2/3 hippocampal subfield compared with HC. No significant associations were found between the volumes of the right CA 2/3 and the PDSS or GAF scores in correlation analyses. In conclusion, CA2/3 is thought to be related to contextual memory function, and our results suggest that this particular hippocampal subfield plays a role in the development of PD symptoms.

Abstract
Abstract. The brain and peripheral bodily organs continuously exchange information. Exemplary, interoception refers to the processing and perception of ascending information from the body to the brain. Stress responses involve a neurobehavioral cascade, which includes the activation of peripheral organs via neural and endocrine pathways and can thus be seen as an example for descending information on the brain-body axis. Hence, the interaction of interoception and stress represents bi-directional communication on the brain-body axis. The main hypothesis underlying this review is that the dysregulation of brain-body communication represents an important mechanism for the generation of physical symptoms in stress-related disorders. The aims of this review are, therefore, (1) to summarize current knowledge on acute stress effects on different stages of interoceptive signal processing, (2) to discuss possible patterns of abnormal brain-body communication (i.e., alterations in interoception and physiological stress axes activation) in mental disorders and chronic physical conditions, and (3) to consider possible approaches to modify interoception. Due to the regulatory feedback loops underlying brain-body communication, the modification of interoceptive processes (ascending signals) may, in turn, affect physiological stress axes activity (descending signals), and, ultimately, also physical symptoms.

Abstract
AbstractBackground– Earlier studies on the influence of pregnancy and postpartum period on the course of panic disorder have been inconsistent. The present study aims to quantify panic manifestations in these periods in large sample of women.Method– Panic manifestations, including exacerbations and new manifestations of panic disorder, were assessed retrospectively in a sample of 128 women with panic disorder with or without agoraphobia, 93 of whom had had 195 pregnancies.Results– Panic manifestations were fewer during pregnancy and more frequent in the postpartum period when compared with the control period. Women who had never been pregnant had significantly more panic manifestations than women with prior pregnancies. Breastfeeding and miscarriages did not have a significant effect. Women with postpartum panic reported more psychosocial stress events during this period.Conclusions– Possible reasons for postpartum panic and the protective effects of pregnancy are discussed, including psychosocial or hormonal factors and other neurobiological changes. Postpartum panic coincides with a sudden drop of hormones after delivery.

Abstract
Previous studies have reported dysfunction in the hypothalamic-pituitary-adrenal (HPA) axis in patients with major depressive disorder (MDD). Outpatients diagnosed with MDD (n = 199) underwent psychological evaluation, and were followed up with a phone interview after 6 months, using the Patient Health Questionnaire (PHQ-9). At 6-month follow-up, 59 out of 199 patients with MDD were still depressed (29.5%), as shown by scores ≥ 10 on the PHQ-9. The depressed group at follow-up showed significantly higher anxiety and suicidality levels at baseline than the non-depressed group at follow-up. Among the complete blood counts, lipid profiles, and hormone levels, adrenocorticotropic hormone (ACTH) was the only parameter that was significantly increased in the still depressed group. Levels higher than 40 pg/mL of ACTH at baseline were associated with higher depression scores at follow-up. Multiple linear regression analyses revealed that ACTH and cortisol predicted depression scores at follow-up, after controlling for baseline depression scores. Increased ACTH level at baseline may predict ongoing symptoms and severity of depression at follow-up, suggesting the role of dysfunctional HPA axis in MDD prognosis.

Abstract
Previous findings on the dysfunction of hypothalamic-pituitary-adrenal (HPA) axis in generalized anxiety disorder (GAD) are controversial, and the molecular mechanisms underlying such dysfunction remain unclear. We analyzed the methylation status of the NR3C1 1F promoter and the expression of glucocorticoid receptor-α isoform (GRα) in peripheral blood mononuclear cells (PMBCs), the basal cortisol level in serum, and a functional neuroendocrine marker for GR sensitivity in the PMBCs in 64 patients with current GAD and 85 healthy controls. We found that patients with GAD had significantly elevated levels of morning basal serum cortisol (P < 0.0001) and diminished GR sensitivity in the PBMCs (P < 0.0001) compared with healthy controls. The overall methylation levels across NR3C1 1F promoter (P < 0.0001) and percent methylation at each of the 5 CpG sites including CpG12, 21, 30, 31, and 32 (P < 0.001) significantly increased. Accordingly, the mRNA levels of GRα significantly decreased (P < 0.0001) in the PBMCs in patients with GAD compared with healthy controls, with the effects specific in patients without childhood traumatic experience. Moreover, both serum basal cortisol levels and GR sensitivity in the PBMCs were negatively correlated with the overall methylation levels of the NR3C1 1F promoter (P < 0.0001) and positively correlated with GRα mRNA levels (P = 0.007) in the PBMCs. In sum, our study revealed the increased activity of the HPA axis and diminished peripheral glucocorticoid responsiveness of GR underlying episodes of GAD. Furthermore, such dysfunction of the HPA axis is associated with both increased DNA methylation of NR3C1 1F promoter and decreased GRα expression.

