Time Adjustment of Hydrocortisone Doses During Shift Work in Patients with Adrenal Insufficiency

Shift work causes a disruption between the circadian system and the external light-dark cycle, but also a misalignment between various levels of the circadian system. There is no information on patients with adrenal insufficiency (AI) who are working shifts. The objective of the study was to analyze the hormone replacement therapy with hydrocortisone (HC) and the adaptation scheme in patients with AI on shifts. Patients working on shifts (n=15) from two German endocrine centers received a questionnaire regarding their therapy scheme, dose adaptations, working shifts, dose adaptations during working shifts, and occurrence of adrenal crisis. We observed that 20% of patients stated that they experience difficulties taking glucocorticoid replacement on time, 40% of patients reported these difficulties to occur only occasionally. Consequently, nearly half of the patients had forgotten to take their replacement therapy at some point. More than 50% of patients reported an adrenal crisis during the last two years. The timely adaptation of HC or of modified-release HC during shifts was very inhomogeneous. In conclusion, the adaptation schemes for HC dosing during shift work are currently not evidence-based but opinion-driven. Our findings highlight the need for further investigations of shift workers with AI.

Adrenal crisis-induced cardiogenic shock (ACCS): a comprehensive review

Adrenal insufficiency (AI) is a disorder in which inadequate glucocorticoid and mineralocorticoid hormone production leads to a variety of symptoms, including fatigue, weight loss, and nausea. In some patients with unknown AI, adrenal crisis-induced cardiogenic shock (ACCS) can be the first presentation, resulting in a fatal situation. The ACCS may exhibit unresponsiveness to inotropes and fluid therapy; thus, glucocorticoid administration is the primary vital intervention, making early detection of AI essential. Hence, in this study, we review the case reports demonstrating acute cardiomyopathies in the context of AI. The review addresses the suggested underlying mechanisms, including the diminished protective effects of glucocorticoids against catecholamines in AI. We also highlighted some clues to aid physicians in considering AI as a differential diagnosis in critically ill patients presenting cardiogenic shock.

A review of the interplay between Takotsubo cardiomyopathy and adrenal insufficiency: Catecholamine surge and glucocorticoid deficiency

BACKGROUND

Takotsubo Cardiomyopathy (TCM) is a transient heart condition often precipitated by stress and characterized by atypical ventricular ballooning. The interplay between TCM and Adrenal Insufficiency (AI), particularly the influence of catecholamine excess and glucocorticoid deficiency on TCM's pathogenesis in individuals with AI, warrants comprehensive exploration for a better understanding of TCM pathophysiology and establishment of potential therapeutic strategies.

METHODS

We conducted an extensive literature search via PubMed and Google Scholar, targeting reports on AI, heart failure, and cardiomyopathy, supplemented by forward and backward citation tracing. We analyzed 46 cases from 45 reports, assessing the clinical presentation and outcomes in the context of AI categorization.

RESULTS

In patients with AI, a glucocorticoid deficit appears to exacerbate the myocardial vulnerability to catecholamine toxicity, precipitating TCM. Most conditions were reversible; however, three pre-1990 cases resulted in irreversible outcomes.

CONCLUSIONS

The investigation into the AI and TCM intersection highlights the pathogenic significance of catecholamines in the absence of glucocorticoids. The data consolidates the hypothesis that glucocorticoid scarcity exacerbates the cardiac susceptibility to catecholaminergic toxicity, potentially triggering TCM. The study affirms glucocorticoids' cardioprotective roles and elucidates how catecholamine surges contribute to TCM pathogenesis, suggesting strategic clinical management adjustments for AI patients to reduce TCM incidence.

Long-term health consequences of congenital adrenal hyperplasia

Congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency accounts for 95% of all CAH cases and is one of the most common inborn metabolic conditions. The introduction of life-saving glucocorticoid replacement therapy 70 years ago has changed the perception of CAH from a paediatric disorder into a lifelong, chronic condition affecting patients of all age groups. Alongside health problems that can develop during the time of paediatric care, there is an emerging body of evidence suggesting an increased risk of developing co-morbidities during adult life in patients with CAH. The mechanisms that drive the negative long-term outcomes associated with CAH are complex and involve supraphysiological replacement therapies (glucocorticoids and mineralocorticoids), excess adrenal androgens both in the intrauterine and postnatal life, elevated steroid precursors and adrenocorticotropic hormone levels. Alongside a review of mortality outcome, we discuss issues that need to be addressed when caring for the CAH patient including female and male fertility, cardio-metabolic morbidity, bone health and other important long-term outcomes of CAH.

Incidence and Risk Factors for Adrenal Crisis in Pediatric-onset Adrenal Insufficiency: A Prospective Study

CONTEXT

Adrenal crisis (AC) is a life-threatening complication that occurs during follow-up of patients with adrenal insufficiency (AI). No prospective study has thoroughly investigated AC in children with primary and secondary AI.

OBJECTIVE

This work aimed to determine the incidence and risk factors for AC in patients with pediatric-onset AI.

METHODS

This multicenter, prospective cohort study conducted in Japan enrolled patients diagnosed with AI at age ≤15 years. The incidence of AC was calculated as events per person-year (PY), and risk factors for AC were assessed using Poisson regression multivariable analysis.

RESULTS

The study population comprised 349 patients (164 male, 185 female) with a total follow-up of 961 PY. The median age at enrollment was 14.3 years (interquartile range [IQR] 8.5-21.2 years), and the median follow-up was 2.8 years (IQR 2.2-3.3 years). Of these patients, 213 (61%) had primary AI and 136 (39%) had secondary AI. Forty-one AC events occurred in 31 patients during the study period. The calculated incidence of AC was 4.27 per 100 PY (95% CI, 3.15-5.75). Poisson regression analysis identified younger age at enrollment (relative risk [RR] 0.93; 95% CI, 0.89-0.97) and increased number of infections (RR 1.17; 95% CI, 1.07-1.27) as significant risk factors. Female sex (RR 0.99; 95% CI, 0.53-1.86), primary AI (RR 0.65; 95% CI, 0.30-1.41), or equivalent dosage of hydrocortisone per square meter of body area (RR 1.02; 95% CI, 0.96-1.08) was not a significant risk factor.

CONCLUSION

A substantial proportion of patients with pediatric-onset AI experience AC. Younger age and an increased number of infections are independent risk factors for developing AC in these patients.

Diagnosis and management of secondary adrenal crisis

Adrenal crisis (AC) is a life threatening acute adrenal insufficiency (AI) episode which can occur in patients with primary AI but also secondary AI (SAI), tertiary AI (TAI) and iatrogenic AI (IAI). In SAI, TAI and IAI, AC may develop when the HPA axis is unable to mount an adequate glucocorticoid response to severe stress due to pituitary or hypothalamic disruption. It manifests as an acute deterioration in multi-organ homeostasis that, if untreated, leads to shock and death. Despite the availability of effective preventive strategies, its prevalence is increasing in patients with SAI, TAI and IAI due to more frequent exogenous steroid administration, pituitary immune-related effects of immune checkpoint inhibitors and opioid use in pain management. The delayed diagnosis of acute AI which remains infrequently suspected increases the risk of AC. Its main precipitating factors are infections, emotional distress, surgery, cessation or reduction in GC doses, pituitary infarction or surgical cure of endogenous Cushing's syndrome. In patients not known previously to have SAI/TAI/IAI, recognition of its symptoms, signs, and biochemical abnormalities can be challenging and cause delay in proper diagnosis and therapy. Effective therapy of AC is rapid intravenous administration of hydrocortisone (initial bolus of 100 mg followed by 200 mg/24 h as continuous infusion or bolus of 50 mg every 6 h) and 0.9% saline. In diagnosed patients, preventive education in sick-day rules adjustment of glucocorticoid replacement and hydrocortisone parenteral self-administration must be performed repeatedly by trained health care providers. Strategies to improve the adequate preventive education in patients at risk for secondary AI should be promoted in collaboration with various medical specialist societies and patients support associations.

