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.
LBSAT141 Bone Health In Patients With Adrenal Disorders
Abstract Introduction Limited data suggest low bone density in patients with adrenal adenomas. However, most studies are retrospective, single-center, and none were conducted in the United States. We aimed to determine the impact of cortisol and aldosterone excess on bone density. Methods We conducted a preliminary analysis of data from our multicenter, prospective observational study of adult patients with adrenocortical hormone excess and referent subjects without adrenal disorders (January 2019 - March 2022). Patients were diagnosed with non-functioning adenomas (NFA), adenomas with mild autonomous cortisol secretion, MACS (defined as cortisol following an overnight 1-mg dexamethasone suppression test (DST)>1.8 mcg/dL), adrenal or pituitary Cushing syndrome (CS), primary aldosteronism (PA), and concomitant PA-MACS. Referent subjects were patients undergoing cross-sectional imaging for reasons other than adrenal disease. All participants were interviewed about their bone health, and had bone density measurements at the spine, hips, and/or radius. Bone disease was defined as osteopenia (T-score -1.1 to -2.4), or osteoporosis (T-score < -2.5). Results A total of 417 participants included 156 referent subjects (88, 56% women, median age 65, range 2-95 years) and 261 patients (190, 73% women, median age 59, range 21-88 years). Patients were diagnosed with NFA (51, 19%), PA (46, 17%), MACS (122, 47%), PA-MACS (12, 5%), and CS (30,12%). When compared to referent subjects, sex- and age-adjusted analysis demonstrated an increased prevalence of bone disease only in patients with CS (OR 4.8, 95%CI 1.7-13), but not in other adrenal disorders. After excluding patients with CS, those with post-DST cortisol >5 mcg/dL demonstrated a higher prevalence of bone disease when compared to patients with post-DST cortisol between 1.8-5 mcg/dL (OR 2.8, 95%CI 1.2-6.5) and those with post-DST cortisol <1.8 mcg/dL (OR 2.7, 95% CI 1.1-6.7). Patients with MACS and post-DST cortisol between 1.8-5 mcg/dL did not demonstrate increased sex and age-adjusted prevalence of bone disease compared to those with post-DST <1.8 mcg/dL or referent subjects. However, using post-DST cortisol as a continuous variable, we found that after adjusting for sex and age, the risk of bone disease in patients increased by 13% (OR 1.13, 95%CI 1.6-1.2) for every 1 mcg/dL increase in post-DST cortisol. Conclusions The prevalence of osteopenia and osteoporosis increases proportional to the increase in post-DST cortisol concentrations. Patients with CS, and those with MACS and post-DST cortisol > 5mcg/dL have the highest prevalence of bone disease. Presentation: Saturday, June 11, 2022 1:00 p.m. - 3:00 p.m.
The metabolic phenotype of patients with primary aldosteronism: impact of subtype and sex – a multicenter-study of 3566 Caucasian and Asian subjects
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.
Cardiometabolic Disease Burden and Steroid Excretion in Benign Adrenal Tumors
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.
Diagnostic Accuracy of Dehydroepiandrosterone Sulfate and Corticotropin in Autonomous Cortisol Secretion
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.
Incident Cardiometabolic Outcomes in Adrenal Adenomas: A Population-Based Cohort Study of 1,004 Patients
Abstract Background: Adrenal adenomas have been linked with cardiovascular morbidity in selected patient populations from specialized referral centers. Population-based data examining the association of adrenal adenomas with cardiometabolic outcomes are lacking. Aim: To determine the incidence of cardiometabolic outcomes in a population-based cohort of patients with adrenal adenomas. Methods: We conducted a population-based cohort study of patients diagnosed with adrenal adenomas while living in a defined community from 1995–2017. Eligible patients were retrospectively identified by a medical records linkage system and confirmed on chart review. Adenomas were classified as mild autonomous cortisol secretion (MACS) if the serum cortisol concentration was >1.8 mcg/dL after 1 mg overnight dexamethasone suppression test (DST), nonfunctioning adrenal tumor (NFAT) if serum cortisol after DST was ≤1.8 mcg/dL, and adenoma with unknown cortisol secretion (AUCS) if DST was not performed. Patients with overt hormone excess were excluded. Cardiometabolic outcomes were assessed at the time of adrenal adenoma diagnosis. Patients were then followed until death, migration out of the community, or through December 31, 2017. Incident outcomes were assessed starting at 1 year following the diagnosis and excluded those with the outcome of interest at baseline, except for myocardial infarction (MI) and coronary intervention, which were adjusted for in the analysis. Results: were compared to 1:1 age and sex-matched referent subjects without adrenal adenomas from the same community. Results: Adrenal adenomas were diagnosed in 1004 patients with 141 (14%) NFAT, 81 (8%) MACS, and 782 (78%) AUCS. The median age of diagnosis was 63 years (range, 20–96), and 582 (58%) were women. The baseline data was previously presented and showed higher prevalence of hypertension, diabetes, peripheral vascular disease (PVD), and heart failure (HF) in the adenoma group, after adjusting for BMI and tobacco use. During a median follow-up of 6.8 years (range, 0–22), patients with adrenal adenomas were more likely than referent subjects to develop new-onset dyslipidemia (HR 1.31, 95% CI 1.03–1.67), diabetes (HR 1.68, 95% CI 1.28–2.22), chronic kidney disease (HR 1.77, 95% CI 1.39–2.25), atrial fibrillation (HR 1.32 (1.03–1.70), PVD (HR 1.61, 95% CI 1.24–2.09), and HF (HR 1.46, 95% CI 1.15–1.85). In addition, the adenoma group had higher risk for incident MI (HR 1.62, 95% CI 1.16–2.25) and coronary intervention (HR 1.70, 95% CI 1.25–2.31). Conclusions: Adrenal adenomas are associated with increased incidence of adverse cardiometabolic outcomes in this population-based cohort study. While these results are potentially explained by different degrees of cortisol excess, the majority of patients received suboptimal hormone evaluation, suggesting a knowledge gap in the workup of adrenal adenomas in the broader medical community.
