  Purpose

Patients with impaired renal function are at elevated risk for development of contrast-medium induced acute kidney injury (CI-AKI). CI-AKI is associated with increased risk for cardiovascular morbidity and mortality. Effective CI-AKI prevention strategies are needed.

The RenPro-II-WINE Trial was designed to test the hypothesis whether moderate red wine consumption prior to contrast-medium use is effective in CI-AKI prevention.

Consecutive patients with impaired renal function undergoing elective coronary angiography will be assigned in one of four treatment arms: a. control patients receiving standard care b. patients receiving standard care plus red wine c. patients receiving standard care plus white wine d. patients receiving standard care plus beer This study will give important answers on how to prevent CI-AKI in patients with impaired renal function undergoing contrast media exposure.


Condition Intervention Phase
Chronic Renal Failure/ Kidney Disease Contrast-medium Induced Acute Kidney Injury Dietary Supplement: Red wine Dietary Supplement: White wine Dietary Supplement: Beer Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Randomized Controlled Study for Evaluation of the Impact of Red Wine, White Wine and Beer Intake on Contrast-Medium Induced Acute Kidney Injury

Further study details as provided by Dr. Fikret Er, University of Cologne:

Primary Outcome Measures:
  • CI-AKI incidence [ Time Frame: <48 hours after contrast-medium exposure ]
    Increment of serum-creatinin of 0.5 mg/dl or of at least 25% in 48 hours after contrast medium intake from baseline.


Secondary Outcome Measures:
  • Biomarkers assessing acute kidney injury [ Time Frame: <48 hours ]
    Changes of urinary neutrophil gelatinase-associated lipocalin (NGAL), serum creatinin and cystatine after coronary angiogram.
