Evaluate Established Anti-DEFA5 mAbs Diagnostic Efficacy and Safety in IBD

30% of IBD patients are misdiagnosed. This affects surgical care of patients. Investigators have unveiled a signature discriminator between UC\&CC that also predicts the outcome of IC patients into authentic UC/CC. This is a bioassay that is specific, sensitive, linear, affordable, minimal risk, non-invasive and constitutes an inexpensive, simple to use, point-of-care test format. Investigators published data which have shown robust presence of DEFA5 in the colon crypt mucosa with aberrant expression of apparent crypt-cell-like cells (CCLCs) in areas identified with ectopic colon ileal metaplasia consistent with CC. Investigators propose to validate that UC/CC, the two unsolved medical sub-types of pathology can accurately be distinguished among IC patients by examining CCLCs secreted DEFA5 levels in endoscopy biopsies instantly. Diagnostics relies on the expression/localization/activation of DEFA5 and the ectopic CCLCs in the mucosal crypt of CC patients.
