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 The impact of active hypercortisolism on sleep is incompletely characterized. Studies report impaired sleep in patients with Cushing syndrome (CS). Patients with mild autonomous cortisol secretion (MACS) demonstrate mild nocturnal hypercortisolism that could impact sleep. Objectives To characterize sleep abnormalities in patients with CS and MACS using the Pittsburgh Sleep Quality Index (PSQI), identify factors associated with poor sleep, and compare sleep abnormalities in patients with MACS vs referent subjects. Methods We conducted a single-center cross-sectional study of adults with active CS and MACS. Clinical and biochemical severity scores for hypercortisolism were calculated. Parallelly, we enrolled referent subjects. Quality of life was assessed using (1) the Short Form-36 (SF-36) in all participants and (2) the CushingQoL in patients with active hypercortisolism. Sleep quality was assessed using PSQI. Results PSQI was assessed in 154 patients with CS (mean 12, SD ±4.5), 194 patients with MACS (mean 11, SD 4.6), and 89 referents (mean 5, SD ±3.4). Patients with MACS exhibited shorter sleep duration, longer sleep latency, more severe daytime dysfunction, lower sleep efficiency, and a higher sleep medication use compared to referent subjects (P = <.001 for all). Age-, sex, and body mass index-adjusted analysis demonstrated no differences in PSQI or its subcomponents between patients with CS and MACS (P > .05 for all). In a multivariable analysis of patients with MACS, younger age, female sex, and higher clinical hypercortisolism severity score were associated with impaired sleep. In patients with CS, only younger age was associated with poor sleep. Conclusion Patients with MACS demonstrate sleep impairment that is similar to patients with CS. Younger women with higher clinical severity of MACS are more likely to have impaired sleep.

Abstract Background Mitotane monotherapy is the standard adjuvant treatment for adrenocortical carcinoma (ACC), yet reliable predictors of treatment response remain lacking. Given the well-recognized interplay between inflammation and cancer progression, serum inflammation-based scores have shown prognostic significance in various malignancies, including ACC in palliative settings. However, their relevance during adjuvant mitotane therapy remains uncertain. This study aimed to assess the prognostic value of inflammation-scores in patients with ACC receiving adjuvant mitotane. Methods Multicenter ENSAT retrospective study including patients with ACC treated with adjuvant mitotane as first-line therapy. Clinical data including age, sex, ENSAT tumor stage, Ki67 index, resection status, and hormone secretion were collected at diagnosis. Inflammation-scores - neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), systemic immune inflammation index (SII), and pan-immune-inflammation value (PIV) - were calculated at diagnosis (pre-surgery) and at mitotane start. Median values of inflammation-scores at diagnosis defined low and high levels. Overall survival (OS) and time to progression (TTP) from mitotane start were the primary endpoints. Results The study included 395 patients (66% female; median age: 51 years). Median time to mitotane start was 54 days (IQR: 32–90). At diagnosis, patients with glucocorticoid excess (n=84) had significantly higher inflammation-scores than those without (n=104): NLR (3.61 vs 2.53), dNLR (2.31 vs 1.72), SII (864.1 vs 679.3), and PIV (531.6 vs 343.1); all p≤0.005. All scores significantly declined after surgery (p<0.05). Higher inflammatory scores at diagnosis were associated with worse OS (NLR: HR=3.85, 95%CI=1.95–7.59, p<0.001; dNLR: HR=3.19, 95%CI=1.67- 6.08, p<0.001; SII: HR=1.97, 95%CI = 1.07–3.61, p=0.03; PIV: HR=2.11, 95%CI=1.13-3.95, p=0.02). However, only the NLR and dNLR remained independently associated with OS at multivariate analysis adjusted for ENSAT stage, Ki67 index, and resection status (p<0.05). At mitotane start (n=372), high SII and PIV were associated with shorter TTP (SII: HR=1.36, 95%CI=1.02-1.82, p=0.03; PIV: HR=1.40, 95%CI=1.04-1-87, p=0.02), with only SII remaining significant at multivariate regression (p=0.04). Conclusions Inflammation-based scores are higher in patients with glucocorticoid excess and decrease postoperatively. NLR and dNLR at diagnosis, and SII at mitotane start, are associated with clinical outcomes in patients with ACC receiving mitotane adjuvant monotherapy. These readily available markers may help improve prognostic stratification in clinical practice.

