Reduced Hepatic Synthesis of Calcidiol in Uremia [PDF]

Journal of the American Society of Nephrology, 2010
Calcidiol insufficiency is highly prevalent in chronic kidney disease (CKD), but the reasons for this are incompletely understood. CKD associates with a decrease in liver cytochrome P450 (CYP450) enzymes, and specific CYP450 isoforms mediate vitamin D(3) C-25-hydroxylation, which forms calcidiol. Abnormal levels of parathyroid hormone (PTH), which also

Undetectable serum calcidiol: not everything that glitters is gold [PDF]

Clinical Kidney Journal, 2012
There is an increased awareness of the adverse consequences of nutritional vitamin D deficiency. We report a patient with chronic tophaceous gout, chronic kidney disease (CKD) Stage 3/4 and undetectable serum calcidiol who developed severe hypercalcaemia upon vitamin D supplementation despite serum 25(OH) vitamin D within the normal range.

Improvements in the Simultaneous Determination of Calcidiol and Calcitriol in Human Serum or Plasma [PDF]

Clinical Chemistry and Laboratory Medicine, 1988
Technical improvements have been applied to reduce the time required for the determination of calcidiol and calcitriol in serum or plasma. The modifications include the use of Sep-Pak C18 cartridges for the extraction of calciol metabolites from serum instead of a classical liquid/liquid extraction, a considerable shortening of the HPLC purification ...
