OBJECTIVE
To evaluate, during the first postoperative year in obese pre-menopausal women, the effects of laparoscopic gastric banding on calcium and vitamin D metabolism, the potential modifications of bone mineral content and bone mineral density, and the risk of development of secondary
Obesity has been shown to be unfavorable to skeletal microarchitecture when assessed by trabecular bone score (TBS). The influence of adiposity on skeletal microstructure in primary hyperparathyroidism (PHPT) has not yet been evaluated.
To investigate the effect of obesity on TBS and bone mineral
The effect of calcium infusion was studied in patients with renal tubular acidosis (RTA) and secondary hyperparathyroidism. Both developed after jejunoileal bypass operation (JIB) for morbid obesity. In three of four cases the acidification defect was abolished, probably due to a decrease of serum
BACKGROUND
Both obesity (body mass index, BMI > or = 30 kg/m2) and Black race are associated with a higher risk of vitamin D deficiency and secondary hyperparathyroidism. We hypothesized the risk of hypovitaminosis D would therefore be extraordinarily high in obese Black adults.
OBJECTIVE
To study
OBJECTIVE
Obesity is associated with secondary hyperparathyroidism in the general population. The objective of this study is to explore whether the same association is present in patients with chronic kidney disease.
METHODS
Linear regression models were used to examine the association between
Obesity subjects individuals into metabolic and endocrine disorders. Thus obesity may increase the risk of vitamin D deficiency. This text aims at studying the prevalence of vitamin D deficiency and secondary hyperparathyroidism in obese children. In a non-randomized case control study on 52 obese
BACKGROUND
We sought to evaluate the influence of morbid obesity in patients undergoing parathyroidectomy for primary hyperparathyroidism (pHPT).
METHODS
All patients with pHPT who underwent parathyroidectomy at a single institution between July 2002 and October 2008 were included. Body mass index
BACKGROUND
A relationship between primary hyperparathyroidism (PHPT) and obesity has been observed but is incompletely understood. Furthermore, obesity has been associated with vitamin D deficiency, suggesting that the three conditions may be linked.
OBJECTIVE
We hypothesized that PHPT in morbidly
BACKGROUND
Metabolic bone disease is a potential complication of bariatric surgery. The aims of our study were to evaluate the effects of laparoscopic gastric bypass on calcium and vitamin D metabolism, and to identify patients at high risk to develop secondary hyperparathyroidism
OBJECTIVE
To investigate the effect of marked weight loss after long limb-biliopancreatic diversion (BPD-LL) on bone mass and serum calcium, 25-OH-vitamin D, and PTH levels in relation to calcium supplementation.
BACKGROUND
BPD is the most effective type of bariatric surgery, but it is followed by
Gastric exclusion has been introduced as a surgical treatment for morbid obesity. We describe two women who had undergone gastric bypass for obesity with metabolic bone disease and secondary hyperparathyroidism. In one patient transiliac bone biopsy after double tetracycline labelling demonstrated
With over 110,000 bariatric operations performed in the United States annually, it is important to understand the biochemical abnormalities causing endocrine dysfunction associated with these procedures. Here we compare 2 malabsorptive procedures, duodenal switch and Roux-en-Y gastric bypass, to
BACKGROUND
Obesity has been associated with elevated serum PTH (sPTH) in the general population. Obesity may also alter the clinical presentation in patients with primary hyperparathyroidism (PHPT).
OBJECTIVE
The objectives of the study were to compare the clinical presentation of obese (OB) vs
BACKGROUND
Morbidly obese patients have been reported to present with vitamin D insufficiency and secondary hyperparathyroidism. We assessed whether bariatric surgery alters the 25-hydroxyvitamin D (calcidiol) and intact parathyroid hormone (iPTH) levels in patients presenting with morbid
In order to test the relation between obesity and the secondary hyperparathyroidism found in markedly overweight subjects, 24 morbidly obese patients were studied before and after a weight loss of 35.9 kg obtained by a nutritionally adequate, intermittent very-low-calorie diet. Overweight was
