Cross talk between the renin-angiotensin-aldosterone system and vitamin D-FGF-23-klotho in chronic kidney disease

Abstract
There is increasingly evidence that the interactions between vitamin D, fibroblast growth factor 23 (FGF-23), and klotho form an endocrine axis for calcium and phosphate metabolism, and derangement of this axis contributes to the progression of renal disease. Several recent studies also demonstrate negative regulation of the renin gene by vitamin D. In chronic kidney disease (CKD), low levels of calcitriol, due to the loss of 1-alpha hydroxylase, increase renal renin production. Activation of the renin-angiotensin-aldosterone system (RAAS), in turn, reduces renal expression of klotho, a crucial factor for proper FGF-23 signaling. The resulting high FGF-23 levels suppress 1-alpha hydroxylase, further lowering calcitriol. This feedback loop results in vitamin D deficiency, RAAS activation, high FGF-23 levels, and renal klotho deficiency, all of which associate with progression of renal damage. Here we examine current evidence for an interaction between the RAAS and the vitamin D-FGF-23-klotho axis as well as its possible implications for progression of CKD.

Cross talk between vitamin D (red), FGF-23-Klotho (yellow), and the RAAS (blue) in healthy subjects and patients with chronic kidney disease. In the normal situation (left panel), active vitamin D (1,25(OH)2 vitamin D), generated by renal 1-alpha hydroxylase, suppresses renal renin production. When the RAAS is not activated (low angiotensin II), renal klotho levels are sufficient to allow normal function of the FGF-23 receptor. Therefore, levels of FGF-23, a negative regulator of 1-alpha hydroxylase, are normal under these conditions. In chronic kidney disease (right panel), the RAAS, vitamin D, FGF-23 and klotho are concertedly disturbed. (1) Activity of 1α-hydroxylase is reduced due to nephron loss and high FGF-23 in CKD, leading to (2) reduced production of 1,25(OH)2-vitamin D, which in turn upregulates renal renin production. (3) The subsequent higher levels of angiotensin II cause renal klotho loss and (4) disrupted FGF-23 signaling, impairing phosphaturia and rising FGF-23 levels. RAAS activation, vitamin D deficiency, high FGF-23 levels and low renal klotho have all been associated with adverse renal outcome in CKD.
