II. Assess whether calcium-regulated changes in parathyroid hormone secretion predict changes in bone formation.
III. Characterize the response to GH in cancellous bone and in growth plate cartilage in patients with secondary hyperparathyroidism during calcitriol therapy.
PROTOCOL OUTLINE: This is a randomized study. Patients are stratified by bone lesion turnover and secondary hyperparathyroidism.
Patients in the first group are treated with recombinant human growth hormone subcutaneously every day for 8 months.
Patients in the second group are treated with calcitriol for 8 months, administered as a daily oral dose or an intraperitoneal dose three times a week.
Patients in the third group are treated with growth hormone and calcitriol (same dosages as above).
A control group does not receive any hormonal therapy.
Allocation: Randomized, Primary Purpose: Treatment
calcitriol, growth hormone

The aim of the study is to 1. To describe the bone morphology in patients with reduced renal function and high or low parathyroid hormone (PTH) respectively. 2. To investi...
We, the researchers, have found that growth hormone deficiency is very common in patients with pseudohypoparathyroidism type 1a. These patients typically are short and obese. Some of th...
There are two major goals of this project: 1. Comparison of DXA and QCT for diagnosis of bone loss in CKD-5 patients and determination of the prevalence of low bone turnover in CKD...
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Calcit...
RATIONALE: Combining calcitriol with dexamethasone may increase the effectiveness of therapy by making cancer cells more sensitive to dexamethasone. PURPOSE: Phase I trial to study the ef...
A 27-year-old man, with a history of chronic renal failure due to obstructive uropathy, treated with hemodialysis and awaiting kidney transplantation, presented with tertiary hyperparathyroidism. Desp...
The anti-inflammatory role of the active metabolite of vitamin D, namely 1, 25-dihydroxyvitamin D (calcitriol), has been reported in multiple sclerosis (MS). Moreover, recent studies have shown that f...
BACKGROUND Calcitriol (1 alpha, 25-dihydroxy vitamin D3) is a good vitamin D supplement but can cause hypercalcemia. Whereas, 22-oxa-1 alpha, 25-dihydroxy vitamin D3 (22-oxa-calcitriol) has less hyper...
Clinical use of calcitriol (1,25-dihydroxyvitamin D) as an anticancer agent is currently limited by the requirement of supraphysiological doses and associated hypercalcemia. Nanoencapsulation of calci...
The anti-obesity actions of growth hormone (GH) led us to investigate if GH signaling is able to regulate beige/brite fat development of white adipose tissue (WAT).
The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (CALCIFEDIOL). Its production is stimulated by low blood calcium levels and parathyroid hormone. Calcitriol increases intestinal absorption of calcium and phosphorus, and in concert with parathyroid hormone increases 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.
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.
A 191-amino acid polypeptide hormone secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR), also known as GH or somatotropin. Synthetic growth hormone, termed somatropin, has replaced the natural form in therapeutic usage such as treatment of dwarfism in children with growth hormone deficiency.
A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.
Endocrine disorders are grouped into two categories: hormone imbalance - when a gland produces too much or too little of an endocrine hormone development of lesions (such as nodules or tumors) in the endocrine system, which may or may not affect...
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
