PRAP study-partial versus radical adrenalectomy in hereditary pheochromocytomas.

OBJECTIVE: Hereditary pheochromocytoma (hPCC) commonly develops bilaterally, causing adrenal insufficiency when standard treatment, radical adrenalectomy (RA), is performed. Partial adrenalectomy (PA) aims to preserve adrenal function, but with higher recurrence rates. This study compares outcomes of PA versus RA in hPCC. METHODS: Patients with hPCC due to pathogenic variants in RET, VHL, NF1, MAX, and TMEM127 from 12 European centers (1974-2023) were studied retrospectively. Stratified analysis based on surgery type and initial presentation was conducted. The main outcomes included recurrence, adrenal insufficiency, metastasis, and mortality. RESULTS: The study included 256 patients (223 RA, 33 PA). Ipsilateral recurrence rates were 9/223 (4%) after RA versus 5/33 (15%) after PA (P = 0.02). Metastasis and mortality did not differ between groups. Overall, 103 patients (40%) underwent bilateral adrenalectomy either synchronously or metachronously (75 RA, 28 PA). Of these, 46% developed adrenal insufficiency after PA.In total, 191 patients presented with initial unilateral disease, of whom 50 (26%) developed metachronous contralateral disease, most commonly in RET, VHL, and MAX. In patients with metachronous bilateral disease, adrenal insufficiency developed in 3/4 (75%) when PA was performed as the first operation followed by RA, compared to 1/7 (14%) when PA was performed as the second operation after prior RA (P = 0.09). CONCLUSION: In patients with hPCC undergoing PA, local recurrence rates are higher than after RA, but metastasis and disease-specific mortality are similar. Therefore, PA seems a safe method to preserve adrenal function in patients with hPCC, in cases of both synchronous and metachronous bilateral disease, when performed as a second operation.

Should we routinely assess hypothalamic-pituitary-adrenal axis in pediatric patients with Prader-Willi syndrome?

Background: It has been reported that central adrenal insufficiency (CAI) in pediatric patients (pts) with Prader-Willi syndrome (PWS) may be a potential cause of their sudden death. In addition, the risk of CAI may increase during treatment with recombinant human growth hormone (rhGH). Objective: To prevent both over- and undertreatment with hydrocortisone, we evaluated the prevalence of CAI in a large multicenter cohort of pediatric pts with PWS analyzing adrenal response in the low-dose ACTH test (LDAT) and/or the glucagon stimulation test (GST) and reviewing the literature. Methods: A total of 46 pts with PWS were enrolled to the study, including 34 treated with rhGH with a median dose of 0.21 mg/kg/week. LDAT was performed in 46 pts, and GST was carried out in 13 pts. Both tests were conducted in 11 pts. The tests began at 8:00 a.m. Hormones were measured by radioimmunoassays. Serum cortisol response >181.2 ng/mL (500 nmol/L) in LDAT and >199.3 ng/mL (550 nmol/L) in GST was considered a normal response. Additionally, cortisol response delta (the difference between baseline and baseline) >90 ng/mL and doubling/tripling of baseline cortisol were considered indicators of normal adrenal reserve. Results: Three GSTs were not diagnostic (no hypoglycemia obtained). LDAT results suggested CAI in four pts, but in two out of four pts, and CAI was excluded in GST. GST results suggested CAI in only one patient, but it was excluded in LDAT. Therefore, CAI was diagnosed in 2/46 pts (4.3%), 1 treated and 1 untreated with rhGH, with the highest cortisol values of 162 and 175 ng/dL, but only in one test. However, in one of them, the cortisol delta response was >90 ng/mL and peak cortisol was more than tripled from baseline. Finally, CAI was diagnosed in one patient treated with rhGH (2.2%). Conclusion: We present low prevalence of CAI in pediatric pts with PWS according to the latest literature. Therefore, we do not recommend to routinely screen the function of the hypothalamic-pituitary-adrenal axis (HPAA) in all pts with PWS, both treated and untreated with rhGH. According to a review of the literature, signs and symptoms or low morning ACTH levels suggestive of CAI require urgent and appropriate diagnosis of HPAA by stimulation test. Our data indicate that the diagnosis of CAI should be confirmed by at least two tests to prevent overtreatment with hydrocortisone.

