Plain English summary of protocol
Background and study aims
Contrast is a form of dye that improves the visibility of organs during diagnostic and treatment procedures. Contrast can also cause damage to the kidneys, called contrast-induced nephropathy (CIN), by interrupting the kidneys’ blood flow. Remote Ischemic PreConditioning (RIPC) is a new treatment which involves repeatedly inflating a blood pressure cuff on the upper arm, causing reduced blood flow in the arm, which sends a signal that may protect the kidneys from reduced blood flow. The aim of this study is to evaluate the effect of RIPC in patients at a high risk of CIN.
Who can participate?
Patients aged over 18 who are undergoing diagnostic/treatment contrast procedures, and who are at a high risk of CIN.
What does the study involve?
Participants are randomly allocated to either the experimental group or the control group. In the experimental group patients undergo RIPC - four cycles of inflating and deflating a blood pressure cuff on the forearm. The control group receives the same procedure but the blood pressure cuff does not inflate to the necessary pressure (sham/dummy preconditioning). All participants provide blood and urine samples and complete a short questionnaire.
What are the possible benefits and risks of participating?
We expect that RIPC will be a non-invasive, simple, low-cost and safe method to reduce CIN in high-risk patients. RIPC is considered safe and as far as we know there are no complications.
Where is the study run from?
Radboud University Medical Center (Netherlands).
When is the study starting and how long is it expected to run for?
October 2012 to October 2013.
Who is funding the study?
Radboud University Medical Center (Netherlands) and Cook Medical.
Who is the main contact?

| Intervention | The researcher performs the sham preconditioning or ischemic preconditioning procedure. RIPC will be applied by 4 cycles of 5 minutes inflation and 5 minutes deflation of a standard blood pressure cuff around the upper arm at a pressure of the actual systolic blood pressure plus 50 mmHg. Sham preconditioning will be applied in a similar fashion as the RIPC stimulus, but the blood pressure cuff is inflated to the actual diastolic blood pressure minus 10 mmHg. |
