Pituitary Disorders Clinical Trials

A research study is evaluating an investigational medication for Cushing syndrome in adults with type 2 diabetes and/or high blood pressure.  

Objective To determine the metabolic effects of the adrenalectomy in subclinical Cushing's syndrome of adrenal incidentaloma. Methods 234 subclinical cushing syndrome and adrenal incidentaloma will be randomly assigned into two groups(e.g adrenalectomy group and conservative treatment group).

The first phase of this study will be to contact all subjects in the cohort by a mailing introducing them to the study. This will be followed by a phone call and administration of a questionnaire by phone or by mail. The questionnaire will collect current information on acromegaly treatment, ...

Growth hormone (GH) and Insulin-Like Growth Factor-1 (IGF-1) are important regulators of bone modeling and remodeling, fundamental to maintenance of normal skeletal integrity. In acromegaly, a disease characterized by longstanding exposure to excess GH and IGF-1, these hormones induce marked skeletal changes. Most dual energy X-ray absorptiometry (DXA) studies report ...

PROTOCOL I: Prospective Study of the outcome of conservative non-surgical management of patients with asymptomatic, clinically non-functioning (CNF) pituitary lesions. This protocol will evaluate prospectively the outcome of non-surgical management of clinically non-functioning pituitary lesions that do not appear to need surgery as their initial therapy. The overall design consists ...

Background Wolfram syndrome (OMIM #222300) is an autosomal recessive disorder characterized by insulin dependent diabetes mellitus (DM) in the first decade of life, followed by optic atrophy (OA), blindness, and deafness. Death from widespread neurodegeneration occurs in the third or fourth decades. Postmortem studies revealed a non-autoimmune loss of pancreatic ...

The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity through computerized collection of comprehensive demographic, therapeutic, pathologic and outcome information on patients harboring pituitary mass lesions of all types.

The study will begin when the combination of Sandostatin LAR or Somatuline and pegvisomant is first administered. Study visits will occur every 4 weeks from the start of the study. However, for subjects who cannot make every study visit due to distance, the study team will facilitate monthly blood draws ...

Acromegaly is a rare disorder characterized by excessive production of growth hormone most often by a pituitary adenoma. A pituitary adenoma is a tumor, almost always benign or non-cancerous, that grows on the pituitary, a small gland located at the base of the brain. Treatment of acromegaly usually involves surgery, ...

24h-Urine free cortisol (24h-UFC) and other screening tests may turn out normal in Cushing's syndrome (CS) patients, probably due to high variability and cyclicity in cortisol secretion. To rule out cyclic cortisol secretion, the recommendation is to repeat 24h-UFC measurements on different and several occasions. As 24h-UFC is technically inconvenient, ...
