Brief Summary:

Background Arteriovenous (AV) fistula is the most common vascular access for long-term hemodialysis in the end-stage renal disease (ESRD) patients. About 25% of these patients are diabetes mellitus. However, the effects of hyperglycemia on the vascular function of arteriovenous fistula are still remained unclear. Studies have shown that blood flow in the AV fistula is significantly reduced in patients with diabetes mellitus. Diabetic patients also require a longer period of time for the maturation of AV fistula, and have slightly higher complication rate than non-diabetic patients. Statins have been widely shown to mediate several important pleiotropic effects in the improvement of vascular endothelial dysfunction, attenuation of inflammatory responses, stabilization of atherosclerotic plaques, inhibition of vascular smooth muscle proliferation, and modulation of procoagulant activity and platelet function.Our experimental studies in diabetic animals demonstrate that administration of a water-soluble statin rosuvastatin significantly improves the fistula flow, vascular function and luminal dilatation of AV fistula in diabetic rats by suppression of vascular oxidative stress and inflammatory load.

Study hypothesis The central hypothesis of this research project is rosuvastatin mediates pleiotropic protective effect on vascular endothelial function and suppresses the regional pro-inflammatory reaction in the vasculature, therefore administration of rosuvastatin during the perioperative period of creation of native AV fistulas in diabetic patients with ESRD may potentiate the vascular function and reduce the primary failure rate of AV fistulae.

Arteriovenous fistula surgery was performed after 1-week treatment with placebo or Rosuvastatin (randomized, double blind). The intervention drug treatment continues for 3 more weeks after creation of AV fistula.
Other Name: Crestor

Active Comparator: Rosuvastatin
Rosuvastatin (CrestorÒ, Astrazeneca) 5mg once daily for 4 weeks (1 week before operation and 3 weeks after creation of AV fistula)
Drug: Rosuvastatin
Arteriovenous fistula surgery was performed after 1-week treatment with placebo or Rosuvastatin (randomized, double blind). The intervention drug treatment continues for 3 more weeks after creation of AV fistula.
Other Name: Crestor

Primary Outcome Measures :
  1. Primary patent rate of AV fistula [ Time Frame: 6 months after operation ]
    The definition of primary patency of an AV fistula is defined as successful cannulation of the fistula for first hemodialysis treatment (first dialysis session)(reference: BioMed Central Nephrology 2013;14:79). Administration of rosuvastatin protects the endothelial function in the AV fistula and restores the blood flow rate in the shunt of diabetic patients with ESRD, thereby improves the primary patent rate and early maturation of these fistulas

Secondary Outcome Measures :
  1. Composite outcome measurement of the overall shunt-related complication rate [ Time Frame: 6 months after operation ]
    The most commonly shunt-related complications are formation of aneurysms, failure of shunt to mature, and development of thrombosis in AV fistula (Ann Vasc Surg 2012;26:680). The occurrence of shunt-related complications usually require surgical reintervention. Administration of rosuvastatin improves the vascular function of AV fistulas in diabetic patients with ESRD, therefore reduces the overall shunt-related complication rate and the requirement for surgical re-interventions.

Other Outcome Measures:
  1. Composite outcome measurement of systemic pro-inflammatory response [ Time Frame: 6 months after operation ]
    Systemic proinflammatory response is determined by measuring blood concentrations of monocyte chemo-attractant protein (MCP)-1, interleukin (IL)-1 beta, IL-6 and tumor necrosis factor (TNF)-alpha, and the numbers of circulating endothelial progenitor cells (EPCs). Administration of rosuvastatin is associated with reduction of the systemic pro-inflammatory response and oxidative stress (levels of proinflammatory cytokines and other mediators in the circulation) in diabetic patients with ESRD. On the other hand, administration of rosuvastatin may mobilize the bone marrow-derived EPCs into systemic circulation, and the number of these circulating endothelial progenitors may provide prognostic value to the outcomes of AV fistula.

Plan Description: The Ethical committee in National Cheng Kung University Hospital approved major modification of a reduction of case collection from 80 to 60 cases on 2018-8-9. The study had recruited a total of 60 cases in the trial before 2018-12-31. The results were under analysis by the statistician. Moreover, exposure of the treatment group and placebo group were not performed until after completion of data analysis by the statistician in early February. The results might be revealed as appropriate in the website.
