Meditation may be an effective intervention to alleviate the severity of GWS. Objective: To determine the acceptability of portable, wearable EEG device for guided meditation (MUSE headband) and the impact of MUSE use on GWS and quality of life 12 weeks post-surgery. Methods: We conducted a single-center prospective cohort study of adults with endogenous hypercortisolism undergoing curative surgery, 2019-2024. Patients had baseline and post-surgical assessments over 12 weeks. The study comprised of patients using MUSE for ≥ 6 weeks (MUSE cohort) and patients matched by age, sex, BMI, hypercortisolism type, and glucocorticoid type at 1:4 ratio. Quality of life and symptoms of GWS were assessed with AddiQoL, Cushing Quality of Life, and Short Form-36 mental and physical component (SF-36 MCS and PCS) questionnaires. Results: MUSE was offered to 52 patients, and 22 (42%) used MUSE for ≥ 6 weeks within 12 weeks post-surgery. At baseline, when compared to 88 matched subjects, 22 MUSE participants demonstrated a similar prevalence of comorbidities, clinical and biochemical hypercortisolism severity, but lower AddiQoL (mean 73 vs 66, P=0.031) and SF-36 MCS (mean 39 vs 33, P=0.022). At 12 weeks, these differences in quality of life were no longer present. After adjusting for age, sex, BMI, clinical severity score, and baseline quality of life, MUSE use was an independent predictor of improved SF- 36 PCS at 12 weeks post-surgery (beta 4.2, 95% CI: 0.5-7.9, P=0.026). Conclusions: Meditation intervention post-surgery may improve symptoms of GWS and accelerate recovery. Presentation: Sunday, July 13, 2025

Patients with Mild Autonomous Cortisol Secretion (MACS) demonstrate a high prevalence of frailty, however, no data are available on the impact of management on frailty progression. Objectives: To determine the impact of conservative vs surgical management on and the progression of frailty in patients with MACS. Methods: We conducted a multicenter prospective cohort study of patients with (MACS), primary aldosteronism (PA), or non-functioning adrenal adenomas (NFA) between June 2020 and April 2025. Participants completed standardized frailty assessment (frailty index) at baseline and annually. Results: A total of 691 patients were included: 253 with MACS (median age 62 years, 73% women, 230 with NFA (median age 62 years, 67% women), and 208 with PA (median age 54 years, 50% women). At baseline, prevalence of frailty was highest patients with MACS (39%), followed by patients with PA (31%) and NFA (24%). Frailty was reassessed at 1 year post baseline in 189 patients with NFA (22% frail, median frailty index of 0.17) and 116 patients with MACS (27% frail, median frailty index of 0.16) managed conservatively, as well as in 108 patients with MACS treated with adrenalectomy (49% frail, median frailty score of 0.24). Conservatively treated patients with MACS and those treated with adrenalectomy had similar post-dexamethasone cortisol (median 2.9 mcg/dL vs 3.1 mcg/dL, p=0.396), but were older (median age 65 years vs 58 years, p=0.001) At one year follow up, patients with MACS treated with adrenalectomy demonstrated an improvement in frailty when compared to conservative management (delta frailty index: Est of −0.044, p = 0.004), after adjusting for age and sex. In contrast, when compared to conservatively managed patients with NFA, conservatively managed patients with MACS demonstrated worse frailty at 1 year follow up (delta frailty index: Est of 0.028, p = 0.013). Conclusion: In comparison to patients with NFA, conservatively managed patients with MACS demonstrated worse frailty at 1 year follow up. In contrast, adrenalectomy in patients with MACS led to improvement of frailty. Frailty index could be valuable to identify patients most likely to benefit from adrenalectomy. Patients with higher baseline frailty scores were more likely to undergo adrenalectomy, Presentation: Sunday, July 13, 2025