Iatrogenic adrenal insufficiency in adults

Iatrogenic adrenal insufficiency (IAI) is the most common form of adrenal insufficiency in adult patients, although its overall exact prevalence remains unclear. IAI is associated with adverse clinical outcomes, including adrenal crisis, impaired quality of life and increased mortality; therefore, it is imperative that clinicians maintain a high index of suspicion in patients at risk of IAI to facilitate timely diagnosis and appropriate management. Herein, we review the major causes, clinical consequences, diagnosis and care of patients with IAI. The management of IAI, particularly glucocorticoid-induced (or tertiary) adrenal insufficiency, can be particularly challenging, and the provision of adequate glucocorticoid replacement must be balanced against minimizing the cardiometabolic effects of excess glucocorticoid exposure and optimizing recovery of the hypothalamic-pituitary-adrenal axis. We review current treatment strategies and their limitations and discuss developments in optimizing treatment of IAI. This comprehensive Review aims to aid clinicians in identifying who is at risk of IAI, how to approach screening of at-risk populations and how to treat patients with IAI, with a focus on emergency management and prevention of an adrenal crisis.

Frequency of stress dosing and adrenal crisis in paediatric and adult patients with congenital adrenal hyperplasia: a prospective study

OBJECTIVE

Patients with congenital adrenal hyperplasia (CAH) require life-long glucocorticoid replacement, including stress dosing (SD). This study prospectively assessed adrenal crisis (AC) incidence, frequency, and details of SD and disease knowledge in adult and paediatric patients and their parents.

DESIGN

Prospective, observational study.

METHODS

Data on AC and SD were collected via a patient diary. In case of AC, medical records were reviewed and patient interviews conducted. Adherence to sick day rules of the German Society of Endocrinology (DGE) and disease knowledge using the German version of the CAH knowledge assessment questionnaire (CAHKAQ) were assessed.

RESULTS

In 187 adult patients, the AC incidence was 8.4 per 100 patient years (py) and 5.1 in 100 py in 38 children. In adults, 195.4 SD episodes per 100 py were recorded, in children 169.7 per 100 py. In children 72.3% and in adults 34.8%, SD was performed according to the recommendations. Children scored higher on the CAHKAQ than adults (18.0 [1.0] vs 16.0 [4.0]; P = .001). In adults, there was a positive correlation of the frequency of SD and the incidence of AC (r = .235, P = .011) and CAHKAQ score (r = .233, P = .014), and between the incidence of AC and CAHKAQ (r = .193, P = .026).

CONCLUSION

The AC incidence and frequency of SD in children and adults with CAH are high. In contrast to the paediatric cohort, the majority of SD in adults was not in accordance with the DGE recommendations, underlining the need for structured and repeated education of patients with particular focus on transition.

A Case of Type 2 Diabetes Mellitus with Lung Cancer Suffered from Euglycemic Diabetic Ketosis Accompanied by Adrenal Insufficiency after Immune Checkpoint Inhibitors

A 74-year-old patient with type 2 diabetes mellitus received basal-bolus insulin, insulin secretagogues, and sodium glucose transporter 2 (SGLT2) inhibitors. After immune checkpoint inhibitor treatment for lung cancer, he suffered from depressed consciousness with a urinary ketone body (3+). When all hypoglycemic treatments were discontinued, his serum blood glucose remained at 121 mg/dL. He was diagnosed with euglycemic diabetic ketosis. Endocrine loading tests revealed isolated adrenocorticotropic hormone (ACTH) deficiency as an immune-related adverse event. It was suggested that euglycemic diabetic ketosis was induced by the self-suspension of insulin and insulin secretagogues, adrenal insufficiency, SGLT2 inhibitors, and carbohydrate intake shortage.

Extensive Expertise in Endocrinology: Adrenal crisis in assisted reproduction and pregnancy

Appropriate management of adrenal insufficiency in pregnancy is challenging due to the rarity of both primary, secondary and tertiary forms of the disease as well as the lack of evidence-based recommendations to guide clinicians to glucocorticoid and sometimes also mineralocorticoid dosage adjustments. Debut of adrenal insufficiency during pregnancy requires immediate diagnosis as it can lead to adrenal crisis, intrauterine growth restriction and foetal demise. Diagnosis is difficult due to overlap of symptoms of adrenal insufficiency and its crisis with those of pregnancy. Adrenal insufficiency in stable replacement treatment needs careful monitoring during pregnancy to adapt to the physiological changes in the requirement of the adrenal hormones. This is hampered because the diagnostic threshold of most adrenocortical hormones is not applicable during pregnancy. The frequent use of assisted reproduction technology with controlled ovarian hyperstimulation in these patient groups with disease induced low fertility has created an unrecognised risk of adrenal crises due to accelerated oestrogen stimulation with increased risk of even be life-threatening complications for both the woman and foetus. The area needs consensus recommendations between gynaecologists and endocrinologists in tertiary referral centres to alleviate such increased gestational risk. Patient and partner education, use of the EU emergency card for management of adrenal crises can also contribute to better pregnancy outcomes. There is a strong need of more research on e.g. improvement of glucocorticoid replacement as well as crisis management treatment, and biomarkers for treatment optimisation in this field, which suffers from the rare nature of the diseases and poor funding.

Adrenal Crisis - Definition, Prevention and Treatment: Results from a Delphi Survey

Based on recent data, a total number of about 29 000 patients with adrenal insufficiency can be calculated for Germany, and about 1500 fatalities due to adrenal crises have to be expected within the next decade. Management of adrenal crises is still unsatisfactory. The objectives of this study were to establish consensus for diagnostic criteria, prevention strategies, and treatment recommendations for adrenal crises. The study was conducted from January 2022 to April 2023, using Delphi technique. Four rounds of questionnaires were sent to 45 experts, selected by a coordinating group on behalf of the adrenal section of the German Society of Endocrinology. The survey was implemented online using the REDCap web application. Responses were captured anonymously. During the Delphi process the expert panel developed diagnostic criteria to identify patients likely to have an adrenal crisis. Education about adrenal insufficiency among patients as well as non-endocrine medical personnel were regarded as highly important. It was suggested that recommendations for the management of adrenal insufficiency have to be simplified and made widely available. This study provides pragmatic strategies to identify and treat patients prone to adrenal crisis, thereby highlighting the need for an improved management of patients with adrenal insufficiency.

Serological Evidence and Self-reported Outcomes in Patients with Adrenal Insufficiency during the First Waves of COVID-19 in North-East Italy

OBJECTIVE

COVID-19 is a potentially serious new infection first reported in North East Italy in Spring, 2020. Patients with adrenal insufficiency (AI) have a known increased risk of infections that could precipitate to adrenal crisis. Even COVID-19-related psycho-social impact could affect their health, requiring a dynamic adaptation of daily glucocorticoid (GC) therapy. The aim of this study was to evaluate the incidence of COVID-19 infection and self-reported outcomes in AI patients after the first pandemic waves.

METHODS

It was an open-label, cross-sectional monocentric study on 84 (65 primary, 19 secondary) AI patients resident in Veneto and followed-up in our clinical Endocrine Unit. All patients underwent serological investigation of anti-SARS-CoV2 IgG, answered the purpose-built "ADDICOVID" questionnaire in August, 2020, and were re-contacted to reevaluate COVID-19 infection occurrence in March-April, 2021.

RESULTS

All patients resulted negative to the serological test for anti-SARS-CoV2 IgG at the end of the first pandemic wave. After the third wave, COVID-19 infection occurred in 8 patients without the need for hospitalization. Half patients felt an increased risk of COVID-19 infection, significantly associated with increased stress and GC stress dose. Only one patient reported stress-correlated adrenal crisis. The majority of AI workers changed working habits, significantly reducing COVID- 19-related stress.

CONCLUSION

AI patients did not show an increased incidence of COVID-19, but the perception of increased COVID-19 infection risk significantly impacted their psychological well-being, working habits, and GC daily doses. Therapeutic patient education is crucial, especially for AI workers, to prevent and treat situations that could lead to an adrenal crisis.

