Abstract
Background: Following STRIDE-II recommendations, the discovery of novel noninvasive biomarkers, beyond the use of C-reactive protein (CRP) and fecal calprotectin, remains a medical need to further improve the monitoring of patients with inflammatory bowel disease (IBD). This study aims to evaluate the potential of serum lipopolysaccharide-binding protein (LBP) in monitoring IBD activity.
Methods: This retrospective cross-sectional study included 69 IBD patients (43 Crohn's disease and 26 ulcerative colitis) and 82 controls. Serum LBP levels were measured by ELISA. Clinical, biological and endoscopic parameters were analyzed for IBD patients with no reports of missing data. Statistical tests, including nonparametric tests and receiver operating characteristic (ROC) curve analysis, were used to evaluate the diagnostic accuracy of LBP.
Results: IBD patients displayed a significantly higher LBP median [29.6 μg/ml (19.8-38.8) in Crohn's disease and 22.8 (13.7-38.8) in ulcerative colitis] than controls [5.8 (4.7-7.3), P < 0.001] with little overlapping distributions. In Crohn's disease patients, LBP levels gradually increased with endoscopic activity scores demonstrating a 1.7-fold rise in active patients compared to remitter patients ( P = 0.02). LBP level exhibited a positive correlation with CRP ( ρ = 0.75, P < 0.001) as well as fecal calprotectin ( ρ = 0.42, P < 0.01), both of which further increased when excluding cases that did not match endoscopic activity.
Conclusion: LBP might be a promising noninvasive biomarker for monitoring disease activity, especially in Crohn's disease patients. In clinical situations where current biomarkers lack sensitivity, LBP could be discriminative and help filling the gap for reliable therapeutic decisions.
期刊介绍:
European Journal of Gastroenterology & Hepatology publishes papers reporting original clinical and scientific research which are of a high standard and which contribute to the advancement of knowledge in the field of gastroenterology and hepatology.
The journal publishes three types of manuscript: in-depth reviews (by invitation only), full papers and case reports. Manuscripts submitted to the journal will be accepted on the understanding that the author has not previously submitted the paper to another journal or had the material published elsewhere. Authors are asked to disclose any affiliations, including financial, consultant, or institutional associations, that might lead to bias or a conflict of interest.
