Active clinical trials for "Hypoparathyroidism"

Hypoparathyroidism is a rare condition in which the parathyroid glands fail to produce sufficient amount of parathyroid hormone or the parathyroid hormone produced lacks biologic activity. The most common cause of hypoparathyroidism is damage to or removal of the parathyroid glands due to neck surgery for another condition. Occurrence of hypercalciuria under treatment is a frequent concern in primary hypoparathyroidism, limiting correction of hypocalcemia. Hypoparathyroidism can also be caused by an autoimmune process. In rare cases, hypoparathyroidism may occur as a genetic disorder inherited as an autosomal recessive, autosomal dominant or X-linked recessive trait. The autosomal dominant hypocalcemia (ADH) is mainly caused by heterozygous activating mutations in the CASR gene encoding CaSR). As other severe presentation of primary hypothyroidism, ADH is characterized by the increased risk to develop hypercalciuria and nephrolithiasis. The purpose of the study is to compare two therapeutic approaches in severe hypoparathyroidism in order to limit the risk of nephrocalcinosis and renal failure when attempting to correct hypocalcemia: rhPTH(1-34) vs association of active vitamin D and hydrochlorothiazide. The European Society of Endocrinology Clinical has indeed recently published guidelines for the treatment of chronic hypoparathyroidism in adults. These guidelines suggest considering treatment with a thiazide diuretic In a patient with hypercalciuria and replacement therapy with PTH in patients who do not stably and safely maintain their serum and urinary calcium in the target range.

This study has been important in establishing synthetic human parathyroid hormone 1-34 (PTH) as a beneficial treatment for hypoparathyroidism, superior to conventional therapy with calcium and calcitriol. Providing synthetic human parathyroid hormone 1-34 (PTH) to patients who are unresponsive to conventional therapy has enabled severe cases of hypoparathyroidism to be managed effectively with the investigational drug, PTH. The primary goals of this study are to (1) provide long-term PTH therapy to patients who do not respond to conventional therapy; (2) understand the long-term effect of therapeutic PTH replacement on kidney function and bone mineral density; (3) study and track linear growth and bone accrual in children with hypoparathyroidism. (4) determine if subjects reach a normal level of peak bone mass and if the timing of this is comparable to normal age-matched healthy controls.

Prospective, observational, single-center study about the use of indocyanine green angiography during total thyroidectomy. The main objective of the study is to identify a quantitative score of parathyroid vascularization as an outcome of angiography that correlates with the absence of postoperative hypoparathyroidism. It is planned to enroll 66 patients.

Study hypothesis: supplementary magnesium may influence the blood calcium level in treated hypoparathyroid patients. Patients will be treated with supplementary magnesium (350 mg/day) for 3 weeks. Calcium and other relevant blood parameters will be measured before the treatment, at the end of treatment and 2 weeks after stopping treatment.

The purpose of the investigation is to study if the use of Fluobeam®-LX to identify parathyroid glands through autofluorescence during thyroid surgery, may reduce the risk of postoperative hypoparathyroidism, defined as low PTH in patients undergoing total thyroidectomy

This clinical study aims to evaluate the safety and efficacy of repeated dosing of recombinant human parathyroid hormone (rhPTH[1-84]) in Japanese participants with chronic hypoparathyroidism for a 26-week period.

Hypoparathyroidism (hypoPT) is characterized by low levels of PTH. In this study we will test the effects of a liquid meal on the bone remodeling in participants with hypoparathyroidism. Furthermore, we will test the effects of the gut hormones GIP and GLP-2.

This is an open-label study of PTH(1-84) treatment that seeks: To determine the actions of PTH(1-84) to provide long term control of serum calcium and urinary calcium excretion with use of standard amounts of calcium and vitamin D supplementation. To determine the extent to which PTH(1-84) improves quality-of-life on long-term basis. To establish the safety of PTH(1-84) when administered for up to 12 years. To attempt to quantify improvements in the typical signs/symptoms of hypoparathyroidism post PTH administration. There will be one visit conducted every six months in the study offices of the principal investigator, Dr. John Bilezikian. In addition to these visits, there will be, for new patients who have not used PTH (1-84) before, a Screening Visit four weeks prior to the baseline visit for the purpose of performing screening labs as well as a Pre-Baseline Local Quest Lab performed to ensure stability prior to Baseline.

The incidence of thyroid cancer (TC) has increased exponentially worldwide. The increase in diagnosed cases brings about an increase in the number of surgeries performed on the thyroid gland, especially total thyroidectomy (TT), given that at present is still the gold standard of treatment. Transient postoperative hypoparathyroidism (HPT) is one of the most frequent complications, with an incidence of between 10 and 46% according to different sources. HPT involves longer hospital stay, serial measurements of blood glucose, treatment with calcium and vitamin D (with potential risk of hypercalcemia) and therefore an increase in terms of the costs of the health system. While the investigators know the analgesic, anti-inflammatory, immunomodulatory and anti emetic of corticosteroids in thyroid surgery, the literature available to date is discordant in the use of steroid and its interaction with the HPT making clear the need for randomized clinical trials specific to analyze these variables more accurately. As inflammation and edema constitute a proposed surgical manipulation in the pathogenesis of HPT component, investigators decided t conduct a prospective randomized, triple-blind, in order to assess the potential benefits of the most common postoperative complication reported in TT. Our primary objective is to evaluate the safety and efficacy of single-dose corticosteroids deposit immediately postintubation in preventing the development of transient hypoparathyroidism (PTH, serum calcium and symptoms) in patients after TT.
