Implication

Ex vivo study demonstrates that neutrophils aggravate ischemia-reperfusion injury via oxygen metabolites in isolated rat kidneys, highlighting their direct role in renal reperfusion damage.

Key Points

To determine whether neutrophils aggravate functional and structural injury during reperfusion following renal ischemia.
Perfused isolated ischemic and nonischemic rat kidneys with purified human neutrophils or buffered albumin alone.
Assessed injury mechanisms using the neutrophil activator phorbol myristate acetate, oxygen metabolite-deficient neutrophils from a chronic granulomatous disease patient, and the oxygen metabolite scavenger catalase.
Reperfusion of ischemic kidneys with neutrophils significantly reduced glomerular filtration rate (113 ± 7 vs. 222 ± 18 µl·min⁻¹·g⁻¹ without neutrophils; P < 0.01) and tubular sodium reabsorption (72 ± 2% vs. 90 ± 2%; P < 0.01), alongside vascular cell injury.
Addition of neutrophils did not injure nonischemic control kidneys unless phorbol myristate acetate was added to stimulate activation.
Co-administration of catalase or using oxygen metabolite-deficient neutrophils abolished the neutrophil-induced functional deficits in ischemic kidneys.
