Health-related quality of life of patients with hypothalamic-pituitary-adrenal axis dysregulations: a cohort study

Long-Term Consequences of Cushing Syndrome: A Systematic Literature Review

It is held that the condition of endogenous chronic hypersecretion of cortisol (Cushing syndrome, CS), causes several comorbidities, including cardiovascular and metabolic disorders, musculoskeletal alterations, as well as cognitive and mood impairment. Therefore, CS has an adverse impact on the quality of life and life expectancy of affected patients. What remains unclear is whether disease remission may induce a normalization of the associated comorbid conditions. In order to retrieve updated information on this issue, we conducted a systematic search using the Pubmed and Embase databases to identify scientific papers published from January 1, 2000, to December 31, 2022. The initial search identified 1907 potentially eligible records. Papers were screened for eligibility and a total of 79 were included and classified by the main topic (cardiometabolic risk, thromboembolic disease, bone impairment, muscle damage, mood disturbances and quality of life, cognitive impairment, and mortality). Although the limited patient numbers in many studies preclude definitive conclusions, most recent evidence supports the persistence of increased morbidity and mortality even after long-term remission. It is conceivable that the degree of normalization of the associated comorbid conditions depends on individual factors and characteristics of the conditions. These findings highlight the need for early recognition and effective management of patients with CS, which should include active treatment of the related comorbid conditions. In addition, it is important to maintain a surveillance strategy in all patients with CS, even many years after disease remission, and to actively pursue specific treatment of comorbid conditions beyond cortisol normalization.

Holistic burden of illness in patients with endogenous Cushing's syndrome: A systematic literature review

OBJECTIVE

The objective of this systematic literature review (SLR) was to summarize the latest studies evaluating the burden of illness in endogenous Cushing's syndrome (CS), including the impact of CS on overall and domain-specific health-related quality of life (HRQoL) and the economic burden of CS to provide a holistic understanding of disease and treatment burden.

METHODS

An SLR was conducted in PubMed, MEDLINE and Embase using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist to identify peer-reviewed manuscripts and conference abstracts published in English from 2015 to December 4, 2020.

RESULTS

Forty-five publications were eligible for inclusion; data were extracted from 37 primary studies while 8 SLRs were included for reference only. Thirty-one studies reported HRQoL using validated patient reported outcome (PRO) measures in pre- or post-surgery, radiotherapy and pharmacotherapy patients. Overall, this SLR found that patients with CS have worse outcomes relative to healthy populations across specific dimensions, such as depression, despite an improvement in HRQoL post-treatment. These findings reveal that CS symptoms are not fully resolved by the existing care paradigm. Few studies report on the economic burden of CS and currently available data indicate a high direct healthcare system cost burden.

CONCLUSIONS

Patients with CS experience a significant, complex and multifactorial HRQoL burden. Symptom-specific burden studies are sparse in the literature and the understanding of long-term CS symptomatic burden and economic burden is limited. This review intends to provide an updated reference for clinicians, payers and other stakeholders on the burden of CS as reported in published literature and to encourage further research in this area.

Safety of withholding perioperative steroids for patients with pituitary resection with an intact hypothalamus-pituitary-adrenal axis: A meta-analysis of randomized clinical trials

INTRODUCTION

Several observational studies have evaluated the effects of pre-operative steroids (STER) for transsphenoidal pituitary removal in patients with an intact hypothalamus-pituitary-adrenal axis. However, a consensus built upon randomized studies has not been previously performed.

PURPOSE

To comprehensively evaluate the clinical effects of patients receiving STER when compared to those not receiving steroids (NOSTER) in transsphenoidal pituitary resection, a meta-analysis of randomized clinical trials (RCT) was conducted.

METHODS

A systematic review of the literature of RCTs comparing STER and NOSTER was performed in accordance with the PRISMA guidelines. Databases, including PUBMED, Cochrane Library, Web of Science, and Embase were queried. The primary outcomes were adrenal insufficiency (AI) and diabetes insipidus (DI) post-operatively.

RESULTS

A total of 4 final studies were included, in which 530 total patients were analyzed. The meta-analysis suggested that there was no significant difference between STER and NOSTER groups post-operatively related to transient AI (RR= 0.83, 95% CI [0.51-1.35], p = 0.45; I² = 52%), permanent AI (RR= 0.97, 95% CI [0.41-2.31], p = 0.95; I² = 0%), and permanent DI (RR= 0.62, 95% CI [0.16-2.33], p = 0.48; I² = 0%). Nevertheless, STER group had significantly lower rates of transient DI (RR= 0.60, 95% CI [0.38-0.95], p = 0.03; I² = 5%), and post-op hyponatremia (RR = 0.49, 95% CI [0.28-0.87], p = 0.02; I² = 0%).