On Primary Adrenal Insufficiency with Normal Concentrations of Cortisol - Early Manifestation of Addison's Disease

Primary adrenal insufficiency (AI) is an endocrine disorder in which hormones of the adrenal cortex are produced to an insufficient extent. Since receptors for adrenal steroids have a wide distribution, initial symptoms may be nonspecific. In particular, the lack of glucocorticoids can quickly lead to a life-threatening adrenal crisis. Therefore, current guidelines suggest applying a low threshold for testing and to rule out AI not before serum cortisol concentrations are higher than 500 nmol/l (18 μg/dl). To ease the diagnostic, determination of morning cortisol concentrations is increasingly used for making a diagnosis whereby values of>350 nmol/l are considered to safely rule out Addison's disease. Also, elevated corticotropin concentrations (>300 pg/ml) are indicative of primary AI when cortisol levels are below 140 nmol/l (5 μg/dl). However, approximately 10 percent of our patients with the final diagnosis of primary adrenal insufficiency would clearly have been missed for they presented with normal cortisol concentrations. Here, we present five such cases to support the view that normal to high basal concentrations of cortisol in the presence of clearly elevated corticotropin are indicative of primary adrenal insufficiency when the case history is suggestive of Addison's disease. In all cases, treatment with hydrocortisone had been started, after which the symptoms improved. Moreover, autoantibodies to the adrenal cortex had been present and all patients underwent a structured national education program to ensure that self-monitored dose adjustments could be made as needed.

Major immunophenotypic abnormalities in patients with primary adrenal insufficiency of different etiology

Introduction

Patients with primary adrenal insufficiency (PAI) suffer from increased risk of infection, adrenal crises and have a higher mortality rate. Such dismal outcomes have been inferred to immune cell dysregulation because of unphysiological cortisol replacement. As the immune landscape of patients with different types of PAI has not been systematically explored, we set out to immunophenotype PAI patients with different causes of glucocorticoid (GC) deficiency.

Methods

This cross-sectional single center study includes 28 patients with congenital adrenal hyperplasia (CAH), 27 after bilateral adrenalectomy due to Cushing's syndrome (BADx), 21 with Addison's disease (AD) and 52 healthy controls. All patients with PAI were on a stable GC replacement regimen with a median dose of 25 mg hydrocortisone per day. Peripheral blood mononuclear cells were isolated from heparinized blood samples. Immune cell subsets were analyzed using multicolor flow cytometry after four-hour stimulation with phorbol myristate acetate and ionomycin. Natural killer (NK-) cell cytotoxicity and clock gene expression were investigated.

Results

The percentage of T helper cell subsets was downregulated in AD patients (Th1 p = 0.0024, Th2 p = 0.0157, Th17 p < 0.0001) compared to controls. Cytotoxic T cell subsets were reduced in AD (Tc1 p = 0.0075, Tc2 p = 0.0154) and CAH patients (Tc1 p = 0.0055, Tc2 p = 0.0012) compared to controls. NKCC was reduced in all subsets of PAI patients, with smallest changes in CAH. Degranulation marker CD107a expression was upregulated in BADx and AD, not in CAH patients compared to controls (BADx p < 0.0001; AD p = 0.0002). In contrast to NK cell activating receptors, NK cell inhibiting receptor CD94 was upregulated in BADx and AD, but not in CAH patients (p < 0.0001). Although modulation in clock gene expression could be confirmed in our patient subgroups, major interindividual-intergroup dissimilarities were not detected.

Discussion

In patients with different etiologies of PAI, distinct differences in T and NK cell-phenotypes became apparent despite the use of same GC preparation and dose. Our results highlight unsuspected differences in immune cell composition and function in PAI patients of different causes and suggest disease-specific alterations that might necessitate disease-specific treatment.

Predisposing factors for adrenal crisis in chronic adrenal insufficiency: a case-control study

OBJECTIVE

This study aims to identify susceptibility markers for adrenal crises (AC) in educated patients with chronic adrenal insufficiency (AI).

DESIGN

A case-control study involving 66 patients with AI analyzing the impact of glucocorticoid and mineralocorticoid exposure, adrenomedullary function, inflammatory parameters, and educational status on AC frequency. Patients were categorized into low (n = 32) and high (n = 34) AC frequency groups based on AC occurrence (below or 2 times above the average of the reported AC frequency of 8.3 AC/100 patient-years in a previous prospective study).

METHODS

Parameters, including cortisol plasma profile and urinary steroid excretion after administration of the morning glucocorticoid dose, 24-h urinary steroid profiling, salivary cortisol profiling, and hair cortisol, estimated cortisol exposure. Polymorphisms (single nucleotide polymorphism [SNP]) of the glucocorticoid receptor (NR3C1) and mineralocorticoid receptor (NR3C2) associated with individual steroid sensitivity were assessed together with SNPs for 11β-hydroxysteroid dehydrogenase 1 (HSD11B1) and 11β-hydroxysteroid dehydrogenase 2 (HSD11B2). Mineralocorticoid replacement was evaluated by serum and urinary electrolytes and osmolality, plasma-renin concentration, and ambulatory blood pressure levels. We additionally measured plasma and urinary catecholamines, serum levels of IL6 and hsCRP, and SNPs of IL6 and TNF-alpha. Patient knowledge of AC prevention was assessed by questionnaires.

RESULTS

Frequent AC patients had higher daily glucocorticoid doses and hair cortisol levels, with no significant differences in other parameters investigated. AC frequency is inversely correlated with the frequency of self-reported adjustments of the glucocorticoid replacement.

CONCLUSION

Higher glucocorticoid dosages in high-risk patients, despite unaffected cortisol metabolism, may be linked to decreased cortisol sensitivity or impaired glucocorticoid absorption. Proactive dose adjustments show a protective effect against AC, regardless of biological vulnerability.

Adrenal Emergencies

The adrenal glands drive physiologic homeostasis, with dysregulation in any direction causing multisystem dysfunction. Adrenal excess states include hyperaldosteronism which manifests with refractory hypertension and electrolyte abnormalities including hypernatremia and hypokalemia. Paragangliomas including pheochromocytoma can cause multisystem end-organ dysfunction due to catecholaminergic storm, which require rapid blood pressure control with phentolamine and identification of lesions amenable to surgical resection. Adrenal insufficiency states in contrast can result in hypotension and decompensation refractory to vasopressor administration, requiring adrenal supplementation via hydrocortisone.

Emergency and perioperative management of adrenal insufficiency in children and young people: British Society for Paediatric Endocrinology and Diabetes consensus guidance

Adrenal insufficiency (AI) is characterised by lack of cortisol production from the adrenal glands. This can be a primary adrenal disorder or secondary to adrenocorticotropic hormone deficiency or suppression from exogenous glucocorticoids. Symptoms of AI in children may initially be non-specific and include growth faltering, lethargy, poor feeding, weight loss, abdominal pain, vomiting and lingering illnesses. AI is treated with replacement doses of hydrocortisone. At times of physiological stress such as illness, trauma or surgery, there is an increased requirement for exogenous glucocorticoids, which if untreated can lead to an adrenal crisis and death. There are no unified guidelines for those <18 years old in the UK, leading to substantial variation in the management of AI. This paper sets out guidance for intercurrent illness, medical, dental and surgical procedures to allow timely and appropriate recognition and treatment of AI and adrenal crisis for children and young people.

Challenges in managing disorders of sex development associated with adrenal dysfunction

INTRODUCTION

Disorders of Sex Development (DSD) associated with adrenal dysfunction occur due to different defects in the proteins involved in gonadal and adrenal steroidogenesis.

AREAS COVERED

The deficiencies in 21-hydroxylase and 11β-hydroxylase lead to DSD in 46,XX patients, defects in StAR, P450scc, 17α-hydroxylase and 17,20-lyase lead to 46,XY DSD, and 3β-HSD2 and POR deficiencies cause both 46,XX and 46,XY DSD. Challenges in diagnosis arise from the low prevalence and the variability in serum steroid profiles. Replacement therapy with hydrocortisone and fludrocortisone helps to minimize life-threatening adrenal crises; however, availability is still an unresolved problem in many countries. Adverse health outcomes, due to the disease or its treatment, are common and include adult short stature, hypertension, osteoporosis, obesity, cardiometabolic risk, and reproductive health issues. Potential biomarkers to improve monitoring and novel treatment options that have been developed with the primary aim to decrease adrenal androgen production are promising tools to help improve the health and quality of life of these patients.