The existence of adrenal insufficiency in patients with COVID-19 pneumonia.

Introduction: Infection with SARS-CoV-2 virus may result in long COVID, a syndrome characterized by symptoms such as dyspnea, cardiac abnormalities, cognitive impairment, and fatigue. One potential explanation for these symptoms is hypocortisolism. Objective: To evaluate the prevalence of hypocortisolism in patients with a history of COVID-19 pneumonia. Methods: Cross-sectional study of patients who were aged ≥18 years and had a 3-month history of radiography-confirmed COVID-19 pneumonia. Exclusion criteria included current or previous treatment with glucocorticoids and use of an oral contraceptive. Adrenal function was evaluated using a low dose (1ug) corticotropin stimulation test (CST). Serum cortisol levels were measured at 0, 30, and 60 minutes, and baseline plasma ACTH was also measured. Results: Of the 41 patients enrolled, the median age was 62 years, 17 (42%) were female, and all 41 (100%) had severe pneumonia at baseline. Eleven patients (27%) had hypocortisolism, as evidenced by peak cortisol of less than 402.81 nmol/l after low dose (1 µg) CST. Of these 11 patients, 10 (91%) had secondary hypocortisolism (median ACTH 6.27 pmol/L, range 4.98-9.95 pmol/L) and one had primary hypocortisolism (mean ACTH 32.78 pmol/L). Six of the 11 patients with hypocortisolism (54.5%) reported symptoms of persistent fatigue and 5 (45.5%) required regular glucocorticoid replacement. Conclusions: Our results suggest that hypocortisolism, predominantly caused by pituitary disruption, may emerge after SARS-CoV-2 infection and should be considered in patients with a history of COVID-19 pneumonia with or without clinical hypocortisolism.

Adrenal insufficiency in pediatric kidney transplantation recipients.

BACKGROUND: Immunosuppression of pediatric kidney transplant (PKT) recipients often includes corticosteroids. Prolonged corticosteroid exposure has been associated with secondary adrenal insufficiency (AI); however, little is known about its impact on PKT recipients. METHODS: This was a retrospective cohort review of PKT recipients to evaluate AI prevalence, risk factors, and adverse effects. AI risk was assessed using morning cortisol (MC) and diagnosis confirmed by an ACTH stimulation test. Potential risk factors and adverse effects were tested for associations with MC levels and AI diagnosis. RESULTS: Fifty-one patients (60.8% male, age 7.4 (IQR 3.8, 13.1) years; 1 patient counted twice for repeat transplant) were included. Patients at risk for AI (MC < 240 nmol/L) underwent definitive ACTH stimulation testing, confirming AI in 13/51 (25.5%) patients. Identified risk factors for AI included current prednisone dosage (p = .001), 6-month prednisone exposure (p = .02), daily prednisone administration (p = .002), and rejection episodes since transplant (p = .001). MC level (2.5 years (IQR 1.1, 5.1) post-transplant) was associated with current prednisone dosage (p < .001), 6-month prednisone exposure (p = .001), daily prednisone administration (p = .006), rejection episodes since transplant (p = .003), greater number of medications (ß = -16.3, p < .001), 6-month hospitalization days (ß = -3.3, p = .013), creatinine variability (ß = -2.4, p = .025), and occurrence of acute kidney injury (ß = -70.6, p = .01). CONCLUSION: Greater corticosteroid exposure was associated with a lower MC level and confirmatory diagnosis of AI noted with an ACTH stimulation test. Adverse clinical findings with AI included greater medical complexity and kidney function lability. These data support systematic clinical surveillance for AI in PKT recipients treated with corticosteroids.

Relationships between adrenal insufficiency and cardiovascular outcomes in patients with atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia.

