Abstract Objective Evidence on the duration of post-operative adrenal insufficiency (AI) in patients with endogenous hypercortisolism is scarce. We sought to determine the duration of post-operative AI and to identify factors associated with the duration of AI in patients undergoing surgery for endogenous hypercortisolism. Methods We conducted a single-center prospective cohort study, 2019-2025, of patients with endogenous hypercortisolism [Cushing syndrome (CS) or mild autonomous cortisol secretion (MACS)] treated with surgery. Associations of demographics, body mass index (BMI), clinical, and biochemical hypercortisolism severity, subtype of hypercortisolism, pre-surgical hypercortisolism duration, glucocorticoid type, and nadir cortisol in relation to duration of AI were investigated. Results The 242 patients [41% MACS, 46% pituitary CS, 12% adrenal CS, 1% ectopic CS, median age 50 years (IQR: 40-60), 85% women] who developed postsurgical AI were followed for a median duration of 13.7 months (IQR 7.2-26.3). The median time to recovery of AI was shorter in MACS vs. overt CS (3.9 months (95% CI: 3.3-6.2) vs. 13.5 months (95% CI 11.3-18.3), P value < .001). On multivariable analysis adjusting for age, sex, BMI, and glucocorticoid type, moderate to severe biochemical severity score (β = 11, P value < .001) and moderate to severe clinical severity score (β=8.7, P < .001), were associated with a longer duration of AI. Conclusions Baseline clinical and biochemical hypercortisolism severity scores may inform individualized counseling on post-operative AI duration in patients treated for CS and MACS.

Objective The purpose of this study was to determine the cumulative incidence of diagnosis switching, drug‐free remission, and initiation of a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD) in individuals with seronegative rheumatoid arthritis (RA). Methods Adult residents of Olmsted County, Minnesota, with incident seronegative (rheumatoid factor negative/anti–cyclic citrullinated peptide antibody negative) RA meeting the 1987 and/or 2010 American College of Rheumatology classification criteria were included. Data were collected from January 1, 2005, to December 31, 2023, through manual chart review. Drug‐free remission was defined as a period of at least six months where the individual was no longer taking treatment for RA and did not have evidence of active inflammatory arthritis upon evaluation by a rheumatologist. We calculated the 10‐year cumulative incidence of a change in diagnosis, adjusting for the competing risk of death, and of drug‐free remission and initiation of a b/tsDMARD, adjusting for the competing risks of death or change in diagnosis. Results A total of 176 individuals with seronegative RA (68% women) were included. The 10‐year cumulative incidence of a change in diagnosis was 12.8% (95% confidence interval [CI] 8.7%–18.9%). The most common change in diagnosis was to spondyloarthritis (4%). The 10‐year cumulative incidence of drug‐free remission and initiation of a b/tsDMARD was 26.6% (95% CI 20.7%–34.2%) and 19.9% (95% CI 14.7%–26.9%), respectively. Over a median follow‐up of 11.8 years, 49 individuals entered drug‐free remission. Conclusion After initial diagnosis of seronegative RA, about 13% of individuals had a change in diagnosis and a quarter experienced drug‐free remission within 10 years.

Background: Data on cognition in patients with primary aldosteronism (PA) are scarce. Mild autonomous cortisol secretion (MACS), defined based on post-dexamethasone cortisol >1.8 mcg/dL, is diagnosed in 20-30% of patients with PA. The impact of MACS on the cognition of patients with PA is unclear. Objectives: 1) to assess cognition in patients with PA versus sex-matched referent subjects with hypertension, 2) determine the differences in cognition of patients with PA (with and without MACS) and patients with MACS. Methods: A cross-sectional study, 2019-2023. Cognition was assessed by National Institute of Health Toolbox Cognition Battery and reported as T-score corrected for age, sex, race, and education. Only subjects with hypertension were included. Results: Cognitive assessment was performed in 52 patients with PA (including 11 patients with both PA and MACS, median age of 51 yrs, 30, 58% women), 47 patients with MACS (median age of 57 yrs, 31, 66% women), and 52 referent subjects (median age of 66 yrs, 30, 58% women). When compared to referents, and after age adjustment, patients with PA had lower cognition: fluid composite cognition β of -6.3 (P=0.014) and total composite of -5.6 (P=0.016). When compared to patients with MACS, and after age and sex adjustment, patients with PA had a similar total composite cognition score (β=3.6, P=0.108) but a higher fluid composite score (β=4.7, P=0.044). No differences in cognition were found between patients with PA with and without MACS, possibly due to low sample size. Conclusion: Patients with PA demonstrate lower cognition when compared to referents with hypertension. Patients with PA had a higher fluid cognition compared to patients with MACS. Future studies should delineate the impact of hyperaldosteronism vs MACS on cognition of patients with PA. Presentation: Monday, July 14, 2025