ABSTRACT Objective Data on bone health in patients with mild autonomous cortisol secretion (MACS) are limited and heterogenous. We sought to assess the prevalence of osteoporosis and symptomatic fragility fractures in patients with adrenal adenomas and hypercortisolism, and explore associations with the degree of cortisol excess and frailty. Design This multicenter cross ‐sectional study involved prospective enrollment of adults with nonfunctioning adrenal adenomas (NFA), MACS, Cushing syndrome (CS) and referent subjects without adrenal disorders during the study period (January 2019–September 2022). All participants completed a bone health questionnaire at enrollment and had dual‐energy X ‐ray absorptiometry bone mineral density assessment within 12‐months. Final analyses were adjusted for age, sex, body mass index, smoking status, alcohol use. Results Participants included 117 with NFA (median age 62 years, 80% women), 191 with MACS (median age 63 years, 74% women), 62 with CS (median age 50 years, 92% women), and 101 referent subjects (median age 59 years, 47% women). Both patients with CS (OR: 3.0, 95% CI: 1.1–8.3) and MACS (OR: 2.2, 95% CI: 1.9–4.9) had a higher prevalence of osteoporosis when compared to referents. Among patients with MACS, only those with post 1‐mg dexamethasone suppression test (post‐1mg‐DST) cortisol > 83 nmol/L had a higher prevalence of osteoporosis when compared to referents (OR: 3.2, 95% CI: 1.4–7.5) and NFA (OR: 2.2, 95% CI: 1.1–4.4). For clinical fragility fractures, only patients with CS showed an increased prevalence when compared to referents (OR: 6.1, 95% CI: 1.7–26.4) and NFA (OR: 3.8, 95% CI: 1.3–11.2). Prevalence of clinical fragility fractures was similar to referents in patients with MACS (OR: 1.8, 95% CI: 0.6–6.9) and NFA (OR: 1.5, 95% CI: 0.4–6.1), and was not associated with post‐1mg‐DST cortisol or frailty in the MACS and NFA groups. Conclusion Patients with CS, and those with MACS and post‐1mg‐DST cortisol > 83 nmol/L, exhibited a higher burden of osteoporosis. However, only CS was associated with an elevated risk of symptomatic fragility fractures.

Abstract Context Patients with mild autonomous cortisol secretion (MACS) can develop adrenal insufficiency after unilateral adrenalectomy. Objective This work aimed to determine the prevalence, duration, and predictors of adrenal insufficiency, and compare postoperative basal cortisol and cosyntropin stimulation test (CST). Methods In this multicenter retrospective study of patients with MACS, adrenal insufficiency was diagnosed when postoperative basal cortisol was less than 10 µg/dL and/or CST < 18 µg/dL. The results were concordant when both tests met cutoffs. Biochemical (BSS) and clinical severity scores (CSS) were calculated. Results Among 281 patients with MACS (80% women), postoperative adrenal insufficiency was diagnosed in 153 (54.5%) patients. Adrenal insufficiency inversely correlated with age (odds ratio [OR] 0.67 per 10 years; 95% CI, 0.53-0.84). Low basal cortisol and CST were associated with younger age (OR 0.64 per 10 years for both) and higher BSS (OR 1.17 and 1.22, respectively). Basal cortisol and CST were discordant in 22% of patients, and the discordance rate was more common in patients with bilateral nodules (32% vs 19%; P < .001). The median time to adrenal insufficiency recovery was 3.9 months (IQR, 3-5.9 months), with longer duration associated with higher BSS and CSS: 3 months for mild, 4 to 5 months for moderate, and 12 to 14 months for severe BSS and CSS. Conclusion Approximately half of patients with MACS developed postoperative adrenal insufficiency, with 50% recovering by 3.9 months after surgery. BSS correlated with basal cortisol, CST, and duration of adrenal insufficiency. As discordant results were noted in 22%, performing both basal cortisol and CST postoperatively should be considered.

