Active clinical trials for "Hypoparathyroidism"

Very few data has been published on the epidemiology of hypoparathyroidism worldwide: none exists specifically for France. Hypoparathyroidism could led to complications. Here, the investigators plan to collect data about both epidemiology, medication and complication of hypoparathyroidism in France.

This is a prospective three year natural history study of adults with hypoparathyroidism. The goal is to monitor patients with hypoparathyroidism to define end-organ damage in the context of the disease. Funding Source- FDA OOPD

Long-term conventional treatment of chronic hypoparathyroidism does not fully restore calcium homeostasis leading to increased morbidity, emergency events and reduced subjective health status. To further investigate general morbidity, hypocalcemic events, subjective and daily life performance in patients with chronic hypoparathyroidism a standardized interview as well as blood sampling and examinations such as echocardiography and renal ultrasound are performed.

This is a prospective study aiming to establish near-infrared autofluorescence technology and PTH test strip as a standardized process for finding and identifying parathyroid glands in thyroid surgery.

This main aim of this study is to check the level of knowledge and assess attitudes and behaviors of both participants and physicians regarding the risks and safe use of NATPARA. The survey will be done via internet, telephone, or paper and participants will be able to choose the method that is preferred. No study medicines will be provided to patients in this study.

This study is open to adults with hypoparathyroidism who complete the SHP634-101 study (PARALLAX Study). The purpose of this study is to see if rhPTH(1-84) is safe and effective in adults with hypoparathyroidism who previously participated in the SHP634-101 study. All participants enrolled in this study will receive rhPTH(1-84) once-daily for 52 weeks via an injection. Patients who complete the SHP634-101 study will have the option to screen for this extension study.

This is a multi-center, placebo-controlled, randomized, double-blind, multiple-ascending dose study in patients with hypoparathyroidism. The total duration of study medication treatment will be 13 weeks and includes a Fixed-Dose Treatment period and a Dose Titration Treatment period. The Fixed-Dose Treatment period consists of multiple daily dosing at a fixed dose level. Once patients have completed the Fixed-Dose Treatment period, patients will enter the Dose Titration Treatment period where PCO371 (or placebo), oral calcium and oral active vitamin D can each be titrated according to the patient's albumin-corrected serum calcium level.

Hypoparathyroidism is a rare condition associated with a low level of parathyroid hormone (PTH) in the blood. Hypoparathyroidism can be genetic and show up in childhood, or it can occur later in life. If it occurs later, it is usually due to damage or removal of the parathyroid glands during neck surgery. PTH helps control the amount of calcium in blood, kidneys, and bones. Low levels of calcium in the blood can cause a person to feel sick. It can cause cramping or tingling in the hands, feet, or other parts of the body. A very low blood calcium can cause fainting or seizures. The standard treatment for hypoparathyroidism is a form of vitamin D (calcitriol) and calcium supplements. Keeping normal blood levels of calcium can be difficult. Sometimes there is too much calcium in the urine even if the calcium levels in the blood are low. High calcium in the kidneys and urine can cause problems such as calcium deposits in the kidney (nephrocalcinosis) or kidney stones. High levels of calcium in the kidney may keep the kidney from functioning normally. Treatment with PTH will replace the hormone you are missing. Your disease may be better controlled on PTH than on calcium and calcitriol. Researchers at the NIH have conducted prior studies to establish synthetic human parathyroid hormone 1-34 (HPTH) as a treatment for hypoparathyroidism. Other studies have shown that PTH may improve calcium levels in blood and urine. The primary purpose of this research study is to evaluate the effects of synthetic human parathyroid hormone 1-34 (HPTH) replacement therapy on bone in adults and teenagers with hypoparathyroidism. The study takes 5 (Omega) years to complete and requires 12 inpatient visits to the National Institutes of Health Clinical Center in Bethesda, MD. The first visit will help the study team decide whether you are eligible. This visit will last 2 to 3 days. After taking calcium and calcitriol for 1 - 7 months you will return to the NIH Clinical Center for the baseline visit. The baseline visit is the visit that you will start your PTH; you will also undergo a bone biopsy during the visit. The baseline visit may last 7 to 10 days. You will then take PTH twice a day for 5 years. You will be asked to return to the NIH clinical center every 6 months for 10 follow-up visits. During one of the follow-up visits, you will have a second bone biopsy taken from the other hip. That second biopsy will be done after 1 year, 2 years, or 4 years of taking PTH; the researchers will assign the timing of the second biopsy randomly. You will be asked to go to your local laboratory for blood and urine tests between each follow up visit. At first the blood tests will occur at least once a week. Later, you will need to go to your local laboratory for blood tests at least once a month and urine tests once every 3 months. The local laboratory visits and follow-up visits at the NIH Clinical Center will help the study team determine whether the HPTH treatment is controlling your hypoparathyroidism.

This study evaluated the effects of teriparatide (Forteo) on low calcium levels in the setting of thyroid surgery associated with low parathyroid hormone. The hypothesis was that teriparatide ( Forteo) would shorten the length of hospitalization post thyroidectomy in patients with symptomatic hypoparathyroidism.

The main aim of this study is to find out the long-term safety and effectiveness profile of recombinant human parathyroid hormone (1-84) (rhPTH[1-84]) treatment in participants with chronic hypoparathyroidism under conditions of routine clinical practice. Participants will be treated according to their clinic's standard practice determined by the treating doctors. Each participant will fill out a study questionnaire during a routine doctor visit.
