This study aims to explore the circulating levels of S100A8/A9 and S100A12 in acute pancreatitis (AP) and reveal their relationship with conventional inflammatory markers. Material and Method: Serum S100A8/A9 and S100A12 were determined in AP patients (male/female: 17/13) by using a specific enzyme-linked immunosorbent assay (ELISA) method at both onset and remission and in 30 healthy controls (male/female: 17/13). Results: Significantly higher S100A8/A9 and S100A12 levels were found in AP patients compared to healthy controls (p <0.001). Circulating levels of S100A8/9, S100A12 and C-reactive protein (CRP) were found to be elevated in AP patients at disease onset compared with remission. The correlation analysis demonstrated a significant association between S100A8/A9 and S100A12 (r=0.366, p=0.047). The cut-off level for S100A8/A9 for detecting AP was ≥54.4 ng/ml with a sensitivity and specificity of 96.7% and 73.3% (AUC: 0.958). The optimum cut-off level for S100A12 for detecting AP was ≥350.25 ng/ml with a sensitivity and specificity of 73.3% and 76.7% (AUC: 0.752) respectively. Conclusion: Circulating S100A8/A9 and S100A12 levels were found to be elevated in AP patients. Both of these markers might serve as an additional tool in the diagnostic workup in AP since S100A8/A9 and S100A12 were significantly correlated with CRP.}, number={3}, publisher={MediHealth Academy Yayıncılık}, organization={Çanakkale Onsekiz Mart Üniversitesi}
