Filter by:The goal of this observational study is to evaluate, retrospectively and prospectively, the effect of different hormonal and neuropeptide dysfunctions on the body composition of patients suffering from hypothalamic-pituitary pathologies, and to evaluate the potential beneficial effect of surgical and medical treatments with agonists and antagonists of hypothalamic neuropeptides, currently available, on the development and treatment of adiposity and negative cross-talk between adiposity and muscle/bone tissue
Osteoporosis is a chronic skeletal disease which leads to a decrease in bone strength which increases the risk of fractures. Clinically overt hypercortisolism leads to hypertension, central obesity, diabetes and osteoporosis. More recently, even the condition of mild and asymptomatic hypercortisolism has been associated with increased prevalence of chronic complications of cortisol excess and mortality. In patients with osteoporosis this form of hypercortisolism may remain occult (hidden hypercortisolism, HidHyCo). Although asymptomatic, however, this subtle cortisol excess is associated with an increased risk of osteoporosis and fragility fractures. Moreover, HidHyCo prevalence seems to be increased in osteoporotic patients. The HidHyCo case finding is of utmost importance. However, given the high prevalence of bone fragility and the relatively low diagnostic accuracy of the currently available tests for the HidHyCo detection, a mass screening for HidHyCo is considered unthinkable. As now, no guidelines are available for addressing the HidHyCo screening in osteoporosis. Therefore, the aims of the present study are the following: i) to assess the HidHyCo prevalence in a sample of osteoporotic patients; ii) to compare the clinical characteristics between osteoporotic/osteopenic patients with HidHyCo and those without HidHyCo in order to determine the clinical characteristics more frequently associated with the HidHyCo presence and to identify those osteoporotic patients worthy of HidHyCo screening; iii) to further investigate bone quality and turnover in HidHyCo patients, to characterize HidHyco patients from a molecular and genetic point of view and to evaluate the pathogenetic mechanisms explaining the negative effects of endogenous cortisol excess on bone health in these patients and the potential role of the genetic background and of the gut microbiome. The HidHyCo could be present in a not negligible percentage of osteopenic/osteoporotic patients. In these patients, osteoporosis and, if present, other comorbidities can improve by the surgical resection of the adrenal or pituitary adenoma if feasible, or by the use of drugs able to modulate cortisol secretion or glucocorticoid sensitivity. Moreover, the case-finding could be reserved in those patients at higher risk of having HidHyCo, therefore, reducing the costs of a scarcely specific mass screening.
The goal of this clinical trial is to exploring the role of tubeless after adrenalectomy surgery. The main questions it aims to answer are: 1. The safety of tubeless laparoscopic adrenalectomy； 2. The role of tubeless therapy in rapid recovery after adrenalectomy surgery Participants will be randomly divided into two groups: the non drainage group and the drainage group after laparoscopic adrenal surgery, and their pain, first time out of bed, and intestinal recovery time will be observed.
Background: The adrenal glands are 2 small organs that sit on top of each kidney. They release hormones; these are chemicals that control how the body works. Tumors on or outside the adrenal glands are called functional if they release hormones; they are called nonfunctional if they do not. Doctors who treat adrenal tumors need to know which type a person has. Researchers want to find better ways to learn whether an adrenal tumor is functional. Objective: To see if a new radioactive tracer ([68Ga]Ga-PentixaFor) can make it easier to identify functional adrenal tumors with positron emission tomography (PET) scans. Eligibility: People aged 18 years and older with 1 or more adrenal tumors. They must have increased levels of the hormones aldosterone or cortisol. They must also be enrolled in at least 1 other related NIH study (protocols 19-DK-0066, 18-CH-0031, or 09-C-0242). Design: Participants will be screened. They may have imaging scans. Their ability to perform normal activities will be reviewed. Participants will have one PET scan with the study tracer. The tracer will be given through a tube attached to a needle inserted into a vein. Participants will receive the tracer 1 hour before the scan. They will lie still on a bed while a machine captures images of the inside of their body. The scan will take 45 to 90 minutes. Participants heart rate, blood pressure, and rate of breathing will be checked before, during, and after the scan. Participants will have a follow-up visit 3 days after their scan. This visit can be by phone, email, or in person.
This research aims to establish clinical evidence for optimal treatment guidelines for adrenal diseases using real-world data. The approach involves building prospective and retrospective patient registries, which will be utilized to develop and conduct research on disease-specific protocols for adrenal disorders. The study targets patients with primary aldosteronism, pheochromocytoma, adrenal cancer, adrenal incidentalomas, and mild autonomous cortisol secretion. Registries for patients with adrenal diseases will be obtained from Seoul National University Hospital and Asan Medical Center, along with securing a common data model. The ultimate goal is to conduct research to generate clinical evidence for adrenal diseases using these resources.
The purpose of this study is to continue the evaluation of long-term safety of osilodrostat in 7 Canadian patients who have already received osilodrostat treatment in a previous Global Recordati-sponsored roll-over study and who, based on investigators' judgement, will continue benefiting with its administration.
The goal of this multicenter, observational, analytic, randomized clinical trial is to analyze the laparoscopic and robot-assisted method in the surgical treatment of patients with adrenal diseases. The main question it aims to answer are: 1. to find the superiority of one the the surgical method mentioned above 2. to compare the quality of life in patients with adrenal mass before surgery and after laparoscopic or robotic-assisted adrenalectomy.
Cortisol is an essential for life hormone secreted in a pulsatile pattern on a diurnal rhythm. Given the complexity of cortisol secretion on a circadian rhythm with pulsations, current methods of cortisol measurement have limitations. Therefore, a non-invasive and ambulatory method would be useful to measure cortisol levels in real-time. The main aim of the study is to compare cortisol levels across biological fluids (sweat, saliva, interstitial fluid, and blood) in order to validate in the long term a continuous and non-invasive cortisol measurement device (currently under development).
The main hypothesis of the HEPACORT study is that upon diagnosis of endogenous Cushing's syndrome, significant liver fibrosis may be present, particularly in the most severe forms of Cushing's syndrome. the HEPACORT study is the first exploratory study to assess the severity of liver fibrosis in patients with Cushing's syndrome or suspected of presenting by Magnetic Resonance Elastography (MRE).
Cushing's Syndrome is a rare disease resulting from prolonged exposure to high levels of circulating cortisol. Clinical manifestations are variable but many patients present a metabolic syndrome (abdominal obesity, insulin resistance, dyslipidemia, hypertension). With regard to the liver, experimental data have shown that excess cortisol leads in an increase in lipogenesis and a reduction in the oxidation of fatty acids. This, in association with an accumulation of visceral adipose tissue and deregulation of adipokines, may contribute to the development of hepatic steatosis in animals. However, few data is available in humans with only one study of 50 patients with Cushing's syndrome estimating the prevalence of hepatic steatosis at 20%. NAFLD (Non-Alcoholic Fatty Liver Disease), is defined as the presence of hepatic steatosis in the absence of secondary causes of intrahepatic fat accumulation. It is a heterogeneous disease ranging from simple liver steatosis, whose prognosis is generally considered to be benign, to inflammation (NASH, Non-Alcoholic Steato-Hepatitis) which may progress to fibrosis, cirrhosis and an increased risk of hepatocellular carcinoma. The prognosis for NAFLD is mainly related to the severity of hepatic fibrosis. In Cushing's syndrome, normalization of cortisol production is the most effective strategy to improve co-morbidities associated with hypercortisolism. However, some of these complications, especially the metabolic co morbidities, could not be completely reversible and no data is available about resolution of hepatic steatosis.
