Filter by:During surgery, a fine needle puncture was proceeded when suspicious nodes was found by clinician. Repeat the punction for 2-3 times from different orientation and then, Diff-quik staining or PTH immunochromatographic assay were proceeded for lymph node or parathyroid glands identification. Post-operative pathology outcome was considered as golden standard.
This study aims to compare two different protocols commonly used in the management of post thyroidectomy hypoparathyroidism : PTH based calcium repletion and empiric repletion. The investigators aim to compare the quality of life associated with these two protocols in a randomized trial.
Results from KDOQI guidelines, parathyroid hormone (PTH) level within target range is 150-300pg/ml. Both lower PTH levels and higher PTH levels were associated with higher risk of all-cause mortality. However, in out of target range, it is still unknown which mortality higher. so, in this prospective, observational clinical trial study. the investigators will observe the mortality and cardiovascular incidence rate between SHPT(>800pg/ml) and low serum PTH levels(<60pg/ml). Both two groups of patients will receive a reasonable treatment according to the suggestions in K/DOQI guidelines.
The purpose of this study is to compare how rhPTH(1-84) affects the body between healthy adults of Japanese descent and matched, healthy Caucasian adults.
The investigators hypothesise that parathyroid hormon (PTH) depletion interferes with normal activity of the hypothalamus-pituitary-adrenal (HPA)-axis and the renin-angiotensin-aldosterone-system (RAAS), which in turn may impact morbidity and quality of life. The main objective of the current study is to test if PTH deficiency influences the secretion of corticosteroids and whether any abnormalities in the HPA-axis and the RAAS-system can be reversed by PTH infusion.
The main objective of this study is to establish an optimal threshold Early parathormon (PTH) assay in order to exclude hypoparathyroidism , that is to say to obtain a negative predictive value of hypoparathyroidism highest possible.
Chronic hypoparathyroidism is a life-long and irreversible disease for which the chronic administration of rhPTH(1-84) is a potential treatment option. The group of participants in the AAAE0544 core study has been taking rhPTH(1-84) for the treatment of hypoparathyroidism for up to 11 years. This study is designed to extend this experience and gain knowledge about how safe and effective rhPTH(1-84) is in participants with hypoparathyroidism over a long-term duration.
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.
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 is being conducted to characterize the effects of twice daily administration of rhPTH(1-84) on the way the body handles rhPTH(1-84) as well as its actions and safety and tolerability over the course of 24 hours as compared with the current once daily dosing regimen of marketed rhPTH(1-84) (marketed in the United States as Natpara® and in the EU as Natpar).