CONCLUSION

This study demonstrates evidence from RCTs that patients receiving pre-operative STER are both safe and effective pre-operatively for resection of pituitary adenomas with an intact hypothalamus-pituitary-adrenal axis.

Cortisol response to psychosocial stress, mental distress, fatigue and quality of life in coronary artery disease patients

We aimed to explore the relationship between cortisol response to psychosocial stress, mental distress, fatigue and health related quality of life (HRQoL) in individuals with coronary artery disease (CAD) after recent acute coronary syndrome (ACS). A cross-sectional study initially included 113 subjects (88% men, 53 ± 7 years) 1-3 weeks after ACS. Cortisol response was assessed by measuring salivary cortisol during Trier Social Stress Test. Mental distress was measured with Hospital Anxiety and Depression Scale, State-Trait Anxiety Inventory, and Type D Scale-14. Fatigue symptoms were evaluated using Multidimensional Fatigue Inventory 20-items, while HRQoL was assessed with 36-Item Short Form Medical Outcome Questionnaire. After conducting multivariable linear regression analyses, diminished cortisol response sampled after Public speech (T3-T1, + 15 min) was significantly associated with higher anxiety symptoms (β = -0.224; p = 0.035), while diminished cortisol response sampled after preparation time (T2-T1, + 10 min) was significantly linked with the presence of Type D personality (β = -0.290; p = 0.006; β = -0.282; p = 0.008 respectively), even after controlling for confounders (i.e., sex, age, education, New York Heart Association functional class, beta-blockers and baseline levels of cortisol measures). We found that mental distress, but not fatigue and HRQoL, was linked with blunted cortisol response during anticipation time of psychosocial stress, independently of potential covariates.

Quality of Life in Craniopharyngioma: A Systematic Review

BACKGROUND

Craniopharyngiomas are morbid tumors that significantly reduce patients' quality of life (QoL). The lifelong burden of endocrine, visual, hypothalamic, and limbic dysfunction can have disastrous consequences for the physical and psychosocial health of patients. Elucidating the factors that influence QoL could guide therapeutic interventions to improve patient well-being.

METHODS

A systematic review was performed in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement using the PubMed and Medline databases. Studies that had reported patient QoL using validated metrics in both adult and pediatric populations were included. Bias and methodological rigor were assessed using the MINORS (methodological index for nonrandomized studies) criteria.

RESULTS

A total of 25 studies, including 2025 patients, were available for review. Most studies were small, retrospective, cohort studies with a high risk of bias. The QoL of the patients with craniopharyngioma was lower than that of the general population. Hypothalamic involvement was consistently the strongest predictor of QoL. Endocrinopathy contributed to morbidity but could be ameliorated by hormone replacement therapy. Social and emotional dysregulation and a poor memory are common complaints after surgery, and iatrogenic damage to the infundibulum, hypothalamus, limbic system, and frontal lobes might underlie these concerns. Sleep-wake cycle dysfunction and hypothalamic obesity are serious consequences of hypothalamic damage.

CONCLUSIONS

An experienced multidisciplinary team is necessary to optimally manage the complex cases of these patients. The poor QoL of patients with craniopharyngioma is multifactorial. However, the contribution of iatrogenesis is not insubstantial. Improved surgical techniques, focusing on hypothalamic preservation, and adjuvant treatment options are required to improve the well-being of these patients.

Subjective well-being in non-obese individuals depends strongly on body composition

While obesity has been correlated with welfare in the general population, there is not much data on the influence of body composition on welfare among the non-obese adult individuals. In this study, a total of 726 non-obese individuals from the general population were analyzed. The mean age was 46.8 ± 15.4 years and 42.1% of participants were male. The anthropometric measurements and dual energy X-ray absorptiometry (DEXA) were done. The mean value for the Satisfaction with Life Scale (SWLS) was 23.09 ± 5.43, for Euro Quality of Life Visual Analogue Scale (EQ-VAS) was 78.0 ± 14.5, and for the Beck Depression Inventory (BDI) was 6.7 ± 6.6. On the SWLS, the higher waist-hip ratio had a negative impact even after adjusting for age, gender, and concomitant diseases. EQ-VAS was inversely associated with android fat distribution and directly associated with muscle mass. BDI value was inversely associated with lower muscle mass, especially in lower limbs. The well-being of women was mainly associated with the distribution of adipose tissue and less with the distribution of muscle tissue-abdominal fat distribution has a particularly negative impact on well-being among women. In contrast, men's well-being depends more on muscle mass and to a lesser extent on the distribution of fat tissue-a positive significant effect has lean mass and a circumference of thigh below gluteal fold.