BACKGROUND: Patients with Adrenal Insufficiency (AI) face elevated cardiovascular risks, but little remains known about arrhythmia outcomes in this context. METHOD: Analyzing the 2016-2019 Nationwide Inpatient Sample, we identified cases of Atrial Fibrillation, Atrial Flutter, and paroxysmal supraventricular tachycardia (PSVT) with a secondary diagnosis of AI. Mortality was the primary outcome while vasopressors and/or mechanical ventilation use, length of stay (LOS), and total hospitalization charges (THC) constituted secondary outcomes. Multivariate linear and logistic regression models were used to adjust for confounders. RESULTS: Among patients with Atrial Fibrillation, Atrial Flutter, and PSVT (N=1,556,769), 0.2% had AI. AI was associated with higher mortality (adjusted OR [aOR] 2.29, p=0.001), vasopressor and/or mechanical ventilation use (aOR 2.54, p<0.001), THC ($62,347 vs. $41,627, p<0.001) and longer LOS (4.4 vs. 3.2 days, p<0.001) compared to no AI. CONCLUSION: AI was associated with higher adverse outcomes in cases of Atrial Fibrillation, Atrial Flutter, and PSVT.

A retrospective review of the short Synacthen test in Queensland hospitals.

BACKGROUND: The short Synacthen test (SST) is widely used to investigate adrenal insufficiency, but it can be time-consuming, costly and labour-intensive to perform and is not without risk of adverse events. AIM: To review SST requesting patterns and practices across public hospitals in Queensland. METHODS: The electronic medical records of patients who underwent a SST with Pathology Queensland between January 2020 and December 2020 were reviewed to collect data regarding the indication for the test, the requesting speciality, SST results and any adverse events. RESULTS: Six hundred and fifty-two SSTs were identified, of which 363 individual patients were included in the analysis. The majority of the tests (n = 198, 54.5%) were performed in the inpatient setting. Endocrinology most commonly ordered SSTs (n = 188, 51.8%). The suspected aetiology of adrenal insufficiency was unclear in a large proportion of requests (n = 167, 46.0%). Static testing of morning cortisol prior to SST was performed in only 249 (68.6%) patients. Of 140 inpatients data, 17.9% (n = 25) showed a robust static cortisol of ≥400 nmol/L and were treated as having normal adrenal function, suggesting SST was unnecessary in these patients. Twenty-two (6.1%) patients had a documented adverse event occurring during or after the SST. CONCLUSIONS: There was wide variability in requesting patterns and practices for SSTs across Queensland. More than one in six SSTs could have been avoided if a static morning cortisol had been performed prior. Clinician education and the adoption of a structured referral form may improve testing practices.

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.

Critical Illness-Related Corticosteroid Insufficiency (CIRCI) After Pediatric Cardiac Surgery.

Although current studies do not support the routine use of corticosteroids after cardiopulmonary bypass in pediatric patients, there is incomplete understanding of the potential hemodynamic contribution of postoperative critical illness-related corticosteroid insufficiency in the intensive care unit. By reviewing the available studies and underlying pathophysiology of these phenomena in critically ill neonates, we can identify a subset of patients that may benefit from optimal diagnosis and treatment of receiving postoperative steroids. A suggested algorithm used at our institution is provided as a guideline for treatment of this high-risk population.

Spectrum of Adrenal Dysfunction in Hemoglobin E/Beta Thalassemia.

BACKGROUND: Adrenal insufficiency (AI) in hemoglobin E (HbE)/beta thalassemia, including evaluation of mineralocorticoid axis, had not been studied. AIMS AND OBJECTIVES: In this study, we attempted to evaluate the prevalence of AI in HbE/beta thalassemia and wanted to determine if the prevalence of AI varied according to severity of HbE/beta thalassemia and transfusion requirements. METHODS: In this observational, cross-sectional study, 104 patients with HbE/beta thalassemia were evaluated. Among them, 57 and 47 were transfusion dependent and non-transfusion dependent. According to Mahidol criteria, patients were classified into mild (n = 39), moderate (n = 39), and severe (n = 26) disease. Early morning (8 Am) serum cortisol, plasma ACTH, and plasma aldosterone, renin were measured. Patients with baseline cortisol of 5 to 18 µg/dL underwent both 1 µg and 250 µg short Synacthen test. According to these results, patients were classified as having either normal, subclinical, or overt (primary/secondary) adrenal dysfunction. RESULTS: Adrenal insufficiency was found in 41% (n = 43). Among them 83.7% (n = 34) had primary AI and 16.3% (n = 9) had secondary AI. Thirty-three patients (31%) with normal or elevated ACTH and with low or normal aldosterone with high renin were diagnosed as having subclinical AI. There was no difference in prevalence of AI between transfusion dependent and non-transfusion dependent (P = .56) nor was there was any difference in prevalence of AI according to disease severity (P = .52). CONCLUSION: Adrenal insufficiency is common in HbE/beta thalassemia and is independent of transfusion dependency and disease severity.

