Pituitary carcinomas are rare and aggressive neoplasms that despite current treatment regimens continue to have a poor prognosis. Adrenocorticotrophic hormone (ACTH) pituitary tumors have been shown to alter their clinical manifestations with conversion to Cushing's disease and silent types. The purpose of this paper is to present the first documented case of an ACTH secreting pituitary adenoma with Cushing's disease that differentiated into a silent corticotroph pituitary carcinoma with metastases to dista...
Cushing's disease is a rare systemic and disabling disease due to oversecretion of adrenocorticotrophic hormone (ACTH) resulting in excess cortisol levels. Diagnosis and treatment are difficult; despite the availability of various pharmaceutical treatment options, there is an ongoing, unmet need for even more effective treatment. Areas covered: The present review aims at providing an overview of available drugs and presenting new developments. Focusing on the pituitary as a target, the review covers compoun...
Thyrotropin (TSH)-secreting pituitary tumors are the rarest functioning pituitary tumors. Nonetheless, they are not infrequently plurihormonal, as they may express/secrete hormones made by other pituitary cells derived from the Pit-1 lineage such as growth hormone (GH), prolactin (PRL), and α-subunit (αSU). However, adrenocorticotropin (ACTH) or gonadotropin secretion by such a tumor is exceptional. Although double pituitary tumors are rare, they often combine ACTH and GH secretion. A 41-year-old presente...
In most clinical series of Cushing's disease (CD), over 80% of patients are women, many of whom are of reproductive age. The year following pregnancy may be a common time to develop CD. We sought to establish the incidence of CD onset associated with pregnancy.
Background Cushing's disease (CD) represents the principal cause of endogenous hypercortisolism. The first-line therapy of CD is surgical removal of the ACTH secreting pituitary adenoma, which is generally followed by adrenal insufficiency (AI). Objective To analyse the recovery of the AI in patients with CD after pituitary surgery in relation with recurrence and persistent remission of CD. Materials and Methods Retrospective analysis on patients with CD who met the following inclusion criteria: adult age, ...
Equine Cushing's Disease (Pituitary pars intermedia dysfunction (PPID)) is a common condition of older horses but its pathophysiology is complex and poorly understood. In contrast to pituitary-dependent hyperadrenocorticism in other species, PPID is characterised by elevated plasma ACTH but not elevated plasma cortisol. In this study, we address this paradox and the hypothesis that PPID is a syndrome of ACTH excess in which there is dysregulation of peripheral glucocorticoid metabolism and binding. In 14 PP...
ACTH-secreting pituitary adenomas give rise to a severe endocrinological disorder, i.e., Cushing's disease, with multifaceted clinical presentation and treatment outcomes. Experimental studies suggested that disease variability is inherent to the pituitary tumor, thus pointing to the need for further studies into tumor biology. Aim of the present study was to evaluate transcriptome expression pattern in a large series of ACTH-secreting pituitary adenoma specimens, in order to identify molecular signatures o...
This study investigated the outcome of transsphenoidal surgery for Cushing's disease and the influence of our surgical strategy on remission rates and postoperative pituitary function.
The primary treatment of choice for Cushing's disease (CD) is the removal of the pituitary adenoma by transsphenoidal surgery (TSS). The surgical failure is seen in up to 75% of cases depending on the experience of the surgeon in different studies. Medical therapy is one of the options for the treatment of recurrent or persistent CD.
Cushing's syndrome (CS) or hypercortisolism results from disruption of the hypothalamus-pituitary-adrenal (HPA) axis with the resultant increase in the circulating serum and urinary cortisol levels and lack of cortisol circadian rhythm. The resultant effects cause the physical manifestation of hypercortisolism. The appearance of Cushing's disease in children is insidious, the most common features being growth failure, obesity, early puberty and facial appearance. We report a case of a 7-year-old male with a...
Despite advances in diagnostic and therapeutic approach, Cushing's disease (CD) presents a challenging situation for the treating physician.
Cushing syndrome (CS) is a rare disease in children, frequently associated with subtle or periodic symptoms that may delay its diagnosis. Weight gain and growth failure, the hallmarks of hypercortisolism in pediatrics, may be inconsistent, especially in ACTH-independent forms of CS. Primary pigmented nodular adrenocortical disease (PPNAD) is the rarest form of ACTH-independent CS, and can be associated with endocrine and nonendocrine tumors, forming the Carney complex (CNC). Recently, phenotype/genotype cor...