EXPERT OPINION

Steroid profiling by mass spectrometry and next-generation sequencing technologies represent useful tools for establishing an etiologic diagnosis and drive personalized management. Nonetheless, access to health care still remains an issue requiring urgent solutions in many resource-limited settings.

Primary adrenal insufficiency due to bilateral adrenal hemorrhage-adrenal infarction in a patient with systemic lupus erythematosus and antiphospholipid syndrome: case presentation and review of the literature

Primary adrenal insufficiency (PAI) is a rare disease which represents the end stage of a destructive process involving the adrenal cortex. Occasionally it may be caused by bilateral adrenal hemorrhagic infarction in patients with antiphospholipid syndrome (APS). We herein report the challenging case of a 30-year-old female patient with systemic lupus erythematosus (SLE) and secondary APS who was admitted to the emergency department (ED) due to fever, lethargy, and syncopal episodes. Hyponatremia, hyperkalemia, hyperpigmentation, shock, altered mental status, and clinical response to glucocorticoid administration were features highly suggestive of an acute adrenal crisis. The patient's clinical status required admission to the intensive care unit (ICU), where steroid replacement, anticoagulation, and supportive therapy were provided, with a good outcome. Imaging demonstrated bilateral adrenal enlargement attributed to recent adrenal hemorrhage. This case highlights the fact that bilateral adrenal vein thrombosis and subsequent hemorrhage can be part of the thromboembolic complications seen in both primary and secondary APS and which, if misdiagnosed, may lead to a life-threatening adrenal crisis. High clinical suspicion is required for its prompt diagnosis and management. A literature search of past clinical cases with adrenal insufficiency (AI) in the setting of APS and SLE was conducted using major electronic databases. Our aim was to retrieve information about the pathophysiology, diagnosis, and management of similar conditions.

Adrenal Crisis Associated With COVID-19 Vaccination in Patients With Adrenal Insufficiency

Vaccination is generally recommended for patients with adrenal insufficiency receiving glucocorticoid replacement therapy because they are at risk of experiencing adrenal crisis during infections. Conventional vaccinations, such as those for influenza virus, have rarely been associated with adrenal crisis in patients with adrenal insufficiency; therefore, increasing the glucocorticoid dose during vaccination is not necessarily recommended. The COVID-19 mRNA vaccines exhibit a higher degree of adverse reactions, including fever and general fatigue, than those of conventional vaccines. Here, we present 3 cases of adrenal crisis associated with mRNA COVID-19 (BNT162b2) vaccination in patients with secondary adrenal insufficiency. Two patients presented with adrenal crisis after the second dose, whereas 1 presented with adrenal crisis after the first dose. Within 24 hours of vaccination, all patients presented with fatigue and appetite loss, and 2 patients were febrile. None of them increased their glucocorticoid dosage at the time of vaccination, leading to an adrenal crisis. To date, 9 cases of adrenal crisis, including ours, associated with COVID-19 vaccination have been reported. Considering the high degree of adverse reactions to COVID-19 vaccination, administration of prophylactic stress dose of glucocorticoids is strongly recommended, particularly in patients with symptomatic adverse reactions, to protect them from adrenal crisis.

Using the behaviour change wheel and person-based approach to develop a digital self-management intervention for patients with adrenal insufficiency: the Support AI study protocol

Introduction

Most patients with Adrenal insufficiency (AI) require lifelong glucocorticoid replacement. They need to increase glucocorticoids during physical illness or major stressful situations and require parenteral hydrocortisone in the event of an adrenal crisis. Patients with AI have impaired quality of life and high mortality; approximately 1 in 6-12 patients are hospitalised at least once/year from a potentially preventable adrenal crisis. Adoption of self-management behaviours are crucial; these include adherence to medication, following "sick day rules" and associated behaviours that aid prevention and treatment of adrenal crisis such as symptom monitoring, having extra tablets, carrying a medical-alert ID and injection kit, and self-injecting when necessary. Current patient education is ineffective at supporting self-management behaviour change or reducing adrenal crisis-related hospitalisations. This research study aims to gain an in-depth understanding of the barriers and enablers to self-management for patients with AI and to develop an evidence-based digital self-management behaviour change intervention.

Methods

The study is conducted in accordance with the MRC Framework for developing complex interventions. Underpinned by the Behaviour Change Wheel (BCW), the Theoretical Domains Framework (TDF), and the Person-Based Approach, this research will be conducted in two phases: Phase 1 will involve a sequential qualitative/quantitative mixed-methods study involving focus group interviews followed by a cross-sectional survey with patients with AI recruited from patient advocacy groups and endocrine clinics in the UK. Phase 2 will develop the Support AI, a website-based digital behaviour change intervention (DBCI) informed by Phase 1 findings to support self-management for patients with AI. The most appropriate behaviour change techniques (BCTs) will be selected utilising a nominal group technique with an Expert Panel of 10-15 key stakeholders. The design of the Support AI website will be guided by the Person-Based Approach using an Agile iterative "think-aloud" technique with 12-15 participants over 3 usability testing iterations.

Conclusion

A theory- and evidence-based digital behaviour change intervention will be developed which will be tested in a feasibility randomised trial following completion of this study. The projected benefit includes cost-effective health care service (reduced hospitalisations and demand for specialist services) and improved health outcomes and quality of life for patients with AI.

Outcome of COVID-19 infections in patients with adrenal insufficiency and excess

BACKGROUND

Information on clinical outcomes of coronavirus disease 19 (COVID-19) infection in patients with adrenal disorders is scarce.

METHODS

A collaboration between the European Society of Endocrinology (ESE) Rare Disease Committee and European Reference Network on Rare Endocrine Conditions via the European Registries for Rare Endocrine Conditions allowed the collection of data on 64 cases (57 adrenal insufficiency (AI), 7 Cushing's syndrome) that had been reported by 12 centres in 8 European countries between January 2020 and December 2021.

RESULTS

Of all 64 patients, 23 were males and 41 females (13 of those children) with a median age of 37 and 51 years. In 45/57 (95%) AI cases, COVID-19 infection was confirmed by testing. Primary insufficiency was present in 45/57 patients; 19 were affected by Addison's disease, 19 by congenital adrenal hyperplasia and 7 by primary AI (PAI) due to other causes. The most relevant comorbidities were hypertension (12%), obesity (n = 14%) and diabetes mellitus (9%). An increase by a median of 2.0 (IQR 1.4) times the daily replacement dose was reported in 42 (74%) patients. Two patients were administered i.m. injection of 100 mg hydrocortisone, and 11/64 were admitted to the hospital. Two patients had to be transferred to the intensive care unit, one with a fatal outcome. Four patients reported persistent SARS-CoV-2 infection, all others complete remission.

CONCLUSION

This European multicentre questionnaire is the first to collect data on the outcome of COVID-19 infection in patients with adrenal gland disorders. It suggests good clinical outcomes in case of duly dose adjustments and emphasizes the importance of patient education on sick day rules.

Acute Adrenal Insufficiency Caused by Mental Stress in a Patient With Adrenocorticotropic Hormone Deficiency

In patients with chronic adrenal insufficiency, physical stress increases the requirement for glucocorticoid therapy. Although mental stress may cause acute adrenal insufficiency, it is debatable how patients should be treated when experiencing mental stress. Here, we report the case of a female patient with septo-optic dysplasia who had been treated for adrenocorticotropic hormone deficiency since infancy. After her grandfather died when she was 17 years old, she complained of nausea and stomach pain. Her symptoms failed to improve despite treatment with stress doses of oral hydrocortisone and self-administered glucagon injection. Her general condition improved after she began receiving continuous hydrocortisone and glucose infusions. Glucocorticoid stress doses should be given early if a patient is likely to experience mental stress.