Abstract
BACKGROUND It is unclear whether hypothalamic-pituitary-adrenal axis is involved in the pathophysiology of panic disorder (PD). The findings remain inconsistent. Cortisol awakening response (CAR) is a noninvasive biomarker of stress system activity. We designed the study to assess CAR in drug-naïve PD patients. MATERIALS AND METHODS We assessed CAR in 14 psychotropic drug-naïve outpatients with PD and 14 healthy controls. The severity of PD was assessed with Panic and Agoraphobia Scale. The severity of anxiety and depression was screened with Hospital Anxiety and Depression Scale. RESULTS No significant difference in CAR between PD patients and control group was found. No correlations were observed between CAR and anxiety severity measures in PD patients and controls. LIMITATIONS The number of participating subjects was relatively small, and the study results apply to nonsuicidal drug-naïve PD patients without agoraphobia and with short-illness duration. There was a lack of control on subjects' compliance with the sampling instructions. CONCLUSION The study provides no support for elevated CAR levels in drug-naïve PD patients without agoraphobia.

Abstract
As prevalence of anxiety, posttraumatic stress, and obsessive compulsive disorders continue to rise worldwide, increasing focus has been placed on immune mediated theories in understanding the underlying mechanisms of these disorders. Associations between the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and these disorders have been recognized in the scientific literature, specifically in regard to cortisol levels, as well as changes in pro- and anti-inflammatory cytokines. The present commentary will systematically assess the scientific literature within the past decade in regard to the psychoneuroimmunology of anxiety, posttraumatic stress, and obsessive compulsive disorders. Understanding the mechanisms of these disorders is essential in order to determine efficacious and targeted treatment strategies, which may lead to substantial improvements in overall functioning, as well as significant decreases in societal and economic burden.

Abstract
Evidence of aberrant hypothalamic-pituitary-adrenocortical (HPA) activity in many psychiatric disorders, although not universal, has sparked long-standing interest in HPA hormones as biomarkers of disease or treatment response. HPA activity may be chronically elevated in melancholic depression, panic disorder, obsessive-compulsive disorder, and schizophrenia. The HPA axis may be more reactive to stress in social anxiety disorder and autism spectrum disorders. In contrast, HPA activity is more likely to be low in PTSD and atypical depression. Antidepressants are widely considered to inhibit HPA activity, although inhibition is not unanimously reported in the literature. There is evidence, also uneven, that the mood stabilizers lithium and carbamazepine have the potential to augment HPA measures, while benzodiazepines, atypical antipsychotics, and to some extent, typical antipsychotics have the potential to inhibit HPA activity. Currently, the most reliable use of HPA measures in most disorders is to predict the likelihood of relapse, although changes in HPA activity have also been proposed to play a role in the clinical benefits of psychiatric treatments. Greater attention to patient heterogeneity and more consistent approaches to assessing treatment effects on HPA function may solidify the value of HPA measures in predicting treatment response or developing novel strategies to manage psychiatric disease.

Abstract
Functional hypercortisolism (FH) is caused by conditions able to chronically activate hypothalamic-pituitary-adrenal axis and usually occurs in cases of major depression, anorexia nervosa, bulimia nervosa, alcoholism, diabetes mellitus, simple obesity, polycystic ovary syndrome, obstructive sleep apnea syndrome, panic disorder, generalized anxiety disorder, shift work, and end-stage renal disease. Most of these states belong to pseudo-Cushing disease, a condition which is difficult to distinguish from Cushing's syndrome and characterized not only by biochemical findings but also by objective ones that can be attributed to hypercortisolism (e.g., striae rubrae, central obesity, skin atrophy, easy bruising, etc.). This hormonal imbalance, although reversible and generally mild, could mediate some systemic complications, mainly but not only of a metabolic/cardiovascular nature, which are present in these states and are largely the same as those present in Cushing's syndrome. In this review we aim to discuss the evidence suggesting the emerging negative role for FH.

