A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism Clinical Trials Information presented on Clinical Trials Search is not designed to be a substitute for proven healthcare advice, travels to or treatment by using a genuine medical doctor. We are not physicians. Always confer with your doctor on A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism Clinical research trials and A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism healthcare trials take place in many of cities across the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally evaluate the effectiveness of new drugs. The function of the studies / undertakings is to answer specific human medical questions. Clinical trials are a popular means for mDs, government agencies, and private sector companies to find treatments for all forms of conditions, including A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism. A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism Clinical Trials and other clinical trials allow for volunteers to access medical treatment alternatives before they are available to the masses. Many times the test subjects undergo treatment for without cost, and occasionally they are compensated for their time. Occasionally there is a cost for a A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism clinical trial. Test subjects oftentimes recieve the best healthcare possible for their A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism condition. Hazards are a reality, nonetheless, and might include additional or frequent doctor trips, healthcare hazards (perhaps life-jeopardizing), and/or the treatment being ineffective. Trials are federally regulated with rigid guidelines to protect clinical trials subjects.

A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism



A Randomized Study of Surgery vs No Surgery in Patients with Mild Asymptomatic Primary Hyperparathyroidism

For Condition: Hyperparathyroidism
Status: No longer recruiting
Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) , Henry Ford Hospital
Synopsis: OBJECTIVES: I. Assess the efficacy of surgery vs no surgery in patients with mild asymptomatic primary hyperparathyroidism. II. Assess the quality of life, morbidity, and mortality of these patients.
Details: PROTOCOL OUTLINE: This is a randomized, multicenter study. Patients are stratified by gender. Patients are randomized to receive surgery or follow up without surgery. Patients receive parathyroidectomy (current standard care) or long term follow up without parathyroidectomy. Quality of life is assessed before the study and then every 6 months. All patients are followed every 6 months until death.
Eligibility:
Study Type:  Interventional, Treatment, Randomized
Minimum Age/Maximum Age: 50 Years/75 Years
Genders: Both
Protocol Entry Criteria: PROTOCOL ENTRY CRITERIA: --Disease Characteristics-- Histologically diagnosed mild asymptomatic primary hyperparathyroidism Persistent albumin adjusted serum calcium between 10.1-11.5 mg/dL for at least 3 months Intact parathyroid hormone greater than 20 pg/mL No other cause for hypercalcemia No family history of primary hyperparathyroidism, primary endocrine neoplasia, or hypocalciuric hypercalcemia Bone mineral density of the forearm no greater than 2.0 SD units below the expected value for sex, age, and race No phalangeal subperiosteal resorption on hand x-rays --Prior/Concurrent Therapy-- Radiotherapy: No history of childhood irradiation to head and neck Surgery: No thyroid disease requiring surgical intervention Other: No prior glucocorticoid or anticonvulsant drug therapy Concurrent thiazide diuretic therapy for hypertension must be changed to nonthiazides --Patient Characteristics-- Menopausal status: At least 5 years postmenopausal Renal: At least 2 years since prior nephrolithiasis Creatinine no greater than 1.5 mg/dL Creatinine clearance at least 70% (age adjusted) Cardiovascular: No unexpected finding on echocardiogram that will interfere with surgical intervention Other: Living within 150 mile radius of downtown Detroit No concurrent participation in other clinical trials No concurrent polyuria, polydipsia, anorexia, nausea, or vomiting At least 12 months since prior pancreatitis No concurrent symptomatic peptic ulcer disease No objective muscle weakness No history of nontraumatic vertebral or hip fractures No vertebral compression fractures No urolithiasis on x-ray of abdomen
