Hyperparathyroidism Clinical Trial
Official title:
A Prospective Cohort Study to Describe the Evolution of Persistent Hyperparathyroidism in Kidney Transplant Recipients
The purpose of this study is to see if Hyperparathyroidism (HPT) is common in people who receive a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems, or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this research study is to better understand the evolution of Hpt in people during the first 12 months after receiving a kidney transplant.
Subjects are enrolled in the study and a 12-month observational phase will begin. During the observational phase, subjects will attend a total of 8 visits at approximately 1, 2, 4, and 8 weeks after kidney transplantation and at 3, 6, 9, and 12 months after kidney transplantation. During these visits, subjects will have a review of medication history, blood tests, and a kidney function test. The blood will be used to test the level of certain components of you blood to see if your HPT has resolved, stabilized, or advanced. At selected visits throughout the study, you will have a urine sample collected and a health questionnaire that will ask about your health. Information regarding transplant kidney biopsy (if performed) also will be collected. ;