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 Objective The objective of this study is to identify social/metabolic risk factors associated with subsequent diagnosis of adrenal adenoma Design The design is a population-based historical case–control study. Methods Cases were adult patients diagnosed with an adrenal adenoma between 2005 and 2017 with no overt hormone excess. Controls were age- and sex-matched individuals with (1) no diagnosis of adrenal adenoma and (2) no diagnosis of adrenal adenoma with cross-sectional imaging of the chest/abdomen performed within 5 years prior to index date. The frequency of various social/metabolic risk factors present 5-10 years prior to index date and odds ratios (ORs) for adrenal adenoma diagnosis were reported. Results Six hundred seventy cases identified (median age 63 years old, 56% women). During the 5-10 years prior to index date, patients with adrenal adenomas had higher prevalence of obesity (56.7% vs 49.3%, P = .007), low socioeconomic status (36.7% vs 31.1%, P = .039), tobacco use (70.2% vs 61.4%, P = .001), and diabetes (17.5% vs 11.7%, P = .003) compared to controls with prior imaging. No difference in prevalence of hypertension, substance use, chronic kidney disease, or combined cardiovascular events was observed. Based on a multivariable analysis, increased body mass index (BMI) and tobacco use were associated with increased odds of adrenal adenoma diagnosis with ORs 1.18 (95% confidence interval [CI] 1.07-1.32) and 1.41 (95% CI 1.06-1.87), respectively. Conclusions Compared to controls with prior imaging, patients with adrenal adenoma had higher prevalence of obesity, low socioeconomic status, tobacco use, and diabetes 5-10 years prior to index date. In particular, increased BMI and tobacco use were independent risk factors associated with increased odds of adrenal adenoma diagnosis.

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.

OBJECTIVE Patients with growth hormone (GH)–secreting pituitary adenomas (PAs) experience various symptoms and comorbidities, which can ultimately lead to increased mortality. This study aimed to develop and validate a machine learning (ML) model for predicting long-term outcomes in patients with GH-secreting PAs following endonasal transsphenoidal surgery (ETS). METHODS The authors conducted a retrospective three-institution cohort study that included patients with GH-secreting PAs treated with ETS between 2013 and 2023. Clinical, radiological, and biochemical data were collected. The main outcome of interest was the intervention-free rate (IFR) after primary ETS. Supervised ML algorithms, including decision trees and random forests, were developed to predict the IFR. Model performance was evaluated using area under the receiver operating characteristic curve (AUROC) and Shapley Additive Explanations (SHAP) values. RESULTS The median follow-up for 100 patients with GH-secreting PAs (53% female) was 64 months (range 1–130 months). Additional intervention for persistent or recurrent acromegaly was required in 32% of patients. Following primary ETS alone, the 3-year IFR was 70% and the 5-year IFR was 67%. Multiple ML models were developed and evaluated using AUROCs. The decision tree analysis achieved an accuracy of 81% and emphasized the importance of both gross-total resection (GTR) and patient age in determining the long-term IFR. To better understand the factors that contributed to model performance, SHAP analysis was applied to the best-performing model. The SHAP dependence plots showed that key factors associated with a longer IFR included tumor size < 9 mm, GTR, patient age > 65 years, and Knosp grade 0. CONCLUSIONS This ML model offers a more nuanced and potentially more accurate approach to identify patients more likely to develop recurrent or persistent acromegaly following primary ETS and require additional treatment. Following external validation, this ML model could improve personalized treatment planning and follow-up strategies and enhance patient care and resource allocation in clinical practice.
