New pharmacologic options for renal preservation

Abstract:
The understanding of the cause and pathophysiology of renal failure has guided the rational development of pharmacologic renoprotective strategies. Although traditionally anesthesiologists have focused on renal hemodynamic derangements, newer information suggests that cellular interactions amplify and perpetuate the insult. Consequently, the potential renoprotective armamentarium not only encompasses the more traditional vasoactive agents but also therapeutic approaches that may modify the cellular response to injury. Although few of these agents have reached the clinical arena, preliminary work suggests that this new approach to renal injury and protection may be promising.
Insights
Pharmacologic strategies for renal failure are evolving beyond hemodynamics to include cellular interactions. Newer approaches targeting cellular responses show promise for protecting kidneys from injury.
Area of Science:
- Nephrology
- Pharmacology
- Anesthesiology
Background:
- Understanding renal failure pathophysiology guides renoprotective strategies.
- Traditional focus on renal hemodynamics is expanding to include cellular mechanisms.
- Cellular interactions play a role in amplifying and perpetuating kidney injury.
Purpose of the Study:
