Background/aim: The purpose of this experimental study was to investigate the role of lipoprotein-associated phospholipase-A2 (Lp-PLA2) in the diagnosis of acute mesenteric ischemia (AMI) in the early stage. Materials and methods: Twenty-seven New Zealand rabbits were randomly divided into 3 groups in this study. Blood specimens were obtained from the groups at hours 0, 1, 3, and 6. Using the blood samples drawn from all groups, Lp-PLA2 and C-reactive protein (CRP) parameters were investigated. Results: There was a significant rise in the levels of both Lp-PLA2 and CRP starting at hour 1 (P < 0.05) (hour 1; Lp-PLA2, P = 0.003) in the ischemia group. In the sham group, the levels of Lp-PLA2 and CRP started to rise at hour 3 (P < 0.05) (hour 3; Lp-PLA2, P = 0.011). At hour 6 of ischemia, the area under the ROC curve was 100%, and the cut-off value of 63.91 ng/mL revealed a sensitivity of 88% and a specificity of 100% for Lp-PLA2. Conclusion: These findings showed the role of serum Lp-PLA2 and CRP levels in the early diagnosis of AMI. Thus, further studies are needed to describe the role of Lp-PLA2 in the early diagnosis of AMI.