Efficacy of Treatments Targeting Hypothalamic-Pituitary-Adrenal Systems for Major Depressive Disorder: A Meta-Analysis

Abnormal hypothalamic-pituitary-adrenal (HPA) axis has been implicated in major depressive disorder (MDD). A number of studies have attempted to use HPA-modulating medications to treat depression. However, their results are inconsistent. The efficacy of these drugs for MDD remains uncertain. The aims of this meta-analysis were to determine the effect and safety profile of HPA-targeting medications for MDD. World of Science and PubMed databases were comprehensively searched up to March 2021. All randomized controlled trials (RCTs) and open-label trials exploring antiglucocorticoid and related medications in patients with depression were included. Standardized mean differences (SMDs) and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated for continuous or dichotomous outcomes, respectively. In the meta-analysis, we identified 16 RCTs and seven open-label studies that included 2972 subjects. Pooling the change data that assessed the efficacy across all included HPA-targeting medications for depression showed a significant difference between interventions and controls with very small heterogeneity after influence analysis (SMD = 0.138, 95%CI = 0.052, 0.224, p = 0.002; I² = 20.7%, p = 0.212). No obvious publication bias was observed (p = 0.127). Effectiveness remained significant in patients with MDD (SMD = 0.136, 95%CI = 0.049, 0.223, p = 0.002). Subgroup analysis showed a significant difference favoring mifepristone and vasopressin 1B (V_1B) receptor antagonist treatment. Adverse events were reported by 14 studies and our analysis of high-quality studies showed a significant difference in favor of controls (RR = 1.283, 95%CI = 1.134, 1.452, p = 0). Our study suggested that patients with MDD may benefit from mifepristone and V_1B receptor antagonist treatments that have tolerable side effects. HPA-based medications are promising for depression treatment. However, additional high-quality RCTs, including head-to-head trials, are needed.

Cushing Syndrome Associated Myopathy: It Is Time for a Change

Cushing syndrome is the result of excessive levels of glucocorticoids. Endogenous Cushing syndrome is rare with an incidence of two to three cases per million per year. Clinically, the presentation consists of a characteristic phenotype including skin symptoms and metabolic manifestations. A frequent co-morbidity with high impact on quality of life is Cushing syndrome associated myopathy. It characteristically affects the proximal myopathy, impairing stair climbing and straightening up. The pathophysiology is complex and involves protein degradation via the forkhead box O3 (FOXO3) pathway, intramuscular fat accumulation, and inactivity-associated muscle atrophy. Surgical remission of Cushing syndrome is the most important step for recovery of muscle function. Restoration depends on age, co-morbidities and postoperative insulin-like growth factor concentrations. At average, functionality remains impaired during the long-term compared to age and sex matched control persons. Growth hormone therapy in individuals with impaired growth hormone secretion could be an option but has not been proved in a randomized trial.

Towards a greater understanding of the psychosocial impact of the symptoms of pituitary conditions

Management of pituitary conditions can be problematic with many patients experiencing long-term psychological and social difficulties that impact on their quality of life. This study aimed to identify psychosocial symptoms associated with pituitary conditions that lead to poor quality of life and identify differences in symptomatology between patient groups. A survey using measures of psychological and social symptoms was sent to 2000 members of the Pituitary Foundation in January 2016. The survey was completed by 1062 patients (683 female), aged under 18 to over 65 years, using categorical age ranges. Physical and psychosocial symptoms including appearance issues, fatigue, anxiety and depression were reported. Using correlational and regression analyses, significant variation in symptoms were identified across gender, age range and condition type that were impairing patients' long-term functioning and impacting quality of life. There is a need for greater patient information and advice surrounding psychosocial symptoms of pituitary conditions.

