Active clinical trials for "Endocrine System Diseases"

Increasing evidences suggest that infections are important etiological factors for the development of Type 1 Diabetes (T1D). The overall hypothesis of the study is that the treatment of children, during the first year after diagnosis of T1D with Azithromycin, combined with repeated episodes of intensified insulin treatment to induce maximal beta-cell rest, and dietician support to promote dietary habits that minimize the likelihood of bacterial reflux from the duodenum to the pancreatic duct, will lead to preservation of beta cell function. This trial will examine whether the AIDIT protocol initiated within one week from diagnosis could preserve insulin production in children with Type 1 Diabetes.

This study will examine the impact of manual physical therapy on endocrine function in women diagnosed as being infertile due to elevated follicle stimulating hormone (FSH) levels (10 mIU/mL or higher) on days 2-5 of their menstrual cycle. It is hypothesized that the manual physical therapy will decrease FSH levels.

The aim of this study is to evaluate the effects of subantimicrobial dose doxycycline (50 mg/d), administered for 12 weeks, on patients with mild Thyroid-Associated Ophthalmopathy (TAO).

The purpose of the study is to evaluate the safety and effectiveness of ALTU-238 in the treatment of children with growth hormone deficiency who have not yet reached puberty who lack the normal ability to make growth hormone themselves. This study will also test if ALTU-238 works as a weekly treatment.

The purpose of this study is to test how soluble epoxide hydrolase (sEH) inhibition with GSK2256294 affects tissue sEH activity and insulin sensitivity.

Endocrine disorders like Type 2 diabetes mellitus (T2DM) represent complex cardiometabolic disease processes affecting approximately 462 million individuals worldwide and is associated with a two- to three-fold increase in cardiovascular mortality. Individuals with T2DM are at an increased risk of developing cardiovascular disease. Research has shown individuals with T2DM and no previous history of coronary artery disease are still at similar risk rates for cardiovascular events as patients with a prior myocardial infarction. The MAgenetoCardiography ENDOcrine Registry (MACENDOR) study is designed to collect CardioFlux scans on a select group of volunteers who are high-risk patients with endocrine disorders. CardioFlux is used as a noninvasive magnetocardiography (MCG) tool that analyzes and records the magnetic fields of the heart to screen volunteers for heart disease. There will be a 12-month duration of the study where we propose to collect screening data from approximately 250 volunteers who present to the Genetesis facility for a 5-minute CardioFlux scan. The volunteers will be contacted at intervals over a 1-year period for follow-up data and may choose whether or not they would like to provide follow-up data or participate in another scan.

The aim of the study is to determine the specificity and sensitivity of the combined growth hormone releasing hormone (GHRH) + Arginine test in healthy volunteers, subjects with highly probable adult growth hormone deficiency (AGHD) and subjects who were probably free of AGHD.

Cushing Syndrome is an endocrine disorder causing an over production of the hormone cortisol. Cortisol is produced in the adrenal gland as a response to the production of corticotropin (ACTH) in the pituitary gland. Between 10% and 20% of patients with hypercortisolism (Cushing Syndrome) have ectopic production of the hormone ACTH. Meaning, the hormone is not being released from the normal site, the pituitary gland. In many cases the ectopic ACTH is being produced by a tumor of the lung, thymus, or pancreas. However, in approximately 50% of these patients the source of the ACTH cannot be found even with the use of extensive imaging studies such as computed tomography (CT) scans, magnetic resonance imaging (MRI), and nuclear scans (111-indium pentetreotide). The ability of these tests to locate the source of the hormone production is dependent on the changes of anatomy and / or the dose and adequate uptake of the radioactive agent. The inability to detect the source of ectopic ACTH production often results in unnecessary pituitary surgery or irradiation. Unlike the previously described tests, positron emission tomography (PET scan) has the ability to detect pathologic tissue based on physiologic and biochemical processes within the abnormal tissue. This study will test whether fluorine-18-fluorodeoxyglucose (FDG), fluorine-18-dihydroxyphenylalanine (F-DOPA) or use of a higher dose of 111-indium pentetreotide can be used to successfully localize the source of ectopic ACTH production.

Polar stays expose people to extreme climate, isolation and confinement. The combination of these factors induces psychological disorders, sleep disorders, immune and endocrine disturbances, and deficiencies. In the TAAF, (French Southern and Antarctic Lands) two types of population coexist: winter residents, exposed to these stressors over long periods, and country people, who benefit from milder conditions and only make short stays. In this context, the investigators have decided to set up this cohort study with the objective of comparing the state of health of the winterers of the TAAF from 2012 to 2017 with that of the country people of the same period, before their stay, during and the year following their return.

This is a dose escalation study to determine the maximum tolerable dose of Parathyroid Hormone-related Protein, PTHrP, or Parathyroid Hormone, PTH, that can be given safely over one week in healthy African-American volunteers. The investigators plan to infuse low doses of intravenous PTHrP or PTH to determine if it leads to a sustained and progressive suppression of bone formation as occurs in humoral hypercalcemia of malignancy (HHM) or an increase in bone formation as occurs in hyperparathyroidism (HPT). Additionally, the investigators will assess the direct influence of PTHrP and PTH on vitamin D metabolism, markers of bone turnover, and fractional excretion of calcium. These results will be compared to previous studies of Caucasian volunteers.