Autoantibodies involved in primary and secondary adrenal insufficiency following treatment with immune checkpoint inhibitors

Primary and secondary adrenal insufficiency (AI) are commonly known immune-related adverse events following treatment with immune checkpoint inhibitors (ICIs), and are clinically relevant due to their morbidity and potential mortality. For this reason, upfront identification of patients susceptible for ICI-induced AI could be a step in improving patient's safety. Multiple studies have focused on the identification of novel biomarkers for ICI-induced AI, including autoantibodies, which may be involved in ICI-induced AI as a result of the T-cell-mediated activation of autoreactive B cells. This review highlights the currently described autoantibodies that may be involved in either primary [e.g. anti-21-hydroxylase, anti-17α-hydroxylase, anti-P450scc, anti-aromatic L-amino acid decarboxylase (AADC), anti-interferon (IFN)α and anti-IFNΩ] or secondary AI [e.g. anti-guanine nucleotide-binding protein G(olf) subunit alpha (GNAL), anti-integral membrane protein 2B (ITM2B), anti-zinc finger CCHC-type containing 8 (ZCCHC8), anti-pro-opiomelanocortin (POMC), anti-TPIT (corticotroph-specific transcription factor), anti-pituitary-specific transcriptional factor-1 (PIT-1) and others], and discusses the current evidence concerning their role as biomarker for ICI-induced AI. Standardized autoantibody measurements in patients (to be) treated with ICIs would be a clinically accessible and patient-friendly screening method to identify the patients at risk, and could change the management of ICI-induced AI.

The Changing Epidemiology of Adrenal Insufficiency: Iatrogenic Factors Predominate

Context

Adrenal insufficiency (AI)-related morbidity persists despite efforts to minimize its effect. Reasons for this are unknown and warrant examination.

Objective

This work aimed to investigate trends in AI hospitalizations and glucocorticoid (GC) replacement therapy use.

Methods

Data on hospitalizations for a principal diagnosis of AI and prescriptions for short-acting GCs between 2000 and 2019 were extracted from national repositories. Age-standardized admission and prescription rates were calculated using census data. Rates were compared over time overall and according to age, sex, and disease subtype.

Results

AI admissions increased by 62.0%, from 36.78/million to 59.59/million (trend P < .0001). Adrenal crisis (AC) admissions also increased, by 90.1% (from 10.73/million to 20.40/million; trend, P < .00001). These increases were more pronounced in the second decade. Prescriptions for short-acting GCs also increased (by 67.2%, from 2198.36/million in 2000/2001 to 3676.00/million in 2017/2018). Females had higher average admission rates and a greater increase in admission rates than males. Increased AI admissions were found in all age groups among females but only in men aged 70+ yrs. Secondary AI (SAI) admission rates increased by 91.7%, whereas admission rates for primary AI (PAI) remained unchanged.

Conclusion

The prevalence of AI and hospitalizations for this disorder (including ACs) have increased since 2000, with a greater increase occurring after 2010. Admission rates for SAI increased but PAI admissions remained stable. Possible causes include immunotherapies for malignancy, increased cranial imaging detecting pituitary tumors and their subsequent treatment, and increased use of low-dose, short-acting GC-replacement therapy.

Adrenal crisis in infants and young children with adrenal insufficiency: Management and prevention

BACKGROUND

Despite the optimization of replacement therapy, adrenal crises still represent life-threatening emergencies in many children with adrenal insufficiency.

OBJECTIVE

We summarized current standards of clinical practice for adrenal crisis and investigated the prevalence of suspected/incipient adrenal crisis, in relation to different treatment modalities, in a group of children with adrenal insufficiency.

RESULTS

Fifty-one children were investigated. Forty-one patients (32 patients <4 yrs and 9 patients >4 yrs) used quartered non-diluted 10 mg tablets. Two patients <4 yrs used a micronized weighted formulation obtained from 10 mg tablets. Two patients <4 yrs used a liquid formulation. Six patients >4 yrs used crushed non-diluted 10 mg tablets. The overall number of episodes of adrenal crisis was 7.3/patient/yr in patients <4yrs and 4.9/patient/yr in patients >4 yrs. The mean number of hospital admissions was 0.5/patient/yr in children <4 yrs and 0.53/patient/yr in children >4 yrs. There was a wide variability in the individual number of events reported. Both children on therapy with a micronized weighted formulation reported no episode of suspected adrenal crisis during the 6-month observation period.

CONCLUSION

Parental education on oral stress dosing and switching to parenteral hydrocortisone when necessary are the essential approaches to prevent adrenal crisis in children.

Quality of Life in Patients with Adrenal Insufficiency

Patients with adrenal insufficiency, despite standard glucocorticoid replacement therapy, continue to experience and report impaired self-perceived health status and quality of life. In this review, we will describe quality of life in this patient population, and summarize the determinants of quality of life, based on previous survey-based studies and clinical trials. In addition, some new emerging data during the still ongoing coronavirus disease pandemic are also reviewed in the present article.

Adrenal Crisis- An Adverse Reaction to Zoledronic Acid in a Patient with Primary Adrenal Insufficiency: A Case Report and Literature Review

Background/Objective

Adrenal crisis is a medical emergency and an acute complication of adrenal insufficiency (AI). It can be triggered by stressors such as infection, dehydration, trauma, or surgery.

Case Report

We present a case of a 70-year-old woman with a history of Addison's disease, who presented in adrenal crisis within 24 hours after receiving her first infusion of zoledronic acid. No trigger was identified after extensive evaluation, making infusion with zoledronic acid the most likely cause of adrenal crisis.

Discussion

Adverse reactions to medications can potentially trigger adrenal crisis. The present case report demonstrates that intravenous bisphosphonates can cause an acute phase reaction that may lead to adrenal crisis. Given the increased risk of osteoporosis in patients with AI there is an increased likelihood of prescription of intravenous bisphosphonates in this patient population.

Conclusion

Patients with AI undergoing infusion with zoledronic acid may require an increased dose of glucocorticoid prior to infusion and may need to undergo monitoring post infusion for possible adrenal crisis.

Clinical investigation of a unique type of hypothalamic adrenal insufficiency

Hypothalamic adrenal insufficiency (AI) is a rare but distinct type of AI. The leading cause of hypothalamic AI is a secondary side-effect of exogenous steroid intake, particularly in large amounts and/or long-term periods. The next cause would be the effect of the tumor in the hypothalamic lesions. We show here 9 cases of hypothalamic AI without any disorder on imagings and a history of steroid administration. All patients had general fatigue; 7 patients (77.8%) had a history of hypoglycemia; 5 patients (55.6%) had a history of hypotension. None of the patients had hyponatremia, hyperkalemia, or eosinophilia. Their morning plasma adrenocorticotropic hormone (ACTH) value was low at 8.5 ± 4.2 pg/mL, and serum cortisol value was low at 4.5 ± 1.3 µg/dL. All patients demonstrated normal responses during the corticotropin-releasing hormone loading (CRH) test but inadequate responses during the insulin tolerance test (ITT). After hydrocortisone replacement therapy, their morning plasma ACTH and serum cortisol values were significantly recovered (P < .05). Moreover, more than half of the patients were fine after discontinuing hydrocortisone replacement therapy. These results indicate that this unique type of hypothalamic AI has a curable clinical course making hydrocortisone replacement therapy a novel therapeutic option.

Adrenal crisis during pregnancy: Case report and obstetric perspective

Adrenal dysfunction (AD) and, in particular, adrenal crisis are uncommon events in pregnant women, but associated with significant maternal and fetal morbidity and mortality if untreated or undiagnosed. Adrenal crisis may be confused with the common symptoms of pregnancy: the obstetricians should be able to promptly diagnose and treat it in order to avoid the adverse outcomes regarding the mother and the fetus. For this reason, AD must be treated by an expert multidisciplinary team. We presented a case report of a young pregnant woman with adrenal crisis due to tuberculosis, cocaine abuse, and massive bilateral hemorrhage with symptoms of emesis, hypotension, sudden abdominal pain, and leukocytosis. The most common issues of diagnosis and treatment are discussed and analyzed. Finally, we performed a review of the literature regarding adrenal crisis and adrenal insufficiency (AI) in pregnancy in order to clarify the management of these diseases in obstetrics setting.

Diagnosis and Management of Adrenal Insufficiency and Adrenal Crisis in the Emergency Department

BACKGROUND

Adrenal insufficiency can result in significant patient morbidity and mortality, but due to the range of symptoms and variable clinical course and etiologies, it can be a challenging condition to diagnose and manage.

OBJECTIVE

This narrative review will discuss the evaluation of an adult patient at risk for a new diagnosis of adrenal insufficiency and the management of a patient with known or suspected adrenal insufficiency.

