Abstract

Background: Surgical planning is critical for ongoing treatment and prognosis of the disease's course after an appendicitis diag-nosis. Ischemia-modified albumin (IMA) has been used as a biomarker for a variety of ischemia-related disorders in the past. The aim of this study is to determine the IMA level in patients with AA and to evaluate its predictive significance.

Methods: A total of 139 participants were enrolled in the trial. After diagnosis and before surgery, the amount of plasma IMA was tested. Patients diagnosed with appendicitis in Group 1 (n=97) and volunteer surgical patients not diagnosed with appendicitis in Group 2 (n=42) were compared as the final diagnostic criterion.

Results: The data of 139 patients with a mean age of 36.15 were evaluated statistically. IMA values were analyzed in both groups. The mean IMA of all patients was 0.74±0.16 AbsU. When the two groups were compared, it was seen that IMA was statistically higher in Group 1 than in the control group. While the area under the curve for IMA was 0.670, the sensitivity for the cutoff value of 0.715 was 68%, the specificity was 62%.

Conclusion: Our study shows that IMA values provide significant results in predicting acute appendicitis.