Objective: To determine the duration of postoperative AI and to identify factors associated with the duration of AI in patients undergoing surgery for endogenous hypercortisolism.Methods: We conducted a single center prospective cohort study, 2019-2024, of patients with endogenous hypercortisolism [Cushing syndrome (CS) or mild autonomous cortisol secretion (MACS)] treated with surgery. Associations of demographics, BMI, clinical and biochemical hypercortisolism severity, subtype of hypercortisolism, presurgical hypercortisolism duration and glucocorticoid type in relation to duration of AI were investigated. Results: The 110 patients [36% MACS, 46% pituitary CS, 15% adrenal CS, 3% ectopic CS, median age 50 years (IQR: 40-60), 82% women] who developed postsurgical AI were followed for a median duration of 26 months (IQR: 15-38). By the end of follow up, 96 patients (87%) had recovery of AI. The median time to recovery of AI was shorter in MACS vs. Overt Cushing syndrome (3.0 months (95% CI: 2.5-6.2) vs. 12.3 months (95% CI 9.0-17.3), P =0.002). Biochemical severity score (r=0.32, P=0.002) and duration of preoperative hypercortisolism symptoms (r=0.29, P=0.005), but not age, sex, BMI, clinical severity, or glucocorticoid type were associated with the duration of AI. We found no differences in the duration of AI between patients with ACTH-dependent vs ACTH-independent CS (12.3 months (95% CI: 6.0-17.2) vs 13.9 months (95% CI: 9.0-25.5), P =0.7).Conclusion: In this interim analysis, we showed that after surgical remission of endogenous hypercortisolism, duration of postoperative AI was longer in CS compared to MACS. Additionally, higher biochemical hypercortisolism severity score and a longer duration of symptoms suggestive of hypercortisolism were associated with a longer duration of postoperative AI.

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

Maus: None. I. Bancos: None. Background: Cortisol secretion follows a circadian pattern with highest concentrations in the morning, and lowest at night. Loss of circadian cortisol variation has been reported in patients with Cushing syndrome (CS), however, is scarcely investigated in patients with mild autonomous cortisol secretion (MACS). Outpatient assessment of late night and early morning salivary cortisol and cortisone may serve as a valuable diagnostic tool in patients with hypercortisolism. Methods: We conducted a single-center cross-sectional study of adults evaluated at our center between 04/2024 and 04/2025. The study included patients with Cushing’s syndrome (CS), mild autonomous cortisol secretion (MACS), and referent subjects without known adrenal disorders. Participants were provided with two cotton swabs (Salivettes) and instructed to collect saliva samples at two standardized time points: at bedtime (PM) and on waking (AM). Each swab was kept in the mouth for 2-2.5 minutes. Saliva was analyzed for cortisol and cortisone using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Delta cortisol and delta cortisone were defined as the difference between AM and PM concentrations for each individual and were calculated for all participants. Results: A total of 82 patients (32 with ACTH-dependent CS, 5 with ACTH-independent CS, and 45 with MACS), median age of 55 years [IQR 44-65], 63 (77%) women, and 71 referent subjects, median age of 34 years [IQR 28-42], 54 (76%) women, were included. Delta cortisol was higher in referents (median of 212 ng/dL, [IQR 157-358]) vs patients with CS (median 95 ng/dL [IQR -21-184]) or MACS (median 131 ng/dL, [IQR 91-229]). Similarly, delta cortisone was also highest in referents with a median of 828 ng/dL [IQR 612-1131] versus median of 211 ng/dL [IQR -58-468] in CS and 484 ng/dL [IQR 189-849] in MACS. When compared to referents in an age- and sex-adjusted linear regression model, delta cortisone was lower in both patients with CS (est -1.3 (95%CI -1.75 to -0.85), P<0.001 and MACS (est -0.66, 95%CI of -1.17 to -0.16, P=0.010). Delta cortisol was lower in patients with CS (est -1.32, 95%CI -2.11 to -0.54, P=0.001), but not MACS (est -0.51, 95%CI -1.39 to 0.36). Conclusion: Patients with both CS and MACS demonstrate a blunted circadian salivary cortisol and cortisone secretion, as reflected by a lower delta cortisol and cortisone when compared to referent subjects. Assessment with delta salivary cortisone in patients with MACS may be more valuable than a standard of care late night salivary cortisol assessment. Presentation: Sunday, July 13, 2025

