Molecular characterization of archival adrenal tumor tissue from patients with ACTHindependent Cushing syndrome.

Cushing syndrome represents a multitude of signs and symptoms associated with long-term and excessive exposure to glucocorticoids. Solitary cortisol-producing adenomas (CPAs) account for most cases of ACTH-independent Cushing syndrome (CS). Technological advances in next-generation sequencing have significantly increased our understanding about the genetic landscape of CPAs.

Hormones synthesized by the adrenal reticulum protect bone density in premenopausal women with Cushing syndrome.

Background: Differences in bone metabolism between patients with adrenal Cushing's syndrome (ACS) and Cushing's disease (CD) have been noted, but the impact of steroid hormones on bone metabolism remains underexplored. The purpose of this study is to explore the differences in bone metabolism between the two subtypes of Cushing's syndrome and the correlation between hormones synthesized by the adrenal reticulum and bone metabolism.

Method: This retrospective study included 75 premenopausal women, consisting of 33 patients with CD and 42 patients with ACS.

Synergistic interplay between cortisol and aldosterone: unveiling mechanisms of vascular calcification in hyperaldosteronism.

The synergistic interplay between cortisol and aldosterone is critical for maintaining homeostasis, particularly in blood pressure regulation, fluid balance, and stress response. Cortisol, a glucocorticoid, and aldosterone, a mineralocorticoid, often act in tandem to regulate sodium retention and blood volume. Dysregulation of these hormones, as seen in hyperaldosteronism or Cushing's syndrome, contributes to hypertension and metabolic imbalances.

Immunochemotherapy for small cell lung cancer with paraneoplastic Cushing syndrome: A case report and literature review.

Rationale: Paraneoplastic Cushing syndrome (PCS) is an adverse prognostic factor for small cell lung cancer (SCLC) patients. Retrospective studies have shown that the median survival of SCLC complicated with PCS was <7 months. No immunochemotherapy has been recorded in the treatment of SCLC with PCS.

Müllerian anomalies and endometriosis: associations and phenotypic variations.

Müllerian anomalies are congenital conditions characterized by the incomplete development of the female reproductive tract. Women affected by Müllerian anomalies often display additional malformations of the renal, skeletal, and cardiovascular system, and are at a higher risk for infertility and adverse pregnancy outcomes. Several Müllerian anomalies have been reported in association with endometriosis, but it is unclear if all classes or anatomical variations are associated with the disease.

Approach to the patient with Cyclical Cushing Syndrome.

Cyclic Cushing's syndrome is a sub-entity of Cushing's syndrome, characterized by repeated episodes of excess cortisol (peaks) followed by spontaneous periods of normal or low cortisol secretion (troughs). Although considered rare, its prevalence reaches 70/514 to 91/514 (14 to 18%) in patients with Cushing's syndrome according to its definition in some reported series and can concern all etiologies of Cushing's syndrome. Physicians should be alert to the presence of cyclical Cushing's syndrome in patients with fluctuating symptoms or where the results of biochemical investigations indicate eu- or hypocortisolism in patients with clinical Cushing's syndrome.

Ultrasonographic adrenal gland changes in dogs with Cushing's syndrome with a low-dose dexamethasone suppression test result consistent with partial suppression or escape pattern.

Background: Cushing's syndrome (CS) in dogs is mainly caused by pituitary-dependent (PDH) or adrenal-dependent (ADH) hypercortisolism. Result of the low-dose-dexamethasone suppression test (LDDST) with partial suppression (PSP) or escape pattern (EP) are indicative of PDH. No data concerning the ultrasonographic characteristics of the adrenal glands from dogs with these patterns exists.

Complicated iatrogenic Cushing's syndrome induced by topical clobetasol propionate in a child with psoriasis: a case report and review of the literature.

Background: Long-term use of oral or parenteral corticosteroids is the most common cause of hypothalamic-pituitary-adrenal axis suppression and iatrogenic Cushing's syndrome. Still, iatrogenic Cushing's syndrome occurs rarely following the administration of topical corticosteroids.

Case Presentation: This case study discusses the misuse of a high-potency corticosteroid cream by an Iranian 5-year-old male with plaque-form psoriasis, resulting in Cushingoid symptoms including moon face, buffalo hump, red striae, and weight gain.

Is there still a place for etomidate in the management of Cushing's syndrome? The experience of a single center of low-dose etomidate and combined etomidate-osilodrostat treatment in severe hypercortisolemia.

Purpose: Severe Cushing's syndrome (SCS) is a life-threatening endocrine condition that requires prompt medical intervention. Intravenous etomidate infusion is considered to be the most effective in rapid cortisol overproduction inhibition. This single-center retrospective study aimed to present the safety and effectiveness of intravenous, low-dose, lipid-formulated etomidate infusion in patients with SCS.

Bone Mineral Density Improvement After Resolution of Endogenous Cushing Syndrome: A Systematic Review and Meta-analysis.

Objective: We aimed to identify all evidence to evaluate bone mineral density (BMD) improvement after resolution of endogenous Cushing syndrome (eCS).

Methods: Potentially eligible studies were identified from the EMBASE and PubMed databases from inception to February 2024, utilizing a search strategy incorporating terms related to "Bone mineral density" and "Cushing syndrome". Eligible studies must include patients diagnosed with eCS.

(Un)Tying the Knot: Oxidative Stress, Inflammatory Markers, and Lipid Status in Dogs with Hypercortisolism.