DISCUSSION

A new presentation of adrenal insufficiency can range from nonspecific, minor symptoms including fatigue, to a life-threatening adrenal crisis with hemodynamic instability. Due to the variety of signs and symptoms, the diagnosis is often missed. Those with known adrenal insufficiency are at risk for adrenal crisis, which may occur due to a variety of triggers. Initial evaluation includes assessment for the underlying etiology or concomitant condition, laboratory analysis, and imaging, when clinically indicated. Although not necessary for evaluation in the emergency department setting, the diagnosis is confirmed by specific testing such as the cosyntropin stimulation test. The mainstay of treatment in adrenal crisis is hydrocortisone, intravenous fluid, glucose repletion, and treatment of the underlying acute trigger.

CONCLUSIONS

Emergency clinicians must be prepared to recognize, evaluate, and manage those with known or suspected adrenal insufficiency or adrenal crisis.

Adrenal Crisis Presenting as Recurrent Encephalopathy Mimicking Autoimmune, Infectious Encephalitis, and Common Variable Immune Deficiency: A Case Report

INTRODUCTION

Adrenal crisis can present with life-threatening complications and mimic autoimmune or infectious encephalitis, and common variable immune deficiency (CVID). The literature regarding the neurological complications of adrenal crisis is limited and focuses on patients who present with hypotension and electrolyte abnormalities.

CASE REPORT

A 30-year-old man presented 3 times to our hospital with encephalopathy, fever, and left sided weakness with a history of multiple autoimmune diseases and prior hospitalizations for encephalopathy. During his first 2 admissions, he was normotensive and without electrolyte abnormalities. Extensive workup for infectious, paraneoplastic, seizure, metabolic, toxic, and vascular etiologies, and autoimmune encephalitis was negative. His exam returned to baseline with empiric steroid treatment, and he was discharged. He re-presented 2 months later with encephalopathy for a third admission. During this subsequent presentation, he had hyponatremia, low serum osmolality, elevated urine sodium, undetectable morning cortisol, and 21-α hydroxylase autoantibodies. A diagnosis of autoimmune adrenal insufficiency was established, he was treated with physiological doses of hydrocortisone and fludrocortisone, and improved rapidly to near baseline function. He has remained relapse-free at 4-year follow up. During all admissions, he was also found to have low immunoglobulin G levels and met criteria for CVID; however, his immunoglobin levels recovered with steroid replacement.

CONCLUSION

The reported patient demonstrated some of the neurological complications of adrenal crisis which can mimic other autoimmune conditions such as CVID. The neurologist should be aware that recurrent encephalopathy from adrenal insufficiency can occur regardless of hemodynamic or electrolyte changes on typical hospital metabolic panels.

Approach to the Patient With Glucocorticoid-induced Adrenal Insufficiency

Glucocorticoid-induced adrenal insufficiency is caused by exogenous glucocorticoid suppression of the hypothalamic-pituitary-adrenal axis and is the most prevalent form of adrenal insufficiency. The condition is important to diagnose given the risk of life-threatening adrenal crisis and impact on patients' quality of life. The diagnosis is made with a stimulation test such as the ACTH test. Until now, testing for glucocorticoid-induced adrenal insufficiency has often been based on clinical suspicion rather than routinely but accumulating evidence indicates that a significant number of cases will remain unrecognized. During ongoing oral glucocorticoid treatment or initially after withdrawal, ~50% of patients have adrenal insufficiency, but, outside clinical studies, ≤ 1% of patients have adrenal testing recorded. More than 70% of cases are identified during acute hospital admission, where the diagnosis can easily be missed because symptoms of adrenal insufficiency are nonspecific and overlap those of the underlying and intercurrent conditions. Treatment of severe glucocorticoid-induced adrenal insufficiency should follow the principles for treatment of central adrenal insufficiency. The clinical implications and thus indication to treat mild-moderate adrenal deficiency after glucocorticoid withdrawal has not been established. Also, the indication of adding stress dosages of glucocorticoid during ongoing glucocorticoid treatment remains unclear. In patients with established glucocorticoid-induced adrenal insufficiency, high rates of poor confidence in self-management and delayed glucocorticoid administration in the acute setting with an imminent adrenal crisis call for improved awareness and education of clinicians and patients. This article reviews different facets of glucocorticoid-induced adrenal insufficiency and discusses approaches to the condition in common clinical situations.

Interventions for the prevention of adrenal crisis in adults with primary adrenal insufficiency: a systematic review

Objective

The incidence of adrenal crisis (AC) remains high, particularly for people with primary adrenal insufficiency, despite the introduction of behavioural interventions. The present study aimed to identify and evaluate available evidence of interventions aiming to prevent AC in primary adrenal insufficiency.

Design

This study is a systematic review of the literature and theoretical mapping.

Methods

MEDLINE, MEDLINE in Process, EMBASE, ERIC, Cochrane CENTRAL, CINAHL, PsycINFO, the Health Management Information Consortium and trial registries were searched from inception to November 2021. Three reviewers independently selected studies and extracted data. Two reviewers appraised the studies for the risk of bias.

Results

Seven observational or mixed methods studies were identified where interventions were designed to prevent AC in adrenal insufficiency. Patient education was the focus of all interventions and utilised the same two behaviour change techniques, 'instruction on how to perform a behaviour' and 'pharmacological support'. Barrier and facilitator themes aiding or hindering the intervention included knowledge, behaviour, emotions, skills, social influences and environmental context and resources. Most studies did not measure effectiveness, and assessment of knowledge varied across studies. The study quality was moderate.

Conclusion

This is an emerging field with limited studies available. Further research is required in relation to the development and assessment of different behaviour change interventions to prevent AC.

Management of Acute Adrenal Insufficiency-Related Adverse Events in Children with Congenital Adrenal Hyperplasia: Results of an International Survey of Specialist Centres

INTRODUCTION

There is wide variation in reported rates of acute adrenal insufficiency (AI)-related adverse events (sick day episodes and adrenal crises) between centres. This study aimed to evaluate the level of consensus on criteria considered essential for defining and managing these events in children with Congenital Adrenal Hyperplasia.

METHODS

Active users of the International Congenital Adrenal Hyperplasia and International Disorders of Sex Development (I-CAH/I-DSD) Registries (n = 66), non-active users of I-CAH/I-DSD (n = 35), and the EuRRECa e-Reporting Registry (n = 10) were approached to complete an online survey.

RESULTS

Fifty-six centres from 27 countries responded to the survey; the response rates for the three groups were 42 (65%), 11 (31%), and 3 (30%), respectively. Steroid management plans, one to one patient education, and contact details of health care staff were provided by over 90% of centres in high-income countries. All 56 centres advised glucocorticoid stress dosing in the event of fever. Less common indications for sick day dosing included vaccination and mild afebrile intercurrent illness, recommended by 17 (30%) and 9 (16%) centres, respectively. The most frequently reported stress dosing regimens were tripling the total daily dose of hydrocortisone and administering 3 times daily and doubling or tripling the largest daily hydrocortisone dose depending on the nature of the trigger and administering 3 times daily, recommended by 24 (43%) and 21 (38%) centres, respectively. Vomiting was the most common indication for intramuscular hydrocortisone injection, reported by 34 (61%) centres. Over 50% of respondents indicated that essential clinical criteria for adrenal crisis should include fatigue and nausea or vomiting and over 60% indicated that hypotension, hyponatraemia, hyperkalaemia, and clinical improvement following parenteral glucocorticoids were essential criteria. In the event of an adrenal crisis, 47 (84%) reported that the majority of patients were admitted to hospital. For the management of an adrenal crisis, a bolus parenteral injection of hydrocortisone was the most frequently administered medication, reported by 50 (89%) centres.

CONCLUSION

Although there is variation in the definition and management of AI-related adverse events in children amongst centres, there is also a good level of consensus on specific aspects that can lead to greater benchmarking of care.

The ISAQ Score Does Not Predict Adrenal Crisis in Patients with Primary Adrenal Insufficiency

OBJECTIVE

This study aimed to investigate the ability of the immune system assessment questionnaire (ISAQ) to predict adrenal crisis (AC) and infectious events in patients with primary adrenal insufficiency (PAI).

DESIGN

This was a prospective single-centre study over three years.

