Abstract Objective The aim of this study is to assess whether clinical and imaging characteristics are associated with the hormonal subtype, growth, and adrenalectomy for incidental adrenal cortical adenomas (ACAs). Design This is a single-center cohort study. Methods Consecutive adult patients with incidental ACA were diagnosed between 2000 and 2016. Results Of the 1516 patients with incidental ACA (median age 59 years, 62% women), 699 (46%) had nonfunctioning adenomas (NFAs), 482 (31%) had mild autonomous cortisol secretion (MACS), 62 (4%) had primary aldosteronism (PA), 39 (3%) had Cushing syndrome, 18 (1%) had PA and MACS, and 226 (15%) had incomplete work-up. Age, sex, tumor size, and tumor laterality, but not unenhanced computed tomography Hounsfield units (HU), were associated with hormonal subtypes. In a multivariable analysis, ≥1 cm growth was associated with younger age (odds ratio [OR] = 0.8 per 5-year increase, P = .0047) and longer imaging follow-up (OR = 1.2 per year, P < .0001). Adrenalectomy was performed in 355 (23%) patients, including 38% of MACS and 15% of NFA. Adrenalectomy for NFA and MACS was more common in younger patients (OR = 0.79 per 5-year increase, P = .002), larger initial tumor size (OR = 2.3 per 1 cm increase, P < .0001), ≥1 cm growth (OR = 15.3, P < .0001), and higher postdexamethasone cortisol (OR = 6.6 for >5 vs <1.8 μg/dL, P = .002). Conclusions Age, sex, tumor size, and laterality were associated with ACA hormonal subtype and can guide diagnosis and management. Tumor growth was more common with younger age and longer follow-up. Unenhanced HU did not predict hormonal subtype or growth. Adrenalectomy for MACS and NFA was mainly performed in younger patients with larger tumor size, growth, and elevated postdexamethasone cortisol.

Abstract Objective Adrenal adenomas are commonly encountered in clinical practice. To date, population-based data on their impact on cognition, mental health, and sleep are lacking. We aimed to study possible associations between adrenal adenomas and dementia, psychiatric or sleep disorders. Design Population-based cohort study, Olmsted County, MN, 1995-2017. Methods Patients with adrenal adenoma and absent overt hormone excess were age- and sex-matched 1:1 to a referent person without adrenal adenoma. Outcomes were baseline and incident diagnoses of dementia, psychiatric or sleep disorders, assessed using ICD codes. Results Of 1004 patients with adrenal adenomas, 582 (58%) were women, and median age at diagnosis was 63 years. At baseline, and after adjusting for age, sex, education, BMI, and tobacco use, patients with adenoma had higher odds of depression (adjusted odds ratio, aOR: 1.3, 95% CI, 1.1-1.6), anxiety (aOR: 1.4, 95% CI, 1.1-1.8), and substance abuse (aOR: 2.4, 95% CI, 1.7-3.4) compared to referents. During a median follow-up of 6.8 years, and after adjusting for age, sex, socioeconomic status, BMI, tobacco, and substance abuse, patients demonstrated a higher risk of psychiatric and sleep disorders [adjusted hazard ratio (95% CI)]: depression [1.7 (1.3-2.2)], anxiety [1.4, CI (1.1-1.7)], insomnia [1.4 (1.0-1.9)], sleep-related breathing disorders [1.5 (1.1-1.9)], hypersomnias [2.1 (1.0-4.2)], parasomnias [2.1 (1.0-4.2)], and sleep-related movement disorders [1.5 (1.0-2.1)], but not dementia. Conclusions Patients with adenomas demonstrate a higher incidence of psychiatric and sleep disorders, possibly due to the underlying subtle increase in cortisol secretion.

Abstract Objective Glucocorticoid withdrawal syndrome (GWS) is a scarcely studied phenomenon that complicates the recovery following surgical remission of hypercortisolism. We aimed to characterize the presence and trajectory of glucocorticoid withdrawal symptoms in the postoperative period and to determine presurgical predictors of GWS severity. Design Longitudinal observational study. Methods Glucocorticoid withdrawal symptoms were prospectively evaluated weekly for the first 12 weeks following surgical remission of hypercortisolism. Quality of life (CushingQoL and Short-Form-36) and muscle function (hand grip strength and sit-to-stand test) were assessed at the baseline and at 12 weeks after surgery. Results Prevalent symptoms were myalgias and arthralgias (50%), fatigue (45%), weakness (34%), sleep disturbance (29%), and mood changes (19%). Most symptoms persisted, while myalgias, arthralgias, and weakness worsened during weeks 5-12 postoperatively. At 12 weeks after surgery, normative hand grip strength was weaker than at baseline (mean Z-score delta −0.37, P = .009), while normative sit-to-stand test performance improved (mean Z-score delta 0.50, P = .013). Short-Form-36 Physical Component Summary score worsened (mean delta −2.6, P = .015), but CushingQoL score improved (mean delta 7.8, P < .001) at 12 weeks compared to baseline. Cushing syndrome (CS) clinical severity was predictive of postoperative GWS symptomology. Conclusion Glucocorticoid withdrawal symptoms are prevalent and persistent following surgical remission of hypercortisolism with baseline CS clinical severity predictive of postoperative GWS symptom burden. Differential changes observed in muscle function and quality of life in the early postoperative period may reflect the competing influences of GWS and recovery from hypercortisolism.