Increased risk of hospitalization, intensive care and death due to COVID-19 in patients with adrenal insufficiency: A Swedish nationwide study.

BACKGROUND: Patients with adrenal insufficiency (AI) have excess morbidity and mortality related to infectious disorders. Whether patients with AI have increased morbidity and mortality from COVID-19 is unknown. METHODS: In this linked Swedish national register-based cohort study, patients with primary and secondary AI diagnosis were identified and followed from 1 January 2020 to 28 February 2021. They were compared with a control cohort from the general population matched 10:1 for age and sex. The following COVID-19 outcomes were studied: incidence of COVID-19 infection, rates of hospitalization, intensive care admission and death. Hazard ratios (HR) with 95% confidence intervals (95% CI) adjusted for socioeconomic factors and comorbidities were estimated using Cox regression analysis. RESULTS: We identified 5430 patients with AI and 54,300 matched controls: There were 47.6% women, mean age was 57.1 (standard deviation 18.1) years, and the frequency of COVID-19 infection was similar, but the frequency of hospitalization (2.1% vs. 0.8%), intensive care (0.3% vs. 0.1%) and death (0.8% vs. 0.2%) for COVID-19 was higher in AI patients than matched controls. After adjustment for socioeconomic factors and comorbidities, the HR (95% CI) was increased for hospitalization (1.96, 1.59-2.43), intensive care admission (2.76, 1.49-5.09) and death (2.29, 1.60-3.28). CONCLUSION: Patients with AI have a similar incidence of COVID-19 infection to a matched control population, but a more than twofold increased risk of developing a severe infection or a fatal outcome. They should therefore be prioritized for vaccination, antiviral therapy and other appropriate treatment to mitigate hospitalization and death.

Serum cortisol level to screen for significant hypothalamic-pituitary-adrenal axis suppression in patients receiving multiple steroid injections.

BACKGROUND: Morning serum cortisol level (mSCL) is a practical screening tool for hypothalamic-pituitary-adrenal (HPA) axis suppression and has been used to assess for duration of cortisol deficiency after epidural and peripheral glucocorticoid injections. More evidence is needed to establish the utility of mSCL in patients undergoing repeat injections with increasing cumulative glucocorticoid equivalent dose (CGED) that could place them at higher risk of HPA axis suppression. OBJECTIVES: To estimate the prevalence of spine injection candidates with significant HPA axis suppression (sigAS), to understand the correlation between 12 months of CGED and the presence of sigAS based on the timing of mSCL collection after the most recent glucocorticoid injection (within 6 weeks or between 6 weeks and 12 months), and to investigate demographic and clinical factors relating to sigAS. METHODS: Retrospective chart review of patients scheduled for spine injection who had an associated mSCL and documented histories of prior glucocorticoid injections. The steroid name, dose, type, and procedure location were recorded for each injection that occurred within 12 months before mSCL. CGED was calculated from standard glucocorticoid equivalent conversion factors. RESULTS: SigAS was present in 7.8% to 22% of the analysis cohorts. There was no association found between CGED and sigAS regardless of timing of mSCL. There was a trend toward lower mSCL and sigAS with increasing CGED. There were no significant relationships found between sigAS and overall demographic or clinical factors. CONCLUSIONS: A 3-fold reduction in the rate of sigAS was noted 6 weeks after the most recent steroid injection. Using mSCL provides a template to investigate the impact of CGED and the best timing for mSCL collection in order to define a more practical guideline to identify patients at higher risk of sigAS earlier and plan for future spine injections.