METHODS

Patients answered the ISAQ at baseline and were seen every 4-6 months in the endocrine outpatient clinic. At each visit previous infectious periods which required an increase in daily glucocorticoid dosage and AC were reported and documented. Seventy-five patients with PAI (53 women; 43 patients with autoimmune PAI, 20 patients with salt-wasting congenital adrenal hyperplasia and 12 patients who underwent bilateral adrenalectomy) were analysed. Due to the COVID-19 pandemic and consecutive lockdown measures, the data were analysed separately for March 2018 to March 2020 (period 1), and March 2020 to March 2021 (period 2).

RESULTS

During period 1 the ISAQ score significantly correlated with the number of reported infectious events (r=0.351; p<0.01), but not during period 2 (r=0.059, p=0.613), in which the number of infectious events per patient-year significantly decreased (1.1±0.1 vs 0.4±0.1; p<0.001). The frequency of AC decreased from 8.8 to 2.4 per 100 patient-years between the two study periods. The ISAQ score was not different between patients with or without AC.

CONCLUSIONS

The ISAQ score does not identify patients prone to ACs. The COVID-19 pandemic and consecutive lockdown measures significantly diminished the frequency of infectious events and ACs.

Brain-immune axis regulation is responsive to cognitive behavioral therapy and mindfulness intervention: Observations from a randomized controlled trial in patients with Crohn's disease

BACKGROUND AND AIMS

Crohn's disease (CD) is a chronic inflammatory bowel disease associated with psychological stress that is regulated primarily by the hypothalamus-pituitary-adrenal (HPA) axis. Here, we determined whether the psychological characteristics of CD patients associate with their inflammatory state, and whether a 3-month trial of cognitive-behavioral and mindfulness-based stress reduction (COBMINDEX) impacts their inflammatory process.

METHODS

Circulating inflammatory markers and a wide range of psychological parameters related to stress and well-being were measured in CD patients before and after COBMINDEX. Inflammatory markers in CD patients were also compared to age- and sex-matched healthy controls (HCs).

RESULTS

CD patients exhibited increased peripheral low-grade inflammation compared with HCs, demonstrated by interconnected inflammatory modules represented by IL-6, TNFα, IL-17, MCP-1 and IL-18. Notably, higher IL-18 levels correlated with higher score of stress and a lower score of wellbeing in CD patients. COBMINDEX was accompanied by changes in inflammatory markers that coincided with changes in cortisol: changes in serum levels of cortisol correlated positively with those of IL-10 and IFNα and negatively with those of MCP-1. Furthermore, inflammatory markers of CD patients at baseline predicted COBMINDEX efficacy, as higher levels of distinct cytokines and cortisol at baseline, correlated negatively with changes in disease activity (by Harvey-Bradshaw Index) and psychological distress (global severity index measure) following COBMINDEX.

CONCLUSION

CD patients have a characteristic immunological profile that correlates with psychological stress, and disease severity. We suggest that COBMINDEX induces stress resilience in CD patients, which impacts their well-being, and their disease-associated inflammatory process.

Congenital Adrenal Hyperplasia-Current Insights in Pathophysiology, Diagnostics, and Management

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders affecting cortisol biosynthesis. Reduced activity of an enzyme required for cortisol production leads to chronic overstimulation of the adrenal cortex and accumulation of precursors proximal to the blocked enzymatic step. The most common form of CAH is caused by steroid 21-hydroxylase deficiency due to mutations in CYP21A2. Since the last publication summarizing CAH in Endocrine Reviews in 2000, there have been numerous new developments. These include more detailed understanding of steroidogenic pathways, refinements in neonatal screening, improved diagnostic measurements utilizing chromatography and mass spectrometry coupled with steroid profiling, and improved genotyping methods. Clinical trials of alternative medications and modes of delivery have been recently completed or are under way. Genetic and cell-based treatments are being explored. A large body of data concerning long-term outcomes in patients affected by CAH, including psychosexual well-being, has been enhanced by the establishment of disease registries. This review provides the reader with current insights in CAH with special attention to these new developments.

[Long-term morbidity in congenital adrenal hyperplasia]

Congenital adrenal hyperplasia (CAH) is one of the most common autosomal recessive disorders and is characterized by cortisol deficiency. The most common cause of CAH is a mutation in the CYP21A2 gene, resulting in 21-hydroxylase deficiency in the adrenal cortex. The lack of cortisol causes an increase in adrenocorticotropic hormone (ACTH), which in turn results in an excess of adrenal androgens. Aldosterone synthesis may also be impaired. The clinical manifestation of CAH depends on the residual activity of 21-hydroxylase and the subsequent lack of cortisol and adrenal androgen excess. While classic CAH is a potentially life-threatening condition, non-classic CAH is mild to asymptomatic. Therapy of classic CAH consists of glucocorticoid and mineralocorticoid substitution. Despite optimization of therapy, CAH still leads to increased morbidity and mortality in patients. The clinical consequences of androgen excess in affected women range from intrauterine virilisation of external genitalia in classic CAH patients to mild symptoms of hyperandrogenism in non-classic forms. Increased demand for cortisol during illness or physical and psychological stress situations can trigger life-threatening adrenal crises. As current glucocorticoid therapy cannot mimic the physiological circadian rhythm and is usually supraphysiological in dose to control androgen excess, therapy-associated long-term consequences such as decreased bone health and an increased cardiometabolic risk profile are common. The burden of the disease may also lead to impaired quality of life and mental health. For this reason, regular screening and follow-up of patients with CAH should be performed in specialized centers to detect and treat possible comorbidities at an early stage.

Susceptibility to Adrenal Crisis Is Associated With Differences in Cortisol Excretion in Patients With Secondary Adrenal Insufficiency

OBJECTIVE

To compare cortisol pharmacokinetics and pharmacodynamics mapped through several glucocorticoid sensitive pathways in patients on hydrocortisone substitution with or without an adrenal crisis.

DESIGN

A post-hoc analysis of a previously conducted randomized controlled trial in patients with secondary adrenal insufficiency examining the effects of 2 weight-adjusted hydrocortisone doses.

METHODS

Comparisons were primarily made on a hydrocortisone dose of 0.2-0.3 mg/kg/day for plasma cortisol and cortisone, 24-hour urinary steroid profile, the glucocorticoid sensitive tryptophan-kynurenine pathway, the renin-angiotensin-aldosterone system and aspects of quality of life. Variables of interest were also analyzed on the hydrocortisone dose of 0.4-0.6 mg/kg/day.

RESULTS

Out of 52 patients, 9 (17%) experienced at least one adrenal crisis (AC+ group) and 43 did not develop an adrenal crisis (AC- group) during an observation period of 10 years. 24-hour urinary excretion of cortisol and cortisone were lower in the AC+ group (0.05 [IQR 0.03; 0.05] vs. 0.09 [0.05; 0.12] µmol/24h, P=0.01and 0.13 [0.10; 0.23] vs. 0.24 [0.19; 0.38] µmol/24h, P=0.04, respectively). No differences in pharmacokinetics of cortisol were observed. Kynurenine concentrations were higher in the AC+ group (2.64 [2.43; 3.28] vs. 2.23 [1.82; 2.38] µmol/L, P=0.03) as was general fatigue (Z-scores 1.02 [-0.11; 1.42] vs. -0.16 [- 0.80; 0.28], P=0.04). On the higher hydrocortisone dose urinary excretion of cortisol and cortisone was still significantly lower between the AC- and AC + group. The differences in glucocorticoid sensitive variables disappeared.

CONCLUSION

Patients susceptible to an adrenal crisis demonstrated differences in cortisol and cortisone excretion as well as in pharmacodynamics when compared to patients who did not experience an adrenal crisis, suggesting a biological predisposition in certain patients for the development of an adrenal crisis.