Abstract Context Patients with endogenous hypercortisolism experience glucocorticoid withdrawal syndrome (GWS) after surgery. Meditation may be an effective intervention to alleviate the severity of GWS. Objective To determine the acceptability of a portable, wearable electroencephalography device for guided meditation (MUSE headband) and the impact of MUSE use on GWS and quality of life 12 weeks postsurgery. Methods We conducted a single-center prospective cohort study of adults with endogenous hypercortisolism undergoing curative surgery from 2019 to 2024. Patients had baseline and postsurgical assessments over 12 weeks. The study comprised patients using MUSE for ≥ 6 weeks (MUSE cohort) and patients matched by age, sex, BMI, hypercortisolism type, and glucocorticoid type at 1:4 ratio. Quality of life and GWS symptoms were assessed with AddiQoL, CushingQoL, and 36-item Short Form Health Survey mental and physical component (SF-36 MCS and PCS) questionnaires. Results MUSE was offered to 52 patients, and 22 (42%) used MUSE for ≥ 6 weeks within 12 weeks after surgery. At baseline, compared to 88 matched subjects, 22 MUSE participants demonstrated similar prevalence of comorbidities and clinical and biochemical hypercortisolism severity, but lower AddiQoL (mean 73 vs 66, P = .031) and SF-36 MCS (mean 39 vs 33, P = .022). At 12 weeks, these differences in quality of life were no longer present. After adjusting for age, sex, BMI, clinical severity score, and baseline quality of life, MUSE use was an independent predictor of improved SF-36 PCS at 12 weeks postsurgery (beta 4.2, 95% CI: 0.5-7.9, P = .026). Conclusion Postsurgical meditation intervention may improve physical symptoms and accelerate recovery.

Abstract Context Data on diagnostic accuracy of dehydroepiandrosterone sulfate (DHEA-S) for mild autonomous cortisol secretion (MACS) and adrenal insufficiency (AI) are discrepant. Objective We conducted a systematic review and meta-analysis of published studies assessing the accuracy of DHEA-S in diagnosing MACS or AI. Methods From inception to January 8, 2024, we searched databases for original studies of at least 20 participants with MACS or AI. MACS was defined as postdexamethasone cortisol greater than 1.8 mcg/dL or postsurgical hypocortisolism. AI was defined by abnormal dynamic testing. QUADAS-2 was used to assess the risk of bias. Bivariate random effects meta-analysis was used to generate pooled diagnostic accuracy estimates. Results Seven studies on DHEA-S accuracy in diagnosing MACS (574 patients with MACS, 830 referent individuals), and 2 studies on DHEA-S accuracy in diagnosing AI (52 patients with AI, 59 referent individuals) were included. A meta-analysis of studies using DHEA-S cutoff between 60 and 70 mcg/dL to diagnose MACS demonstrated a sensitivity of 82% (95% CI, 64%-93%) and a specificity of 82% (95% CI, 74%-88%). In the 2 studies evaluating DHEA-S in diagnosing AI, the reference standard was a 1-mcg cosyntropin stimulation test. The sensitivity of DHEA-S for diagnosing AI ranged from 70.3% to 86.7%, and the specificity was 87.1%. Most studies were at a moderate risk of bias. Conclusion Based on limited heterogeneous evidence, measurement of DHEA-S provides additional value in diagnosing MACS, as well as AI.

