Calcitriol is a hormone and the active form of vitamin D, normally made in the kidney. [8] [9] [10] It is also known as 1,25-dihydroxycholecalciferol.It binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. [11]
A diet high in sodium [21] and protein further increases the risk of IH. [22] Excessive protein intake may be associated with an enlarged kidney and the overproduction of calcitriol that acts on calcium absorption, causing more excretion of calcium in the urine. [1] Insufficient water or fluid intake also acts as a risk factor.
Renal osteodystrophy is usually diagnosed after treatment for end-stage kidney disease begins; however the CKD-MBD starts early in the course of CKD. [ 1 ] [ 6 ] In advanced stages, blood tests will indicate decreased calcium and calcitriol (vitamin D) and increased phosphate , and parathyroid hormone levels.
Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow. Calcitriol, the activated form of vitamin D, promotes intestinal absorption of calcium and the renal reabsorption of phosphate.
The severity of chronic kidney disease (CKD) is described by six stages; the most severe three are defined by the MDRD-eGFR value, and first three also depend on whether there is other evidence of kidney disease (e.g., proteinuria): 0) Normal kidney function – GFR above 90 (mL/min)/(1.73 m 2) and no proteinuria
All people with a GFR <60 mL/min/1.73 m 2 for 3 months are defined as having chronic kidney disease. [59] Protein in the urine is regarded as an independent marker for worsening of kidney function and cardiovascular disease. Hence, British guidelines append the letter "P" to the stage of chronic kidney disease if protein loss is significant. [60]

calcitriol (1,25-(OH) 2 vitamin D 3) levels are low or within the lower reference range. Most importantly, urinary loss of phosphate is above the reference range. [citation needed] The renal tubular reabsorption of phosphate (TRP) in X-linked hypophosphatemia is 60%; normal TRP exceeds 90% at the same reduced plasma phosphate concentration.
