Renal transplant recipients are at risk of developing bone abnormalities that result in bone loss and bone fractures. These are related to underlying renal osteodystrophy, hypophosphatemia, and immunosuppressive treatment regimen. Although bisphosphonates are useful in ameliorating bone mineral loss after transplantation, it is not known whether their use in renal transplant patients leads to e...

Changes in mineral and bone metabolism are prevalent in chronic kidney disease. There are several types of renal bone disease, called 'renal osteodystrophy (ROD)'. ROD includes osteitis fibrosa, osteomalacia, adynamic bone disorder, and mixed osteodystrophy. Osteitis fibrosa is high turnover bone due to secondary hyperparathyroidism. Osteomalacia is low turnover bone concomitant of increased os...

Parathyroidectomy (PTX) may cause low levels of PTH, leading to an excessive reduction of bone turnover, which is associated with poor outcomes in dialysis patients, including vascular calcification (VC). We aimed to prospectively investigate the impact of PTX on bone remodeling and its potential consequence on the progression of VC in hemodialysis patients. In this prospective study, 19 hemodi...

Zorab, P. A., Clark, S., Cotrel, Y., and Harrison, A. (1971). Archives of Disease in Childhood, 46, 828. Bone collagen turnover in idiopathic scoliosis estimated from total hydroxyproline excretion. The turnover of bone collagen is reflected by the 24-hour excretion of urinary total hydroxyproline. In idiopathic scoliosis there is an increase above normal in the turnover of bone collagen throug...

Recently, the clinical and experimental evidences that support the toxic effects of indoxyl sulfate, a protein-bound uremic toxin in chronic kidney disease (CKD) patients, has been discussed. In this panorama, the authors described several in vitro and in vivo studies, suggesting that indoxyl sulfate may play a part in the pathogenesis of low turnover bone disease. However, the discussion claim...

OBJECTIVE To assess the new quantitative bone scan parameters as markers of Charcot neuroosteoarthropathy (CNO) activity. RESEARCH DESIGN AND METHODS Forty-two patients with acute (n = 21) and nonacute (n = 21) CNO underwent quantitative bone scanning. Patients with acute CNO were followed for 3-12 months and bone scans were repeated after treatment. New quantitative parameters were assessed ...

BACKGROUND Hyperthyroidism is accompanied by osteoporosis with higher incidence of fracture rates. The present work aimed to study bone status in hyperthyroidism and to elucidate the impact of severity, duration, and etiology of hyperthyroidism on biochemical markers of bone turnover and bone mineral density (BMD). METHODS Fifty-two male patients with hyperthyroidism, 31 with Graves' disease ...

Plasma total versus bone alkaline phosphatase as markers of bone turnover in hemodialysis patients. Plasma bone-specific alkaline phosphatase (bAP) has been demonstrated to be more reliable than total alkaline phosphatases (tAP) in providing information about bone turnover in patients with metabolic bone diseases. This study surveyed 42 hemodialysis patients who underwent a systematic transilia...

PURPOSE To examine the influence of ovariectomy (OVX) on bone turnover and trabecular bone mass at the 3 clinically important skeletal sites in mature cynomolgus monkeys. MATERIALS AND METHODS Six female cynomolgus monkeys, aged 17-21 years, were randomized into 2 groups by the stratified weight: the OVX and sham-operation groups (n = 3 in each group). The experimental period was 16 months. L...