Background: Bilateral adrenalectomy (BLA) is a seldomly performed treatment for hypercortisolism, pheochromocytoma, or metastatic adrenal disease that leads to permanent primary adrenal insufficiency (PAI). PAI due to BLA is seldomly studied independently of PAI due to autoimmune adrenalitis (AA), despite differences in onset of disease, and neither group has large-scale data focusing on factors that impact quality of life (QOL) post-PAI. Furthermore, no study to date has compared patients’ burden of disease or number of adrenal crises in patients with PAI due to BLA versus patients with PAI due to AA. Methods: We conducted a dual-center, cross-sectional study of adults with PAI due to AA or BLA, 2022-2025. All participants completed a questionnaire on symptoms, management, adrenal crises, and an adrenal insufficiency-specific QoL survey (AddiQoL). Outcomes included AddiQoL scores and self-reported adrenal crises. Pearson correlations were used to explore relationships with AddiQoL scores. Logistic regression models were used to examine associations with having an adrenal crisis in the past year. Results: Of the 343 participants, 203 had AA (median age of 54 years, IQR 42-67, 72% women) and 140 had BLA (median age of 57 years, IQR 44-67, 76% women). Median duration of PAI was similar for AA and BLA cohorts (13 vs 10 years, P=0.205). Patients with AA and BLA were treated with hydrocortisone (84% vs 78%), prednisone (19% vs 21%), or dexamethasone (1% vs 1%), with a similar median daily hydrocortisone equivalent dose (21 mg vs. 20 mg, P=0.259). No group differences in availability of glucocorticoid injections (85% vs 83%) and medical alert bracelet (81 vs 83%) were reported. AddiQoL scores were similar between patients with AA and BLA (median 84 vs 83, P=0.984). AddiQoL score was better in older patients (R=0.16, P=0.003), men (R=0.17, P=0.002), daily hydrocortisone ≤ 20 mg/day (R=0.11, P=0.04), and those with supportive health insurance (R=0.20, P<0.001). Patients with AA reported a higher number of adrenal crises since diagnosis (median of 0.1/person-years, IQR 0-0.4 vs 0/person-years, IQR 0-0.3, P=0.046), as well as in the last year (25% vs 13%, P=0.022), compared to patients with BLA. In a multivariable model of age, sex, glucocorticoid dose, availability of glucocorticoid injection/medical bracelet, type of PAI, and number of symptoms, patients with AA (OR 2.1, 95%CI 1.0-4.4) and those with more symptoms (OR 1.2, 95% CI 1.1-1.3) were more likely to have an adrenal crisis within the last year. Conclusion: We found no differences in the QoL scores, burden of disease, symptoms, or management of patients with AA and BLA. However, patients with AA reported more adrenal crises both overall and within the last year of assessment. Presentation: Sunday, July 13, 2025

