Improvement in the vitamin D status i.e. total serum 25-hydroxyvitamin D in children and adults has been associated with reduced risk of upper respiratory tract infections including influenza A infection. The rationale for giving 25(OH)D3 rather than vitamin D3 is to rapidly improve the vitamin D
The goal of this study is to establish the effect of the compensation of vitamin D deficiency in the treatment of drug-resistant epilepsy with a high level of evidence in a large population. For that, the investigator aim to perform a controlled multicentre prospective double-blind randomized study
Introduction:
hCG signals through the LHCGR receptor and is know to stimulate testosterone production. hCG stimulation tests are therefore used to evaulate the capacity of the testis to respond to LH/hCG and thereby determine the degree og gonadal insufficiency and need for testosterone
This is a 2-year single-arm intervention study of which intravenous paricalcitol will be provided as a second-line treatment to 30 chronic hemodialysis patients with severe SHPT (defined as intact parathyroid hormone [iPTH] ≥ 800pg/mL) resistant to existing vitamin D analogs treatment (including
DETAILED DESCRIPTION
Introduction: Vitamin D is a fat soluble vitamin and it affects multiple systems of our body. It not only plays a key role in musculoskeletal system but also works on our immune and cardiovascular systems. Because of its wide range of anti-inflammatory and metabolic properties,
The most commonly used measurement of vitamin D status is serum 25-hydroxyvitamin D (25(OH)D). However there is no clear consensus on the level of 25(OH)D required to protect against adverse effects of deficiency.
One approach is to define deficiency is the level of 25(OH)D at which there is a
Introduction:
Vitamin D is a versatile signaling molecule with a well-established role in the regulation of calcium homeostasis and bone health. The spectrum of vitamin D target-organs has expanded and it has been suggested that vitamin D influences the immune system, endocrine organs such as
The study evaluates if short-term treatment with calcimimetics may be used for patients with PHPT as a relevant guide in the decision of when to choose parathyroid surgery, by predicting the outcome of surgical treatment.
120 ± 2 patients with primary hyperparathyroidism scheduled for parathyroid
Vitamin D Supplementation is a practical and inexpensive intervention which is safe, readily available and clinically indicated. Substantial recent evidence suggests vitamin D may modify inflammatory pathways in CKD. There is a high probability of benefit and a low probability of harm for this
The prospective pilot study is designed to evaluate vitamin D status pre-operatively and post-operatively in 37 female patients undergoing either Roux-en Y gastric bypass or sleeve gastrectomy at The Methodist Hospital with 32 patients expecting to complete the 12 week trial. Women scheduled for
Calciphylaxis or calcific uremic arteriolopathy is an infrequently occurring although debilitating vasculopathy seen primarily in patients with end stage renal disease (ESRD) which almost always affects the skin. It has a prevalence rate ~4 % in long term hemodialysis patients, with 1-year survival
Introduction:
Primary hyperparathyroidism (PHPT) is the third most frequent endocrine disorder, after diabetes mellitus and thyroid disorders, that predominantly affects postmenopausal women, with an incidence of 1 -5 in 1000 people. It can occur at any age though young people are rarely affected.
The scientific purpose of this study is to obtain data on the use of sVDRA(Selective Vitamin D Receptor Activator) in real-life clinical practice. This study will allow us to observe drug effectiveness in a distinct geography. Treatment effects, as well as maintenance of the results will be recorded
A.1.a. Introduction This is a prospective, randomized, double-blind clinical trial designed to evaluate the effect of 24 months of supplementation with vitamin D3 and calcium on bone mass accrual in HIV-infected children and adolescents.
A.1.b. Subject recruitment i. HIV-infected subjects on will be
End-stage renal disease (ESRD) is a state of increased arterial stiffness of extensive vessel calcifications, compared with the non-renal population. Both arterial stiffness and arterial calcifications are potent predictors of all-cause and cardiovascular mortality in ESRD patients. Underlying
