Aldosterone Blockade Added to Renin-Angiotensin System Blockade to Reduce Albuminuria—A Path for Improved Renoprotection?

      In patients with diabetic nephropathy, lowering of albuminuria is an important short-term goal of treatment, as albuminuria is regarded as a surrogate for renoprotection.

      Reduction in albuminuria predicts a beneficial effect on diminishing the progression of human diabetic nephropathy during antihypertensive treatment.
      The most effective intervention to reduce albuminuria is blockade of the renin-angiotensin system (RAS), using angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB), as has been common practice since focused studies in 2001 showed a long-term renal and cardiovascular benefit of this treatment approach in patients with proteinuric type 2 diabetes.

      However, what has also been evident ever since is the fact that many patients carry residual renal risk, and that further reduction of albuminuria and renal and cardiovascular risk would be potentially beneficial.