Prevalence and Risk Factors for Adrenal Insufficiency in Patients with Multiple Myeloma Receiving Long-Term Chemotherapy including Corticosteroids: A Retrospective Cohort Study

Multiple myeloma (MM) is the second most common hematologic malignancy and requires long-term and high-dose corticosteroid-based chemotherapy. The aim of this study was to investigate the prevalence and clinical predictors of corticosteroid-associated adrenal insufficiency (AI) in patients with MM receiving long-term chemotherapy. This retrospective study included patients with MM who were administered corticosteroid-based chemotherapy and underwent a rapid adrenocorticotropic hormone (ACTH) stimulation test between 2005 and 2018. AI was determined by a peak cortisol value < 18 μg/dL after ACTH stimulation. Demographic, clinical, and laboratory parameters were evaluated, and the prevalence and clinical risk factors of AI were examined. Of 282 patients with MM who received corticosteroid-based chemotherapy, 142 patients (50.4%) were classified as having AI. There were no differences in age, sex, body mass index, comorbidities, and laboratory findings, including serum sodium levels between the AI and no-AI groups. In univariate analysis, the cumulative dose of corticosteroid (odds ratio (OR) = 0.99, 95% confidence interval (CI) 0.98-0.99; P = 0.020) and megestrol acetate use (OR = 2.63, 95% CI 1.48-4.67; P = 0.001) were associated with the occurrence of AI. Cumulative duration and cumulative dose per duration of corticosteroid use were not associated with the occurrence of AI. However, in the multivariate analysis, only megestrol acetate use was associated with an increased risk of AI (OR = 2.54, 95% CI 1.41-4.60; P = 0.002). Approximately 95.8% of patients with AI had suspicious symptoms or signs of AI. Although clinical symptoms and signs are usually nonspecific, symptomatic patients with MM receiving long-term corticosteroid therapy have sufficient potential for developing AI, particularly when receiving megestrol acetate. These findings can help alert clinicians to consider adrenal suppression following corticosteroid-based chemotherapy in patients with MM.

[New aspects of glucocorticoid substitution in adrenal insufficiency]

BACKGROUND

Appropriate glucocorticoid dose adjustment in specific situations significantly impacts quality of life and performance of patients with adrenal insufficiency. It is also pivotal for the prevention of adrenal crisis.

OBJECTIVES

Improving medical care for patients with adrenal insufficiency.

MATERIALS AND METHODS

Selective literature research focussing on the most recent studies.

RESULTS

Optimal glucocorticoid substitution aims at closely mimicking physiological fluctuations of cortisol levels. In recent years glucocorticoid preparations with modified pharmacokinetics have expanded the therapeutic arsenal. Adrenal crises occur with an incidence of 4.8-9.3 crises per 100 patient years. With a mortality of 0.5 per 100 patient years adrenal crisis is a life-threatening event. Therefore, it is of the utmost importance to adjust glucocorticoid dose in situations with increased cortisol demand in order to prevent as well as appropriately treat adrenal crisis.

CONCLUSIONS

To prevent life-threatening adrenal crisis, patients, their families and medical staff require training.

Patient periprocedural stress in cardiovascular medicine: friend or foe?

Stress, a disruption of homeostasis, is an unavoidable part of everyday life. In medical procedures, stress profoundly affects both operators and patients. Although the stress reaction has evolved to aid survival of physical trauma, it may also be harmful, by aggravating the baseline medical condition and/or creating new stress-related medical problems. Stress responses comprise several protective mechanisms that are particularly relevant in the clinical setting (e.g., a procoagulatory state and blood loss counteraction, preservation of blood perfusion pressure, prevention of hypoglycemia, enhanced immune response). Beneficial psychological effects prevent recurrence of traumatic memories, and promote patient compliance and positive lifestyle changes. In contrast, overt acute stress responses may lead to severe pathological conditions such as cytokine storm, post-traumatic stress disorder, takotsubo syndrome, deep venous thrombosis and pulmonary embolism, myocardial infarction, life-threatening arrhythmias and sudden cardiac death. There is also evidence that stress exposure may promote atherosclerosis and reduce long-term benefits from the intervention (increase in major adverse clinical events, in-stent restenosis, etc.). Insights into the role of stress on the operator’s performance have recently led to the introduction of counteractive measures such as simulation training. Conversely, very little is known about the effect of the patient’s periprocedural stress on the outcomes of cardiovascular procedures. Recent data show that the patient periprocedural stress affects the well-being of whole families. This review, focused on topics particularly relevant to cardiovascular interventions, provides a mechanistic insight into beneficial and harmful effects of periprocedural patient stress, including the array of available stress-relieving measures.

Adrenal crisis and mortality rate in adrenal insufficiency and congenital adrenal hyperplasia

Primary adrenal insufficiency (PAI) is characterized by the inability of the adrenal cortex to produce sufficient amounts of glucocorticoids and/or mineralocorticoids. Addison's disease (AD) and congenital adrenal hyperplasia (CAH) are the most frequent disorders in adults and children, respectively. Despite the diagnostic advances and the availability of glucocorticoid and mineralocorticoid replacements, adrenal crisis (AC) is still a potentially lethal condition contributing to the increased mortality, not only during the first year of life, but also throughout life. Failure in increasing glucocorticoid doses during acute stress, when greater amounts of glucocorticoids are required, can lead to AC and an increase morbimortality rate of PAI. Considering a mortality rate of 0.5 per 100 patient years, up to 1,500 deaths from AC are expected in Brazil in the coming decade, which represents an alarming situation. The major clinical features are hypotension and volume depletion. Nonspecific symptoms such as fatigue, lack of energy, anorexia, nausea, vomiting, and abdominal pain are common. The main precipitating factors are gastrointestinal diseases, other infectious disease, stressful events (e.g., major pain, surgery, strenuous physical activity, heat, and pregnancy), and withdrawal of glucocorticoid therapy. Suspected AC requires immediate therapeutic action with intravenous (iv) hydrocortisone, fluid infusion, monitoring support, and antibiotics if necessary. AC is best prevented through patient education, precocious identification and by adjusting the glucocorticoid dosage in stressor situations. The emergency card, warning about acute glucocorticoid replacement, has high value in reducing the morbidity and mortality of AC.

Challenging Diagnosis of Addison's Disease Presenting with Adrenal Crisis

Primary adrenal insufficiency, also known as Addison's disease, is a rare but potentially fatal condition resulting from the failure of the adrenal cortex to produce glucocorticoid and/or mineralocorticoid hormones. Unfortunately, the clinical manifestation of primary adrenal insufficiency is not specific and often progresses insidiously, resulting in late diagnosis, or in severe cases, life-threatening circulatory collapse. Adrenal insufficiency should be considered in patients with unexplained vascular collapse. We report the case of a woman who presented to the emergency ward with unexplainable shock that was later diagnosed as adrenal crisis due to Addison's disease. The presence of hyperpigmentation in patients with rapid progression of adrenal insufficiency suggests the diagnosis of Addison's disease presenting with adrenal crisis.

Peri-operative steroid management in the paediatric population

BACKGROUND

Patients with adrenal insufficiency are at risk of adrenal crisis, a potentially life-threatening emergency in the peri-operative period due to their attenuated ability to mount a cortisol response. There is a lack of standardization regarding peri-operative stress-dose glucocorticoids in paediatric clinical practice with the absence of agreed protocols. For the individual patient, the risk of adrenal crisis must be weighed against the potential adverse clinical outcomes associated with unnecessary or supra-physiologic glucocorticoid dosing in susceptible patients. Specific clinical concerns in the paediatric population include osteopenia, growth restriction and increased risk of cardiovascular disease in adulthood. This review aimed to identify and evaluate available literature in the field of peri-operative stress-dose glucocorticoids.

METHODS

A comprehensive literature search was conducted to construct a narrative review.

RESULTS

The outcome of this review identified that paediatric patients, unlike adults, do not show a graded response to surgical stress with implications for glucocorticoid stress dose regimens for general anaesthesia and less invasive surgical procedures. The studies highlight a lack of information on physiological steroid responses to stress situations and differences in the approach to glucocorticoid replacement strategies in the paediatric population.

CONCLUSION

The review identified there is a lack of high-quality paediatric-specific studies evaluating appropriate stress-dose glucocorticoid regimens in paediatric patients with or at risk of adrenal insufficiency. Further research is needed to establish clear evidence-based clinical guidelines for paediatric peri-operative practice regarding steroid stress dosing in adrenal insufficiency. Current knowledge would suggest that a balanced view of risks and benefits should be taken appropriate to the clinical context, to dictate peri-operative stress-dose glucocorticoids use that permits safe perioperative management.
