Cushing's disease (CD) is caused by a corticotroph adenoma of the pituitary gland that secretes excess adrenocorticotropic hormone (ACTH) causing increased morbidity and mortality. Surgery is the treatment of choice, but is not always successful. Alternatives include radiotherapy, adrenal surgery, and pharmaceutical therapy. The latter is increasingly gaining momentum due to the recent development of compounds that reduce hypercortisolaemia or its symptoms, acting through different mechanisms. Areas covered: In this article, the authors provide a complete overview of the treatment options for Cushing´s disease, including adrenal-directed, tumor-targeted, and peripheral therapies that are currently used or in development, and discuss their potential advantages and limitations...

Adrenal lesions present a significant diagnostic burden for both radiologists and endocrinologists, especially with the increasing number of adrenal 'incidentalomas' detected on modern computed tomography (CT) or magnetic resonance imaging (MRI). A key objective is the reliable distinction of benign disease from either primary adrenal malignancy (e.g., adrenocortical carcinoma or malignant forms of pheochromocytoma/paraganglioma (PPGL)) or metastases (e.g., bronchial, renal). Benign lesions may still be associated with adverse sequelae through autonomous hormone hypersecretion (e...

INTRODUCTION: Crooke's corticotropinomas are the unique cause of Cushing's disease. The majority of them are aggressive macroadenomas, refractory to conventional therapy, with a high recurrence rate. The aim of the study was the presentation, in relation to data from the literature, of a case of a patient with ACTH-dependent Cushing's syndrome caused by recurrent Crooke's cells corticotropinoma, who achieved 33-month complete remission after treatment with temozolomide (TMZ). CASE REPORT: A 54-year-old man was diagnosed with Cushing's disease five years earlier on the basis of a typical clinical picture and hormonal tests...

Cortisol is an important glucocorticoid hormone whose biochemistry influences numerous physiological and pathological processes. Moreover, it is a biomarker of interest for a number of conditions, including posttraumatic stress disorder, Cushing's syndrome, Addison's disease, and others. An implantable biosensor capable of real time monitoring of cortisol concentrations in adipose tissue may revolutionize the diagnosis and treatment of these disorders, as well as provide an invaluable research tool. Toward this end, a mathematical model, informed by the physiological literature, is developed to predict dynamic cortisol concentrations in adipose, muscle, and brain tissues, where a significant number of important processes with cortisol occur...

CONTEXT: Cushing's disease (CD) has a significant relapse rate after successful transsphenoidal surgery (TSS). Many CD patients respond aberrantly to desmopressin testing (DT). Disappearance of this response post-surgery may suggest complete removal of abnormal corticotrophs and lower possibility of recurrence. OBJECTIVE: The utility of post-operative DT to predict long-term outcome compared to the widely used post-operative cortisol (Cort) level. DESIGN: Retrospective analysis...

BACKGROUND: Idiopathic intracranial hypertension (IIH) in patients with Cushing disease (CD), after treatment, is rarely described, in adults. The cause is believed to be multifactorial, potentially related to a relative decrease in cortisol after surgical resection or medical treatment of a corticotroph pituitary adenoma. We investigate our center's CD database (140 surgically and 60 medically [primary or adjunct] treated patients) for cases of IIH, describe our center's experience with symptomatic IIH, and review treatment strategies in adults with CD after transsphenoidal resection...

CONTEXT: In active Cushing's syndrome (CS), patients suffer from endothelial dysfunction and premature atherosclerosis. However, it is uncertain to what extent vascular health recovers after long-term remission. This is highly relevant as this topic relates to future development of cardiovascular disease. OBJECTIVE: To investigate whether micro- and macrovascular health is impaired after long-term remission of CS, in patients with no or adequately treated co-morbidities...

REVIEW
Michael A Mooney, Elias D Simon, Andrew S Little
The current treatment of pituitary adenomas requires a balance of conservative management, surgical resection, and in select tumor types, molecular therapy. Acromegaly treatment is an evolving field where our understanding of molecular targets and drug therapies has improved treatment options for patients with excess growth hormone levels. We highlight the use of molecular therapies in this disease process and advances in this field, which may represent a paradigm shift for the future of pituitary adenoma treatment...

OBJECTIVE: Cushing's disease during pregnancy is associated with an increased risk for maternal and fetal complications. In recurrent Cushing`s disease following transsphenoidal surgery, and when re-operation is not feasible, medical treatment is usually considered. Cabergoline was found to be effective in reducing hypercortisolism in Cushing's disease. Evolving data concerning the safety of cabergoline use during pregnancy show no significant increase in the rate of complications during pregnancy or the postnatal period...

