Filter by:Pain is a major complaint in hemodialysis (HD) patients. Concentrations of parathyroid hormone (PTH) >250 pg/ml are associated with chronic pain. Visual Analogue Scale (VAS) score which is used to assess the pain severity is positively related to PTH levels. This study is aimed to assess the effects of multiple mega dosages vitamin D supplementations in HD patients with chronic pain. It's a single-center, parallel, double-blind randomized control trial that administrations of 576,000 IU once a week of vitamin D3 for 4 weeks or placebo are for 120 eligible subjects. VAS and laboratory tests including serum concentrations of 25(OH)D, calcium, phosphorus, PTH and C-reactive protein will be evaluated.
1. Study content: This is a multicentre, double-blind, randomised controlled study to determine the optimal dose and duration of treatment for the correction of vitamin D insufficiency or deficiency in patients with CKD5d; to investigate whether vitamin D supplementation delays the increase in PTH levels in this group of patients; and to investigate the effects on changes in CKD-MBD-related markers, cardiovascular complications, cognitive function in this group of patients. 2. Study procedure: Based on the inclusion and exclusion of the patients, the study was conducted in accordance with the following criteria 2. Study procedure: Eligible subjects were screened according to inclusion and exclusion criteria and randomly divided into three groups: high-dose vitamin D group, low-dose vitamin D group and control group. Baseline data were collected before the intervention and each group was given different doses of regular vitamin D2 softgels or placebo and followed up. 25(OH)D, PTH, blood Ca, and blood P levels were measured every month; bone metabolism markers, FGF23, and blood counts, liver function, kidney function, lipids, and blood glucose were measured every 3 months; the prevalence of vascular calcification, the incidence of cardiovascular events, and changes in cognitive function scale scores were assessed 6 months after the intervention.
This is a phase 3, multi-center, randomized, double-blind, placebo-controlled study in children with stage 3-4 chronic kidney disease (CKD), secondary hyperparathyroidism (SHPT) and vitamin D insufficiency.
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.
Parathyroid glands are in the neck and produce a substance called parathormone which maintains the calcium level in the blood. Sometimes one or more of the parathyroid glands become hyperactive and produce too much parathormone which causes increased calcium in the blood which can cause ill effects on multiple parts of the body. Hyperactive glands are identified by Tc-99m Sestamibi (MIBI) scan which helps the surgeons to remove them with minimal risk to the patient. But about 30% of the time MIBI scan does not localize the hyperactive gland. There is some evidence that a new agent called F-18 PSMA (prostate-specific membrane antigen) can localize hyperactive parathyroid. This study is being done to collect preliminary data to answer the question: Can imaging with the PET tracer, F-18 PSMA (Pylarify), prior to parathyroid surgery, provide better information to a surgeon than the standard of care imaging with MIBI scan? Patients who are scheduled for parathyroidectomy and are scheduled for imaging with MIBI scan prior to surgery will be asked to take part in this study. This is a single institutional study to collect preliminary data to help do a larger study. Participants will get MIBI scan first, and the same day will get an F-18 PSMA scan which involves an injection in the vein, waiting an hour, and imaging of the neck and chest area for 10 minutes. The findings of F-18 PSMA will not interfere with the participant's management. Patients who participate will not directly benefit by participating in this study. If the scanning method using F-18 PSMA shows better results than MIBI scan (standard of care) then the investigators will conduct a larger multi-institutional study. If the results prove that F-18 PSMA is better than the standard of care in the larger study, then patients with hyperactive parathyroid patients in the future will benefit.

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.