Introduction: Studies show that quality of life (QOL) among patients with adrenal insufficiency (AI) (primary (PAI) or secondary (SAI)) improves following adequate glucocorticoid replacement, however decreased QOL persists. SAI due to hypophysitis or infrequently PAI due to adrenalitis are recognized complications of immune-checkpoint-inhibitors (ICI). It is unknown if patients with ICI induced AI (ICI-AI) would report similar findings in QOL. Aim: To assess the impact of ICI-AI on specific determinants of health-related QOL (HRQOL) and compare management and outcomes to SAI due to other etiologies (oSAI). Methods: A cross-sectional survey study of adult patients who completed at least 1 AddiQOL survey with a diagnosis of ICI- AI or oSAI evaluated between 2015 and 2024 were included. Patients with opioid- or glucocorticoid-induced-AI were excluded. A study survey obtained information regarding diagnosis and treatment. Results: 112 patients with ICI-AI were included (SAI n=109, PAI n=3). Among those with ICI-AI, 59% were female, median age at diagnosis was 59.7 ±12.8 years and melanoma was the most common indication for ICI use (51%). The median time to ICI-AI diagnosis was 5.5 (range 0.3-80.8) months and 46% used combination ICI therapy. When compared to those with oSAI (n=139), patients with central ICI-AI were older at diagnosis (59 ±12.7 vs 46 ±18.1 years, p <0.01), more were female (59 vs 43%, p=0.015) and most were diagnosed in the last year (88% vs 42%, p<0.01). Those with ICI-AI received higher hydrocortisone (HC) equivalent daily doses than those with oSAI (25.1± 18.3 vs 22.1 ±16.9 mg/day, p<0.01), however there was no difference in the number of adrenal crises (AC) reported within the last year (14 vs 16, p=0.78). Patients with ICI-AI felt that emergency personnel understood their diagnosis and treated them promptly (75% vs 0% p=0.012). Logistic regression analysis of the entire group (ICI-AI + oSAI) did not identify an association between the occurrence of AC in the last year and HC dose >20 mg/day or type of glucocorticoid. Furthermore, there was no difference in number of AC per person year assessed between the ICI-AI and oSAI (0.23 ±0.5 vs 0.21 ±0.5, p= 0.4). The mean total AddiQOL score was higher in those with ICI-AI (87.2 ±13.9 vs 81.8 ±15.8, p=0.02). When adjusted for age and sex, total AddiQOL score was inversely related to number of symptoms present (r: -0.49, p<0.01; r: -0.58, p<0.01), occurrence of AC in the last year (r: -0.27, p=0.01; r: -0.33, p<0.01) and positively related to current employment (r:0.33 p<0.01 0.2,p=0.02) in ICI-AI and oSAI respectively. Conclusion: This is the first study to compare management and HRQOL in patients with ICI-AI compared to oSAI and although there were no significant differences in total number of AC events between the 2 groups, differences exist in terms of AI presentation, management and reported QOL.