Quality of life in Cushing's syndrome

Measurement of Health-Related Quality of Life (HRQoL) is emerging as an important clinical endpoint which complements diagnostic workup and contributes to place patients at the centre of the decision-making process through the recognition of their needs, concerns, goals and expectations. Chronic excessive cortisol exposure in Cushing's syndrome (CS) causes severe physical and psychological morbidity which invariably affects HRQoL during the active phase of the disease and even after successful treatment. This sustained deterioration of patient's wellbeing is partly related to the persistence of several features associated with prior cortisol excess, including affective disorders, cognitive dysfunctions and negative illness perception. The aim of this review is to summarize the most recent evidence on HRQoL in CS, including the main determinants of its impairment and the results of some educational programs specifically addressed to improve patient's coping abilities. The preliminary results of an unpublished survey on patient's unmet needs will also be presented.

Impact of Adrenalectomy on Cortisol-Producing Adenoma: Longitudinal Evaluation of Health-Related Quality of Life following Laparoscopic Adrenalectomy

INTRODUCTION

There is increasing interest in evaluating the quality of life of patients with cortisol-producing adrenocortical adenoma (CPA). Our objective was to assess patient-reported health-related quality of life (HRQOL) in patients with CPA compared to non-CPA.

METHODS

Between January 2012 and September 2015, a total of 24 and 62 patients who had laparoscopic adrenalectomy with CPA and non-CPA, respectively, were included in the study. General HRQOL was evaluated on Short Form 8 (SF-8) questionnaire. The SF-8 questionnaire was administered at preoperative baseline and at 3, 6, 9, 12, 18, and 24 months after adrenalectomy. The impact of changing 2 measures of the summary score on the physical component summary (PCS) and mental component summary (MCS) score of SF-8 was evaluated in prospective and longitudinal studies.

RESULTS

The baseline PCS score was significantly lower in the CPA than in the non-CPA group (43.6 vs. 49.0; p = 0.0075). Thereafter, the PCS score was significantly lower in the CPA group at 3, 6, 9, and 12 months postoperatively. The PCS score increased in the CPA group with no significant difference between both groups at 18 months (48.1 vs. 50.2; p = 0.1202) and 24 months (48.0 vs. 50.8; p = 0.3625) postoperatively. However, the baseline MCS score was not significantly different between the CPA and non-CPA group. The MCS score in both groups gradually increased with no significant differences between the groups at any time points after surgery. The PCS score was not significantly improved at all postoperative points than the baseline score in the CPA and non-CPA group. The MCS score was significantly improved than the baseline score from 6 months postoperatively only in the CPA group.

CONCLUSION

Our research suggests that laparoscopic adrenalectomy may contribute to improving the physical and mental function in HRQOL.

Dynamics of ACTH and Cortisol Secretion and Implications for Disease

The past decade has seen several critical advances in our understanding of hypothalamic-pituitary-adrenal (HPA) axis regulation. Homeostatic physiological circuits need to integrate multiple internal and external stimuli and provide a dynamic output appropriate for the response parameters of their target tissues. The HPA axis is an example of such a homeostatic system. Recent studies have shown that circadian rhythmicity of the major output of this system-the adrenal glucocorticoid hormones corticosterone in rodent and predominately cortisol in man-comprises varying amplitude pulses that exist due to a subhypothalamic pulse generator. Oscillating endogenous glucocorticoid signals interact with regulatory systems within individual parts of the axis including the adrenal gland itself, where a regulatory network can further modify the pulsatile release of hormone. The HPA axis output is in the form of a dynamic oscillating glucocorticoid signal that needs to be decoded at the cellular level. If the pulsatile signal is abolished by the administration of a long-acting synthetic glucocorticoid, the resulting disruption in physiological regulation has the potential to negatively impact many glucocorticoid-dependent bodily systems. Even subtle alterations to the dynamics of the system, during chronic stress or certain disease states, can potentially result in changes in functional output of multiple cells and tissues throughout the body, altering metabolic processes, behavior, affective state, and cognitive function in susceptible individuals. The recent development of a novel chronotherapy, which can deliver both circadian and ultradian patterns, provides great promise for patients on glucocorticoid treatment.