Abstract
Anxiety disorders are common and distressing medical conditions, which typically arise in adolescence or early adult life. They can persist for many years, reducing quality of life, limiting academic and occupational achievement, and being responsible for considerable economic pressures. Although a range of psychological and pharmacological treatments are available, their success is often limited, and many patients remain troubled by significant symptom-related disability for long periods. The detailed pathophysiology of each anxiety disorder is not established, and novel treatments that are based solely on current understanding of conventional neurotransmitter function are unlikely to be substantially more effective or better tolerated than current treatments. Investigations of hypothalamo-pituitary axis function across panic disorder, generalized anxiety disorder, specific phobias and social anxiety disorder have produced intriguing findings but not revealed a consistent pattern of endocrine disturbance, perhaps reflecting differences in methodology and the nature and size of the clinical samples. There is a persistent need for large, prospective studies using standardized methods for investigation and data analysis (164 words).

Abstract
Current suicidal ideation and attempts are more commonly found in female patients with major depressive disorder (MDD) than in males. However, little is known about the relationship between activity of female reproductive hormones and suicide. The study population consisted of 490 female MDD patients of age ≥18. They were assessed by the Mini-International Neuropsychiatric Interview. At the same visit, we measured blood Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), estradiol, progesterone, Adrenocorticotropic Hormone (ACTH), cortisol, thyroid hormones, and prolactin. Blood FSH showed a significant difference among female MDD patients with suicide attempt, those with ideation, and those without within the previous month. Post-hoc analysis also showed that FSH was significantly lower in MDD patients with suicide attempt and ideation than those without, whereas other hormones showed no differences between those with and without attempt. FSH was negatively associated with current suicidality scores after adjustment for age and education years in all age groups. FSH was significantly lower in those with current suicide ideation or attempt than those without in age 45 years or under, but not in other age groups. In conclusion, blood FSH is significantly lower in female MDD patients with current suicide attempt or ideation than those without, especially in age 45 years or under.

Abstract
INTRODUCTION Alterations of the hypothalamic-pituitary-adrenal (HPA) axis and of its peripheral indices have been reported in both normal and pathological anxiety with controversial findings. The aim of the present study was to investigate the possible correlations between serum cortisol and dehydroepiandrosterone-sulfate (DHEA-S) levels and DHEA-S/cortisol ratio, and panic-agoraphobic spectrum dimensions in a sample of healthy subjects. METHODS Forty-two healthy subjects of both sexes, with no current or lifetime psychiatric disorders, were assessed by means of the Structured Clinical Interview for DSM-IV (SCID-I/P) and the so-called Panic Agoraphobic Spectrum-Self Report lifetime version (PAS-SR). RESULTS Significant, negative correlations were found between cortisol levels and the total score of the separation sensitivity, panic-like symptoms, and medication/substance sensitivity PAS-SR domains. The PAS-SR total and the panic-like symptoms domain scores were positively related to the DHEAS/cortisol ratio. When the sample was divided in women and men, these correlations were present in women only. DISCUSSION These findings, while indicating the presence of significant relationships between panic-agoraphobic traits and some indices of HPA axis functioning in healthy women, would suggest this as one of the factors explaining the greater vulnerability of women to cross the line between normal and pathological anxiety. CONCLUSIONS Further studies are needed to explore gender differences in the relationships between HPA axis alterations and the panic-agoraphobic spectrum dimensions.

