Tertiary hyperparathyroidism

This study compares parathyroid surgery to standard monitoring in 85 kidney transplant recipients who still have high calcium and parathyroid hormone levels. The goal is to see if surgery improves bone density, physical function, and quality of life over 12 months. Participants a…

This study at the National Institutes of Health is looking at 1,000 adults with known or suspected hormone gland (endocrine) disorders. The goal is to better understand these conditions and help train doctors. Participants may receive tests, treatments, or surgery as part of thei…

This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to be…

This study enrolls adults with known or suspected endocrine (hormone gland) disorders, such as diabetes or thyroid disease, to help researchers learn more about these conditions. Participants will undergo medical exams, blood and imaging tests, and possibly genetic testing. The m…

This phase 2 study is collecting tumor samples from 839 people with hyperparathyroidism who are having parathyroid surgery. Researchers want to see if the genetic makeup of the tumors (whether they are monoclonal or polyclonal) relates to how many glands are affected and how well…

This study is testing a tool called B-COMPASS that uses a 22-question survey to predict whether people will follow their prescribed treatments. Researchers will enroll 3100 adults with cardiovascular, endocrine, immune, nerve, cancer, or rare diseases across Europe. The goal is t…
