VITamine D Supplementation in RenAL Transplant Recipients - VITALE
Prospective Double Blind Multicentre Randomized Trial of Vitamine D Estimating the Profit of a Treatment by Vitamin D3 at the Dose of 100000 UI by Comparison With a Treatment in the Dose of 12 000 UI at Renal Transplanted Patients

It has been proposed that the intake of high dose of cholecalciferol may have beneficial non classical effects (beside bone health). This could include the reduction of type 2 diabetes mellitus, cardiovascular diseases, cancers, autoimmune and infectious diseases. These pleiotropic effects are mostly documented by observational and experimental studies or small intervention trials. In renal transplant recipients, vitamin D insufficiency, defined as circulating 25(OH)vitamin D (25OHD) less than 30 ng/mL, is a frequent finding and this population is at risk of the previously cited complications.The primary purpose of this study is to compare the effects of high dose vs. low dose of cholecalciferol on a composite endpoint consisting in de novo diabetes mellitus, cardiovascular diseases, de novo cancer and patient death.Renal transplant recipients between 12 and 48 months after transplantation will be randomized to blindly receive either high or low dose of cholecalciferol with a follow-up of 2 years.

Rationale :

Vitamin D cannot be considered any more as only necessary to prevent rickets or osteomalacia. Calcitriol produced in the kidney is known to have classical endocrine PHOSPHOCALCIC properties. More recently, vitamin D has been shown to play an important role in reducing the risk of many chronic diseases including type 2 diabetes mellitus, cardiovascular diseases, cancers, autoimmune and infectious diseases. These effects may be secondary to local production of calcitriol and to its autocrine and paracrine actions on cellular proliferation and differentiation, apoptosis, insulin and renin secretion, interleukin and bactericidal proteins production. These pleiotropic effects are mostly documented by observational and experimental studies or small intervention trials that most often evaluated intermediate parameters. In renal transplant recipients, vitamin D insufficiency (circulating 25OHD<30 ng/mL or 75 nmol/L) , is a frequent finding with more than 80% of patients displaying this profile.

Objective:

Primary objective: compare the effects of high dose vs. low dose of cholecalciferol on a composite endpoint including

  • De novo diabetes mellitus (fasting glycemia > 7 MMOLES/l or glycemia > 11 MMOLES/l)
  • Cardiovascular complications (acute coronary heart disease, acute heart failure, lower-extremity arterial disease, cerebrovascular disease).
  • De novo cancer,
  • Patient death.

Secondary objectives : compare the effects of high dose vs. low dose of cholecalciferol on

  • The occurrence of each event constituting the primary endpoint
  • Blood pressure and blood pressure control (number and dosage of antihypertensive drugs)
  • Echocardiography findings
  • Infection including opportunistic (CMV, pneumocystis, nocardial infection, cryptococcal infection, aspergillosis)
  • Acute rejection episode
  • Renal allograft function including estimated glomerular filtration rate and proteinuria - Graft survival
  • PHOSPHOCALCIC biological and clinical relevant parameters : Evolution of serum 25OHD, calcaemia, phosphataemia, serum PTH, bone mineral density and incidence of fractures
  • Renal lithiasis
