The role of pharmacological preconditioning in renal ischemic and reperfusion injury

Abstract

Renal ischemic and reperfusion injury resulting in acute renal failure is a multidisciplinary problem at the junction of pathophysiology, transplantology, urology, nephrology, cardiac surgery and pharmacology. One of renal protection strategies is using the phenomenon of preconditioning. Preconditioning is one of the ways to adopt a tissue to repeated short-term effects of damaging factors to induce an enhanced tolerance to the long period of hypoxia and/or ischemia. There are multiple cellular and molecular mechanisms of the renal protective effects of preconditioning stimuli, but the key effectors and signaling molecules are ATP-dependent potassium channels, nitric oxide synthase, nitric oxide, and mitochondrial pore. Contradictory data on the protective effect of ischemic preconditioning allow searching for approaches to pharmacological correction of ischemic and reperfusion injuries. The article provides data on possible ways of using erythropoietin, darbepoetin and phosphodiesterase 5 inhibitors.
