Filter by:The study aims to test if autofluorescence imaging (AF) is a useful surgical aid during parathyroidectomy (PTX) for primary hyperthyroidism (PHPT).
The purpose of this study is to assess glycemic control after parathyroidectomy in patients with primary hyperparathyroidism and concomitant type 2 diabetes mellitus.
CoHPT is a prospective, monocentric, observational cohort including all patients diagnosed with primary hyperparathyroidism in Nantes University Hospital, aiming to study the outcomes associated with parathyroidectomy. Clinical and biochemical evaluation is performed at the inclusion, and 6, 12, 36 and 60 months. A biocollection is collected. The main hypotheses are that parathyroidectomy could improve cardiovascular, renal, bone, and cardiovascular outcomes along with quality of life.
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.
This study will see if 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 is better than a surgeon's detection alone. It compares risk-benefits and outcomes in PTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.
Background: Parathyroid disorders are very common in the general population and include disorders of parathyroid excess, deficiency, or defects in parathyroid hormone (PTH) signaling. PTH, the main secretory product of parathyroid glands is responsible for regulation of calcium-phosphate homeostasis. Objective: i) To investigate the cause of parathyroid disorders ii) To describe evolution, natural history, and longitudinal trends of parathyroid and related disorders seen in syndromic presentations like multiple endocrine neoplasia, hyperparathyroidism-jaw tumor syndrome Eligibility: People ages 6 months older who have, are at risk of having, or are related to a person with a parathyroid or related disorder. Design: Participants will be screened with a review of their medical records. Participants will be seen, tested, and treated by doctors based on their condition. Their visits may be in person or via telehealth. Participants will complete questionnaires. They will answer questions about their physical, mental, and social health. Participants may give samples such as saliva, blood, urine, or stool. Participants may give cheek cell samples. They will do this using a cheek swab or by spitting into a cup. Adult participants may give a skin biopsy. For this, a small bit of skin is removed with a punch tool. Participants may have medical photos taken. If participants have surgery during the course of their regular care either at the NIH or at a different hospital or doctor s office, researchers will ask for some of the leftover tissue. Participants will be in the study as long as they are being seen by their doctor.
Primary hyperparathyroidism (PHPT) may induce bone loss according with the composition of the gut microbiota (GM), and particularly, on the presence of intestinal bacterial that induce T helper 17 differentiation. We will evaluate GM composition and evaluate how GM modulates immune system in patients affected by PHPT with or without skeletal involvement. Furthermore, we will unravel the causal relationship between GM composition and T cells activation. Upon success, HYPOGEUM will show that GM sequencing is a screening tool to identify PHPT that will lose bone, suggesting novel strategies with antimicrobial treatments to prevent bone loss. HYPOGEUM will yield essential data to understand and prevent skeletal complications associated with PHPT.
This is a prospective single arm single center Phase III study evaluating the ability of 18F-fluorocholine to detect the location of parathyroid adenomas.
Primary hyperparathyroidism (PHPT) is a disorder of one or more of the parathyroid glands. The parathyroid gland(s) becomes overactive and secretes excess amounts of parathyroid hormone (PTH). As a result, the blood calcium rises to a level that is higher than normal. PHPT is associated with several other metabolic complications as osteoporosis, kidney stones, hypertension, insulin resistance, cardiac calcifications, cardiac arrhythmias, and kidney failure. Renal function deterioration over time has also been reported. However, the role of parathyroidectomy on renal function remains controversial in patients with PHPT. In some studies, surgical cure of PHPT has been shown to halt renal function deterioration in patients with coexisting renal disease. On the other hand, other studies showed no significant impact of parathyroidectomy on renal function. Consequently, the goal of this study was to evaluate renal function before and after parathyroidectomy in a large cohort of patients with pHPT.
Patients with biochemically confirmed primary hyperparathyroidism and non-localizing SPECT-CT exam within the past year will be included. Subjects will be treated with calcitonin to lower calcium levels immediately prior to reimaging. The goal of this study is to determine whether lowering calcium will improve uptake/retention of sestamibi and improve sensitivity of SPECT-CT to localize parathyroid adenoma.