Morbidity in Patients with Chronic Adrenal Insufficiency - Cardiovascular Risk Factors and Hospitalization Rate Compared to Population Based Controls.

Patients with adrenal insufficiency (AI) have been found to have increased cardiovascular morbidity, partly associated with nonphysiologic glucocorticoid replacement. We included two separate cohorts (cohort 1 n=384 patients, cohort 2 n=180 patients) of patients with chronic primary and secondary AI under standard replacement therapy and compared them to two age- and sex-matched population-based studies (SHIP-TREND/DEGS). Odds ratios with 95% CI for hypertension, hyperlipidemia/HLP, type 2 diabetes/T2DM, obesity, and hospitalization with adjustment for confounders were evaluated by logistic regression. Patient cohort 1 had significantly lower ORs for obesity [0.4 (0.3-0.6), p<0.001] and hypertension [0.5 (0.3-0.6), p<0.001] compared to SHIP-TREND and for obesity [0.7 (0.5-0.9), p=0.01], hypertension [0.4 (0.3-0.5), p<0.001] and HLP [0.4 (0.3-0.6), p<0.001] compared to DEGS. In cohort 2, ORs were significantly lower for HLP compared to both SHIP-TREND [0.4 (0.2-0.7), p=0.001] and DEGS [0.3 (0.2-0.5), p<0.001] and for hypertension [0.7 (0.4-0.9), p=0.04] compared to SHIP-TREND. In patients with SAI from cohort 2, ORs for DM2 [2.5 (1.3-4.9) p=0.009], hypertension [2.5 (1.4-4.5), p=0.002] and obesity [1.9 (1.1-3.1), p=0.02] were significantly higher compared to DEGS, whereas ORs for HLP were significantly lower compared to both SHIP [0.3 (0.1-0.6), p=0.002] and DEGS [0.3 (0.1-0.6), p<0.001]. In most of our AI patients treated with conventional glucocorticoid doses, the risk for T2DM, obesity, hypertension, and HLP was not increased. The number of hospitalizations was significantly higher in AI patients compared to controls, which might reflect increased susceptibility but also a more proactive management of concomitant diseases by physicians and patients.

Postpartum acute adrenal insufficiency of early-onset Sheehan syndrome: A case series study in a single center.

AIM: To identify the symptoms and relevant factors associated with acute adrenal insufficiency of early-onset Sheehan syndrome. METHODS: We retrospectively reviewed the charts of 125 women admitted to our intensive care unit because of postpartum hemorrhage between January 2011 and December 2021. Three women developed acute adrenal insufficiency. We investigated the total blood loss, shock status, consciousness level upon arrival, and intensive care provided to the women. We also analyzed the symptoms and laboratory data that led to the diagnosis of acute adrenal insufficiency. Continuous variables were presented by median (minimum-maximum). RESULTS: The medians and ranges of age, total blood loss, and shock index [heart rate/systolic blood pressure] on admission were 33.1 (17.2-45.3) years, 3351 (595-20 260) g, and 0.94 (0.55-2.94), respectively. Seven women were older than 40 years, 28 experienced >5000 g blood loss, 17 had shock index >1.5, 27 had impaired consciousness upon arrival, and 15 underwent hysterectomy. Women who developed acute adrenal insufficiency were <40 years old and had a bleeding volume of over 5000 g, impaired consciousness upon arrival, and had undergone hysterectomy. They had experienced lactation failure, presented with hyponatremia-related symptoms on postpartum days 8-9, experienced general malaise, headache, and impaired consciousness, and showed severe hyponatremia. CONCLUSIONS: Massive postpartum hemorrhage over 5000 g, impaired consciousness upon arrival, and hysterectomy as a hemostatic measure were relevant factors associated with acute adrenal insufficiency of early-onset Sheehan syndrome. Hyponatremia-related symptoms occurring after lactation failure are indicative of the onset of acute adrenal insufficiency.

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.

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 11ß-hydroxysteroid dehydrogenase 1 (HSD11B1) and 11ß-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.

Factors underlying a disproportionate increase in hospital admissions for adrenal insufficiency in women aged 20-29 years.