The aim of this study was to revisit the complex relationship between inflammation, oxidative stress and lipid metabolism in dogs with hypercortisolism (HC). Fourteen dogs newly diagnosed with HC and an equal number of healthy counterparts of similar age and markers of oxidative stress (AOPP, TBARS, TAC, GSH, PON-1, and UA) and inflammation (NLR, PLR, SII, HPT, CHE, CP, and Hcy) were included in the study. To determine the lipid profiles, cholesterol, and triglyceride levels were measured, and the electrophoretic separation of lipoproteins was performed.

Triglyceride-glucose index in patients with non-functioning adrenal incidentaloma, cortisol-secreting adrenal incidentaloma and healthy controls.

Objective: Cushing's syndrome increases the risk of cardiovascular disease. The triglyceride-glucose (TyG) index has been linked to an increased risk of cardiometabolic disorders. Whether patients with non-functioning adrenal incidentaloma (NFAI) or cortisol-secreting adrenal incidentaloma (CSAI) have altered TyG index is unknown.

Cardiovascular risk improvement after laparoscopic adrenalectomy in patients with cortisol-secreting adrenal adenoma, a retrospective cohort study.

Background: Cushing syndrome increases morbidity and mortality, which is mainly caused by cardiovascular disorders. This study reports the cardiovascular risk outcomes at 3, 6, and 12 months after unilateral laparoscopic adrenalectomy in cortisol-secreting adrenal tumor and to identify the preoperative parameters predicting the resolution of cardiovascular risk factors after surgery.

Methods: All clinical data of patients with unilateral cortisol-secreting adrenal tumors who underwent laparoscopic adrenalectomy in King Chulalongkorn Memorial Hospital between 2001-2022 were retrospectively reviewed.

Glucocorticoid replacement therapy after retroperitoneal laparoscopic unilateral adrenal adenoma resection in patients with non-cortisol secreting tumors: a retrospective cohort study.

Background: Adrenal Cushing's syndrome is caused by an adrenal tumor that produces hypercortisolism and requires glucocorticoid supplementation following resection of the tumour to prevent adrenal insufficiency. Few studies have examined whether glucocorticoid replacement (GR) therapy is required after retroperitoneal laparoscopic unilateral adrenal adenoma resection in patients with non-cortisol secreting tumors, or whether there is any correlation between preoperative biochemical indicators and postoperative cortisol function. This study sought to investigate which patients with non-cortisol secreting tumors required GR therapy after undergoing retroperitoneal laparoscopic resection of unilateral adrenal cortical adenoma.

Synchronous bilateral adrenalectomy for ACTH-independent Cushing's syndrome in children: multidisciplinary management.

Objective: ACTH-independent Cushing's syndrome (CS) in children is very rare but potentially fatal. In bilateral nodular hyperplasia, synchronous bilateral adrenalectomy (SBA) represents the definitive treatment to correct hypercortisolism. We aim to report the multidisciplinary management of this rare condition.

Lateralization outcomes of bilateral inferior petrosal sinus sampling: desmopressin vs CRH.

Purpose: Bilateral inferior petrosal sinus sampling (BIPSS) is the gold standard for localizing ACTH-dependent Cushing's syndrome (CS). While corticotropin-releasing hormone (CRH) was initially used for stimulation, desmopressin has become a common alternative. This research evaluates desmopressin's effectiveness in lateralizing Cushing's disease (CD) during BIPSS compared to CRH stimulation.

Ectopic corticotropin-releasing hormone syndrome caused by rectal large cell neuroendocrine carcinoma: a rare case report.

Ectopic corticotropin-releasing hormone (CRH) syndrome, a rare subtype of adrenocorticotropic hormone-dependent Cushing syndrome, is associated with tumors of diverse origins. Here, we present a case of a 37-year-old female diagnosed with ectopic CRH syndrome secondary to rectal large cell neuroendocrine carcinoma, a hitherto unprecedented site for CRH-secreting tumors. The patient presented with classical features of Cushing syndrome, supported by laboratory evidence of hypercortisolemia and disrupted diurnal cortisol secretion.

Growth hormone/insulin-like growth factor I axis in health and disease states: an update on the role of intra-portal insulin.

Growth hormone (GH) is the key regulator of insulin-like growth factor I (IGF-I) generation in healthy states. However, portal insulin delivery is also an essential co-player in the regulation of the GH/IGF-I axis by affecting and regulating hepatic GH receptor synthesis, and subsequently altering hepatic GH sensitivity and IGF-I generation. Disease states of GH excess (e.

Complete Tumor Resection and Radical Lymphadenectomy: Potential Cure for Adrenocorticotropic Hormone (ACTH)-Dependent Pulmonary Carcinoid.

Ectopic adrenocorticotropic hormone (ACTH)-dependent Cushing is a rare syndrome. We present a case that illustrates the diagnostic and therapeutic challenges of ectopic Cushing. A 35-year-old woman presented to the outpatient clinic for evaluation of progressive weight gain, muscle weakness, easy bruising, uncontrolled hypertension, and hyperglycemia.

Autophagy-dependent hepatocyte secretion of DBI/ACBP induced by glucocorticoids determines the pathogenesis of cushing syndrome.

DBI/ACBP is a phylogenetically ancient hormone that stimulates appetite and lipo-anabolism. In response to starvation, DBI/ACBP is secreted through a noncanonical, macroautophagy/autophagy-dependent pathway. The physiological hunger reflex involves starvation-induced secretion of DBI/ACBP from multiple cell types.

Addisonian Pigmentation - The Great Mimicker - A Review.

Skin colour usually depends upon melanin, haemoglobin, and carotenoids. Pigmentary disorders indicate an increased amount of melanin, leading to a darker colour of the skin, called hypermelanosis. Addison's disease is a rare endocrinal disorder with severe oral and systemic manifestations.