Impaired Muscle Strength and Performance in Patients With Mild Autonomous Cortisol Secretion
Abstract Background: Glucocorticoid-induced myopathy is well-recognized in overt Cushing syndrome (CS), but the impact of mild cortisol secretion on muscle is unclear. Recent data suggest that patients with mild autonomous cortisol secretion (MACS) are frailer and report more weakness than patients with non-functioning adrenal adenomas. We hypothesized that MACS is associated with 1) objective measures of impaired muscle strength and performance and 2) increased tissue accumulation of advanced glycation end products (AGEs), a measure of accelerated aging. Aim: To determine the effect of MACS on muscle mass, strength, performance, and tissue accumulation of AGEs. Methods: We conducted a cross-sectional analysis as part of an ongoing cohort study in patients with MACS compared to age and sex-matched referent subjects without cortisol excess. MACS was defined as serum cortisol >1.8 mcg/dL after the 1 mg overnight dexamethasone suppression test (DST), in the absence of overt signs and symptoms of CS. We measured hand grip strength with hand grip dynamometer and evaluated functional performance on the timed up and go test, 6 minute walk test, and gait speed assessment. Tissue accumulation of AGEs was measured with point-of-care AGE reader. Appendicular lean mass was calculated and adjusted for height in participants who underwent body composition scan. Results: A total of 23 patients with MACS and 23 age and sex-matched referent subjects without cortisol excess were enrolled. The median age of diagnosis was 63 years (range, 51–81), and 26 (56%) were women. In the MACS cohort, median cortisol following 1 mg DST was 2.6 µg/dL (range, 1.9–13.0), median DHEA-S 37 µg/dL (range, 5.0- 141.0), and median ACTH 8.5 pg/mL (range, 5.0–38.0). Patients with MACS had lower hand grip strength (median 29.3 vs. 32.5 kg, p=0.052), slower gait speed (median 1.1 vs. 1.4 m/s, p=0.001), covered less distance during the 6 minute walk test (median 453 vs. 510 m, p=0.001), and took longer to complete the timed up and go test (median 10.1 vs. 8.6 s, p=0.04) than referent subjects without cortisol excess. Accumulation of AGEs was higher in patients with MACS (median 2.9 vs. 2.4, p=0.01). No significant difference was observed in appendicular lean mass (n=19 pairs, 7.8 vs. 7.5 kg/m2, p=0.57). Conclusions: MACS is associated with decreased muscle strength and performance without a significant change in muscle mass, suggesting poor muscle quality. We also observed increased tissue accumulation of AGEs in MACS patients, consistent with our hypothesis of MACS-induced accelerated aging. These findings may help explain the increased frailty observed in MACS, and suggest muscle assessment be considered in all patients with autonomous cortisol secretion. Further studies should examine the impact of muscle and functional impairments on morbidity in MACS, and its possible reversal with either a structured exercise intervention or adrenalectomy.