Introduction: Patients with mild autonomous cortisol secretion (MACS) are at risk for adrenal insufficiency (AI) after unilateral adrenalectomy. We aimed to determine the prevalence, predictors, and duration of AI after unilateral adrenalectomy for MACS, and to compare baseline and peak cortisol post cosyntropin stimulation test (CST) in diagnosing AI. Methods: We conducted a dual-center retrospective cohort study of patients with MACS who underwent unilateral adrenalectomy and were evaluated with postoperative cosyntropin stimulation test (CST). AI was diagnosed when postoperative morning cortisol was <10μg/dL and/or CST peak cortisol was <18μg/dL. Baseline and CST peak cortisol levels were considered concordant when both met corresponding cut-offs. Biochemical (BSS) and clinical (CSS) severity scores for hypercortisolism were calculated. Results: In 100 adults with MACS (77% women, median age 56 years, interquartile range [IQR] 48-63), median adenoma size was 2.8 cm (IQR, 2.2-3.7), and 25 (25%) had bilateral nodules. Median BSS was 3 (IQR, 2-5) and median CSS was 4 (IQR, 2-8). After adrenalectomy, AI was diagnosed in 56 (56%) patients. AI was associated with higher BSS, larger tumor size, but not age, sex, BMI, tumor laterality. Baseline and CST peak cortisol levels were concordant in 76% of cases. In 14% of cases morning cortisol was <10μg/dL but CST peak cortisol was ≥18μg/dL, and in 10% of cases morning cortisol was ≥10μg/dL, but CST peak cortisol was <18μg/dL. On a multivariable analysis that included age, sex, BMI, BSS, laterality, and tumor size, only higher BSS (odd ratio [OR] = 1.6 per 1 point) was associated with postoperative baseline cortisol <10μg/dL (P<0.05 for all). Independent predictors of CST peak cortisol <18μg/dL were BSS (OR 1.5 per 1 point) and unilateral adenoma (OR 3.7). During a median postoperative follow up of 13 months, 33 (59%) patients recovered from AI. Median time to recovery was 6.0 months, with AI recovery in 28% of patients by 2 months, 42% by 3 months, 53% by 6 months, and 64% by 12 months. Conclusions: Prevalence of postoperative AI in MACS was 56%. Only 76% of patients had concordant baseline and CST peak cortisol, with peak CST cortisol being more commonly abnormal in patients treated for unilateral MACS. Patients with larger adenomas and higher BSS were at higher risk for AI. Patients with MACS should be counseled about the risk and duration of AI after adrenalectomy. Presentation: 6/3/2024

Abstract Disclosure: B. Salama: None. J. Saini: None. V. Fell: None. E.J. Atkinson: None. S.J. Achenbach: None. Background: Mildly autonomous cortisol secretion (MACS) can be unilateral in 80% of cases, or bilateral in 20% of cases, due to either bilateral adrenal adenomas or bilateral macronodular adrenal hyperplasia. Scarce evidence demonstrates the differences in plasma steroid profiling of patients with bilateral versus unilateral MACS, however, these findings have not been confirmed using a more comprehensive 24h urine steroid profiling. Objectives: To characterize 24h urine steroid metabolome in patients with unilateral and bilateral MACS. Methods: We conducted a single-center cross-sectional study between 2019-2022. Eligible participants included consecutive patients with MACS who provided a 24h urine sample. Urine was analyzed for 25 steroids with a high-resolution mass spectrometry assay. MACS was defined as cortisol >1.8 mcg/dL following the overnight administration of 1 mg dexamethasone (DST-cortisol). Partial cohort analysis is presented. Results: Of 72 patients with MACS included in the interim analysis, 36 (50%) had bilateral MACS. The two groups (unilateral vs bilateral) were similar in age (median 58 vs 58 years), sex (women 67% vs 61%), BMI (median 33 vs 32 kg/m2), and menopausal status (36% vs 39%), P>0.05 for all. Prevalence of comorbidities was also similar in both groups: hypertension (89% vs 89%), hyperlipidemia (69% vs 78%), and hyperglycemia (69% vs 61%), P >0.05 for all. While the DST-cortisol (median 3.0 vs 3.2 mcg/dL, P= 0.51) and dehydroepiandrosterone sulfate (DHEAS) (median 