BackgroundThe early prediction of gangrenous/perforated appendicitis is of great importance for the surgical planning, further treatments, and predicting the course of disease. Ischemia-modified albumin (IMA) was previously reported as a biomarker of various ischemia-based diseases. Our aim is to determine the predictive value of serum IMA in the severity of acute appendicitis.MethodsSixty-two patients who underwent urgent appendectomy were included in the study. Plasma level of IMA was measured after diagnosis and before treatment. All patients were classified as noncomplicated (acute) appendicitis and complicated (gangrenous/perforated) appendicitis according to histopathological findings, and comparisons were made between the groups.ResultsThe data of 62 patients with a mean age of 30.1 years were statistically evaluated. The pathological diagnoses were acute appendicitis in 33 (53.2%), and gangrenous/perforated appendicitis in 29 (46.8%) patients. There were significant differences in computed tomography (CT) findings (P = .031) and IMA (P = .012) levels between the groups. A strong positive correlation between IMA levels and CT findings was also found (Spearman ρ = +0.688, P = .003).ConclusionsThe IMA can be considered as a novel and useful marker to distinguish gangrenous/perforated appendicitis from noncomplicated appendicitis. The correlation of IMA with CT findings also enhances the predictive value of IMA.Copyright © 2016 Elsevier Inc. All rights reserved.
