Summary

In recent years, diabetic nephropathy, which may lead to dialysis treatment, is the most prevalent underlying disease of people in developed countries. A wide range of studies have been carried out, from various points of view, to understand the progress of renal dysfunction in diabetic nephropathy.

Fibroblast growth factor 23 (FGF-23) is a primary regulator of renal phosphate excretion. FGF23 is inversely associated with the GFR, a relationship underlying a fundamental mechanism for maintaining serum phosphate constancy during CKD progression. Such an adaptation may have deleterious trade-offs because, independently of serum phosphate, high FGF23 signals a high risk of death in ESRD patients. Some studies showed that there is relationship between FGF-23 levels and proteinuria in CKD patients.

There is no data about the effects of calcium channel blocker on FGF23 levels in diabetic patients with proteinuria. The aim of this study was to find out whether the beneficial effects of calcium channel blocker in diabetic proteinuria has any relation with the alteration of FGF-23 levels. The investigators searched for the effects of calcium channel blocker amlodipine on the clinical and laboratory parameters of diabetic patients with proteinuria.

The investigators registered the study 'The effect of renin angiotensin system Blockage (RAS), calcium channel blocker and combined drugs on TWEAK, PTX3 and FMD levels in Diabetic Proteinuric Patients with Hypertension' (ClinicalTrials.gov Identifier:NCT00921570). The investigators will use the samples of the some patients for this study. The investigators also registered the study 'FGF-23 and Endothelial Dysfunction in Diabetic Proteinuric Patients' (ClinicalTrials.gov Identifier: NCT01703234). The investigators will combine these two registered studies (NCT00921570 and NCT01703234) in one study.
