ABSTRACT

Objective:

To explore the early evaluation value of calprotectin (S100A8/A9) and ischemia modified albumin (IMA) for adult acute appendicitis (AA) and adult non-simple acute appendicitis.

Methods:

The data of 62 patients with histologically confirmed appendicitis and 57 healthy controls in the physical examination center of our hospital during the same period from May 2018 to October 2019 were collected. According to postoperative pathological data, patients with appendicitis were divided into the simple appendicitis group and the non-simple appendicitis group . The measurement data conforming to normal distribution were expressed as mean ± standard deviation (Mean±SD), and Student's t test was used for comparison between groups. S100A8/A9, IMA, C-reactive protein (CRP), procalcitonin (PCT), and blood routine parameters were compared after grouping.The area under the ROC curve (AUC) was used to evaluate the early efficacy of S100A8/A9 and IMA for acute appendicitis and non-simple acute appendicitis.

Results:

There were no significant differences in sex, age, platelet count (PLT), and red blood cell count (RBC) between the appendicitis group and healthy control (all P>0.05), while white blood cell count (WBC), CRP, PCT, neutrophils to lymphocytes ratio (NLR), S100A8/A9, and IMA levels in the appendicitis group were higher than those in healthy control (all P<0.05). The AUC of S100A8/A9 (≥366.9 μg/L), IMA (≥0.29), and S100A8/A9 combined with IMA in predicting acute appendicitis were 0.735, 0.891, and 0.913, respectively. There was no significant difference in WBC between the non-simple appendicitis group (21 cases) and the simple appendicitis group (41 cases) ( P>0.05).The levels of CRP, PCT, NLR, S100A8/A9 and IMA in the non-simple appendicitis group were significantly higher than those in the simple appendicitis group ( P<0.05). The AUC of S100A8/A9 (≥532.9 μg /L), IMA (≥0.41) and S100A8/A9 combined with IMA in predicting non-simple acute appendicitis were 0.866, 0.873 and 0.936, respectively.

Conclusions:

S100A8/A9 and IMA could be used as biomarkers for the diagnosis of AA, which have certain clinical value for the assessment of acute appendicitis and non-simple acute appendicitis.
