View clinical trials related to Hyperparathyroidism.
Filter by:Hyperparathyroidism is a common endocrine disorder which can result in many severe complications. For patients with hyperparathyroidism, Tc-99m sestamibi imaging is the major imaging tool for pre-operative localization of the hyperfunctioning gland. However, sestamibi scan have only limited sensitivity in detecting multigland disease and hyperplastic foci. New imaging tracer with 18F-fluorocholine (18F-FCH) has showed avidity in parathyroid tissues. Nevertheless, the research data of 18F-FCH PET/CT are only preliminary. The goal of our study is to compare the diagnostic performance of 18F-FCH PET/CT and single isotope dual phase sestamibi scintigraphy for patients with hyperparathyroidism. From Jan. 1st, 2018 till Dec. 31st, 2019, the investigators will prospectively enroll patients with biochemical evidence of hyperparathyroidism and intended to receive pre-operative image study. The patients will receive single isotope dual phase sestamibi scintigraphy and 18F-FCH PET/CT. Each image will be evaluated by experienced interpreter for abnormal uptake suspicious for hyperfunctioning parathyroid gland. The reference standard will be the final surgical results. Diagnostic performance of both sestamibi scan and PET/CT scan will be measured and calculated.
The purpose of this project is to examine, in a non-inferiority study, whether the combination of conventional ultrasound and contrast-enhanced ultrasound (CEUS) can replace the radiation-based imaging modalities that are currently used to localize pathological parathyroid glands prior to surgical removal in patients with primary hyperparathyroidism. This will take the form of a prospective paired cohort study where included patients receive a contrast-enhanced ultrasound examination in addition to the standard preoperative imaging regimen (subtraction scintigraphy with SPECT/CT and conventional ultrasound). Patients act as their own controls as all included patients undergo both CEUS and conventional imaging.
This study describes a single center, randomized, single-blinded clinical trial to assess the clinical benefits of the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during parathyroidectomy (PTx) procedures. It compares risk-benefits and outcomes in PTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.
In this study, investigators measure patient's voice frequency, swallowing function, and O2 desaturation of the 6 mins walking test before surgery and 4 months after surgery, to find the increase of voice frequency, and swallowing function and the decrease of O2 desaturation.
Currently, the indications used for MA (Marketing Authorization) Cinacalcet in France are hyperparathyroidism (hyperPTH) in adults, whether primary (for patients in whom parathyroidectomy is theoretically indicated but in whom it is contraindicated or not is not clinically appropriate) or secondary to a chronic kidney disease, and parathyroid carcinomas. In pediatric patients, data on its use are restricted due to its recent marketing authorization (2017) and limited to dialysis patients suffering from secondary hyperPTH. Nevertheless, some patients with phosphocalcic pathologies without renal insufficiency must be treated off-label by cinacalcet in the presence of severe hyperPTH, without any other chronic treatment available to date. The objective of this study is therefore to evaluate the use in France of cinacalcet in phosphocalcic pathologies without renal insufficiency, in order to obtain efficacy and safety data in order to improve our knowledge on the management of these orphan diseases.
Investigators will prospectively include 40 postmenopausal women with secondary osteoporosis due to primary hyperparathyroidism who have refused surgery. Participants will be randomized in two groups and treated either with zoledronic acid 5 mg iv once a year or with denosumab 60 mg sc every 6 months. Investigators will compare the effect of both drugs on bone turnover markers and basic laboratory parameters after 3, 12 and 24 months of treatment, and on the bone mineral density after 12 and 24 months of treatment. All participants will take cholecalciferol 800 - 1000 IU daily.
The main objective of this study is to evaluate the safety, efficacy and pharmacokinetics of paricalcitol oral solution in pediatric participants of ages 0 to 9 years with SHPT associated with stage 5 CKD receiving Peritoneal Dialysis (PD) or Hemodialysis (HD). The 24-week study is divided into two 12-week dosing periods (Dosing Period 1 followed by Dosing Period 2).
To compare efficacy and safety between bilateral superficial cervical plexus block combined with intravenous sedation (RA group) and general anesthesia (GA group) for thyroid and parathyroid operations. This study evaluates postoperative numerical pain score and systemic opioid requirement within 24 hours.
The investigators hypothesize that positron emission tomography with fluorocholline (F18-choline PET) will reduce the proportion of unnecessary invasive surgery decisions and that the higher cost of positron emission tomography versus MIBI scintigraphy (Tc99m-sestaMIBI ) will be offset by lower cost in terms of type. surgery performed wisely and complications.
A prospective database of consecutive patients with hyperparathyroidism subject to surgery is created. Preoperative workup and operative findings are recorded in this registry to allow comprehensive analysis.
