BackgroundThe ischemia-reperfusion injury (IRI) is unavoidable in vascular surgery. Damage to the microcirculation and endothelial glycocalyx might set up a shock with loss of circulatory coherence and organ failure. Sulodexide may help to protect endothelial glycocalyx and alleviate the ischemia-reperfusion injury.MethodsTwenty female piglets underwent surgery with a 30-min-long suprarenal aortic clamp, followed by two hours of reperfusion. Ten piglets received sulodexide before the clamp, and 10 received normal saline. Blood and urine samples were taken at baseline and in 20-min intervals until the 120th minute to analyze the serum syndecan-1, E-selectin, and thrombomodulin. Albumin and glycosaminoglycans were examined in the urine. The kidney biopsies before and after the protocol were examined by light microscopy with hematoxylin-eosin staining. The sublingual microcirculation was recorded by side-stream dark field imaging at the time as blood and urine.ResultsBased on the 2-way ANOVA testing, there was no statistically significant difference in the parameters of sublingual microcirculation. Serum markers of endothelial cell activation and damage (E-selectin and thrombomodulin) did not show any statistically significant difference either. Syndecan-1, a marker of glycocalyx damage, showed statistically significantly higher values based on the 2-way ANOVA testing (p < 0.0001) with the highest difference in the 80th minute: 7.8 (3.9-44) ng/mL in the control group and 1.8 (0.67-2.8) ng/mL in the sulodexide group. In the urine, the albuminuria was higher in the control group, although not statistically significant. Glycosaminoglycans were statistically significantly higher in the sulodexide group based on the mixed-effect analysis due to the intervention itself. Histological analysis of the renal biopsies showed necrosis in both groups after reperfusion.ConclusionAdministering sulodexide significantly reduced the level of endothelial markers of IRI. The study results support further research into using preemptive administration of sulodexide to modulate IRI in clinical medicine.