UNLABELLED: Avascular necrosis (AVN) is a rare presenting feature of endogenous hypercortisolism. If left untreated, complete collapse of the femoral head may ensue, necessitating hip replacement in up to 70% of patients. The majority of the described patients with AVN due to endogenous hypercortisolaemia required surgical intervention. A 36-year-old female, investigated for right leg pain, reported rapid weight gain, bruising and secondary amenorrhoea. She had abdominal adiposity with violaceous striae, facial plethora and hirsutism, atrophic skin, ecchymosis and proximal myopathy...

OBJECTIVE: Because magnetic resonance imaging (MRI) fails to detect many adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas, inferior petrosal sinus sampling (IPSS) is considered the gold standard to differentiate Cushing disease (CD) from ectopic ACTH secretion syndrome (EAS). Some authors have suggested internal jugular vein sampling (IJVS) as an alternative to IPSS. METHODS: We simultaneously compared IJVS to IPSS in 30 consecutive patients referred for ACTH-dependent Cushing syndrome and equivocal MRI exams...

OBJECTIVE: The aim of the present study was to describe the quality of life and parenting stress associated with a child with fecal incontinence (FI). METHODS: Female caregivers (n = 170) of children of 3 to 12 years age with FI completed a broad and general measure of quality of life and a measure of parenting stress. Results were compared with proxy reports for a normative sample of healthy children. RESULTS: Caregivers of children with FI reported significantly impaired quality of life for their children and increased parenting stress in all of the respective domains relative to healthy controls...

BACKGROUND: Patients suffering from Cushing's disease are known to be restricted due to a wide range of symptoms. Despite biochemical cure, symptoms might last life-long. These include - among well-known somatic symptoms - several neuropsychiatric symptoms that cannot be as easily tested, but lead to a serious negative impact on quality of life. We aimed to evaluate what factors diminish the self-perceived quality of life the most using 3 questionnaires visualizing those impairments. Furthermore we investigated whether there would be differences in quality of life between patients still being affected by the disease and those that are already in remission...

OBJECTIVE Pituitary MR imaging fails to detect over 50% of microadenomas in Cushing's disease and nearly 80% of cases of dural microinvasion. Surface coils can generate exceptionally high-resolution images of the immediately adjacent tissues. To improve imaging of the pituitary gland, a receive-only surface coil that can be placed within the sphenoid sinus (the endosphenoidal coil [ESC]) during transsphenoidal surgery (TSS) was developed and assessed. METHODS Five cadaver heads were used for preclinical testing of the ESC...

Cushing disease (CD) in children is caused by adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas. Germline or somatic mutations in genes such as MEN1, CDKIs, AIP, and USP8 have been identified in pediatric CD, but the genetic defects in a significant percentage of cases are still unknown. We investigated the orphan G protein-coupled receptor GPR101, a gene known to be involved in somatotropinomas, for its possible involvement in corticotropinomas. We performed GPR101 sequencing, expression analyses by RT-qPCR and immunostaining, and functional studies (cell proliferation, pituitary hormones secretion, and cAMP measurement) in a series of patients with sporadic CD secondary to ACTH-secreting adenomas in whom we had peripheral and tumor DNA (N=36)...

Lichun Sun, David H Coy
Somatostatin (SST) is a cyclic hormone-release inhibitory peptide that has high binding affinity to all of its five SST receptors (SSTRs). SST negatively regulates cell proliferation and the release of multiple hormones via activation of its cognate receptors. A variety of SST analogs, some with high affinity and selectivity of receptor subtypes, have been synthesized and developed. Certain long-acting SST analogs such as octreotide, lanreotide and pasireotide have been clinically applied to the treatment of human diseases such as those caused by excessive release of growth hormone (acromegaly), or adrenocorticotropic hormone (Cushing's syndrome), and for the treatment of carcinoid syndrome...

Cushing's syndrome is a state of cortisol excess, possibly from a tumor in the pituitary gland, the adrenal gland, or an ectopic nonpituitary ACTH-secreting source. The first form, pituitary in origin, was originally described by Harvey Cushing, MD, and was labeled as Cushing's disease. Long-term therapy with glucocorticoids also can lead to iatrogenic Cushing's syndrome.
