Filter by:This was a multiple-dose, double-blind, randomized, placebo-controlled study. Chinese subjects residing in Mainland China with chronic kidney disease (CKD) receiving hemodialysis were randomized in a 3:1 ratio to receive 5 mg intravenous (IV) of etelcalcetide or placebo 3 times a week (TIW) for approximately 4 weeks, with a subsequent follow up period of approximately 4 weeks. Doses were given at the end of each scheduled hemodialysis session on study days 1 through day 27 and subject participation was complete after day 55 end-of-study (EOS) procedures were performed. Doses were administered TIW for 4 weeks, for a total of 12 doses.
To evaluate the efficacy of KHK7580 orally administered up to 24 weeks for hypercalcemia in patient with parathyroid carcinoma or primary hyperparathyroidism who are unable to undergo parathyroidectomy or relapse after parathyroidectomy.
This study is conducted to assess the efficacy and safety of SK-1403 in Hemodialysis Patients with Secondary Hyperparathyroidism. In the first treatment period, the efficacy of SK-1403 is assessed after 18 weeks of treatment with SK-1403 individually dose-adjusted . Safety is also assessed during this period. Patients who completed the first treatment period proceed to the second treatment period and receive the treatment with SK-1403 for 34 weeks. Efficacy and safety of SK-1403 are also assessed during this period.
To assess the efficiency of 18F-fluorocholine PET/CT in localization of hyperfunctioning parathyroid tissue in hyperparathyroidism, thereby enabling minimally invasive surgical approaches with fewer complications and comparable success rates
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.
Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated. The investigators will perform a comparative trial testing etelcalcetide vs. alfacalcidol treatment on top of conventional HPT therapy for 12 months. A total of 62 hemodialysis patients with sHPT and LVH will be enrolled in the study. After a washout of all calcimimetic and vitamin D treatment, subjects will be randomized at 1:1 ratio to either etelcalcetide or alfacalcidol. The participants will undergo cardiac imaging consisting of cardiac resonance imaging (cMRI) and strain echocardiography before and at baseline and one year. Etelcalcetide or alfacalcidol will be administered intravenously three times per week following chronic hemodialysis treatment. The primary end point will be a change in left ventricular mass index (LVMI) measured in g/m2. As secondary end points the changes in left atrial diameter (LAD), cardiac fibrosis, wall motion abnormalities and left ventricular function, changes in serum FGF 23 and soluble Klotho levels as well as changes in proBNP as well as pre- and postdialysis troponin T (TnT) levels will be determined. Additionally a quantitative analysis of the treatment influence on the individual metabolites of the renin-angiotensin-aldosterone system (RAAS) will be performed using mass spectrometry ("RAAS fingerprint").
The aim of this study is to evaluate the prevalence of secondary hyperparathyroidism among patients with diabetic nephropathy.
1. To evaluate achievement ratio of iPTH,Calcium and phosphorus after taking Cinacalcet HCL in hemodialysis subjects with mild, moderate and severe SHPT; 2. To explore the impact of Cinacalcet HCL using on the combined use of drugs; 3. To explore the difference of patients who continued or discontinued Cinacalcet HCL in real-world period from 33rd to 52nd week.
Protocol title: Alterations in functional characteristics of the muscle tissue following surgery for primary hyperparathyroidism. Purpose: To detect any changes in functional characteristics of muscles in patients who undergo surgery for primary hyperparathyroidism compared to patients with primary hyperparathyroidism and conservative treatment, patients undergoing thyroid surgery and healthy subjects. Design: Prospective, multi-center observational study Patient Population: Male or female subjects 18 years of age or older scheduled for parathyroidectomy No. of Subjects: 50 patients undergoing parathyroidectomy, 50 patients undergoing conservative follow up, 50 patients undergoing thyroid surgery due to nontoxic multinodular goiter or solitary nontoxic thyroid adenoma and 50 healthy control subjects, estimated up to 12 months to enroll. Duration of Treatment: During the operation Duration of Follow-up: Follow-up will be performed daily during hospitalization and at 3, 6 and 12 months after the procedure Endpoints: To evaluate the changes in functional characteristics of all the type of muscles which occur after parathyroidectomy for primary hyperparathyroidism.
Chronic kidney disease (CKD) patients often have associated systemic hypertension due to volume retention, as one of the mechanisms, therefore the use of diuretics is widespread in this population. One of the major complications of CKD is mineral and bone metabolism disorder (CKD-MBD), which include changes in the levels of calcium, phosphorus, vitamin D deficiency, increased circulating levels of fibroblast growth factor (FGF-23) and parathyroid hormone (PTH). These alterations are responsible for fractures, cardiovascular disease and mortality among patients with CKD. According to diuretic mechanism of action, sometimes increasing serum calcium (in the case of furosemide), sometimes decreasing it (in the case of thiazide), it is expected that the serum calcium may be altered, even within the range of normality, with consequent impact on the levels of PTH. Although most studies have shown that the use of thiazide diuretics decreases the risk of fractures, some showed the opposite. Similarly, although most studies have shown increased risk of fracture in association to loop diuretics use, some have failed in demonstrated this outcome. Only one study, a cohort study in a population of CKD, showed that furosemide was directly related to increased calciuria and PTH levels and the use of thiazide, in turn, showed completely opposite effect. However, certain issues are still not completely solved, for example, the interference of renal function itself on calciuria. It is possible that calciuria is not a so simple explanation that justifies the PTH levels changes, as no correlation was seen between calciuria and PTH levels. Better understanding of the exact relationship between the use of diuretics and the impact on CKD-MBD may be an alternative intervention, easily accessible and relatively inexpensive. The purpose of this study is to evaluate the impact of diuretic, specifically hydrochlorothiazide and furosemide, on bone architecture and mineral metabolism.
