NCT ID: NCT03027349 Completed - Hyperparathyroidism Clinical Trials

Serum Calcium to Phosphorous Ratio (Ca/P) as a Simple, Inexpensive Screening Tool in the Diagnosis of Primary Hyperparathyroidism

Start date: January 2011
Phase: N/A
Study type: Observational

Background: Primary hyperparathyroidism (PHPT) is often overlooked and underdiagnosed. At present the diagnosis of PHPT remains challenging and is based on serum calcium (Ca) and PTH. As serum Ca and phosphorous (P) are inversely related in PHPT, the Ca/P ratio might be considered a good candidate tool in the diagnosis of PHPT. AIM: The aim of this study is to investigate the diagnostic value of the Ca/P ratio in the diagnosis of PHPT. Study design: Retrospective, observational, cross-sectional, case-control clinical trial will be carried out. Biochemical measurements will include PTH, Vitamin D, serum Ca, P, albumin, and creatinine.

NCT ID: NCT03011736 Completed - Clinical trials for Primary Hyperparathyroidism

Omission of Intact Parathyroid Hormone Testing During Surgery in Treating Patients With Primary Hyperparathyroidism

Start date: May 12, 2016
Phase: N/A
Study type: Interventional

This clinical trial studies the omission of intact parathyroid hormone testing during surgery in treating patients with primary hyperparathyroidism. Omission of intact parathyroid hormone testing during parathyroid gland removal may help patients with primary hyperparathyroidism to decrease their time under anesthesia, and decrease the overall time and cost of surgery.

NCT ID: NCT02989428 Completed - Clinical trials for Primary Hyperparathyroidism

Effect of Parathyroidectomy on Cardiovascular Health

Start date: February 3, 2017
Phase: N/A
Study type: Interventional

The aim of this study is to establish whether patients with mild primary hyperparathyroidism (PHPT) have an increased risk of cardiovascular diseases. The primary outcome is to determine whether arterial stiffness and blood pressure will decrease in patients with mild PHPT 3-month after parathyroidectomy (PTX).

NCT ID: NCT02895061 Completed - Clinical trials for Alfacalcidol, Secondary Hyperparathyroidism, Hemodialysis

Effectiveness of Oral Alfacalcidol for Secondary Hyperparathyroidism in Chronic Hemodialysis Patients.

Start date: January 2015
Phase: N/A
Study type: Interventional

Primary objective was to evaluate the efficacy between daily and pulse oral alfacalcidol treatment of SHPT in chronic hemodialysis patients, a 12-week treatment. Secondary objective was to observe the adverse effects between these two treatment regimens.

NCT ID: NCT02833857 Completed - Clinical trials for Chronic Kidney Disease, Secondary Hyperparathyroidism

A Single-dose Study in Paediatric Patients Aged 2 to Less Than 18 Years With Secondary Hyperparathyroidism (sHPT) Receiving Haemodialysis

Start date: March 14, 2017
Phase: Phase 1
Study type: Interventional

This is a study to evaluate the safety and pharmacokinetics in pediatric patients with secondary hyperparathyroidism receiving a single dose of etelcalcetide at the end of hemodialysis.

NCT ID: NCT02830789 Completed - Clinical trials for Hyperparathyroidism, Secondary

Investigation of the Optimal Calcium Supplement Following Roux-en-Y Gastric Bypass

Start date: December 2016
Phase: N/A
Study type: Interventional

This study investigates whether calcium citrate or calcium carbonate are the optimal supplement to treat secondary hyperparathyroidism following Roux-en-Y gastric bypass operation. Half of the participants will be randomized to receive calcium citrate, while the other half will receive calcium carbonate. The study will be double blinded.

NCT ID: NCT02747979 Completed - Insomnia Clinical Trials

The Effect and Safety of Hemodialysis and Hemoperfusion on Severe Renal Osteopathy and Itching in Uremia Patients

Start date: April 2009
Phase: Phase 2/Phase 3
Study type: Interventional

A prospective, randomized, controlled open clinic trial to evaluate the effect and safety of combination of conventional hemodialysis(HD) and hemoperfusion(HP) on middle molecules removal and complications improvement in long-term maintenance hemodialysis (MHD) patients. There are two phases of study for each subject. Phase 1 (screening phase). During this phase, each potential subject will be evaluated to determine if he/she is eligible for the study. Phase 2 (intervention phase). Each subject will be randomly allocated to HD+HP(HA130 once per week) group ,HD+HP(HA330 once per week) group and HD group. The follow-up duration was 3 months.

NCT ID: NCT02591160 Completed - Hyperparathyroidism Clinical Trials

Optimal HCTZ Cessation for Diagnosis of Hyperparathyroidism

Start date: May 2015
Phase: N/A
Study type: Interventional

Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcemia in the ambulatory setting. PHPT may be cured with surgery and indications for intervention have been defined and include urinary calcium/creatinine clearance. Hydrochlorothiazide (HCTZ), the most commonly prescribed medication for hypertension, reduces urinary calcium excretion and confounds urinary testing. As a result, it is universally recommended that thiazide diuretics be stopped in advance of urinary testing. To date, no studies are available to provide evidence-based guidance as to how long HCTZ must be held for urinary calcium excretion to return to steady state in PHPT. The objective of this study is to serially calculate urinary calcium/creatinine clearance ration in patients with suspected PHPT while holding HCTZ to determine the minimum duration of medication cessation necessary for urinary calcium clearance to reach steady state.

NCT ID: NCT02549417 Completed - Clinical trials for Secondary Hyperparathyroidism

Phase 3 Study of KHK7580

Start date: September 29, 2015
Phase: Phase 3
Study type: Interventional

This study is designed to evaluate efficacy and safety of KHK7580 orally administered once daily for 32 weeks for patients with secondary hyperparathyroidism receiving peritoneal dialysis. After 32-week treatment period, the subjects will receive KHK7580 in the 20-week extension period to evaluate long-term safety and efficacy.

NCT ID: NCT02549404 Completed - Clinical trials for Secondary Hyperparathyroidism

Phase 3 Study of KHK7580

Start date: September 28, 2015
Phase: Phase 3
Study type: Interventional

This long-term study is designed to evaluate safety and efficacy of KHK7580 orally administered once daily for 52 weeks for patients with secondary hyperparathyroidism receiving hemodialysis.
