HyperparathyroidismNCT01163669
A Prospective Cohort Study to Describe the Evolution of Persistent Hyperparathyroidism in Kidney Transplant Recipients
An observational study of Hyperparathyroidism, run by The Cleveland Clinic at 1 site in United States.
Trial summary
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).

About this study
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.
Read the detailed description
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
plasma parathyroid hormone(PTH)level (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2013.
