[Intestinal absorption of Ca47 in chronic renal insufficiency before and after treatment with 1,25 dihydroxycholecalciferol]. 1979

A Vattimo

The effects of vitamin D3 follow its metabolisation in the liver and then in the kidney. Its most active metabolite is 1,25 (OH)2D3, produced by the liver precursor 25(OH)D3. In chronic renal insufficiency, demineralising osteopathy can be corrected by administering 1,25 (OH)2D3 to make up for its under-production by the kidneys. An assessment if is made of 47Ca intestinal transport in patients with chronic renal insufficiency before and after such treatment. It was found that the effects of the metabolite on calcium transport were dose-dependent.

D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D007676	Kidney Failure, Chronic	The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