Abstract
INTRODUCTION Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is hypothesized to play a role in the pathogenesis of bipolar disorder (BD). Conflicting results have been reported when saliva or serum was used to measure cortisol levels. A recently developed method is to measure cortisol in scalp hair, with 1cm of scalp hair representing 1 month. We studied whether there are differences in long-term hair cortisol levels between BD patients and healthy individuals and whether there are associations between hair cortisol and disease characteristics. METHODS Hair samples were collected in 100 BD patients and 195 healthy controls. Long-term cortisol levels were determined in 3 cm hair segments. Saliva samples were collected on two consecutive evenings. Documented disease characteristics were disease state, age of onset and psychiatric co-morbidity. RESULTS Hair cortisol levels were not statistically different in BD patients compared to healthy controls (p=0.233) and were not associated with the disease state at the moment of sample collection (p=0.978). In the subgroup of patients with age of onset ≥ 30 years, hair cortisol levels were significantly elevated compared to the subgroup with age of onset <30 years and to healthy controls (p=0.004). Psychiatric co-morbidity was associated with elevated cortisol levels (44.87 versus 31.41 pg/mg hair; p=0.021), with the exclusion of panic disorder, which was associated with decreased cortisol levels (22.13 versus 34.67 pg/mg hair; p=0.019). CONCLUSIONS Elevated long-term cortisol levels might play a role in a subgroup of patients with BD. There may be differences in pathogenesis of younger and older onset BD suggesting two different disease entities.

Abstract
Anxiety disorders are among the most common of all mental disorders and their pathogenesis is a major topic in psychiatry, both for prevention and treatment. Early stressful life events and alterations of hypothalamic pituitary adrenal (HPA) axis function seem to have a significant role in the onset of anxiety. Existing data appear to support the mediating effect of the HPA axis between childhood traumata and posttraumatic stress disorder. Findings on the HPA axis activity at baseline and after stimuli in panic disordered patients are inconclusive, even if stressful life events may have a triggering function in the development of this disorder. Data on the relationship between stress, HPA axis functioning and obsessive-compulsive disorder (OCD) are scarce and discordant, but an increased activity of the HPA axis is reported in OCD patients. Moreover, normal basal cortisol levels and hyper-responsiveness of the adrenal cortex during a psychosocial stressor are observed in social phobics. Finally, abnormal HPA axis activity has also been observed in generalized anxiety disordered patients. While several hypothesis have attempted to explain these findings over time, currently the most widely accepted theory is that early stressful life events may provoke alterations of the stress response and thus of the HPA axis, that can endure during adulthood, predisposing individuals to develop psychopathology. All theories are reviewed and the authors conclude that childhood life events and HPA abnormalities may be specifically and transnosographically related to all anxiety disorders, as well as, more broadly, to all psychiatric disorders.

Associations between DSM-IV diagnosis, psychiatric symptoms and morning cortisol levels in a community sample of adolescents. Soc Psychiatry Psychiatr Epidemiol 2012; 47:723-33. [PMID: 21476012 PMCID: PMC3328669 DOI: 10.1007/s00127-011-0374-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2010] [Accepted: 03/21/2011] [Indexed: 01/30/2023]
Abstract
PURPOSE Dysfunction of the hypothalamic-pituitary-adrenocortical axis (HPA-axis) is implicated in a variety of psychiatric and emotional disorders. In this study, we explore the association between HPA-axis functioning, as measured by morning cortisol, and common psychiatric disorders and symptoms among a community sample of adolescents. METHOD Data from a cross-sectional school-based survey of 501 school pupils, aged 15, were used to establish the strength of association between salivary morning cortisol and both diagnosis of psychiatric disorders and a number of psychiatric symptoms, as measured via a computerised psychiatric interview. Analysis, conducted separately by gender, used multiple regressions, adjusting for relevant confounders. RESULTS With one exception (a positive association between conduct disorder symptoms and cortisol among females) there was no association between morning cortisol and psychiatric diagnosis or symptoms. However, there was a significant two-way interaction between gender and conduct symptoms, with females showing a positive and males a negative association between cortisol and conduct symptoms. A further three-way interaction showed that while the association between cortisol and conduct symptoms was negative among males with a few mood disorder symptoms, among females with many mood symptoms it was positive. CONCLUSIONS Except in relation to conduct symptoms, dysregulation of morning cortisol levels seems unrelated to any psychiatric disorder or symptoms. However, the relationship between cortisol and conduct symptoms is moderated by both gender and mood symptoms. Findings are compatible with the recent work suggesting research should concentrate on the moderated associations between gender, internalising and externalising symptoms and cortisol, rather than any simple relationship.

