Filter by:Cushing's disease is a rare disease that can reduce patients' expectations or quality of life, and for which predictive factors for cardiovascular mortality and recurrence are not well defined. The primary objective is to determine the rates of remission and recurrence of patients with Cushing's disease diagnosed between 1990 and 2015 in the French region of the West (Angers, Brest, Nantes, Rennes, Poitiers , Tours) focusing on remission particularly at two periods : that after the first pituitary surgery and that on the day of the last news. The secondary objective is to study the possible prediction of clinical and biological data perioperative of remission and recurrence during follow-up.
Background: Pasireotide treatment is strictly associated with glucose metabolism impairment. The aim of the study was to evaluate the effect of pasireotide on β -cell and adipose function in patients with Cushing's disease (CD). Methods: Clinical and hormonal parameters, insulin secretion, evaluated by homostasis model assessment (HOMA-β) and by the area under the curve (AUC2h) of C-peptide during a mixed meal tolerance test and insulin sensitivity, evaluated by the euglycemic hyperinsulinemic clamp, were evaluated in 12 patients with active CD before and after 12 months of pasireotide. Circulating adipokines were evaluated in patients with CD compared to a matched group of 12 diabetic patients.
The purpose of this study is to study since 1987 all patients diagnosed with CD in Sweden and determine their outcomes including mortality. A secondary objective is to focus on patients in remission and identify determinants of their different outcomes.
Cushing syndrome refers the manifestations induced by chronic glucocorticoid excess and may arise from various causes. Iatrogenic Cushing syndrome accounts for most patients, when they are given exogenous glucocorticoid treatment. In contrast, spontaneous Cushing syndrome results from endogenous glucocorticoid over-secretion. Although Cushing disease is rare, it is the most common cause of spontaneous Cushing syndrome. The patient with Cushing disease has a pituitary corticotroph adenoma, which overproduces adrenocorticotropic hormone (ACTH). ACTH then stimulates adrenal gland to over-secret glucocorticoid. Patients with untreated Cushing disease were shown to have poor prognosis, estimated a 5-year survival rate of 50%. The first line treatment is tumor resection. Other managements include radiotherapy, medication and bilateral adrenalectomy. The initial remission rate is high (66-90%). However, some patients encounter with disease recurrence during follow-up. The aim of this study is to clarify the factors associated with the recurrence after treatment. In this study, we will review the patients with Cushing disease thoroughly and analyze associated predisposing factors. These risk factors can remind the clinical physician to early detect the recurrent disease in these patients, and further prevent morbidity and mortality in their later lives.
This exploratory study is a proof of concept study to determine whether LCI699 can safely reduce the level of urinary free cortisol in patients with Cushing's disease. In addition, this study evaluated the long term efficacy and safety of LCI699 including an additional 12 week of treatment followed by a 12 month long term optional extension. A second extension provided patients who were clinically benefitting from LCI699 an opportunity to continue to have access to the drug until LCI699 was commercially available and reimbursed or through the availability of a local access program.
Cushing's disease is a rare serious condition that is caused by an adrenocorticotropic hormone (ACTH) secreting pituitary adenoma. This study assessed the long-term safety and efficacy of pasireotide in participants with Cushing's disease.
There is a variety of tumors affecting the pituitary gland in childhood; some of these tumors (eg craniopharyngioma) are included among the most common central nervous system tumors in childhood. The gene(s) involved in the pathogenesis of these tumors are largely not known; their possible association with other developmental defects or inheritance pattern(s) has not been investigated. The present study serves as a (i) screening/training, and, (ii) a research protocol. As a screening and training study, this protocol allows our Institute to admit children with tumors of the hypothalamic-pituitary unit to the pediatric endocrine clinics and wards of the NIH Clinical Center for the purposes of (i)<TAB>training our fellows and students in the identification of genetic defects associated with pituitary tumor formation, and (ii)<TAB>teaching our fellows and students the recognition, management and complications of pituitary tumors As a research study, this protocol aims at (i)<TAB>developing new clinical studies for the recognition and therapy of pituitary tumors; as an example, two new studies have emerged within the context of this protocol: (a) investigation of a new research magnetic resonance imaging (MRI) tool and its usefulness in the identification of pituitary tumors, and (b) investigation of the psychological effects of cortisol secretion in pediatric patients with Cushing disease. Continuation of this protocol will eventually lead to new, separate protocols that will address all aspects of diagnosis of pituitary tumors and their therapy in childhood. (ii)<TAB>Identifying the genetic components of pituitary oncogenesis; those will be investigated by (a) studying the inheritance pattern of pituitary tumors in childhood and their possible association with other conditions in the families of the patients, and (ii) collecting tumor tissues and examining their molecular genetics. As with the clinical studies, the present protocol may help generate ideas for future studies on the treatment and clinical follow up of pediatric patients with tumors of the pituitary gland and, thus, lead to the development of better therapeutic regimens for these neoplasms.
