Introduction and purpose: Acute mesenteric ischemia is especially seen in the elderly population. It has an increasing incidence in today's world where the average life expectancy is increasing. Early diagnosis is the most important factor reducing morbidity and mortality, and there is still no marker with high sensitivity and specificity for early diagnosis.In this study, we aimed to find a more sensitive and specific serum marker in the early diagnosis of mesenteric ischemia by comparing thiol with the currently used markers C-reactive protein and lactate.
Materials and methods: In our study, 32 Wistar Albino male rats, 10-12 weeks old, weighing 250-300 g, were used. 32 rats were divided into 4 groups, one of which was the control group. The superior mesenteric artery of the other 3 groups was ligated. Blood samples were taken after 2 hours from the first group, 4 hours from the second group, and 6 hours from the third group. Then the rats were sacrificed. Mesenteric ischemia and its level were observed in sacrificed subjects. The samples were separated under appropriate conditions and analyzed biochemically.
Results: As the ischemia time increased, CRP increased and this increase was found to be statistically insignificant (p>0.05). The changes in lactate were found to be statistically significant (p<0.05). The difference between the changes of total and native thiol values was found to be statistically significant (p<0.05).
Conclusion: Although CRP is a non-specific parameter in the early diagnosis of acute mesenteric ischemia, lactate maintains its importance as seen in our study. Differences in total thiol and native thiol changes were statistically significant. The fact that this significant difference is observed at the 4th hour values, reveals the importance of these parameters in early diagnosis. Thanks to the economic and fast results of thiol parameters, it is thought that new studies to be added to the literature can lead to the diagnosis of mesenteric ischemia.