Abstract
RESEARCH QUESTIONS Wearing a protective mask is compulsory for those in professions such as fire-fighters, rescue personnel and soldiers. The phobia to wear a protective mask is considered a specific claustrophobia and may become of major concern during military service. To date, no data are available with respect to the hypothalamus-pituitary-adrenocortical system activity (HPA SA) for both the so-called protective mask phobia (PMP) and its treatment. The aim of the present study was three-fold: 1) to assess HPA SA in soldiers suffering from PMP before and after intensive cognitive-behavioral treatment, 2) to compare these data with controls, and 3) to relate these data to subjective sleep. METHODS 46 Swiss Army recruits suffering from PMP were enrolled in a two-day intensive treatment course. During initial and final assessments, saliva was sampled to analyse HPA SA via salivary cortisol; saliva samples were also gathered in the morning. For comparison, saliva samples were gathered of 39 Emergency Rescue Service (ERS) recruits. All participants also completed a questionnaire related to sleep and to anxiety. RESULTS Compared to controls from the ERS, among army recruits suffering from PMP, cortisol secretion was significantly higher during initial and final assessments, and in the morning. Cortisol secretion decreased from initial and final assessment. Subjectively assessed sleep was more impaired in recruits suffering from PMP compared to controls. After cognitive-behavioral treatment, all recruits suffering from PMP were able to wear the protective mask. CONCLUSIONS Specific phobia about wearing a protective mask is treatable via a two-day intensive course. Treatment success is reflected in modified HPA SA. Methodology and results may be transferred to treat patients suffering from sleep apnea syndrome and presenting high anxiety about wearing continuous positive airway pressure devices.

Abstract
Previous research has demonstrated that individuals with panic disorder (PD) report significant sleep disturbances, although the mechanism of this disturbance is not clear. Patients with PD tend to report abnormally high levels of anxiety sensitivity (AS). Because higher AS involves increases in attention and fearfulness about anxiety and associated physical sensations, which in turn may cause excessive psychological and physiologic arousal, we hypothesized that amongst individuals with PD, higher AS would be associated with sleep disruption, particularly in the form of increased sleep latency. As expected, PD was associated with poorer sleep as measured by the Global Pittsburgh Sleep Quality Index (PSQI) compared to controls and AS was significantly associated with longer sleep latency. Our data suggest that sleep disturbance, and in particular sleep latency, in PD may be partly due to high levels of AS, which can be targeted with cognitive-behavioral therapeutic strategies.

Abstract
OBJECTIVE To examine the association between several subtypes of anxiety disorders and various cortisol indicators in a large cohort study. Anxiety disorders have been suggested to be linked to hypothalamic-pituitary-adrenal (HPA) axis activity, although results are scarce and inconsistent. No earlier studies have examined consistency of HPA axis findings across several anxiety subtypes and whether associations are state or trait dependent. METHODS Data are derived from 1427 participants of the Netherlands Study of Depression and Anxiety. Three groups were compared: 342 control participants without psychiatric disorders; 311 persons with a remitted (no current) anxiety disorder (social phobia, generalized anxiety disorder, panic disorder); and 774 persons with a current anxiety disorder, as diagnosed using the Composite International Diagnostic Interview psychiatric interview. Cortisol levels were measured in seven saliva samples, determining the 1-hour cortisol awakening response, evening cortisol, and cortisol response after 0.5 mg of dexamethasone ingestion. RESULTS Current anxiety disorder was associated with higher awakening cortisol levels (p = .002). These findings were mainly present for patients with panic disorder with agoraphobia and anxious patients with comorbid depressive disorder. Remitted anxiety only showed a trend toward higher morning cortisol (p = .08). No associations were observed for anxiety status and evening cortisol level or cortisol suppression after dexamethasone. CONCLUSIONS This study showed a modest but significantly higher 1-hour cortisol awakening response among anxiety patients, which was driven by those with panic disorder with agoraphobia and those with comorbid depression.