Since the year 2000, admissions for adrenal insufficiency (AI) and adrenal crises (AC) have shown a particular increase in young adult females. We examined data on acute non-surgical hospitalisations for AI/AC from New South Wales, Australia, to determine relevant factors that may have contributed to this increase. Data were analysed to ascertain associations between various comorbid psychosocial issues, identified by relevant ICD-10-AM codes in each record, and ACs. From 2005 to 2021. There were 877 admissions for an acute non-surgical illness in this age group. The average admission rate for females [63.5/million/year] was almost twice that for males [34.0/million/year] (p<0.01), as was the average female AC admission rate [14.7/million/year] relative to that in males [6.75/million/year] (p=NS). Infection was present in 41.6% (n=365) of the admissions and Type 1 diabetes mellitus was present in 12.2% (n=107). Overall, psychosocial factors were considered by the senior clinician to have contributed to the illness episode in 22.1% of all admissions and 29.0% of AC admissions. Having one or more psychosocial problems was associated with an AC in females (37.4%, n=49, in those having an AC, p<0.001) but not males. Females with an AC also had a higher mean composite psychosocial, psychiatric and drug/alcohol score [0.47 (0.67)] than females without an AC [0.32 (0.62) p<0.05]. No comparable associations were found in male patients. An increase in the rates of hospitalisations that included a code for at least one psychosocial problem was highly correlated with increases in admission rates for both ACs (r=0.82, p<0.001) and all AI (r=0.98, p<0.001) in females but there was no such relationship in males. This new evidence suggests that psychosocial factors may play an important role in ongoing rates of ACs in treated AI (incidence approximately 6-8 ACs/100PY) particularly in young adult females. In order to minimize AC episodes, all barriers to self-management need exploration on an individual patient basis and with regard to the patient population as a whole.

Statin treatment is not associated with an increased risk of adrenal insufficiency in real-world setting.

Introduction: Statins could reduce the synthesis of steroid hormones, thereby could cause adrenal insufficiency. We investigated this risk in a large nationwide database. Methods: We conducted a nested case-control study using a cohort of individuals affiliated to the French health insurance system in 2010, ≥18y and without adrenal insufficiency history. Each case had a first event of adrenal insufficiency between 2015 and 2017 and was matched to up to ten controls on age, sex, and prior treatment with corticosteroids. Statin exposure was measured over the five years preceding the index date, considering a six-month censoring lag-time. Association was estimated using a conditional logistic regression adjusted for confounders included in a disease risk score. Analyses were stratified on age, sex and corticosteroid history of use. Results: 4 492 cases of adrenal insufficiency were compared with 44 798 controls (median age 66y, 58% women), of which 39% vs. 33% were exposed to statins, respectively. No association between statin use and adrenal insufficiency was found when adjusting the model for confounders (adjusted odds ratio 0.98; 95% confidence interval 0.90-1.05). These results were consistent regardless of the exposure definition and stratifications considered. Conclusion: Statin-related adrenal insufficiency risk, if any, seems to be very limited and does not compromise the benefit of statin treatment.

Risk factors that are associated with adrenal insufficiency among patients with fever of unknown origin.

BACKGROUND: Adrenal insufficiency is one of the causes of fever of unknown origin (FUO). The purpose of this study is to find out risk factors that are associated with adrenal insufficiency in FUO patients. METHODS: This study was conducted retrospectively in a tertiary hospital with 846 beds in South Korea. All adult inpatients (age ≥19 years) who have requested a consult with the department of infectious disease for FUO between 1 July 20191 July 2019 and 30 June 202030 June 2020 were included in the study. Among them, those who underwent an adrenocorticotropic hormone (ACTH) stimulation test and had a fever of 37.8°C or higher within 48 hours of the ACTH stimulation test were finally included in the study subjects. RESULTS: A total of 202 FUO patients were enrolled and 61 (30.1%) were finally diagnosed with adrenal insufficiency. In a multivariate analysis, use of immunosuppressant within 3 months (OR 6.06, 95% CI 1.82-20.13, P = 0.003), use of corticosteroid within 3 months (OR 8.23, 95% CI 1.35-50.17, P = 0.022), sodium ≥ 136.7 (OR 3.43, 95% CI 1.49-7.88, P = 0.004), and calcium ≥ 8.4 (OR 0.31, 95% CI 0.14-0.71, P = 0.005) were proven to be factors associated with adrenal insufficiency in FUO patients. CONCLUSION: In conclusion, 30.1% of FUO patients were diagnosed with adrenal insufficiency. The risk factors that are associated with adrenal insufficiency in FUO patients were immunosuppressive prescription or systemic steroid prescription within 3 months, or with sodium ≥ 136.7 or calcium < 8.4.