Adrenal Hypercortisolism: A Closer Look at Screening, Diagnosis, and Important Considerations of Different Testing Modalities

Although prolonged hypercortisolism is associated with increased mortality and substantial morbidity, the clinical signs and symptoms are wide ranging and often nonspecific, contributing to challenges in diagnosis, as well as treatment delays. Greater awareness is needed among clinicians to help identify which patients should undergo biochemical screening for excess cortisol. Several biochemical tests are available, each with important caveats that should be considered in the context of the individual patient. Cortisol secretion varies widely, further complicating the biochemical diagnosis of hypercortisolism, which relies on the use of definitive cutoff values. Patients with hypercortisolism resulting from adrenal adenomas, including those discovered incidentally, often do not present with overt Cushingoid features (plethora, striae, muscle weakness, moon facies, etc.). However, the consequences of prolonged exposure to even slight elevations in cortisol levels are profound, including increased risk of diabetes, hypertension, fractures, cardiovascular events, and mortality. Because most cases of hypercortisolism resulting from an adrenal adenoma can be managed, it is imperative to identify patients at risk and initiate testing early for the best outcomes. The aim of this report is to increase awareness of the indications for screening for hypercortisolism and to review the biochemical screening tests and diagnosis for hypercortisolism associated with adrenal adenomas.

Lack of functional remission in Cushing's syndrome

INTRODUCTION

Hypercortisolism leads to severe clinical consequences persisting after the onset of remission. These physical sequelae of cortisol exposure are known to profoundly impact the patient's quality of life. As psychological factors may be correlated with this quality of life, our objective was to determine the specific weight of psychological determinants of quality of life in patients in remission from hypercortisolism.

PATIENTS AND METHODS

In an observational study, 63 patients with hypercortisolism in remission were asked to complete exhaustive self-administered questionnaires including quality of life (WHOQoL-BREF and Cushing QoL), depression, anxiety, self-esteem, body image, and coping scales. Multivariate analyses were performed. Psychological variables relevant to the model were: anxiety, depression, self-esteem, body image, and positive thinking dimension of the Brief-COPE. Cortisol deficiency was defined as a potential confounder.

RESULTS

The median time since remission was 3 years. Patients had significantly lower quality of life and body satisfaction score than the French population and patients with chronic diseases. Depression significantly impaired all WHOQoL and Cushing QoL domains. A low body satisfaction score significantly impaired social relationships quality of life score. In total, 42.9% of patients still needed working arrangements, 19% had disability or cessation of work.

CONCLUSION

Patients in biological remission of hypercortisolism can rarely be considered as functionally cured: this is evidenced by altered quality of life, working arrangements, and chronic depression. A multidisciplinary management of these patients is thus mandatory on a long-term basis.

Quality of life in patients with adrenal disease: A systematic review

BACKGROUND

Evaluating the patient with adrenal disease is challenging due to the lack of precise clinical and biochemical parameters for disease control. Quality of life (QOL) evaluation aims to measure the patient's subjective experience.

OBJECTIVE

To describe how QOL is defined and measured in adrenal disease, critically appraise the use of QOL tools in published literature, discuss the implications of these findings and provide direction for further research in this field.

MATERIALS AND METHODS

We searched the Cochrane library, EMBASE, Google Scholar, PsycINFO, PubMed, Web of Science databases to identify only primary studies where self-reported QOL was measured as a parameter in adults with confirmed adrenal disease, and results presented in English. Key data were independently extracted from each study and adherence to reporting guidelines evaluated.

RESULTS

A total of 117 studies involving 13 717 subjects were included. The vast majority of studies did not define QOL. The most common approach was to combine generic and domain-specific tools, although disease-specific tools are increasingly being used. Adherence to reporting guidelines was variable. A narrative synthesis of the findings was performed.

CONCLUSION

We present the first systematic review of QOL in adrenal disease. Quality of life is reduced in patients with adrenal disease, irrespective of adrenal hyperfunction or hypofunction. Quality of life improved with therapy but was not completely reversed despite biochemical remission. Authors should adhere to consistent reporting practices which are interpretable by clinicians. Further research is required to explain the mechanisms driving impaired QOL and value of QOL evaluations in the clinical context.

Surviving ectopic Cushing's syndrome: quality of life, cardiovascular and metabolic outcomes in comparison to Cushing's disease during long-term follow-up

OBJECTIVE

Aim of our study was to analyze long-term outcome of patients with the ectopic Cushing's syndrome (ECS) compared to patients with Cushing's disease (CD) regarding cardiovascular, metabolic, musculoskeletal and psychiatric comorbidities.

DESIGN

Cross-sectional study in patients with ECS and CD in two German academic tertiary care centers.