Abstract
Stressful life events increase the susceptibility for subsequent onset of psychiatric disorders in humans. Previous research has implicated neurotrophins in the onset of some stress-related diseases, such as major depression disorder, post-traumatic stress disorder or panic disorder. We have tested the hypothesis that the neurotrophin-3 (NT-3)/TrkC system is a genetic interface mediating the deleterious effects of stress on the initiation of panic disorder and other pathologies. To this aim, we have analyzed the functionality of HPA axis and the behavioral consequences of different types of stressful conditions in a mouse model of panic disorder, which overexpresses TrkC, the high affinity-receptor for NT-3 (TgNTRK3). Our results reveal that TgNTRK3 mice exhibit an altered circadian corticosterone rhythm that is reversed by clonidine treatment, but normal expression of genes involved in the control of the hypothalamus-pituitary-adrenal (HPA) axis (CRH, GR) and normal corticosterone response to acute and chronic stressors. In contrast, they exhibit an altered pattern of activation of stress-related brain areas and showed enhanced anxiety-related behavior and more passive strategies than wild types under some chronic stress conditions. We conclude that TgNTRK3 mice present differences in their response to stress characterized by subtle changes in the HPA axis, marked changes in acute stress-induced brain activation and altered coping strategies, suggesting a key role of TrkC receptor in the stress neural circuitry and in the behavioral consequences of chronic stress.

Abstract
Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis may play a role in panic disorder. HPA studies in patients with panic disorder, however, have produced inconsistent results. Seeking to understand the inconsistencies, we reexamined endocrine data from four studies of patients with panic disorder, in light of animal data highlighting the salience of novelty, control, and social support to HPA axis activity. Patients with panic disorder were studied (1) at rest over a full circadian cycle, (2) before and after activation by a panicogenic respiratory stimulant (doxapram) that does not directly stimulate the HPA axis, and (3) before and after a cholecystokinin B (CCK-B) agonist that is panicogenic and does directly stimulate the HPA axis. Patients with panic disorder had elevated overnight cortisol levels, which correlated with sleep disruption. ACTH and cortisol levels were higher in a challenge paradigm (doxapram) than in a resting state study, and paradigm-related ACTH secretion was exaggerated in patients with panic disorder. Panic itself could be elicited without HPA axis activation. Patients with panic disorder showed an exaggerated ACTH response to pentagastrin stimulation, but this response was normalized by prior exposure to the experimental context or psychological preparation to reduce novelty and enhance sense of control. Novelty is one of a number of contextual cues known from animal work to activate the HPA axis. The HPA axis abnormalities seen in patients with panic disorder in the four experiments reviewed here might all be due to exaggerated HPA axis reactivity to novelty cues. Most of the published panic/HPA literature is consistent with the hypothesis that HPA axis dysregulation in panic is due to hypersensitivity to contextual cues. This hypothesis requires experimental testing.

Abstract
Anxiety and depressive disorders are among the most common psychiatric disorders with a high number of hospital admissions and a lifetime prevalence of up to 25%. So far, the pathophysiological mechanisms for anxiety disorders remain to be found. Preclinical studies suggest that changes in hypothalamic-pituitary-adrenocortical (HPA) system function are causally related to the expression of anxiety-related behavior. The findings on HPA system function in patients with anxiety disorders are, however, heterogeneous. Both hypo- and hyperresponsiveness of HPA response in various anxiety disorders under different experimental conditions were found. In order to characterize putative case/control differences in HPA system function, we performed a Dex-CRH test, a widely used test to pick up changes in HPA system regulation with high sensitivity, in 30 patients with panic disorder, 35 patients with major depressive episode and in 30 controls individually matched for ethnicity, age and gender. The results indicate a similar dysregulation of the HPA system response in the Dex-CRH test in both patient groups. This finding further underlines the hypothesis that both, depression and panic disorder, share impaired HPA system regulation, supporting the notion that the impairment is involved in the pathophysiology of these clinical conditions. However, differences in the suppression effects and psychopathological correlation patterns between depressed and panic patients suggest different biological mechanisms of HPA system dysregulation in both disorders.

