Effect of Vitamin D Supplement on Inflammation Markers in High-Risk Cardiovascular Patients With Chronic Kidney Disease (VINCA-CKD)

May 13, 2014 updated by: Thomas Jefferson University

The Effect of Vitamin D Supplementation on Markers of Inflammation in High-Risk Cardiovascular Patients With Low Levels of Serum 25-Hydroxyvitamin D

The purpose of this study is to determine if vitamin D supplementation changes the results of certain tests associated with inflammation in the body using an oral, synthetic form of vitamin D called paricalcitol.

Study Overview

Detailed Description

Vitamin D deficiency is common and has been associated with an increased risk of heart disease. In patients with the combination of kidney disease and heart disease, inflammation is thought to contribute to a high rate of cardiac events. Less is known about the effects of vitamin D supplementation on certain tests associated with inflammation in the body.

  • High Sensitivity C-reactive Protein (hs-CRP) ≥ 2.0 mg/L
  • History of stage 3 or 4 chronic Kidney disease (CKD) defined as an glomerular filtration rate (eGRF) by the Modification of Diet in Renal Disease (MDRD) formula of 15-60 mL/min/1.73 m2
  • Low level of serum 25-hydroxyvitamin D (<30ng/mL)
  • Evidence of secondary hyperparathyroidism defined as intact parathyroid hormone (iPTH) level > 70 pg/mL
  • Stable dose of statin and/or other lipid lowering therapy (ie: ezetimibe, fibrates, bile acid sequestrants nicotinic acid, fish oil) for 12 weeks prior to enrollment without known plans for change to current therapy during the study period

Exclusion Criteria:

  • History of myocardial infarction, stroke, or cardiac surgery within 6 months of enrollment
  • History of carotid artery surgery
  • Planned cardiovascular surgery or procedure, with the exception of permanent pacemaker placement, in the next 18 months.
  • Use of vitamin D or calcium supplementation within the past 12 weeks with the exception of calcium containing phosphate binders and a daily multivitamin containing ≤ 400 IU of vitamin D
  • Hypercalcemia (as defined by the laboratory upper limit of normal ) or hyperphosphatemia (≥ 5.5 mg/dL)
  • Plan to initiate renal replacement therapy (dialysis) during the study
  • History of left ventricular systolic dysfunction with an ejection fraction <50% or history of New York Heart Association (NYHA)functional Class II-IV congestive heart failure
  • Uncontrolled blood pressure, defined as systolic blood pressure greater than 160 mmHg and diastolic blood pressure greater than 100 mm Hg at the screening visit
  • Uncontrolled diabetes, defined as hemoglobin A1C ≥ 10.0
  • History of any surgery within the past 3 months or known to be planned during the study period
  • History of malignancy within the past 5 years with the exception of non-melanoma (ie: squamous cell or basal cell) skin cancer

  • History of renal or other organ transplant and/or immunosuppressed state (ie immunosuppressive therapy or condition such as HIV)
  • History of any other condition, that in the opinion of the investigators renders it unsafe for the subject to be enrolled
  • For woman able to become pregnant, unwillingness to use birth control
  • Participation in another clinical trial