METHODS

Standardized clinical follow-up examination was performed including health-related quality of life (QoL) in 21 ECS patients in long-term remission (≥18 months since successful surgery). Fifty-nine patients with CD in remission served as controls.

RESULTS

Time from first symptoms to diagnosis of Cushing's syndrome (CS) was shorter in ECS than in CD (8.5 (IQR: 30.3) vs 25 (IQR: 39.0) months, P = 0.050). ECS patients had lower self-reported psychiatric morbidity compared to CD (19% vs 43%, P = 0.050) at follow-up. Moreover, female ECS patients reported favorable scores for QoL in the SF-36 questionnaire (mental health: 92 (IQR: 30) vs 64 (IQR: 32) in CD, P = 0.010) and a Cushing-specific QoL questionnaire (73 (IQR: 18) vs 59 (IQR: 36) in CD, P = 0.030). In a pooled analysis of ECS and CD patients, QoL correlated with time from first symptoms until diagnosis of CS, but not with urinary free cortisol levels or serum cortisol after dexamethasone at the time of diagnosis. Long-term outcomes regarding hypertension, metabolic parameters, bone mineral density and grip strength were comparable in ECS and CD.

CONCLUSIONS

Our data support the concept that time of exposure to glucocorticoid excess appears to be a better predictor than peak serum cortisol levels at the time of diagnosis regarding long-term psychiatric morbidity and QoL.

Worse Health-Related Quality of Life at long-term follow-up in patients with Cushing's disease than patients with cortisol producing adenoma. Data from the ERCUSYN

OBJECTIVE

Hypercortisolism in Cushing's syndrome (CS) is associated with impaired health-related quality of life (HRQoL), which may persist despite remission. We used the data entered into the European Registry on Cushing's syndrome (ERCUSYN) to evaluate if patients with CS of pituitary origin (PIT-CS) have worse HRQoL, both before and after treatment than patients with adrenal causes (ADR-CS).

METHODS

Data from 595 patients (492 women; 83%) who completed the CushingQoL and/or EQ-5D questionnaires at baseline and/or following treatment were analysed.

RESULTS

At baseline, HRQoL did not differ between PIT-CS (n = 293) and ADR-CS (n = 120) on both EuroQoL and CushingQoL. Total CushingQoL score in PIT-CS and ADR-CS was 41 ± 18 and 44 ± 20, respectively (P = .7). At long-time follow-up (>1 year after treatment) total CushingQoL score was however lower in PIT-CS than ADR-CS (56 ± 20 vs 62 ± 23; P = .045). In a regression analysis, after adjustment for baseline age, gender, remission status, duration of active CS, glucocorticoid dependency and follow-up time, no association was observed between aetiology and HRQoL. Remission was associated with better total CushingQoL score (P < .001), and older age at diagnosis with worse total score (P = .01). Depression at diagnosis was associated with worse total CushingQoL score at the last follow-up (P < .001).

CONCLUSION

PIT-CS patients had poorer HRQoL than ADR-CS at long-term follow-up, despite similar baseline scoring. After adjusting for remission status, no interaetiology differences in HRQoL scoring were found. Age and presence of depression at diagnosis of CS may be potential predictors of worse HRQoL regardless of CS aetiology.

Ultradian rhythmicity of plasma cortisol is necessary for normal emotional and cognitive responses in man

Glucocorticoids (GCs) are secreted in an ultradian, pulsatile pattern that emerges from delays in the feedforward-feedback interaction between the anterior pituitary and adrenal glands. Dynamic oscillations of GCs are critical for normal cognitive and metabolic function in the rat and have been shown to modulate the pattern of GC-sensitive gene expression, modify synaptic activity, and maintain stress responsiveness. In man, current cortisol replacement therapy does not reproduce physiological hormone pulses and is associated with psychopathological symptoms, especially apathy and attenuated motivation in engaging with daily activities. In this work, we tested the hypothesis that the pattern of GC dynamics in the brain is of crucial importance for regulating cognitive and behavioral processes. We provide evidence that exactly the same dose of cortisol administered in different patterns alters the neural processing underlying the response to emotional stimulation, the accuracy in recognition and attentional bias toward/away from emotional faces, the quality of sleep, and the working memory performance of healthy male volunteers. These data indicate that the pattern of the GC rhythm differentially impacts human cognition and behavior under physiological, nonstressful conditions and has major implications for the improvement of cortisol replacement therapy.