Abstract
Corticotropin-releasing factor (CRF) and the related urocortin peptides mediate behavioral, cognitive, autonomic, neuroendocrine and immunologic responses to aversive stimuli by activating CRF(1) or CRF(2) receptors in the central nervous system and anterior pituitary. Markers of hyperactive central CRF systems, including CRF hypersecretion and abnormal hypothalamic-pituitary-adrenal axis functioning, have been identified in subpopulations of patients with anxiety, stress and depressive disorders. Because CRF receptors are rapidly desensitized in the presence of high agonist concentrations, CRF hypersecretion alone may be insufficient to account for the enhanced CRF neurotransmission observed in these patients. Concomitant dysregulation of mechanisms stringently controlling magnitude and duration of CRF receptor signaling also may contribute to this phenomenon. While it is well established that the CRF(1) receptor mediates many anxiety- and depression-like behaviors as well as HPA axis stress responses, CRF(2) receptor functions are not well understood at present. One hypothesis holds that CRF(1) receptor activation initiates fear and anxiety-like responses, while CRF(2) receptor activation re-establishes homeostasis by counteracting the aversive effects of CRF(1) receptor signaling. An alternative hypothesis posits that CRF(1) and CRF(2) receptors contribute to opposite defensive modes, with CRF(1) receptors mediating active defensive responses triggered by escapable stressors, and CRF(2) receptors mediating anxiety- and depression-like responses induced by inescapable, uncontrollable stressors. CRF(1) receptor antagonists are being developed as novel treatments for affective and stress disorders. If it is confirmed that the CRF(2) receptor contributes importantly to anxiety and depression, the development of small molecule CRF(2) receptor antagonists would be therapeutically useful.

Abstract
Zusammenfassung. Ätiologie, Symptomatik und Verlauf von Angststörungen sind multikausal zu erklären. Ein Teilaspekt der psychobiologischen Erklärungsansätze von Angststörungen sind endokrine Auffälligkeiten, anhand derer bestimmte Unterformen pathologischer Angst charakterisiert werden können. Vor allem die Hypothalamus-Hypophysen-Nebennierenrinde-Achse und das sympathiko-adrenomedulläre System werden im Zusammenhang mit Emotionsregulation und pathologischer Angst untersucht. Beide Hormonsysteme spielen bei der Anpassung an individuelle Belastungssituationen eine bedeutende Rolle und beeinflussen die psychobiologische Anpassung an angstauslösende Situationen nachhaltig. In dieser Überblicksarbeit werden endokrine Dysregulationen der o.g. Hormonsysteme für verschiedene Unterformen von Angststörungen aufgezeigt und bzgl. ihrer ätiologischen Bedeutsamkeit, auch unter Berücksichtigung genetischer Befunde, diskutiert. Darüber hinaus werden erste therapeutische Ansätze, bei denen psychoendokrinologische Methoden genutzt werden, aufgezeigt.

Abstract
BACKGROUND Studies of hypothalamic secretion of corticotropin-releasing hormone (CRH) in patients with panic disorder in the nonpanic state (using CRH tests) are contradictory. No data about the hypothalamic-pituitary response to metyrapone are available. METHODS Study participants included 14 patients with panic disorder (DSM-IV criteria) and 14 healthy control subjects who underwent a standard overnight metyrapone test and a combined metyrapone/low-dose dexamethasone test. RESULTS Significant treatment effects of metyrapone and combined metyrapone/dexamethasone were found on plasma corticotropin, cortisol, and 11-deoxycortisol, but no differences between patients and control subjects emerged. Considering visual analogue scale ratings of anxiety, tension, restlessness, and Beck Depression Inventory scores as covariates, no group effects were detected. CONCLUSIONS Standard overnight metyrapone tests do not support a hypersecretion of hypothalamic CRH in panic disorder. Furthermore, no evidence for increased glucocorticoid negative feedback in panic was found. Hypothalamic CRH secretion in the nonpanic state needs further research.

Abstract
The latest studies on psychopathology and biology of nocturnal (or sleep) panic attacks and other findings related to sleep in panic disorder are reviewed. While some of the newer articles doubt that nocturnal panics present a more severe variation of panic disorder, older studies and some newer articles support this notion. Some studies suggest that nocturnal panic maybe also be associated with other, more severe pathology. This interesting syndrome, or variant of disorder, may have its own etiology, psychopathology, and underlying biology.

Abstract
The inhalation of carbon dioxide (CO2) is commonly used in patients and volunteers as a means of producing anxiety or panic. It is generally believed that patients with panic disorder are more vulnerable to the effects of CO2 than patients with other anxiety disorders or healthy volunteers and there is speculation and debate as to the mechanism for this apparent sensitivity. Recent work from our group has shown that a single inhalation of 35% CO2 activates the hypothalamic-pituitary-adrenocortical (HPA) axis, increases blood pressure (BP) and increases subjective fear responses in healthy volunteers. Correlation analyses reveal a relationship between the changes in BP and the cortisol increase. These findings led us to postulate that a common mechanism may mediate these and the subjective responses to inhalation of CO2. We propose that the noradrenergic system, particularly the locus coeruleus (LC), but including the A1 and A2 cell groups, may be a key mediator of these responses. This article examines the evidence and discusses the results of studies from our laboratory in relation to a neuroanatomical model centring on the LC.