Abstract Objective Prospective data on determinants of muscle strength impairment and quality of life in patients with various subtypes and severity of endogenous hypercortisolism are lacking. Design Single-center cross-sectional study, 2019 to 2022. Methods Patients with Cushing syndrome (CS) and mild autonomous cortisol secretion (MACS) were assessed with clinical and biochemical severity scores, muscle function (nondominant hand grip strength and sit-to-stand test), and quality of life (Short Form-36 [SF36] and CushingQoL). Referent subjects were recruited from the local population undergoing abdominal imaging for reasons other than suspected adrenal disorder. Results Of 164 patients, 81 (49%) had MACS, 14 (9%) had adrenal CS, 60 (37%) had pituitary CS, and 9 (5%) had ectopic CS. Median age was 53 years (interquartile range: 42-63 years), and 126 (77%) were women. The SF36 mental component score was similarly low in patients with MACS vs CS, but physical component score was lower in CS when compared to MACS (mean of 34.0 vs 40.5, P = .001). Compared to MACS, patients with CS had lower scores on the standardized CushingQoL (mean of 47.1 vs 34.2, P < .001). Compared to referent subjects, patients with MACS demonstrated reduced muscle strength, similar to patients with CS (mean sit to stand Z-score of −0.47 vs −0.54, P = .822). Clinical severity (r = −0.22, P = .004) but not biochemical severity was associated with sit-to-stand test performance. Conclusions Both patients with overt CS and MACS demonstrate reduced muscle strength and low quality of life. The clinical severity score utilized is associated with both physical and psychosocial components of CushingQoL and with the physical component of SF36.

Background Accumulating evidence suggests that primary aldosteronism (PA) is associated with several features of the metabolic syndrome, in particular with obesity, type 2 diabetes mellitus, and dyslipidemia. Whether these manifestations are primarily linked to aldosterone-producing adenoma (APA) or bilateral idiopathic hyperaldosteronism (IHA) remains unclear. The aim of the present study was to investigate differences in metabolic parameters between APA and IHA patients and to assess the impact of treatment on these clinical characteristics. Methods We conducted a retrospective multicenter study including 3566 patients with APA or IHA of Caucasian and Asian origin. We compared the prevalence of metabolic disorders between APA and IHA patients at the time of diagnosis and 1-year post-intervention, with special references to sex differences. Furthermore, correlations between metabolic parameters and plasma aldosterone, renin, or plasma cortisol levels after 1 mg dexamethasone (DST) were performed. Results As expected, APA patients were characterized by higher plasma aldosterone and lower serum potassium levels. Only female IHA patients demonstrated significantly worse metabolic parameters than age-matched female APA patients, which were associated with lower cortisol levels upon DST. One-year post-intervention, female adrenalectomized patients showed deterioration of their lipid profile, when compared to patients treated with mineralocorticoid receptor antagonists. Plasma aldosterone levels negatively correlated with the BMI only in APA patients. Conclusions Metabolic alterations appear more prominent in women with IHA. Although IHA patients have worse metabolic profiles, a correlation with cortisol autonomy is documented only in APAs, suggesting an uncoupling of cortisol action from metabolic traits in IHA patients.