Context: The impact of active hypercortisolism on sleep is incompletely characterized. Several studies report impaired sleep in patients with Cushing syndrome (CS). Patients with mild autonomous cortisol secretion (MACS) demonstrate an abnormal circadian cortisol secretion with mild nocturnal hypercortisolism that could also impact sleep. Objectives: To characterize sleep abnormalities and to identify factors associated with impaired sleep in patients with CS and MACS. Methods: We conducted a single-center cross-sectional study of prospectively enrolled adults with active CS and MACS evaluated between August 31, 2020, and December 2, 2024. Clinical and biochemical severity scores for hypercortisolism were calculated. Quality of life (QoL) was assessed using 1) Short Form-36 (SF-36), physical (PCS) and mental (MCS) component summaries, and 2) Cushing QOL survey, with psychosocial and physical domains. Sleep quality was assessed using Pittsburgh Sleep Quality Index (PSQI), a global score of ≥5 was considered abnormal. Pearson correlations and linear regression models were used to explore associations with PSQI scores. Results: In 285 patients (226 [79%] women, 259 [91%] White, median age of 54 [IQR 44-64] years), MACS was diagnosed in 147 (52%) and CS in 138 (48%). Patients reported abnormal sleep (median PSQI of 12 (IQR 8-16) in CS vs 10 (IQR 7-15) in MACS (P=0.086). Most prevalent sleep abnormalities included report of “fairly bad” or “very bad” overall sleep quality (73% in CS and 54% in MACS) and report of severe day dysfunction due to sleepiness (70% in CS and 56% in MACS). In an age-, sex- and BMI- adjusted univariable analysis of patients with hypercortisolism, higher clinical hypercortisolism severity score (r=0.13, P=0.024) and worse QoL, as measured by SF-36 and Cushing QoL (P=<0.001 for all), were associated with higher PSQI scores, a reflection of poor sleep. In a multivariable analysis of patients with hypercortisolism, we found that younger age (est -0.08, P=<0.001), female sex (est 1.95, P=0.004), lower BMI (est -0.07, P=0.041), and higher clinical severity score (est 0.12, P=0.024) were associated with higher PSQI scores, indicating impaired sleep. In a multivariable analysis of only patients with MACS, female sex (est 2.17, P=0.012), lower BMI (est -0.12, P=0.017), and higher clinical severity score (est 0.24, P=0.003), but not age were associated with higher PSQI scores, indicating impaired sleep. In patients with CS, only younger age (est -0.12, P=<0.001), but not other variables were associated with higher PSQI scores. Conclusion: We found that patients with MACS have impaired sleep, possibly due to nocturnal hypercortisolism. In patients with MACS, but not CS, clinical hypercortisolism severity score was associated with more impaired sleep. Presentation: Sunday, July 13, 2025

Objectives: 1) To characterize sleep abnormalities and to identify factors associated with impaired sleep in patients with MACS. 2) To compare sleep abnormalities between patients with MACS and referent subjects. Methods: We conducted a single-center cross-sectional study of prospectively enrolled adults with MACS evaluated between August 31, 2020, and April 03, 2025. In parallel, we conducted a referent subject study between May 15, 2019, and May 02, 2023. Referent subjects were eligible if they had abdominal cross-sectional imaging without evidence of an adrenal mass. For patients with MACS, clinical and biochemical severity scores for hypercortisolism were calculated. In both groups, quality of life was assessed using Short Form-36 (SF-36), physical (PCS) and mental (MCS) component summaries. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), a global score of ≥5 was considered abnormal. Pearson correlations and linear regression models were used to explore associations with PSQI scores. Results: The total cohort included 167 patients with MACS and 89 referent subjects. No differences in age (median 60 vs 56 years, P= 0.122) and sex (71% vs 67% females, P= 0.523) were observed between patients with MACS and referents. However, median BMI was higher in patients with MACS (32 28 kg/m2 [IQR 28-38] vs 28 kg/m2 [IQR 24-32], P= < 0.001). Patients with MACS had more impaired sleep than referent subjects (median PSQI 11 [IQR 7-15] vs 5 [IQR 3-7], P= <0.001). In an age-, sex- and BMI- adjusted univariable analysis, lower PCS and MCS scores were associated with poor sleep in both referents (r= -0.45, P= <0.001 and r= -0.29, P= 0.008) and patients with MACS (r= -0.36 and -0.38, P= <0.001), however, the presence of obstructive sleep apnea (OSA) was not. In patients with MACS, both higher clinical and biochemical severity scores were associated with poor sleep (r=0.20, P=0.012) and (r= 0.15, P= 0.050). Multivariable analysis of age, sex, BMI, clinical severity and OSA demonstrated that women (est 2.35, P= 0.004), lower BMI (est -0.13, P= 0.014) and higher clinical severity score (est 0.17, P=0.026), but not OSA were associated with impaired sleep in patients with MACS. All PSQI subcomponents were higher in patients with MACS vs referents, indicating poor sleep-most significantly, sleep quality score (OR 3.93, 95% CI: 2.58-6.29), sleep disturbance score (OR 3.73, 95% CI: 2.28-6.37) and daytime dysfunction score (OR 4.74, 95% CI: 2.29-10.75). Conclusion: Patients with MACS report impaired sleep, and women with lower BMI and higher clinical hypercortisolism severity scores are more affected. Reversing abnormal nocturnal hypercortisolism may improve sleep. Presentation: Saturday, July 12, 2025