Risk of Mental and Sleep Disorders After the Diagnosis of Adrenal Adenomas: A Population-Based Cohort Study
Abstract Background: Adrenal adenomas are incidentally diagnosed in 7% of adults undergoing abdominal imaging. Mild autonomous cortisol secretion is present in 50% of adrenal adenomas, and even “nonfunctioning” adrenal adenomas demonstrate abnormal steroid profile. We aimed to 1) investigate the prevalence of mental and sleep disorders in patients with adrenal adenomas and to 2) determine the risk of mental and sleep disorders after the diagnosis of adrenal adenoma in patients compared to the referent subjects from the same population Methods: Using a medical records linkage system, we identified adult patients living in the Olmsted County, MN diagnosed with an adrenal adenoma during 1995–2017. Patients with overt hormone excess were excluded. Every patient with adenoma was matched by sex and age to a referent subject from the same population. Subjects were followed until death or end of the study. Mental health related comorbidities and sleep disorders were assessed at baseline and during follow up. Results: Our cohort included 1004 patients with adrenal adenomas and 1004 referent subjects (58% women, median age of 63 years). Patients were more likely to smoke (70% vs 54%, p <0.001) and had a higher BMI (30 kg/m2 vs 28 kg/m2, p < 0.001). Within 5 years prior to the index date (diagnosis of adenoma), and after adjusting for BMI and smoking, patients demonstrated a higher prevalence of depression (Odds ratio, OR of 1.3 (CI95% 1.1–1.6), p=0.02), anxiety (OR of 1.4 (CI95% 1.1–1.8, p=0.003), substance abuse disorders (OR of 2.4 (CI 95% 1.7–3.4), p<0.001), but not insomnia (OR of 1.2 (CI95% 0.9–1.7) and sleep related breathing disorders (OR of 1.3 (CI 95% 0.9–1.7). During follow-up, starting 1 year after the diagnosis, patients demonstrated a higher risk of new onset depression (HR of 1.9, CI95%1.5–2.4), anxiety (HR of 1.5,CI95% 1.2–1.9), schizophrenia (HR of 1.7, CI95% 1.2–2.4), and substance abuse disorders (HR of 1.6, CI95% 1.2–2.0). Risk of sleep disorders 1 year after diagnosis was also high for insomnia (HR of 1.4, CI95% 1.1–1.9), sleep-related breathing disorders (HR of 1.8, CI95% 1.4–2.3), hypersomnias of central origin (HR of 2.0, CI95%1.04–3.96), parasomnias (HR of 2.4, CI95%1.2–4.7), and sleep-related movement disorders(HR of 1.9, CI95%1.3–2.6). Conclusion: Patients with adenomas are at increased risk for mental and sleep disorders, possibly explained by the underlying subtle cortisol secretion. Further prospective studies with an in-depth characterization of both hormonal secretion and mental/sleep disorders are needed. Reversibility or improvement of mental health and sleep disorders with adrenalectomy should be investigated.
Impaired Cognitive Performance in Patients With Mild Autonomous Cortisol Secretion
Abstract Background: Cognitive deficits in memory, language, and executive function have been described in Cushing’s syndrome, but the impact of mild cortisol secretion on cognition is unclear. Rather than overt hypercortisolism, mild autonomous cortisol secretion (MACS) is typically associated with abnormal circadian cortisol production. Aim: To characterize the effect of MACS on cognitive performance. Methods: We conducted a cross-sectional analysis as part of an ongoing cohort study in patients with MACS compared to age and sex-matched referent subjects without cortisol excess. MACS was defined as serum cortisol concentration >1.8 mcg/dL after the 1 mg overnight dexamethasone suppression test (DST), in the absence of signs and symptoms of overt Cushing syndrome. We used the National Institute of Health Toolbox Cognition Battery to assess cognitive performance. A series of seven IPad-based tests were administered to evaluate five key domains: 1) executive function, 2) episodic memory, 3) working memory, 4) language, and 5) processing speed. Performance was reported using fully corrected T-scores for age, sex, education, and race with a normative mean of 50 and a standard deviation of 10. T-scores were generated for the individual components as well as three summary measures: 1) fluid cognition (includes executive function, episodic memory, working memory, and processing speed), 2) crystallized cognition (includes language), and 3) total cognition (composite of fluid and crystalized cognition). Results: A total of 23 patients with MACS and 23 age and sex-matched referent subjects without cortisol excess were enrolled. The median age of diagnosis was 63 years (range, 51–81), and 26 (56%) were women. In the MACS cohort, median cortisol following 1 mg DST was 2.6 ug/dL (range, 1.9–13.0) with median ACTH of 8.5 pg/mL (range, 5.0–38.0) and median DHEA-S of 37 mcg/dL (range, 5.0- 141.0). On cognitive assessment, patients with MACS had lower total cognition (T-scores 50 vs. 54, p=0.05) and fluid cognition (T-scores 48 vs. 53, p=0.01) composite scores compared to referent subjects without cortisol excess. In particular, patients with MACS performed worse on tests of executive function (Dimensional Change Card Sort: T-scores 55 vs. 63, p= 0.02 and Flanker Inhibitory Control and Attention: T-scores 45 vs. 52, p=0.01). There were no significant differences observed in the remaining individual domains of language, processing speed, working memory, and episodic memory, or crystallized cognition. Conclusions: MACS is associated with impaired total cognition, and in particular, executive function and fluid cognition. These findings suggest that patients with MACS are susceptible to cortisol-mediated changes in the brain. Additional studies should examine the contribution of neuropsychiatric symptoms on cognition in MACS, and possible improvement following treatment for cortisol excess.