Primary bilateral macronodular adrenal hyperplasia is an uncommon cause of endogenous Cushing's syndrome characterized by the presence of aberrant adrenal expression of ectopic receptors that regulate steroidogenesis by mimicking the events triggered by ACTH receptor activation. Receptors of this type have been described for several hormones. The aim of the study is to detect these receptors in two patients with ACTH-independent hypercortisolism by means of the application of a screening protocol.
Silent pituitary adenomas are anterior pituitary tumors with hormone synthesis but without signs or symptoms of hormone hypersecretion. They have been increasingly recognized and represent challenging diagnostic issues.
Ca2+ influx through voltage-gated Ca2+ channels (VGCCs) plays a key role in the secretion of growth hormone (GH). In this review, we summarize the current state of knowledge regarding the physiology and molecular machinery of VGCCs in pituitary somatotrophs. We next discuss the possible involvement of Ca2+ channelopathies in pituitary disease and the potential usage of Ca2+ channel blockers in the treatment of pituitary disease. Various types of VGCCs exist in pituitary cells. However, since L-type Ca2+ cha...
Pasireotide has been associated with tumor shrinkage in patients with Cushing's disease subjected to long term treatment. However, to date the implicated molecular mechanisms are poorly elucidated. Here, we tested pasireotide-mediated cytostatic and cytotoxic effects in ACTH-secreting primary tumor cultures and murine corticotroph tumor cell line, AtT-20 cells. We found somatostatin receptor type 5 (SST5) expressed in 17 different ACTH-secreting tumors and SST2 detectable in 15 out of the 17 tissues. Pasi...
This case report describes a 35-year-old Caucasian man who was referred to the glaucoma clinic with high intraocular pressure (IOP) after routine optometrist assessment. He was diagnosed with ocular hypertension (OHT) and the management plan was for monitoring without treatment. Three months later, he presented to the endocrine clinic with symptoms of Cushing's disease and was diagnosed with an adrenocorticotropic hormone secreting pituitary microadenoma. His symptoms preceded his presentation at both depar...
The diagnosis of pituitary carcinoma is very rare, requires the evidence of metastatic disease, and has a poor overall survival. Malignant prolactinoma frequently requires dopamine agonist therapy, pituitary surgery, radiotherapy, and even chemotherapy.
β-Human chorionic gonadotropin (β-HCG) is an embryonic protein secreted by the syncytiotrophoblast of the placenta. The determination of the plasma β-HCG level is routinely used for the diagnosis and the follow-up of germ cell tumors. Some adenocarcinomas have been described as being rarely associated with β-HCG hypersecretion. We report a case of gastric signet-ring cell carcinoma with β-HCG hypersecretion and propose hypotheses to explain the pathogenesis of such hypersecretion.
somatic mutations in the ubiquitin-specific protease 8 (USP8) gene have recently been described in patients with Cushing's disease (CD). The aim of the study is to verify whether USP8 mutation may predict early and late outcome of pituitary surgery in patients with CD operated at a single institution.
Ectopic Cushing syndrome constitutes approximately 10% of all patients with Cushing syndrome. The clinical features of hypercortisolism result from elevated levels of adrenocorticotropic hormone produced by a tumor. The present case presented with clinical and biochemical parameters suggestive of Cushing syndrome with normal pituitary and adrenals on imaging. Ga-DOTANOC PET/CT done to localize an ectopic adrenocorticotropic hormone-producing tumor revealed metastatic medullary carcinoma of the thyroid as th...
To investigate whether low-dose mitotane (up to 2 g/day) could be a temporary therapeutic alternative to transsphenoidal surgery (TSS) in pediatric Cushing's disease (CD).
Elevated midnight cortisol levels induced by non-suppressed ACTH levels may lead to false-positive results for hypercortisolism in patients with adrenal incidentaloma. We investigated whether plasma ACTH-associated high midnight serum cortisol levels are correlated with other endocrinological findings with respect to hypothalamic-pituitary-adrenal function or hypercortisolism status.
Patients with non-functioning pituitary adenomas exhibit high morbidity and mortality rates. Growth hormone deficiency and high doses of glucocorticoid substitution therapy have been identified as corresponding risk factors. Interestingly, high levels of endogenous cortisol in, e.g., patients with post-traumatic stress disorder or patients with Cushing's disease have been linked to shorter telomere length. Telomeres are noncoding DNA regions located at the end of chromosomes consisting of repetitive DNA seq...