Abstract Context Current evidence on determinants of quality of life (QoL) in patients with adrenal insufficiency (AI) is limited. Objective This work aimed to identify the determinants of QoL in different subtypes of AI. Methods This multicenter cross-sectional survey study was conducted using a patient-centered questionnaire, the Short Form-36. Results Of 529 participants, 223 (42.2%) had primary AI, 190 (35.9%) had secondary AI, and 116 (21.9%) had glucocorticoid-induced AI. Median age was 58 years (interquartile range: 43-68 years) and 342 (64.8%) were women. In multivariable analyses, patients were more likely to report worse physical scores if they were women (odds ratio [OR]: 3.3; 95% CI, 1.8-6.0), had secondary AI or glucocorticoid-induced AI (OR: 2.5; 95% CI, 1.4-4.3), had shorter duration of AI (OR: 2.0; 95% CI, 1.1-3.6), were treated with more than 25 mg hydrocortisone equivalent daily (OR: 2.3; 95% CI, 1.2-4.6), had more comorbidities related to glucocorticoid excess (OR: 2.3; 95% CI, 1.3-4.0), reported a higher financial burden from AI (OR: 2.1; 95% CI, 1.3-3.6), and reported difficulties with AI management (OR: 2.5; 95% CI, 1.2-5.2). Women (OR: 2.1; 95% CI, 1.08-4.0), shorter duration of AI (OR: 2.4; 95% CI, 1.4-4.3), higher financial burden (OR: 2.3; 95% CI, 1.3-4.0), difficulties with AI management (OR: 2.6; 95% CI, 1.4-4.9), and lack of family support (OR: 9.1; 95% CI, 2.3-33.3) were associated with worse mental component scores. Conclusion In patients with AI, QoL could be improved by addressing certain determinants, such as avoiding GC overreplacement, providing in-depth education on self-management, offering more comprehensive insurance coverage, and ensuring better family support.

Abstract Context While adrenal adenomas have been linked with cardiovascular morbidity in convenience samples of patients from specialized referral centers, large-scale population-based data are lacking. Objective To determine the prevalence and incidence of cardiometabolic disease and assess mortality in a population-based cohort of patients with adrenal adenomas. Design Population-based cohort study. Setting Olmsted County, Minnesota, USA. Patients Patients diagnosed with adrenal adenomas without overt hormone excess and age- and sex-matched referent subjects without adrenal adenomas. Main outcome measure Prevalence, incidence of cardiometabolic outcomes, mortality. Results (Adrenal adenomas were diagnosed in 1004 patients (58% women, median age 63 years) from 1/01/1995 to 12/31/2017. At baseline, patients with adrenal adenomas were more likely to have hypertension [adjusted odds ratio (aOR) 1.96, 95% CI 1.58-2.44], dysglycemia (aOR 1.63, 95% CI 1.33-2.00), peripheral vascular disease (aOR 1.59, 95% CI 1.32-2.06), heart failure (aOR 1.64, 95% CI 1.15-2.33), and myocardial infarction (aOR 1.50, 95% CI 1.02-2.22) compared to referent subjects. During median follow-up of 6.8 years, patients with adrenal adenomas were more likely than referent subjects to develop de novo chronic kidney disease [adjusted hazard ratio (aHR) 1.46, 95% CI 1.14-1.86], cardiac arrhythmia (aHR 1.31, 95% CI 1.08-1.58), peripheral vascular disease (aHR 1.28, 95% CI 1.05-1.55), cardiovascular events (aHR 1.33, 95% CI 1.01-1.73), and venous thromboembolic events (aHR 2.15, 95% CI 1.48-3.13). Adjusted mortality was similar between the 2 groups. Conclusion Adrenal adenomas are associated with an increased prevalence and incidence of adverse cardiometabolic outcomes in a population-based cohort.

Autonomous cortisol secretion (ACS) affects up to 50% of patients with adrenal adenomas. Despite the limited evidence, clinical guidelines recommend measurement of serum concentrations of dehydroepiandrosterone-sulfate (DHEA-S) and corticotropin (ACTH) to aid in the diagnosis of ACS. Our objective was to determine the accuracy of serum concentrations of DHEA-S and ACTH in diagnosing ACS. We conducted a retrospective single center study of adults with adrenal adenoma evaluated between 2000−2020. Main outcome measure was diagnostic accuracy of DHEA-S and ACTH. ACS was defined as post-dexamethasone cortisol >1.8 mcg/dL. Of 468 patients, ACS was diagnosed in 256 (55%) patients with a median post-DST cortisol of 3.45 mcg/dL (range, 1.9–32.7). Patients with ACS demonstrated lower serum concentrations of DHEA-S (35 vs. 87.3 mcg/dL, p < 0.0001) and ACTH (8.3 vs. 16 pg/mL, p < 0.0001) compared to patients with non-functioning adrenal tumors (NFAT). Serum DHEA-S concentration <40 mcg/dL diagnosed ACS with 84% specificity and 81% PPV, while serum ACTH concentration <10 pg/mL diagnosed ACS with 75% specificity and 78% PPV. The combination of serum concentrations of DHEA-S <40 mcg/dL and ACTH <10 pg/mL diagnosed ACS with the highest accuracy with 92% specificity and 87% PPV. Serum concentrations of DHEA-S and ACTH provide additional value in diagnosing ACS.