37.5 vs 55.0, P = 0.21) were similar between the 2 groups, patients with bilateral MACS had a lower ACTH (median 12.4 vs 8.2 pg/mL, P = 0.012) when compared to patients with unilateral MACS. Median adrenal mass size was similar in patients with both unilateral MACS (2.7 cm, IQR 1.7-3.9) and bilateral MACS (3.0 cm, IQR 2.2-3.6) P = 0.54. Of the 25 steroids measured, only tetrahydrocorticosterone was higher in patients with unilateral MACS (median 245 mcg/24h, IQR 165-416 vs median 184 mcg/24h, IQR 121 -278) P = 0.039. No differences in androgens (median 2229 vs 2036 mcg/24h), cortisol metabolites (median 6566 vs 5191 mcg/24h), cortisone metabolites (median 10300 vs 9429 mcg/24h), or glucocorticoid/androgen ratio (median 7.9 vs 8.9) was demonstrated between the unilateral vs bilateral MACS groups (P>0.05 for all). Conclusion: In this interim analysis of patients with unilateral vs bilateral MACS, we have found that patients had a similar post-DST cortisol and similar tumor bulk. Despite a lower ACTH in patients with bilateral MACS, no differences in androgens were found between the two groups. In addition to expanding steroid profiling analysis to the whole cohort, subgroup analyses will need to distinguish between patients with bilateral adenomas and macronodular adrenal hyperplasia, consider aldosterone co-secretion, and employ a more accurate measurement of adrenal tumor bulk.

Abstract Disclosure: J. Saini: None. B. Salama: None. S.R. Chacko: None. K. Yu: None. I. Bancos: None. Objective: Measurement of baseline dehydroepiandrosterone sulfate (DHEAS) is suggested by the guidelines in support of diagnosing mild autonomous cortisol secretion (MACS). However, evidence on the diagnostic accuracy of DHEAS in MACS is difficult to interpret due to differences in the diagnostic cutoffs, small sample size, and heterogeneous reference standards. We aimed to conduct a systematic review and meta-analysis of published literature to assess the performance of DHEAS in diagnosing MACS, as defined in the 2023 guidelines. Methods: A comprehensive search was conducted using several databases from each database’s inception to January 8th, 2024. Databases include Ovid MEDLINE (R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Databases of Systematic Reviews, and Scopus. Only original studies of at least 20 participants were included. MACS was defined as post-dexamethasone cortisol >1.8 mcg/dL. QUADAS-2 was used to assess the risk of bias. Bivariate and random effects meta-analysis was used to generate pooled diagnostic accuracy estimates. Results: The initial search yielded 285 articles, and only 7 studies met the inclusion criteria. In 7 studies (1 from North America, 3 from Asia, and 3 from Europe), a total of 574 patients with MACS and 830 referent subjects (patients with adrenal tumors without MACS) were included. The mean age was specified only in 5 studies and was similar in patients with MACS (55.5 years) and referent group (53.3 years). Patients with MACS had a higher number of women (323/472, 68.4%) as compared to the referent group (352/658, 53.4%). DHEAS cutoffs studied included: lower cutoff of age-and sex-specific ranges (3 studies), 40 mcg/dL (3 studies), 60 mcg/dL (1 study), and 67.5 mcg/dL (1 study). With increasing DHEAS cutoff, sensitivity for MACS diagnosis increased, and specificity decreased. Most studies (4 studies) used the chemiluminescent immunoassay to measure DHEAS. A meta-analysis of studies using DHEAS cut-off between 40-70 mcg/dL was performed, with a pooled sensitivity of 68% (95% CI: 51-81) and a pooled specificity of 85% (78-89). The positive likelihood ratio was 4 (95% CI: 3-6; I2=36.94, P=0.175) and the negative likelihood ratio was 0.4 (0.3-0.6; I2=49.97, P=0.092). Most studies were at a high risk of bias for selection of patients, index, or reference standard. Conclusion: Based on limited heterogeneous evidence, measurement of DHEAS provides additional value in diagnosing MACS. Further larger diagnostic accuracy studies should explore various DHEAS cutoffs and consider assay variability. Presentation: 6/3/2024