Abstract
OBJECTIVE Extensive research on the hypothalamic-pituitary-adrenal (HPA) axis response to stress has not clarified whether that axis is activated by phobic anxiety. We addressed this issue by measuring cortisol in situational phobics during exposure treatment. METHODS Salivary cortisol was measured in 11 driving phobics before and during three exposure sessions involving driving on crowded limited-access highways and compared with levels measured in 13 healthy controls before and during two sessions of driving on the same highways. For each subject, data collected in the same time period on a comparison nondriving day served as an individual baseline from which cortisol response scores were calculated. RESULTS Cortisol levels of driving phobics and controls did not differ on the comparison day. Phobics also had normal cortisol response scores on awakening on the mornings of the exposures but these were already increased 1 hour before coming to the treatment sessions. Phobics had significantly greater cortisol response scores during driving exposure and during quiet sitting periods before and afterward. These greater responses generally paralleled increases in self-reported anxiety. At the first exposure session, effect sizes for differences in cortisol response scores between the two groups were large. Initial exposure to driving in the first session evoked the largest responses. CONCLUSION The data demonstrate that the HPA axis can be strongly activated by exposure to, and anticipation of, a phobic situation.

Abstract
BACKGROUND Considerable research implicates over-activity of the hypothalamic-pituitary adrenal axis in the pathophysiology of adult mood and anxiety disorders. The current study evaluates the association between salivary cortisol concentrations and response to carbon-dioxide inhalation in children and adolescents with anxiety disorders, mood disorders, or no psychiatric illness. The central question was whether response to carbon-dioxide inhalation is associated with levels of hypothalamic-pituitary adrenal axis activation. If confirmed, this would relate hypothalamic-pituitary adrenal axis activation in juveniles, as in adults, and response to a well-studied respiratory procedure. METHODS Serial salivary cortisol samples were examined in 98 subjects (ages 9-17 years), including 62 subjects with an anxiety and/or mood disorder and 36 nonpsychiatrically ill comparisons. Samples were obtained upon arrival at the laboratory, following a tilt test, then before and immediately after a standard 5% carbon dioxide inhalation procedure. RESULTS Salivary cortisol levels pre-carbon-dioxide inhalation were significantly higher in patients sensitive to the anxiogenic effects of carbon dioxide (n = 20) than in patients who did not respond to carbon dioxide (n = 42) and in healthy subjects, none of whom were sensitive to carbon dioxide (n = 36); cortisol concentrations in the latter two groups were indistinguishable. Salivary cortisol did not increase during carbon-dioxide inhalation, irrespective of diagnostic group or degree of reactivity to the procedure. CONCLUSIONS The current data resemble data from studies of laboratory-induced panic among adult patients. In both groups, activation of the hypothalamic-pituitary adrenal axis is associated with the response to a standardized stressor. Similarly, as in adults, carbon-dioxide inhalation in juveniles does not produce a significant change in hypothalamic-pituitary adrenal axis activation.

Abstract
In recent years, dysfunction of hypothalamic-pituitary-adrenal (HPA) axis function has been implicated in a wide variety of psychiatric conditions. The importance of this system in responding to and coping with stress is well documented, and the integrity of such systems is of obvious significance to good mental health. The prefrontal cortex (PFC) is also heavily implicated in numerous psychopathological conditions. There is thus a growing interest in the potential role the PFC might play in regulating HPA function, and whether abnormalities of these systems are linked. The present paper reviews a number of recent animal studies which have attempted to elucidate the role of the PFC in regulation of HPA axis function, and how these systems may interact. It is concluded that the PFC is involved both in activating HPA responses to stress and in the negative feedback regulation of this system. Cerebral laterality is an important feature of this regulation, with the right PFC being most directly linked to stress-regulatory systems. On this basis, a number of parallels are drawn to the human literature, where asymmetrical disturbances in PFC activity may help explain associated patterns of HPA dysfunction.