AbstractContextThe COVID-19 pandemic has impacted healthcare environment.ObjectiveTo determine the impact of the pandemic on self-reported outcomes in patients with adrenal insufficiency (AI).Design and settingProspective longitudinal survey study at 2 tertiary centers.ParticipantsPatients with AI.InterventionPatient-centered questionnaire.Main outcome measuresDepression Anxiety Stress Scales-21, Short Form-36, and AI self-management.ResultsOf 342 patients, 157 (46%) had primary AI, 109 (32%) had secondary AI, and 76 (22%) had glucocorticoid-induced AI. When compared to prepandemic, daily glucocorticoid dose and number of adrenal crises did not change. However, patients reported a higher financial impact from AI (34% vs 23%, P = 0.006) and difficulty accessing medical care (31% vs 7%, P &lt; 0.0001) during the pandemic. A third of patients reported difficulty managing AI during the pandemic. After adjusting for duration and subtypes of AI, younger patients [odds ratio (OR) 2.3, CI 95% 1.3-4.1], women (OR 3.7, CI 95% 1.9-7.1), poor healthcare access(OR 4.2, CI 95% 2.3-7.7), lack of good insurance support (OR 2.8, CI 95% 1.3-5.9), and those with a higher financial impact (OR 2.3, CI 95% 1.3-4.3) reported greater difficulties managing AI. Patients were more likely to report a higher anxiety score (≥8) if they found managing AI challenging during the pandemic (OR 3.0, CI 95% 1.3-6.9), and had lower Physical Component Summary (OR 4.9, CI 95% 2.2-11.0) and Mental Component Summary (OR 4.1, CI 95% 1.8-9.5) scores prior to the pandemic.ConclusionsA third of patients with AI reported difficulties with management of AI during the pandemic, particularly in younger patients, women, and those with poor healthcare access.

Abstract Introduction: Optimal initial antithyroid drugs (ATD) dosing may achieve rapid improvement in thyroid hormone levels while minimizing risk of adverse events. As ATD have become the most common first line therapy for the treatment of Graves’ disease (GD), we examined trends over time in initial ATD dosing, and the association between guideline-based ATD dosing with time to normalization of FT4 and frequency of adverse events. Methods: This is a single cohort retrospective study in Mayo Clinic, Rochester, MN. We identified adults (≥18 years old) diagnosed with new onset GD between January 1, 2002-December 31, 2019 treated with at least 14 days of ATD and with available initial follow up data within 3 months prior to a dose change. Propylthiouracil (PTU) doses were converted to Methimazole (MMI) equivalents at 10:1 ratio. Guideline concordant care was defined as initial ATD dosed based on 2016 American Thyroid Association guidelines (i.e. 5-10 mg for presenting FT4 between &gt;1.7-2.55 ng/dL, 10-20 mg for 2.56-3.40 ng/dL, and 30-40 mg for 3.41 ng/dL and above). Based on the first follow up FT4 values, patients were grouped into categories of: normal range (FT4 0.9-1.7 ng/dL) and under treated (FT4 &gt;1.7 ng/dL). Results: 398 patients were included; mean (SD) age was 49 years (16.6), and 75% were women. Mean initial (SD) Free T4 value was 3.9 ng/dL (2.8), with patients treated with ATD at mean (SD) starting dose of 21.9 mg (13.3) MMI equivalent. Over time there was a decrease in the starting ATD dose from 30 mg MMI equivalent in 2002-2004 to 20 mg in 2017-2019, despite steady presenting FT4 values (2.7 ng/dL in 2002-2005 and 3.1 ng/dL in 2017-2019). In the subset of 340 patients with overt hyperthyroidism, 181 (53%) received guideline concordant (GC) dosing. Patients receiving GC care had a higher initial FT4 (4.9 vs. 3.6 ng/dL, p=0.002), larger goiters (40 vs. 30 g, p&lt;0.001) and higher initial ATD mean dose (SD) 25 mg (15.7) vs. 21.3 mg (9.9), p= 0.05. However at follow up (median 32 days vs 35 days respectively), both groups had similar proportion of patients with normal FT4 values (43% vs. 42%, p=0.79); undertreated patients (45% vs. 45%, p=0.99) and frequency of adverse events (4% vs. 6%, p=0.40). Conclusion: The initial dose of ATD for the treatment of GD has decreased over the past 2 decades. Most clinicians initiate ATD at a dose concordant to guidelines. Despite this, a significant proportion of patients have persistent hyperthyroidism on initial follow up. In light of evidence of risks associated with duration of hyperthyroidism, strategies to improve optimization of initial dosing are needed. Pending further subgroup analysis by presenting FT4 severity, these preliminary results suggest and approach factoring other variables apart from guideline based initial ATD dose is needed to optimize response. Our data will be utilized to pilot an individualized, patient specific predictive model to guide initial dosing to this end.
