Serum-soluble receptor for advanced glycation end-products values might have diagnostic and prognostic significances in ulcerative colitis

Aims: There is evidence of anti-inflammatory qualities associated with a soluble receptor for advanced glycation end products (sRAGE). We aimed to evaluate whether serum sRAGE levels of patients with inflammatory bowel diseases (IBDs) could serve as a biomarker by utilizing several clinical and laboratory models of disease activity for these individuals. Methods: This case-control study included 77 ulcerative colitis (UC) patients (51 males and 26 females), 49 Crohn’s disease (CD) patients (33 males and 16 females) and 54 healthy controls (38 males and 16 females). In UC, the UC Mayo Clinical Scoring system (MCS) was used for the clinical and endoscopic features. The histological activity index (HAI) of UC patients was determined by Truelove and Richards method. The Crohn's disease activity index (CDAI) was utilized for CD patients. Results: In comparison to the control group, the median sRAGE concentrations in UC patients were significantly lower. [911.17 ng/L (322.91-1682.19 vs 1420.96 ng/L (816.68-2320.08), respectively, p=0.008)]. The patients with CD did not significantly differ from the other groups. The MCS and HAI values of UC patients negatively correlated to the serum sRAGE values (rho=-0,610, p