COVID-19 pandemic and adrenals: deep insights and implications in patients with glucocorticoid disorders.

PURPOSE: Coronavirus disease-19 (COVID-19) has spread throughout the world. It was initially defined as a potentially severe syndrome affecting the respiratory tract, but it has since been shown to be a systemic disease with relevant extrapulmonary manifestations that increase mortality. The endocrine system has been found to be vulnerable to COVID-19 infection. The current review aims to evaluate the available data on the impact of COVID-19 infection and treatment, as well as COVID-19 vaccines, on adrenal gland function, particularly in patients with GC disorders. METHODS: A thorough search of published peer-reviewed studies in PubMed was performed using proper keywords. RESULTS: Adrenal viral tropism and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication in the adrenal glands have been demonstrated, and adrenal insufficiency (AI) is a rare, but potentially severe complication in COVID-19 disease, whose recognition can be difficult if only for the empirical treatments administered in the early stages. Glucocorticoid (GC) treatment have had a pivotal role in preventing clinical deterioration in patients with COVID-19, but long-term GC use may increase COVID-19-related mortality and the development of iatrogenic AI. Patients with GC disorders, especially AI and Cushing's syndrome, have been identified as being at high risk of COVID-19 infection and complications. Published evidence suggests that AI patient awareness and proper education may help adjust GC replacement therapy appropriately when necessary, thereby reducing COVID-19 severity. The COVID-19 pandemic has had an impact on AI management, particularly in terms of adherence to patients' care plans and self-perceived challenges. On the other hand, published evidence suggests that the clinical course of COVID-19 may be affected by the severity of hypercortisolism in patients with CS. Therefore, to ameliorate the risk profile in these patients, cortisol levels should be adequately controlled, along with careful monitoring of metabolic and cardiovascular comorbidities. To date, the COVID-19 vaccine remains the only available tool to face SARS-CoV-2, and it should not be treated differently in patients with AI and CS. CONCLUSION: SARS-CoV-2 infection has been linked to adrenal damage and AI is a rare complication in COVID-19 disease, requiring prompt recognition. Educational efforts and patient awareness may reduce COVID-19 severity in patients with AI. Control of cortisol levels and monitoring of complications may improve the clinical course of COVID-19 in patients with CS.

Critical Illness-Related Corticosteroid Insufficiency (CIRCI) Among Patients with COVID-19 at a Tertiary Hospital: Clinical Characteristics and Outcomes.

Objectives: Among critically ill patients, there is usually impairment of the hypothalamic-pituitary-adrenal axis, leading to a condition known as critical illness-related corticosteroid insufficiency (CIRCI). This investigation aims to determine the incidence of and characterize CIRCI among patients with COVID-19 as well as to analyze the outcomes of these critically ill patients. Methodology: This is a single-center, retrospective cohort study that investigated the occurrence of CIRCI among critically ill patients infected with COVID-19. Results: In this cohort, there were 145 COVID-19-positive patients with refractory shock, which reflects that 22.94% of the COVID-19 admissions have probable CIRCI.Patients who were given corticosteroids were found to have statistically significant longer median days on a ventilator (p=0.001). However, those on the corticosteroid arm were at higher risk of morbidity and mortality and a greater proportion had organ dysfunction. Multivariable logistic regression analysis revealed that SOFA score was a significant predictor of mortality in CIRCI (p=0.013). Conclusion: CIRCI has a unique presentation among patients with COVID-19 because of the presence of a high level of inflammation in this life-threatening infection. It is possibly a harbinger of a markedly increased risk of mortality in these patients.
