Four Studies that Can Improve Patient Outcomes Since April is Adrenal Disease Awareness Month, Endocrine News is highlighting recent studies that shed light on important advances and insights in the field. These studies, all published in Endocrine Society journals, show how improved diagnostic accuracy, postoperative management, and a better understanding of rare adrenal pathologies offer clinicians tools that could improve patient outcomes.
At a Glance • The CAI score improves diagnostic accuracy in ambiguous cases of suspected central adrenal insufficiency (CAI) by integrating morning serum cortisol with key clinical parameters and can help guide treatment decisions. • Two-pronged testing consisting of basal cortisol and cosyntropin levels initiated as early as four weeks post-adrenalectomy can identify patients with adrenal insufficiency, guide glucocorticoid treatment, and obviate unnecessary glucocorticoids.
• Although typically benign and nonsecretory, adrenal ganglioneuromas (AGNs) can rarely exhibit secretory properties that mimic other adrenal pathologies, making definitive histopathologic assessment essential; in cases of ACTH-dependent hypercortisolism with an adrenal lesion, secretory AGN should remain on the differential.
Integrated assessments that combine biochemical data, clinical features, imaging, and, when available, post-surgical trajectories are emphasized as more informative for guiding subsequent steps in workup, management, and follow-up.
The material also underscores the ongoing need for standardization, external validation of novel tools, and longitudinal data to refine practice.
The intention was to provide a more nuanced risk stratification to determine the necessity of dynamic testing.
The short Synacthen test (SST) served as the reference standard for CAI diagnosis.
A machine learning model underpins the scoring system, which is accessible via a web-based application.
Rather than the conventional 3–15 µg/dL span, they modeled the range from 4 to 18 µg/dL to reflect real-world lab variability and to capture differentiated risk as cortisol levels vary within that interval.
Specifically, having three or more additional hormone deficits emerged as a powerful predictor of CAI, with an odds ratio exceeding 35, underscoring that CAI commonly coexists with broader pituitary dysfunction.
It is not presented as a replacement for clinical judgment.
The authors acknowledge that broader validation and demonstration of workflow integration are prerequisites for widespread uptake.
By integrating multi-domain data and employing an adaptable framework that accommodates lab variability, the CAI score aligns with contemporary moves toward data-driven, personalized decision-making in endocrinology.
institutions.
The analysis compared two postoperative cortisol testing modalities: basal (basal cortisol) versus cosyntropin stimulation testing (CST).
The authors suggest that younger individuals might harbor more biochemically active or prolonged cortisol autonomy, contributing to deeper HPA suppression.
This approach is proposed to minimize unnecessary prolonged glucocorticoid exposure and to facilitate timely, individualized management.
They note that while developing a preoperative risk score is conceptually feasible, it would not eliminate the necessity for postoperative biochemical assessment.
The team also highlights the need to explore mechanistic explanations for age-related differences and to standardize postoperative testing protocols across centers.
It emphasizes that timing and modality of testing influence clinical decision-making and patient safety.
Section 4: Hidden Players in Adrenal Pathology: Rare Presentations with Critical Lessons
The patient presented with hypertension, an adrenal mass on the right, anxiety, and diaphoresis, with biochemical evidence of ACTH-dependent hypercortisolism.
Surgical resection yielded a histopathologic diagnosis of pure AGN with ACTH immunostaining confirming ACTH production.
This case reinforces the importance of definitive histopathologic assessment to establish diagnosis in this domain.
Genetic testing confirmed a MEN1 mutation.
Despite surgical management (adrenalectomy and distal pancreatectomy), the patient succumbed to postoperative sepsis and septic shock, with Cushing syndrome contributing to increased susceptibility to infection.
The authors emphasize the value of genetic testing and familial screening for early detection and preventive strategies, which can influence surveillance planning and potentially improve outcomes.
The potential for ACTH production by an adrenal ganglioneuroma expands the differential when confronted with ACTH-dependent hypercortisolism and an adrenal lesion.
The reports collectively advocate for comprehensive hormonal evaluation and consideration of genetic etiologies when clinical features suggest multisystem endocrine involvement.
The reports also emphasize structured genetic counseling and testing as integral components of care in MEN1-associated adrenal disease.
The narrative highlights that routine genetic testing and family screening in MEN1 can inform surveillance strategies and potentially alter outcomes by enabling earlier intervention.
They instead illustrate the clinical heterogeneity and the functional consequences of adrenal disturbances, emphasizing diagnostic precision and timely intervention as potential drivers of improved outcomes.
