Active clinical trials for "Hyperparathyroidism"

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.

This study will evaluate how Quadriceps Femoris muscle fatigue protocol affect the spatio-temporal gait parameters, gait symmetry and balance in individuals with primary hyperparathyroidism before and after parathyroidectomy. Study group will consist of 20 subjects with primary hyperparathyroidism (PHPT) and control group will consist of 20 healthy subjects.

Treatment of renal osteodystrophy is impeded by the lack of practical and accurate tools to determine underlying bone turnover. Gold standard bone biopsy is not practical in the clinic for the vast majority of kidney disease patients and parathyroid hormone and bone alkaline phosphatase have insufficient accuracy for turnover type to safely and confidently guide treatment of renal osteodystrophy. In the present investigation, the investigators will study a microRNA approach as a novel non-invasive biomarker of turnover for renal osteodystrophy.

Primary Objective: Evaluate the effect of Hectorol® capsules in reducing elevated levels of intact parathyroid hormone (iPTH). Secondary Objectives: Evaluate the safety profile of Hectorol® capsules versus Rocaltrol® (calcitriol) capsules. Determine the pharmacokinetic profile of 1,25-dihydroxyvitamin D2 after administration of Hectorol®.

Safety, Efficacy, PK and PD of CTAP101 (calcifediol) ER Capsules for SHPT in HD Patients VDI

The study is being conducted to evaluate the efficacy and safety of SHR6508 for Chinese patients with secondary hyperparathyroidism of chronic kidney disease treated by maintenance hemodialysis.

This is a prospective single arm single center Phase III study evaluating the ability of 18F-fluorocholine to detect the location of parathyroid adenomas.

General consensus and contemporary guidelines, recommend surgery for primary hyperparathyroidism (pHPT)for all patients below the age of 50, for patients with pronounced hypercalcemia and for patients with organ complications to the disease (osteoporosis and decreased renal function). The purpose of this study is to determine if surgery for pHPT, is appropriate for patients with moderate to mild hypercalcemia older than 65 years of age. The hypothesis of the study is that surgery for pHPT in patients older than 65 years of age, and with mild hypercalcemia, will increase bone density and hence decrease future risk for fragility fractures compared to patients with follow-up only.

Kidney stones are very common. They affect 3-5% of the population in the United States. Many people are hospitalized for the treatment of kidney stones and some may die. Better understanding of what causes kidney stones is useful in both the treatment and prevention of kidney stones. However, exactly what causes kidney stones is unknown. The most common type of kidney stones contains calcium, which sometimes is attached to a part of the kidney important in producing the final urine, called the papilla. The investigators have noticed that persons who form kidney stones seem to have more papilla with stones attached. They propose to study these areas of the papilla, called Randall's plaques (named after their discoverer), in patients undergoing surgery for kidney stones.

The goal of this study is to assess whether using PTeye (AiBiomed, Santa Barbara, CA) - a NIRAF detection modality - can improve patient outcomes and reduce healthcare associated costs after parathyroid surgeries. By being able to quickly and definitively locate parathyroid glands while in the operating room, the duration of surgical procedure could be further reduced. In addition, the number of frozen section biopsy and associated costs can be minimized. Furthermore, repeat surgeries as a result of missing a diseased parathyroid gland at the time of the initial parathyroidectomy for hyperparathyroidism could potentially be avoided.
