290 Relationship between serum 25-hydroxyvitamin D (25(OH)D) level and parathyroid hormone (PTH) level in adults with cystic fibrosis

The serum level of 25-hydroxyvitamin D for maximal suppression of parathyroid hormone in children: the relationship between 25-hydroxyvitamin D and parathyroid hormone

PURPOSE Serum level of 25-hydroxyvitamin D (25-OHD) is considered as the most appropriate marker of vitamin D status. However, only a few studies have investigated the relationship between 25-OHD and parathyroid hormone (PTH) in children. To this end, this study was aimed at evaluating the lowest 25-OHD level that suppresses the production of parathyroid hormone in children. METHODS A retrosp...

Association between Serum 25-Hydroxyvitamin D Level and Rheumatoid Arthritis

The objective of this study is to examine and evaluate whether serum 25(OH)D is associated with disease activity in patients with rheumatoid arthritis (RA). Our results suggested that serum 25(OH)D in RA groups has significant lower level (35.99 ± 12.59 nmol/L) than that in the normal groups (54.35 ± 8.20 nmol/L, P < 0.05). Based on the DAS28, patients with RA were divided into four subgroups, ...

Serum 25-hydroxyvitamin D and parathyroid hormone exhibit threshold behavior.

The Relationship Between Parathyroid Hormone and 25-Hydroxyvitamin D During and After Pregnancy.

We evaluated the effects of supplementation with DHEA (in elderly men and women) and testosterone (in elderly men) on postprandial or iv insulin suppression of lipolysis. We found no effect of these hormones on systemic lipolysis.

The relationship between hemoglobin level with PTH level and dialysis adequacy in chronic hemodialysis patients

Background: The role of high levels of parathyroid hormone in the development of anemia either directly or by mediating mechanisms is unclear, and there is a controversy about the pathophysiological role of parathyroid hormone (PTH) in the development and intensification of anemia associated with renal disease. The aim of this study was to investigate the relationship between anemia and parathy...
