- Abstract
BACKGROUND: The objective of the current study was to investigate the value of the ischemic biomarkers endothelial cell-specific molecule-1 (endocan) and signal peptide-CUB-EGF domain-containing protein-1 (SCUBE-1) in the diagnosis and assessment of earlystage and irreversible damage in acute mesenteric ischemia. METHODS: An experimental mesenteric ischemia reperfusion model was designed using 54 rats. Nine groups were created: Three sham groups [Groups I (30th minute), IV (2nd hour), and VII (6th hour)], in which only blood and tissue specimens were sampled; 3 ischemia groups [Groups II (30th minute), V (2nd hour), and VIII (6th hour)], in which blood and tissue specimens were sampled after ligation of the superior mesenteric artery (SMA); and 3 reperfusion groups [Groups III (30th minute), VI (2nd hour), and IX (6th hour)], in which blood and tissue specimens were sampled after declamping the SMA and reperfusion for 1 hour. SCUBE-1 and endocan samples obtained from blood and tissue were examined histopathologically. RESULTS: The SCUBE-1 level was higher in the ischemia groups when compared with the sham groups (p<0.05), and the endocan level was markedly different in the late ischemia (6th hour) group. When these 2 markers were used together to assess irreversible mesenteric damage in the histopathological examination, the sensitivity in distinguishing between reversible or irreversible damage was 94.1% with a specificity of 73.7%. CONCLUSION: The elevation of SCUBE-1 alone seems to be significant for predicting early mesenteric ischemia in laboratory rats. The combination of SCUBE-1 and endocan may be useful to detect irreversible intestinal damage.
