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

2014-08-27 03:15:11 | BioPortfolio

Summary

General consensus and contemporary guidelines, recommend surgery for primary hyperparathyroidism (pHPT)for all patients below the age of 50, for patients with pronounced hypercalcemia and for patients with organ complications to the disease (osteoporosis and decreased renal function).

The purpose of this study is to determine if surgery for pHPT, is appropriate for patients with mild hypercalcemia older than 65 years of age.

The hypothesis of the study is that surgery for pHPT in patients older than 65 years of age, and with mild hypercalcemia, will increase bone density and hence decrease future risk for fragility fractures compared to patients with follow-up only.

Description

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 clarify the indications for surgical treatment in this large subgroup of patients.

Medical and Biotech [MESH] Definitions

A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.

A condition of abnormally elevated output of PARATHYROID HORMONE due to parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. It is characterized by the combination of HYPERCALCEMIA, phosphaturia, elevated renal 1,25-DIHYDROXYVITAMIN D3 synthesis, and increased BONE RESORPTION.

Abnormally elevated PARATHYROID HORMONE secretion as a response to HYPOCALCEMIA. It is caused by chronic KIDNEY FAILURE or other abnormalities in the controls of bone and mineral metabolism, leading to various BONE DISEASES, such as RENAL OSTEODYSTROPHY.

Pathological processes of the PARATHYROID GLANDS. They usually manifest as hypersecretion or hyposecretion of PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.

Decalcification of bone or abnormal bone development due to chronic KIDNEY DISEASES, in which 1,25-DIHYDROXYVITAMIN D3 synthesis by the kidneys is impaired, leading to reduced negative feedback on PARATHYROID HORMONE. The resulting SECONDARY HYPERPARATHYROIDISM eventually leads to bone disorders.
