Optimal Anemia Treatment in End Stage Renal Disease (ERSD)

Anemia is one of the most worrisome complications of Chronic Kidney Disease (CKD). Numerous prospective studies have repeatedly documented an increase risk of morbidity and mortality associated with lower levels of hemoglobin (Hb). Hence the international guidelines on patient care suggest the use of Erythropoietin Stimulating Agents (ESA), iron, folates ...

Phase N/A

Studies of Elevated Parathyroid Activity

Patients with confirmed or suspected primary hyperparathyroidism or complications therefrom (such as postoperative hypoparathyroidism) will be admitted for diagnosis and treatment. The principal diagnostic components are calcium in serum and urine and parathyroid hormone in serum. Patients with moderately to highly severe primary hyperparathyroidism will be treated. Treatment will be ...

Phase N/A

Studies of Inherited Diseases of Metabolism

Familial multiple endocrine neoplasia type 1 (MEN1), familial hypocalciuric (or familial benign) hypercalcemia (FHH), hyperparathyroidism jaw tumor syndrome (HPT-JT), other causes of familial isolated hyperparathyroidism (FIH), and pseudohypoparathyroidism (PHP) are disorders of metabolism that are generally inherited in an autosomal dominant fashion. MEN1 is characterized by overgrowth and hyperfunction of ...

Phase N/A

Pilot Study: Hypovitaminosis D Hyperparathyroidism and Hypomagnesemia in Patients With Congestive Heart Failure

People with heart failure may have low magnesium and low vitamin D levels. They may also have abnormally high levels of parathyroid hormones. Magnesium and vitamin D are important chemicals that are not routinely measured in blood tests. We are studying how many people with heart failure have low levels ...

Phase N/A

The Effect of Parathyroidectomy on Renal Function Endothelial Function and Blood Pressure

Secondary hyperparathyroidism (HPT) is a known complication of chronic renal failure. Elevated concentrations of parathyroid hormone (PTH) play a role not only in the pathogenesis of renal bone disease, but also in the development of cardiovascular risk factors such as disturbed lipid metabolism, glucose intolerance, and hypertension. HPT is also ...

Phase N/A

Variables That Are Correlated to Developing Multiple Endocrine Neoplasia (MEN) and Pancreatic Neuroendocrine Tumors (PNET)

Researchers aim to identify somatic mutations and inherited genetic variants which may help predict the development of PNET in patients with hyperparathyroidism.

Phase N/A

Gene Expression in Hyperparathyroidism

Patient charts will be reviewed to collect demographic data, pre-operative and post-operative clinical and laboratory data, operative reports, and pathology reports. Archived formalin-fixed paraffin-embedded (FFPE) tissue blocks from surgical specimens of patients will be stained for parafibromin to evaluate for HRPT2 mutations.

Phase N/A

Surgery for Primary Hyperparathyroidism (pHPT) in Patients Older Than 65 Years Compared With Follow-up

The majority of patients diagnosed and operated due to primary HPT in Scandinavia are older than 65 years of age. The vast majority of the patients have mild aberrations of serum calcium (< 1.50 mmol/l ionized calcium), and some patients may even be asymptomatic. The present trial is designed to ...

Phase N/A

Cinacalcet Versus Parathyroidectomy in Peritoneal Dialysis Patients

Patients with severe secondary hyperparathyroidism (SHPT) are frequently complicated with vascular calcification. There is some suggestion that subtotal parathyroidectomy may reduce or stabilize vascular calcium scores in dialysis patients. Experimental data suggests that SHPT plays an important role in mediating uraemic arterial disease and that parathyroidectomy largely prevented the development ...

Phase N/A

Randall's Plaque Study: Pathogenesis and Relationship to Nephrolithiasis

In order to attempt to explain the pathogenesis of renal calculi, the investigators videotape and document the location and characteristics of each stone, papillae and calyces. One or more small papillary biopsies are taken for analysis to help determine the point of origin of the kidney stone and histological studies ...
